Bertrand Russell on Immanuel Kant

“[T]here used to be in the old days three intellectual arguments for the existence of God, all of which were disposed of by Immanuel Kant in the Critique of Pure Reason; but no sooner had he disposed of those arguments than he invented a new one, a moral argument, and that quite convinced him. He was like many people: in intellectual matters he was skeptical, but in moral matters he believed implicitly in the maxims that he had imbibed at his mother's knee. That illustrates what the psychoanalysts so much emphasize — the immensely stronger hold upon us that our very early associations have than those of later times.”

“From childish fear springs the desire to externalise the ego. Metaphysicians do this in thought: Kant, who, in real life, never went more than ten miles from his native city of Königsberg, maintained that the whole of space existed only in his imagination. This grandiose philosophy was merely the obverse of his practical timidity.”
