An observation of the regular mode of the occurrence of this harmony, in the language of poetical minds, together with its relation to music, produced metre, or a certain system of traditional forms of harmony and language. Yet it is by no means essential that a poet should accomodate his language to this traditional form, so that the harmony which is its spirit, be observed. The practise is indeed convenient and popular and to be preferred, especially in such composition as includes much action: but every great poet must inevitably innovate upon the example of his predecessors in the exact structure of his peculiar versification. The distinction between poets and prose-writers is a vulgar error. The distinction between philosophers and poets has been anticipated. Plato was essentially a poet — the truth and splendour of his imagery and the melody of his language is the most intense that it is possible to conceive. He rejected the measure of the epic, dramatic and lyrical forms, because he sought to kindle a harmony in thoughts divested of shape and action, and he forebore to invent any regular plan of rhythm which would include under determinate forms, the varied pauses of his style. Cicero sought to imitate the cadence of his periods but with little success. Lord Bacon was a poet. His language has a sweet and majestic rhythm which satisfies the sense no less than the almost superhuman wisdom of his philosophy satisfies the intellect; it is a strain which distends, and then bursts the circumference of the readers' mind and pours itself forth together with it into the universal element with which it has perpetual sympathy. — All the Authors of revolutions in opinion are not only necessarily poets as they are inventors, nor even as their words unveil the permanent analogy of things by images which participate in the life of truth; but as their periods are harmonious and rhythmical and contain in themselves the elements of verse; being the echo of the eternal music. Nor are those supreme poets, who have employed traditional forms of rhythm on account of the form and action of their subjects, less incapable of perceiving and teaching the truth of things, than those who have omitted that form. Shakespear, Dante and Milton (to confine ourselves to modern writers.) are philosophers of the very loftiest powers.
But in periods of the decay of social life, the drama sympathizes with that decay. Tragedy becomes a cold imitation of the form of the great master-pieces of antiquity, divested of all harmonious accompaniment of the kindred arts; and often the very form misunderstood: or a weak attempt to teach certain doctrines, which the writer considers as moral truths; and which are usually no more than specious flatteries of some gross vice or weakness with which the author in common with his auditors are infected. Hence what has been called the classical and the domestic drama. Addison's Cato is a specimen of the one, and would it were not superfluous to cite examples of the other! To such purposes Poetry cannot be made subservient. Poetry is a sword of lightning ever unsheathed, which consumes the scabbard that would contain it. And thus we observe that all dramatic writings of this nature are unimaginative in a singular degree; they affect sentiment and passion: which divested of imagination are other names for caprice and appetite. The period in our own history of the greatest degradation of the drama is the reign of Charles II when all forms in which poetry had been accustomed to be expressed become hymns to the triumph of kingly power over liberty and virtue. Milton stood alone illuminating an age unworthy of him. At such periods the calculating principle pervades all the forms of dramatic exhibition, and poetry ceases to be expressed upon them. Comedy loses its ideal universality: wit succeeds to humour; we laugh from self complacency and triumph instead of pleasure; malignity, sarcasm & contempt succeeds to sympathetic merriment; we hardly laugh, but we smile. Obscenity, which is ever blasphemy against the divine beauty in life, becomes, from the very veil which it assumes, more active if less disgusting: it is a monster for which the corruption of society for ever brings forth new food; which it devours in secret.
The poetry of Dante may be considered as the bridge thrown over the stream of time which unites the modern and the antient world. The distorted notions of invisible things which Dante and his rival Milton have idealised, are merely the mask and the mantle in which these great poets walk through eternity enveloped and disguised. It is a difficult question to determine how far they were conscious of the distinction which must have subsisted in their minds between their own creeds and that of the people. Dante at least appears to wish to mark the full extent of it by placing Riphæus whom Virgil calls justissimus unus in Paradise, and observing a most heretical caprice in his distribution of rewards and punishments. And Milton's poem contains within itself a philosophical refutation of that system of which, by a strange and natural antithesis, it has been a chief popular support. Nothing can exceed the energy and magnificence of the character as expressed in Paradise Lost. It is a mistake to suppose that he could ever have been intended for the popular personification of evil. Implacable hate, patient cunning, and a sleepless refinement of device to inflict the extremest anguish on an enemy, these things are evil; and although venial in a slave are not to be forgiven in a tyrant; although redeemed by much that ennobles his defeat in one subdued, are marked by all that dishonours his conquest in the victor. Milton's Devil as a moral being is as far superior to his God as one who perseveres in some purpose which he has conceived to be excellent in spite of adversity and torture, is to one who in the cold security of undoubted triumph inflicts the most horrible revenge upon his enemy — not from any mistaken notion of inducing him to repent of a perseverance in enmity, but with the alledged design of exasperating him to deserve new torments. Milton has so far violated the popular creed (if this shall be judged to be a violation) as to have alledged no superiority of moral virtue to his God over his Devil. And this bold neglect of a direct moral purpose is the most decisive proof of the supremacy of Milton's genius. He mingled as it were the elements of human nature, as colours upon a single pallet, and arranged them into the composition of his great picture according to the laws of epic truth; that is, according to the laws of that principle by which a series of actions of the external universe, and of intelligent and ethical beings is calculated to excite the sympathy of succeeding generations of mankind. The Divina Comedia, and Paradise Lost have conferred upon modern mythology a systematic form; and when change and time shall have added one more superstition to the mass of those which have arisen and decayed upon the earth, commentators will be learnedly employed in elucidating the religion of ancestral Europe, only not utterly forgotten because it will have been stamped with the eternity of genius.
