Heraclitus
Everything flows — the Obscure One
The dark philosopher of Ephesus. His surviving fragments — oracular, paradoxical, magnificent — declare that everything is in flux, that opposites are one, and that fire is the logos of the cosmos. 'You cannot step into the same river twice.' Hegel, Nietzsche, and Heidegger all claimed him as ancestor.
