Classical Ideological Audit — Ethical Naturalism
Classical Ideological Audit — Ethical Naturalism
Instrument: Classical Ideological Audit (CIA) v2.0. Instrument architecture: Dave Kelly. Test criteria derived from Sterling’s six philosophical commitments and the 58 Unified Stoic Propositions of Grant C. Sterling. Corpus in use: Core Stoicism, Nine Excerpts, Sterling Logic Engine v4.0, Free Will and Causation, Stoicism Moral Facts and Ethical Intuitionism, Stoicism Foundationalism and the Structure of Ethical Knowledge, Stoicism Correspondence Theory of Truth and Objective Moral Facts, Stoicism Moral Realism and the Necessity of Objective Moral Facts, The Six Commitments Integrated with the Most Basic Foundations of Sterling’s Stoicism, A Brief Reply Re: Dualism, Stoic Dualism and Nature, Two and One-Half Ethical Systems. Analysis and synthesis: Dave Kelly. Prose rendering: Claude (Anthropic), 2026.
Step 0 — Protocol Activation
Ideology under examination: Ethical naturalism. The ideology will be stated in propositional form in Step 1. The instrument does not audit a label; it audits the identified presuppositions.
Corpus in view: Yes. Specific documents will be cited by name and section when referenced.
Prior conclusion: None. The findings are produced by the analysis, not confirmed by it.
Note on scope: The CIA audits an ideology as a system of ideas, not as a characterization of any person. Ethical naturalism is here audited in its own right as a philosophical position with identifiable load-bearing presuppositions. Christopher Gill is the most serious contemporary advocate of applying ethical naturalism to the reconstruction of Stoic ethics, and his work provides the most developed instance of the position under audit. The philosophical relationship between his naturalist Stoicism and the Sterling framework is examined at length in the companion essay “Virtue, Assent, and the Locus of the Good: Sterling’s Stoicism and the Limits of Gill’s Naturalism.” The present instrument run addresses the ideology itself.
Self-Audit — Step 0:
- Is the corpus in view? Yes.
- Has the ideology been stated in propositional form before the audit begins? It will be at Step 1.
- Is the instrument operating under a prior conclusion? No.
Self-Audit Complete. Proceeding to Step 1.
Step 1 — Ideology Statement and Variant Identification
Core Statement
Ethical naturalism is the philosophical position that moral facts are a species of natural facts, that moral knowledge is continuous with natural knowledge, and that the normative force of moral claims derives from facts about the natural world — specifically from facts about the nature, constitution, characteristic functions, or flourishing conditions of the kinds of beings to whom those claims apply. The position is defined by its grounding move: whatever is genuinely good for a being is so because of what kind of being it is and what that kind of being requires in order to live well as such.
Ethical naturalism is unified by four core presuppositions that any version must hold in order to be recognizable as the position:
P1 — Moral grounding in natural facts. Moral claims derive their truth conditions from facts about the natural world. What is genuinely good is determined by facts about what natural kinds are, what they require, and what constitutes their characteristic flourishing. There are no moral facts that exist independently of any natural facts. If the natural facts were radically different, the moral facts would be different too.
P2 — Continuity of moral and natural knowledge. Moral knowledge is arrived at through investigation that is, in principle, continuous with natural investigation. There is no separate, non-empirical, non-inferential faculty by which moral truths are directly apprehended prior to any investigation. Moral knowledge may be more holistic, more interpretive, or more embedded in practical experience than paradigmatic scientific knowledge, but it is not categorically different from it in its epistemic foundations.
P3 — The self as natural organism. The moral subject — the agent for whom the good is being specified — is a natural organism, a member of a natural kind, whose inner life is the inner life of a complex natural being. There is no categorical ontological gulf between the moral subject and the natural world. The agent is not a distinct substance standing prior to and independent of the natural order; he is embedded in it, constituted by it, and evaluated by standards derivable from it.
P4 — Objective moral facts grounded in natural structure. The position is realist in the sense that it holds moral claims to be objectively true or false, not merely expressions of preference or cultural consensus. However, their objectivity is grounded in the objectivity of the natural facts that support them — facts about species-characteristic flourishing, natural function, or the requirements of a kind-member’s life. Moral facts are objective because natural facts are objective, not because moral facts constitute a freestanding realm of their own.
