In Shelley’s poetry, the figure of the poet (and, to some extent, the figure of Shelley himself) is not simply a talented entertainer or even a perceptive moralist but a grand, tragic, prophetic hero. The poet has a deep, mystic appreciation for nature, as in the poem “To Wordsworth” (1816), and this intense connection with the natural world gives him access to profound cosmic truths, as in “Alastor; or, The Spirit of Solitude” (1816). He has the power—and the duty—to translate these truths, through the use of his imagination, into poetry, but only a kind of poetry that the public can understand. Thus, his poetry becomes a kind of prophecy, and through his words, a poet has the ability to change the world for the better and to bring about political, social, and spiritual change. Shelley’s poet is a near-divine savior, comparable to Prometheus, who stole divine fire and gave it to humans in Greek mythology, and to Christ. Like Prometheus and Christ, figures of the poets in Shelley’s work are often doomed to suffer: because their visionary power isolates them from other men, because they are misunderstood by critics, because they are persecuted by a tyrannical government, or because they are suffocated by conventional religion and middle-class values. In the end, however, the poet triumphs because his art is immortal, outlasting the tyranny of government, religion, and society and living on to inspire new generations.
Like many of the romantic poets, especially William Wordsworth, Shelley demonstrates a great reverence for the beauty of nature, and he feels closely connected to nature’s power. In his early poetry, Shelley shares the romantic interest in pantheism—the belief that God, or a divine, unifying spirit, runs through everything in the universe. He refers to this unifying natural force in many poems, describing it as the “spirit of beauty” in “Hymn to Intellectual Beauty” and identifying it with Mont Blanc and the Arve River in “Mont Blanc.” This force is the cause of all human joy, faith, goodness, and pleasure, and it is also the source of poetic inspiration and divine truth. Shelley asserts several times that this force can influence people to change the world for the better. However, Shelley simultaneously recognizes that nature’s power is not wholly positive. Nature destroys as often as it inspires or creates, and it destroys cruelly and indiscriminately. For this reason, Shelley’s delight in nature is mitigated by an awareness of its dark side.
Shelley uses nature as his primary source of poetic inspiration. In such poems as “The Mask of Anarchy Written on the Occasion of the Massacre at Manchester” (1819) and “Ode to the West Wind,” Shelley suggests that the natural world holds a sublime power over his imagination. This power seems to come from a stranger, more mystical place than simply his appreciation for nature’s beauty or grandeur. At the same time, although nature has creative power over Shelley because it provides inspiration, he feels that his imagination has creative power over nature. It is the imagination—or our ability to form sensory perceptions—that allows us to describe nature in different, original ways, which help to shape how nature appears and, therefore, how it exists. Thus, the power of the human mind becomes equal to the power of nature, and the experience of beauty in the natural world becomes a kind of collaboration between the perceiver and the perceived. Because Shelley cannot be sure that the sublime powers he senses in nature are only the result of his gifted imagination, he finds it difficult to attribute nature’s power to God: the human role in shaping nature damages Shelley’s ability to believe that nature’s beauty comes solely from a divine source.
