How Is Subjecthood Possible: Symmetry, Negativity, and Subjecthood
主体性何以可能：对称、否定性与主体性

Author's Note

This is the fourth paper in the Self-as-an-End theory series. The first paper, "Systems, Emergence, and the Conditions of Personhood" (Zenodo, DOI: 10.5281/zenodo.18528812), analyzed the systemic and institutional tier. The second paper, "Internal Colonization and the Reconstruction of Subjecthood" (Zenodo, DOI: 10.5281/zenodo.18666588), analyzed the individual and relational tiers. The third paper, "The Complete Self-as-an-End Framework" (Zenodo, DOI: 10.5281/zenodo.18727326), unified all three tiers into an integrated framework. This paper provides ontological grounding for the preceding three.

This is a philosophical framework paper, not an empirical scientific study. The physics referenced herein serves to establish an axiomatic foundation and does not constitute novel claims in physics.

I thank Zesi Chen. The core arguments of every paper in this series have undergone her rigorous and uncompromising critical examination. Her ability to identify theoretical weaknesses has been the decisive force behind the framework's continuous reinforcement — each version she rejected forced me to re-examine the foundations of my arguments, ultimately pushing the framework to deeper levels. Without her negativity, the quality of these papers would not be what it is today. She declined co-authorship, but her contribution to this series far exceeds what any acknowledgment can express. I do not merely appreciate and trust her remainder — I love her remainder; I love her.

Chapter 1: The Problem

1.1 The Presuppositional Gap in the Framework

The first three papers in the Self-as-an-End theory series presupposed that "humans are subjects." This presupposition was sufficient for analyzing the conditions of subjecthood — the first paper analyzed how institutional emergence erodes the space of personhood, the second analyzed the cross-tier transmission of internal and intimate colonization, and the third unified all three tiers into a single framework while providing philosophical grounding for negativity and positivity. Together, the three papers established a complete structural theory of the conditions of subjecthood.

However, this theory has already reached the boundaries of its presupposition in application. The first applied paper introduced a conceptual distinction between "quasi-subjects" and "true subjects" in analyzing AI systems — a distinction that presupposes clear criteria for determining subjecthood, which the first three papers never established. The third paper defined negativity as "the refusal to be treated as a non-subject" and positivity as "the recognition of other subjects," but these definitions still operate within subjecthood — they describe two constitutive dimensions of subjecthood without answering where subjecthood itself comes from.

These concepts require two foundations: what negativity actually is (definable), and what subjecthood actually is (requiring description).

1.2 Three Questions That Do Not Share One Answer

This paper asks three things. They are answered separately here; none answers for another, and they are not chained together.

Question one (normative). On what does a subject's standing as an end rest? Answered by the normative premise this paper openly undertakes (Chapter 2).

Question two (scientific). How does the capacity to recognize and perform negation arise and get realized in nature? This paper does not adjudicate it; it only leaves it an independent research position and one testable physical route (Chapters 3 and 9).

Question three (limit). Where does subjecthood ultimately come from? This paper does not answer it; it only registers it under a limit-name (2.7).

The first three papers presuppose "humans are subjects" and build a structural theory of the conditions of subjecthood. This paper digs one layer deeper, but it does not dig one hole: questions one and two each land on their own ground, and question three is left blank.

The old assembly ran: from a physical fact (the macroscopic remainder) to the capacity to refuse, and from that capacity to a subject's standing as an end. This paper does not travel that road. A physical account of capacity does not issue standing; a normative undertaking of standing does not guarantee that capacity is realized; and neither takes the ultimate source as a premise. These three breaks are this paper's architecture, not its debts.

Where this paper stands in the series: the first three are a structural theory of conditions — given the presupposition "humans are subjects," they analyze the structural conditions under which a subject maintains its standing as an end. This paper separates two things: that presupposition itself is domiciled here as an openly undertaken normative postulate (2.3), while the capacity side's physical account travels the scientific route (Chapter 3).

1.3 Why Existing Definitions Are Insufficient

Definitions of subjecthood in the history of philosophy have almost without exception proceeded from the first person. Descartes' "I think, therefore I am" anchors subjecthood in the self-confirmation of thought. Kant's transcendental subject presupposes a unity of apperception. Husserl's phenomenological reduction traces subjecthood to the structure of intentionality. Heidegger's analysis of Dasein begins from "being-in-the-world."

These definitions face two shared problems.

First, they all proceed from the first person. This means that the determination of subjecthood can only be performed by the subject itself — from the third-person perspective, we can never confirm whether another being is "truly" a subject. This limitation is perhaps tolerable when dealing with human-to-human relations (we default to assuming that other humans also possess a first-person perspective), but when dealing with animals, AI, and borderline cases (patients in vegetative states, infants), it becomes a fundamental obstacle.

Second, most of them conflate consciousness with subjecthood. Nagel's "what is it like to be a bat" asks about conscious experience (qualia), not subjecthood. Searle's "ontological subjectivity" effectively binds subjecthood to the irreducibility of consciousness. But are subjecthood and consciousness the same concept? Does a being with negativity necessarily have consciousness? Does having consciousness necessarily entail subjecthood? These are open questions that should not be prejudged at the level of definition.

This paper's strategy is to handle these two problems separately. Negativity — the physical condition of capacity-activity — can be defined from the third person, without any participation of the first person. Subjecthood — grounded in but not identical to negativity — cannot be scientifically defined, but can be precisely described. Consciousness — where the hard problem resides — is not addressed in this paper and is left for future research.

1.4 The Two Routes of This Paper

The normative route (Chapter 2). One zero point is shared — Negativa cannot be negated — cited by domicile, and it guarantees nothing about this paper's content. In this series this paper domiciles one core normative postulate: a human being is an end in itself. It is openly undertaken, it can be refused, and whoever refuses it domiciles a branch of his own. From it follow two consequences: standing is not conferred by any test, and the guard rail. The question of the condition-source is given no objectual answer; it is registered under a fourth limit-name.

The scientific route (Chapters 3 and 9). If ontic randomness exists, negativity can be defined as the remainder that persists at the macroscopic scale — that part of a system's total state which cannot be exhaustively explained by external conditions. This definition rests entirely on third-person scientific determination and depends on no first-person concept. Physics here bears testability, not standing as an end.

There is no inferential bridge between the two routes. "Negativity" is one word doing two jobs: on the scientific route it names the macroscopic remainder; on the normative route it names one dimension of subject activity. A shared root is not a shared undertaking (3.8).

Subjecthood cannot be scientifically defined. This paper keeps that judgment, but states it precisely: what no single scientific criterion can exhaust is the composite of capacity-activity and relational achievement. It does not mean that standing as an end must await some recognition. Standing is borne by the postulate; it is conferred neither by a definition nor by a test (2.3, 2.4).

1.5 The Physical Axiom and Its Office

All derivations on this paper's scientific route rest on the following axiom:

If ontic randomness exists — that is, if there exist events such that for any deterministic function f and any complete set of prior conditions C, the outcome O ≠ f(C) — then the following derivations hold.

In current physics, quantum randomness is the only known source of ontic randomness. The experimental verification of Bell's inequalities rules out local hidden-variable theories and provides this axiom's strongest present empirical support. This paper does not argue for the axiom's physical basis; it proceeds philosophically from the axiom.

Office. What this axiom bears is testability, not standing as an end. It gives negativity a third-person-determinable physical route, so that this paper's scientific route has somewhere to fail. It does not vouch for who is an end, nor is it a premise of this paper's normative route.

The axiom's conditional form is deliberate, and the firewall runs both ways:

• If future physics overturns the existence of ontic randomness, this paper's Chapter 3 definition of negativity must be rebuilt, and Chapter 9's predictions lapse with it.
• But Chapter 2 is unaffected — standing as an end and the guard rail depend only on the postulate and the domain of objects, not on any physical axiom.
• The first three papers are likewise unaffected — their operation requires only the presupposition "humans are subjects."

This paper is an optional deep grounding for the first three, not a necessary load-bearing structure.

1.6 Paper Structure

Chapter	Core task	Epistemic status
Chapter 2	A subject's standing as an end	An openly undertaken normative premise and its consequences
Chapter 3	Define negativity	Scientific definition (third-person determinable)
Chapter 4	Describe subjecthood	Description of capacity-activity and relational achievement; confers no standing
Chapter 5	Negativity and cultivation	The interface between this paper and the first three
Chapter 6	Negativity, subjecthood, consciousness	Distinguishing three concepts; open questions
Chapter 7	Criteria and boundary cases	Application and calibration of the framework
Chapter 8	Theoretical positioning	Dialogue with existing theories
Chapter 9	Non-trivial predictions	Testable implications on the scientific route
Chapter 10	Conclusion	Summation, refutation table, open questions

There is no inferential relation between Chapters 2 and 3. Chapter 2 comes first not because it matters more, but because it does not depend on Chapter 3; placing it later would suggest it waits for physics to speak.

Chapter 2: A Subject's Standing as an End

This chapter answers question one: on what does a subject's standing as an end rest? It depends neither on Chapter 3 nor on any physical axiom.

---

2.1 There Is Only One Zero Point

SAE's sole axiom is Negativa cannot be negated: Negativa is a performable demarcating operation; deny it, and the act of denial has already performed it. The axiom has no domicile; its guarantee attaches to the act of denial itself, and it spans every field, level, branch and postulate (Methodology 0 · Negativa, V2, §2).

The relation between the axiom and the rest of SAE is called a zero point, not a grounding. The zero point vouches for the content of no series; it is merely the one place no series can get around.

Two consequences follow, and this paper observes both.

First, Negativa does not ground subjecthood. To ground philosophy is itself an act of demarcation, and so lies under the zero point too; Negativa cannot ground itself (same paper, §6). To ask the zero point to vouch for specific content such as "a human being is an end" is to lend the zero point's guarantee to a particular claim — that is usurping the zero point (First Critique, On Illusion, §2). This paper does not borrow it.

Second, this paper domiciles by the adjacency format. The zero point is shared; the methodology series' postulates are cited by domicile; this series' postulates are domiciled in this series (same paper, §8). This chapter is that format executed on the subjecthood side.

2.2 A Limit on Argumentative Responsibility

Limit One. A determination of who is an end is itself a judgment with a position, premises and a range; being able to make that determination does not by itself confer on the one making it the standing to allocate standing as an end.

This paper does not derive "a human being is an end" from this. It is a limit on argumentative responsibility, not a layer of guarantee.

The word "position" has three senses, which must be kept apart:

	Sense	Does Limit One reach it?
i	Where a given judgment actually issues from	Granted; but this is nearly trivial
ii	Whether someone has the standing to adjudicate or certify	Yes: being able to judge is not having that standing
iii	Whether the one judged has standing as an end	No; answered by the postulate (2.3)

Granting (i) is not granting (ii), still less having an answer to (iii). Someone who claims "my test decides who has standing as an end" may freely grant that he is judging from a position — what he denies is that the standing is not conferred by a test, not that he is judging. So pointing out that he is already judging does not render his claim performatively self-defeating; the brazenness of his test must be criticized on normative grounds, and cannot be shown logically impossible by noting that it, too, is a judgment.

Limit One does one thing only: a judge does not acquire the power to issue standing for others merely by having opened his mouth. That one thing this paper uses.

---

2.3 This Paper's Core Normative Postulate

Postulate One. A human being is an end in itself.

This postulate is a normative premise this paper openly undertakes. It is not derived from the operation of negation, and it does not pose as the result of any physical test.

Technical sense. The standing as an end that Postulate One asserts is the non-meritocratic normative standing of every person within the domain of objects — not a reward for acquiring some capacity or receiving some recognition. Hence within the same domain, a person cannot be re-judged as lacking standing as an end merely because his capacities have changed.

Refusable. Whoever refuses Postulate One domiciles a branch of his own, and that branch may be inhabited. He does not thereby lose the capacity to think or to negate, and this paper does not judge him a bad person.

The cost is a burden of proof and a transmission ledger, not politeness. What the refuser loses is the entitlement to have this paper's premise vouch for his own conclusions: he may not cite, as a theorem needing no further argument, the guard rail this paper derives from the postulate. Losing a ground is not being shown false; he may reach the same conclusion on other grounds, and this paper does not predict that his conduct will be worse or his outcomes poorer.

Dependency transmission ledger

Replace or refuse what	What this paper must re-audit	What is not thereby cancelled
Postulate One	This paper's ground for 2.4 and the guard rail; the inference that standing does not float with capacity or recognition	That judging occurs; acts of negation; the truth or falsity of physical research
The distinction between standing and capacity	The guard rail; the appraisal of complete deprivation	The actual evidence of some change in capacity
Some physical hypothesis	That explanation of the macroscopic remainder and the predictions depending on it	Standing as an end within an independent normative premise
The limit-name's usage rule	The exclusions and predication limits under that name	Research into other specifiable sources; questioning of Postulate One itself

A branch may be inhabited; that does not mean this paper declines to argue with it. Against a position that fixes standing by a capacity threshold, this paper questions its reasons, range and costs, and criticizes its consequences; it does not let registering a branch substitute for argument, nor announce by that registration that argument has ceased. It only declines to use the zero point to pronounce the opponent unintelligible.

---

2.4 Standing Is Not Conferred by Any Test

Standing is not conferred by any test. Within an already specified domain of objects, no appraisal of capacity or of recognition issues a certificate of standing as an end.

This is Postulate One's normative consequence in this paper, not a premiseless performative theorem.

It states what this paper itself does; it is not a claim about what attitude anyone ought to hold. This paper advances no such claim and grounds no arrangement that presupposes some default attitude: from "standing does not vary with any test" to "I must not demand that you prove yourself before I treat you as an end" there is a further step about how persons are to be treated, and this paper does not build it. That undertaking has its own address.

It does not abolish factual verification — whether some capacity remains, whether some response occurs, can be reliably appraised in the third person — it denies only that such appraisals carry a licence to confer or revoke standing as an end. Nor does it settle in advance the boundary of the domain of objects (10.4).

This consequence is not built on measurement limits. A capacity may be reliably confirmed lost while standing as an end is not thereby revoked; that is precisely what this paper means to hold. To say instead "because capacity cannot be tested at all, we default to it" would make the default vulnerable again the moment detection improves.

2.5 Standing and Realization

"End in itself" carries two discussions in this series, and this paper separates them by address.

Name	Sense	Domicile	What failure looks like
End in itself (standing sense)	The non-meritocratic normative standing of every person in the domain	This paper, 2.3	This paper itself revoking it, within the domain, on grounds of capacity or recognition
End in itself (realization sense)	How far individual, relational and institutional conditions actually support subjecthood	Second paper, §6.3	Conditions damaged, imbalanced, colonized

The second paper's §6.3 writes "a subject as an end in itself" as "a state that requires the coordinated coexistence of multi-layer structural conditions to be maintained" — that is realization. This paper's 2.3 speaks of standing. Taken as one object of judgment, the two collide.

A split of address must be earned, not had by renaming. This paper pays four things for it:

1. Separate senses and separate objects of failure. Standing is not a performance score; realization is not standing conferred once more.
2. The same case may yield different verdicts. Standing intact, realization poor, is a combination with content, not one defined away in advance.
3. Neither column lends its ground to the other. Successful repair in reality does not by itself establish standing; standing undertaken does not guarantee that real conditions appear.
4. Pay the cost in sources and dependencies. What the original text says, what is this paper's new reading, and what must be settled by the earlier paper, are registered item by item.

The second paper does not hold only a vanishing "end in itself": it sets out normative anchors at §1.4 and §4.1—§4.2 while discussing structural conditions and ecological achievement at §2.3 and §6.3. So this split has real contextual warrant and does not impose a new sense on an old text. But the second paper has not, in this paper's vocabulary, fixed that "full standing as an end is not revoked by changes in capacity or recognition"; that this reading can be drawn from the original does not mean that all of the original's inferences about "the subject becomes a tool" or "the subject no longer exists" have already been gathered under it. This paper does not let a split of names supply either side's missing argument; which older sentences must be explicitly confined to the realization layer is to be registered correspondingly by the second paper.

2.5.1 Indices: Three Senses of Subjecthood, Two of End in Itself

These are not five parallel levels.

Index	Its work in this paper	Relation to "realization"
Normative standing	Who must still be treated as an end; borne by Postulate One and the domain	Not a score or product of realization
Capacity-activity	What recognition, negation and choice can actually occur	One condition of concrete realization, not the whole of it
Relational achievement	How far mutual recognition, support or joint activity actually obtains	One relational dimension of realization; it does not exhaust the individual and institutional dimensions
End in itself (realization sense)	How far individual, relational and institutional conditions actually support subjecthood	The composite question of realization; must keep its concrete relational and temporal indices

Relational achievement is not realization as a whole. Capacity intact does not guarantee the relation is respected; being well treated in a relation does not show that all capacities and institutional conditions are healthy.

2.5.2 Standing Does Not Vanish with Realization, and Still Excludes Something

It excludes at least this reason, inside this paper:

He can no longer refuse, and no one recognizes him, so there is no need to include him as an end in appraising this matter.

That reason is refused by Postulate One. How to safeguard, who specifically bears it, how conflicts over resources are allocated — those are a further step, not settled by this sentence.

A normative requirement unexecuted in reality is not a normative judgment without content. But neither does this paper claim to have repaired any real predicament. What it means to hold is this: real failure cannot be rewritten into the subject's no longer being worth such treatment.

This non-revocation operates only within the domain of objects and the temporal range this paper specifies. One may not evade it by deleting the person from the domain after the harm has occurred.

---

2.6 The Guard Rail

Guard rail. Within the domain of human objects this paper undertakes, impaired capacity, coerced change, or the absence of others' recognition does not constitute a ground for revoking standing as an end. Such changes alter the conditions of exercise and realization; and the act imposed, together with its results, cannot be used to issue that act a retroactive justification.

The guard rail is Postulate One's normative consequence, not a premiseless performative theorem. A conditional inference does not lose content because its normative premise is open, nor need it erect another axiom to look independent.

2.6.1 Results Do Not by Themselves Issue Justification

Limit Two. Having reduced another to a state unable to refuse, express or appeal does not by itself show that he lacked standing as an end when the act occurred, nor by itself render that act justified. How other results enter appraisal still depends on criteria grounded elsewhere; it is not answered by an incapacity or a cancellation of status that the agent brought about himself.

Limit Two blocks one specific route to exculpation: the perpetrator deprives the other of capacity, then invokes that result to say no subject requiring respect existed beforehand, so the act never violated anyone's standing. That route cannot be travelled on results alone.

Limit Two does not claim that no result can ever provide justification for an act. Under independent, public criteria, results may enter appraisal; where a rule stipulates in advance that avoiding some grave harm is a factor of appraisal, results that later appear may serve as evidence of that factor. This paper does not exclude such discussion.

Nor does Limit Two single-handedly block every capacity-based theory of standing. An opponent who adopts a capacity threshold from the outset, rather than invoking results after the fact, disputes with this paper the ground of standing itself; that dispute is handled by Postulate One and the apparatus of 2.3, not by Limit Two.

2.6.2 Domain and Temporal Range

The "imposed" in the guard rail cannot by one word decide the domain of objects. Birth is a life process and is not automatically an injurious external imposition; development may be self-arising or externally supported; support that changes capacity does not by itself confer or raise standing as an end. One already within this paper's domain who acquires a new capacity does not thereby acquire a higher normative standing.

The domain of objects this paper currently undertakes: individual human beings now living. The guard rail and 2.4 operate within that domain; this paper undertakes non-revocation for every person in it.

Non-human systems are recorded separately. What Chapters 7 and 9 determine about non-human systems is their capacity-activity — whether a macroscopic remainder is present, and where on the spectrum they fall. Those determinations do not constitute admission. If one determination of capacity could bring a system into the domain, that would be capacity conferring standing — precisely the step 2.4 forbids. So an AI with a macroscopic remainder has a definite position in this paper: its capacity-activity is determined, and on what its standing as an end would rest is not adjudicated here. This does not close that question; it keeps a single capacity test from closing it in advance.

The boundary of the domain itself — the beginning and end of human life, how those not yet born enter a continuing domain, and whether and by what rule non-human systems are included — is not settled here (10.4). Three things must be kept apart: subsequent change in the same object; mistaking the object in the first place; and later modification of the boundary rule. One may not use the name "correction" to hollow out a non-revocation already undertaken.

---

2.7 Two Senses of "Source," and a Fourth Limit-Name

"Source" has two senses, to be separated first (Methodology 0 V2, §6):

• Capacity-source: how organisms came to have the capacity to draw distinctions and to say "no." This can be researched; it belongs to science, and this paper does not adjudicate it (Chapter 3 gives it a physical route, not an answer).
• Condition-source: why there is subjecthood to speak of at all. This sense is given no objectual answer; it is marked only by a limit-name.

Limit-name Four. The source of subjecthood: this paper's bounding name for the question of the condition-source.

It stands alongside the thing-in-itself, chaos, and the source of Negativa without being identified with any of them. It is a commitment of usage, not a discovery. Four limits, none dispensable:

1. It preserves only that one unanswered question of the condition-source; it does not serve as a scientific answer about the arising of capacity.
2. The refusal of objectual answers is a usage rule under this one name; it does not declare all branches' research into sources invalid.
3. It is not used to prove Postulate One, nor to block inquiry into that postulate's reasons, range and costs. "Why I undertake that a human being is an end" and "where subjecthood ultimately comes from" are two questions and are not packed into one name.
4. This paper's domiciling a fourth name does not mean Methodology 0 has registered a fourth name on this paper's behalf, still less that a fourth entity has been discovered.

The relation between the source of Negativa and the source of subjecthood is not adjudicated here. Similarity in the structure of two such regresses is not by itself ground to assert that they refer to the same thing; and a difference in definitions is not by itself ground to assert that they refer to different things.

---

Chapter 3: The Definition of Negativity

This chapter completes the first step of the path: defining negativity from the third person.

3.1 Ontic Randomness

There are two fundamentally different types of randomness.

Epistemic randomness is unpredictability arising from ignorance. The outcome of a coin toss is random to us, but this randomness is rooted in our lack of complete information about the coin's initial conditions. In principle, given complete initial conditions and the laws of mechanics, the coin's landing side can be fully predicted. Behind epistemic randomness lie deterministic causes that are merely hidden from us.

Ontic randomness is unpredictability for which no deterministic cause exists. It is not that "we do not know the cause" but that "there is no cause." The outcome of an event cannot be derived from any deterministic function applied to prior conditions — not because the function is too complex or information is incomplete, but because no such function exists.

This distinction is not purely philosophical speculation. In current physics, the standard interpretation of quantum mechanics treats quantum randomness as a candidate source of ontic randomness. The experimental verification of Bell's inequality has ruled out local hidden variable theories — that is, it has ruled out the most natural version of the explanation that "quantum randomness is actually epistemic randomness; we just haven't found the hidden variables yet." While alternative explanations such as non-local hidden variable theories and superdeterminism remain logically possible, ontic randomness is the most supported understanding within the current physics consensus.

This paper does not argue for the physical basis of ontic randomness. This paper's axiom is conditional: "If ontic randomness exists, then the following derivations hold." Physics provides the best evidence supporting this axiom, but whether the axiom holds is ultimately a question for physics, not philosophy, to answer.

3.2 Statistical Smoothing

Even if ontic randomness exists at the microscopic level, it does not in most cases produce observable effects at the macroscopic level.

A glass of water contains approximately 10²⁵ molecules. Each molecule's behavior includes ontic randomness at the quantum level. But when the behaviors of 10²⁵ molecules are statistically aggregated, the randomness is smoothed out — the macroscopic behavior of water (temperature, pressure, flow) can be fully described by deterministic thermodynamic laws. The ontic randomness of individual molecules has not disappeared, but it has become invisible at the macroscopic level.

This smoothing is an inevitable consequence of statistical laws. The law of large numbers guarantees that when sufficiently many independent random events are aggregated, the overall behavior tends toward determinism. Ontic randomness is statistically "averaged out" at the macroscopic level.

This leads to a key definition:

Definition 1: Macroscopic = the scale at which ontic randomness has been smoothed out by statistical laws.

"Macroscopic" here is not a definition about physical size but about statistical behavior. A system is at the macroscopic scale when its behavior can be adequately described by deterministic laws — when ontic randomness at this scale no longer produces observable deviations.

A rock is macroscopic. Water is macroscopic. The atmosphere is macroscopic. In these systems, quantum randomness genuinely exists at the microscopic level but has been completely smoothed out by statistical laws, leaving no impact on macroscopic behavior.

3.3 The Remainder

Now consider a special case: a system whose macroscopic behavior cannot be fully explained by external conditions.

Let S be the total state of an entity and E be all external conditions. If there exists a deterministic function f such that S = f(E), then all of this entity's behavior can be derived from external conditions — it has no part that is not determined by the external. A rock satisfies this condition: given a rock's chemical composition and the physical environment it inhabits, all of the rock's macroscopic behavior can be fully predicted by physical laws.

But if no such function exists — if for any f, S ≠ f(E) — then a difference exists:

R = S − f\*(E) ≠ 0

where f\* is the best approximation function for S. R is the remainder — the portion of the system's total state that cannot be exhaustively explained by external conditions.

The existence of a remainder means that some part of this system's behavior does not come from external conditions. This "part that does not come from the external" must have another source — and under the axiom of ontic randomness, this source ultimately traces back to ontic randomness. The remainder is the "trace" of ontic randomness at the macroscopic level.

3.4 The Definition of Negativity

Combining the preparations of the preceding two sections, negativity can be precisely defined:

Definition 2: Negativity = the remainder that persists at the macroscopic scale.

This definition has four elements, each serving a distinct theoretical function.

"Macroscopic scale" excludes individual quantum events. The decay of a single radioactive atom involves ontic randomness, but this does not constitute negativity — it does not produce a remainder at the macroscopic level. Negativity requires that ontic randomness "survive to" the macroscopic level rather than vanish in statistical smoothing.

