The setting

A terse phrase transmitted in the later doxographical tradition alongside B64, glossing the directive fire: 'the fire is intelligent.' It supplies the mind that B64's steering thunderbolt implies — the fire that governs is not blind.

A note on this passage

Three words answer the question B64 leaves open: what steers all things by the thunderbolt? A fire that thinks. <em>Phronimon</em> is not abstract cleverness but practical wisdom — the good judgment that governs conduct — so the claim is that the cosmic fire steers well, with something like know-how, not by accident. It draws the fragments' physics and their theology together: the fire that is the world's first principle (B30, B90) is also the 'one wise thing' that governs everything (B41).

This is the seed the Stoics grew into an entire system — the <em>pyr technikon</em>, the 'craftsman-like fire' or <em>logos</em> that is providence itself. Whether Heraclitus meant a mind as separate as the Stoics' god is doubtful; more likely the intelligence is immanent, the very lawfulness by which fire kindles and quenches in measure. The fire does not consult a plan outside itself. Its intelligence is the order it already is.
