Nietzsche on the virtues of renegacy and apostasy

Friedrich Nietzsche

how little, to him, does the changing of an opinion seem contemptible per se! On the contrary, how highly he prizes the ability to change an opinion as a rare and valuable distinction, especially if he can retain it far into old age! And his pride (not his pusillanimity) even reaches so high as to be able to pluck the fruits of the spernere se sperni and the spernere se ipsum: without his being troubled by the sensation of fear of vain and easy-going men. Furthermore, the doctrine of the innocence of all opinions appears to him to be as certain as the doctrine of the innocence of all actions: how could he act as judge and hangman before the apostate of intellectual liberty! On the contrary, the sight of such a person would disgust him as much as the sight of a nauseous illness disgusts the physician: the physical repulsion caused by everything spongy, soft, and suppurating momentarily overcomes reason and the desire to help. Hence our goodwill is overcome by the conception of the monstrous dishonesty which must have gained the upper hand in the apostate from the free spirit: by the conception of a general gnawing which is eating its way down even to the framework of the character.-Aphorism 56, The Dawn of Daybreak
