There is an obstinacy against oneself, certain sublimated forms of which are included in asceticism. Certain kinds of men are under such a strong necessity of exercising their power and dominating impulses that, if other objects are lacking or if they have not succeeded with other objects they will actually tyrannize over some portions of their own nature or over sections and stages of their own personality. Thus do many thinkers bring themselves to views which are far from likely to increase or improve their fame. Many deliberately bring down the contempt of others upon themselves although they could easily have retained consideration by silence. Others contradict earlier opinions and do not shrink from the ordeal of being deemed inconsistent. On the contrary they strive for this and act like eager riders who enjoy horseback exercise most when the horse is skittish. Thus will men in dangerous paths ascend to the highest steeps in order to laugh to scorn their own fear and their own trembling limbs. Thus will the philosopher embrace the dogmas of asceticism, humility, sanctity, in the light of which his own image appears in its most hideous aspect. This crushing of self, this mockery of one's own nature, this spernere se sperni out of which religions have made so much is in reality but a very high development of vanity. The whole ethic of the sermon on the mount belongs in this category: man has a true delight in mastering himself through exaggerated pretensions or excessive expedients and later deifying this tyrannically exacting something within him. In every scheme of ascetic ethics, man prays to one part of himself as if it were god and hence it is necessary for him to treat the rest of himself as devil. 138