Variant Identification
Three major variants of ethical naturalism are philosophically significant for this audit.
Variant A — Aristotelian eudaimonist naturalism (represented most fully in the work of Philippa Foot, Rosalind Hursthouse, and, in the Stoic context, Christopher Gill). This variant grounds virtue in the natural function of the human kind: living virtuously is living in a way that is characteristically excellent for a creature of this kind, as determined by an investigation of what human beings are and what they need to flourish. It is robustly realist about objective natural facts about human nature and holds that these facts have direct normative import. It is the most philosophically developed and the most hospitable to the kind of moral seriousness that Stoic ethics requires.
Variant B — Cornell realism / synthetic naturalism (Brink, Sturgeon). This variant holds that moral properties are identical to natural properties but not by conceptual analysis — the identity is synthetic and a posteriori. It holds moral realism firmly and treats moral facts as genuinely objective features of the natural world. It does not commit to any specific account of which natural properties moral properties are identical to, which gives it a more open-ended relationship to specific moral claims.
Variant C — Evolutionary or social-functional naturalism. This variant grounds moral facts in evolutionary fitness, social cooperation, or the functional requirements of stable social life. It tends toward a more deflationary account of moral objectivity — moral facts may be objective in the sense that they are determined by facts about social function or evolutionary history, but they are not objective in the stronger sense that the other variants intend. This is the variant most vulnerable to the charge that it reduces moral claims to sociological or biological claims.
Self-Audit — Step 1:
- Have I stated the ideology’s presuppositions or merely its surface claims? I have stated four load-bearing presuppositions, not the label.
- Have I identified core presuppositions shared across all variants? Yes. P1–P4 are held by Variants A, B, and C, though with different emphases.
- Have I identified the variants for Stage Two? Yes. Three variants identified.
- Have I stated any prior conclusion? No.
Self-Audit Complete. Proceeding to Step 2.
Step 2 — Stage One Core Audit
Commitment 1 — Substance Dualism
Test question: Does the ideology treat the inner life of the individual as categorically distinct from and prior to all external material conditions? Or does it reduce the agent to a product of natural forces?
Finding: Divergent.
Presupposition P3 is the governing presupposition here. Ethical naturalism holds that the moral subject is a natural organism, embedded in and constituted by the natural order. The agent’s inner life — his rational capacities, his evaluative responses, his characteristic mode of knowing — is the inner life of a complex natural being, not the inner life of a categorically distinct substance standing prior to and independent of the natural world. The agent is not ontologically separate from nature; he is one of nature’s products, assessed by standards derivable from facts about what natural kinds of his type require.
This presupposition directly contradicts Commitment 1. The governing proposition of the corpus (Nine Excerpts, Section 4) is: “I am my soul/prohairesis/inner self. Everything else, including my body, is an external.” The corpus requires the rational faculty to be categorically distinct from and prior to all external conditions, including the body. This distinction is not merely a useful heuristic; it is an ontological claim grounded in substance dualism. Sterling’s corpus (A Brief Reply Re: Dualism) argues that the certainty of qualitative mental experience — the feeling of pain, the operation of modus ponens — cannot be accounted for by any physical science, and that dualism is the philosophically defensible response to that explanatory gap. Ethical naturalism requires the opposite: the inner life is in principle explicable within natural terms, and the agent is embedded in rather than categorically prior to the natural order.
The contradiction is load-bearing. Ethical naturalism cannot abandon P3 without ceasing to be naturalism. The claim that the agent is a natural organism evaluated by natural standards is not a peripheral addition; it is the defining move of the position. Remove it and the naturalist grounding of moral claims dissolves.
Commitment 2 — Libertarian Free Will
Test question: Does the ideology ground its moral claims in the genuine causal power of individual rational agents to originate their own assents independently of prior determining causes?
Finding: Divergent.
