The ascetic ideal has a goal—this goal is so universal that all the other interests of human existence seem, when compared with it, petty and narrow; it interprets epochs, nations, and men inexorably with a view to this one goal; it permits no other interpretation, no other goal
Nietzsche establishes the ascetic ideal’s totalizing interpretive dominance as the central problem: its universality reveals not strength but the absence of any rival will capable of opposing it.
