Shakespeare, Ben Jonson, Beaumont and Fletcher

Poetry is not the proper antithesis to prose, but to science. Poetry is opposed to science, and prose to meter. The proper and immediate object of science is the acquirement, or communication, of truth; the proper and immediate object of poetry is the communication of immediate pleasure. This definition is useful; but as it would include novels and other works of fiction, which yet we do not call poems, there must be some additional character by which poetry is not only divided from opposites, but likewise distinguished from disparate, though similar, modes of composition. Now how is this to be effected? In animated prose, the beauties of nature, and the passions and accidents of human nature, are often expressed in that natural language which the contemplation of them would suggest to a pure and benevolent mind; yet still neither we nor the writers call such a work a poem, though no work could deserve that name which did not include all this, together with something else. What is this? It is that pleasurable emotion, that peculiar state and degree of excitement, which arises in the poet himself in the act of composition and in order to understand this, we must combine a more than ordinary sympathy with the objects, emotions, or incidents contemplated by the poet, consequent on a more than common sensibility, with a more than ordinary activity of the mind in respect of the fancy and the imagination.
