Religion is still parasitic in the interstices of our knowledge which have not yet been filled. Like bed-bugs in the cracks of walls and furniture, miracles lurk in the lacunae of science. The scientist plasters up these cracks in our knowledge; the more militant Rationalist swats the bugs in the open. Both have their proper sphere and they should realize that they are allies.

I think, however, that so long as our present economic and national systems continue, scientific research has little to fear.

Teleology is like a mistress to a biologist: he cannot live without her but he's unwilling to be seen with her in public.

Christianity is haunted by the theory of a God with a craving for bloody sacrifices.

I am quite sure that our views on evolution would be very different had biologists studied genetics and natural selection before and not after most of them were convinced that evolution had occurred.

If materialism is true, it seems to me that we cannot know that it is true. If my opinions are the result of the chemical processes going on in my brain, they are determined by the laws of chemistry, not those of logic.

I have come to the conclusion that my subjective account of my motivation is largely mythical on almost all occasions. I don't know why I do things.
