Where two principles really do meet which cannot be reconciled with one another, then each man declares the other a fool and a heretic

I am sitting with a philosopher in the garden; he says again and again 'I know that that’s a tree', pointing to a tree that is near us. Someone else arrives and hears this, and I tell him: 'This fellow isn’t insane. We are only doing philosophy.

I sit astride life like a bad rider on a horse. I only owe it to the horse's good nature that I am not thrown off at this very moment.

Philosophy limits the thinkable and therefore the unthinkable.

I am my world.

Talent is a spring from which fresh water always flows.- But this spring is worthless if no good use is made of it.

A philosopher always finds more grass to feed upon in the valleys of stupidity than on the arid heights of intelligence.
