Fate & Free Will

εἱμαρμένη / προαίρεσις

If everything is causally fated, can our choices still be our own? — the ancient knot the Stoics tried to untie with an early form of compatibilism.

Also: heimarmene · proairesis · determinism · compatibilism · free will · fate · clinamen · Stoic fate

The problem of fate (`heimarmenē`) and human agency was systematically developed by the **Stoics** — chiefly Chrysippus (3rd c. BCE) — who held a strict causal determinism but defended a compatibilist account of responsibility. Chrysippus's famous *cylinder analogy* illustrated the position: an external cause (a shove) gets the cylinder rolling, but how it rolls is determined by its own internal shape; likewise, external impressions impinge on us, but our assent or refusal expresses our own character. This defeated the "Lazy Argument" (if everything is fated, why try?) by distinguishing fated *outcomes* from the *co-fated* actions that bring them about (preserved in Cicero, *De Fato* 41–43).

Plato's *Myth of Er* (*Republic* X 617d–620e) is the famous Greek image of the problem — "virtue is without a master; the responsibility is the chooser's, god is blameless" — but Plato did not develop a technical theory. The Epicureans introduced the `clinamen` or *swerve* (parenklisis, Lucretius II.216–293) — a minute uncaused deviation of atoms — to preserve genuine freedom against atomic determinism. Carneades the Academic Skeptic constructed an early argument that responsibility does not require indeterminism. Alexander of Aphrodisias's *De Fato* (2nd–3rd c. CE) gave the major ancient libertarian refutation of Stoic compatibilism. The Greek term `proairesis` ("choice") is itself Aristotelian (NE III.2–3) but was adopted by Epictetus as the central concept of late-Stoic practical philosophy (*Discourses* I.1).
