Foolish is my happiness, and foolish things will it speak: it is still too young—so have patience with it!

Man must become better and more evil.

The love of one sole being is a barbarism; for it will be employed to the detriment of all the rest. So too the love of God.

Discontent is the seed of ethics.

It is not when truth is dirty, but when it is shallow, that the lover of knowledge is reluctant to step into its waters.

Just as soon as we notice that someone has to force himself to pay attention when dealing and talking with us, we have a valid demonstration that he does not love us or that he does not love us anymore.

Man is something to be surpassed.