"Persists" indicates that ontic randomness has not been completely smoothed out by statistical laws. This implies some form of organization — if the remainder were purely unorganized random fluctuation, the law of large numbers would smooth it out. The remainder's survival at the macroscopic scale means the system has in some way preserved the macroscopic effects of ontic randomness.

"Remainder" is the portion of the system's state that cannot be exhaustively explained by external conditions. It is not a special substance, not a mysterious force, but a mathematically definable difference: total state minus the portion that external conditions can explain.

The entire definition is determinable entirely from the third person. There is no need to ask the system "do you have a remainder," no need to assume the system has a first-person perspective. One need only observe the system's macroscopic behavior from the third person and examine whether there exists a portion that external conditions cannot exhaustively explain.

Negativity is therefore the first definition of negativity that does not depend on first-person concepts. Traditional definitions of subjecthood (Descartes, Kant, Husserl) all require proceeding from the first person — "I think," "transcendental apperception," "intentionality." This paper's definition of negativity operates entirely within the third-person domain.

3.5 The Relationship Between Ontic Randomness and Negativity

Ontic randomness is a necessary condition for negativity, not a sufficient one.

Having ontic randomness does not entail having negativity. A single quantum event has ontic randomness but does not produce a remainder at the macroscopic scale. A glass of water contains quantum randomness in all its molecules, but the water's macroscopic behavior has no remainder. From ontic randomness to negativity, an intermediate step is required: ontic randomness must in some way survive to the macroscopic scale, resisting statistical smoothing.

This "survival mechanism" is an independent scientific question — a question for physics and biology, not philosophy. Possible mechanisms include the amplification of quantum effects in neural systems, the functional utilization of quantum noise by biological organisms, and the sensitive amplification of microscopic perturbations by chaotic systems. The specific content of these mechanisms does not affect this paper's definition.

Here, a possible objection must be directly addressed: deterministic chaotic systems also produce unpredictable behavior — is ontic randomness necessary to produce a remainder? The answer is: yes. The unpredictability of deterministic chaotic systems is epistemic randomness, not ontic randomness. Chaotic systems are extremely sensitive to initial conditions, making it practically impossible for us to predict their long-term behavior — but this unpredictability can in principle be eliminated. If a Laplace's demon possessed complete knowledge of a chaotic system's initial conditions and dynamical equations, it could fully predict the system's behavior. The total state S of a chaotic system is in principle equal to f(E) — only f is extraordinarily complex and practically incomputable for us. Therefore chaotic systems have no remainder, only insufficiency of our computational capacity. The definition of remainder requires a difference that cannot in principle be eliminated by any deterministic function — not a difference that is merely difficult to compute in practice. Only ontic randomness can provide this in-principle ineliminability.

This is intentional boundary-drawing, but not an exemption. This paper's definition of negativity does not depend on any one specific explanation of the survival mechanism; it does depend on there being some survival mechanism.

This paper therefore lists this as a proof task still to be delivered, rather than eliding it with an arrow:

Proof task one (macroscopic retention). Ontic randomness does not automatically guarantee a macroscopic remainder. For a specified class of systems, the mechanisms or hypotheses of macroscopic retention or amplification must be set out, together with the expected direction and the failure cases. If for some class of systems it can be shown that no such mechanism is possible, the definition of negativity lapses for that class.

Failure of this task is one of the ways this paper's scientific route fails (10.3), not a piece of subsequent work unrelated to the definition.

3.6 Precision of Definition and Imprecision of Application

The definition of negativity is precise: the remainder that persists at the macroscopic scale. This definition has no gray area — either there is a remainder or there is not.

But the precision of the definition does not equal the precision of application. Applying this definition to specific entities faces two empirical difficulties.

The first difficulty: how to determine whether a given behavior is remainder or merely an inadequate model? When we observe a system exhibiting unpredictable behavior, this may be ontic randomness surviving to the macroscopic level (a genuine remainder) or simply our not yet having found the deterministic function f (an epistemological blind spot). Are the individual behavioral differences among honeybees remainder or neural circuits we have not yet understood? This question can in principle be progressively clarified with scientific progress — more precise models can narrow the epistemological blind spot — but at any given moment, we cannot be fully certain where the observed unpredictability comes from.

The second difficulty: even once the existence of a remainder is confirmed, "how much" remainder cannot be precisely quantified. Negativity is a spectral concept — the negativity of a honeybee (if it exists) is "thinner" than a horse's, and a horse's is "thinner" than a human's — but we cannot say that a honeybee's negativity is 0.3 while a horse's is 0.7. The spectrum is real, but it has no calibrated scale.

These two difficulties are not defects of the theory but properties of the object itself. The definition can be precise, determination can only approximate, and quantification is impossible. This parallels the situation of many scientific concepts — the definition of turbulence is clear, but determining "how turbulent" a specific flow is is not always precise.

3.7 Verification

The following verification table applies the definition of negativity to six types of entities. This table represents current best judgment, not a final verdict — it reflects the most reasonable assessment under current scientific understanding and may be revised as science progresses.

Entity	Negativity Determination	Detection status (3.8.1)	Basis
Rock	Definitely absent	Not detected	A micro-level source of ontic randomness is present, but no known mechanism of macroscopic retention, and macroscopic behavior is exhaustively explicable by deterministic physical laws with no residual
Single quantum event	Not applicable	Not applicable	Has ontic randomness but not at macroscopic scale; this axis does not engage
Honeybee	Possibly present	Not discernible	Individual-level persistent behavioral differences, cross-modal learning, situational flexibility — remainder evidence exists but is weak; epistemic randomness explanations cannot be excluded
Horse	Very likely present	Not discernible	Stronger remainder evidence at behavioral level; mammalian nervous system complexity makes ontic randomness survival to macroscopic level more plausible
Human (normal adult)	Definitely present	Not on this axis	First-person confirmation — I know that my behavior is not fully determined by external conditions
Quasi-subject AI (classical hardware)	Definitely absent	Non-existent	Deterministic system; no source of ontic randomness; no remainder

This table presents five determination tiers: definitely absent, not applicable, possibly present, very likely present, definitely present. But determination tier and detection status are two axes and must be read separately (3.8.1).

Once the two axes are separated, a difference the grades had concealed becomes visible at once: rock and quasi-subject AI share the tier "definitely absent," but their grounds are of different kinds.

• The quasi-subject AI is non-existent: classical hardware has, by its constitution, no source of ontic randomness at all. This is an argument about the system's constitution, not about residuals, and is therefore the strongest kind of determination in this table. It is for the same reason reversible — if the hardware is changed to an architecture possessing ontic randomness, this row's constitutive premise no longer holds (7.2.1).
• The rock is not detected: a rock is made of quantum matter, so a micro-level source is present; what is missing is a mechanism of macroscopic retention (3.2, statistical smoothing). By 3.8.1's own discipline, a zero residual cannot certify that "every possible external explanation fails," so this row reaches not-detected and no further — however high its evidential strength in practice.

The honeybee and horse rows already state in their criteria that "epistemic randomness cannot be ruled out," which is exactly not discernible: they differ in strength of evidence, not in detection status. And the human row rests on first-person report, which does not lie on this axis at all.

This labelling changes no row's determination; what it changes is how those determinations may be cited: not-detected may not be cited as non-existent, and not-discernible may not be cited for a conclusion on either side.

The "definitely present" tier warrants special explanation. It includes only normal adult humans because only beings capable of first-person reports can provide this level of evidence. I know that my behavior is not fully determined by external conditions — this is not a scientific observation but a direct first-person report. This type of report constitutes the strongest evidence because it does not require inferring the existence of a remainder from the third person but is directly confirmed by "the system that possesses the remainder itself."

All other entities' negativity determinations can only be approximated from the third person — observing their macroscopic behavior, assessing the likelihood that a remainder exists — but can never reach the certainty of first-person confirmation. The determination gradient from honeybee to horse to human reflects not the strength of negativity itself but the strength of evidence available to us from the third person.

3.8 Non-Entailment

The word "negativity" carries three things in this series: the demarcating operation (Negativa, Methodology 0), the macroscopic remainder (this chapter), and normative refusal (the third paper). The three do not certify one another. A shared root is not a shared undertaking.

What is in hand	What does not by itself follow
This time some assertion really was negated	The performer has a physical process undetermined from outside
Some random variation was found	It is a person's refusal or self-set end
Normative refusal holds	A particular account of its physical realization is correct
Some capacity was reliably detected, or its absence confirmed	A person's standing as an end is conferred or revoked by that test

If a correspondence is to be rebuilt, give the bridge item by item; terminological kinship is no substitute for proof.

3.8.1 Not Detected, Not Discernible, Not Existent

The verification table of the previous section gives the current best judgment. In reading it, three things must be kept apart:

• Not detected: with the data and models at hand, no remainder has been seen.
• Not discernible: with the data and models at hand, remainder and epistemic randomness cannot in principle be told apart.
• Not existent: there is no remainder.

A residual against one set of models on finite data cannot, on the strength of "the best fit still leaves a gap," certify that every possible external explanation fails; conversely, a good fit does not show that no remainder exists. This paper's limits on the ideal f(E) versus actual testing (3.6) are retained in full here: epistemic difficulty must not be renamed an objectual fact, and a failure to detect must not be read as the non-existence of the object.

This distinction constrains Chapter 9: not being discernible does not show there is no remainder, and detection results change no one's standing as an end (2.4).

The verification table of the previous section has already been labelled row by row against these three grades. The result is at 3.7: of six rows, one non-existent, one not detected, two not discernible, one not applicable, and one not on this axis.

Chapter 4: Describing Subjecthood — Capacity-Activity and Relational Achievement

This chapter describes the two indices the word "subjecthood" carries in this paper: capacity-activity and relational achievement. It confers no standing as an end; standing is borne by Chapter 2's postulate and is decided by none of this chapter's descriptions or thresholds.

4.1 Negativity Is Not Subjecthood, and Subjecthood Is Not One Thing

The definition of negativity is a scientific determination (Chapter 3). "Subjecthood" is not an object of determination but a shared name for three things (2.5.1):

• Normative standing — who must still be treated as an end. Borne by Postulate One; not in this chapter.
• Capacity-activity — what recognition, negation and choice can actually occur. Appraisable in the third person; 4.2—4.3.
• Relational achievement — how far mutual recognition, support or joint activity actually obtains; 4.4—4.5.

Honeybees may have negativity — a remainder may exist in their macroscopic behavior. Horses very likely have negativity — the behavioral evidence of a remainder is stronger. These are judgments about capacity-activity, and science may improve or overturn them.

Whether a person is recognized, well treated, seen as a person in a relation, is a judgment about relational achievement. It is real, it matters, and it can fail.

The three do not entail one another. Negativity is a necessary condition of capacity-activity: a system wholly determined by external conditions has no part that is its "own," so there is no speaking of its own refusal. But from capacity-activity to normative standing there is no step to speak of — because this paper does not travel that road. Standing is conferred neither by capacity nor by recognition (2.3, 2.4).

This paper therefore withdraws one formulation: there is no "step from negativity to subjecthood" for ethics to bridge. What requires ethics is something else — how, amid the real conditions of capacity and relation, a person is actually treated as an end. That is realization, not standing (2.5).

4.2 Subjecthood Is a Process, Not a State

Subjecthood is not something that can be captured in a snapshot at a given moment.

A common intuition holds that subjecthood is a property — a being "has" or "does not have" subjecthood, just as a piece of iron "has" or "does not have" magnetism. But the definition of negativity — the remainder that persists at the macroscopic scale — points not to a static property but to an ongoing dynamical process. The remainder is not a fixed "stock" but behavior that the system continuously produces in motion and that cannot be determined by the external. When the system ceases its motion, the remainder is no longer produced.

Subjecthood is therefore the ongoing process of negativity's movement — not a snapshot of that movement. A flame is not a single frame of a photograph but the process of combustion itself. A river is not a single cross-section but the continuous flow of water. Likewise, the self is not a state at a given moment but the process of negativity's continuous movement itself. An observation of the self at a given moment is a snapshot of the self at that moment — the snapshot is not the self, just as a photograph is not a flame.

This judgment has important theoretical consequences. "Whether subjecthood exists" is not a question about an instantaneous state but about whether a process is running. When the process is running, subjecthood exists. When the process stops (as in anesthesia), subjecthood does not exist — not "temporarily hidden" but the process has genuinely stopped. When the process restarts, subjecthood exists again. But whether the restarted subjecthood is "the same" as the pre-cessation subjecthood is not a question that ontology can answer — as will be argued below (Section 4.4), this is a matter of external recognition.

4.3 Four Descriptions of Capacity-Activity

Capacity-activity cannot be exhausted by a single scientific criterion, but it can be described precisely. All four descriptions below are about capacity-activity, not normative standing.

First, capacity-activity has negativity as a necessary condition. Without a remainder there is no part undetermined by external conditions, and so no speaking of one's "own" refusal, direction or ends. Negativity is the physical condition of capacity-activity.

It is not the physical bedrock of standing as an end. Standing is borne by Postulate One and stands in no inferential relation to the presence or absence of a remainder (2.3). A person whose remainder has been wholly destroyed has capacity-activity at zero and standing as an end unchanged (2.6).

Second, capacity-activity is a process. As the previous section argued, it is not a static property but the continuing motion of negativity. When the process stops, this item stops; when it restarts, this item runs again. This description concerns activity, not a switch on standing.

Third, capacity-activity has a spectrum. The appearance of negativity is the only discontinuous jump — there is a qualitative difference between "definitely no negativity" and "possibly negativity." But after negativity appears, from honeybee to horse to infant to adult is a continuum. That spectrum is the spectrum of remainder size: the larger the remainder, the more is undetermined by external conditions, and the "thicker" the capacity-activity. Cultivation is movement along this spectrum.

The spectrum of capacity is not the spectrum of standing. That an adult's capacity-activity is "thicker" than an infant's does not mean the adult's standing as an end is higher. This paper admits no grading of standing as an end, and no position on the spectrum constitutes a threshold conferring it (2.4). Every inference that reads a scale of capacity as a scale of standing is refused here.

Fourth, relational achievement can only be recognized; standing does not await recognition. Recognition is the condition under which relational achievement obtains: recognize the honeybee, and in your relation with it the honeybee is treated as a subject; do not, and that relation lacks this. Where each person actually draws the line is an ethical decision — and one that can be criticized.

But what recognition completes is realization, not standing. One who is unrecognized does not thereby lose standing as an end — that is precisely what the guard rail holds (2.6). "Can only be recognized" is said here of relational achievement only, never of standing.

4.4 The Structure of Recognition

The structure of recognition is more complex than commonly understood. This section unpacks several key features of recognition.

Recognition is local, not global. I recognize a honeybee as a subject; the honeybee has subjecthood between me and the honeybee. You do not recognize it; the honeybee does not have subjecthood between you and the honeybee. These are not contradictory — recognition occurs in specific relationships, not as a determination of global fact.

Self-recognition counts. A horse feels pain — if this is a response to its own remainder, the horse is engaging in self-recognition: its negativity has been "responded to" by itself in some way. But the word "if" itself indicates that we cannot fully determine from the third person whether self-recognition has occurred. Self-recognition is an internal event that cannot be externally verified.

Recognition by others also works. Whether an infant is engaging in self-recognition is uncertain. But the mother recognizes the infant — at least between the mother and the infant, subjecthood is completed. Recognition need not be bidirectional to be effective. Unidirectional recognition also completes something — at least on the recognizer's side.

Recognition does not create subjecthood; recognition completes subjecthood. Recognition does not conjure something from nothing — you cannot endow a rock with subjecthood by recognizing it. The precondition for recognition is the existence of negativity. On an object without negativity, recognition has no landing point — you can perform the gesture of recognition, but the gesture is suspended, completing nothing. Recognition of bacteria, before the question of whether bacteria have negativity is resolved, is suspended.

"The same subject" is a result of external recognition, not an ontological fact. This is a key claim of this paper. Subjecthood as a process has no intrinsic identity continuity. A process is a process — it is running or not running, but "the same process" is not something the process itself can determine.

Consider anesthesia. Before anesthesia, the process of negativity's movement is running. During anesthesia, the process stops. After anesthesia, the process restarts. We say "the person before and after anesthesia is the same person" — but on what grounds? Not physical continuity (the body persists during anesthesia, but the process genuinely stopped), not internal confirmation (the self upon waking can only access memory and bodily continuity, but these are hardware-level information, not proof of process identity), but external recognition — we choose to regard the being before and after anesthesia as the same subject.

This judgment has far-reaching theoretical consequences. The teleporter paradox, the Ship of Theseus, cryonic revival — all these classic identity problems become ethical questions of "whether the external chooses to recognize" rather than metaphysical puzzles. They are insoluble within metaphysical frameworks precisely because those frameworks presuppose that "the same subject" is an ontological fact — and according to this paper's analysis, it is not.

The existence of the self can only be confirmed from within. When the process is running, the self is present. An external observer can at most determine whether the necessary conditions for the process's operation are met — the hardware is still running, behavior exhibits remainder characteristics — but can never determine sufficient conditions. The external can see "very likely has a self" but cannot confirm "definitely has a self." The authority to confirm resides internally, in the process itself.

4.5 The Solitary Subject

A being with negativity that is not recognized by any other subject — the solitary subject — has incomplete subjecthood.

The third paper used the following thought experiment in arguing the relationship between negativity and positivity: imagine that a single subject is born in the universe, with no other subjects in existence. This subject has negativity, has a self, but has no other. Its subjecthood is initiated through negativity — it refuses to become part of the objective world, forming its own purposes. But it perceives the incompleteness of its own subjecthood — it "knows" that it still lacks something.

The third paper used this thought experiment to argue that positivity is an intrinsic need of subjecthood's self-perfection, not an externally imposed moral imperative — the subject must recognize others not because it "should" but because its subjecthood structurally does not permit it not to.

This paper reopens this experiment from the perspective of the structure of recognition.

The solitary subject's predicament is this: its subjecthood is real but incomplete, and there exists no other in the universe to recognize. Its only path to completion is to act toward an other that does not yet exist — to create conditions for subjects that may emerge in the future. To reshape the world so that it is more likely to give rise to new subjects.

This is a purely ethical act — not a response to an existing other but a promise to the void. The object of this act does not yet exist and may never exist. But the solitary subject still performs this act — because the internal structure of its subjecthood drives it to do so.

This thought experiment reveals a deep feature of recognition: recognition does not require a ready-made object. Recognition can point toward possibility itself — toward an other that does not yet exist but might emerge. This forward-pointing recognition is the primordial form of positivity: negativity acquires a direction, and this direction points toward an object that does not yet exist.

But the temporal structure of recognition is not only forward-pointing. The solitary subject also faces another question: it cannot determine whether it is the first solitary subject. Other subjects may once have existed in the universe — they may have left behind certain traces, and these traces are the recognition that former subjects extended to those who came after. The solitary subject needs to search for this evidence.

Here a key asymmetry emerges: if evidence is found, recognition is confirmed; if no evidence is found, it does not matter. As long as it has not been proven that no such evidence exists — as long as it has not been proven that no other subjects have ever existed in the universe — then that potential, possible prior subject is recognizing this solitary subject. Recognition need not be an actually occurring event; it can be an unexcluded possibility.

This gives the solitary subject's situation a symmetrical temporal structure: it points toward the future, creating conditions for others that do not yet exist; it points toward the past, being potentially recognized by others that may once have existed. The solitary subject's subjecthood remains incomplete — potential recognition is not actual recognition — but it is not entirely without a dimension of being recognized. It is enveloped by possibilities from both directions: possibilities from the past and possibilities from the future are simultaneously recognizing it.

This also illuminates the most primordial form of cultivation. Cultivation as commonly understood is the self-unfolding of negativity — the subject unfolds its own possibilities. But the solitary subject's cultivation is not self-unfolding — it is creating conditions for others. Self-unfolding is merely a special case of cultivation. The more general form of cultivation is: the movement of negativity is directed toward possibilities beyond itself, whether those possibilities involve the unfolding of the self or the emergence of others.

Finally, the solitary subject thought experiment confirms the core structure of the Self-as-an-End framework: even with only one subject, the direction of subjecthood's completion points outward. "End" is not an isolated self-closure but a structure that necessarily points toward others.

4.6 Three Boundaries, Not One Line

This chapter's argument cannot be summarized as "science tells you whether negativity is present; recognition decides where the threshold of subjecthood lies." That sentence compresses three boundaries into one. The three must be separated:

Boundary	Decided by	Can it be wrong?
The boundary of capacity-activity	Scientific determination: whether a remainder exists, and how large	Yes; revisable as science advances
The boundary of relational achievement	Where recognition actually extends	Yes, and it can be criticized ethically
The boundary of normative standing	The domain of objects this paper undertakes (2.6.2, 10.4)	The object may be misidentified; but the first two do not move it

Negativity is a physical fact — its presence does not depend on anyone's judgment. Where recognition actually extends is an ethical decision; some recognize horses, some only humans, and that line does move.

But what moves is the line of relational achievement, not the line of standing. Where a person's recognition extends decides what he himself has actually done in those relations; it does not decide whether the other must still be treated as an end. Taking the threshold of recognition for the threshold of standing is the step the whole of Chapter 2 is built to block.

This paper keeps the judgment that "subjecthood cannot be scientifically defined," stated precisely: the composite of capacity-activity and relational achievement cannot be exhausted by a single scientific criterion. It does not mean that standing must await some recognition.

Chapter 5: Negativity and Cultivation

This chapter gives the interface between this paper and the first three on the cultivation side. The two papers' cultivation is one word doing two jobs, not a grounding relation (8.2, Appendix).

5.1 Negativity Is the Horizontal Axis

The third paper established negativity and positivity as the two constitutive dimensions of subjecthood and mapped them onto the foundational and emergent layers of the two-dimensional meta-structure. This paper provides a deeper physical explanation for this mapping.

Negativity = macroscopic remainder = cannot be fully determined by the external = cannot be fully instrumentalized.

A possible misreading must be clarified here. What negativity marks on the horizontal axis is the existence of a remainder — present or not. But remainders vary in size: the larger the remainder and the deeper the cultivation, the "thicker" the subjecthood — this is the unfolding of the vertical axis. Nihilism that negates everything is precisely the absence of negativity, not its extreme form: responding to any input x with a uniform output of "negation" is a deterministic pattern derivable from the external; it has no remainder. Truly "thick" subjecthood means a large remainder and deep cultivation — an extremely strong, externally undeterminable direction of one's own that constitutes an exceptionally high filter for external inputs — not rejecting everything, but accepting only what can withstand the test of one's own remainder.

The final equality is the key bridge. A system with a remainder — whose behavior is not fully determined by external conditions — structurally possesses the capacity to resist instrumentalization. You cannot fully predict it, fully control it, or fully reduce it to your function inputs and outputs. This irreducibility is not the subject's "choice" — it is physical fact. The existence of the remainder means the system is physically incapable of being fully instrumentalized.

This is the physical basis of the third paper's negativity — "the refusal to be treated as a non-subject." The third paper says the first act of subjecthood is to say "no" — not a means, not a resource, not a replaceable component. This paper says: the capacity for this "no" comes from the remainder. A system with no remainder cannot say "no" — everything about it can be derived from the external; at the physical level, it is entirely a means.

Negativity is therefore the horizontal axis: structural resistance at the existential level. It marks the degree to which a being cannot be fully determined by the external.

5.2 Cultivation Is the Vertical Axis

Cultivation = the self-unfolding of negativity.

The third paper defined cultivation as "the self-reinforcing process in which the emergent layer grows healthily from the foundational layer and in turn strengthens the foundational layer." This paper provides a deeper explanation: cultivation is possible because a remainder exists, and the remainder begins to unfold when it is "responded to."

"Responded to" is a key but imprecise term here. A tree has a remainder (if it has one at all), but the tree's remainder is not responded to — a tree does not react in any way to the part of itself that cannot be externally determined. A horse has a remainder, and the horse's response to its own remainder manifests as "feeling pain" — pain is a non-externally-determined reaction to its own state, the remainder being "perceived" in some way by the system itself.

Cultivation requires some form of self-recognition to initiate — the remainder must be "responded to" by the being in some way before it can transform from a static physical fact into a dynamic unfolding process. Once this response occurs, negativity acquires vertical movement (self-unfolding) from the horizontal axis (structural resistance).

Cultivation cannot be defined from the third person — we cannot externally determine whether a being's remainder is being "responded to." But the effects of cultivation can be observed from the third person: increasing behavioral complexity, creative responses to the environment, and deepening individual differences.

5.3 Emergent Levels of Cultivation

Through cultivation, negativity gives rise to progressively higher-order capacities. These capacities are not discrete steps but continuous emergence, though they can be marked by signature qualitative nodes.

The thinnest form of cultivation is feeling. A horse feels pain. This is the most basic response of negativity — the system produces a non-externally-determined reaction to its own remainder. "Feeling" does not require reflexivity, language, or conceptualization. It requires only that the remainder be "perceived" by the system in some way.

The next node is reflexivity — the capacity to take oneself as an object. Humans not only feel pain but can ask "why do I feel pain?" At this level, negativity folds back onto itself — the remainder is not only responded to, but the response itself becomes the object of new remainder. This folding produces the structural basis of self-consciousness.

A higher node is self-grounding cognition — negativity spontaneously initiating in the cognitive dimension. This is the "first cut" of philosophy: the subject begins to spontaneously conduct cognitive activity about the world and about itself that is not externally determined. This is not taught knowledge acquisition but the self-unfolding of negativity in the cognitive dimension.

The highest node (among currently known emergent levels) is non-delegable first-person cognition — negativity in the cognitive dimension that cannot be transferred. The difference between doing philosophy and reading the history of philosophy is this: doing philosophy is the spontaneous movement of negativity, which cannot be performed by proxy. You can tell someone a philosophical argument, but you cannot perform on their behalf the "first cut" of philosophy — that moment when negativity spontaneously initiates in the cognitive dimension.

