There is nothing ugly in art except that which is without character, that is to say, that which offers no outer or inner truth.

To the artist there is never anything ugly in nature

The realities of nature surpass our most ambitious dreams.

To any artist, worthy of the name, all in nature is beautiful, because his eyes, fearlessly accepting all exterior truth, read there, as in an open book, all the inner truth.

There should be no argument in regard to morality in art. There is no morality in nature.

Love your calling with passion, it is the meaning of your life.

True artists are almost the only men who do their work for pleasure.
