Greek, 341–270 BC.

He taught that pleasure and pain are measures of what is good and evil; death is the end of both body and soul and should therefore not be feared; the gods neither reward nor punish humans; the universe is infinite and eternal; and events in the world are ultimately based on the motions and interactions of atoms moving in empty space.(...)"
