Friedrich Nietzsche

He who laughs best today, will also laughs last.

The best author will be the one who is ashamed to become a writer.

In the last analysis, even the best man is evil: in the last analysis, even the best woman is bad.

The best weapon against an enemy is another enemy.

Perhaps I know best why it is man alone who laughs he alone suffers so deeply that he had to invent laughter.
