Truth is the daughter of time, not of authority.

The colors that show best by candlelight are white, carnation, and a kind of sea-water green.

Truth comes out of error more readily than out of confusion.

You see, painting has now become, or all art has now become completely a game, by which man distracts himself. What is fascinating actually is, that it's going to become much more difficult for the artist, because he must really deepen the game to become any good at all.

I feel ever so strongly that an artist must be nourished by his passions and his despairs. These things alter an artist whether for the good or the better or the worse. It must alter him. The feelings of desperation and unhappiness are more useful to an artist than the feeling of contentment, because desperation and unhappiness stretch your whole sensibility.

The poets did well to conjoin music and medicine, in Apollo, because the office of medicine is but to tune the curious harp of man's body and reduce it to harmony.

Studies perfect nature and are perfected still by experience.
