Description: Heraclitus (Ancient Greek: Ἡράκλειτος Hērákleitos; fl. c. 500 BC) was an ancient Greek pre-Socratic philosopher from the city of Ephesus, which was then part of the Persian Empire. He exerts a wide influence on ancient and modern Western philosophy through the works of authors such as Plato, Aristotle, Hegel, and Heidegger. Little is known of Heraclitus's life. He wrote a single work, only fragments of which have survived, catalogued under philosopher number 22 in the Diels-Kranz numbering system. Even in ancient times, his paradoxical philosophy, appreciation for wordplay, and cryptic, oracular epigrams earned him the epithets "the dark" and "the obscure.".
