Never strive, O artist, to create what you are not irresistibly impelled to create!

New happiness too must be learned to bear.

Not reading a beautiful book again because you've already read it, that is, as if you were not visiting a dear friend again because you know him already.

Many a truth is the result of an error.

A book cannot easily be too bad for the general public, but may easily be too good.

Little evil would be done in the world if evil never could be done in the name of good.

Those who know nothing must believe everything.
