In limiting poetry to the delineation of states of feeling, and denying the name where nothing is delineated but outward objects, we may be thought to have done what we promised to avoid--to have not found, but made a definition, in opposition to the usage of language, since it is established by common consent that there is a poetry called descriptive. We deny the charge. Description is not poetry because there is descriptive poetry, no more than science is poetry because there is such a thing as a didactic poem. But an object which admits of being described, or a truth which may fill a place in a scientific treatise, may also furnish an occasion for the generation of poetry, which we thereupon choose to call descriptive or didactic. The poetry is not in the object itself, nor in the scientific truth itself, but in the state of mind in which the one and the other may be contemplated. The mere delineation of the dimensions and colours of external objects is not poetry, no more than a geometrical ground-plan of St. Peter’s or Westminster Abbey is painting. Descriptive poetry consists, no doubt, in description, but in description of things as they appear, not as they are; and it paints them not in their bare and natural lineaments, but seen through the medium and arrayed in the colours of the imagination set in action by the feelings. If a poet describes a lion, he does not describe him as a naturalist would, nor even as a traveller would, who was intent upon stating the truth, the whole truth, and nothing but the truth. He describes him by imagery, that is, by suggesting the most striking likenesses and contrasts which might occur to a mind contemplating the lion, in the state of awe, wonder, or terror, which the spectacle naturally excites, or is, on the occasion, supposed to excite. Now this is describing the lion professedly, but the state of excitement of the spectator really. The lion may be described falsely or with exaggeration, and the poetry be all the better; but if the human emotion be not painted with scrupulous truth, the poetry is bad poetry, i. e. is not poetry at all, but a failure.
