Who has not for the sake of his reputation sacrificed himself?

The charm of knowledge would be small indeed, were it not that there is so much shame to be overcome on the way to it.

And he who must be a creator in good and evil: verily, he must be an annihilator first and demolish values.

We have no organ at all for knowledge, for truth: we know (or believe or imagine) precisely as much as may be useful in the interest of the human herd, the species: and even what is here called usefulness is in the end only a belief, something imagined and perhaps precisely that most fatal piece of stupidity by which we shall one day perish.

Not with wrath do we kill, but with laughter. Come, let us kill the spirit of gravity!

This crown to crown the laughing man, this rose-wreath crown: I myself have set this crown upon my head, I myself have pronounced my laughter holy.
