In a play, certainly, the subject is of more importance than in any other work of art. Infelicity, triviality, vagueness of subject, may be outweighed in a poem, a novel, or a picture, by charm of manner, by ingenuity of execution; but in a drama the subject is of the essence of the work-it is the work. If it is feeble, the work can have no force; if it is shapeless, the work must be amorphous.
