[T]here is always something bodiless and without weight in [Nietzsche's] satire, simply because it has not any mass of common morality behind it. He is himself more preposterous than anything he denounces. But, indeed, Nietzsche will stand very well as the type of the whole of this failure of abstract violence. The softening of the brain which ultimately overtook him was not a physical accident. If Nietzsche had not ended in imbecility, Nietzscheism would end in imbecility. Thinking in isolation and with pride ends in being an idiot. Every man who will not have softening of the heart must at least have softening of the brain.