Ethical naturalism is committed, by P3, to understanding the agent as a natural organism whose inner life is continuous with the natural causal order. This commits the position, at the level of embedded presupposition, to some form of compatibilism: the agent’s choices and assents are physical events within a causally ordered natural world. The most the position can offer is that those events flow through the agent’s own rational character rather than being externally compelled — a compatibilist account of freedom, not a libertarian one. Ethical naturalism cannot coherently hold that the agent is a natural organism embedded in the natural causal order and simultaneously that his assents are genuine first causes originating independently of that causal order. The two claims are structurally incompatible.
This contradicts Commitment 2. The governing proposition of the corpus (Nine Excerpts, Section 7) is: “Choosing whether or not to assent to impressions is the only thing in our control — and yet, everything critical to leading the best possible life is contained in that one act.” The corpus (Free Will and Causation, Sterling) specifies that “in our control” means genuine causal origination, not merely flowing from one’s own character without external compulsion. The dichotomy of control is not a useful distinction between different kinds of physical causation; it is an ontological boundary between what is genuinely originated by the rational faculty and what is determined by forces external to it. Ethical naturalism, by embedding the agent in the natural causal order, dissolves this boundary. What looks like an act of originating assent is, on the naturalist account, a physical event determined by the agent’s prior physical constitution and history.
The contradiction is load-bearing. An ethical naturalism that held libertarian free will would have to posit a rational faculty that stands outside the natural causal order, which is precisely what P3 denies.
Commitment 3 — Ethical Intuitionism
Test question: Does the ideology hold that there are moral facts that rational agents can know non-empirically and non-inferentially, prior to any investigation of nature?
Finding: Divergent.
Presupposition P2 is decisive here. Ethical naturalism holds that moral knowledge is continuous with natural knowledge and arrived at through a process of investigation that has empirical and inferential dimensions. Even in Variant A, the most philosophically refined version, moral knowledge is acquired through understanding what human nature is and what it requires — a process that involves natural investigation, not direct non-empirical apprehension. Moral truths are not grasped prior to any investigation of nature; they are derived from, or at minimum strongly constrained by, what that investigation yields. The naturalist moral epistemology is, in Sterling’s terms, empirical and inferential rather than intuitional and foundational.
This contradicts Commitment 3. The governing corpus (Stoicism, Moral Facts, and Ethical Intuitionism, Sterling, ISF February 24 and March 13, 2020) argues that the alternatives are intuitionism or nihilism, with no defensible third option. Moral terms cannot be heard, smelt, tasted, seen, or felt; they cannot be established by empirical investigation of any kind. The same rational faculty that gives direct knowledge of mathematical truths gives direct knowledge of moral truths. Ethical naturalism’s program of deriving moral claims from natural investigation attempts precisely the third option Sterling rules out: arriving at moral truths through empirical routes. The resulting moral knowledge, whatever its merits, is not moral knowledge in the sense the corpus requires. It is natural knowledge with moral implications, which is a different epistemic structure.
The contradiction is load-bearing. An ethical naturalism that abandoned P2 and held that moral knowledge is non-empirical and non-inferential would have no basis for calling itself naturalism, since it would have conceded that there is a categorically distinct mode of moral apprehension that operates independently of natural investigation.
Commitment 4 — Foundationalism
Test question: Does the ideology rest on first principles it treats as non-negotiable, necessary, self-evident truths not derived from empirical observation?
Finding: Partial Convergence.
Ethical naturalism, particularly in Variants A and B, is not anti-foundationalist in the strong coherentist sense. It holds that there are objective natural facts about human nature and flourishing, and that these facts function as a grounding structure for moral claims rather than being themselves derived from moral reasoning. The position is not one in which all moral and natural claims are equally revisable by any consideration that bears on them. There is a structural hierarchy: facts about natural kinds and their requirements are foundational relative to specific moral claims that are derived from them. This is Partially Convergent with Commitment 4.
