In just this way, Shelley believed in perfectibility. In his latest poems—in Hellas, in Adonais—he was perhaps a little inclined to remove the scene of perfectibility to a metaphysical region, as the Christian church soon removed it to the other world. Indeed, an earth really made perfect is hardly distinguishable from a posthumous heaven: so profoundly must everything in it be changed, and so angel-like must every one in it become. Shelley's earthly paradise, as described in Prometheus and in Epipsychidion, is too festival-like too much of a mere culmination, not to be fugitive: it cries aloud to be translated into a changeless and metaphysical heaven, which to Shelley's mind could be nothing but the realm of Platonic ideas, where "life, like a dome of many-coloured glass," no longer "stains the white radiance of eternity." But the age had been an age of revolution and, in spite of disappointments, retained its faith in revolution; and the young Shelley was not satisfied with a paradise removed to the intangible realms of poetry or of religion; he hoped, like the old Hebrews, for a paradise on earth. His notion was that eloquence could change the heart of man, and that love, kindled there by the force of reason and of example, would transform society. He believed, Mrs. Shelley tells us, "that mankind had only to will that there should be no evil, and there would be none." And she adds: "That man could be so perfectionised as to be able to expel evil from his own nature, and from the greater part of creation, was the cardinal point of his system." This cosmic extension of the conversion of men reminds one of the cosmic extension of the Fall conceived by St. Augustine; and in the Prometheus Shelley has allowed his fancy, half in symbol, half in glorious physical hyperbole, to carry the warm contagion of love into the very bowels of the earth, and even the moon, by reflection, to catch the light of love, and be alive again.

Shelley, we may safely say, did not understand the real constitution of nature. It was hidden from him by a cloud, all woven of shifting rainbows and bright tears. Only his emotional haste made it possible for him to entertain such, opinions as he did entertain; or rather, it was inevitable that the mechanism of nature, as it is in its depths, should remain in his pictures only the shadowiest of backgrounds. His poetry is accordingly a part of the poetry of illusion; the poetry of truth, if we have the courage to hope for such a thing, is reserved for far different and yet unborn poets. But it is only fair to Shelley to remember that the moral being of mankind is as yet in its childhood; all poets play with images not understood; they touch on emotions sharply, at random, as in a dream; they suffer each successive vision, each poignant sentiment, to evaporate into nothing, or to leave behind only a heart vaguely softened and fatigued, a gentle languor, or a tearful hope. Every modern school of poets, once out of fashion, proves itself to have been sadly romantic and sentimental. None has done better than to spangle a confused sensuous pageant with some sparks of truth, or to give it some symbolic relation to moral experience. And this Shelley has done as well as anybody: all other poets also have been poets of illusion. The distinction of Shelley is that his illusions are so wonderfully fine, subtle, and palpitating; that they betray passions and mental habits so singularly generous and pure. And why? Because he did not believe in the necessity of what is vulgar, and did not pay that demoralising respect to it, under the title of fact or of custom, which it exacts from most of us. The past seemed to him no valid precedent, the present no final instance. As he believed in the imminence of an overturn that should make all things new, he was not checked by any divided allegiance, by any sense that he was straying into the vapid or fanciful, when he created what he justly calls "Beautiful idealisms of moral excellence."

That is what his poems are fundamentally—the Skylark, and the Witch of the Atlas, and the Sensitive Plant no less than the grander pieces. He infused into his gossamer world the strength of his heroic conscience. He felt that what his imagination pictured was a true symbol of what human experience should and might pass into. Otherwise he would have been aware of playing with idle images; his poetry would have been mere millinery and his politics mere business; he would have been a worldling in art and in morals. The clear fire, the sustained breath, the fervent accent of his poetry are due to his faith in his philosophy. As Mrs. Shelley expressed it, he "had no care for any of his poems that did not emanate from the depths of his mind, and develop some high and abstruse truth." Had his poetry not dealt with what was supreme in his own eyes, and dearest to his heart, it could never have been the exquisite and entrancing poetry that it is. It would not have had an adequate subject-matter, as, in spite of Matthew Arnold, I think it had; for nothing can be empty that contains such a soul. An angel cannot be ineffectual if the standard of efficiency is moral; he is what all other things bring about, when they are effectual. And a void that is alive with the beating of luminous wings, and of a luminous heart, is quite sufficiently peopled. Shelley's mind was angelic not merely in its purity and fervour, but also in its moral authority, in its prophetic strain. What was conscience in his generation was life in him.

The mind of man is not merely a sensorium. His intelligence is not merely an instrument for adaptation. There is a germ within, a nucleus of force and organisation, which can be unfolded, under favourable circumstances, into a perfection inwardly determined. Man's constitution is a fountain from which to draw an infinity of gushing music, not representing anything external, yet not unmeaning on that account, since it represents the capacities and passions latent in him from the beginning. These potentialities, however, are no oracles of truth. Being innate they are arbitrary; being a priori they are subjective; but they are good principles for fiction, for poetry, for morals, for religion. They are principles for the true expression of man, but not for the true description of the universe. When they are taken for the latter, fiction becomes deception, poetry illusion, morals fanaticism, and religion bad science. The orgy of delusion into which we are then plunged comes from supposing the a priori to be capable of controlling the actual, and the innate to be a standard for the true. That rich and definite endowment which might have made the distinction of the poet, then makes the narrowness of the philosopher. So Shelley, with a sort of tyranny of which he does not suspect the possible cruelty, would impose his ideal of love and equality upon all creatures; he would make enthusiasts of clowns and doves of vultures. In him, as in many people, too intense a need of loving excludes the capacity for intelligent sympathy. His feeling cannot accommodate itself to the inequalities of human nature: his good will is a geyser, and will not consent to grow cool, and to water the flat and vulgar reaches of life. Shelley is blind to the excellences of what he despises, as he is blind to the impossibility of realising what he wants. His sympathies are narrow as his politics are visionary, so that there is a certain moral incompetence in his moral intensity. Yet his abstraction from half of life, or from nine-tenths of it, was perhaps necessary if silence and space were to be won in his mind for its own upwelling, ecstatic harmonies. The world we have always with us, but such spirits we have not always. And the spirit has fire enough within to make a second stellar universe.

