A discussion between Haldane and a friend began to take a predictable turn. The friend said with a sigh, 'It's no use going on. I know what you will say next, and I know what you will do next.' The distinguished scientist promptly sat down on the floor, turned two back somersaults, and returned to his seat. 'There,' he said with a smile. 'That's to prove that you're not always right.'

I have no doubt that in reality the future will be vastly more surprising than anything I can imagine. Now my own suspicion is that the Universe is not only queerer than we suppose, but queerer than we can suppose.

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

Haldane was engaged in discussion with an eminent theologian. "What inference," asked the latter, "might one draw about the nature of God from a study of his works?" Haldane replied: "An inordinate fondness for beetles."

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.

Science is vastly more stimulating to the imagination than the classics.
