QotD: "Even a single taboo can have an all-round crippling effect upon the mind, because there is always the danger that any thought which is freely followed up may lead to the forbidden thought."

"Even a single taboo can have an all-round crippling effect upon the mind, because there is always the danger that any thought which is freely followed up may lead to the forbidden thought. It follows that the atmosphere of totalitarianism [when fears, hatreds and loyalties of a directly political kind are always near to the surface of everyone's consciousness] is deadly to any kind of prose writer."
