How then does the history of poetry in Europe during these sixty years stand in relation to these underlying processes? On the surface, at least, it hardly resembles growth at all. In France above all--the literary focus of Europe, and its sensitive thermometer--the movement of poetry has been, on the surface, a succession of pronounced and even fanatical schools, each born in reaction from its precursor, and succumbing to the triumph of its successor. Yet a deeper scrutiny will perceive that these warring artists were, in fact, groups of successive discoverers, who each added something to the resources and the scope of poetry, and also retained and silently adopted the discoveries of the past; while the general line of advance is in the direction marked by the two main currents I have described. Nowhere else is the succession of phases so sharp and clear as in France. But since France does reflect more sensitively than any other country the movement of the mind of Europe, and since her own mind has, more than that of any other country, radiated ideas and fashions out over the rest of Europe, these phases are in fact traceable also, with all kinds of local and national variations, in Italy and Spain, Germany and England, and I propose to take this fact as the basis of our present very summary and diagrammatic view. The three phases of the sixty years are roughly divided by the years 1880 and 1900. The first, most clearly seen in the French Parnassians, is in close, if unconscious, sympathy with the temper of science. Poetry, brought to the limit of expressive power, is used to express, with the utmost veracity, precision, and impersonal self-suppression, the beauty and the tragedy of the world. It sought Hellenic lucidity and Hellenic calm--in the example most familiar to us, the Stoic calm and 'sad lucidity' of Matthew Arnold. The second, best seen in the French Symbolists, was directly hostile to science. But they repelled its confident analysis of material reality in the name of a part of reality which it ignored or denied, an immaterial world which they mystically apprehended, which eluded direct description, frustrated rhetoric, and was only to be come at by the magical suggestion of colour, music, and symbol. It is most familiar to us in the 'Celtic' verse of Mr. Yeats and 'A.E.'.
