Friedrich Nietzsche

Man does not strive for happiness

To live is to suffer

That the other suffers has to be learned

And just look at these men: their eye saith it - they know nothing better on earth than to be with a woman.Filth is at the bottom of their souls

All beings so far have created something beyond themselves

To recognize untruth as a condition of life--that certainly means resisting accustomed value feelings in a dangerous way

the voice of beauty speaks softly

The snake which cannot cast its skin has to die. As well the minds which are prevented from changing their opinions

He who would learn to fly one day must first learn to walk and run and climb and dance

one does not only wish to be understood when one writes

For nothing is more democratic than logic

Perhaps I know best why it is man alone who laughs

... first learn to construct the parts properly before it ventures to fashion a great whole

Solitude has seven skins

Youth is an unpleasant period

Association with other people corrupts our character

Moderation sees itself as beautiful
