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 DrydenBeauty, like ice, our footing does betray; Who can tread sure on the smooth, slippery way: Pleased with the surface, we glide swiftly on, And see the dangers that we cannot shun.
John Dryden
