To such a task the critic may lend himself without arousing our antagonism. We have no pressing need to know the latent possibilities of emotion for us in a book or a poem; but whether it is excellent or the reverse, whether "we were right in being moved by it," we are indeed willing to hear, for we desire to justify the faith that is in us. If, then, the office of the judge be an essential part of the critical function, the appreciative critic, whatever his other merits,--and we shall examine them later,--fails at least of perfection. His scheme is not the ideal one; and we may turn back, in our search for it, to a closer view of those which his was to supersede. Impressionism, however, is at once out of the running; it has always vigorously repudiated the notion of the standard, and we know, therefore, that no more than appreciation can it choose its material and stand alone. But scientific criticism professes, at least, the true faith M. Brunetiere holds that his own method is the only one by which an impersonal and stable judgment can be rendered. The doctrine of the evolution of literary species is more or less explained in naming it. Literary species, M. Brunetiere maintains, do exist. They develop and are transformed into others in a way more or less analogous to the evolution of natural types. It remains to see on what basis an objective judgment can be given. Although M. Brunetiere seems to make classification the disposal of a work in the hierarchy of species, and judgment the disposal of it in relation to others of its own species, he has never sharply distinguished between them; so that we shall not be wrong in taking his three principles of classification, scientific, moral, and aesthetic, as three principles by which he estimates the excellence of a work. His own examples, indeed, prove that to him a thing is already judged in being classified. The work of art is judged, then, by its relation to the type. Is this position tenable? I hold that, on the contrary, it precludes the possibility of a critical judgment; for the judgment of anything always means judgment with reference to the end for which is exists. A bad king is not the less a bad king for being a good father; and if his kingship is his essential function, he must be judged with reference to that alone. Now a piece of literature is, with reference to its end, first of all a work of art. It represents life and it enjoins morality, but it is only as a work of art that it attains consideration; that, in the words of M. Lemaitre, it "exists" for us at all. Its aim is beauty, and beauty is its excuse for being.
