The Central Logical Spine
The system is not a collection of independent instruments. It is a single logical structure in which each layer makes the layer above it possible and is constrained by the layer below it. The spine runs as follows:
Six Commitments → Three Foundational Claims → 80 Propositions → Instruments → Outputs
Nothing at any level can override what is established at a lower level. An instrument finding that contradicts a proposition is a malfunction. A proposition that contradicts a commitment is impossible by definition. The spine is the system’s governing constraint, not a historical summary of how it was built. The spine was not planned — it was identified retrospectively as the logical order that the accumulated content required.
Layer One: The Six Commitments
The six commitments are Sterling’s original contribution and the philosophical floor of the entire system. They are not derived from Stoicism — they are what makes Sterling’s reconstruction of Stoicism philosophically defensible rather than merely asserted.
C1 — Substance Dualism makes the self/external boundary ontologically real. Without it, the control dichotomy is a practical heuristic rather than a metaphysical fact. The distinction between what is “up to us” and what is not collapses into a matter of degree rather than kind.
C2 — Libertarian Free Will makes assent a genuine act of origination. Without it, the discipline of assent is an illusion — the agent appears to choose but is determined. The entire framework becomes a description of mechanisms rather than a prescription for practice.
C3 — Moral Realism makes the verdict “this impression is false” objectively true rather than merely personally preferred. Without it, the value strip is a preference declaration, not a correction. The proposition that externals are neither good nor evil is a fact about reality, not a cultural option.
C4 — Correspondence Theory of Truth makes “false” mean “fails to match reality.” Without it, the correction of dogmata has no external standard to correct toward. A belief is false because it does not correspond to how things actually are, not because it is incoherent or unpopular.
C5 — Ethical Intuitionism gives the rational faculty direct epistemic access to moral truth. Without it, the agent has no way to know what virtue requires in a particular situation. Moral knowledge is not inferred from empirical observation — it is directly apprehended by the rational faculty attending to what is actually present.
C6 — Foundationalism organizes moral knowledge into a stable dependency structure with self-evident first principles at the base. Without it, the correction of a false belief has no firm ground to correct toward. Sterling’s smorgasbord warning — his insistence that you cannot pick and choose among the theorems — is foundationalism in operation.
The six commitments work simultaneously, not sequentially. Document 20 (The Six Commitments Integrated) shows all six active at once in the three foundational claims. The most philosophically demanding is Foundation Three — that right assent guarantees eudaimonia — which requires all six commitments to be simultaneously true for the guarantee to hold.
Layer Two: The Three Foundational Claims
The six commitments ground three foundational claims that are the operational heart of Sterling’s Stoicism:
Foundation One: The only things in our control are inner events — beliefs, desires, acts of will. (C1 and C2 are the philosophical warrant.)
Foundation Two: Virtue is the only genuine good; vice the only genuine evil; all externals are indifferent. (C3, C4, and C5 are the philosophical warrant.)
Foundation Three: Right assent guarantees eudaimonia. (All six commitments are simultaneously required.)
These three claims are the governing standard for everything above. Any instrument output, any blog post, any practical recommendation that contradicts one of these three is incorrect by definition — not by preference, not by majority opinion, but by the logical structure of the system.
Layer Three: The Propositional Architecture
The 80 Unified Propositions translate the three foundational claims into a closed axiom set that governs every subsequent instrument move. Sections I–VIII cover the core theoretical content: foundations, impressions and assent, value theory, causation of emotions, virtue and action, appropriate positive feelings, eudaimonia, and the Stoic path. These are the propositional expression of everything the six commitments and three foundational claims require.
Section IX — the Action Proposition Set (Props 59–80) — is Dave Kelly’s architectural addition, grounded in Sterling’s theoretical foundations. It governs the practical movement from correct value-judgment to rational action: role identification, goal selection, means selection, reservation, verification. Section IX presupposes Sections I–VIII and cannot substitute for them.
The propositions are the governing language of the instruments. Every instrument finding must cite the specific proposition that warrants it. An instrument that produces findings without propositional citation is operating from training data, not from the corpus. The source texts — Sterling’s Nine Excerpts and additional ISF writings — are the court of appeal when a proposition’s meaning is disputed.
Layer Four: The Instrument Architecture
The Logic Engine (SLE v4.0) is the self-examination instrument. It audits an individual agent’s own assents against the 80 Propositions. It asks: does this assent correspond to moral reality? It is the instrument most directly connected to the foundational claims. Every other instrument presupposes that the agent using it has either run the SLE or is operating from a position in which his own assents are already under examination.
The Decision Framework (SDF v3.3) is the procedural instrument. It takes the output of correct value-judgment and structures rational action from it. The six steps — Agent Check, Purview Check, Value Strip, Virtue Identification, Action Determination, Outcome Acceptance — are a procedural replication of what a person of correct judgment does naturally. The SDF is downstream of the SLE: correct action cannot be determined without first establishing correct value-judgment. The Factual Uncertainty Gate and the Named Failure Modes are architectural safeguards against the six most common instrument malfunctions.
