But let us not be betrayed from a defence into a critical history of poetry and its influence on society. Be it enough to have pointed out the effects of poets, in the large and true sense of the word, upon their own and all succeeding times.
But poets have been challenged to resign the civic crown to reasoners and mechanists, on another plea. It is admitted that the exercise of the imagination is most delightful, but it is alleged that that of reason is more useful. Let us examine as the grounds of this distinction what is here meant by utility. Pleasure or good, in a general sense, is that which the consciousness of a sensitive and intelligent being seeks, and in which, when found, it acquiesces. There are two kinds of pleasure, one durable, universal, and permanent; the other transitory and particular. Utility may either express the means of producing the former or the latter. In the former sense, whatever strengthens and purifies the affections, enlarges the imagination, and adds spirit to sense, is useful. But a narrower meaning may be assigned to the word utility, confining it to express that which banishes the importunity of the wants of our animal nature, the surrounding, men with security of life, the dispersing the grosser delusions of superstitions, and the conciliating such a degree of mutual forbearance among men as may consist with the motives of personal advantage.
Undoubtedly the promoters of utility, in this limited sense, have their appointed office in society. They follow the footsteps of poets, and copy the sketches of their creations into the book of common life. They make space, and give time. Their exertions are of the highest value, so long as they confine their administration of the concerns of the inferior powers of our nature within the limits due to the superior ones. But whilst the sceptic destroys gross superstitions, let him spare to deface, as some of the French writers have defaced, the eternal truths charactered upon the imaginations of men. Whilst the mechanist abridges, and the political economist combines labor, let them beware that their speculations, for want of correspondence with those first principles which belong to the imagination, do not tend, as they have in modern England, to exasperate at once the extremes of luxury and want. They have exemplified the saying, “To him that hath, more shall be given; and from him that hath not, the little that he hath shall be taken away.” The rich have become richer, and the poor have become poorer; and the vessel of the State is driven between the Scylla and Charybdis of anarchy and despotism. Such are the effects which must ever flow from an unmitigated exercise of the calculating faculty.
It is difficult to define pleasure in its highest sense; the definition involving a number of apparent paradoxes. For, from an inexplicable defect of harmony in the constitution of human nature, the pain of the inferior is frequently connected with the pleasures of the superior portions of our being. Sorrow, terror, anguish, despair itself, are often the chosen expressions of an approximation to the highest good. Our sympathy in tragic fiction depends on this principle; tragedy delights by affording a shadow of the pleasure which exists in pain. This is the source also of the melancholy which is inseparable from the sweetest melody. The pleasure that is in sorrow is sweeter than the pleasure of pleasure itself. And hence the saying, “It is better to go to the house of mourning than to the house of mirth.” Not that this highest species of pleasure is necessarily linked with pain. The delight of love and friendship, the ecstasy of the admiration of nature, the joy of the perception and still more of the creation of poetry, is often wholly unalloyed.
The production and assurance of pleasure in this highest sense is true utility. Those who produce and preserve this pleasure are poets or poetical philosophers.
The exertions of Locke, Hume, Gibbon, Voltaire, Rousseau [although Rousseau has been thus classed, he was essentially a poet. The others, even Voltaire, were mere reasoners.—Shelley’s note], and their disciples, in favor of oppressed and deluded humanity, are entitled to the gratitude of mankind. Yet it is easy to calculate the degree of moral and intellectual improvement which the world would have exhibited, had they never lived. A little more nonsense would have been talked for a century or two; and perhaps a few more men, women, and children burnt as heretics. We might not at this moment have been congratulating each other on the abolition of the Inquisition in Spain. But it exceeds all imagination to conceive what would have been the moral condition of the world if neither Dante, Petrarch, Boccaccio, Chaucer, Shakespeare, Calderon, Lord Bacon, nor Milton, had ever existed; if Raphael and Michael Angelo had never been born; if the Hebrew poetry had never been translated; if a revival of the study of Greek literature had never taken place; if no monuments of ancient sculpture had been handed down to us; and if the poetry of the religion of the ancient world had been extinguished together with its belief. The human mind could never, except by the intervention of these excitements, have been awakened to the invention of the grosser sciences, and that application of analytical reasoning to the aberrations of society, which it is now attempted to exalt over the direct expression of the inventive and creative faculty itself.
