"These ideas are present in all sorts of unrelated cultures -- the Easter Islands, Celtic mythology, Plato's Symposium with its notion that we are all originally hermaphrodite. We became too arrogant and so the gods split us down the middle, forcing us to spend our lives chasing our other half. If we start being arrogant all over again, God will come down and split each half in half, and it will take four people to assemble a fifth, making our lives peculiarly, desperately difficult."
