Greek philosophers
Anaxagoras
Anaxagoras was a Greek pre-Socratic philosopher who was born in Klazomenai (Asia Minor) around 500 BC and died around 428 BC in Lampsacus. He belonged to the Ionian school of philosophy.
Among Anaxagoras' admirers was Pericles, and among his pupils was supposed to be Socrates. The crater Anaxagoras on the inverted side of the moon was also named after the philosopher.
Although Anaxagoras was Greek, he served in the Persian army. Upon his return to Athens (between 464 and 462 BC), he was arrested by his friend Pericles' opponents for opposing established religious principles. He was subsequently forced to leave Athens and returned to Lampsacus in Ionia, where he died.
In his view, everything exists from the beginning. In the beginning there were infinitely small, uncountable and at the same time different seeds. Into this world enters an omnipotent principle called mind/spirit. The individual parts form the whole, the cosmos. Aristotle subsequently built on these ideas.
