“I said at the beginning of this ramble that life is meaningless. It is not a flippant assertion. I think it’s absurd, the idea of seeking ‘meaning’ in the set of circumstances that happens to exist after 13.8 billion years’ worth of unguided events. Leave it to humans to think the universe has a purpose for them. However, I am no nihilist. I am not even a cynic. I am, actually, rather romantic. And here’s my idea of romance: You will soon be dead.”

“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.”

“The Platonists and their Christian successors held the peculiar notion that Earth was tainted and somehow nasty, while the heavens were perfect and divine. The fundamental idea that the Earth is a planet, that we are citizens of the Universe, was rejected and forgotten. This idea was first argued by Aristarchus, born on Samos three centuries after Pythagoras. Aristarchus was one of the last of the Ionian scientists. By this time, the center of intellectual enlightenment had moved to the great Library of Alexandria. Aristarchus was the first person to hold that the Sun rather than the Earth is at the center of the planetary system that all the planets go around the Sun rather than the Earth. Typically, his writings on this matter are the lost. From the size of the Earth's shadow on the Moon during a lunar eclipse, he deduced that the Sun had to be much larger than the Earth, as well as very far away. He may then have reasoned that it is absurd for so large a body as the Sun to revolve around so small a body as the Earth. He put the Sun at the center, made the Earth rotate on its axis once a day or orbit the Sun once a year.
It is the same idea we associate with the name of Copernicus, whom Galileo described as the 'restorer and confirmer', not the inventor, of the heliocentric hypothesis. For most of the 1,800 years between Aristarchus and Copernicus nobody knew the correct disposition of the planets, even though it had been laid out perfectly clearly around 280 B.C.”
