“The materialist is sure that history has been simply and solely a chain of causation, just as the [lunatic] is quite sure that he is simply and solely a chicken. Materialists and madmen never have doubts.”

“The Christian admits that the universe is manifold and even miscellaneous, just as a sane man knows that he is complex. The sane man knows that he has a touch of the beast, a touch of the devil, a touch of the saint, a touch of the citizen. Nay, the really sane man knows that he has a touch of the madman. But the materialist's world is quite simple and solid, just as the madman is quite sure he is sane. The materialist is sure that history has been simply and solely a chain of causation, just as the interesting person before mentioned is quite sure that he is simply and solely a chicken. Materialists and madmen never have doubts.”

“The materialist theory of history, that all politics and ethics are the expression of economics, is a very simple fallacy indeed. It consists simply of confusing the necessary conditions of life with the normal preoccupations of life, that are quite a different thing. It is like saying that because a man can only walk about on two legs, therefore he never walks about except to buy shoes and stockings.”

“The modern materialist often makes it simply: "Do what you like," and then rushes off to ask his psychoanalyst when he no longer likes anything.”

“The modern materialists are not permitted to doubt; they are forbidden to believe.”

“A materialistic world will not be won to Christ by a materialistic church.”
