Worms' turn

Between them, Darwin and Freud killed God and defined our modern world. But
they left us with a problem. In a world without God, where nature is all, how do
we distinguish the natural from the unnatural? Adam Phillips, in Darwin’s Worms,
goes on a journey into the great men’s lives in search of some answers.