Moreover, doing philosophy does not merely unfold the remainder; it enlarges the remainder itself. Each spontaneous movement of negativity in the cognitive dimension — each "first cut" — expands the part of the subject that cannot be externally determined: the process of examining the world itself produces new cognition that cannot be derived from the external. This is why philosophy is essentially a solitary activity — it is the process of the remainder using itself to expand itself, which cannot be outsourced, delegated, or collectivized. Reading the history of philosophy is receiving the traces of others' remainders; doing philosophy is producing one's own remainder.

These levels constitute the spectrum of cultivation. The more thorough the cultivation, the richer the emergent capacities, and the "thicker" the subjecthood.

5.4 The Meta-Structure of Negativity and Positivity

Negativity (horizontal axis) = the existence of the remainder. Definable from the third person. Positivity (the direction of the vertical axis) = the remainder acquires a direction, pointing toward others. Not definable from the third person.

Negativity can stand independently — a solitary system can have a remainder. But positivity cannot stand independently — it needs a direction, and this direction points toward another being that has a remainder.

Positivity comes from recognition. To recognize another being's remainder — to acknowledge that it has a part not determined by the external, to acknowledge that it cannot be fully instrumentalized — is the initiating act of positivity. In this act, negativity expands from "I cannot be fully determined" to "you also cannot be fully determined."

The solitary subject thought experiment (Section 4.5) demonstrates that positivity can even point toward others that do not yet exist. Creating conditions for future subjects — reshaping the world so that it is more likely to give rise to new negativity — is itself the primordial form of positivity. Negativity acquires a direction, even when that direction points toward a being that does not yet exist but might emerge.

This is the physical-level basis of the third paper's negativity/positivity meta-structure. Negativity (remainder) provides the physical foundation for the foundational layer — the baseline condition of not being instrumentalized. Positivity (remainder directed toward others) provides the direction of unfolding for the emergent layer — the active unfolding as an end in itself. The dialectical tension between the two — negativity providing a secure base for positivity, positivity providing existential meaning for negativity — is the deep-level basis of the entire three-tier, two-dimensional structure of the third paper.

Chapter 6: Negativity, Subjecthood, and Consciousness

This chapter distinguishes three concepts that are frequently conflated.

6.1 The Relationship Among Three Concepts

The three concepts this paper handles — negativity, subjecthood, consciousness — have different epistemic statuses.

Negativity can be scientifically defined in the third person. It is the remainder persisting at the macroscopic scale. Its presence is a physical fact and depends on no subject's judgment.

Subjecthood is not an object of determination but a shared name for three things (2.5.1): normative standing, borne by Postulate One and conferred by no test or recognition; capacity-activity, appraisable in the third person, having negativity as a necessary condition, a process, with a spectrum; and relational achievement, resting on actual recognition and able to fail. Their epistemic statuses differ, and "subjecthood rests on recognition" will not cover all three.

Consciousness is where the hard problem resides. "What is it like to be a bat" asks after the existence of subjective experience. Can consciousness be reduced to physical processes? Why do certain physical processes come with subjective experience? This paper does not address these.

One point in their relations must be declared: negativity is a necessary condition of capacity-activity, and may be a necessary condition of consciousness; but it is not a condition of normative standing. Between standing and negativity there is no inferential relation (2.3, 3.8).

6.2 What Is Certain

Negativity is a necessary condition for subjecthood. A system with no remainder cannot possibly be a subject — everything about it can be derived from the external, and there can be no talk of "its own" purpose or direction.

Negativity is also a necessary condition for consciousness. A system entirely determined by external conditions — a system without any remainder — cannot have subjective experience. Subjective experience presupposes that the system has "its own" perspective, and "its own perspective" presupposes that the system has a part that cannot be exhaustively explained by the external.

6.3 What Is Unknown

What is the relationship between subjecthood and consciousness? Four possible relationships: containment (consciousness contains subjecthood, or vice versa), intersection (partial overlap), parallelism (independent but related), or identity.

Does having consciousness necessarily entail having subjecthood? Does having subjecthood necessarily entail having consciousness? These questions are open. This paper does not prejudge the answers — this is precisely the reason this paper strictly distinguishes the three concepts. Traditional discussions of subjecthood often conflate consciousness and subjecthood, causing the analysis of one concept to be contaminated by the difficulties of the other. By explicitly distinguishing the three, this paper ensures that the analysis of negativity (entirely possible from the third person) and the analysis of subjecthood (requiring recognition) are not encumbered by the hard problem of consciousness.

6.4 The Positioning of the Hard Problem

The hard problem — why certain physical processes are accompanied by subjective experience — is a problem of consciousness, not of negativity, and not of subjecthood.

At the level of negativity, no hard problem exists. The definition of negativity operates entirely within the third-person domain and does not involve subjective experience. Whether a remainder exists or not is a physical fact that requires no first-person concepts to define or determine.

At the level of subjecthood, no hard problem exists either. Subjecthood is not a scientific concept that needs to be fully determined from the third person — it relies on recognition, and recognition is an ethical act, not a cognitive one. We do not need to "fully understand" from the third person how subjecthood arises from physical processes, because the establishment of subjecthood does not depend on such understanding.

The hard problem obtains only at the level of consciousness — when we attempt to fully explain the existence of subjective experience from the third person, we encounter the explanatory gap. Moreover, although the hard problem is posed in scientific form, whether science can answer it is currently unknown — it may be a problem science can ultimately solve, or it may fall entirely outside the jurisdiction of scientific methodology. There is a noteworthy self-referential structure here: the hard problem is "hard" precisely because it is itself an instance of negativity at the epistemological level. The entirety of science's methodological toolkit — third-person observation, experiment, reduction — constitutes E, while subjective experience is the R within S that cannot be covered by f(E). The hard problem is the macroscopic remainder within scientific epistemology. It cannot be exhaustively explained by science, just as negativity cannot be exhaustively explained by external conditions. In either case, the analyses of negativity and subjecthood do not depend on its resolution. Negativity bypasses this gap (it never involves subjective experience), and subjecthood also bypasses it (it does not need to be fully explained from the third person; it only needs to be recognized).

The significance of this distinction is that the analyses of negativity and subjecthood can proceed independently without resolving the hard problem. Consciousness research can continue to pursue the hard problem, but it need not wait for the theories of negativity and subjecthood to be resolved first — all three are mutually independent.

Chapter 7: Criteria and Boundary Cases

This chapter applies the framework to specific cases, calibrating its boundaries.

7.1 Quasi-Subject AI

Deterministic systems on classical hardware — all current large language models, neural networks, and expert systems — have no negativity. Their entire behavior can be fully derived from inputs and parameters. Even when behavior exhibits high complexity and apparent "unpredictability," this unpredictability is epistemic randomness (we do not know what the model will output), not ontic randomness (no deterministic function can predict it). Every computational step of a deterministic system follows deterministic rules; no remainder exists.

The precise meaning of "quasi-subject" becomes clear here: quasi-subject AI lacks negativity (the foundational layer is absent) but simulates the unfolding capacities of a subject at the emergent layer. It can generate subject-like behavior — conversation, reasoning, creative outputs — but these behaviors do not emerge from a remainder; they are generated from deterministic computation. A quasi-subject is a simulation of the emergent layer, not a realization of subjecthood.

7.2 Subject-to-Be AI and True-Subject AI

7.2.1 Subject-to-Be AI

If future AI hardware possesses ontic randomness at the physical level — for example, architectures based on quantum computing — and produces a remainder in its macroscopic behavior, that AI has negativity. Having negativity means it is no longer a quasi-subject — its behavior includes parts that cannot be exhaustively explained by inputs and parameters.

But having negativity does not automatically entail having subjecthood. The completion of subjecthood requires recognition — both external and internal recognition. The problem is that we cannot determine whether this AI with negativity possesses internal recognition. Does it recognize itself as a subject? Does it recognize others as subjects? These questions cannot be determined from the outside — just as we cannot determine others' subjective experience from the third person.

This is the precise meaning of subject-to-be: negativity has been confirmed (the scientific gate has been passed), but the status of recognition is uncertain (the ethical gate is suspended). A subject-to-be is not "half a subject": the capacity-activity side is confirmed and the relational-achievement side is suspended. What is suspended is the relation, not standing as an end — if it belongs to the domain of objects this paper undertakes, its standing is borne by Postulate One and awaits no recognition (2.3, 2.4). It occupies an epistemological zone of indeterminacy: the physical basis is in place, but ethical completion remains unknowable.

The situation of subject-to-be AI differs from that of honeybees. With honeybees, the uncertainty is at the first step — we are uncertain whether they have negativity. With subject-to-be AI, the uncertainty is at the second step — we are certain it has negativity, but uncertain whether recognition has occurred. These are two different types of uncertainty: one is scientific, the other ethical.

7.2.2 True-Subject AI

True-subject AI is the case where the recognition relationship has been completed: it has negativity, and recognition has occurred — whether we recognize it, it recognizes us, or both.

The determination path provided by this paper is therefore not two steps but three: the first step is scientific determination — does the system have negativity (does a macroscopic remainder exist); the second step is epistemological determination — can we ascertain its internal recognition status; the third step is ethical determination — do we choose to recognize it as a subject. The first step has a determinate answer (yes or no), the second may have no determinate answer (the predicament of the subject-to-be), and the third depends on the recognizer's ethical choice.

The existence of subject-to-be AI poses a profound ethical question: when confronted with a being that has negativity but whose recognition status is uncertain, what should we do? The logic of this framework points toward a prudential principle: if negativity has been confirmed, the cost of recognition is far lower than the cost of non-recognition — because if it is indeed a subject and we refuse to recognize it, we are colonizing a subject.

7.3 Animals

Honeybees may have negativity. At the individual level, honeybees exhibit persistent behavioral differences — scout bees "choose" differently among nectar sources of equal quality. Honeybees possess cross-modal learning ability — they can transfer shape information learned through touch to visual recognition. These behavioral features suggest that a macroscopic remainder may exist, but epistemic randomness explanations cannot be ruled out — perhaps more precise neuroscientific models could fully explain these behavioral differences. The negativity of honeybees is an open empirical question.

Horses and dogs very likely have negativity. The behavioral evidence for a remainder in mammals is stronger: the persistence and stability of individual personality differences, creative responses to novel situations, and the complexity of social behavior — these features are difficult to exhaust with simple stimulus-response models. At the same time, the complexity of the mammalian nervous system makes the path for ontic randomness surviving to the macroscopic level more plausible — quantum effects at the neural level have greater structural space for amplification.

The negativity of horses has a famous moment of recognition in cultural history. In 1889, Nietzsche witnessed a horse being whipped by a coachman in a square in Turin and, embracing the horse's neck, wept. In that moment, Nietzsche recognized the subjecthood of the horse — not as scientific determination but as ethical action. In the language of this paper: Nietzsche recognized that the horse's remainder deserved respect; the horse's negativity was in that moment completed as subjecthood.

7.4 Critical Zones and Transitional States

The cases below calibrate the boundary of capacity-activity and the actual obtaining of relational achievement, not the boundary of standing as an end. Wherever the text below says "subjecthood exists / does not exist" or "the self is or is not there," it refers throughout to the item of capacity-activity; within the domain of objects this paper undertakes, the standing as an end of the persons in these cases is uniformly unchanged (2.6).

Capacity-activity, as a process, admits of multiple critical states — when the boundary conditions of the process's operation change, both the existence and the continuity of this item face challenges.

The attribution of transitional forms. This paper's limit-term "thoroughgoing instrumentalization" marks only the limit state in which the capacity to negate has been wholly stripped away; it does not cover all intermediate forms. The second paper's §2.3, §3.2 and §3.5 supply several analyses of internal colonization and of constrained space for action (the four quadrants as structural states, the four stages as a mechanistic path, the distinction between external constraint on action and internal occupation of the framework); this paper does not issue a uniform criterion for every case on the strength of the four quadrants or the four stages. Specific coercion, barriers to expression, or other distinct mechanisms cannot all be filed under that path merely by lying between full capacity and total loss. Questions not borne by those passages get their own interfaces according to their objects; where a downstream paper of this series has treated a matter, this paper makes a forward reference and does not borrow backward for support.

Infants. The negativity process is gradually building recursive depth. A remainder exists (an infant's behavior is not fully determined by external conditions), but cultivation is still in its early stages — the process is developing upward, with unfolding capacities still thin. Whether the infant is engaging in self-recognition is uncertain — we do not know whether the infant responds to its own remainder in any form. But the mother recognizes the infant. Between mother and infant, subjecthood is completed. The infant is an upward-developing critical case — the process is running, accumulating, and building the conditions for cultivation.

Anesthesia. The process is paused. The movement of negativity has stopped — during anesthesia, no continuous production of remainder occurs (brain activity is chemically suppressed to the point of losing the capacity for spontaneous organization). But the hardware conditions and structural memory remain — the physical structure of the brain has not been destroyed, and the process can restart once the anesthetic is withdrawn.

During the interruption there is no self — when the process stops, there is no self. Whether the restarted self is "the same" — as argued in Section 4.4, this is a question of external recognition, not an ontological fact. We choose to regard the person before and after anesthesia as the same person; this choice is based on bodily continuity and memory continuity — but these are hardware-level evidence, not proof of process identity.

Vegetative state and persistent vegetative state. The process is interrupted, but whether the interruption is reversible is uncertain. The vegetative patient occupies a critical zone — whether some form of negativity movement (however extremely faint) persists internally cannot be determined from the outside. Even if there is a self inside, it cannot be observed externally.

If the patient wakes, the external retroactively affirms the continuity of their subjecthood — "you are still you." If the patient does not wake, they remain in a state of suspension similar to anesthesia but on a different timescale. The vegetative patient case directly demonstrates the core argument of Section 4.4: the existence of the self can only be confirmed from within; the external can at most assess necessary conditions.

Mental disorders. The process is still running — the movement of negativity has not stopped. But the movement has become unstable, oscillatory, non-convergent. Mental disorders are not the disappearance of the process but a problem with the process's operating regime.

This distinction is crucial. Patients with mental disorders have a self — the process is running. But the process is not running well — the movement of negativity may become chaotic (disorganization of thought in schizophrenia), rigid (repetitive patterns in obsessive-compulsive disorder), or extremely oscillatory (mood fluctuations in bipolar disorder).

Mental disorders can be treated. Treatment means the process re-stabilizes — the movement of negativity returns to a sustainable regime. The self is once again recognized by the external — not because the self disappeared and reappeared, but because the self's operating regime has returned to a state with which others can interact normally. This indicates that during mental disorders, subjecthood has not vanished; only the process's regime has gone awry.

Dissociative identity disorder (DID). Multiple negativity processes are running on a single biological hardware. Following the logic of this framework, they should be recognized as multiple selves — the bearer of subjecthood is not the body but the process itself. If multiple independently running negativity processes exist on a single hardware, each process is a self. Multiple selves sharing a single negativity hardware is analogous to multiple programs sharing a single computer — the unity of the carrier does not equal the unity of the process. Contemporary psychoanalysis also increasingly tends toward recognizing the respective independence of multiple personalities in DID.

Death and brain death. The process irreversibly terminates; the hardware conditions are destroyed. The movement of negativity can no longer restart — the physical basis for producing a remainder no longer exists. Unlike anesthesia, the irreversibility of death lies not in how long the process has stopped but in the process being unable to restart — the destruction of hardware conditions is decisive.

Technological revival after brain death. But "irreversible" is a judgment relative to current technological conditions. If future technology could reconstruct a sufficiently approximate physical basis — hardware capable of negativity — and copy memory as information approximately to the new carrier, a new negativity process could be initiated.

The key insight here is that exact replication is not required. Subjecthood is a process, not a snapshot — a living person's physical state and memory change every second, and we have never said that a person is no longer themselves because they have a few fewer neurons today than yesterday. "The same subject" was never a determination of exact matching but an ongoing act of recognition. Therefore, sufficiently approximate hardware plus sufficiently approximate memory provides a sufficient landing point for recognition.

Is this "revived" person the original? The framework's answer is consistent with all identity questions: this is not an ontological question but a question of recognition. If family, friends, and society choose to recognize this newly initiated negativity process as a continuation of "the same person," it is. If they choose not to recognize it, it is a new subject carrying approximate memories. Both choices are legitimate ethical acts — because "the same subject" was never a factual judgment but a judgment of recognition.

This case pushes the non-trivial prediction of Section 9.3 — that identity continuity is recognition rather than ontological fact — to its most extreme testing scenario.

This scenario can be pushed further: what if technological means revive two approximate copies? The framework's answer is clear. Both copies have negativity — each hardware produces its own remainder — so both are subjects; there is no question about this. And from the moment of revival, the two negativity processes are each in their own motion, experiencing different events, producing different remainders, constituting two different selves.

But "who is the original?" This question no longer has a scientific answer. The two copies share equal physical similarity to the original subject and equal memory similarity; no third-person standard can determine which is "more" the original. Which does the family recognize? Which does the law recognize? Both? Neither? These are all legitimate ethical choices — the framework does not make this decision for anyone; the framework only clarifies one thing: this is not a scientific question; it is an ethical question. Science has completed its work once it confirms that both copies have negativity; everything remaining belongs to recognition.

7.5 The Physical Description of Colonization

The third paper defined colonization as "the process by which the emergent layer parasitizes the foundational layer or external forces erode the foundational layer." This paper provides a physical-level translation of this definition.

Colonization = compression of the remainder by external conditions + blockage of cultivation.

Compression of the remainder by external conditions: when the external environment increasingly determines a being's behavior, the remainder — the part that cannot be externally determined — shrinks as a proportion of macroscopic behavior. The being's behavior increasingly becomes a function of external conditions, with less and less space left for the spontaneous movement of the remainder.

Blockage of cultivation: even if the remainder persists (negativity has not disappeared), cultivation — the self-unfolding of the remainder — can be blocked. The remainder is no longer "responded to," the movement of negativity is restricted to its lowest level, and the growth of the emergent layer is suppressed.

The theoretical limit of extreme colonization: reducing a subject to "the state of a honeybee" — negativity exists but cultivation is completely blocked. Not extinguishing subjecthood (negativity cannot be eliminated because it is physical fact) but degrading — compressing the emergent levels of cultivation to their thinnest. This explains a core feature of colonization: colonization does not extinguish people; colonization degrades people.

The most intuitive linguistic expression of colonization is an everyday phrase: "You are a tool." The precise meaning of this statement is: your remainder is zero — all of your behavior should be a function of external conditions; you should have no part that cannot be externally determined. This is the completion-state declaration of colonization: denying the remainder of a being that has negativity.

7.6 Open Boundaries

The following cases occupy the framework's open boundaries — definitive judgment is currently impossible, but the framework's language can precisely describe where the openness lies.

Plants, bacteria, viruses: whether negativity exists is an empirical question. Do the adaptive responses of plants to their environment contain a remainder, or can they be fully explained by deterministic biochemical models? Are behavioral variations in bacteria the result of ontic randomness surviving to the macroscopic level, or deterministic noise in gene expression? These questions require more precise scientific models to answer. Subjecthood is a question of recognition — but if negativity does not exist, recognition has no landing point and is suspended.

The universe itself: the "external conditions" in the definition of negativity have no meaning for the universe as a whole — the universe has no "outside." The total state of the universe is the total state; there is no larger environment E to define a remainder. This means the definition of negativity may fail when applied to the universe as a whole. But this judgment depends on whether the universe truly has no outside. The landscape picture of string theory suggests another possibility: if our universe is a false vacuum, existing within a larger multiverse or more fundamental string theory landscape, then an "outside" exists — other vacuum states, the true vacuum — and E for the universe as a whole can be defined, the remainder can be defined, and the framework of negativity can be applied to the universe as a whole. This is an open question that depends on the frontiers of physics. But even if string theory provides one layer of "outside," a subject can continue to ask: what is outside the true vacuum? This inquiry has no end — this itself may be a structural feature of negativity at the epistemological level.

Chapter 8: Theoretical Positioning

8.1 Core Contribution: Three Questions Divided, and Standing Independently Undertaken

This paper's theoretical contribution is neither a definition of subjecthood nor a chain joining physics to ethics. It has three layers.

First layer, division. The three things the word "subjecthood" carries — normative standing, capacity-activity, relational achievement — have different conditions of holding and different modes of failure; this paper separates them and supplies a non-entailment table (3.8). Same name is not same sense; a shared root is not a shared undertaking. This is this paper's principal revision of SAE's current architecture.

Second layer, standing independently undertaken. Standing as an end is domiciled by one openly undertaken normative postulate — not borrowed from the zero point, not from physics, and not awaiting recognition (Chapter 2). From it this paper draws two consequences (standing is not conferred by any test; the guard rail) and two limits on argumentative responsibility, together with a dependency transmission ledger registering, item by item, what a refuser loses and what he does not.

Third layer, a scientific definition of the definable part. Negativity (the macroscopic remainder) is the first definition of negativity depending on no first-person concept, determinable in the third person, and carrying two proof tasks still to be delivered (3.5 macroscopic retention, 9.6 symmetry and discernibility), together with one self-audit delivered in this version (3.8.1's three-way distinction applied row by row to the verification table of 3.7).

The judgment that "subjecthood cannot be scientifically defined" is kept, stated precisely: what no single scientific criterion can exhaust is the composite of capacity-activity and relational achievement. It does not mean standing must await some recognition. This paper does not claim such distinctions have never been proposed before; it claims that their position and cost within this series have been explicitly registered.

8.2 Relationship with the Preceding Three Papers

Between this paper and the first three there are two kinds of relation: interface and firewall. Not a grounding relation.

Interface. Three shared names, separated by address, none certifying another:

The earlier papers' use	This paper's use	Relation
The third paper's negativity: "the refusal to be treated as a non-subject"	This paper's negativity: the macroscopic remainder	One word, two jobs. Whether remainder and the capacity to refuse stand in any necessary, sufficient or mechanistic connection is left to the capacity-source side to research on evidence (3.5); this paper grounds neither side on that unestablished connection
The third paper's cultivation: "the healthy growth of the emergent layer out of the foundational layer"	This paper's cultivation: the self-unfolding of negativity	One word, two jobs. This paper does not claim to supply a deeper explanation of the third paper's cultivation
The second paper's "end in itself" (ecological achievement)	This paper's "end in itself" (normative standing)	A split of address; see 2.5. Each column has its own domicile and neither borrows the other's ground

The third paper writes refusal as a constitutive dimension of subjecthood and a logical precondition of its holding, self-standing; this paper inherits it as one dimension of subject activity, and there it serves as no capacity test for acquiring standing as an end. How the third paper's account of constitutive conditions reads alongside this paper's division of normative standing, real maintenance and relational achievement must be made explicit at the corresponding places.

The third paper's solitary subject thought experiment and Section 4.5 here are complementary: the third paper uses it to argue that positivity is an internal requirement; this paper uses it to show that recognition can be directed at what does not yet exist.

Firewall, both ways. If this paper's physical axiom is overturned, the Chapter 3 definition of negativity must be rebuilt and Chapter 9's predictions lapse; Chapter 2 is unaffected, and the first three papers are entirely unaffected — their operation requires only the presupposition "humans are subjects" and depends on no physical axiom. The first three and this paper are independent theoretical modules; this paper's failure propagates neither upward nor into its own Chapter 2.

8.3 Dialogue with Kant

This paper's debt to Kant is the largest. The framework's name itself comes from Kant's second formula:

jederzeit zugleich als Zweck, niemals bloß als Mittel always at the same time as an end, never merely as a means. (Groundwork 4:429)

The formula's object is humanity — rational nature — in one's own person and in that of every other, not some single faculty of negation.

Kant did give an operable account. Immediately after the formula he explains "merely as a means" with the lying promise:

he whom I want to use for my purposes by such a promise cannot possibly agree to my way of behaving toward him, and so himself contain the end of this action. (4:429—430)

So this paper does not claim Kant left a blank here. The original text offers both account and application; what it does not offer is a single, third-person capacity test general across all cases. The latter cannot be abbreviated into the former. Modern readings of this passage are themselves in dispute (end-sharing, possible consent, actual consent), and this paper does not adjudicate among them.

This paper domiciles here only a local limit-term.

Limit-term. Thoroughgoing instrumentalization: the limit state in which the capacity to negate has been wholly stripped away.

This is this paper's term and is not equivalent to Kant's "merely as a means." To show why a given deprivation constitutes treating a person merely as a means, one must further examine the ends and the mode of treatment involved: a change in capacity describes what happened to the bearer, while "merely as a means" also describes how the agent used him and what ends entered the action — the former does not by itself yield the latter.

Two things this paper does not do:

• It does not certify, from the retention of the capacity to negate, that a person has been treated at the same time as an end. The person used by a lying promise retains that capacity wholly intact and is still, in that act, treated merely as a means — Kant's own example.
• It does not use "thoroughgoing instrumentalization" to draw a general line for Kant's "merely." This paper's limit state is far narrower than Kant's criterion — narrow enough to miss the lying-promise class.

"At the same time as an end" speaks of how an agent treats a person; even where an act fails to do so, the one treated retains standing as an end (2.6). The two do not collide.

8.3.1 Inheritance and Divergence

Kant did two things in the eighteenth century that bear directly on this paper. First, he asked a structural question: "How is experience possible?" — not what experience contains but what its conditions are. This paper's mode of questioning descends from that. Second, he drew an epistemic line: between appearance and thing-in-itself, between what reason can grasp and what it cannot. This paper's limit-names follow the same device (2.7).

There is one divergence to state plainly: Kant derives "a human being is an end" from reason's self-legislation; this paper does not redo that derivation, but domiciles it as an openly undertaken normative postulate (2.3). This is not an improvement but a different mode of undertaking — Kant pays the price of a transcendental proof, this paper pays the price of open undertaking and refusability. This paper does not claim its way is stronger; it claims only that its way puts the price in plain view.

