All philosophy is a form of confession.

The unselective knowledge drive resembles the indiscriminate sexual drive--signs of vulgarity!

You want to be paid as well, you virtuous! You want reward for virtue, and heaven for earth, and eternity for your today?

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.

What is the truth, but a lie agreed upon.

One must never have spared oneself, one must have acquired hardness as a habit to be cheerful and in good spirits in the midst of nothing but hard truths.

The belief in authority is the source of conscience; which is therefore not the voice of God in the heart of man, but the voice of some men in man.
