I like 'em thick: an apology to my English teachers

A writer apologizes to his English teachers for dismissing great literature as a hoax, after discovering 'thickness'—art that rewards attention—through Hieronymus Bosch's The Garden of Earthly Delights. He explores what makes art thick, from the butt music's hidden warning to Hokusai's iterative process, and argues that thickness is the essence separating true art from mere objects.
But thickness is tricky, because rewarding the careful reader often means repelling the casual one.
