IT is not so long ago that the field of literary criticism was divided into two opposing camps. France being the only country in the world where criticism is a serious matter, the battle waged most fiercely there, and doubtless greatly served to bring about the present general interest and understanding of the theoretical questions at issue. The combatants were, of course, the impressionistic and scientific schools of criticism, and particularly enlightening were the more or less recent controversies between MM. Anatole France and Jules Lemaitre as representatives of the first, and M. Brunetiere as the chief exponent of the second. They have planted their standards; and we see that they stand for tendencies in the critical activity of every nation. The ideal of the impressionist is to bring a new piece of literature into being in some exquisitely happy characterization, - to create a lyric of criticism out of the unique pleasure of an aesthetic hour. The stronghold of the scientist, on the other hand, is the doctrine of literary evolution, and his aim is to show the history of literature as the history of a process, and the work of literature as a product; to explain it from its preceding causes, and to detect thereby the general laws of literary metamorphosis.Such are the two great lines of modern criticism; their purposes and ideals stand diametrically opposed. Of late, however, there have not been wanting signs of a spirit of reconciliation, and of a tendency to concede the value, each in its own sphere, of different but complementary activities. Now and again the lion and the lamb have lain down together; one might almost say, on reading a delightful paper of Mr. Lewis E. Gates on Impressionism and Appreciation, that the lamb had assimilated the lion. For the heir of all literary studies, according to Professor Gates, is the appreciative critic; and he it is who shall fulfill the true function of criticism. He is to consider the work of art in its historical setting and its psychological origin, "as a characteristic moment in the development of human spirit, and as a delicately transparent illustration of aesthetic law." But, "in regarding the work of art under all these aspects, his aim is, primarily, not to explain, and not to judge or dogmatize, but to enjoy; to realize the manifold charms the work of art has gathered unto itself from all sources, and to interpret this charm imaginatively to the men of his own day and generation."Thus it would seem that if the report of his personal reactions to a work of literary art is the intention of the impressionist, and its explanation that of the scientist, the purpose of the appreciative critic is fairly named as the illuminating and interpreting reproduction of that work, from material furnished by those other forms of critical activity. Must, then, the method of appreciation, as combining and reconciling the two opposed views, forthwith claim our adherence? To put to use all the devices of science and all the treasures of scholarship for the single end of imaginative interpretation, for the sake of giving with the original melody all the harmonies of subtle association and profound meaning the ages have added, is, indeed, a great undertaking. But is it as valuable as it is vast
