The calamity of madness did no harm to Nietzsche’s burgeoning reputation: he came to fame as the philosopher who denounced the demands of reason so effectively that at last he lost his own. Twilight could now be seen as foreshadowing the eclipse of an intellect of such power that no one could stand it, even himself, and Zarathustra became a record of insights too deep to be expressed in the ordinary discourse of reason...
