“It seems to me that self-renunciation and megalomania, however little they resemble one another apparently, may be observed successively, even simultaneously, in one and the same person. The ascetic, who has denied life and humbles himself before everybody, and the madman (like Nietzsche or Dostoevsky), who affirms that he is the light, the salt of the earth, the first in the whole world or even in the whole universe—both reach their madness—I hope there is no necessity to demonstrate that self- renunciation as well as megalomania is a kind of madness—under conditions for the most part identical.

All serious seeking brings a man to lonely paths, and lonely paths, it is well known, end in a great wall which sets a fatal bound to man's curiosity. Then arises the question, how shall a man pass beyond the wall, by overcoming either the law of impenetrability or the equally invincible law of gravity, in other words, how shall a man become infinitely small or infinitely great ?”
