People like Heraclitus

Heraclitus of Ephesus (; Greek: Ἡράκλειτος Herákleitos, "Glory of Hera"; fl. c. 500 BCE) was an ancient Greek pre-Socratic philosopher from the city of Ephesus, which was then part of the Persian Empire.

Little is known of Heraclitus's life. He wrote a single work, only fragments of which have survived. Most of the ancient stories about him are later fabrications based on interpretations of the preserved fragments. His paradoxical philosophy and appreciation for wordplay and cryptic utterances has earned him the epithet "the obscure" since antiquity. He was considered a misanthrope who was subject to melancholia. Consequently, he became known as "the weeping philosopher" in contrast to the ancient philosopher Democritus, who was known as "the laughing philosopher".
