Live so that thou mayest desire to live again - that is thy duty - for in any case thou wilt live again!

A reader is doubly guilty of bad manners against an author when he praises his second book at the expense of his first (or vice versa) and then expects the author to be grateful for what he has done.

You say 'I' and you are proud of this word. But greater than this- although you will not believe in it - is your body and its great intelligence, which does not say 'I' but performs 'I'.

Strength is the morality of the man who stands out from the rest, and it is mine.

For such is man: a Theological Dogma might be refuted to him a thousand times - provided however, that he had need of it, he would again and again accept it as true. Belief is always most desired, most pressingly needed where there is a lack of will. Fanaticism is the sole "volitional strength" to which the weak and irresolute can be excited, as a sort of hypnotising of the entire sensory-intellectual system.

The coward does not know what it means to be alone: an enemy is always standing behind his chair.

That is the most extreme form of nihilism: nothingness (the "meaningless") eternally!
