And so it is in poetry also:  all this love of curious French metres like the Ballade, the Villanelle, the Rondel; all this increased value laid on elaborate alliterations, and on curious words and refrains, such as you will find in Dante Rossetti and Swinburne, is merely the attempt to perfect flute and viol and trumpet through which the spirit of the age and the lips of the poet may blow the music of their many messages.

And so it has been with this romantic movement of ours:  it is a reaction against the empty conventional workmanship, the lax execution of previous poetry and painting, showing itself in the work of such men as Rossetti and Burne-Jones by a far greater splendour of colour, a far more intricate wonder of design than English imaginative art has shown before.  In Rossetti’s poetry and the poetry of Morris, Swinburne and Tennyson a perfect precision and choice of language, a style flawless and fearless, a seeking for all sweet and precious melodies and a sustaining consciousness of the musical value of each word are opposed to that value which is merely intellectual.  In this respect they are one with the romantic movement of France of which not the least characteristic note was struck by Theophile Gautier’s advice to the young poet to read his dictionary every day, as being the only book worth a poet’s reading.

While, then, the material of workmanship is being thus elaborated and discovered to have in itself incommunicable and eternal qualities of its own, qualities entirely satisfying to the poetic sense and not needing for their aesthetic effect any lofty intellectual vision, any deep criticism of life or even any passionate human emotion at all, the spirit and the method of the poet’s working—­what people call his inspiration—­have not escaped the controlling influence of the artistic spirit.  Not that the imagination has lost its wings, but we have accustomed ourselves to count their innumerable pulsations, to estimate their limitless strength, to govern their ungovernable freedom.

To the Greeks this problem of the conditions of poetic production, and the places occupied by either spontaneity or self-consciousness in any artistic work, had a peculiar fascination.  We find it in the mysticism of Plato and in the rationalism of Aristotle.  We find it later in the Italian Renaissance agitating the minds of such men as Leonardo da Vinci.  Schiller tried to adjust the balance between form and feeling, and Goethe to estimate the position of self-consciousness in art.  Wordsworth’s definition of poetry as ‘emotion remembered in tranquillity’ may be taken as an analysis of one of the stages through which all imaginative work has to pass; and in Keats’s longing to be ’able to compose without this fever’ (I quote from one of his letters), his desire to substitute for poetic ardour ‘a more thoughtful and quiet power,’ we may discern the most important moment in the evolution of that artistic life.  The question made an early and strange appearance in your literature too; and I need not remind you how deeply the young poets of the French romantic movement were excited and stirred by Edgar Allan Poe’s analysis of the workings of his own imagination in the creating of that supreme imaginative work which we know by the name of The Raven.
