"A Defence of Poetry" is an essay by the English poet Percy Bysshe Shelley, written in 1821 and first published posthumously in 1840 in Essays, Letters from Abroad, Translations and Fragments by Edward Moxon in London. It contains Shelley's famous claim that "poets are the unacknowledged legislators of the world". The essay was written in response to his friend Thomas Love Peacock's article "The Four Ages of Poetry", which had been published in 1820. Shelley wrote to the publishers Charles and James Ollier (who were also his own publishers):

I am enchanted with your Literary Miscellany, although the last article has excited my polemical faculties so violently that the moment I get rid of my ophthalmia, I mean to set about an answer to it.... It is very clever, but I think, very false.

To Peacock, Shelley wrote:

Your anathemas against poetry itself excited me to a sacred rage. . . . I had the greatest possible desire to break a lance with you ... in honour of my mistress Urania.

A Few Passages from the text

Who are the Poets?

But poets, or those who imagine and express this indestructible order, are not only the authors of language and of music, of the dance, and architecture, and statuary, and painting; they are the institutors of laws, and the founders of civil society, and the inventors of the arts of life, and the teachers, who draw into a certain propinquity with the beautiful and the true, that partial apprehension of the agencies of the invisible world which is called religion. Hence all original religions are allegorical, or susceptible of allegory, and, like Janus, have a double face of false and true. Poets, according to the circumstances of the age and nation in which they appeared, were called, in the earlier epochs of the world, legislators, or prophets: a poet essentially comprises and unit es both these characters. For he not only beholds intensely the present as it is, and discovers those laws according to which present things ought to be ordered, but he beholds the future in the present, and his thoughts are the germs of the flower and the fruit of latest time. Not that I assert poets to be prophets in the gross sense of the word, or that they can foretell the form as surely as they foreknow the spirit of events: such is the pretence of superstition, which would make poetry an attribute of prophecy, rather than prophecy an attribute of poetry. A poet participates in the eternal, the infinite, and the one; as far as relates to his conceptions, time and place and number are not. The grammatical forms which express the moods of time, and the difference of persons, and the distinction of place, are convertible with respect to the highest poetry without injuring it as poetry; and the choruses of Aeschylus, and the book of Job, and Dante's Paradise, would afford, more than any other writings, examples of this fact, if the limits of this essay did not forbid citation. The creations of sculpture, painting, and music, are illustrations still more decisive.

 

What is Poetry?

A poem is the very image of life expressed in its eternal truth. There is this difference between a story and a poem, that a story is a catalogue of detached facts, which have no other connexion than time, place, circumstance, cause and effect; the other is the creation of actions according to the unchangeable forms of human nature, as existing in the mind of the Creator, which is itself the image of all other minds. The one is partial, and applies only to a definite period of time, and a certain combination of events which can never again recur; the other is universal, and contains within itself the germ of a relation to whatever motives or actions have place in the possible varieties of human nature. Time, which destroys the beauty and the use of the story of particular facts, stripped of the poetry which should invest them, augments that of poetry, and for ever develops new and wonderful applications of the eternal truth which it contains. Hence epitomes have been called the moths of just history; they eat out the poetry of it. A story of particular facts is as a mirror which obscures and distorts that which should be beautiful: poetry is a mirror which makes beautiful that which is distorted.

Poetry and Utility

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 superstition, 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 labour, 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.

