To judge of Shelley in this mode would be to leave out of account precisely those qualities in which his unique excellence is most strikingly manifested. Shelley speaks, it is true, as a prophet; but when he has reached his Pisgah, it turns out that the land of promise is by no means to be found upon this solid earth of ours, or definable by degrees of latitude and longitude, but is an unsubstantial phantasmagoria in the clouds. It is vain, too, that he declares that it is the true reality, and that what we call a reality is a dream. The transcendental world is—if we may say so—not really the world of archetypal ideas, but a fabric spun from empty phrases. The more we look at it the more clearly we recognise its origin; it is the refracted vision of Godwin's prosaic system seen through an imaginative atmosphere. But that which is really admirable is, not the vision itself, but the pathetic sentiment caused by Shelley's faint recognition of its obstinate unsubstantiality. It is with this emotion that every man must sympathise in proportion as his intellectual aspirations dominate his lower passions. Forgetting all tiresome crotchets and vapid platitudes, we may be touched, almost in proportion to our own elevation of mind, by the unsatisfied yearning for which Shelley has found such manifold and harmonious utterance. There are moods in which every sensitive and philanthropic nature groans under the heavy and the weary weight Of all this unintelligible world. Whatever our ideal may be, whatever the goal to which we hope to see mankind approximate, our spirits must often flag with a sense of our personal insignificance, and of the appalling dead weight of multiform impediments which crushes the vital energies of the world, like Etna lying upon the Titan. This despair of finding any embodiment for his own ideal, of bridging over the great gulf fixed between the actual world of sin, and sorrow, and stupidity, and the transcendental world of joy, love, and pure reason, represents the final outcome of Shelley's imperfect philosophy, and gives the theme of his most exquisite poetry. The doctrine symbolised in the 'Alastor' by the history of the poet who has seen in vision a form of perfect beauty, and dies in despair of ever finding it upon earth (he seems, poor man! to have looked for it somewhere in the neighbourhood of Afghanistan), is the clue to the history of his own intellectual life. He is happiest when he can get away from the world altogether into a vague region, having no particular relation to time or space; to the valleys haunted by the nymphs in the 'Prometheus;' or the mystic island in the 'Epipsychidion,' where all sights and sounds are as the background of a happy dream, fitting symbols of sentiments too impalpable to be fairly grasped in language: or that 'calm and blooming cove' of the lines in the Euganean hills.
