The Self–Renouncer. What does the self-renouncer do? He strives after a higher world, he wants to fly longer and further and higher than all men of affirmation he throws away many things that would impede his flight, and several things among them that are not valueless, that are not unpleasant to him: he sacrifices them to his desire for elevation. Now this sacrificing, this casting away, is the very thing which becomes visible in him: on that account one calls him a self-renouncer, and as such he stands before us, enveloped in his cowl, and as the soul of a hair-shirt. With this effect, however, which he makes upon us he is well content: he wants to keep concealed from us his desire, his pride, his intention of flying above us. Yes! He is wiser than we thought, and so courteous towards us this affirmer! For that is what he is, like us, even in his self-renunciation.