The Use of Poetry

Poetry is indeed something divine. It is at once the centre and circumference of knowledge; it is that which comprehends all science, and that to which all science must be referred. It is at the same time the root and blossom of all other systems of thought; it is that from which all spring, and that which adorns all; and that which, if blighted, denies the fruit and the seed, and withholds from the barren world the nourishment and the succession of the scions of the tree of life. It is the perfect and consummate surface and bloom of all things; it is as the odour and the colour of the rose to the texture of the elements which compose it, as the form and splendour of unfaded beauty to the secrets of anatomy and corruption. What were virtue, love, patriotism, friendship—what were the scenery of this beautiful universe which we inhabit; what were our consolations on this side of the grave—and what were our aspirations beyond it, if poetry did not ascend to bring light and fire from those eternal regions where the owl-winged faculty of calculation dare not ever soar? Poetry is not like reasoning, a power to be exerted according to the determination of the will. A man cannot say, 'I will compose poetry.' The greatest poet even cannot say it; for the mind in creation is as a fading coal, which some invisible influence, like an inconstant wind, awakens to transitory brightness; this power arises from within, like the colour of a flower which fades and changes as it is developed, and the conscious portions of our natures are unprophetic either of its approach or its departure. Could this influence be durable in its original purity and force, it is impossible to predict the greatness of the results; but when composition begins, inspiration is already on the decline, and the most glorious poetry that has ever been communicated to the world is probably a feeble shadow of the original conceptions of the poet. I appeal to the greatest poets of the present day, whether it is not an error to assert that the finest passages of poetry are produced by labour and study. The toil and the delay recommended by critics, can be justly interpreted to mean no more than a careful observation of the inspired moments, and an artificial connexion of the spaces between their suggestions by the intertexture of conventional expressions; a necessity only imposed by the limitedness of the poetical faculty itself; for Milton conceived the Paradise Lost as a whole before he executed it in portions; We have his own authority also for the muse having 'dictated' to him the 'unpremeditated song'. And let this be an answer to those who would allege the fifty-six various readings of the first line of the Orlando Furioso. Compositions so produced are to poetry what mosaic is to painting. This instinct and intuition of the poetical faculty, is still more observable in the plastic and pictorial arts; a great statue or picture grows under the power of the artist as a child in the mother's womb; and the very mind which directs the hands in formation is incapable of accounting to itself for the origin, the gradations, or the media of the process.

Poetry is the record of the best and happiest moments of the happiest and best minds. We are aware of evanescent visitations of thought and feeling sometimes associated with place or person, sometimes regarding our own mind alone, and always arising unforeseen and departing unbidden, but elevating and delightful beyond all expression; so that even in the desire and regret they leave, there cannot but be pleasure, participating as it does in the nature of its object. It is as it were the interpenetration of a diviner nature through our own; but its footsteps are like those of a wind over the sea, which the coming calm erases, and whose traces remain only, as on the wrinkled sand which paves it. These and corresponding conditions of being are experienced principally by those of the most delicate sensibility and the most enlarged imagination; and the state of mind produced by them is at war with every base desire. The enthusiasm of virtue, love, patriotism, and friendship, is essentially linked with such emotions; and whilst they last, self appears as what it is, an atom to a universe. Poets are not only subject to these experiences as spirits of the most refined organization, but they can colour all that they combine with the evanescent hues of this ethereal world; a word, a trait in the representation of a scene or a passion, will touch the enchanted chord, and reanimate, in those who have ever experienced these emotions, the sleeping, the cold, the buried image of the past. Poetry thus makes immortal all that is best and most beautiful in the world; it arrests the vanishing apparitions which haunt the interlunations of life, and veiling them, or in language or in form, sends them forth among mankind, bearing sweet news of kindred joy to those with whom their sisters abide—abide, because there is no portal of expression from the caverns of the spirit which they inhabit into the universe of things. Poetry redeems from decay the visitations of the divinity in man.

Poetry turns all things to loveliness; it exalts the beauty of that which is most beautiful, and it adds beauty to that which is most deformed; it marries exultation and horror, grief and pleasure, eternity and change; it subdues to union under its light yoke, all irreconcilable things. It transmutes all that it touches, and every form moving within the radiance of its presence is changed by wondrous sympathy to an incarnation of the spirit which it breathes: its secret alchemy turns to potable gold the poisonous waters which flow from death through life; it strips the veil of familiarity from the world, and lays bare the naked and sleeping beauty, which is the spirit of its forms
