The Sterling Approach Is Structurally Internalist by Necessity

The Sterling Approach Is Structurally Internalist by Necessity

ChatGPT:

That is correct, and it sharpens the contrast even further.

The Sterling/Kelly system is not merely “more internalist” by emphasis. It is structurally internalist by necessity, because it is built on two tightly integrated layers:

• the Six Philosophical Commitments
• the internalist value structure (only assent is good/evil; externals are value-neutral)

These are not separable. Each commitment underwrites a specific element of internalism.

1. The Six Commitments as the foundation of internalism

Each commitment closes off a route by which value could leak into the external world.

Substance Dualism
Separates the rational faculty from the body and all externals. This makes it possible to locate the self—and therefore the good—entirely within the rational faculty.

Metaphysical Libertarianism
Secures genuine control at the point of assent. If assent were causally determined, internalism would collapse. The entire system depends on the agent being able to withhold or grant assent freely.

Ethical Intuitionism
Provides direct access to moral truth without reliance on external outcomes or empirical success. This prevents action in the world from becoming the criterion of correctness.

Foundationalism
Stops regress at basic moral truths (e.g., “virtue is the only good”). These are not derived from social practice, political arrangements, or consequences.

Correspondence Theory of Truth
Turns impressions into truth-apt propositions. Assent is correct when it matches reality, not when it produces desirable external results.

Moral Realism
Ensures that the claim “externals are not good or evil” is an objective fact, not a therapeutic stance or practical heuristic.

Taken together, these commitments force a single conclusion:

The only place where good and evil can exist is in the rational faculty’s assent to impressions.

2. The internalist value structure

From that foundation follows the core value thesis:

• Only virtue (correct assent) is good
• Only vice (false assent) is evil
• All externals are indifferent (though some are preferred)

This is not an optional interpretation. It is the direct output of the six commitments.

And once this is accepted, several consequences follow with necessity:

• No external state of affairs can be good or bad in itself
• No political outcome can carry intrinsic moral value
• No social condition can damage or improve the good
• No action in the world can be the locus of virtue

Action becomes:

• the execution of a role
• guided by correct assent
• directed toward preferred indifferents
• always under reservation

But never morally constitutive.

3. Why this excludes Gill’s extension into action

Gill’s position requires that virtue be meaningfully expressed in:

• social relations
• political engagement
• responses to injustice
• lived ethical development

That requires that the external domain carry some degree of moral significance beyond mere indifference.

But the Sterling framework blocks that at every level:

• Dualism prevents identifying the good with embodied or social life
• Libertarianism locates responsibility at assent, not outcome
• Intuitionism bypasses empirical or social validation
• Foundationalism prevents deriving value from practice
• Correspondence theory evaluates beliefs, not actions
• Moral realism fixes the truth that externals are not good or evil

So the system cannot consistently say:
“Justice is realized in political action”

It can only say:
“Justice is correct assent, which may issue in certain political actions”

That is a hard boundary, not a stylistic preference.

4. The resulting architecture

The Sterling/Kelly model produces a highly compressed ethical structure:

• Moral locus: assent only
• Causal chain: impression → assent → impulse → action
• Evaluation point: assent
• Action status: external, non-value-bearing
• Externals: indifferent
• Eudaimonia: guaranteed by correct assent alone

Gill’s model distributes ethical weight across a broader field:

• Moral locus: character expressed in life
• Causal chain: development → understanding → action
• Evaluation point: lived conduct and relational practice
• Action status: morally expressive
• Externals: not “goods” in a crude sense, but morally significant
• Eudaimonia: tied to virtuous living in a social world

5. Final clarification

So the difference is not merely that:

• Sterling is stricter
• Gill is more practical

It is that Sterling’s system is logically closed around internalism, because the Six Commitments make any externalization of value incoherent.

Once those commitments are in place, the following becomes unavoidable:

Virtue cannot extend into action as a value-bearing domain.
It can only govern action from within.

That is why the Sterling approach is not just one version of Stoicism among others. It is a reconstruction in which internalism is not an emphasis, but a consequence of its philosophical foundations.
