My formula for greatness in a human being is amor fati: that one wants nothing to be other than it is, not in the future, not in the past, not in all eternity.
Without the errors involved in the assumptions of ethics, man would have remained an animal. Thus has he taken himself as something higher and imposed rigid laws upon himself.
A degree of culture, and assuredly a very high one, is attained when man rises above superstitions and religious notions and fears, and, for instance, no longer believes in guardian angels or in original sin, and has also ceased to talk of the salvation of his soul.
How much rationality and higher protection there is in such self-deception, and how much falseness I still require in order to allow myself again and again the luxury of my sincerity.
That the world is not the embodiment of an eternal rationality can be conclusively proved by the fact that the piece of the worldthat we know--I mean our human reason--is not so very rational. And if it is not eternally and completely wise and rational, then the rest of the world will not be either; here the conclusion a minori ad majus, a parte ad totum applies, and does so with decisive force.
Probability but no truth, facility but no freedom--it is owing to these two fruits that the tree of knowledge cannot be confused with the tree of life.
As is well known, the priests are the most evil enemies—but why? Because they are the most impotent. It is because of their impotence that in them hatred grows to monstrous and uncanny proportions, to the most spiritual and poisonous kind of hatred. The truly great haters in world history have always been priests; likewise the most ingenious haters: other kinds of spirit hardly come into consideration when compared with the spirit of priestly vengefulness.
Here is a hero who did nothing but shake the tree as soon as the fruit was ripe. Does this seem to be too small a thing to you? Then take a good look at the tree he shook.
All human life is sunk deep in untruth; the individual cannot pull it out of this well without growing profoundly annoyed with his entire past, without finding his present motives (like honor) senseless, and without opposing scorn and disdain to the passions that urge one on to the future and to the happiness in it.
