Stupidity and vulgarity

To discriminate schools, of art, of literature, is, of course, part of the obvious business of literary criticism: but, in the work of literary production, it is easy to be overmuch occupied concerning them. For, in truth, the legitimate contention is, not of one age or school of literary art against another, but of all successive schools alike, against the stupidity which is dead to the substance, and the vulgarity which is dead to the form.
