Anaxagoras

Pre-Socratic

Born c. 500 BCE

Died c. 428 BCE

Mind orders the cosmos. He brought philosophy to Athens and was exiled for saying the sun is a hot rock, not a god.

Anaxagoras came from Ionia to Athens and became the first philosopher to live and teach there. He proposed that an infinite number of seeds make up all things, and that Nous (Mind) set the cosmos in motion. He was a friend of Pericles. The Athenians put him on trial for impiety because he taught that the sun is a mass of burning metal, not a deity. He was convicted and exiled. He spent his last years in Lampsacus.
