Anaxagoras, the friend and master of Pericles, Euripides, and Socrates, was accused by the superstitious Athenians of atheism and impiety to the gods. He was condemned to death and barely escaped this fate through the influence of Pericles; which resulted in the accusation of atheism against Pericles. Euripides was accused of heresy, and Aeschylus was condemned to be stoned to death for blasphemy and was saved from this fate by his brother Aminias. The philosophy of Parmenides was distinctly pantheistic, and Pythagoras, who attempted to purify the religion of the Greeks and free it from its absurdities and superstitions, was exiled for his scepticism. Democritus, a materialist and atheist of 2500 years ago, formulated a mechanical view of phenomena in accordance with which everything that happens is due to physical impacts. "Such a materialism was a great liberation from superstition; and had it survived in its integrity, the path of European wisdom would have been vastly different from what it was. What the path would have been, we are beginning to see to-day, for since the nineteenth century we have been treading it more or less consistently but by no means so gallantly and courageously as Democritus." (_G. Boas: "The Adventures of Human Thought."_) Democritus and the Epicureans strove to deliver men from their two chief apprehensions: the fear of the gods, and the fear of death; and in so doing rejected the religious beliefs and substituted a rational and scientific conception of the universe. It was Xenophanes, the Voltaire of Greece, who brought to the attention of his countrymen the discovery that man created the gods in his own image. He attacked the conceptions of the Greek deities with these words, "Mortals deem that the gods are begotten as they are, and have clothes like theirs, and voice and form ... Yes, and if oxen and horses or lions had hands, and could paint with their hands, and produce works of art as men do, horses would paint the forms of the gods like horses, and oxen like oxen, and make their bodies in the image of their several kinds.... The Ethiopians make their gods black and snub-nosed; the Thracians say theirs have blue eyes and red hair." Considering Greek philosophy in its entirety, we see that it was naturalistic rather than supernaturalistic, and rationalistic rather than mystical. These gifted men saw no clear indication for the existence of a supreme being; very few of them speak of the deity in the role of Providence and fewer still believed in personal immortality.