The Integrated Practical Model is the operational layer beneath the SDF. Where the SDF specifies what propositions govern each step, the Integrated Practical Model specifies what the rational faculty must actually do at each moment. The corrective module (C1–C5) operationalizes Nine Excerpts Section 7 sub-steps (a) and (b). The constructive module (D1–D7) operationalizes sub-step (d). Its critical architectural limitation — that D2’s failure is undetectable by subsequent operations — is the reason Dave Kelly’s corrective layer is architecturally necessary, not merely advisable.
The Urge to Act is a supplementary practical document identifying the 7.b intervention point as the accessible entry point for the beginning prokōptōn. It is not an instrument — it produces no verdicts. It is an account of where training can practically begin and how the intervention point migrates upstream toward reception over time. It sits adjacent to the Integrated Practical Model and supplements the SDF’s Step 0 Agent Check by naming the urge as the first reliable diagnostic signal available to the early-stage practitioner.
The Corpus Evaluator (SCE v1.0) evaluates any idea against the full corpus. It is the most general-purpose instrument: where the SLE audits assents, the CIA audits ideologies, and the CPA audits public figures, the SCE can be directed at any idea, argument, or claim. Its hard limitation — that it cannot evaluate whether the corpus itself is correct — marks the outer boundary of what the system can honestly claim.
The Classical Ideological Audit (CIA v2.0) audits ideological frameworks against the six commitments. It operates at the ideology level, not the individual level. Its four verdict categories (Convergent, Partial Convergence, Divergent, Orthogonal) and dissolution criterion make it the system’s primary tool for political philosophy. The dissolution finding is a finding about what happens to those who adopt a framework, not a verdict about any individual’s inner life.
The Classical Presupposition Audit (CPA v1.0) audits named public figures’ argumentative records against the six commitments. It operates at the person level. The fifth verdict category — Inconsistent — distinguishes figures whose record requires contradictory presuppositions across domains. The Political Application Constraint governs all CPA work without exception.
The key relationship among the three audit instruments: the SLE looks inward at the agent’s own assents. The CIA looks outward at ideological frameworks as systems of ideas. The CPA looks outward at individual public figures as argumentative records. All three use the six commitments as test criteria but at different levels of analysis. None substitutes for another.
Layer Five: The Training Layer
This layer is the system’s largest gap and its practical base. The propositional warrant for training exists in Props 78–80. The Nine Excerpts supply the mechanism: repeated refusal of assent weakens false-value impressions over time; repeated correct assent strengthens correct ones. The Sage is simply someone who has controlled his assents so carefully for so long that false-value impressions no longer arrive.
What does not yet exist as a completed corpus document is a systematic training curriculum — a sequenced set of exercises grounded in the propositional architecture, organized by difficulty, and calibrated to the practitioner’s current intervention point. The Urge to Act is the first document that directly addresses where training begins. The Temperament-Based Stoic Psychology project — mapping all sixteen personality styles against the six commitments — is the other registered project direction for this layer.
Without training, the instruments can be executed nominally. The propositional verdicts can be produced. But the mental operations the commitments require may not be occurring. The training layer is what makes the instruments more than formal exercises.
Layer Six: The Role Architecture
The role architecture bridges the theoretical system and the world of action. Props 64–66 govern role identification; Props 68–71 govern role conflict resolution. Every role generates kathēkon — appropriate duties of action. Those duties are the content of rational action once the value strip has been correctly completed.
The eight economic role manuals apply the propositional architecture to specific role-contexts. They are downstream of the instruments: they presuppose correct value-judgment and apply the Section IX Action Proposition Set to role-specific situations. The MacIntyre framework — identifying the Manager, Therapist, and Aesthete as the character types produced by emotivist culture — is the diagnostic context for the role architecture. Sterling explicitly maps MacIntyre’s analysis onto the Stoic account of what happens when a culture loses virtue ethics as its organizing framework.
Layer Seven: The Political Philosophy Layer
The CIA is the instrument; the political philosophy layer is its application domain. CIA runs produce findings about ideologies and public figures. Those findings are Dave Kelly’s work, derived from Sterling’s theoretical foundations, and governed by the Political Application Constraint throughout.
The book project — systematic CIA application to nationalism, libertarianism, progressivism, conservatism, communitarianism, anarchism, and monarchism — is the major remaining gap in this layer. The CIA instrument is ready; the systematic application has not been executed.
The Governing Relationships — Summary
The six commitments govern everything. No instrument output, no blog post, no role manual can contradict what the six commitments require. They are not negotiable and not revisable from within the system.
The SLE and SDF are complementary, not redundant. The SLE audits value-judgment; the SDF structures action. The SLE must precede the SDF for the SDF to be operating correctly. An action determined without a prior value-judgment audit is structurally incomplete regardless of how well-reasoned it appears.
The Integrated Practical Model is the operational layer of the SDF, not a separate instrument. It describes what the faculty must actually do, not merely what propositions govern the output. Its undetectable failure at D2 is why the human corrective layer is architecturally necessary.
The audit instruments apply the six commitments externally; the SLE applies them to the agent himself. This is the fundamental distinction in the instrument hierarchy.
The training layer is the system’s practical base. Everything above it is available to the practitioner only insofar as his assents are actually under examination. Without training, the instruments can be executed nominally but the mental operations the commitments require may not be occurring. The training layer is what makes the instruments more than formal exercises.
The System Map (v2.6) is the authoritative governance document. When a question arises about what exists, what its status is, or how it relates to other corpus documents, the System Map is the court of first appeal.
