Yet in the womb of the Revolution itself, and in the storm and terror of that wild time, tendencies were hidden away that the artistic Renaissance bent to her own service when the time came - a scientific tendency first, which has borne in our own day a brood of somewhat noisy Titans, yet in the sphere of poetry has not been unproductive of good. I do not mean merely in its adding to enthusiasm that intellectual basis which in its strength, or that more obvious influence about which Wordsworth was thinking when he said very nobly that poetry was merely the impassioned expression in the face of science, and that when science would put on a form of flesh and blood the poet would lend his divine spirit to aid the transfiguration. Nor do I dwell much on the great cosmical emotion and deep pantheism of science to which Shelley has given its first and Swinburne its latest glory of song, but rather on its influence on the artistic spirit in preserving that close observation and the sense of limitation as well as of clearness of vision which are the characteristics of the real artist.
The great and golden rule of art as well as of life, wrote William Blake, is that the more distinct, sharp and defined the boundary line, the more perfect is the work of art; and the less keen and sharp the greater is the evidence of weak imitation, plagiarism and bungling. 'Great inventors in all ages knew this - Michael Angelo and Albert Durer are known by this and by this alone'; and another time he wrote, with all the simple directness of nineteenth-century prose, 'to generalise is to be an idiot.'
And this love of definite conception, this clearness of vision, this artistic sense of limit, is the characteristic of all great work and poetry; of the vision of Homer as of the vision of Dante, of Keats and William Morris as of Chaucer and Theocritus. It lies at the base of all noble, realistic and romantic work as opposed to the colourless and empty abstractions of our own eighteenth-century poets and of the classical dramatists of France, or of the vague spiritualities of the German sentimental school: opposed, too, to that spirit of transcendentalism which also was root and flower itself of the great Revolution, underlying the impassioned contemplation of Wordsworth and giving wings and fire to the eagle-like flight of Shelley, and which in the sphere of philosophy, though displaced by the materialism and positiveness of our day, bequeathed two great schools of thought, the school of Newman to Oxford, the school of Emerson to America. Yet is this spirit of transcendentalism alien to the spirit of art. For the artist can accept no sphere of life in exchange for life itself. For him there is no escape from the bondage of the earth: there is not even the desire of escape.
He is indeed the only true realist: symbolism, which is the essence of the transcendental spirit, is alien to him. The metaphysical mind of Asia will create for itself the monstrous, many-breasted idol of Ephesus, but to the Greek, pure artist, that work is most instinct with spiritual life which conforms most clearly to the perfect facts of physical life.
'The storm of revolution,' as Andre Chenier said, 'blows out the torch of poetry.' It is not for some little time that the real influence of such a wild cataclysm of things is felt: at first the desire for equality seems to have produced personalities of more giant and Titan stature than the world had ever known before. Men heard the lyre of Byron and the legions of Napoleon; it was a period of measureless passions and of measureless despair;ambition, discontent, were the chords of life and art; the age was an age of revolt: a phase through which the human spirit must pass, but one in which it cannot rest. For the aim of culture is not rebellion but peace, the valley perilous where ignorant armies clash by night being no dwelling-place meet for her to whom the gods have assigned the fresh uplands and sunny heights and clear, untroubled air.
And soon that desire for perfection, which lay at the base of the Revolution, found in a young English poet its most complete and flawless realisation.
Phidias and the achievements of Greek art are foreshadowed in Homer: Dante prefigures for us the passion and colour and intensity of Italian painting: the modern love of landscape dates from Rousseau, and it is in Keats that one discerns the beginning of the artistic renaissance of England.
Byron was a rebel and Shelley a dreamer; but in the calmness and clearness of his vision, his perfect self-control, his unerring sense of beauty and his recognition of a separate realm for the imagination, Keats was the pure and serene artist, the forerunner of the pre-Raphaelite school, and so of the great romantic movement of which I am to speak.
Blake had indeed, before him, claimed for art a lofty, spiritual mission, and had striven to raise design to the ideal level of poetry and music, but the remoteness of his vision both in painting and poetry and the incompleteness of his technical powers had been adverse to any real influence. It is in Keats that the artistic spirit of this century first found its absolute incarnation.
And these pre-Raphaelites, what were they? If you ask nine-tenths of the British public what is the meaning of the word aesthetics, they will tell you it is the French for affectation or the German for a dado; and if you inquire about the pre-Raphaelites you will hear something about an eccentric lot of young men to whom a sort of divine crookedness and holy awkwardness in drawing were the chief objects of art. To know nothing about their great men is one of the necessary elements of English education.