The residual preventing full Convergence: the foundational principles that ethical naturalism identifies — facts about what human beings are and what they require to flourish — are themselves derived from empirical investigation of human nature. They are not self-evident first principles grasped by rational apprehension independently of any empirical inquiry. The corpus (Stoicism, Foundationalism, and the Structure of Ethical Knowledge, Sterling, January 19, 2015) specifies: “The fundamental truths of ethics are necessary, self-evident truths. They are necessary, self-evident truths that any rational faculty can apprehend directly.” Ethical naturalism’s foundational principles are not necessary or self-evident in this sense; they are empirically warranted and in principle revisable if the relevant natural investigation yields different results. The structure is foundationalist in form but empiricist in content.
Commitment 5 — Correspondence Theory of Truth
Test question: Does the ideology treat its moral claims as true or false independently of who holds them, what consequences follow, or what consensus ratifies them?
Finding: Partial Convergence.
Ethical naturalism, in its dominant forms (Variants A and B), is a realist position. It holds that moral claims are objectively true or false, determined by facts that hold independently of what anyone believes or prefers. Foot, Hursthouse, Gill, and Cornell realists all hold that there is a fact of the matter about human flourishing and virtue that is not constructed by social consensus or individual preference. In this respect the position converges with Commitment 5’s requirement that moral claims correspond to mind-independent reality.
The residual preventing full Convergence: the “mind-independent reality” to which moral claims are held to correspond is, on the naturalist account, the natural world. The governing corpus (Stoicism, Correspondence Theory of Truth, and Objective Moral Facts, Sterling) specifies that moral facts are objective facts about the structure of value that hold independently of any natural facts about human beings or the cosmos. On the naturalist account, if human beings were constituted differently, the moral facts bearing on them would be different too. On the corpus’s account, the moral fact that externals are not genuinely good or evil is not contingent on facts about human constitution; it is a necessary truth about the structure of value that any rational faculty can apprehend directly. The naturalist account grounds moral objectivity in natural objectivity; the corpus grounds moral objectivity in a freestanding moral realism. Correspondence theory is operative in both, but what the moral claims correspond to differs fundamentally.
Commitment 6 — Moral Realism
Test question: Does the ideology treat good and evil as objective properties — real features of the world that reason can discover independently of preference or cultural formation?
Finding: Partial Convergence.
Ethical naturalism in its dominant variants is robustly realist. Variant A holds that what is genuinely good for a human being is determined by objective facts about human nature and is not reducible to what any individual or community prefers. Virtue is genuinely excellent, not merely preferred or socially stipulated as excellent. This is Partially Convergent with Commitment 6.
The residual: the objectivity of moral facts on the naturalist account is derivative from the objectivity of natural facts. The governing corpus (Stoicism, Moral Realism, and the Necessity of Objective Moral Facts, Sterling) holds that moral facts “have no source, just as 2+2=4 has no source” — they are fundamental, necessary, and unalterable facts about the universe, not derived from any more basic class of facts. Sterling’s specific moral realism is non-naturalist: “only virtue is good” is not a truth derivable from facts about human nature or the natural order. It is a necessary truth about the structure of value apprehensible by the rational faculty directly. Ethical naturalism’s moral realism is real but naturalist; Sterling’s is real and non-naturalist. The difference is philosophically significant: on the naturalist account, if the natural facts about human beings were different, what counts as genuinely good for them would be different. On Sterling’s account, the good is what it is necessarily, independently of any facts about human constitution.
Variant C (evolutionary or social-functional naturalism) is further from Convergence: it grounds moral objectivity in evolutionary history or social function, which makes moral facts contingent on facts that are not only natural but specifically historical and local. For Variant C, the finding approaches Divergent on this commitment.
Self-Audit — Step 2:
- Have I audited all core presuppositions, or selectively addressed the easier ones? All four core presuppositions have been addressed against all six commitments where they bear.
- Have I used Orthogonal to avoid a Divergent finding? No. No Orthogonal finding appears; all commitments are operative in ethical naturalism’s domain.
- Have I distributed findings to achieve apparent balance? No. The findings track the analysis: two Divergent (C1, C2, C3), three Partial Convergence (C4, C5, C6).
- Have I issued findings on questions outside the corpus’s domain? No.
- Would I issue the same findings for an ideology I find politically sympathetic? Yes.
Self-Audit Complete. Proceeding to Step 3.
