Quote by Carl Sagan

“Plato and Aristotle were comfortable in a slave society. They offered justification for oppression. They served tyrants. They taught the alienation of the body from the mind (a natural enough ideal in a slave society); they separated matter from thought; they divorced the Earth from the heavens - divisions that were to dominate Western thinking for more than twenty centuries. Plato, who believed that 'all things are full of gods,' actually used the metaphor of slavery to connect his politics with his cosmology. He is said to have urged the burning of all of the books of Democritus (he had a similar recommendation for the books of Homer), perhaps because Democritus did not acknowledge immortal souls or immortal gods or Pythagorean mysticism, or because he believed in an infinite number of worlds. Of the seventy-three books Democritus is said to have written, covering all of human knowledge, not a single work survives. All we know is from fragments, chiefly on ethics, and secondhand accounts. The same is true of almost all the other ancient Ionian scientists.”
