I just read a NY TIMES review of the book "Shadows Bright As Glass" about the strange but true tale of Jon Sarkin, a middle-aged chiropractor who, after having a stroke, becomes a prolific and successful artist. (http://jsarkin.com/art/)
Sarkin's obsessive artistic output seems to function as an outlet for thoughts and feelings he cannot otherwise express – art that springs from the same reflex that inspired the first cave painting.
So I was not surprised to read of Dr. Sarkin’s response to a fan who asked him what his art meant. “It doesn’t mean anything,” he said. “You want meaning? Go get The Wall Street Journal.”