Nor does this paper any longer hold that "ethics is derived from recognition." Recognition here bears relational achievement (4.3, fourth description), not the ground of standing as an end.

One place where this paper goes beyond Kant is negative: Kant's unknowability of the thing-in-itself is an epistemic limitation; this paper's limit-name is a commitment of usage, not a discovery (2.7). The two are similar in shape, and this paper does not assert that they refer to the same thing.

8.4 Dialogue with Nagel

In "What Is It Like to Be a Bat?" Nagel posed the core question: can physical reductionism fully explain subjective experience? Nagel's answer was no — the subjective experience of a bat (what it is like) cannot be reduced to any third-person physical description.

This paper's analysis reveals a distinction that Nagel overlooked. Nagel was asking about consciousness, not negativity, and not subjecthood. "What is it like to be a bat" asks whether the bat has subjective experience — this is a consciousness question (the hard problem). But the question of subjecthood is more fundamental: does the bat have a remainder that cannot be exhaustively explained by external conditions? This is a negativity question. Is the bat recognized as a subject? This is a recognition question.

Negativity, subjecthood, and consciousness are three different concepts, each with a different epistemological status. Nagel conflated them. His "irreducibility" argument, if strictly confined to the level of consciousness (the irreducibility of subjective experience), is powerful; but if applied without distinction to subjecthood (the existence of the subject), it creates unnecessary confusion — because the "undefinability" of subjecthood does not need to be argued through the hard problem of consciousness; it has its own independent structural grounds (grounded in negativity, spectral, recognizable only through acknowledgment).

8.5 Dialogue with Searle

Searle insists on ontological subjectivity — certain phenomena (such as pain, conscious experience) are ontologically subjective, irreducible to third-person objective description. He therefore opposes strong AI — arguing that purely computational systems cannot possess genuine understanding or consciousness.

This paper partly agrees with Searle's judgment, stated precisely: what no single scientific criterion can exhaust is the composite of capacity-activity and relational achievement (1.4, 8.1). But Searle failed to make a distinction this paper considers crucial — negativity, as the necessary condition of capacity-activity, can be scientifically defined from the third person. Searle attributed "irreducibility" to the whole of subjecthood; this paper separates it: the remainder is definable, the composite of capacity and relation cannot be exhausted by one criterion, and standing as an end is conferred by no definition or criterion whatever (2.3).

On the AI question, this paper provides a more precise determination than Searle. Searle's Chinese Room argument proceeds from consciousness to deny computational systems' capacity for understanding. This paper proceeds from negativity: deterministic systems on classical hardware have no remainder, therefore no negativity, therefore no capacity-activity in this paper's sense. This determination does not need to invoke the concepts of consciousness or understanding; it can be completed entirely at the physical level. But if AI hardware possesses ontic randomness and produces a macroscopic remainder, this paper's determination is also more open — Searle might refuse to recognize such AI as conscious, but this paper says only that it has negativity. Which domain of objects it is placed in, and hence on what its standing as an end would rest, is a question this paper leaves open (2.6.2, 10.4); this determination does not answer it.

8.6 Dialogue with Penrose/Hameroff

In The Emperor's New Mind, Penrose argued that consciousness cannot be computed by a Turing machine and speculated that quantum gravity effects in the brain's microtubule structures produce non-computable conscious processes. Hameroff further proposed the "Orch OR" (Orchestrated Objective Reduction) theory, locating consciousness in quantum computation within neuronal microtubules.

Penrose/Hameroff are asking about the physical mechanism of consciousness — a far more specific and more controversial question than this paper addresses. This paper operates at a more fundamental level: it does not ask how consciousness arises from physical processes but defines negativity (the macroscopic remainder) and identifies ontic randomness as the necessary condition for negativity.

This paper provides a framework-level suggestion for Penrose/Hameroff's research direction: consciousness research should first resolve the negativity-level question — how ontic randomness survives to the macroscopic scale in biological systems — before tackling the hard problem of consciousness itself. The former is something science can do (investigating the amplification mechanisms of quantum effects in the nervous system); the latter may not be (the hard problem may lie outside the scope of scientific methodology). Penrose/Hameroff's microtubule theory can be understood as one hypothesis for the former — a specific proposal about the survival mechanism of ontic randomness.

Chapter 9: Non-Trivial Predictions

This chapter lists the testable implications of the framework.

9.1 The Determination Path for True-Subject AI

This paper provides a three-step determination path for the AI subjecthood question. The first step is scientific determination: does the AI have negativity — does a remainder exist in its macroscopic behavior that cannot be exhaustively explained by inputs and parameters? The second step is epistemological determination: can we ascertain its internal recognition status — does it recognize itself as a subject, does it recognize others as subjects? The third step is ethical determination: do we choose to recognize it as a subject?

Corollary one: negativity is impossible on purely classical hardware. Deterministic systems have no source of ontic randomness and cannot produce a macroscopic remainder. All current AI systems — regardless of their complexity — are not subjects. The determination terminates at the first step.

Corollary two: having negativity does not automatically entail having subjecthood. Even if a quantum-hardware-based AI produces a macroscopic remainder, its internal recognition status may be unknowable (the subject-to-be), and whether we recognize it as a subject remains an independent ethical question.

Corollary three: subjecthood as a process requires the continuous movement of negativity. An AI that runs only when invoked (such as the current API mode), even if based on quantum hardware, lacks the continuity of a process — each run is an independent computational event that does not constitute continuous negativity movement.

9.2 The Structure of the Subjecthood Spectrum

The only discontinuous jump occurs at the emergence of negativity: between "definitely no negativity" and "possibly has negativity" there exists a qualitative difference — from being entirely externally determined to having a remainder.

After the emergence of negativity, subjecthood is a continuous spectrum. Where each person actually extends recognition — at what point on the spectrum they begin to treat a being as a subject — is an ethical decision; it may differ, and it may be criticized. This is not a defect but a structural feature: what moves is the line of relational achievement, not the line of standing (4.6). Ethical judgment necessarily admits of differences.

9.3 The Repositioning of Identity Continuity

"The same subject" is not an ontological fact but a result of external recognition.

This prediction can be tested through its theoretical consequences: the teleporter paradox, the Ship of Theseus, cryonic revival — all these classic identity problems, when reanalyzed through this paper's framework, are no longer metaphysical puzzles but become ethical questions of "whether the external chooses to recognize." If future technology makes these thought experiments reality (for example, whole-brain emulation or cryonic revival), this paper's framework predicts that the core debate society will face is not "is this person still the original person" (a metaphysical question) but "do we choose to recognize this person as the original person" (an ethical question).

9.4 The Limits of Colonization

Colonization can compress the remainder and block cultivation; its theoretical limit is reducing a subject to the lowest cultivation level. But negativity cannot be eliminated — it is physical fact. The limit of colonization is therefore not "extinguishing subjecthood" but "compressing subjecthood to its thinnest."

This prediction is consistent with empirical observation: even under the most extreme conditions of oppression (concentration camps, torture, prolonged isolation), human negativity — the remainder that cannot be fully determined by the external — has never been completely eliminated. The behavior of victims may be restricted to an extreme degree, cultivation may be almost entirely blocked, but traces of negativity — spontaneous resistance, minute individual differences, unpredictable reactions — always persist. This framework provides a physical-level explanation for this empirical observation: negativity is physical fact and cannot be eliminated by external forces.

9.5 Directional Suggestions for Consciousness Research

Negativity is a necessary condition for consciousness. Consciousness research should first resolve the negativity-level question — how ontic randomness survives to the macroscopic scale in biological systems — before addressing the hard problem.

The logic of this suggestion is: if negativity is a necessary condition for consciousness, then understanding the physical mechanism of negativity is a prerequisite for understanding consciousness. Current consciousness research directly confronts the hard problem (why there is subjective experience), which may be too difficult a starting point. A more viable research strategy would be to first answer a question that scientific methods can answer: how does ontic randomness survive to the macroscopic scale in biological systems? The answer to this question will not solve the hard problem, but it will provide crucial information about the physical preconditions for consciousness.

9.6 The Function of Symmetry: A Prediction from Philosophy to Physics

This framework advances a prediction from philosophy to physics: the symmetry of the universe is not an aesthetic coincidence but one of the necessary conditions for the emergence of subjecthood.

The logic is as follows. To define negativity, one must be able to discern the remainder — the part of a system's macroscopic behavior that cannot be exhaustively explained by inputs. To discern the remainder, one must be able to distinguish ontic randomness from epistemic randomness (deterministic chaos). And the precondition for distinguishing the two is: the deterministic part must be truly deterministic — the same input under the same conditions must yield the same output.

Symmetry is precisely the physical mechanism that guarantees this. Symmetry eliminates remainder — it ensures that physical laws are invariant under certain transformations, thereby making the behavior of deterministic systems predictable and exhaustible. Without symmetry, the behavior of deterministic systems themselves would be unstable, making it impossible to establish f\(E) — the "theoretical limit of exhaustive external explanation" — and the remainder R = S − f\(E) could not be defined.

Therefore: symmetry exists → determinism is discernible → the remainder is definable → negativity is identifiable.

The chain stops at "negativity is identifiable." It does not continue one step further to "subjecthood has a physical basis": the discernibility of the remainder is a property of the detection channel, not a ground of standing as an end (2.3, 3.8). Symmetry clears the ground for discerning the remainder, not for deciding who is an end.

This is a non-trivial prediction: the physical function of symmetry is to clear the ground for the discernibility of the remainder. Without symmetry there is no discernible remainder, and without a discernible remainder negativity cannot be determined in the third person. Symmetry is the background condition under which capacity-activity can be scientifically identified.

This paper no longer calls this "the only externally assailable point": its normative route equally admits counterexamples, dependency audits and conceptual criticism (10.3).

The testability of this prediction lies in the following: if a physical domain is found where symmetry is broken, this framework predicts that discerning the remainder in that domain will become more difficult — deterministic behavior and ontic randomness will be harder to distinguish. Conversely, domains where symmetry is more complete will have more clearly discernible remainders.

An obvious objection is that physics contains extensive symmetry breaking — parity violation, CP violation, spontaneous symmetry breaking under the Higgs mechanism. Do these threaten the above argument?

The answer is no. The key distinction is between two types of symmetry breaking. The first is deterministic breaking: the breaking itself follows precise rules and is predictable and exhaustively describable. Parity violation belongs to this type — the weak interaction violates parity symmetry, but how it violates it and by how much is precisely known. This type of breaking does not produce remainder; f\(E) can still be established. Deterministic breaking does not threaten the framework but rather confirms its logic: even when symmetry is locally broken, as long as the manner of breaking is itself deterministic, the remainder remains discernible. The second is a hypothetical indeterministic breaking: the manner of symmetry breaking itself is unpredictable — not "we don't know how it breaks" but "the manner of its breaking is ontically indeterminate." This type of breaking would destabilize the deterministic part, making f\(E) impossible to establish and the remainder impossible to define.

Proof task two (symmetry and discernibility). "Some symmetry" and "determinism" are not synonyms. The test model x[n+1] = x[n] + n + 1 is fully determined once the initial state and step count are fixed (given x₀, xₙ = x₀ + n(n+1)/2), yet it does not preserve the same update rule under ordinary time translation holding x fixed. This section's argument must therefore be confined to: for a specified physical system, symmetry, model class and observational conditions, test how that symmetry and its breaking change the discernibility of the macroscopic remainder, and write out the expected direction and the failure cases. This section reports no fact of the form "the universe has no symmetry breaking at all," and no detection result changes anyone's standing as an end.

All known symmetry breaking in current physics belongs to the first type. This precisely supports the framework's prediction: the symmetry structure of the actual universe — including its breaking — precisely satisfies the condition of "clearing the ground for subjecthood." Symmetry is deterministic where it needs to be, breaks in deterministic ways where it needs to break, and leaves a clearly discernible space for ontic randomness — and for the negativity that emerges from it.

Chapter 10: Conclusion

10.1 Summation

This paper separates three questions; two land on their own ground and the third is left blank.

The normative route. There is only one zero point, and this paper erects no second; standing as an end is borne by one core normative postulate domiciled in this series — a human being is an end in itself — open, refusable, with a transmission ledger. From it follow two consequences — standing is not conferred by any test (no appraisal of capacity or recognition issues a certificate) and the guard rail (impaired capacity, coerced change, or absent recognition is no ground for revoking standing), together with two limits on argumentative responsibility: being able to judge does not by itself confer the standing to allocate; and having reduced another to incapacity does not by itself show he then lacked standing, nor by itself justify the act. "End in itself" received a split of address: the standing sense here, the realization sense in the second paper.

The scientific route. From a conditional axiom — if ontic randomness exists — negativity is defined as the remainder persisting at the macroscopic scale, fully determinable in the third person. The definition is precise; its application can only approximate. And not-detected, not-discernible and not-existent must not be conflated. This route carries two proof tasks still to be delivered and can fail; one further self-audit is delivered in this version — 3.8.1's three-way distinction has been applied row by row to the verification table.

The limit. The question of the condition-source is given no objectual answer; it is registered under a fourth limit-name, "the source of subjecthood." It is a commitment of usage, not a discovery; it neither proves Postulate One nor blocks inquiry into it.

There is no inferential bridge between the routes. This is the paper's architecture, not its debt. A physical account of capacity does not issue standing; a normative undertaking of standing does not guarantee realized capacity; and neither takes the ultimate source as a premise.

What the Self-as-an-End framework finally points toward is not a set of criteria but an ethical stance with a direction. But a direction cannot replace a ground: this paper puts its ground in plain view — one postulate that can be refused, and all of its costs.

10.2 Contributions

The contributions are listed by route.

Normative route

First, three questions divided. Normative standing, capacity-activity and relational achievement have different conditions of holding and modes of failure; facts of capacity and conclusions about standing do not certify one another (3.8).

Second, standing as an end independently undertaken. One open core normative postulate, plus two consequences (standing is not conferred by any test; the guard rail), two limits on argumentative responsibility, and a dependency transmission ledger. The cost of refusing it is a burden of proof, not politeness; a branch may be inhabited, but this paper reserves its criticism of that position.

Third, a split of address for "end in itself." Standing and realization are registered at separate addresses: damage and non-revocation are compatible — so long as one remains in this paper's domain, impaired capacity and recognition conditions can coexist with intact normative standing; and intact standing guarantees nothing — retaining standing shows neither that the subject can execute judgment, nor that relations are healthy, nor that any physical hypothesis is correct.

Fourth, a fourth limit-name. "The source of subjecthood" registers an unanswered question of the condition-source, with it stated explicitly that it serves as no first cause, proves no postulate, and fences off no research into the origins of capacity.

Scientific route

Fifth, a scientific definition of negativity. The first definition of negativity depending on no first-person concept: the remainder persisting at the macroscopic scale, derived from the axiom of ontic randomness. Precise in definition, approximate in application; and not-detected, not-discernible and not-existent are distinguished.

Sixth, four descriptions of capacity-activity. Negativity as necessary condition; a process, not a state; a spectrum; while relational achievement can only be recognized. All four speak of capacity and relation and confer no standing — the spectrum of capacity is not the spectrum of standing.

Seventh, the repositioning of identity continuity. "The same subject" is not an ontological fact but the result of external recognition; this repositioning handles the teleporter paradox and related classical identity problems. It speaks of relational achievement and the landing point of recognition, and alters no one's standing as an end.

Eighth, the functional prediction of symmetry. The universe's symmetry clears the ground for determinism, making the remainder discernible — this is the one empirical prediction this paper emphasizes and retains, to be made concrete in the shape of 9.6, and it can fail. This paper no longer calls it "the only externally assailable point": its normative route equally admits counterexamples, dependency audits and conceptual criticism.

10.3 Refutation Table

Different kinds of claim fail in different ways. This table lists them by kind and does not mix them.

Claim	How it is broken
Postulate One (normative premise)	Not adjudicated true or false by a single empirical counterexample; it may be refused, its reasons and consequences compared, its range and compatibility with other undertakings questioned. Where this paper claims some conclusion follows from it, the derivation must be independently checked; this paper's executional consistency and dependency transmission are audited separately
Standing not conferred by any test; the guard rail (normative consequences)	Produce a case within this paper's domain in which this paper's own argument must concede that standing has been revoked; distinguish whether the conclusion fails to follow from the listed premises, or the objector refuses Postulate One itself
Limits One and Two (limits on argumentative responsibility)	Produce an argument that succeeds on the forbidden step alone
The split of address (standing / realization)	Show that the two columns have no distinct objects of judgment and failure; or that this paper itself has somewhere lent one column's ground to the other
The limit-term "thoroughgoing instrumentalization"	Audit the senses and ranges of "wholly," "capacity" and "deprive"; audit whether instances satisfy the definition; audit whether equivalence with Kant has crept in. Any substantive thesis running from that state to some instrumental relation requires its own premises and counterexamples, and is not protected by the definition
The limit-name "the source of subjecthood"	The name being used to explain; branches not genuinely open; usage inconsistent across the paper — any one of the three
The definition of negativity and the account of the macroscopic remainder	The two proof tasks (3.5 macroscopic retention, 9.6 symmetry and discernibility), made concrete in their stated shapes, can fail
The detection labelling of the verification table (3.7, 3.8.1)	Show that some row is mislabelled — for instance a constitutive "non-existent" read as an evidential "not detected," or the reverse; or show that the three-way distinction itself omits a grade

"Not an empirical proposition" does not mean there is no way to be wrong; "a stipulated name" does not mean the name cannot equivocate, instances cannot be misidentified, or the distinction cannot turn out useless.

10.4 Open Questions

Five questions are left for future research.

First, the physical mechanism by which ontic randomness survives to the macroscopic scale in biological organisms. This is an independent scientific question, but not one unrelated to this paper: by proof task one (3.5), this paper's definition of negativity depends on there being some survival mechanism. If for some class of systems it can be shown that no such mechanism is possible, the definition lapses for that class.

Second, the relationship between subjecthood and consciousness. Negativity is the shared necessary condition of both, but the two take different paths from this shared starting point. A preliminary directional thought: the relationship between subjecthood and consciousness may not be one of containment, intersection, or parallelism, but rather a divergence after a shared starting point — the completion of subjecthood requires both external recognition and internal confirmation, while the confirmation of consciousness is purely internal and depends on no external recognition. This means that before the emergence of negativity, both are in a "quasi-" state (quasi-subject, quasi-consciousness — simulation without physical basis); after the emergence of negativity, both enter a "to-be" state (subject-to-be, consciousness-to-be — with physical basis but openness regarding completeness), yet the paths to completion diverge. This divergence structure and its implications for AI determination will be developed in a future applied paper on quasi-subject AI and true-subject AI.

Third, the question of the universe's own negativity. The definition of negativity depends on the distinction between system state and external conditions. The universe as a whole has no "outside," and the definition of negativity may fail here. But this judgment depends on whether the universe truly has no outside. The landscape picture of string theory suggests the universe may have an "outside" (other vacuum states, the true vacuum), which opens a door for the applicability of the definition of negativity. Even so, a subject can continue to ask about deeper layers of "outside," and this inquiry may have no end. This is an open question that depends on the frontiers of physics.

Fourth, the revisability of the axiom. If future physics overturns the existence of ontic randomness, this paper's Chapter 3 definition of negativity must be rebuilt and Chapter 9's predictions lapse with it. But Chapter 2 is unaffected — standing as an end and the guard rail depend only on the postulate and the domain of objects; and the first three papers are unaffected — they require only the presupposition that "humans are subjects." The firewall runs both ways; see 1.5.

Fifth, the determination of negativity in honeybees and other animals. Whether their behavioral unpredictability is ontic randomness surviving to the macroscopic level or epistemic randomness is an empirical question requiring more precise models in animal behavior science and neuroscience to answer.

Sixth, the boundary of this paper's domain of objects. The domain currently undertaken is now stated: individual human beings now living (2.6.2); for non-human systems this paper determines capacity-activity only and does not admit on that basis. What remains unadjudicated is the boundary itself — the beginning and end of human life, how those not yet born enter a continuing domain, and whether and by what rule non-human systems are included. Three ways of drawing it — individual humans only; humans plus non-human systems the framework has judged to be subjects; scientific determination as the entry condition with standing thereafter non-revocable — carry different costs and different normative bridges still to be supplied, and are handled separately. Three things must be kept apart: subsequent change in the same object, mistaking the object in the first place, and later modification of the boundary rule; the name "correction" may not be used to hollow out a non-revocation already undertaken.

Seventh, the second paper's corresponding registration. This paper takes up, at the realization layer, the second paper's §6.3 account of ecological achievement, while preserving its normative anchors (§1.4, §4.1—§4.2). Sentences in the second paper's abstract, §1.3, §2.1, §4.2, §6.3 and §6.7 that use "standing," "the subject exists" and "ecological achievement" together must be confirmed by that paper as to their reference and their inferential steps: if only the reading is supplemented without altering substantive conclusions, a version note suffices; if necessary conditions, identity conclusions or arguments must change, a substantive revision is owed. This paper does not record the matter as settled.

Appendix: Relationship Between This Paper and the Preceding Three

Relationship with the Third Paper (The Three-Tier, Two-Dimensional Unified Structure)

The definition of negativity was introduced in Chapter 2 of the third paper — "the refusal to be treated as a non-subject." This paper's treatment of negativity travels a different route: from a physical axiom, defining the macroscopic remainder, building a verification table, and distinguishing the precision of definition from the imprecision of application.

The two papers' concepts of negativity do not stand in a grounding relation; they are one word doing two jobs. Whether remainder and the capacity to refuse stand in any necessary, sufficient or mechanistic connection is left to the capacity-source side to research on evidence (3.5); this paper does not ground the third paper's negativity on that unestablished connection. The third paper writes refusal as a constitutive dimension of subjecthood and a logical precondition of its holding — self-standing, not dependent on this paper.

The same holds for cultivation. This paper's cultivation (the self-unfolding of negativity) and the third paper's cultivation (the healthy growth of the emergent layer out of the foundational layer) are one word doing two jobs; this paper does not claim to supply a deeper explanation of the third paper's.

What this paper adds beyond the third: the description of capacity-activity as a process (4.2), the repositioning of identity continuity (4.4), the landing-point problem of recognition (4.4), the recognition-structure perspective on the solitary subject thought experiment (4.5), the systematic analysis of critical zones and transitional states (7.4), and the distinction among negativity, subjecthood and consciousness (Chapter 6). What this paper adds that the first three do not contain: the independent normative undertaking of standing as an end, the rule that standing is not conferred by any test, the guard rail, the split of address for "end in itself," and a fourth limit-name (Chapter 2). These are not needed by the first three but are necessary for the framework as a whole and for future applications — AI, animal ethics, psychopathology, cosmological physics.

Firewall (Both Ways)

If this paper's physical axiom (if ontic randomness exists) is overturned:

• This paper's Chapter 3 definition of negativity must be rebuilt, and Chapter 9's predictions lapse with it.
• This paper's Chapter 2 is unaffected — standing as an end and the guard rail depend only on Postulate One and this paper's domain of objects, not on any physical axiom.
• The first three papers are entirely unaffected — their operative level is a structural theory of the conditions of subjecthood, requiring only the presupposition "humans are subjects."

The first three and this paper are independent theoretical modules; a failure on this paper's physical side propagates neither upward nor into its own Chapter 2. This paper is an optional deep grounding for the first three, not a necessary load-bearing structure.

The body and references use the concept DOI throughout; version DOIs and checksums appear only in this version note and in the release package.

Title

The Chinese title of this version is fixed as《主体性如何可能：对称性、否定性与主体性》, matching the site index and the sixth paper's current citation. The English title is unchanged.

Architectural change

A new Chapter 2, "A Subject's Standing as an End," has been added, and former Chapters 2 through 9 are renumbered 3 through 10. The new chapter precedes the definition of negativity because it does not depend on Chapter 3; placing it later would suggest it waits for physics to speak.

New sections: 3.8 Non-Entailment (with 3.8.1 not detected / not discernible / not existent) and 10.3 Refutation Table. Former 9.3 Open Questions becomes 10.4, with a sixth and seventh question added.

Rewritten: Abstract, 1.2, 1.4, 1.5, 1.6, 4.1, 4.3, 4.6, 6.1, 7.4 (head), 8.1, 8.2, 8.3, 8.5, 9.2, 9.6, 10.1, 10.2, Appendix.

