All credibility, all good conscience, all evidence of truth come only from the senses.

A good writer possesses not only his own spirit but also the spirit of his friends.

I do not know what the spirit of a philosopher could more wish to be than a good dancer. For the dance is his ideal, also his fine art, finally also the only kind of piety he knows, his 'divine service.'

Many a man fails as an original thinker simply because his memory it too good.

It is good to express a thing twice right at the outset and so to give it a right foot and also a left one. Truth can surely stand on one leg, but with two it will be able to walk and get around.