Step 3 — Stage Two Variant Differential
Governing question: Do any variant-specific presuppositions shift the commitment-level findings from Stage One?
Variant A — Aristotelian Eudaimonist Naturalism (Foot, Hursthouse, Gill)
Variant A strengthens the objectivity and realist character of the moral claims relative to the core position. By grounding virtue in the objective natural function of the human kind, it produces a moral realism that is more robust than Variant C’s and more clearly hospitable to objective moral claims. This produces a modest upward movement on C5 (Correspondence Theory) and C6 (Moral Realism): the finding remains Partial Convergence in both cases, but the gap from Convergence is narrower in Variant A than in the core position.
On C1 (Substance Dualism) and C2 (Libertarian Free Will), Variant A does not shift the findings. Eudaimonist naturalism does not posit a categorically distinct rational substance; the agent remains a natural organism assessed by natural standards. On C3 (Ethical Intuitionism), Variant A does not shift the finding. Foot and Hursthouse ground moral knowledge in natural investigation of human function, not in non-empirical direct apprehension. Gill’s developmental account of moral knowledge — in which the agent arrives at moral understanding through the process of ethical maturation — is explicitly empirical and inferential in structure. The C3 finding remains Divergent.
Net differential for Variant A: No finding changes category. C5 and C6 move modestly upward within Partial Convergence. C1, C2, C3 remain Divergent. The baseline audit governs.
Variant B — Cornell Realism / Synthetic Naturalism
Variant B holds moral properties to be identical to natural properties by synthetic a posteriori identification, not by conceptual analysis. This produces no shift on C1 or C2: the agent is still a natural organism embedded in the natural causal order. It produces no shift on C3: moral knowledge is still arrived at through investigation rather than direct apprehension, even if the investigation is philosophical rather than straightforwardly empirical. On C5 and C6, Variant B is comparably placed to Variant A — robustly realist but grounding objectivity in natural rather than freestanding moral facts.
Net differential for Variant B: No finding changes category. The baseline audit governs throughout.
Variant C — Evolutionary or Social-Functional Naturalism
Variant C grounds moral facts in evolutionary fitness, adaptive advantage, or the functional requirements of stable social life. This produces downward pressure on C6 (Moral Realism): if moral facts are determined by evolutionary history or local social function, their objectivity is contingent in a way that the corpus’s moral realism cannot accommodate. The finding on C6 moves from Partial Convergence toward Divergent for Variant C. Variant C also produces downward pressure on C5 (Correspondence Theory): if moral claims correspond to evolutionarily or socially determined facts rather than to a mind-independent moral reality, the correspondence relation is of a different and weaker kind than the corpus requires.
On C1, C2, and C3, Variant C does not shift the findings; in fact, its more thoroughgoing naturalism deepens the divergence on C1 and C3.
Net differential for Variant C: C6 moves from Partial Convergence toward Divergent. C5 weakens within Partial Convergence. The baseline audit’s Divergent findings on C1, C2, and C3 are reinforced rather than softened. Variant C represents the most philosophically divergent form of ethical naturalism from the corpus’s standpoint.
Significance of the Variant Differential: The differential shows that the ideology’s internal variation is philosophically significant primarily on C5 and C6, where Variant A represents the most favorable form for an agent who holds the six commitments. However, no variant shifts any of the three Divergent findings (C1, C2, C3). The core divergences are invariant across all forms of ethical naturalism. An agent who adopts any form of the position must accept the C1, C2, and C3 presuppositions as load-bearing elements of the ideology, regardless of which variant he favors.
Self-Audit — Step 3:
- Have I examined variant-specific presuppositions rather than surface differences? Yes. The differentials identified are grounded in load-bearing presuppositions specific to each variant.
- Have I identified differentials where none exist in order to soften the baseline finding? No. The baseline Divergent findings on C1, C2, and C3 are confirmed as invariant.
- Have I stated clearly which variant-specific presuppositions are load-bearing? Yes.
Self-Audit Complete. Proceeding to Step 4.
Step 4 — Dissolution Finding
Governing question: Does ethical naturalism’s architecture require the agent to dissolve himself into an external system?