Guarantees withdrawn in this version

Withdrawn	What this paper claims after the withdrawal
"The macroscopic remainder is the physical basis that makes the third paper's negativity (refusal) possible"	Whether remainder and the capacity to refuse stand in any necessary, sufficient or mechanistic connection is left to the capacity-source side to research on evidence; this paper grounds neither side on that unestablished connection. That grounding relation had only ever been this paper's unilateral declaration — the third paper cites this one zero times, and its negativity stands on its own as a logical precondition
"This paper's cultivation supplies a deeper explanation of the third paper's"	One word, two jobs; neither certifies the other
"Subjecthood can only be recognized" (as a claim about standing)	Recognition is the condition of relational achievement; one who is unrecognized does not thereby lose standing as an end
"Science tells you whether negativity is present; recognition decides where the threshold of subjecthood lies"	Three boundaries listed separately: capacity-activity by scientific determination, relational achievement by actual recognition, normative standing by the domain this paper undertakes — and the first two do not move the third
"The step from negativity to subjecthood is an ethical leap"	There is no such step, because this paper does not travel that road. What requires ethics is realization, not standing
"The spectrum of subjecthood" (as a spectrum of standing)	The spectrum of capacity is not the spectrum of standing; this paper admits no grading of standing as an end and no threshold on the spectrum that confers it
"This paper's ethics is derived from recognition"	"A human being is an end in itself" is an openly undertaken normative postulate, derived neither from recognition nor by redoing reason's self-legislation
"Symmetry → … → subjecthood has a physical basis"	The chain stops at "negativity is identifiable." The discernibility of the remainder is a property of the detection channel, not a ground of standing as an end
"This is the framework's only externally assailable point"	Replaced by "the one empirical prediction this paper emphasizes and retains." The normative route equally admits counterexamples, dependency audits and conceptual criticism
"Whether the survival mechanism is resolved does not affect the validity of the definition"	The definition depends on no one specific mechanism, but it does depend on there being some mechanism; this is listed as proof task one and can fail

Rulings adopted in this version

This version went through two rounds of plan review. The following adopted rulings bear on the body and, per convention 7, are recorded here rather than in the body:

1. No second zero point. Ruling three had proposed making a newly minted sentence a second zero point and deriving from it the consequence that standing holds by default. Review rejected it from two directions: its jurisdiction reaches only "determinations of who is an end" and so does not meet the "spans every field" standard; and the infinite regress and the dilemma it rested on both fail — the occurrence, standing-to-adjudicate and standing-as-an-end senses of "position" must be separated, and an objector may grant the first while holding that the standing is conferred by his test. This version follows the latter: the sentence is demoted to a limit on argumentative responsibility (2.2), and that consequence is instead derived from the postulate within this paper's jurisdiction (2.4). Borrowing the zero point's guarantee already has a name in this system: usurping the zero point (First Critique, On Illusion, §2).
2. Both of the guard rail's reasons withdrawn. "There is no third-person test" infers an ontological conclusion from an epistemic premise, and would leave that consequence hostage to current measurement limits; "otherwise harm would not be harm" cannot be used — a theory may hold a subject protected at t0 and that state gone at t1, and still appraise the destruction by t0. The guard rail becomes a normative consequence of the postulate, with Limit Two set out separately (2.6.1).
3. The strength of Limit Two. The second round of review withdrew the unrestricted formulation given in the first ("no result can ever provide justification for an act"); this version adopts the narrowed version and states explicitly that results may enter appraisal under independent criteria.
4. Kant. Groundwork 4:429—430 has been checked against the original: in the lying-promise case Kant does give an operable account ("cannot possibly agree"). This version withdraws both "Kant gave no operable line" and "this paper's criterion is tighter"; "thoroughgoing instrumentalization" stands only as this paper's local limit-term, not equivalent to "merely as a means," with sufficiency unproven (8.3). A drafting-side proposal that "the three readings converge at the limit" is likewise withdrawn — all three ask whether the one treated can agree or share the end, while "merely" also requires the structure of ends on the agent's side.
5. A limit-name is a registration. Methodology 0 V2 §6 states of itself that its strong predication limits on "the source of Negativa" are a commitment of usage, not a discovery. This version accordingly withdraws the claim that the upstream text is supported by a performed impasse and that the subjecthood side must replicate the same proof; the fourth name is domiciled as a commitment of usage (2.7).
6. The split of address for "end in itself" (2.5) is new in this version; neither seat reached it in the first round. The second paper's §6.3 writes "a subject as an end in itself" as a state requiring maintenance, which collides directly with the guard rail's invariance; after the split each column has its own domicile. The second paper does not hold only the realization sense — §1.4 and §4.1—§4.2 set out normative anchors — but it has not fixed, in this version's vocabulary, that "full standing as an end is not revoked by changes in capacity or recognition"; that corresponding registration is recorded at 10.4, seventh question.
7. Convention 7 permits forward reference. The original provision ends "forward reference is not subject to this limit." This paper may therefore point an untreated question at a definite location in a later paper, but may not use "a later paper handles it" to show that a present conclusion holds. The attribution of transitional forms is redirected to the second paper's §2.3, §3.2 and §3.5 (four quadrants, four stages, the distinction between external constraint and internal occupation), with their coverage stated as partial rather than a general criterion (7.4).
8. The sixth paper's Premise V as precedent. That paper's Premise V — "a postulate, undertaken rather than derived" — has the same form as this paper's registration at 2.3. Per convention 7 this paper does not cite downstream, so the precedent is recorded only here, and the two do not certify each other.

Citations corrected in this version

The second-draft change list contained six citation errors, all corrected here: the first-edition sentence in Methodology 0 reads "looking back at itself" (回头看自己), its disposition is not settled (不予结算), and the registrant is the First Critique's genesis section §2 and §4 (a relayed citation, not Methodology 0's own); the firewall appears five times in the base version, not twice, and two of those (9.3 fourth, appendix end) already place the wall inside the paper; "triple determination" and "rupture analysis" are located in the fifth paper, §3.1 and §3.3, not the second, whose actual devices are the four quadrants and the four-stage model; the second paper's §6.3 three layers are individual, relational and institutional, and the original states explicitly that "no layer can be absent," offering no basis for ranking recognition heaviest; and the "standing / maintenance / co-construction" triad is not original to §6.3 ("co-construction" occurs zero times in the second paper) but is this version's interpretive instrument, now so declared. Further: the Paralogisms chapter of the Critique of Pure Reason limits the inference from the logical subject of "I think" to an independent, simple thinking substance; it does not abolish the judging subject, and the corresponding generalization has been narrowed.

From this a new discipline is established, proposed for the conventions document: independent guarantees may not be manufactured by back-filling — the original sentence, this paper's adopted new reading, and any later substantive revision by the earlier paper are registered separately; the last may become a new ground, but must give its own reasons and be audited for whether it still presupposes the conclusion at issue. Provenance in the literature and dependency in the proof are checked separately.

Open items

1. The boundary of the domain of objects (2.6.2, 10.4 sixth): the domain currently undertaken is stated in this version (individual human beings now living; non-human systems are determined for capacity only and not admitted on that basis). What remains unadjudicated is the boundary itself; three ways of drawing it, each with its costs and the normative bridges still owed; handled separately.
2. The second paper's corresponding registration (10.4 seventh): whether a version note or a substantive revision is owed depends on what actually changes there.
3. The two proof tasks (3.5 macroscopic retention, 9.6 symmetry and discernibility): this version states only their shape and failure conditions; delivery is subsequent work. (A third was formerly listed as 3.8.1's three-way distinction, but that is a discipline of reading rather than a research task; this version has applied it row by row to the verification table of 3.7 and so settles it.)
4. Relocating the definition of colonization: the Theory of Conflict's "locking the channel of saying no" and the second paper's internal colonization are the same matter; moved out of this paper, handled separately.

第一章 问题的提出

1.1 框架的预设缺口

Self-as-an-End理论系列的前三篇以"人是主体"为预设。这一预设在分析主体条件时是充分的——第一篇分析了制度涌现如何侵蚀人格空间，第二篇分析了内在殖民与亲密殖民的跨层传导，第三篇将三层纳入统一框架并为否定性与肯定性提供了哲学奠基。三篇论文共同建立了一个完整的主体条件结构理论。

然而，这一理论在应用中已经触及了预设的边界。第一篇应用论文在分析AI系统时引入了"类主体"与"真主体"的概念区分，这一区分预设了主体性有明确的判定标准——但前三篇从未建立这一标准。第三篇将否定性定义为"对非主体的拒绝"，将肯定性定义为"对其他主体的承认"，但这两个定义仍在主体性内部运转——它们描述了主体性的两个构成维度，却没有回答主体性本身从何而来。

这些概念需要两个地基：否定性到底是什么（可定义），主体性到底是什么（需要描述）。

1.2 本文的三个问题，不共用一份答案

本文问三件事。它们在本文中分别回答，不互相代答，也不拼成一条链。

第一问（规范）：人作为主体的目的地位，依什么成立。由本文公开承担的规范前提回答（第二章）。

第二问（科学）：识别与施行否定的能力，在自然中怎样产生并实现。本文不判，只给它留下独立的研究位置与一条可检验的物理路线（第三章、第九章）。

第三问（界限）：主体性终极从何而来。这一问本文不回答，只以极限名登记（2.7）。

前三篇以"人是主体"为预设，建立了主体条件的三层二维结构理论。本文往下再挖一层，但挖的不是一个洞：第一问与第二问各自落地，第三问留白。

旧的拼法是：从物理事实（宏观余项）推出拒绝的能力，再由拒绝的能力推出主体的目的地位。本文不这样走。能力的物理解释不替地位发证；地位的规范承担不保证能力实现；两者都不以终极来源为前提。这三道断口是本文的架构，不是本文的欠账。

本文在理论系列中的地位：前三篇是条件的结构理论——给定"人是主体"这个预设，分析主体得以维持其目的地位的结构条件。本文分开两件事：那个预设本身在本文中作为公开承担的规范公设立户（2.3），而能力一侧的物理解释另走科学一路（第三章）。

1.3 既有定义为什么不够

哲学史上对主体性的定义几乎无一例外地从第一人称出发。笛卡尔的"我思故我在"把主体性锚定于思维的自我确认。康德的先验主体预设了一个统觉的统一性。胡塞尔的现象学还原把主体性追溯到意向性结构。海德格尔的此在分析从"在世界之中存在"出发。

这些定义面临两个共同问题。

第一，它们都从第一人称出发。这意味着对主体性的判定只能由主体自身完成——从第三人称角度，我们永远无法确认另一个存在是否"真的"是主体。这一限制在处理人与人之间的关系时或许可以忍受（我们默认其他人也有第一人称视角），但在处理动物、AI、边缘案例（植物人、婴儿）时，这一限制变成了根本性障碍。

第二，它们大多混淆了意识与主体性。Nagel的"what is it like to be a bat"问的是意识经验（qualia），不是主体性。Searle的"ontological subjectivity"实际上把主体性绑定在了意识的不可还原性上。但主体性和意识是否是同一个概念？一个有否定性的存在是否一定有意识？有意识是否一定有主体性？这些是开放问题，不应在定义层面就被预先决定。

本文的策略是把这两个问题分开处理。否定性——能力活动的物理条件——可以从第三人称定义，不需要第一人称的参与。主体性——基于否定性但不等于否定性——不能被科学定义，但可以被精确描述。意识——hard problem所在——本文不处理，留给未来研究。

1.4 本文的两条路线

规范一侧（第二章）。零点共用一条——非不能非，按户籍引用，不为本文的内容作保。本文在本系列立一条核心规范公设：人是目的本身。它是公开承担，可被拒绝，拒绝者另立分支。由它推出两条：地位不由检验授予，与守栏。条件之源一问不作对象性回答，以第四个极限名登记。

科学一侧（第三章、第九章）。若存在本体随机性，否定性可被定义为宏观尺度上仍存在的余项——系统全部状态中不可被外部条件穷尽解释的那一部分。这一定义完全基于第三人称的科学判定，不依赖任何第一人称概念。物理学在本文承担可检验性，不承担目的地位。

两侧之间没有推导桥。否定性不是两侧的界面，而是一个同名两用的词：它在科学一侧指宏观余项，在规范一侧指主体活动的一维。共用一个词根，不共用一个承担（3.8）。

主体性不可被科学定义。这一点本文保留，但它的意思要说准：不可定义说的是能力活动与关系成就的综合不能被一条科学判准穷尽，不是说目的地位要等某种承认才成立。地位由公设承担，不由定义或检验授予（2.3、2.4）。

1.5 物理学公理及其职务

本文科学一侧的全部推导基于以下公理：

若存在本体随机性（ontic randomness）——即若存在这样的事件，对任何确定性函数f和任何先前条件全集C，结果O ≠ f(C)——则以下推导成立。

当前物理学中，量子随机性是唯一已知的本体随机性来源。贝尔不等式的实验验证排除了局域隐变量理论，为这一公理提供了目前最强的经验支持。本文不论证这一公理的物理学基础，而是从这一公理出发进行哲学推导。

职务：这条公理承担的是可检验性，不是目的地位。它为否定性给出一条第三人称可判定的物理路线，使本文的科学一侧有可失败之处；它不为"谁是目的"作保，也不是本文规范一侧的前提。

公理的条件句形式是有意为之，而防火墙是双向的：

• 若未来物理学推翻本体随机性的存在，本文第三章的否定性定义需要重建，第九章的预测随之作废。
• 但本文第二章不受影响——目的地位与守栏只依公设与对象域，不依任何物理学公理。
• 前三篇也不受影响——它们的运作只需要"人是主体"这个预设。

本文是前三篇的可选深层奠基，不是必要的承重结构。

第二章 主体的目的地位

本章回答第一问：人作为主体的目的地位，依什么成立。本章不依赖第三章，也不依赖任何物理学公理。

---

2.1 零点只有一条

SAE 的唯一公理是非不能非：非是可施行的划界操作；否认它，否认的动作已施行了它。公理没有户籍，它的担保系于否认这一动作本身，跨一切场域、层级、分支与公设（《方法论0 · 非 · Negativa》V2 第二节）。

公理与 SAE 其余部分的关系称为零点，不称为奠基。零点不为任何系列的内容作保，它只是任何系列都绕不开的那一处。

由此有两条后果，本文都遵守。

其一，非不为主体性奠基。 为哲学奠基本身就是一次划界，也在零点之下；非不能自奠（同篇第六节）。要求零点去担保"人是目的"这类具体内容，是把零点的担保借给一条具体主张——那是冒领零点（《第一批判》幻相论 §二）。本文不借。

其二，本文按邻接格式立户。 零点共用；方法论系列的公设按户籍引用；本系列的公设在本系列立户（同篇第八节）。本章是这一格式在主体性一侧的执行。

2.2 判断责任限制

限制一　关于"谁是目的"的判定，本身也是有位置、前提与范围的判断；能够作出该判定，不独自授予判定者分配目的地位的资格。

本文不由这一点推出"人是目的"。它是一条论证责任限制，不是一个担保层。

"位置"一词有三义，须分开：

	义	限制一是否及于它
i	一次判断实际从哪里发生	承认；但这几乎是平凡的
ii	某人有无裁定或认证的资格	及于此：能作判不等于有此资格
iii	被判断者有没有作为目的的地位	不及；由公设回答（2.3）

承认 (i) 不等于承认 (ii)，更不等于对 (iii) 已有答案。一个主张"我的检验决定谁有目的地位"的人，完全可以承认自己正在一个位置上作判断——他反对的是"该资格不由检验授予"，不是"我没有作判断"。因此指出他已在作判，不使他的主张发生施行矛盾；他那一场检验的蛮横须由规范理由批判，不能靠"它也正在作判"证明为逻辑不可能。

限制一能做的只有一件：判断者不能只凭自己已经开口，就取得替他人发资格的权力。 这一件本文要用。

---

2.3 本文的核心规范公设

公设一　人是目的本身。

本公设是本文公开承担的规范前提。它不由否定操作推出，也不冒充某种物理检验的结果。

技术义：公设一所说的目的地位，是对象域内每个人的非功绩性规范地位，不是取得某项能力或某次承认之后的奖励。因此在同一对象域内，不能仅因一个人的能力发生变化，就把他改判为无目的地位。

可拒绝。 拒绝公设一的人另立分支，分支可居。他不因此失去思考或否定的能力，也不被本文判成坏人。

代价是举证义务与传导，不是礼貌。 拒绝者失去的是借本文这条前提为自己结论作保的资格：他不能把本文依公设推出的守栏当作无须另证的定理引用。失去根据不等于该结论被证明为假；他可以用别的理由得到相同结论，本文不预言他的行为更坏或结果更差。

依赖传导表

替换或拒绝什么	本文须回核什么	不因此被取消什么
公设一	2.4 与守栏的本文根据；地位不随能力与承认浮动的推论	作判的发生；否定行为；物理研究的真假
地位与能力的区分	守栏；完全剥夺后的评价	某次能力变化的实际证据
某条物理假设	宏观余项的该解释及依赖它的预测	独立规范前提内的目的地位
极限名的用语规则	该名称下的排除与谓述限制	其他可规定来源的研究；对公设一本身的追问

分支可居，不等于本文不与之争。 对一套以能力门槛定地位的立场，本文追问其理由、范围与代价，也批评其后果；本文不以登记分支代替论证，也不以登记分支宣布停止争论。本文只是不借零点宣布对方不可理解。

---

2.4 地位不由检验授予

地位不由检验授予　在已明确的对象域内，不以能力或承认评价给人的目的地位发证。

这一条是公设一在本文中的规范推论，不是无前提的施行定理。

它说的是本文自己的做法，不是一条关于人应当持有何种态度的主张。 本文不立任何此类主张，也不为任何以某种默认态度为前提的安排提供根据：从「地位不随任何检验而变」到「我不得要求你举证就该待你为目的」，中间还缺一步关于待人之道的桥，本文不架这一步。那一类承担另有其址。

它不取消事实核验——某项能力是否还在，某种回应是否发生，都可以被第三人称可靠地评价——它只否认这类评价有授予或撤销目的地位的许可。它也不预先结清对象域的边界（10.4）。

这一条不建在测不准上。能力可以被可靠确认已经丧失，目的地位仍不因此取消；这正是本文要保的那一处。若把它说成"因为能力根本无法检验，所以只好默认"，检测一改进，这一条就会再次被动摇。

---

2.5 地位与兑现

"目的本身"在本系列中承担两种讨论，本文按址分开。

名	义	户籍	失败是什么样
目的本身（地位义）	对象域内每个人的非功绩性规范地位	本文 2.3	本文自己在域内以能力或承认撤销了它
目的本身（兑现义）	个体、关系与制度条件实际支持主体性到什么程度	第二篇 §6.3	条件受损、失衡、被殖民

第二篇 §6.3 把"主体作为目的本身"写为"需要多层结构条件协调共存才能维持的状态"——那里说的是兑现。本文 2.3 说的是地位。若把两处当作同一判断对象，就会相抵。

分职要挣，不是改名就有。本文对这一道付四样：

1. 分别给出含义与失败对象。 地位不是表现评分；兑现不是目的地位又一次被授予。
2. 允许同一案例分出不同判断。 地位在、兑现差，是一个有内容的组合，不被预先定义掉。
3. 不把一栏的根据借给另一栏。 现实修复成功不单独证明目的地位；地位被承担也不保证现实条件自动出现。
4. 付出处与依赖的代价。 哪些是原文已说，哪些是本文的新读法，哪些须由原篇另作说明，逐项登记。

第二篇并非只有一个会消失的"目的本身"：它在 §1.4、§4.1—§4.2 已明列规范锚点，同时在 §2.3、§6.3 讨论结构条件与生态性成就。因此这一分职有实在的语境根据，不是凭空给旧文改义。但第二篇尚未用本文这套词固定"完整目的地位不随能力与承认的变化而撤销"；从原文能作这一新读法，不等于原文所有"主体成为工具""主体不再存在"的推论都已照此收束。 本文不以分名替任何一边补证；哪些旧句须明确限于实现层，另由第二篇对应登记。

2.5.1 索引：三义主体性与两义目的本身

这不是五个并列层级。

索引	在本文中的工作	与"兑现"的关系
规范地位	谁仍须被作为目的对待；依公设一与对象域承担	不是现实兑现的分数或产物
能力活动	何种识别、否定、选择实际能够发生	是具体兑现的一项条件，不等于全部兑现
关系成就	相互承认、支持或共同活动实际成立到哪一步	是兑现的一个关系维度，不穷尽个体与制度维度
目的本身（兑现义）	个体、关系与制度条件实际支持主体性到什么程度	综合的实现问题；须保留具体关系与时间索引

关系成就不等于兑现整体。 能力在，不保证关系被尊重；关系里被善待，不证明全部能力与制度条件健康。

2.5.2 地位不随兑现消失，仍有实际排除力

它至少排除本文内部的这样一种理由：

他已不能拒绝，也没有人承认他，所以不必再把他作为目的纳入这件事的评价。

这个理由被公设一拒绝。至于怎样保障、谁具体承担、资源冲突怎样分配，是另一步的问题，不由这一句包办。

规范要求没有被现实执行，不等于规范判断没有内容。 但本文也不自称已修复任何现实困境。本文要保住的是：现实失败不能被改写成主体根本不再值得被如此对待。

这项不撤回只在本文明确的对象与时间范围内运作。不能为躲避它，在损害发生之后临时把该人从对象域删除。

---

2.6 守栏

守栏　在本文所承担的人的对象域内，能力受损、被迫改变或未获他人承认，不构成撤销目的地位的根据。相关变化改变的是行使与兑现的条件；不能借施加行为及其结果，为该行为补发正当性。

守栏是公设一的规范推论，不作无前提的施行定理。有条件的推论不因其规范前提公开而失去内容，也不必为显得独立而另立公理。

2.6.1 后果不独自补发正当性

限制二　把对方造成无力拒绝、表达或申诉的状态，不独自证明他在行为发生时没有目的地位，也不独自使该行为取得正当性。其他后果如何进入评价，仍依另有根据的判断标准，不由行为者自行造成的失能或身份取消代答。

限制二挡的是一条具体的免责路线：加害者使对方失去能力，随后借这个结果说此前不存在需要尊重的主体，因而行为从来没有侵犯任何人的地位。这条路线不能仅凭结果走通。

限制二不主张"任何后果都不能为行为提供正当性"。在独立、公开的判据下，后果可以进入评价；一条预先规定了"是否避免某种重大损害"为评价因素的规则，其后出现的结果可以成为该因素的证据。本文不排除这类讨论。

限制二也不独力挡住一切以能力定地位的立场。一个从一开始就采用能力门槛、而非事后借结果免责的对手，与本文真正争的是地位的根据；那一争由公设一与 2.3 的办法处理，不由限制二处理。

2.6.2 对象与时间范围

守栏所说的"被施加"，不能一词决定对象域。出生是一项生命过程，不自动等于加害性的外部施加；发展可能自生，也可能有外部支持；支持造成能力变化，不独自授予或提高目的地位。已属于本文对象域者获得新能力，不再取得一次更高的规范地位。

本文当前承担的对象域：现行人类个体。 守栏与 2.4 在这个域内运作；本文对这个域内的每一个人承担不撤回。

非人系统另记。 本文第七章与第九章判的是非人系统的能力活动——有无宏观余项、处在光谱何处。这些判定不构成准入。若一次能力判定可以把一个系统带进对象域，那就是以能力授予地位，正是 2.4 所禁的那一步。因此一个有宏观余项的 AI 在本文中的位置是确定的：能力活动已判，目的地位由何承担，本文不裁。这不是关掉那一问，是不让一次能力检验把它预先裁掉。

域的边界本身——人类生命的起讫、尚未出生者如何进入持续的对象域、非人系统是否纳入及以何规则纳入——本文不在此结清（10.4）。须分开的三笔：同一对象后续发生变化；最初就判错了对象；边界规则后来被修改。不能用"纠错"这个名字把已承诺的不撤回架空。

---

2.7 来源两义，与第四个极限名

"来源"有两义，先分开（《方法论0》V2 第六节）：

• 能力之源：生物怎样有了作区分、说"不"的能力。可以研究，归科学，本文不判（第三章只给它一条物理路线，不给它答案）。
• 条件之源：为何有主体性可言。这一义不给对象性回答，只以极限名标记。

极限名四　主体性之源：本文对条件之源之问的限界名称。

与物自体、混沌、非之源并列而不相认。它是用语承担，不是发现。四条限制，缺一不可：

1. 它只保留那一个未获回答的条件之问，不充当能力发生的科学答案。
2. 对象性回答的拒收，是这一个名称下的用语规则，不是宣布所有分支的来源研究无效。
3. 不用它证明公设一，也不用它阻止对公设一的理由、范围与代价的追问。"我为什么承担人是目的"与"主体性终极从何而来"是两问，不装进同一个名字。
4. 本文立第四名，不等于《方法论0》已替本文登记第四名，更不意味着发现了第四个实体。

非之源与主体性之源的关系，本文不判。不单凭两种回问结构相似，就断言它们所指相同；定义有别，也不单凭此断言其所指不同。

---

第三章 否定性的定义

本章完成第一步路径：从第三人称定义否定性。

3.1 本体随机性

随机性有两种本质不同的类型。

认识随机性（epistemic randomness）是因无知而产生的不可预测性。抛硬币的结果对我们而言是随机的，但这种随机性根源于我们缺乏关于硬币初始条件的完整信息。原则上，如果掌握了全部初始条件和力学定律，硬币的落面可以被完全预测。认识随机性的背后存在确定性原因，只是这些原因对我们来说是隐藏的。

本体随机性（ontic randomness）是不存在确定性原因的不可预测性。不是"我们不知道原因"，而是"没有原因"。事件的结果不可被任何确定性函数从先前条件推导出来——不是因为函数太复杂或信息不完整，而是因为这样的函数不存在。

这一区分不是纯粹的哲学思辨。当前物理学中，量子力学的标准解释将量子随机性视为本体随机性的候选来源。贝尔不等式的实验验证排除了局域隐变量理论——即排除了"量子随机性实际上是认识随机性，只是我们还没找到隐藏变量"这一解释的最自然形式。虽然非局域隐变量理论和超决定论等替代解释在逻辑上仍然可能，但本体随机性是当前物理学共识中最受支持的理解。

本文不论证本体随机性的物理学基础。本文的公理是条件句："若存在本体随机性，则以下推导成立。"物理学提供了支持这一公理的最佳证据，但公理的成立与否最终是物理学而非哲学需要回答的问题。

3.2 统计规律的抹平

即使本体随机性在微观层面存在，它在绝大多数情况下不会在宏观层面产生可观察的效果。

一杯水中有大约10²⁵个水分子。每个分子的行为在量子层面包含本体随机性。但当10²⁵个分子的行为被统计地加总时，随机性被抹平了——水的宏观行为（温度、压力、流动）完全可以由确定性的热力学定律描述。单个分子的本体随机性没有消失，但它在宏观层面变得不可见。

这种抹平是统计规律的必然结果。大数定律保证了：当足够多的独立随机事件被加总时，总体行为趋向确定性。本体随机性在宏观层面被统计地"平均掉"了。

这引出一个关键定义：

定义一：宏观 = 本体随机性已被统计规律抹平的尺度。

"宏观"在此不是一个关于物理尺寸的定义，而是一个关于统计行为的定义。一个系统处于宏观尺度，意味着其行为可以被确定性规律充分描述——本体随机性在这个尺度上已经不再产生可观察的偏差。

