Poetry then is an imitation of nature, but the imagination and the passions are a part of man's nature. We shape things according to our wishes and fancies, without poetry; but poetry is the most emphatical language that can be found for those creations of the mind "which ecstacy is very cunning in." Neither a mere description of natural objects, nor a mere delineation of natural feelings, however distinct or forcible, constitutes the ultimate end and aim of poetry, without the heightenings of the imagination. The light of poetry is not only a direct but also a reflected light, that while it shows us the object, throws a sparkling radiance on all around it: the flame of the passions, communicated to the imagination, reveals to us, as with a flash of lightning, the inmost recesses of thought, and penetrates our whole being. Poetry represents forms chiefly as they suggest other forms; feelings, as they suggest forms or other feelings. Poetry puts a spirit of life and motion into the universe. It describes the flowing, not the fixed. It does not define the limits of sense, or analyze the distinctions of the understanding, but signifies the excess of the imagination beyond the actual or ordinary impression of any object or feeling. The poetical impression of any object is that uneasy, exquisite sense of beauty or power that cannot be contained within itself; that is impatient of all limit; that (as flame bends to flame) strives to link itself to some other image of kindred beauty or grandeur; to enshrine itself, as it were, in the highest forms of fancy, and to relieve the aching sense of pleasure by expressing it in the boldest manner, and by the most striking examples of the same quality in other instances. Poetry, according to Lord Bacon, for this reason "has something divine in it, because it raises the mind and hurries it into sublimity, by conforming the shows of things to the desires of the soul, instead of subjecting the soul to external things, as reason and history do." It is strictly the language of the imagination; and the imagination is that faculty which represents objects, not as they are in themselves, but as they are moulded by other thoughts and feelings, into an infinite variety of shapes and combinations of power. This language is not the less true to nature, because it is false in point of fact; but so much the more true and natural, if it conveys the impression which the object under the influence of passion makes on the mind. Let an object, for instance, be presented to the senses in a state of agitation or fear--and the imagination will distort or magnify the object, and convert it into the likeness of whatever is most proper to encourage the fear. "Our eyes are made the fools" of our other faculties. This is the universal law of the imagination, "That if it would but apprehend some joy, It comprehends some bringer of that joy: Or in the night imagining some fear, How easy is a bush suppos'd a bear!"