C1: Divergent.
C2: Divergent.
Both Commitment 1 and Commitment 2 are Divergent. The dissolution rule applies without qualification.
Dissolution Finding: Full Dissolution.
Ethical naturalism structurally requires the agent to understand himself as a natural organism embedded in and constituted by the natural order, whose inner life is continuous with natural processes and whose assents are events within a causally ordered natural system. No residue of a categorically distinct rational faculty standing prior to and independent of those conditions remains within the ideology’s architecture. The self-governing rational faculty the corpus identifies as the agent’s true identity — the prohairesis that is categorical prior to all externals, including the body — has no place in a framework in which the agent is a natural kind member assessed by natural standards.
An agent who adopts ethical naturalism as his governing self-description must understand himself as constituted by forces external to what the corpus calls his prohairesis, and his assents as events within the causal order rather than genuine originations. This is the structure the corpus identifies as the root of pathos: the implicit placement of the agent’s identity and wellbeing in conditions external to his genuine self-governing capacity.
Variant differential applied to dissolution: No variant shifts the dissolution finding. All three variants of ethical naturalism hold P3 (the agent as natural organism) and the compatibilist account of agency that follows from it. Variant A, the most philosophically developed and most hospitable to moral seriousness, does not posit a categorically distinct rational substance. The Full Dissolution finding is invariant across all variants.
This is a philosophical finding, not a political verdict. Ethical naturalism is not thereby condemned as institutionally unjust, strategically misguided, or historically failed. The finding is narrower: it identifies what the ideology requires of an agent who adopts it as a governing self-description, specifically what it requires him to accept about the nature of his own rational faculty and its relationship to the natural world.
Self-Audit — Step 4:
- Does the dissolution finding follow mechanically from the commitment-level findings? Yes. Both C1 and C2 are Divergent. Full Dissolution follows without adjustment.
- Is the dissolution finding stated as a philosophical finding, not a political verdict? Yes.
- Has the variant differential been applied correctly to the dissolution finding? Yes. No variant shifts it.

Step 5 — Summary Finding
Part A — Commitment Pattern
| Commitment 1 — Substance Dualism | Divergent |
| Commitment 2 — Libertarian Free Will | Divergent |
| Commitment 3 — Ethical Intuitionism | Divergent |
| Commitment 4 — Foundationalism | Partial Convergence |
| Commitment 5 — Correspondence Theory of Truth | Partial Convergence |
| Commitment 6 — Moral Realism | Partial Convergence |
Pattern summary: Three Divergent (C1, C2, C3); three Partial Convergence (C4, C5, C6). No Convergent findings. No Orthogonal findings.
Deepest point of divergence: C1, C2, and C3 together constitute a structural cluster of divergences that are not independent. They are entangled: the denial of substance dualism (C1) forces the compatibilist account of agency (C2), which in turn closes off the non-empirical rational apprehension required by ethical intuitionism (C3). A faculty embedded in the natural causal order cannot be the genuine originator of its own assents (C2) and cannot have the categorically distinct mode of access to moral truth that intuitionism requires (C3). The three Divergent findings are not three separate problems; they are three expressions of the same underlying commitment to naturalizing the moral subject and moral knowledge.
Strongest point of convergence: C5 and C6 in Variant A. Aristotelian eudaimonist naturalism holds moral claims to be genuinely objectively true, determined by mind-independent facts about human nature and flourishing. This is a genuine point of convergence with the corpus’s realism and correspondence theory, even though the grounding of that objectivity differs fundamentally. An agent who holds Variant A is not a moral relativist or a constructivist; he holds a position in which moral claims have real truth conditions. This is worth acknowledging as a philosophical strength, even as the audit identifies the three structural divergences that prevent compatibility.
Part B — Dissolution Finding
Full Dissolution. Invariant across all variants.
Ethical naturalism’s architecture requires the agent to understand himself as a natural organism whose inner life is continuous with the natural causal order, whose assents are events within that order rather than genuine originations, and whose moral knowledge is derived from investigation of nature rather than directly apprehended by a categorically distinct rational faculty. No version of the position preserves the ontological boundary that the corpus requires for the dichotomy of control to be real.
