I hope the clarity of the foregoing exposition will to some extent atone for it. II _Self-renunciation and Megalomania_ We are obliged to think that nothing certain can be said either of self-renunciation or of megalomania, though each one of us in his own experience knows something of the former as well as of the latter. But it is well known that the impossibility of solving a question never yet kept people from reflecting. On the contrary: to us the most alluring questions are those to which there is no actual, no universally valid, answer. I hope that sooner or later, philosophy will be thus defined, in contrast to science:--philosophy is the teaching of truths which are binding on none. Thereby the accusation so often made against philosophy will be removed, that philosophy properly consists of a series of mutually exclusive opinions. This is true, but she must be praised for it, not blamed: there is nothing bad in it, but good, a very great deal of good. On the other hand, it is bad, extremely bad, that science should consist of truths universally binding. For every obligation is a constraint. Temporarily, one can submit to a restraint, put on a corset, fetters; one can agree to anything temporarily. Rut who will voluntarily admit the mastery over himself of an eternal law? Even from the quiet and clear Spinoza I sometimes hear a deep sigh, and I think that he is longing for freedom--he who wasted all his life, all his genius in the glorification of necessity.... With such an introduction one may say what he pleases. 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. The world does not satisfy the man and he begins to seek for a better. 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? The first way is that of self-renunciation: I want nothing, I myself am nothing, I am infinitely small, and therefore I can pass through the infinitely small pores of the wall.
