C2 — Libertarian Free Will (Origination of Assent)l

Within Sterling’s Stoicism, libertarian free will is the condition that makes agency real rather than apparent. It is the claim that the agent (See C2) is the genuine source of action, such that acts of assent are not determined outputs of prior causes but instances of true origination. This is not merely a thesis about freedom in a weak sense. It is a claim about authorship: the agent does not merely undergo decisions but produces them.

The core of libertarian freedom is agency understood as self-determination. When the agent encounters an impression, there is a real decision point—what Sterling calls the Pause—at which deliberation occurs. At that point, multiple alternative possibilities are genuinely open. The agent could have done otherwise. This is not epistemic uncertainty but metaphysical openness. The resulting act is a non-determined act, an instance of internal causation (strong sense), where the cause terminates in the agent rather than in prior external or physical conditions.

This structure grounds choice as a real event. A choice is not simply the unfolding of prior states but an action initiation attributable to the agent. This is why libertarian freedom is inseparable from control. To say that assent is “in our control” is to say that it originates from us, not merely that it passes through us. Without origination, control collapses into passive participation in a causal chain.

This has direct implications for responsibility and accountability. If the agent is the true origin of assent, then the agent is properly subject to moral responsibility. Praise and blame are not projections but accurate evaluations of what the agent has authored. If, by contrast, every act were determined by prior causes, then responsibility would be misplaced. The agent would be a locus of events, not their originator.

This commitment is essential to Foundation One: that only internal things are in our control. Libertarian free will ensures that internal acts are not merely internal in location but internal in authorship. Combined with substance dualism, it establishes that the rational faculty is both distinct from externals and actively originating its responses. Without libertarian freedom, the dichotomy of control reduces to a distinction between types of causes, not a distinction between what is truly up to us and what is not.

It is equally necessary for Foundation Two: that unhappiness is caused by false value judgments. The framework claims that agents are responsible for assenting to false propositions about externals. That claim presupposes that the agent could have withheld assent. If assent were causally inevitable, then false judgment would not be an error attributable to the agent but an unavoidable outcome. The entire structure of correction—identifying, rejecting, and replacing false judgments—requires genuine freedom at the point of assent.

Most critically, libertarian free will is indispensable for Foundation Three: that right assent guarantees eudaimonia. The guarantee only holds if the agent can actually produce right assent. If every assent were fixed by prior causes, then the guarantee would collapse into fatalism: those who achieve eudaimonia were always determined to do so, and those who fail never had a real alternative. Libertarian freedom preserves the guarantee as a meaningful claim: the agent can, at each decision point, align with reality or fail to do so.

Thus libertarian free will integrates with the other commitments. It works with substance dualism to establish a genuine agent; with moral realism and correspondence to give assent something real to align with; with intuitionism to make correct judgment accessible; and with foundationalism to make correction systematic. It is the action-theoretic core of the system.

This position explicitly discriminates against three alternatives.

Determinism denies that alternative possibilities are real and reduces action to causal inevitability. Under determinism, the agent never truly originates anything.

Compatibilism redefines freedom as action flowing from internal states without external constraint. But this preserves neither origination nor genuine alternatives; it replaces authorship with internal causation in a weak sense.

Causal inevitability more broadly denies that anything could occur otherwise than it does, eliminating the possibility of real choice at the point of action.

Against all three, libertarian free will asserts that the agent is a true source of action. The rational faculty does not merely process impressions—it determines its response to them.

In Sterling’s Stoicism, therefore, libertarian free will is not optional. It is what makes assent a genuine act, control a real property, responsibility a justified attribution, and eudaimonia a reachable state. It secures the claim that flourishing depends on what the agent does because what the agent does is truly up to the agent.
