Heraclitus

Ancient Greek philosopher (fl. c. 500 BC)

Heraclitus (Ancient Greek: Ἡράκλειτος, romanized: Hērákleitos; fl. c. 500 BC) was a pre-Socratic Greek philosopher from the city of Ephesus, which was then part of the Persian Empire. He exerts a wide influence on Western philosophy, both ancient and modern, through the works of such authors as Plato, Aristotle, the Stoics, Georg Wilhelm Friedrich Hegel, Friedrich Nietzsche, and Martin Heidegger. Little is known of Heraclitus's life.
