"Progressive art can assist people to learn not only about the objective forces at work in the society in which they live, but alsoabout the intensely social character of their interior lives. Ultimately, it can propel people toward social emancipation."
"Fine art, that exists for itself alone, is art in a final state of impotence. If nobody, including the artist, acknowledges art asa means of knowing the world, then art is relegated to a kind of rumpus room of the mind and the irresponsibility of the artist and the irrelevance of art to actual living becomes part and parcel of the practice of art."
"There is a conceptual depth as well as a purely visual depth. The first is discovered by science; the second is revealed in art. The first aids us in understanding the reasons of things; the second in seeing their forms. In science we try to trace phenomena back to their first causes, and to general laws and principles. In art we are absorbed in their immediate appearance, and we enjoy this appearance to the fullest extent in all its richness and variety. Here we are not concerned with the uniformity of laws but with the multiformity and diversity of intuitions."
