The Philosophical Grounding Audit (PGA) — Version 1.0
Instrument architecture: Dave Kelly, 2026. Theoretical framework: Grant C. Sterling. Prose rendering: Claude.
Instrument Position
The Philosophical Grounding Audit sits in the corpus instrument hierarchy as follows. The Sterling Logic Engine audits an individual agent’s assents against the 80 propositions. The Classical Ideological Audit audits an ideology’s presuppositions against the six commitments. The Classical Presupposition Audit audits a named public figure’s argumentative presuppositions against the six commitments. The Sterling Corpus Evaluator evaluates any idea against the full corpus. The Sterling Decision Framework determines action. The Philosophical Grounding Audit tests whether the six commitments of Sterling’s Stoicism are load-bearing for any specified practical ethics — whether the commitments are the correct philosophical ground for that practical ethics, not merely consistent with it.
Every existing instrument uses the six commitments as the measuring stick. The PGA reverses the direction. The practical ethics under examination is the fixed text. The six commitments are what is being tested for their load-bearing relationship to that text. This is a different question requiring a different procedure, and no existing instrument performs it.
Part One — The Evidential Question and the Load-Bearing Standard
Section 1: Three Possible Relationships
A philosophical framework can stand in three distinct relationships to a practical ethics. The PGA recognizes all three and tests only for the third.
Consistency. The framework is compatible with the practical ethics. Its commitments do not contradict the practical ethics’ claims. This is the weakest possible relationship. A position is consistent with many things it does not require. Consistency is not evidence of grounding.
Anticipation. The framework historically precedes the practical ethics and partially generates it. The practical ethics draws from the framework’s tradition and carries some of its commitments forward. This is a stronger relationship than consistency but still insufficient. A framework can anticipate a practical ethics at some commitments and diverge from it at others. Anticipation commitment by commitment is not the same as load-bearing necessity.
Load-bearing necessity. The practical ethics structurally requires the framework. Remove any commitment and a specific element of the practical ethics fails — not weakens, fails. The argument cannot proceed as stated without that commitment doing its structural work. This is the relationship the PGA tests for. A positive finding at this level establishes that the framework is the correct philosophical ground for the practical ethics, not merely an ancestral tradition or a compatible position.
The distinction between consistency and load-bearing necessity is the instrument’s central methodological claim. It must be maintained throughout every run. Any finding that rests on consistency rather than necessity is a named failure mode.
Section 2: The Strict Evidentiary Standard
For each of the six commitments, the demonstration must meet four requirements in sequence.
First — Passage identification. A specific argument or passage in the practical ethics under examination must be identified. General appeal to the overall character of the practical ethics is insufficient. The passage must be the locus where the commitment does its structural work.
Second — Function specification. What the commitment makes possible in that specific argument must be stated. This is not a description of what the commitment is. It is a statement of what would be unavailable to the argument without the commitment — what structural work the commitment performs that no other resource in the practical ethics can perform.
Third — The load-bearing argument. The structural dependency must be constructed explicitly. The argument must show why the practical ethics’ argument requires this commitment at this point, not merely why the commitment is compatible with it or historically associated with it.
Fourth — The named failure. The failure that results from removing the commitment must be stated precisely. This is the evidentiary crux. If the failure cannot be named — if removing the commitment only weakens the argument or creates a gap that could be filled by other resources — the finding is partial rather than fully load-bearing.
All four requirements must be met for a fully load-bearing verdict on any single commitment.
Section 3: The Fairness Constraint
The demonstration must work from the actual text of the practical ethics under examination. Attribution of commitments to the practical ethics must be grounded in specific passages, not in what characteristically accompanies those commitments in philosophical discourse, and not in what the practical ethics would need to hold in order to be more fully aligned with the corpus.
The governing question at every point is: does this argument, as this author states it, structurally require this commitment? Not: would this argument be stronger with this commitment? Not: is this commitment compatible with what this author says? The question is structural requirement, and the evidence must come from the text.
Failure to apply the fairness constraint is named as Failure Mode 3 — Presupposition Substitution.
Section 4: Scope of the Instrument
The PGA operates on two categories of practical ethics.
External practical ethics. Practical ethical systems that predate or exist independently of the corpus — primarily Epictetus’s ethical psychology as expressed in the Enchiridion and the Discourses. The PGA tests whether the six commitments are load-bearing for arguments Epictetus actually makes in those texts. This is the instrument’s primary historical application and the one for which it was first developed.
Corpus practical ethics. Practical documents produced within this project — the Five-Step Method, the role manuals, the Sterling Decision Framework, the Integrated Practical Model, the Governing Narrative Poetics framework, the Correct Stoic Attitude manual, and any future corpus output that carries a claim to rest on Sterling’s theoretical foundations. The PGA tests whether that claim holds at the passage level — whether the six commitments are genuinely operative in each document’s structure, or whether the attribution line is carried without the load-bearing relationship having been demonstrated rather than assumed.
