A Defence of Poetry by Percy Bysshe Shelley
"A Defence of Poetry" by Percy Bysshe Shelley is a philosophical essay that articulates the essential role and significance of poetry in society. Published posthumously in 1840, the work emerges as a response to Thomas Love Peacock's critique of contemporary poetry, which suggested that poetry belonged to primitive societies and dwindled in importance with civilization. In contrast, Shelley posits that poetry is a vital human faculty present in all individuals, asserting that poets serve as "unacknowledged legislators" who reveal truths about the world and inspire societal betterment. Unlike previous defenses of poetry, Shelley emphasizes imagination over craftsmanship, arguing that true poets possess a unique vision that transcends time and communicates universal truths. He contends that poetry should not merely be seen as a source of pleasure but as a profound expression of harmony and knowledge that challenges the rational limitations of the age. Shelley's essay ultimately defends poetry as a divine and transformative force, capable of capturing the best moments of humanity and contributing to the evolution of civil society. The work reflects Shelley's deep belief in the power of art and its integral role in fostering a more enlightened and compassionate world.

A Defence of Poetry by Percy Bysshe Shelley
First published: 1840
Type of work: Essay
The Work:
Readers familiar with other great “defenses” of poetry may find Percy Bysshe Shelley’s A Defence of Poetry unusual, even confusing. There is little practical analysis of the elements of good literary work. There is no methodical history of poetry, as one reads in Sir Philip Sidney’s Defence of Poesie (1595). There are no pronouncements about rules of composition. Instead, Shelley offers a philosophical analysis of the role of the poet as a special kind of person, one who can see the essential harmonies of the world beneath the discordant images people find in their everyday lives. Whereas Aristotle, Sidney, or John Dryden see the poet as a superb craftsman capable of delighting readers through the masterful blending of form and content, Shelley assigns the poet a higher calling: the revelation of truth about life and the promotion of universal betterment.

These high claims are justified by Shelley’s insistence that the production of poetry is not simply a craft. Rather, the true poet is a visionary who is inspired to create art as a means of revealing something about the nature of the world. The poem itself is merely an attempt to reproduce that vision. Such claims have been misinterpreted, and Shelley has been accused of promoting automatic writing or of devaluing the importance of craftsmanship. On the contrary: Shelley sees the imagination as a shaping power that gives form to the poet’s vision, and only those who master form can hope to convey their vision to readers. Similarly, claims that Shelley is a promoter of emotional poetry are wrongheaded; he is insistent that the practice of poetry involves the intellect as well as the heart. He believes that great poets have a special gift that allows them to use the materials of their own time (the forms and subjects that might appeal to their contemporary readers), but transcend the limits of time and place to speak to people of all ages.
In this essay Shelley is defending poetry—“my mistress, Urania”—against the attack by Thomas Love Peacock in “The Four Ages of Poetry,” published in the first and only issue of the Literary Miscellany in 1820. The polemical exchange came to nothing, for A Defence of Poetry remained unpublished until 1840. In his essay, Peacock had elaborated the familiar figure of the Golden and Silver Ages of classical poetry into four (Iron, Gold, Silver, and Brass), skipped over “the dark ages,” and repeated the succession in English poetry. Peacock’s point was that poetry never amounts to much in civilized society; Shelley’s defense is that poetry is essential. Their views were antithetical and neither made contact with the other: Peacock’s attack is a boisterous satire, Shelley’s defense is an elevated prose poem.
Nevertheless, Peacock’s article is still a necessary preface to Shelley’s arguments, not because one prompted the other or because Shelley adopted Peacock’s historical method in the middle section of his essay, but because, as a pair, they show the opposing preferences of the older public for eighteenth century wit and of the younger for enthusiasm. Peacock’s “The Four Ages of Poetry” has also the merit of being amusing; Shelley is never amusing. Peacock’s argument is that poetry belongs properly to primitive societies, that as they become civilized they become rational and nonpoetical; hence it was not until the late seventeenth century that England equaled, in the work of William Shakespeare and John Milton, the Golden Age of Homeric Greece. Early nineteenth century England seemed, to him, to have reached the Age of Brass in poetry but a kind of Golden Age in science; therefore, poetry should be left to the primitive societies where it belongs. Peacock is most amusing in his picture of the first Age of Iron, in which the bard of the tribal chief “is always ready to celebrate the strength of his arm, being first duly inspired by that of his liquor.” Apart from Homer, Peacock respects no poet, not even Shakespeare, who mixed his unities and thought nothing of “deposing a Roman Emperor by an Italian Count, and sending him off in the disguise of a French pilgrim to be shot with a blunderbuss by an English archer.” Peacock’s jest turns sour as he tires of his figure, and his strictures on contemporary poetry become a diatribe of which the gist is that “a poet of our times is a semibarbarian in a civilized community.” Shelley, to whom Peacock sent a copy of his essay, was stirred to write his only prose statement on his craft. In it he came to the memorable conclusion that “Poets are the unacknowledged legislators of the world.”
