It is hard for me to know what to paint. It comes slowly. - Edward Hopper

It's probably a reflection of my own, if I may say, loneliness. I don't know. It could be the whole human condition.

Great art is the outward expression of an inner life in the artist, and this inner life will result in his personal vision of the world. No amount of skillful invention can replace the essential element of imagination. One of the weaknesses of much abstract painting is the attempt to substitute the inventions of the intellect for a pristine imaginative conception. The inner life of a human being is a vast and varied realm and does not concern itself alone with stimulating arrangements of color, form, and design. The term "life" as used in art is something not to be held in contempt, for it implies all of existence, and the province of art is to react to it and not to shun it. Painting will have to deal more fully and less obliquely with life and nature's phenomena before it can again become great.

It is true that the Impressionists perhaps gave a more faithful representation of nature through their discoveries in out-of-door painting. But that they increased their statute as artists by so doing is controversial.. .If the technical innovations of the Impressionists led merely to a more accurate representation of nature, it was perhaps of not much value in enlarging their powers of expression.
