=For Tranquility.=--But will not our philosophy become thus a tragedy? Will not truth prove the enemy of life, of betterment? A question seems to weigh upon our tongue and yet will not put itself into words: whether one _can_ knowingly remain in the domain of the untruthful? or, if one _must_, whether, then, death would not be preferable? For there is no longer any ought (Sollen), morality; so far as it is involved "ought," is, through our point of view, as utterly annihilated as religion. Our knowledge can permit only pleasure and pain, benefit and injury, to subsist as motives. But how can these motives be distinguished from the desire for truth? Even they rest upon error (in so far, as already stated, partiality and dislike and their very inaccurate estimates palpably modify our pleasure and our pain). The whole of human life is deeply involved in _untruth_. The individual cannot extricate it from this pit without thereby fundamentally clashing with his whole past, without finding his present motives of conduct, (as that of honor) illegitimate, and without opposing scorn and contempt to the ambitions which prompt one to have regard for the future and for one's happiness in the future. Is it true, does there, then, remain but one way of thinking, which, as a personal consequence brings in its train despair, and as a theoretical [consequence brings in its train] a philosophy of decay, disintegration, self annihilation? I believe the deciding influence, as regards the after-effect of knowledge, will be the _temperament_ of a man; I can, in addition to this after-effect just mentioned, suppose another, by means of which a much simpler life, and one freer from disturbances than the present, could be lived; so that at first the old motives of vehement passion might still have strength, owing to hereditary habit, but they would gradually grow weaker under the influence of purifying knowledge. A man would live, at last, both among men and unto himself, as in the natural state, without praise, reproach, competition, feasting one's eyes, as if it were a play, upon much that formerly inspired dread. One would be rid of the strenuous element, and would no longer feel the goad of the reflection that man is not even [as much as] nature, nor more than nature. To be sure, this requires, as already stated, a good temperament, a fortified, gentle and naturally cheerful soul, a disposition that has no need to be on its guard against its own eccentricities and sudden outbreaks and that in its utterances manifests neither sullenness nor a snarling tone--those familiar, disagreeable characteristics of old dogs and old men that have been a long time chained up. Rather must a man, from whom the ordinary bondages of life have fallen away to so great an extent, so do that he only lives on in order to grow continually in knowledge, and to learn to resign, without envy and without disappointment, much, yes nearly everything, that has value in the eyes of men.