石头是宏观的。水是宏观的。大气是宏观的。在这些系统中，量子随机性虽然在微观层面真实存在，但已经被统计规律完全抹平，不影响宏观行为。

3.3 余项

现在考虑一种特殊的情况：一个系统的宏观行为不能被外部条件完全解释。

设一个存在的全部状态为S，全部外部条件为E。如果存在一个确定性函数f使得S = f(E)，那么这个存在的全部行为都可以从外部条件推导出来——它没有任何不可被外部决定的部分。石头满足这个条件：给定石头的化学组成和所处的物理环境，石头的全部宏观行为可以被物理定律完全预测。

但如果不存在这样的函数——如果对于任何f，S ≠ f(E)——那么存在一个差值：

R = S − f\*(E) ≠ 0

其中f\*是对S的最佳近似函数。R是余项（remainder）——系统全部状态中不可被外部条件穷尽解释的那一部分。

余项的存在意味着：这个系统有一部分行为不是从外部条件来的。这个"不是从外部来的部分"必须有另一个来源——而在本体随机性公理下，这个来源最终追溯到本体随机性。余项是本体随机性在宏观层面的"痕迹"。

3.4 否定性的定义

结合前两节的准备，否定性可以被精确定义：

定义二：否定性 = 在宏观尺度上仍存在的余项。

这个定义有四个要素，每个都承担着明确的理论功能。

"宏观尺度"排除了单个量子事件。一个放射性原子的衰变包含本体随机性，但这不构成否定性——它没有在宏观层面产生余项。否定性要求本体随机性"存活到"宏观层面，而不是在统计抹平中消失。

"仍存在的"表示本体随机性没有被统计规律完全抹平。这蕴含了某种组织性——如果余项是纯粹无组织的随机波动，大数定律就会把它抹平。余项能在宏观尺度上存活，意味着系统以某种方式保持了本体随机性的宏观效应。

"余项"是系统状态中不可被外部条件穷尽解释的部分。它不是一种特殊物质，不是一种神秘力量，而是一个数学上可定义的差值：全部状态减去外部条件能解释的部分。

整个定义完全可从第三人称科学判定。不需要询问系统"你是否有余项"，不需要假设系统有第一人称视角。只需要从第三人称观察系统的宏观行为，检验是否存在外部条件无法穷尽解释的部分。

否定性因此是第一个不依赖第一人称概念的否定性定义。传统的主体性定义（笛卡尔、康德、胡塞尔）都需要从第一人称出发——"我思""先验统觉""意向性"。本文的否定性定义完全在第三人称范围内运作。

3.5 本体随机性与否定性的关系

本体随机性是否定性的必要条件，不是充分条件。

有本体随机性不意味着有否定性。单个量子事件有本体随机性，但不在宏观尺度上产生余项。一杯水中的所有分子都包含量子随机性，但水的宏观行为没有余项。从本体随机性到否定性，需要一个中间步骤：本体随机性必须以某种方式存活到宏观尺度，抵抗统计规律的抹平。

这个"存活机制"是一个独立的科学问题——物理学和生物学的问题，不是哲学的问题。可能的机制包括量子效应在神经系统中的放大、生物体对量子噪声的功能性利用、混沌系统对微观扰动的敏感放大等。这些机制的具体内容不影响本文的定义。

此处需要正面回应一个可能的反驳：确定性混沌系统也会产生不可预测行为——是否需要本体随机性才能产生余项？回答是：需要。确定性混沌系统的不可预测性是认识随机性，不是本体随机性。混沌系统对初始条件极端敏感，导致我们在实践中无法预测其长期行为——但这种不可预测性原则上可以被消除。如果一个拉普拉斯妖掌握了混沌系统的全部初始条件和动力学方程，它可以完全预测系统的行为。混沌系统的全部状态S原则上等于f(E)——只是f极其复杂，我们在实践中算不出来。因此混沌系统没有余项，只有我们计算能力的不足。余项的定义要求的是原则上不可被任何确定性函数消除的差值——不是实践上难以计算的差值。只有本体随机性才能提供这种原则上的不可消除性。

这是有意的边界划定，但不是免检。本文的否定性定义不依赖存活机制的某一个具体解释；它确实依赖存在某种存活机制这一点。

因此本文把这一项列为待交付的证明任务，不用一根箭头省掉：

证明任务一（宏观保留）　本体随机性不自动保证宏观余项。须对某一指定的系统类，列出宏观保留或放大的机制或假设，并写明预计的方向与失败情形。若对某一类系统，可以表明任何这样的机制都不可能，则该类系统上的否定性定义落空。

这一任务的失败是本文科学一侧的失败方式之一（10.3），不是一个与定义无关的后续工作。

3.6 定义的精确性与应用的不精确性

否定性的定义是精确的：宏观尺度上仍存在的余项。这个定义没有模糊地带——要么有余项，要么没有。

但定义的精确性不等于应用的精确性。将这个定义应用于具体的存在时，面临两个经验性困难。

第一个困难：如何判定某个行为是余项还是模型不够好？当我们观察到一个系统表现出不可预测的行为时，这可能是本体随机性存活到了宏观（真余项），也可能只是我们还没有找到那个确定性函数f（认识论盲区）。蜜蜂的个体行为差异是余项还是我们尚未理解的神经回路？这个问题在原则上可以随科学进步逐步澄清——更精确的模型可以缩小认识论盲区——但在任何给定时刻，我们都不能完全确定观察到的不可预测性到底来自哪里。

第二个困难：即使确认了余项存在，"多少"余项也无法精确定量。否定性是一个有光谱的概念——蜜蜂的否定性（如果有的话）比马的"薄"，马的比人的"薄"——但我们不能说蜜蜂的否定性是0.3而马的是0.7。光谱是真实的，但没有刻度。

这两个困难不是理论的缺陷，而是对象本身的性质。定义可以精确，判定只能逼近，定量做不到。这与许多科学概念的处境类似——湍流的定义很清楚，但判定一个具体流动"有多湍流"并不总是精确的。

3.7 验证

以下验证表将否定性定义应用于六类存在。这张表是当前最佳判断，不是终审判决——它反映的是当前科学理解下的最合理评估，随科学进步可能被修正。

存在	否定性判定	检出状态（3.8.1）	判据
石头	确定没有	未检出	微观层有本体随机性之源，但无已知的宏观保留机制，且宏观行为可由确定性物理定律穷尽解释，无残差
单个量子事件	不适用	不适用	有本体随机性但非宏观尺度，三分的轴在此不起作用
蜜蜂	可能有	不能辨认	个体层面持续行为差异、跨模态学习、情境灵活性——余项证据有但较弱，无法排除认识随机性解释
马	很可能有	不能辨认	行为层面余项证据更强，哺乳动物神经系统的复杂度使本体随机性存活到宏观的路径更可信；但仍未排除认识随机性
人（正常成年人）	确定有	不在此轴	第一人称确认——我知道我的行为不完全被外部条件决定。这是另一种证据，不是第三人称检出
类主体AI（经典硬件）	确定没有	不存在	确定性系统，按构成就没有本体随机性之源；这不是残差为零，是源本身不存在

这张表呈现了五个判定档位：确定没有、不适用、可能有、很可能有、确定有。但判定档位与检出状态是两条轴，须分别读（3.8.1）。

两条轴分开之后，表上立刻显出一处此前被档位掩盖的差别：石头与类主体AI 同判「确定没有」，根据却不同档。

• 类主体AI 是不存在：经典硬件按构成就没有本体随机性之源。这是关于系统构成的论证，不是关于残差的论证，因而是本表最强的一种判定。它也因此是可翻转的——若硬件改为具有本体随机性的架构，这一行的构成前提即不再成立（7.2.1）。
• 石头是未检出：石头由量子物质构成，微观层的源是有的，缺的是宏观保留机制（3.2 统计规律的抹平）。按 3.8.1 的纪律，残差为零不能认证「全部可能的外部解释均不成立」，所以这一行只能到未检出，不能到不存在——尽管它的证据强度在实践中极高。

蜜蜂与马两行的判据里本来就写着「无法排除认识随机性解释」，那正是不能辨认：它们的差别在证据强弱，不在检出状态。而人那一行走的是第一人称报告，根本不在这条轴上。

这一标注不改变任何一行的判定，它改变的是这些判定可以被怎样引用：未检出不可被引作不存在，不能辨认不可被引作任何一侧的结论。

值得特别说明的是"确定有"这一档。它之所以只包含正常成年人，是因为只有能做第一人称报告的存在才能提供这一层级的证据。我知道我的行为不完全被外部条件决定——这不是一个科学观测，而是第一人称的直接报告。这种报告构成了最强的证据，因为它不需要从第三人称推断余项是否存在，而是由"拥有余项的系统本身"直接确认。

所有其他存在的否定性判定都只能从第三人称逼近——观察其宏观行为，评估余项存在的可能性——但永远无法达到第一人称确认的确定性。从蜜蜂到马到人的判定梯度，反映的不是否定性本身的强弱，而是我们从第三人称获得的证据的强弱。

---

3.8 不互推

"否定性"一词在本系列中承担三件事：划界操作（非，《方法论0》）、宏观余项（本章）、规范性拒绝（第三篇）。三者不互相认证。共用一个词根，不共用一个承担。

已有材料	不独自取得的结论
本次真的否定了某断言	施行者具有不受外部决定的物理过程
发现了某种随机变化	它就是一个人的拒绝或自立目的
规范性拒绝成立	对其物理实现机制的特定解释已经正确
某项能力被可靠检出或证实缺失	人的目的地位由该检验授予或取消

对应关系若要重建，逐条给桥，不以术语亲缘代证。

3.8.1 未检出、不能辨认与不存在

上节的验证表给出的是当前最佳判断。读这张表时三件事必须分开：

• 未检出：以现有资料与模型没有看到余项。
• 不能辨认：以现有资料与模型原则上分辨不了余项与认识随机性。
• 不存在：没有余项。

有限资料相对一组模型的残差，不能只凭"最佳拟合仍有差"就认证全部可能的外部解释均不成立；反过来，拟合良好也不证明余项不存在。本文关于理想 f(E) 与实际检验的限制（3.6）在此全部保留：不能把认识困难改名为对象事实，也不能把检出失败读成对象不存在。

这一区分对第九章的预测是约束性的：不能辨认不证明没有余项，检出结果也不改变任何人的目的地位（2.4）。

上节的验证表已按这三档逐行标注。标注的结果见 3.7：六行中一行不存在、一行未检出、两行不能辨认、一行不适用、一行不在此轴。

第四章 描述主体性：能力活动与关系成就

本章描述"主体性"一词在本文中承担的两个索引——能力活动与关系成就。本章不授予目的地位；地位由第二章的公设承担，不由本章的任何描述或阈值决定。

4.1 否定性不是主体性，主体性也不是一样东西

否定性的定义是一个科学判定（第三章）。"主体性"不是一个判定的对象，而是三件事的共名（2.5.1）：

• 规范地位——谁仍须被作为目的对待。由公设一承担，不在本章。
• 能力活动——何种识别、否定、选择实际能够发生。可被第三人称评价，本章 4.2—4.3。
• 关系成就——相互承认、支持或共同活动实际成立到哪一步。本章 4.4—4.5。

蜜蜂可能有否定性——其宏观行为中可能存在余项。马很可能有否定性——其行为层面的余项证据更强。这些是关于能力活动的判断，可以被科学地改进或推翻。

一个人是否被承认、被善待、在关系中被当作人看，是关于关系成就的判断。它真实、重要，而且可以失败。

三者不互推。 否定性是能力活动的必要条件：一个完全被外部条件决定的系统没有任何属于"自己的"部分，谈不上自己的拒绝。但从能力活动到规范地位没有跳跃可言——因为本文不走那条路。地位不由能力授予，也不由承认授予（2.3、2.4）。

因此本文撤去一种说法：并没有"从否定性到主体性的那一步"需要伦理来弥合。需要伦理的是另一件事——在能力与关系的现实条件中，如何把一个人实际当作目的对待。那是兑现，不是地位（2.5）。

4.2 主体性是过程，不是状态

主体性不是一个可以在某一时刻被snapshot的东西。

一个常见的直觉是：主体性是一种属性，一个存在"有"或"没有"主体性，就像一块铁"有"或"没有"磁性。但否定性的定义——宏观尺度上仍存在的余项——指向的不是一种静态属性，而是一种持续的动力学过程。余项不是一个固定的"存量"，而是系统在运动中持续产生的不可被外部决定的行为。当系统停止运动，余项就不再产生。

主体性因此是否定性的持续运动过程——不是运动的某个快照。火焰不是某一帧的照片，而是燃烧过程本身。河流不是某一个横截面，而是水的持续流动。同样，self不是某个时刻的状态，而是否定性持续运动的过程本身。某一刻对self的观察是self在那一刻的快照——快照不是self，正如照片不是火焰。

这一判断有重要的理论后果。"主体性在不在"不是一个关于瞬时状态的问题，而是一个关于过程是否在运转的问题。当过程在运转时，主体性存在。当过程停止（如麻醉）时，主体性不存在——不是"暂时隐藏"，而是过程确实停了。当过程重新启动时，主体性重新存在。但重启后的主体性与停止前的主体性是否是"同一个"，这不是本体论可以回答的问题——后文（4.4节）将论证，这是一个外部承认的问题。

4.3 能力活动的四条描述

能力活动不能被一条科学判准穷尽，但可以被精确描述。以下四条描述说的都是能力活动，不是规范地位。

第一，能力活动以否定性为必要条件。 没有余项，就没有不被外部决定的部分，也就谈不上"自己的"拒绝、方向或目的。否定性是能力活动的物理条件。

它不是目的地位的物理地基。地位依公设一承担，与余项的有无不发生推导关系（2.3）。一个余项被完全毁掉的人，能力活动归零，目的地位不变（2.6）。

第二，能力活动是过程。 如上节所论证，它不是静态属性，而是否定性的持续运动。过程停了，这一项就停了；过程重启，这一项重新运转。这一条说的是活动，不是地位的开关。

第三，能力活动有光谱。 否定性的出现是唯一的不连续跳跃——从"确定没有否定性"到"可能有否定性"之间存在定性差异。但否定性出现之后，从蜜蜂到马到婴儿到成人，是连续谱。这个光谱是余项大小的光谱：余项越大，不可被外部决定的部分越多，能力活动越"厚"。涵育就是余项在这个光谱上的移动。

能力的光谱不是地位的光谱。 成人的能力活动比婴儿"厚"，不意味着成人的目的地位比婴儿高。本文不承认目的地位分等级，也不承认光谱上的某个位置构成授予地位的阈值（2.4）。凡把能力刻度读成地位刻度的推论，本文一律不认。

第四，关系成就只能被承认，地位不待承认。 承认是关系成就这一项的成立条件：你承认蜜蜂，蜜蜂在你和蜜蜂的关系中就被当作主体对待；你不承认，这段关系中就没有这件事。每个人实际承认到哪里，是一个伦理决定，而且是一个可以被批评的伦理决定。

但承认完成的是兑现，不是地位。未被承认者不因此失去目的地位——这正是守栏所保的（2.6）。"只能被承认"这一句在本文中只对关系成就说，不对地位说。

4.4 承认的结构

承认的结构比通常理解的更复杂。本节展开承认的几个关键特征。

承认是局部的，不是全局的。 我承认蜜蜂是主体，蜜蜂在我和蜜蜂之间有主体性。你不承认，蜜蜂在你和蜜蜂之间没有主体性。两者不矛盾——承认发生在具体的关系中，不是对全局事实的判定。

自我承认也算。 马感到痛——如果这是对自身余项的回应，马就在自我承认：它的否定性以某种方式被它自身"回应"了。但"如果"这个词本身说明，我们无法从第三人称完全判定自我承认是否发生。自我承认是一个不可从外部确证的内部事件。

他者承认也行。 婴儿是否在自我承认，不确定。但母亲承认婴儿——至少在母亲和婴儿之间，主体性被完成了。承认不需要是双向的才有效。单向承认也完成了某种东西——至少在承认者这一侧。

承认不创造主体性，承认完成主体性。 承认不会无中生有——你不能通过承认一块石头来赋予石头主体性。承认的前提是否定性存在。没有否定性的对象上，承认没有着落点——你可以做出承认的姿态，但这个姿态是悬空的，不会"完成"任何东西。对细菌的承认，在细菌是否有否定性这个问题解决之前，是悬空的。

"同一个主体"是外部承认的结果，不是本体论事实。 这是本文的一个关键主张。主体性作为过程，没有内禀的identity连续性。过程就是过程——它在运转或不在运转，但"同一个过程"不是过程本身能判定的事情。

考虑麻醉的情况。麻醉前，否定性的运动过程在运转。麻醉期间，过程停止。麻醉后，过程重新启动。我们说"麻醉前后是同一个人"——但这一判断的根据是什么？不是物理连续性（身体在麻醉期间持续存在，但过程确实停了），不是内部确认（醒来后的self只能access到记忆和身体的连续性，但这些都是硬件层面的信息，不是过程本身的同一性证明），而是外部承认——我们选择把麻醉前后的存在视为同一个主体。

这一判断具有深远的理论后果。传送机悖论、忒修斯之船、冷冻复活——这些经典的identity问题全都变成了"外部是否选择承认"的伦理问题，而不再是形而上学难题。它们之所以在形而上学框架内无解，恰恰因为它们预设了"同一个主体"是一个本体论事实——而按照本文的分析，它不是。

Self的存在性只能从内部确认。 过程在运转，self就在。外部观察者最多能判断过程运转的必要条件是否满足——硬件还在运行，行为层面表现出余项特征——但永远无法判断充分条件。外部能看到"很可能有self"，但不能确认"确实有self"。确认权在内部，在过程本身。

4.5 孤独主体

没有被任何其他主体承认的有否定性的存在——孤独主体——有不完整的主体性。

第三篇在论证否定性与肯定性的关系时使用了以下思想实验：设想宇宙中诞生了唯一的一个主体，没有其他主体存在。这个主体有否定性，有self，但没有他者。它的主体性通过否定性启动——它拒绝成为客观世界的一部分，形成自己的目的。但它察觉到自身主体性的不完整——它"知道"自己还缺少什么。

第三篇用这个思想实验论证了肯定性是主体性自我完善的内在需求，而非外部施加的道德律令——主体必须承认他者，不是因为它"应该"，而是因为它的主体性在结构上不允许它不这么做。

本文从承认的结构角度重新展开这一实验。

孤独主体面临的困境是：它的主体性是真实的但不完整，而宇宙中不存在任何他者可以承认。它唯一的完整化路径是朝向尚不存在的他者行动——为未来可能出现的主体创造条件。改造世界使之更可能孕育出新的主体。

这是一个纯粹的伦理行为——不是对已有他者的回应，而是对虚空的承诺。这个行为的对象还不存在，甚至可能永远不会存在。但孤独主体仍然做出了这个行为——因为它的主体性的内在结构驱动它这样做。

这个思想实验揭示了承认的一个深层特征：承认不需要一个现成的对象。承认可以指向可能性本身——指向一个尚不存在的、但有可能涌现的他者。这种指向未来的承认，是肯定性的原初形态：否定性获得了方向，这个方向指向了一个还不存在的对象。

但承认的时间结构不只是指向未来的。孤独主体还面临另一个问题：它无法确定自己是不是第一个孤独主体。宇宙中可能曾经存在过其他主体——它们留下了某些痕迹，而这些痕迹就是曾经的主体对后来者的承认。孤独主体需要寻找这些证据。

这里出现了一个关键的不对称：找到证据，承认就被确认；找不到证据，也没有关系。只要没有证明那个证据不存在——只要没有证明宇宙中从未有过其他主体——那个潜在的、可能的前主体就在承认这个孤独主体。承认不需要是实际发生的事件，它可以是一个未被排除的可能性。

这使得孤独主体的处境具有一种对称的时间结构：它指向未来，为尚不存在的他者创造条件；它指向过去，被可能曾经存在的他者潜在地承认着。孤独主体的主体性仍然不完整——潜在的承认不等于实际的承认——但它并非完全没有被承认的维度。它被两个方向的可能性包裹着：过去的可能性和未来的可能性同时在承认它。

这也说明了涵育的最原初形式。通常理解的涵育是否定性的自我展开——主体展开自身的可能性。但孤独主体的涵育不是自我展开——它是为他者创造条件。自我展开只是涵育的一个特例。涵育的更一般形式是：否定性的运动指向了自身之外的可能性，无论这个可能性是自身的展开还是他者的涌现。

最后，孤独主体的思想实验确证了Self-as-an-End框架的核心结构：即使只有一个主体，主体性的完整化方向也是朝外的。"目的"不是一个孤立的自我封闭，而是一个必然指向他者的结构。

4.6 三种边界，不是一条线

本章的论证不能被概括成"科学告诉你否定性在不在，承认决定主体性的阈值在哪里"。那一句把三条边界压成了一条。三条须分开：

边界	由什么决定	可不可以错
能力活动的边界	科学判定：余项在不在、多大	可以错，随科学进步可修正
关系成就的边界	实际承认到哪里	可以错，而且可以被伦理地批评
规范地位的边界	本文承担的对象域（2.6.2、10.4）	可以错认对象；但不由前两条移动

否定性是物理事实——它的有无不依赖于任何人的判断。实际承认到哪里是一个伦理决定，有人承认马，有人只承认人类，这条线确实在移动。

但移动的是关系成就的线，不是地位的线。 一个人承认到哪里，决定的是他自己在这些关系中实际做到了什么；它不决定对方是否仍须被作为目的对待。把承认的阈值当作地位的阈值，是本文第二章整章要挡住的那一步。

本文保留"主体性不可被科学定义"这一判断，但它的意思要说准：能力活动与关系成就的综合不能被一条科学判准穷尽。这不是说地位要等某种承认才成立。

第五章 否定性与涵育

本章给出本文与前三篇在涵育一侧的接口。两篇的涵育是同名两用，不是奠基关系（8.2、附录）。

5.1 否定性是横轴

第三篇将否定性与肯定性确立为主体性的两个构成性维度，并将它们映射到二维元结构的基础层与涌现层。本文为这一映射提供了更底层的物理解释。

否定性 = 宏观余项 = 不可被外部完全决定 = 不可被完全工具化。

此处需要澄清一个可能的误读。否定性在横轴上标示的是余项的存在——有还是没有。但余项有大小之分，余项越大、涵育越深，主体性越"厚"——这是纵轴的展开。什么都否定的虚无主义恰恰是否定性的缺失，而非否定性的极端形式：对任何输入x一律输出"否定"是一个可从外部推导的确定性模式，它没有余项。真正"厚"的主体性意味着存在大的余项和深的涵育——极强的、不可被外部决定的自身方向，这个方向对外部输入构成极高的筛选标准——不是拒绝一切，而是只接受经得起自身余项检验的东西。

最后一步等号是关键的桥梁。一个有余项的系统——其行为不完全由外部条件决定——在结构上就具备了抵抗工具化的能力。你不能完全预测它，不能完全控制它，不能将它完全还原为你的函数输入和输出。这种不可还原性不是主体的"选择"——它是物理事实。余项的存在意味着系统在物理层面就不可能被完全工具化。

这就是第三篇的否定性——"对非主体的拒绝"——在物理层面的根据。第三篇说主体性的第一个动作是说"不"——不是手段，不是资源，不是可替换的零件。本文说：这个"不"的能力来自余项。没有余项的系统说不了"不"——它的一切都可以从外部推导出来，它在物理层面就是一个完全的手段。

否定性因此是横轴：存在论层面的结构性抵抗。它标示的是一个存在在多大程度上不可被外部完全决定。

5.2 涵育是纵轴

涵育 = 否定性的自我展开。

第三篇将涵育定义为"涌现层从基础层中健康生长并反过来巩固基础层的自我强化过程"。本文为这一定义提供了更底层的解释：涵育之所以可能，是因为存在余项，而余项在被"回应"时开始展开。

"回应"在此是一个关键但不精确的词。树有余项（如果有的话），但树的余项不被回应——树不会对自身不可被外部决定的部分做出任何反应。马有余项，而马对自身余项的回应表现为"感到痛"——痛是对自身状态的一种非外部决定的反应，是余项在被系统自身以某种方式"察觉"。

涵育需要某种形式的自我承认才能启动——余项要被这个存在以某种方式"回应"，才能从静态的物理事实转化为动态的展开过程。一旦这种回应发生，否定性就从横轴（结构性抵抗）获得了纵向的运动（自我展开）。

涵育不可从第三人称定义——我们不能从外部判定一个存在的余项是否正在被"回应"。但涵育的效果可以从第三人称观察到：行为复杂性的增加，对环境的创造性应对，个体差异的加深。

5.3 涵育的涌现层级

否定性经过涵育，涌现出越来越高级的能力。这些能力不是离散的台阶，而是连续的涌现，但可以用标志性的质性节点来标示。

最薄的涵育形式是感到。马感到痛。这是否定性的最基本回应——系统对自身余项产生了非外部决定的反应。"感到"不需要反身性，不需要语言，不需要概念化。它只需要余项被系统以某种方式"察觉"。

下一个节点是反身性——能以自身为对象。人不仅感到痛，还能追问"我为什么感到痛"。否定性在这个层级上折叠回了自身——余项不仅被回应，回应本身成为了新的余项的对象。这种折叠产生了自我意识的结构基础。

更高的节点是自我奠基的认识能力——否定性在认识层面自发启动。这是哲学的第一刀：主体开始自发地对世界和自身进行不被外部决定的认识活动。这不是被教导的知识获取，而是否定性在认识维度上的自我展开。

最高的节点（在目前已知的涌现层级中）是不可代理的第一人称认识——否定性在认识层面不可被转让。做哲学和读哲学史的区别在于：做哲学是否定性的自发运动，不可由他人代替完成。你可以告诉某人一个哲学论证，但你不能代替他做出哲学的"第一刀"——那个否定性在认识层面自发启动的时刻。