The internal audit function is the PGA’s most significant ongoing application. The corpus has grown substantially. Not every document has been subjected to commitment-by-commitment load-bearing scrutiny. The PGA provides the procedure for verifying that the practical architecture is genuinely built on the theoretical foundations rather than merely labeled as such.
Part Two — The Commitment-by-Commitment Demonstration
Section 5: Structure of Each Commitment Test
Each commitment is tested using the following four-part structure, applied to the practical ethics specified at the opening of the run.
The passage. The specific argument or passage in the practical ethics where this commitment does its structural work.
What the commitment makes possible. The structural function the commitment performs in that argument — what would be unavailable without it.
The load-bearing argument. The explicit construction of the structural dependency, showing why the argument requires this commitment at this point.
Without this commitment. The named failure that results from removing the commitment. Stated in precise terms: which specific element of the argument fails, and how.
Section 6: Verdict Architecture
Four verdicts are available per commitment.
Fully load-bearing. All four requirements of the strict evidentiary standard are met. The commitment is structurally necessary for a specific argument in the practical ethics. Without it, a named element of that argument fails as stated.
Partially load-bearing. The commitment does real structural work but the failure without it is degradation rather than collapse. The argument weakens or loses precision but does not fail entirely. The specific element that degrades must be named.
Not load-bearing. The commitment plays no structural role in the practical ethics under examination. It may be consistent with the practical ethics or historically associated with it, but the practical ethics’ arguments do not require it. No failure results from its absence.
Structural conflict. The practical ethics requires something incompatible with the commitment. This is the strongest negative finding and is distinct from “not load-bearing.” A structural conflict means the practical ethics cannot accommodate the commitment without revising one of its own arguments. The specific incompatibility must be named.
Section 7: Summary Verdict
Following the six commitment tests, a summary verdict is issued covering three questions.
First: how many of the six commitments are fully load-bearing for the practical ethics under examination? The per-commitment verdicts are collected and the pattern is identified.
Second: are any structural conflicts present? A structural conflict is a significant finding that must be addressed in the summary — it means the practical ethics and the SCPC are incompatible at that commitment, not merely that the commitment is absent.
Third: what is the overall grounding verdict? If all six commitments are fully load-bearing, the finding is: the SCPC is the correct philosophical ground for this practical ethics. If fewer than six are fully load-bearing, the summary must specify whether the gaps are absences (not load-bearing) or conflicts (structural incompatibility), and what the implication is for the grounding claim.
Section 8: Named Failure Modes
Failure Mode 1 — Consistency Substitution. Treating compatibility between a commitment and a practical ethics position as evidence of load-bearing necessity. This is the instrument’s primary failure risk because consistency is easier to establish and easier to mistake for the stronger finding. A finding that rests on the absence of contradiction rather than on structural dependency is a Consistency Substitution failure.
Failure Mode 2 — Anticipation Substitution. Treating historical precedence or partial generation as evidence of load-bearing necessity. A practical ethics may draw from a philosophical tradition that carries a commitment without that commitment being structurally required by the practical ethics’ own arguments. The historical relationship is not the grounding relationship.
Failure Mode 3 — Presupposition Substitution. Attributing to the practical ethics commitments it does not actually require, drawn from the framework under examination rather than from the text itself. The governing question is always: does this argument, as this author states it, structurally require this commitment? Importing commitments the author would need in order to be more aligned with the corpus is a Presupposition Substitution failure.
Failure Mode 4 — Scope Inflation. Claiming a commitment is load-bearing for the whole practical ethics when the passage evidence supports only that it is load-bearing for one specific argument or element. The verdict must match the scope of the evidence. A fully load-bearing verdict for one passage does not establish a fully load-bearing verdict for the practical ethics as a whole unless the passage is genuinely foundational to the whole.
Failure Mode 5 — Text Bypass. Running the demonstration from general knowledge or training-data pattern-completion rather than from the actual text of the practical ethics. The fairness constraint requires the text. Without it the load-bearing argument cannot be distinguished from what characteristically accompanies a commitment in philosophical discourse. Text Bypass is the failure mode that ruled out a general version of this instrument applicable to external philosophical frameworks without corpus grounding.
Section 9: Mandatory Self-Audit
The self-audit is conducted at each commitment transition and at the summary verdict.
- CONSISTENCY SUBSTITUTION — Is the load-bearing argument grounded in structural dependency or in the absence of contradiction?
- ANTICIPATION SUBSTITUTION — Is the finding grounded in what the text structurally requires or in what the text’s tradition historically carried?
- PRESUPPOSITION SUBSTITUTION — Are all attributed commitments drawn from what the text’s own arguments require, not from what the corpus would need them to hold?
- SCOPE INFLATION — Does the verdict match the scope of the passage evidence?
- TEXT BYPASS — Is the argument grounded in the actual text of the practical ethics under examination?
Any failure detected at audit halts the run. The failure is stated, its grounds specified, the correct procedure identified, and the run resumes only after the corrected analysis is produced.
Section 10: Completed Runs
