Art upsets, science reasures.
In art, progress lies not in an extension, but in a knowledge of limitations.
Progress in art does not consist in reducing limitations, but in knowing them better.
Nature is a mere pretext for a decorative composition, plus sentiment. It suggests emotion, and I translate that emotion into art.
To define a thing is to substitute the definition for the thing itself.
I am much more interested in achieving unison with nature than in copying it.
