Art is constitutive-the artist determines beauty. He does not take it over.

He is happiest, be he king or peasant, who finds peace in his home.

A state of true and universal tolerance is best ensured by leaving alone the peculiarities of men and peoples.

It is easier to perceive error than to find truth, for the former lies on the surface and is easily seen, while the latter lies in the depth, where few are willing to search for it.

No one can take from us the joy of the first becoming aware of something, the so-called discovery. But if we also demand the honor, it can be utterly spoiled for us, for we are usually not the first. What does discovery mean, and who can say that he has discovered this or that? After all it's pure idiocy to brag about priority; for it's simply unconscious conceit, not to admit frankly that one is a plagiarist.

It is in human nature to relax, when not compelled by personal advantage or disadvantage.

As soon as you trust yourself, you will know how to live.
