“…ignoring the potential force possessed by a homogeneous race, bemused by the slogans of human equality, all parliaments adopted the dogma of infinite toleration. Tolerance toward the alien, the hostile, and the aggressive was seen as a highly humanitarian achievement, but was, as the history of the nineteenth and especially of our present century shows, merely an ever-greater abandoning of ourselves.”

What I Believe (1938)
Context: I do not believe in Belief. But this is an Age of Faith, and there are so many militant creeds that, in self defence, one has to formulate a creed of one's own. Tolerance, good temper and sympathy are no longer enough in a world where ignorance rules, and Science, which ought to have ruled, plays the pimp. Tolerance, good temper and sympathy — they are what matter really, and if the human race is not to collapse they must come to the front before long.
