Painting is founded on the heart controlled by the head.
The painter must enclose himself within his work; he must respond not with words, but with paintings.
The artist must scorn all judgment that is not based on an intelligent observation of character. He must beware of the literary spirit which so often causes a painting to deviate from its true path - the concrete study of nature - to lose itself all too long in intangible speculations.
If isolation tempers the strong, it is the stumbling-block of the uncertain.
It's so fine and yet so terrible to stand in front of a blank canvas.
The truth is in nature, and I shall prove it.
