Psychology is not applied biology, nor is biology applied chemistry. Many people think reality is prosaic. We don't explain things away in science. We get closer to the mystery. What does happen is that its opponents gradually die out and that the growing generation is familiarized with the idea from the beginning.

It's not this foreign thing, done by an arcane priesthood. It's one of the glories of human intellectual tradition. The pop artist Andy Warhol once approached me at a party and told me that he collected scientific journals, but he couldn't understand them. And anyhow, I have this place called the Factory where my helpers do it. That theory is worthless.
