The poetical element may find expression either in prose or verse. The “Undine” of Fouqué is poetical, but it is not poetry. A prose writer may have imagination and fancy in abundance and yet not be a poet. What is it, then, that peculiarly distinguishes the poet? It is not merely a sense of the beautiful, but so much keener _joy_ in the sense of it (arising from a greater fineness of organization) that the emotion must _sing_, instead of only _speaking_ itself. The first great distinction of poetry is _form_ or arrangement. This is not confined to poems alone, but is found involved with the expression of the poetical in all the Arts. It is here that the statue bids good-bye to anatomy and passes beyond it into the region of beauty; that the painter passes out of the copyist and becomes the Artist. Mr. Lowell here quoted Spenser’s statement of Plato’s doctrine: For of the soul the body form doth take, For soul is form and doth the body make. This coördination of the spirit and form of a poem is especially remarkable in the “Divina Commedia” of Dante and the “Paradise Lost” of Milton, and that not only in the general structure, but in particular parts. The lines of Dante seem to answer his every mood: sometimes they have the compressed implacability of his lips, sometimes they ring like an angry gauntlet thrown down in defiance, and sometimes they soften or tremble as if that stern nature would let its depth of pity show itself only in a quiver of the voice; but always and everywhere there is subordination, and the pulse of the measure seems to keep time to the footfall of the poet along his fated path, as if a fate were on the verses too. And so in the “Paradise Lost” not only is there the pomp of long passages that move with the stately glitter of Milton’s own angelic squadrons, but if you meet anywhere a single verse, that, too, is obstinately epic, and you recognize it by its march as certainly as you know a friend by his walk. The instinctive sensitiveness to order and proportion, this natural incapability of the formless and vague, seems not only natural to the highest poetic genius, but to be essential to the universality and permanence of its influence over the minds of men. The presence of it makes the charm of Pope’s “Rape of the Lock” perennial; its absence will always prevent such poems as the “Faëry Queene,” “Hudibras,” and the “Excursion” (however full of beauty, vivacity, and depth of thought) from being popular. Voltaire has said that epic poems were discourses which at first were written in verse only because it was not yet the custom to narrate in prose. But instead of believing that verse is an imperfect and undeveloped prose, it seems much more reasonable to conclude it the very consummation and fortunate blossom of speech, as the flower is the perfection towards which the leaf yearns and climbs, and in which it at last attains to fullness of beauty, of honey, of perfume, and the power of reproduction.
