One of the two is almost always a prevailing tendency of every author: either not to say some things which certainly should be said, or to say many things which did not need to be said. The first is the original sin of synthetic natures, the latter of analytical natures.

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.

Religion is not only a part of education, an element of humanity, but the center of everything else, always the first and the ultimate, the absolutely original.

The two basic maxims of the so-called historical criticism are the postulate of the common and the axiom of the ordinary. Postulate of the common: everything really great, good, and beautiful, is improbable, since it is extraordinary and therefore at least suspect. Axiom of the ordinary: our conditions and environment must have existed everywhere, for they are really so natural.

Reason is mechanical, wit chemical, and genius organic spirit.

One has only as much morality as one has philosophy and poetry.

Whoever does not philosophize for the sake of philosophy, but rather uses philosophy as a means, is a sophist.
