It is not conflict of opinions that has made history so violent but conflict of belief in opinions, that is to say conflict of convictions.

What if God were not exactly truth, and if this could be proved? And if he were instead the vanity, the desire for power, the ambitions, the fear, and the enraptured and terrified folly of mankind?

The higher man is distinguished from the lower by his fearlessness and his readiness to challenge misfortune.

The good-they cannot create; they are always the beginning of the end.

Do ask yourself why you, the individual, exist, and if you can get no other answer try for once to justify the meaning of your existence as it were a posteriori by setting before yourself an aim, a goal, a 'to this end', an exalted and noble 'to this end'.

And once you are awake, you shall remain awake eternally.

I am not a man, I am dynamite!