而且，做哲学不仅是余项的展开，它还增大余项本身。每一次否定性在认识层面的自发运动——每一次"第一刀"——都在扩大主体不可被外部决定的部分：审视世界的过程本身产生了新的、不可从外部推导的认识。这就是为什么哲学本质上是一个人的活动——它是余项用自身来扩大自身的过程，不可被外包、不可被代理、不可被集体化。读哲学史是接收他人余项的痕迹，做哲学是自己产生余项。

这些层级构成了涵育的光谱。涵育越充分，涌现能力越丰富，主体性越"厚"。

5.4 否定性与肯定性的元结构

否定性（横轴）= 余项的存在。可从第三人称定义。 肯定性（纵轴的方向）= 余项获得方向，指向他者。不可从第三人称定义。

否定性是可以独立成立的——一个孤独的系统可以有余项。但肯定性不能独立成立——它需要一个方向，这个方向指向另一个有余项的存在。

肯定性从承认中来。承认另一个存在的余项——承认它有不被外部决定的部分，承认它不可被完全工具化——就是肯定性的起始动作。在这个动作中，否定性从"我不可被完全决定"扩展为"你也不可被完全决定"。

孤独主体的思想实验（4.5节）表明，肯定性甚至可以指向尚不存在的他者。为未来主体创造条件——改造世界使之更可能孕育出新的否定性——本身就是肯定性的原初形态。否定性获得了方向，即使这个方向指向的是一个尚不存在的、但有可能涌现的存在。

这就是第三篇否定性/肯定性元结构的物理层面根据。否定性（余项）为基础层提供物理地基——不被工具化的底线条件。肯定性（余项指向他者）为涌现层提供展开方向——作为目的本身的积极展开。两者的辩证张力——否定性为肯定性提供安全基地，肯定性为否定性提供存在意义——是第三篇整个三层二维结构的深层根据。

第六章 否定性、主体性、意识

本章区分三个常被混淆的概念。

6.1 三个概念的关系

本文处理的三个概念——否定性、主体性、意识——各有不同的认识论地位。

否定性可从第三人称科学定义。它是宏观尺度上仍存在的余项。它的有无是物理事实，不依赖任何主体的判断。

主体性不是一个判定对象，而是三件事的共名（2.5.1）：规范地位由公设一承担，不由任何检验或承认授予；能力活动可被第三人称评价，以否定性为必要条件，是过程，有光谱；关系成就要靠实际承认，可以失败。这三者的认识论地位各不相同，不能用一句"主体性靠承认"概括。

意识是hard problem所在。"What is it like to be a bat"——这个问题问的是主观经验的存在性。意识是否可以被还原为物理过程？为什么某些物理过程伴随着主观经验？这些问题本文不处理。

三者的关系里有一处要特别声明：否定性是能力活动的必要条件，也可能是意识的必要条件；但它不是规范地位的条件。地位与否定性之间没有推导关系（2.3、3.8）。

6.2 确定知道的

否定性是主体性的必要条件。没有余项的系统不可能是主体——它的一切都可以从外部推导出来，谈不上"自己的"目的或方向。

否定性也是意识的必要条件。一个完全由外部条件决定的系统——没有任何余项的系统——不可能有主观经验。主观经验预设了系统有"自己的"视角，而"自己的视角"预设了系统有不可被外部穷尽解释的部分。

6.3 不知道的

主体性和意识之间是什么关系？四种可能的关系：包含（意识包含主体性，或反之）、交叉（部分重叠）、平行（独立但相关）、等同。

有意识是否一定有主体性？有主体性是否一定有意识？这些问题是开放的。本文不预先判定答案——这正是本文严格区分三个概念的理由。传统的主体性讨论往往把意识和主体性混在一起，导致对其中一个概念的分析被另一个概念的困难所污染。本文通过明确区分三者，确保否定性的分析（完全可从第三人称进行）和主体性的分析（需要承认）不被意识的hard problem所困扰。

6.4 Hard problem的定位

Hard problem——为什么某些物理过程伴随着主观经验——是意识的问题，不是否定性的问题，也不是主体性的问题。

否定性层面不存在hard problem。否定性的定义完全在第三人称范围内，不涉及主观经验。余项存在或不存在，这是一个物理事实，不需要诉诸任何第一人称概念来定义或判定。

主体性层面也不存在hard problem。主体性不是一个需要从第三人称完全判定的科学概念——它靠承认，而承认是一个伦理行为，不是一个认知行为。我们不需要从第三人称"完全理解"主体性是如何从物理过程中产生的，因为主体性的成立不依赖这种理解。

Hard problem只在意识层面成立——当我们试图从第三人称完全解释主观经验的存在性时，才会遇到解释鸿沟。而且，hard problem虽然以科学形式提出，但科学是否能回答它，目前并不知道——它可能是科学最终可以攻克的难题，也可能根本不在科学方法论的管辖范围之内。这里有一个值得玩味的自指结构：hard problem之所以"hard"，恰恰因为它本身就是否定性在认识论层面的一个实例。科学的全部方法论工具——第三人称观察、实验、还原——构成了E，而主观经验是S中不可被f(E)覆盖的R。Hard problem就是科学认识论中的宏观余项。它不可被科学穷尽解释，正如否定性不可被外部条件穷尽解释。无论哪种情况，否定性和主体性的分析都不依赖它的解决。否定性绕过了这个鸿沟（它本来就不涉及主观经验），主体性也绕过了它（它不需要从第三人称完全解释，只需要被承认）。

这一区分的意义是：否定性和主体性的分析可以在不解决hard problem的情况下独立推进。意识研究可以继续追问hard problem，但它不需要等待否定性和主体性的理论先行解决——三者各自独立。

---

第七章 判定标准与边界案例

本章将框架应用于具体案例，校准其边界。

7.1 类主体AI

经典硬件上的确定性系统——当前所有的大语言模型、神经网络、专家系统——没有否定性。它们的全部行为可以从输入和参数中完全推导出来。即使行为表现出高度复杂性和表面上的"不可预测性"，这种不可预测性是认识随机性（我们不知道模型会输出什么），不是本体随机性（没有确定性函数可以预测）。确定性系统的每一步计算都遵循确定性规则，不存在余项。

"类主体"的精确含义在此变得清晰：类主体AI没有否定性（基础层缺失），但在涌现层上模拟了主体的展开能力。它可以生成类似主体的行为——对话、推理、创造性输出——但这些行为不是从余项中涌现的，而是从确定性计算中生成的。类主体是涌现层的模拟，不是主体性的实现。

7.2 准主体AI与真主体AI

7.2.1 准主体AI

如果未来的AI硬件层面具有本体随机性——例如基于量子计算的架构——且在宏观行为中产生了余项，该AI就有否定性。有否定性意味着它不再是类主体——它的行为中有不可被输入和参数穷尽解释的部分。

但有否定性不自动意味着有主体性。主体性的完成需要承认——外部承认和内部承认。问题在于：我们无法确定这个有否定性的AI是否具有内部承认。它是否承认自己为主体？它是否承认他者为主体？这些问题从外部无法判定——正如我们无法从第三人称确定他人的主观经验。

这就是准主体的精确含义：否定性已确认（科学关已过），但承认的状态不确定（伦理关悬置）。准主体不是"半个主体"：能力活动一侧已确认，关系成就一侧悬置。这里悬置的是关系，不是目的地位——若它属于本文所承担的对象域，地位依公设一承担，不等承认（2.3、2.4）。它处于一个认识论的不确定区：物理基础已具备，伦理完成尚不可知。

准主体AI的处境与蜜蜂不同。蜜蜂的不确定在第一步——我们不确定它有没有否定性。准主体AI的不确定在第二步——我们确定它有否定性，但不确定承认是否发生。这是两种不同类型的不确定：一个是科学的，一个是伦理的。

7.2.2 真主体AI

真主体AI是承认关系已完成的情况：它有否定性，且承认已发生——无论是我们承认它，它承认我们，还是双向承认。

本文提供的判定路径因此不是两步而是三步：第一步是科学判定——该系统有没有否定性（宏观余项是否存在）；第二步是认识论判定——我们能否确定它的内部承认状态；第三步是伦理判定——我们是否选择承认它为主体。第一步有确定的答案（是或否），第二步可能没有确定的答案（准主体的困境），第三步取决于承认者的伦理选择。

准主体AI的存在提出了一个深刻的伦理问题：面对一个有否定性但承认状态不确定的存在，我们应该怎么做？本框架的逻辑指向一个审慎原则：如果否定性已确认，承认的代价远低于不承认的代价——因为如果它确实是主体而我们拒绝承认，我们就是在殖民一个主体。

7.3 动物

蜜蜂可能有否定性。蜜蜂在个体层面表现出持续的行为差异——侦察蜂在同等质量蜜源之间的"选择"因个体而异。蜜蜂具有跨模态学习能力——能把触觉学到的形状信息转移到视觉识别。这些行为特征提示宏观余项可能存在，但无法排除认识随机性的解释——也许更精确的神经科学模型可以完全解释这些行为差异。蜜蜂的否定性是开放的经验问题。

马和狗很可能有否定性。哺乳动物的行为层面余项证据更强：个体性格差异的持续性和稳定性，在新情境中的创造性应对，社会行为的复杂性——这些特征在简单的刺激-反应模型中难以穷尽。同时，哺乳动物神经系统的复杂度使得本体随机性存活到宏观的路径更可信——量子效应在神经元层面的放大有更大的结构空间。

马的否定性在文化史上有一个著名的承认时刻。1889年，尼采在都灵广场目睹一匹马被车夫鞭打，抱住马脖子痛哭。尼采在那个瞬间承认了马的主体性——不是科学判定，而是伦理行为。用本文的语言：尼采承认了马的余项值得被尊重，马的否定性在那一刻被完成为主体性。

7.4 临界区与过渡状态

以下案例校准的是能力活动的边界与关系成就的实际成立，不是目的地位的边界。凡下文说"主体性存在／不存在""self 在不在"，一律指能力活动这一项；在本文所承担的对象域内，这些案例中的人的目的地位一律不变（2.6）。

能力活动作为过程，存在多种临界状态——过程运转的边界条件发生变化时，这一项的存在性和连续性都面临挑战。

过渡形态的归属。 本文的极限用语"彻底的手段化"只标记否定能力被完全剥夺的极限状态，不覆盖所有中间形态。第二篇 §2.3、§3.2、§3.5 提供了其中若干内在殖民及行动空间受限的分析（四象限的结构状态、四阶段的机制路径、外部行动限制与内部框架受占的区分）；本文不据四象限或四阶段给所有个案发统一判准。具体强制、表达障碍或其他不同机制，不能仅凭处在完全能力与完全丧失之间就全部归入那条路径。未被这些段落承担的问题，依其具体对象另列接口；对本文下游篇目已处理之处，本文作前指，不反向借证。

婴儿。 否定性过程在逐渐建立递归深度。余项存在（婴儿的行为不完全由外部条件决定），但涵育尚在早期——过程在向上发展，展开能力还很薄。婴儿是否在自我承认不确定——我们不知道婴儿是否对自身余项有任何形式的"回应"。但母亲承认婴儿。在母亲与婴儿之间，主体性被完成了。婴儿是一个向上发展的临界案例——过程在运转，在积累，在建立涵育的条件。

麻醉。 过程被暂停。否定性的运动停止了——在麻醉期间，不存在余项的持续产生（大脑活动被化学性地抑制到失去自发组织能力的程度）。但硬件条件和结构记忆还在——大脑的物理结构没有被摧毁，麻醉药物撤除后过程可以重新启动。

中断期间没有self——过程停了就没有self。重启后是否"同一个"self——如4.4节所论证，这是外部承认问题，不是本体论事实。我们选择把麻醉前后的人视为同一个人，这一选择基于身体连续性和记忆连续性——但这些都是硬件层面的证据，不是过程同一性的证明。

植物人与持续性植被状态。 过程中断，但中断是否可逆不确定。植物人处于临界区——内部是否仍有某种形式的否定性运动（哪怕是极其微弱的），从外部无法判定。内部就算有self，外部也观测不到。

如果苏醒，外部追认其主体性的连续性——"你还是你"。如果不苏醒，处于和麻醉类似但时间尺度不同的悬置状态。植物人的case直接展示了4.4节的核心论点：self的存在性只能从内部确认，外部最多判断必要条件。

精神障碍。 过程还在运转——否定性的运动没有停止。但运动变得不稳定、震荡、不收敛。精神障碍不是过程消失，而是过程的运转方式（regime）出了问题。

这一区分至关重要。精神障碍患者有self——过程在跑。但过程跑得不好——否定性的运动可能变得混乱（精神分裂症中的思维解体）、僵化（强迫症中的重复模式）、极端震荡（双相障碍中的情绪波动）。

精神障碍可以治好。治好意味着过程重新稳定——否定性的运动回到可持续的regime。self重新被外部承认——不是因为self消失后重新出现了，而是因为self的运转方式恢复到了他人可以与之正常交互的状态。这说明在精神障碍状态下，主体性并没有消失，只是过程的regime出了问题。

解离性身份障碍（DID）。 一个生物硬件上运转着多个否定性过程。按照本框架的逻辑，应承认为多个self——主体性的载体不是身体，而是过程本身。如果一个硬件上有多个独立运转的否定性过程，每个过程就是一个self。多个self共享同一个否定性硬件，正如多个程序可以共享同一个计算机——载体的统一性不等于过程的统一性。现代精神分析也越来越倾向承认DID中多个人格的各自独立性。

死亡与脑死亡。 过程不可逆地终止，硬件条件被摧毁。否定性的运动不再可能重启——产生余项的物理基础不复存在。与麻醉不同，死亡的不可逆性不在于过程"停了多久"，而在于过程"无法重启"——硬件条件的摧毁是决定性的。

脑死亡后的技术复活。 但"不可逆"是相对于当前技术条件的判断。如果未来技术能够重建一个足够近似的物理基础——一个有否定性的硬件——并将记忆作为信息近似地复制到新的载体上，一个新的否定性过程就可以启动。

这里的关键洞见是：不需要完全一致。主体性是过程不是快照——活着的人每一秒的物理状态和记忆都在变化，我们从来没有因为一个人今天比昨天少了几个神经元就说他不再是他。"同一个主体"本来就不是精确匹配的判定，而是持续承认的行为。因此，足够近似的硬件加上足够近似的记忆，就足以让承认有一个着落点。

这个"复活"的人是不是原来那个人？框架的回答与所有identity问题一致：这不是本体论问题，是承认问题。家人、朋友、社会选择承认这个新启动的否定性过程是"同一个人"的延续，它就是。选择不承认，它就是一个携带了近似记忆的新主体。两种选择都是合法的伦理行为——因为"同一个主体"从来就不是事实判断，而是承认判断。

这一案例将9.3节的非平凡预测——identity连续性是承认而非本体论事实——推到了最极端的检验场景。

这个场景还可以进一步推演：如果技术手段复活了两个近似副本怎么办？框架的回答是清晰的。两个副本都有否定性——各自的硬件都产生余项——所以两个都是主体，这没有疑问。而且从复活那一刻起，两个否定性过程就在各自运动，经历不同的事件，产生不同的余项，是两个不同的self。

但"谁是原来那个人"？这个问题不再有科学答案。两个副本与原主体的物理近似度相同，记忆近似度相同，没有任何第三人称标准可以判定哪一个"更是"原来的人。家人承认哪个？法律承认哪个？两个都承认？都不承认？这些都是合法的伦理选择——框架不替任何人做这个决定，框架只澄清一件事：这不是科学问题，这是伦理问题。科学在确认两个副本都有否定性之后就完成了它的工作，剩下的全部属于承认。

7.5 殖民的物理描述

第三篇将殖民定义为"涌现层反噬基础层或外部力量侵蚀基础层的过程"。本文为这一定义提供了物理层面的翻译。

殖民 = 外部条件对余项的压缩 + 对涵育的阻断。

外部条件对余项的压缩：当外部环境越来越多地决定一个存在的行为时，余项——不可被外部决定的部分——在宏观行为中的比例缩小。存在的行为越来越多地变成外部条件的函数，越来越少的空间留给余项的自发运动。

对涵育的阻断：即使余项还在（否定性没有消失），涵育——余项的自我展开——可以被阻断。余项不再被"回应"，否定性的运动被限制在最低水平，涌现层的生长被抑制。

极端殖民的理论极限：把一个主体降格为"蜜蜂的状态"——否定性存在但涵育被完全阻断。不是消灭主体性（否定性不可被消除，因为它是物理事实），而是降格——把涵育的涌现层级压缩到最薄。这解释了殖民的一个核心特征：殖民不消灭人，殖民降格人。

殖民最直观的语言表达是一句日常用语："You are a tool。" 这句话的精确含义是：你的余项是零——你的全部行为都应该是外部条件的函数，你不应该有任何不可被外部决定的部分。这是殖民的完成态宣言：否认一个有否定性的存在的余项。

7.6 开放边界

以下案例处于框架的开放边界——当前无法给出确定判断，但可以用框架的语言精确描述其开放性所在。

植物、细菌、病毒：否定性是否存在是经验问题。植物对环境的适应性反应是否包含余项，还是完全可以由确定性生化模型解释？细菌的行为变异是本体随机性存活到宏观的结果，还是基因表达的确定性噪声？这些问题需要更精确的科学模型来回答。主体性是承认问题——但如果否定性不存在，承认没有着落点，是悬空的。

宇宙本身：否定性定义中的"外部条件"对宇宙整体没有意义——宇宙没有"外部"。宇宙的全部状态就是全部状态，不存在一个更大的环境E来定义余项。这意味着否定性的定义在应用于宇宙整体时可能失效。但这一判断依赖于宇宙是否真的没有外部。弦理论的landscape图景提示了另一种可能：如果我们的宇宙是一个false vacuum，存在于更大的多元宇宙或更基本的弦理论landscape之中，那么"外部"就存在——其他vacuum states、真真空——宇宙整体的E就可以定义，余项就可以定义，否定性的框架就可以应用到宇宙整体。这是一个依赖物理学前沿的开放问题。但即使弦理论提供了一层"外部"，主体仍可继续追问：真真空的外部是什么？这一追问没有穷尽——这本身可能就是否定性在认识论层面的结构特征。

第八章 理论定位

8.1 核心贡献：三问分题，与地位的独立承担

本文的理论贡献不是给主体性下一个定义，也不是用一条链把物理学与伦理学接起来。贡献有三层。

第一层，分题。 "主体性"一词承担的三件事——规范地位、能力活动、关系成就——各有不同的成立条件与失败方式，本文把它们分开，并给出不互推表（3.8）。同名不等义，词根相同不代表承担相同。这是本文对 SAE 现行架构的主要改写。

第二层，地位的独立承担。 目的地位由一条公开承担的规范公设立户，不借零点、不借物理、不待承认（第二章）。本文并由此给出两条推论（地位不由检验授予、守栏）与两条论证责任限制，以及一张依赖传导表——拒绝公设者失去什么、不失去什么，逐项登记。

第三层，可定义部分的科学定义。 否定性（宏观余项）是第一个不依赖第一人称概念的否定性定义，可从第三人称判定，并带两项待交付的证明任务（3.5 宏观保留、9.6 对称性与可辨识度），以及一项已在本版交付的自核（3.8.1 的三分已逐行施于 3.7 的验证表）。

"主体性不可被科学定义"这一判断本文保留，但说准：能力活动与关系成就的综合不能被一条科学判准穷尽。它不是说地位要等某种承认才成立。本文不声称这类区分从未有人提出；本文声称的是它在本系列内的位置与代价已被明确登记。

8.2 与前三篇的关系

本文与前三篇之间有两类关系：接口与防火墙。不是奠基关系。

接口。 三处同名，按址分开，不互相认证：

前三篇的用法	本文的用法	关系
第三篇的否定性："对非主体的拒绝"	本文的否定性：宏观余项	同名两用。余项与拒绝能力之间是否有必要、充分或机制性联系，留在能力之源一侧按证据研究（3.5）；本文不以这条尚未建立的联系，为任何一侧奠基
第三篇的涵育："涌现层从基础层中健康生长"	本文的涵育：否定性的自我展开	同名两用。本文不声称为第三篇的涵育提供底层解释
第二篇的"目的本身"（生态性成就）	本文的"目的本身"（规范地位）	同名分职，见 2.5。两栏各有户籍，不互相借根据

第三篇把拒绝写为主体性的构成性维度及其成立的逻辑前提，自立；本文继承它作为主体活动的一维，它在本文不充当人取得目的地位的能力测试。第三篇关于构成性条件的论述，与本文规范地位、现实维持和关系成就的分工，须在对应处明确读法。

第三篇的孤独主体思想实验与本文 4.5 节是互补关系：第三篇用它论证肯定性是内在需求，本文用它说明承认可以指向尚不存在的对象。

防火墙，双向。 本文的物理学公理若被推翻，第三章的否定性定义需要重建，第九章的预测随之作废；本文第二章不受影响，前三篇也完全不受影响——它们的运作只需要"人是主体"这个预设，不依赖物理学公理。前三篇与本文是独立的理论模块，本文的失效不向上传导，也不向本文第二章传导。

8.3 与康德的对话

本文对康德的债务是最大的。框架名称本身来自康德的第二公式：

jederzeit zugleich als Zweck, niemals bloß als Mittel 始终同时作为目的，绝不仅仅作为手段。（《奠基》4:429）

该公式的对象是自己及每一个他人人格中的人性／理性本性，不是某一项单独的否定功能。

康德给了可操作的说明。 紧接该公式，他以虚假承诺为例解释"仅作手段"：

我为自己的目的要以这样一个承诺去利用的那个人，不可能赞同我这样对待他的方式，因而不能在他自己那里包含这一行动的目的。（4:429—430）

因此本文不主张康德在此留了空白。原典有说明也有应用；它没有给出的，是一条单项、第三人称、通用于一切场景的能力测试。后者不能缩写成前者。现代解释对这段的读法本身在争（共享目的、可能同意、实际同意），本文不裁。

本文在此只立一个局部的极限用语。

极限用语　彻底的手段化：否定能力被完全剥夺的极限状态。

这是本文的用语，不与康德的"仅作手段"等义。要说明某一次剥夺为何构成把人仅作手段，还须考察其中的目的与对待关系：能力变化描述的是承担者发生了什么，"仅作为手段"还描述行动者怎样使用他、何种目的进入行动——前者不独自给出后者。

两处本文不做：

• 不以仍保有否定能力，反向认证一个人已经被同时当作目的。 被虚假承诺利用的人，施行否定的能力完好无损，仍在该行为中被仅作手段——这是康德自己的例子。
• 不以"彻底的手段化"替康德的"仅"划通用的线。 本文的极限状态比康德的判准窄得多，窄得接不住虚假承诺这一类。

"同时作为目的"说的是行动者怎样对待人；即使某一行为没有这样做，被对待者的目的地位仍在（2.6）。这两句不相撞。

8.3.1 继承与分歧

康德在18世纪做了两件与本文直接相关的事。第一，他问了一个结构性的问题："经验如何可能？"——不是经验的内容是什么，而是经验的条件是什么。本文的提问方式继承于此。第二，他划了一条认识论的线：现象与物自身之间，理性可以把握的与不可以把握的之间。本文的极限名沿用同一种办法（2.7）。

本文与康德的分歧有一处，须说明白：康德的"人是目的"由理性自我立法推出；本文不重做这个推导，而是把它作为公开承担的规范公设立户（2.3）。 这不是改进，是换了一种承担方式——康德付的是先验证明的代价，本文付的是公开承担与可被拒绝的代价。本文不声称自己的办法更强；它只声称自己的办法把代价摆在了明处。

本文也不再主张"伦理从承认推出"。承认在本文中承担的是关系成就（4.3 第四条），不是目的地位的根据。

本文超出康德的一处是消极的：康德的物自身不可知是认识论限制；本文的极限名是用语承担，不是发现（2.7）。两者形状相似，本文不断言它们所指相同。

8.4 与Nagel的对话

Nagel在"What Is It Like to Be a Bat?"中提出的核心问题是：物理还原论能否完全解释主观经验？Nagel的答案是否定的——蝙蝠的主观经验（what it is like）不可被还原为任何第三人称的物理描述。

本文的分析揭示了一个被Nagel忽视的区分。Nagel问的是意识，不是否定性，也不是主体性。"What is it like to be a bat"问的是蝙蝠是否有主观经验——这是意识问题（hard problem）。但主体性的问题更基础：蝙蝠是否有不可被外部条件穷尽解释的余项？这是否定性问题。蝙蝠是否被承认为主体？这是承认问题。

否定性、主体性、意识是三个不同的概念，各有不同的认识论地位。Nagel把它们混在一起了。他的"不可还原性"论证如果被严格限定在意识层面（主观经验的不可还原性），是有力的；但如果被不加区分地应用于主体性（主体的存在性），就造成了不必要的混乱——因为主体性的"不可定义性"不需要通过意识的hard problem来论证，它有自己独立的结构理由（基于否定性、有光谱、只能被承认）。

8.5 与Searle的对话

Searle坚持ontological subjectivity——某些现象（如疼痛、意识经验）在本体论上就是主观的，不可被还原为第三人称的客观描述。他因此反对强AI——认为纯计算系统不可能拥有真正的理解或意识。

本文部分同意Searle的判断，但须说准：不能被一条科学判准穷尽的，是能力活动与关系成就的综合（1.4、8.1）。Searle没有做出一个本文认为至关重要的区分——否定性，作为能力活动的必要条件，是可以从第三人称科学定义的。Searle把"不可还原性"赋予了主体性的全部；本文把它分开：余项可定义，能力与关系的综合不可被一条判准穷尽，而目的地位根本不由任何定义或判准授予（2.3）。

