Conversation with a friend will only bear good fruit of knowledge when both think only of the matter under consideration and forget that they are friends.
Every virtue inclines to stupidity, every stupidity to virtue; "stupid to the point of sanctity," they say in Russia, - let us be careful lest out of pure honesty we eventually become saints and bores!
All philosophers make the common mistake of taking contemporary man as their starting point and of trying, through an analysis of him, to[21] reach a conclusion. "Man" involuntarily presents himself to them as an aeterna veritas as a passive element in every hurly-burly, as a fixed standard of things. Yet everything uttered by the philosopher on the subject of man is, in the last resort, nothing more than a piece of testimony concerning man during a very limited period of time.
Man is at his furthest remove from the animal as a child, his intellect most human. With his fifteenth year and puberty he comes astep closer to the animal; with the sense of possessions of his thirties (the median line between laziness and greediness), still another step. In his sixtieth year of life he frequently loses his modesty as well, then the septuagenarian steps up to us as a completely unmasked beast: one need only look at the eyes and the teeth.
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.
We think that play and fairytales belong to childhood - how shortsighted that is! As though we would want at any time in our life to live without play and fairytales! We give these things other names, to be sure, and feel differently about them, but precisely this is the evidence that they are the same things, for the child too regards play as his work and fairy tales as his truth. The brevity of life ought to preserve us from a pedantic division of life into different stages - as though each brought something new.