A Defence of Poetry falls into three parts. First, Shelley presents an argument that all people are poets in some degree, for poetry is an innate human faculty; hence, it is seen in all societies at all times and to eternity. In the second part, he attempts the historical proof, which he abandons in the third to make a subjective and poetic affirmation of the perpetual presence and ennobling virtue of poetry. In presenting his beliefs, Shelley uses the ideas that inspire his poems and attempts to codify them from the base Peacock had given him. Peacock could begin at once with his first age, however; Shelley found it necessary to begin by defining his notion of poetry. Two major ideas run through this first section and are reflected in the rest of the essay: the Platonic idea of mimesis, in which the imagination responds to the eternal verities it glimpses behind the material form, and the eighteenth century idea of the “sympathetic imagination” that, of its own initiative, extends itself and assumes an empathy with external objects and beings. The first idea leads Shelley to assert the superiority of the poet as the most active in using the glimpses of truth and conveying them to lesser beings for their uplifting; for this reason, the poet is the most powerful influence on humankind, a “legislator.” The second idea gives the poet an insight into the ills of humankind which, once understood, can be corrected; here is the second meaning of “legislator.”
The first part presented is in two sections, dealing first with the mimetic, then with the expressive powers of poetry, which powers are part of the definition of poetry; the other two parts of the definition are contained in four paragraphs on the form of poetry, especially on its use of language, the medium that makes it superior to other art media and which is called “measured” in contradistinction to “unmeasured” language or prose. The whole essay is prefaced by four paragraphs that define poetry in the largest or organic sense, not by its mechanics. These paragraphs go to the heart of the difference between Peacock and Shelley.
Shelley begins with a distinction between reason and imagination, leaving to the former the work of numbering, analyzing, and relating objects; the imagination perceives the similitude of objects in their innate values, not in their appearance, and synthesizes these values, presumably, into a valid and Platonic One or Truth. The synthetic principle of the imagination is poetry; the individual is compared to “an Aeolian lyre,” subject to impressions external and internal but possessing an inner principle (poetry) that produces not simply melody but harmony. Poetry is thus both the name of a form of language (measured) and of the power of producing it and benefiting from the poem. Shelley asserts that poets are “the institutors of laws, and the founders of civil society” because they discover the laws of harmony and become “legislators” by giving these laws the form of a poem. The poetic product or poem may be an act of mimesis, but the act proceeds from the poetic faculty highly developed in the poet and contained in all people: “A poem is the very image of life expressed in its eternal truth.”
The argument in the second section of the first part, devoted to the effects of poetry on society, has been anticipated in the foregoing analysis. A Defence of Poetry, as an “apologia,” could well end at that point, but Shelley wanted to convince Peacock that his theory has external evidence. This he offers in the second part of the essay.
The historical method had already been touched on in Shelley’s example of the propensity of the savage or child to imitate the impressions it receives, as a lyre produces melody only. Shelley’s reading of history is as willful as Peacock’s in his assertion that the morality of an age corresponds to the goodness or badness of its poetry; he adduces Greek classical drama as an evidence of a healthy society and Hellenic bucolic poetry as a sign of decay when the poets ceased to be the acknowledged legislators of the Alexandrian Hellenes. In order to cope with the same progression of health and decay in the literature of Rome, which would seem to prove Peacock’s scheme, Shelley shifts the whole cycle into “episodes of that cyclic poem written by time upon the memories of men.” He encounters further difficulty in coping with Christianity, for, by Shelley’s theory, Jesus must be a great poet: “The scattered fragments preserved to us by the biographers of this extraordinary person, are all instinct with the most vivid poetry.” Something went wrong in the Dark Ages, which brought “the extinction of the poetic principle . . . from causes too intricate to be here discussed.” Shelley feels safer with Dante Alighieri and John Milton: “But let us not be betrayed from a defence into a critical history of poetry.”
After abandoning the historical method which, had he followed Peacock step by step, would have brought him up to his contemporaries, Shelley returns to his defence by attacking “the promoters of utility” and, by implication, Peacock. To the utilitarian objection that poetry simply produces pleasure and that pleasure is profitless, Shelley asserts that the pleasure of poetry lies not in its superficial melody but in its innate harmony, alone capable of checking “the calculating faculty” that has already produced “more scientific and economical knowledge than can be accommodated to the just distribution of the produce which it multiplies.” Shelley follows this with a paragraph that summarizes the duality of the “poetic faculty”; by synthesis it “creates new materials of knowledge and power and pleasure,” and by its expressive powers it reproduces those materials “according to a certain rhythm and order which may be called the beautiful and the good.”
Shelley’s peroration, his personal and poetic justification for poetry, opens with three paragraphs beginning: “Poetry is indeed something divine”; “Poetry is the record of the best and happiest moments of the happiest and best minds”; “Poetry turns all things to loveliness.” This is the moving genius of Adonais. Searching for the best proof to defend poetry from the rationalizations of Peacock, Shelley follows the prompting of his own “poetic principle” in concluding A Defence of Poetry with a sustained lyric in prose that Peacock could never match. The power of this essay is still inspiring. It constitutes Shelley’s best claim outside his verse to be a “legislator” to the world.