An instance of Shelley's moral incompetence in moral intensity is to be found in his view of selfishness and evil. From the point of view of pure spirit, selfishness is quite absurd. As a contemporary of ours has put it: "It is so evident that it is better to secure a greater good for A than a lesser good for B that it is hard to find any still more evident principle by which to prove this. And if A happens to be some one else, and B to be myself, that cannot affect the question." It is very foolish not to love your neighbour as yourself, since his good is no less good than yours. Convince people of this—and who can resist such perfect logic?—and presto all property in things has disappeared, all jealousy in love, and all rivalry in honour. How happy and secure every one will suddenly be, and how much richer than in our mean, blind, competitive society! The single word love—and we have just seen that love is a logical necessity—offers an easy and final solution to all moral and political problems. Shelley cannot imagine why this solution is not accepted, and why logic does not produce love. He can only wonder and grieve that it does not; and since selfishness and ill-will seem to him quite gratuitous, his ire is aroused; he thinks them unnatural and monstrous. He could not in the least understand evil, even when he did it himself; all villainy seemed to him wanton, all lust frigid, all hatred insane. All was an abomination alike that was not the lovely spirit of love.

Now this is a very unintelligent view of evil; and if Shelley had had time to read Spinoza—an author with whom he would have found himself largely in sympathy—he might have learned that nothing is evil in itself, and that what is evil in things is not due to any accident in creation, nor to groundless malice in man. Evil is an inevitable aspect which things put on when they are struggling to preserve themselves in the same habitat, in which there is not room or matter enough for them to prosper equally side by side. Under these circumstances the partial success of any creature—say, the cancer-microbe—is an evil from the point of view of those other creatures—say, men—to whom that success is a defeat. Shelley sometimes half perceived this inevitable tragedy. So he says of the fair lady in the Sensitive Plant:

"All killing insects and gnawing worms,
And things of obscene and unlovely forms,
She bore in a basket of Indian woof,
Into the rough woods far aloof—
In a basket of grasses and wild flowers full,
The freshest her gentle hands could pull
For the poor banished insects, whose intent,
Although they did ill, was innocent."

Now it is all very well to ask cancer-microbes to be reasonable, and go feed on oak-leaves, if the oak-leaves do not object; oak-leaves might be poison for them, and in any case cancer-microbes cannot listen to reason; they must go on propagating where they are, unless they are quickly and utterly exterminated. And fundamentally men are subject to the same fatality exactly; they cannot listen to reason unless they are reasonable; and it is unreasonable to expect that, being animals, they should be reasonable exclusively. Imagination is indeed at work in them, and makes them capable of sacrificing themselves for any idea that appeals to them, for their children, perhaps, or for their religion. But they are not more capable of sacrificing themselves to what does not interest them than the cancer-microbes are of sacrificing themselves to men.

When Shelley marvels at the perversity of the world, he shows his ignorance of the world. The illusion he suffers from is constitutional, and such as larks and sensitive plants are possibly subject to in their way: what he is marvelling at is really that anything should exist at all not a creature of his own moral disposition. Consequently the more he misunderstands the world and bids it change its nature, the more he expresses his own nature: so that all is not vanity in his illusion, nor night in his blindness. The poet sees most clearly what his ideal is; he suffers no illusion in the expression of his own soul. His political utopias, his belief in the power of love, and his cryingly subjective and inconstant way of judging people are one side of the picture; the other is his lyrical power, wealth, and ecstasy. If he had understood universal nature, he would not have so glorified in his own. And his own nature was worth glorifying; it was, I think, the purest, tenderest, richest, most rational nature ever poured forth in verse. I have not read in any language such a full expression of the unadulterated instincts of the mind. The world of Shelley is that which the vital monad within many of us—I will not say within all, for who shall set bounds to the variations of human nature?—the world which the vital monad within many of us, I say, would gladly live in if it could have its way.

Matthew Arnold said that Shelley was not quite sane; and certainly he was not quite sane, if we place sanity in justness of external perception, adaptation to matter, and docility to the facts; but his lack of sanity was not due to any internal corruption; it was not even an internal eccentricity. He was like a child, like a Platonic soul just fallen from the Empyrean; and the child may be dazed, credulous, and fanciful; but he is not mad. On the contrary, his earnest playfulness, the constant distraction of his attention from observation to daydreams, is the sign of an inward order and fecundity appropriate to his age. If children did not see visions, good men would have nothing to work for. It is the soul of observant persons, like Matthew Arnold, that is apt not to be quite sane and whole inwardly, but somewhat warped by familiarity with the perversities of real things, and forced to misrepresent its true ideal, like a tree bent by too prevalent a wind. Half the fertility of such a soul is lost, and the other half is denaturalised. No doubt, in its sturdy deformity, the practical mind is an instructive and not unpleasing object, an excellent, if somewhat pathetic, expression of the climate in which it is condemned to grow, and of its dogged clinging to an ingrate soil; but it is a wretched expression of its innate possibilities. Shelley, on the contrary, is like a palm-tree in the desert or a star in the sky; he is perfect in the midst of the void. His obtuseness to things dynamic—to the material order—leaves his whole mind free to develop things æsthetic after their own kind; his abstraction permits purity, his playfulness makes room for creative freedom, his ethereal quality is only humanity having its way.
