What am I missing in art?

“For me, a consequence of my drawing was a new appreciation of the visual arts. When possible, I would study a painting’s content-⎯that is, its cultural, social, and historical context⎯which enhanced my artistic appreciation and understanding. But I came to realize that my relative neglect of form⎯the internal dialogue brushed into the canvas or carved in the sculpture⎯had deprived me of a fuller aesthetic experience of art.”

-J.R. Leibowitz, Hidden Harmony, The Connected Worlds of Physics and Art
