A genuinely free and educated man should be able to tune himself, as one tunes a musical instrument, absolutely arbitrarily, at his convenience at any time and to any degree, philosophically or philologically, critically or poetically, historically or rhetorically, in ancient or modern form.

About no subject is there less philosophizing than about philosophy.

Where there is politics or economics, there is no morality.

Religion and morals are symmetrically opposed, just like poetry and philosophy.

Every uneducated person is a caricature of himself.

The genuine priest always feels something higher than compassion.

Morality without a sense of paradox is mean.
