What does Szarkowski write about art in general?

In general, Szarkowski believes art is mainly consisted of form.  He even says, "form is perhaps the point of art."  With form, nothing is in the boundaries of nonfiction or based on fact.  "The goal is not to make something factually impeccable, but seamlessly persuasive."  And, if anything, in art, the subject is not the "starting point" but, instead, the overall "destination".