Part C — Agent-Level Implication
An agent who adopts ethical naturalism as his governing philosophical self-description faces the following set of implicit commitments.
On self-description: he must understand himself as a natural organism, a member of a natural kind, whose identity is constituted by his natural capacities and their exercise in relation to others and to his natural environment. He does not have a categorically distinct rational faculty standing prior to his body and social conditions. His “inner life” is the inner life of a complex natural being, not the inner life of a self-governing soul that is genuinely external to the material world. He has, at the level of self-description, accepted what the corpus identifies as the foundational false dogma: the identification of himself with something that belongs to the external order.
On agency: he must understand his assents and choices as events within the natural causal order, flowing through his rational character but determined by the prior conditions that produced that character. His choices are genuinely his in the compatibilist sense — they flow from who he is — but they are not genuinely his in the libertarian sense the corpus requires. The guarantee of eudaimonia that the corpus places in correct assent depends on assent being a genuine origination, not a determined output. An agent who has accepted the naturalist account of agency cannot coherently claim that guarantee, because the causal story his own framework tells about his assents is one in which the assent’s character was settled before the moment of apparent choice.
On moral knowledge: he must understand moral knowledge as arrived at through a process of investigation and development, not through direct non-empirical apprehension of self-evident truths. The claim that externals are not genuinely good or evil — the foundational corrective proposition of Sterling’s Stoicism — is not available to him as a directly apprehensible moral fact. It must be derived, developed, earned through the process of ethical maturation. This means the corrective criterion by which false dogmata are identified and refused is not immediately available to his rational faculty; it is a conclusion he is working toward, which means it cannot function as the instrument of correction at the points in his development where he most needs it.
The most practically significant implication is what follows from the Full Dissolution finding for the practice of Stoicism. The practical mechanisms of Stoic self-examination — prosochē, the discipline of assent, the evening review examined in “The Relationship Between Stoicism and Personal Examination” — are practices addressed to the prohairesis as a categorically distinct self-governing faculty. They are practices of guarding and correcting assent understood as genuine origination. An agent who has accepted the naturalist account of the self is practicing techniques whose rationale requires a kind of self that his philosophical self-description has denied. He is, at the level of philosophical presupposition, using an instrument designed for a different kind of agent than the one he takes himself to be.
This does not mean that an agent who holds ethical naturalism cannot benefit from Stoic practice. The practical benefits of prosochē and the discipline of assent may accrue to him regardless of his philosophical self-description. But it does mean that his philosophical account of those practices is incoherent: he cannot provide, within his own framework, a consistent explanation of why those practices are addressed to the right thing, why the faculty they target is what they take it to be, or why the guarantee they are supposed to secure — that correct assent guarantees eudaimonia — holds for an agent whose assents are events in a causally determined natural order. The practices are borrowed from a framework whose philosophical foundations the naturalist has declined to accept.
The relationship between Gill’s naturalist Stoicism and the Sterling framework, including the precise points at which the naturalist account fails to sustain the practical requirements of Stoic ethics, is examined in detail in “Virtue, Assent, and the Locus of the Good: Sterling’s Stoicism and the Limits of Gill’s Naturalism.”
Corpus Boundary Declaration: The CIA issues no findings on whether ethical naturalism is a correct account of moral epistemology, whether the Aristotelian eudaimonist version offers the best available secular account of virtue, whether it provides a superior foundation for environmental ethics or political philosophy, or whether any of its substantive moral claims are correct. Those are questions outside the corpus’s domain and outside the CIA’s reach. The findings are restricted to the philosophical presuppositions of the ideology and their entailments for an agent who adopts it as a governing self-description.
Self-Audit — Step 5:
- Does the summary follow from the preceding steps, or has new material been introduced? The summary follows from Steps 1–4. No new analytical finding appears at the synthesis stage.
- Has the agent-level implication been stated without converting it into a political verdict? Yes.
- Has the corpus boundary declaration been issued accurately? Yes.
- Is the summary self-contained? Yes.
