Notes to the Complete Poetical Works of Percy Bysshe Shelley — Background and Themes

They were written as his mind prompted: listening to the carolling of the bird, aloft in the azure sky of Italy; or marking the cloud as it sped across the heavens, while he floated in his boat on the Thames.

No poet was ever warmed by a more genuine and unforced inspiration. His extreme sensibility gave the intensity of passion to his intellectual pursuits; and rendered his mind keenly alive to every perception of outward objects, as well as to his internal sensations. Such a gift is, among the sad vicissitudes of human life, the disappointments we meet, and the galling sense of our own mistakes and errors, fraught with pain; to escape from such, he delivered up his soul to poetry, and felt happy when he sheltered himself, from the influence of human sympathies, in the wildest regions of fancy. His imagination has been termed too brilliant, his thoughts too subtle. He loved to idealize reality; and this is a taste shared by few. We are willing to have our passing whims exalted into passions, for this gratifies our vanity; but few of us understand or sympathize with the endeavour to ally the love of abstract beauty, and adoration of abstract good, the to agathon kai to kalon of the Socratic philosophers, with our sympathies with our kind. In this, Shelley resembled Plato; both taking more delight in the abstract and the ideal than in the special and tangible. This did not result from imitation; for it was not till Shelley resided in Italy that he made Plato his study. He then translated his "Symposium" and his "Ion"; and the English language boasts of no more brilliant composition than Plato's Praise of Love translated by Shelley. To return to his own poetry. The luxury of imagination, which sought nothing beyond itself (as a child burdens itself with spring flowers, thinking of no use beyond the enjoyment of gathering them), often showed itself in his verses: they will be only appreciated by minds which have resemblance to his own; and the mystic subtlety of many of his thoughts will share the same fate. The metaphysical strain that characterizes much of what he has written was, indeed, the portion of his works to which, apart from those whose scope was to awaken mankind to aspirations for what he considered the true and good, he was himself particularly attached. There is much, however, that speaks to the many. When he would consent to dismiss these huntings after the obscure (which, entwined with his nature as they were, he did with difficulty), no poet ever expressed in sweeter, more heart-reaching, or more passionate verse, the gentler or more forcible emotions of the soul.

A wise friend once wrote to Shelley: 'You are still very young, and in certain essential respects you do not yet sufficiently perceive that you are so.' It is seldom that the young know what youth is, till they have got beyond its period; and time was not given him to attain this knowledge. It must be remembered that there is the stamp of such inexperience on all he wrote; he had not completed his nine-and-twentieth year when he died. The calm of middle life did not add the seal of the virtues which adorn maturity to those generated by the vehement spirit of youth. Through life also he was a martyr to ill-health, and constant pain wound up his nerves to a pitch of susceptibility that rendered his views of life different from those of a man in the enjoyment of healthy sensations. Perfectly gentle and forbearing in manner, he suffered a good deal of internal irritability, or rather excitement, and his fortitude to bear was almost always on the stretch; and thus, during a short life, he had gone through more experience of sensation than many whose existence is protracted. 'If I die to-morrow,' he said, on the eve of his unanticipated death, 'I have lived to be older than my father.' The weight of thought and feeling burdened him heavily; you read his sufferings in his attenuated frame, while you perceived the mastery he held over them in his animated countenance and brilliant eyes.

He died, and the world showed no outward sign. But his influence over mankind, though slow in growth, is fast augmenting; and, in the ameliorations that have taken place in the political state of his country, we may trace in part the operation of his arduous struggles. His spirit gathers peace in its new state from the sense that, though late, his exertions were not made in vain, and in the progress of the liberty he so fondly loved.
