Imagination in a poet is a faculty so wild and lawless that, like a high ranging spaniel, it must have clogs tied to it, lest it outrun the judgment. The great easiness of blank verse renders the poet too luxuriant. He is tempted to say many things which might better be omitted, or, at least shut up in fewer words.
John DrydenHe was the man who of all modern, and perhaps ancient poets, had the largest and most comprehensive soul. . . . He was naturally learn'd; he needed not the spectacles of books to read Nature; he looked inwards, and found her there. . . . He is many times flat, insipid; his comic wit degenerating in to clenches, his serious swelling into bombast. But he is always great, when some occasion is presented to him.
John Dryden
