I do not believe finally in this or that “theory” of criticism. There are as many sound and apt species of criticism as there are works to be criticized. To say that art must be criticized only after this formula or after that, is to say that art must be contrived only out of this formula or out of that. As every work of art is an entity, a thing in itself, so is every piece of criticism an entity, a thing in itself. That “Thus Spake Zarathustra” must inevitably be criticized by the canons of the identical “theory” with which one criticizes “Tristan and Isolde” is surely difficult of reasoning. To the Goethe-Carlyle doctrine that the critic’s duty lies alone in discerning the artist’s aim, his point of view and, finally, his execution of the task before him, it is easy enough to subscribe, but certainly this is not a “theory” of criticism so much as it is a foundation for a theory. To advance it as a theory, full-grown, full-fledged and flapping, as it has been advanced by the Italian Croce and his admirers, is to publish the preface to a book without the book itself. Accepted as a theory complete in itself, it fails by virtue of its several undeveloped intrinsic problems, chief among which is its neglect to consider the undeniable fact that, though each work of art is indubitably an entity and so to be considered, there is yet in creative art what may be termed an æsthetic genealogy that bears heavily upon comprehensive criticism and that renders the artist’s aim, his point of view and his execution of the task before him susceptible to a criticism predicated in a measure upon the work of the sound artist who has just preceded him. The Goethe-Carlyle hypothesis is a little too liberal. It calls for qualifications. It gives the artist too much ground, and the critic too little. To discern the artist’s aim, to discern the artist’s point of view, are phrases that require an amount of plumbing, and not a few foot-notes. It is entirely possible, for example, that the immediate point of view of an artist be faulty, yet the execution of his immediate task exceedingly fine. If carefully planned triumph in art is an entity, so also may be undesigned triumph. I do not say that any such latter phenomenon is usual, but it is conceivable, and hence may be employed as a test of the critical hypothesis in point. Unschooled, without aim or point of view in the sense of this hypothesis, Schumann’s compositions at the age of eleven for chorus and orchestra offer the quasi-theory some resistance. The question of the comparative merit of these compositions and the artist’s subsequent work may not strictly be brought into the argument, since the point at issue is merely a theory and since theory is properly to be tested by theory.
