For some reason today I read Fenimore Cooper's Literary Offenses by Mark Twain.
"A work of art? It has no invention; it has no order, system, sequence, or result; it has no lifelikeness, no thrill, no stir, no seeming of reality; its characters are confusedly drawn, and by their acts and words they prove that they are not the sort of people the author claims that they are; its humor is pathetic; its pathos is funny; its conversations are–oh! indescribable; its love-scenes odious; its English a crime against the language.
Counting these out, what is left is Art. I think we must all admit that."
