Every philosophical review ought to be a philosophy of reviews at the same time.

Morality without a sense of paradox is mean.

As long as the artist invents and is inspired, he remains in a constrained state of mind, at least for the purpose of communication. He then wants to say everything, which is the wrong tendency of young geniuses or the right prejudice of old bunglers. Thus, he fails to recognize the value and dignity of self-restraint, which is indeed for both the artist and the man the first and the last, the most necessary and the highest goal.

All the classical genres are now ridiculous in their rigorous purity.

In many a poetic work, one gets here and there, instead of representation merely a title indicating that this or that was supposedto be represented here, that the artist has been prevented from doing it and most humbly asks to be kindly excused.

If you want to penetrate into the heart of physics, then let yourself be initiated into the mysteries of poetry.

The main thing is to know something and to say it.