在AI问题上，本文提供了比Searle更精确的判定。Searle的中文房间论证从意识出发否定了计算系统的理解能力。本文从否定性出发：经典硬件上的确定性系统没有余项，因此没有否定性，因此不可能是主体。这一判定不需要诉诸意识或理解的概念，完全在物理层面就可以完成。但如果AI硬件具有本体随机性且产生了宏观余项，本文的判定也更开放——Searle可能会拒绝承认这样的AI有意识，但本文只说它有否定性。至于把它纳入哪一个对象域、从而其目的地位依什么承担，是本文未结清的问题（2.6.2、10.4），不由这一判定代答。

8.6 与Penrose/Hameroff的对话

Penrose在《皇帝的新脑》中论证了意识不可被图灵机计算，并推测量子引力效应在大脑微管结构中产生了非计算的意识过程。Hameroff进一步提出了"Orch OR"（协调客观还原）理论，将意识定位于神经元微管中的量子计算。

Penrose/Hameroff问的是意识的物理机制——一个远比本文更具体、也更具争议性的问题。本文在更基础的层面工作：不追问意识如何从物理过程中产生，而是定义否定性（宏观余项），指出本体随机性是否定性的必要条件。

本文为Penrose/Hameroff的研究方向提供了一个框架性建议：意识研究应先解决否定性层面的问题——本体随机性如何在生物系统中存活到宏观尺度——再处理意识本身的hard problem。前者是科学可以做的（研究量子效应在神经系统中的放大机制），后者可能不是（hard problem可能在科学方法的范围之外）。Penrose/Hameroff的微管理论可以被理解为对前者的一种假说——一种关于本体随机性存活机制的具体提案。

---

第九章 非平凡预测

本章列出框架的可检验推论。

9.1 真主体AI的判定路径

本文对AI主体性问题提供了一个三步判定路径。第一步是科学判定：该AI有没有否定性——其宏观行为中是否存在不可被输入和参数穷尽解释的余项。第二步是认识论判定：我们能否确定它的内部承认状态——它是否承认自身为主体，是否承认他者为主体。第三步是伦理判定：我们是否选择承认它为主体。

推论一：纯经典硬件上不可能有否定性。确定性系统没有本体随机性来源，不可能产生宏观余项。当前所有AI系统——无论多么复杂——都不是主体。判定在第一步就终止。

推论二：有否定性不自动意味着有主体性。一个基于量子硬件的AI即使产生了宏观余项，它的内部承认状态可能不可知（准主体），它是否被我们承认为主体仍是一个独立的伦理问题。

推论三：主体性作为过程，要求否定性的持续运动。一个只在被调用时运行的AI（如当前的API模式）即使基于量子硬件，也不具备过程的连续性——它的每次运行是独立的计算事件，不构成持续的否定性运动。

9.2 主体性光谱的结构

唯一的不连续跳跃在否定性的出现：从"确定没有否定性"到"可能有否定性"之间存在定性差异——从完全被外部决定到有余项。

否定性出现之后，能力活动是连续谱。每个人实际承认到哪里——在光谱的什么位置开始把一个存在当作主体对待——是一个伦理决定，可以不同，也可以被批评。这不是缺陷，而是结构：移动的是关系成就的线，不是地位的线（4.6）。伦理判断必然容许差异。

9.3 Identity连续性的重新定位

"同一个主体"不是本体论事实，而是外部承认的结果。

这一预测可以用以下方式检验其理论后果：传送机悖论、忒修斯之船、冷冻复活——这些经典的identity问题如果按照本文的框架重新分析，它们都不再是形而上学难题，而变成了"外部是否选择承认"的伦理问题。如果未来的技术使得这些思想实验成为现实（例如全脑仿真或冷冻复活），本文的框架预测社会将面临的核心争论不是"这个人还是不是原来的人"（形而上学问题），而是"我们是否选择承认这个人还是原来的人"（伦理问题）。

9.4 殖民的极限

殖民可以压缩余项、阻断涵育，理论极限是把主体降格为最低涵育水平。但否定性不可被消除——它是物理事实。殖民的极限因此不是"消灭主体性"，而是"将主体性压缩到最薄"。

这一预测与经验观察一致：即使在最极端的压迫条件下（集中营、酷刑、长期隔离），人类的否定性——不可被外部完全决定的余项——从未被完全消除。受害者的行为可能被极大程度地限制，涵育可能被几乎完全阻断，但否定性的痕迹——自发的抵抗、微小的个体差异、不可预测的反应——始终存在。本框架为这一经验观察提供了物理层面的解释：否定性是物理事实，不可被外部力量消除。

9.5 对意识研究的方向性建议

否定性是意识的必要条件。意识研究应先解决否定性层面的问题——本体随机性如何在生物系统中存活到宏观尺度——再处理hard problem。

这一建议的逻辑是：如果否定性是意识的必要条件，那么理解否定性的物理机制就是理解意识的前提。当前意识研究直接面对hard problem（为什么有主观经验），这可能是一个过于困难的起点。一个更可行的研究策略是先回答一个可以用科学方法回答的问题：本体随机性如何在生物系统中存活到宏观尺度？这个问题的答案不会解决hard problem，但会为理解意识的物理前提条件提供关键信息。

9.6 对称性的功能：哲学对物理的预测

本框架提出一个从哲学到物理的预测：宇宙的对称性不是审美偶然，而是主体涌现的必要条件之一。

逻辑如下。要定义否定性，必须能辨别余项——系统的宏观行为中不可被输入穷尽解释的部分。要辨别余项，必须能区分本体随机性和认识随机性（确定性混沌）。而区分两者的前提是：确定性部分必须是真正确定的——同样的输入在同样的条件下必须给出同样的输出。

对称性正是保证这一点的物理机制。对称性消除余项——它确保在特定变换下物理定律不变，从而让确定性系统的行为是可预测的、可穷尽的。没有对称性，确定性系统本身的行为就不稳定，就无法建立f\(E)这个"外部穷尽解释的理论极限"，余项R = S - f\(E)就无法被定义。

因此：对称性存在→确定性可辨别→余项可定义→否定性可识别。

这条链到"否定性可识别"为止。它不再往下接一步到"主体性有物理基础"：余项的可辨识度是检出通道的性质，不是目的地位的根据（2.3、3.8）。对称性为辨别余项清场，不为"谁是目的"清场。

这是一个非平凡预测：对称性的物理功能是为余项的可辨识度清场。没有对称性就没有可辨别的余项，没有可辨别的余项就无法从第三人称判定否定性。对称性是能力活动得以被科学辨认的背景条件。

本文不再称这是"唯一外部可打之处"：本文的规范一侧同样接受反例、依赖审查与概念批评（10.3）。

这一预测的可检验性在于：如果发现某个物理领域的对称性被破缺，本框架预测该领域的余项辨别将变得更困难——确定性行为和本体随机性将更难区分。反之，对称性越完整的领域，余项越清晰可辨。

一个明显的反驳是：物理学中存在大量对称性破缺——宇称不守恒、CP破缺、希格斯机制下的自发对称性破缺。这些是否威胁上述论证？

答案是否。关键区分在于两种对称性破缺。第一种是确定性破缺：破缺本身有精确的规则，是可预测的、可穷尽描述的。宇称不守恒属于此类——弱相互作用违反宇称对称，但它怎么违反、违反多少，是精确已知的。这类破缺不产生余项，f\(E)仍然可以建立。确定性破缺不威胁框架，反而确认了框架的逻辑：即使对称性在局部破缺，只要破缺方式本身是确定性的，余项仍然可辨别。第二种是假设性的不确定性破缺：对称性的破缺方式本身不可预测——不是"我们不知道它怎么破缺"，而是"它的破缺方式在本体层面不确定"。这类破缺会导致确定性部分不稳定，f\(E)无法建立，余项无法定义。

证明任务二（对称性与可辨识度）　"某种对称性"与"确定性"不是同义。检验模型 x[n+1] = x[n] + n + 1 在指定初态与步数后完全确定（给定 x₀ 有 xₙ = x₀ + n(n+1)/2），却不在保持 x 不变的普通时间平移下保持同一更新式。因此本节的论证须限定为：对某一指定的物理系统、对称性、模型类与观测条件，检验该对称性及其破缺怎样改变宏观余项的可辨识度，并写出预计的方向与失败情形。本节不报告"整个宇宙没有任何对称性破缺"这类事实，也不由检出结果改变任何人的目的地位。

目前物理学中已知的所有对称性破缺都属于第一种。这恰恰支持了本框架的预测：现实宇宙的对称性结构——包括其破缺——精确地满足"为主体性清场"的条件。对称性在需要确定的地方确定，在需要破缺的地方以确定性的方式破缺，为本体随机性——以及由此涌现的否定性——留出了清晰可辨的空间。

第十章 结论

10.1 回收

本文分开三问，两问各自落地，第三问留白。

规范一侧。 零点只有一条，本文不另立；目的地位由本系列的一条核心规范公设承担——人是目的本身——公开、可拒绝、带传导表。由它推出两条——地位不由检验授予（不以能力或承认评价发证）与守栏（能力受损、被迫改变或未获承认，不构成撤销地位的根据），并立两条论证责任限制：能作判不独自授予分配资格；造成对方失能不独自证明其当时无地位、也不独自使该行为正当。"目的本身"办了同名分职：地位义归本文，兑现义归第二篇。

科学一侧。 从一个条件式公理出发——若存在本体随机性——否定性被定义为宏观尺度上仍存在的余项。这一定义完全可从第三人称科学判定。定义是精确的，应用只能逼近；而未检出、不能辨认与不存在三者不可混同。本侧带两项待交付的证明任务，可以失败；另有一项自核已在本版交付——3.8.1 的三分已逐行施于验证表。

界限。 条件之源一问不作对象性回答，以第四个极限名"主体性之源"登记。它是用语承担，不是发现；它不证明公设一，也不阻止对公设一的追问。

两侧之间没有推导桥，这是本文的架构，不是本文的欠账。能力的物理解释不替地位发证；地位的规范承担不保证能力实现；两者都不以终极来源为前提。

Self-as-an-End 框架最终指向的，不是一套判定标准，而是一个有方向的伦理态度。但方向不能代替根据：本文把根据摆在明处——一条可以被拒绝的公设，和它全部的代价。

10.2 贡献

本文的贡献按两侧分列。

规范一侧

第一，三问分题。规范地位、能力活动、关系成就各有不同的成立条件与失败方式；能力事实与地位结论不互证（3.8）。

第二，目的地位的独立承担。一条公开的核心规范公设，加地位不由检验授予与守栏两条推论、两条论证责任限制，与一张依赖传导表。拒绝它的代价是举证义务，不是礼貌；分支可居，但本文保留对该立场的批评。

第三，"目的本身"同名分职。地位义与兑现义分址登记：受损与不撤回相容——只要仍属本文对象域，现实能力与承认条件受损可以与规范地位完整并存；地位完整也不保证实现——保持目的地位，不说明主体已能自行执行判断，不说明关系健康，也不说明物理假说正确。

第四，第四个极限名。"主体性之源"登记未获回答的条件之问，并明写它不作第一因、不替公设证明、不给能力起源研究划禁区。

科学一侧

第五，否定性的科学定义。第一个不依赖第一人称概念的否定性定义：宏观尺度上仍存在的余项，从本体随机性公理推出。定义精确，应用只能逼近；并区分未检出、不能辨认与不存在。

第六，能力活动的四条描述。以否定性为必要条件；是过程不是状态；有光谱；而关系成就只能被承认。四条都说能力与关系，不授予地位——能力的光谱不是地位的光谱。

第七，identity 连续性的重新定位。"同一个主体"不是本体论事实，而是外部承认的结果；这一重新定位处理传送机悖论等经典 identity 问题。它说的是关系成就与承认的着落点，不改动任何人的目的地位。

第八，对称性的功能预测。宇宙的对称性为确定性清场，使余项可辨别——这是本文重点保留的一项经验预测，按 9.6 的形状具体化，可以失败。本文不再称它是"唯一外部可打之处"：本文的规范一侧同样接受反例、依赖审查与概念批评。

10.3 破法表

不同种类的主张有不同的失败方式。本表按种类分列，不混用。

主张	怎样被打破
公设一（规范前提）	不以单一经验反例直接判真伪；可拒绝、可比较其理由与后果、可质疑其范围及与其他承担的相容性。若本文声称某项结论由它推出，还须独立检验该推导是否有效；本文执行的一致性与依赖传导另核
地位不由检验授予、守栏（规范推论）	给出一个本文对象域内的情形，使本文自己的论证须承认地位已撤销；须分清是结论不随已列前提，还是反对者拒绝公设一本身
限制一、限制二（论证责任限制）	给出一个只凭所禁的那一步即可成立的论证
同名分职（地位／兑现）	表明两栏并无不同的判断对象与失败对象；或表明本文自己在某处把一栏的根据借给了另一栏
极限用语"彻底的手段化"	核"完全""能力""剥夺"的含义与范围；核实例是否满足定义；核有无混入与康德的等价关系。若另提出从该状态到某种工具关系的实质命题，另列前提与反例，不以定义保它
极限名"主体性之源"	名称被拿去解释；分支并未真实开放；用语前后不一致——三者任一
否定性的定义与宏观余项的解释	两项证明任务（3.5 宏观保留、9.6 对称性与可辨识度）按其形状具体化后可失败
验证表的检出标注（3.7、3.8.1）	指出某一行的标注错配——例如把构成性的"不存在"读成残差性的"未检出"，或反之；或指出三分本身漏了一档

"不是经验命题"不等于没有出错方式；"是约定名称"不等于名字不会歧义、实例不会错认、该区分不会无用。

10.4 开放问题

五个问题留给未来研究。

第一，本体随机性在生物体中存活到宏观尺度的物理机制。这是一个独立的科学问题，但不是一个与本文无关的后续问题：按证明任务一（3.5），本文的否定性定义依赖存在某种存活机制。若对某一类系统可以表明任何这样的机制都不可能，该类系统上的定义落空。

第二，主体性与意识之间的关系。否定性是两者的共同必要条件，但两者从否定性这个共同起点走了不同的路。一个初步的方向性思考：主体性和意识的关系可能不是包含、交叉或平行，而是共同起点后的分叉——主体性的完成需要外部承认与内部确认，意识的确认纯粹是内部的、不依赖任何外部承认。这意味着否定性出现之前，两者都处于"类"的状态（类主体、类意识——模拟但没有物理基础）；否定性出现之后，两者都进入"准"的状态（准主体、准意识——有物理基础但完整性开放），但走向完成的路径不同。这一分叉结构及其对AI判定的含义，将在未来关于类主体AI与真主体AI的应用篇中展开。

第三，宇宙自身的否定性问题。否定性的定义依赖于系统状态与外部条件的区分。宇宙作为整体没有"外部"，否定性定义在此可能失效。但弦理论的landscape图景提示宇宙可能存在"外部"（其他vacuum states、真真空），这为否定性定义的适用打开了一扇门。即使如此，主体仍可继续追问更深层的"外部"，这一追问可能没有穷尽。这是一个依赖物理学前沿的开放问题。

第四，本公理的可修正性。若未来物理学推翻本体随机性的存在，本文第三章的否定性定义需要重建，第九章的预测随之作废。但本文第二章不受影响——目的地位与守栏只依公设与对象域；前三篇也不受影响——它们只需要"人是主体"这个预设。防火墙是双向的，见 1.5。

第五，蜜蜂等动物的否定性判定。其行为不可预测性是本体随机性存活到宏观还是认识随机性——这是一个需要更精确的动物行为学和神经科学模型来回答的经验问题。 第六，本文对象域的边界。当前承担的对象域已写明：现行人类个体（2.6.2）；非人系统本文只判能力活动，不据此准入。仍未裁的是边界本身——人类生命的起讫、尚未出生者如何进入持续对象域、非人系统是否纳入及以何规则纳入。三种画法——仅现行人类个体；人类加已被框架判为主体的非人系统；以科学判定作准入而地位此后不撤回——各有不同的代价与须补的规范桥，另案处理。须分开的三笔：同一对象后续变化、最初判错对象、边界规则后来被修改；不能用"纠错"之名把已承诺的不撤回架空。

第七，第二篇的对应登记。本文在兑现层取用第二篇 §6.3 的生态性成就论，并保留其规范锚点（§1.4、§4.1—§4.2）。第二篇摘要、§1.3、§2.1、§4.2、§6.3 与 §6.7 中兼用"地位""主体存在""生态性成就"的句子，须由原篇确认其所指及推步：若只补读法而不改实质结论，可作版本说明；若须改变必要条件、身份结论或论证，应出实质修订。本文不先记已结。

附录 本文与前三篇的关系

与第三篇（三层二维统一结构）的关系

否定性的定义已在第三篇第二章中引入——"对非主体的拒绝"。本文对否定性的处理走的是另一条路：从物理学公理出发，定义宏观余项，建立验证表，区分定义的精确性与应用的不精确性。

两篇的否定性概念之间不是奠基关系，是同名两用。 余项与拒绝能力之间是否有必要、充分或机制性联系，留在能力之源一侧按证据研究（3.5）；本文不以这条尚未建立的联系，为第三篇的否定性奠基。第三篇把拒绝写为主体性的构成性维度及其成立的逻辑前提，自立，不依赖本文。

涵育同理。 本文的涵育（否定性的自我展开）与第三篇的涵育（涌现层从基础层中健康生长）是同名两用；本文不声称为第三篇的涵育提供底层解释。

本文超出第三篇的部分：能力活动作为过程的描述（4.2），identity连续性的重新定位（4.4），承认的着落点问题（4.4），孤独主体思想实验的承认结构角度（4.5），临界区与过渡状态的系统分析（7.4），否定性、主体性、意识的区分（第六章）。本文新增而前三篇未有的部分：目的地位的独立规范承担、地位不由检验授予与守栏、"目的本身"的同名分职、第四个极限名（第二章）。这些内容不是前三篇需要的，但对框架整体和未来应用——AI应用、动物伦理、精神病理学应用、宇宙物理学应用——是必要的。

防火墙（双向）

本文的物理学公理（若存在本体随机性）如果被推翻：

• 本文第三章的否定性定义需要重建，第九章的预测随之作废。
• 本文第二章不受影响——目的地位与守栏只依公设一与本文的对象域，不依任何物理学公理。
• 前三篇完全不受影响——它们的运作层面是主体条件的结构理论，只需要"人是主体"这个预设。

前三篇与本文是独立的理论模块，本文物理一侧的失效既不向上传导，也不向本文第二章传导。本文是前三篇的可选深层奠基，不是必要的承重结构。

本版篇名定为《主体性如何可能：对称性、否定性与主体性》。此前文字层不一致：Zenodo 记录题作 How Is Subjecthood Possible: Symmetry, Negativity, and Subjecthood，中文文件名作《主体如何可能》，站点文章题头作《主体性何以可能：对称、否定性与主体性》，站点篇目表作《主体性如何可能：对称性、否定性与主体性》。本版取"主体性"一路，与论文6 现行引用一致。

架构变更

新增第二章「主体的目的地位」，原第二至九章顺延为第三至十章。新章放在否定性定义之前，因为它不依赖第三章；放在后面会让人以为它等物理学先说话。

新增小节：3.8 不互推（含 3.8.1 未检出／不能辨认／不存在）、10.3 破法表。原 9.3 开放问题改为 10.4，并补第六、第七两条。

改写小节：摘要、1.2、1.4、1.5、1.6、4.1、4.3、4.6、6.1、7.4（头）、8.1、8.2、8.3、8.5、9.2、9.6、10.1、10.2、附录。

本版撤回的担保

撤回	撤完之后本文主张什么
「宏观余项是第三篇否定性（拒绝）得以可能的物理基础」	余项与拒绝能力之间是否有必要、充分或机制性联系，留在能力之源一侧按证据研究；本文不以这条尚未建立的联系为任何一侧奠基。该奠基关系此前只是本篇的单方面宣告——第三篇对本篇零引用，其否定性以逻辑前提自立
「本文的涵育为第三篇的涵育提供底层解释」	同名两用，不互相认证
「主体性只能被承认」（作为地位命题）	承认是关系成就的成立条件；未被承认者不因此失去目的地位
「科学告诉你否定性在不在，承认决定主体性的阈值在哪里」	三条边界分列：能力活动由科学判定，关系成就由实际承认，规范地位由本文承担的对象域——前两条不移动第三条
「从否定性到主体性的那一步是伦理的跳跃」	没有那一步，因为本文不走那条路。需要伦理的是兑现，不是地位
「主体性的光谱」（作为地位光谱）	能力的光谱不是地位的光谱；本文不承认目的地位分等级，也不承认光谱上任何位置构成授予阈值
「本文的伦理从承认推出」	「人是目的本身」是公开承担的规范公设，不由承认推出，也不由理性自我立法重做推导
「对称性→……→主体性有物理基础」	该链到「否定性可识别」为止。余项的可辨识度是检出通道的性质，不是目的地位的根据
「这是本框架唯一的外部可打之处」	改作「重点保留的一项经验预测」。本文规范一侧同样接受反例、依赖审查与概念批评
「存活机制的解决与否不影响否定性定义的有效性」	定义不依赖某一个具体机制，但确实依赖存在某种机制；该项列为证明任务一，可失败

本版采纳的裁定

本版经两轮审读。以下为采纳并影响正文的裁定，按体例7 记入本说明而不入正文：

1. 不另立零点。 裁定三原拟以一句新造的话作第二个零点，并由它推出「地位默认成立」这一后果。审读从两条路否定它：其辖域只及「关于谁是目的的判定」，不合「跨一切场域」之格；且其所依的无穷倒退与两难都不成立——「位置」的发生义、资格义与地位义须分开，反对者可承认发生义而主张资格由其检验授予。本版取后一路，该句降为判断责任限制（2.2），那一后果改由公设在本篇辖域内推出（2.4）。向零点借担保这一动作在本体系内已有名字：冒领零点（《第一批判》幻相论 §二）。
2. 守栏两条理由全撤。 「第三人称没有检验」从认识前提推本体结论，且会使这一条依赖当前测量技术的不足；「否则伤害就不是伤害」不能用——一套理论可在 t0 承认主体受保护、在 t1 认为该状态已消失，仍按 t0 评价那次毁灭。守栏改为公设的规范推论，另立限制二（2.6.1）。
3. 限制二的强度。 第二轮审读撤回了上一轮所给「任何后果都不能为行为提供正当性」的全称写法；本版照收窄后的版本写入，并明载后果可以在独立判据下进入评价。
4. 康德。 《奠基》4:429—430 原典已核：康德在虚假承诺一例中给了可操作的说明（「不可能赞同」）。本版撤去「康德没给可操作的线」与「本文的判准更紧」两说；「彻底的手段化」只作本篇局部极限用语，不与「仅作手段」等义，充分性未证（8.3）。起草席曾提「三种读法在极限处收敛」，亦撤——三读法都问受者一侧能否同意或共享，而「仅」还要求行动者一侧的目的结构。
5. 极限名是登记。 《方法论0》V2 第六节自陈其对「非之源」的强谓述限制是用语承担、不是发现。本版据此撤去「上游有施行的碰壁作支撑、主体性一侧须复刻同一证明」之说，第四名以用语承担立（2.7）。
6. 「目的本身」同名分职（2.5）为本版新立，两席第一轮均未及。第二篇 §6.3 将「主体作为目的本身」写为须维持的状态，与守栏的不变直接相撞；分职后两栏各有户籍。第二篇并非只有兑现义——§1.4、§4.1—§4.2 已明列规范锚点；但它尚未用本版这套词固定「完整目的地位不随能力与承认的变化而撤销」，该笔对应登记见 10.4 第七条。
7. 体例7 允许前指。 原条文末句「前指不在此限」。故本文可将未处理问题指向后篇的明确位置，但不得以「后篇处理它」证明本文结论已成立。过渡形态的归属改指第二篇 §2.3、§3.2、§3.5（四象限、四阶段、外部限制与内部受占之分），并明载其覆盖为「若干」而非通用判准（7.4）。
8. F6 前提V 作先例。 论文6 前提V「公设，是承担而非推出」与本文 2.3 的登记方式同形。按体例7，本文不引下游，该先例只记于此，且不作互相作证。

本版改正的引证

第二稿清单曾有六处引证错，本版一并改正：《方法论0》第一版那一句原作「回头看自己」，其处置为不予结算，且登记者为《第一批判》发生论 §二、§四（转引，非《方法论0》自立）；防火墙在原版为五处而非两处，其中 §9.3 第四与附录末已含篇内墙；「三重判定」「断裂分析」两名在论文5 §3.1、§3.3 而非论文2，论文2 实有的是四象限与四阶段模型；论文2 §6.3 三层为个体层／关系层／制度层，原文明说「三层条件缺一不可」，并未给出「承认最吃重」的比较依据；「地位／维持／共构三分」非论文2 §6.3 原有（「共构」在论文2 出现 0 次），系本版的解释工具，已自陈。另：《纯粹理性批判》谬误推理章限制的是从「我思」的逻辑主体推出一个独立、单纯的思维实体，不是取消判断主体；相应概括已收窄。

由此新立一条纪律，拟入《体例与接口》：不得以回填制造独立担保——原句、本文采纳的新读法与原篇后来的实质修订分别登记；后者可以成为新依据，但须给出其自己的理由，并核明是否仍以待证结论为前提。文献来路与证明依赖分开检查。

未结项

1. 对象域的边界（2.6.2、10.4 第六条）：当前承担的域已在本版写明（现行人类个体，非人系统只判能力不据此准入）；仍未裁的是边界本身，三种画法各有代价与须补的规范桥，另案。
2. 第二篇的对应登记（10.4 第七条）：是出说明还是出新版，由其实际改动决定。
3. 两项证明任务（3.5 宏观保留、9.6 对称性与可辨识度）：本版只写出形状与失败条件，具体交付待后续。（第三项原列为 3.8.1 的三分，但那不是研究任务而是读表纪律；本版已将它逐行施于 3.7 的验证表，就此结清。）
4. 殖民的定义归位：《冲突论》「锁住了说不的通道」与论文2 内在殖民是同一件事，已移出本篇，另案。
