But if this should be admitted as a satisfactory character of a poem, we have still to seek for a definition of poetry. The writings of Plato and Bishop Taylor, and the _Theoria Sacra_ of Burnet, furnish undeniable proofs that poetry of the highest kind may exist without metre, and even without the contradistinguishing objects of a poem. The first chapter of Isaiah (indeed a very large proportion of the whole book) is poetry in the most emphatic sense; yet it would be not less irrational than strange to assert that pleasure, and not truth, was the immediate object of the prophet. In short, whatever specific import we attach to the word poetry, there will be found involved in it, as a necessary consequence, that a poem of any length neither can be, nor ought to be, all poetry. Yet if a harmonious whole is to be produced, the remaining parts must be preserved in keeping with the poetry; and this can be no otherwise effected than by such a studied selection and artificial arrangement as will partake of one, though not a peculiar, property of poetry. And this again can be no other than the property of exciting a more continuous and equal attention than the language of prose aims at, whether colloquial or written. My own conclusions on the nature of poetry, in the strictest use of the word, have been in part anticipated in the preceding disquisition on the fancy and imagination. What is poetry? is so nearly the same question with, what is a poet? that the answer to the one is involved in the solution of the other. For it is a distinction resulting from the poetic genius itself, which sustains and modifies the images, thoughts, and emotions of the poet's own mind. The poet, described in ideal perfection, brings the whole soul of man into activity, with the subordination of its faculties to each other, according to their relative worth and dignity. He diffuses a tone and spirit of unity that blends, and (as it were) fuses, each into each, by that synthetic and magical power to which we have exclusively appropriated the name of imagination. This power, first put in action by the will and understanding, and retained under their irremissive, though gentle and unnoticed, control (_laxis effertur habenis_), reveals itself in the balance or reconciliation of opposite or discordant qualities: of sameness, with difference; of the general, with the concrete; the idea, with the image; the individual, with the representative; the sense of novelty and freshness, with old and familiar objects; a more than usual state of emotion, with more than usual order; judgment ever awake and steady self-possession, with enthusiasm and feeling profound or vehement; and while it blends and harmonizes the natural and the artificial, still subordinates art to nature, the manner to the matter, and our admiration of the poet to our sympathy with the poetry.
