Mr. Emerson is right enough in making the sensible copy or imitate the intelligible, what there is true in Swedenborg's doctrine of correspondences; but wrong in making the mimetic purely phenomenal, unreal, a mere sense-show. The mimetic, the mimesis, by which Plato means the individual and the sensible, the variable and the transitory, is not the only real, nor the highest real, as sensists and materialists hold; but is as real in its order and degree as the methexic or ideal. Hence, St. Thomas is able to maintain that the sensible species, or accidents, as he calls them, can subsist without their subject, or, as we would say, the sensible body without the intelligible body; and therefore, that the doctrine of transubstantiation involves no contradiction; for it is not pretended that the sensible body undergoes any change, or that the sensible body of our Lord is present in the blessed eucharist. So St. Augustine distinguishes the visible--the sensible--body and the spiritual--intelligible--body, and holds both to be real. The individual is as real as the species--the _socratitas_, in the language of the schoolmen, as the _humanitas_--for neither is possible without the other. The sort of idealism, as it is called, that resolves the individual into the species, or the sensible into the intelligible, and thus denies the external world, is as unphilosophical as the opposite doctrine, that resolves the species into the individual and the intelligible into the sensible. Even Plato, the supposed father of idealism, does not make the mimesis absolutely unreal. For, to say nothing of the preëxistent matter, the image, picture, which is the exact copy of its ideal prototype, is a real image, picture, or copy. But Mr. Emerson, if he recognizes the methexis at all, either confounds it with real and necessary being, or makes it purely phenomenal, and therefore unreal, as distinguished from real and necessary being. Methexis is a Greek word, and means, etymologically and as used by Plato, participation. Plato's doctrine is, that all inferior existences exist by participation of the higher, through the medium of what he calls the plastic soul, whence the Demiourgos of the Gnostics. His error was in making the plastic soul instead of the creative act of God the medium of the participation. Still, Plato made it the participation of ideas or the ideal, and, in the last analysis, of Him who is being in himself. Hence, he made a distinction, if not the proper distinction, between the methexis and God, or being by participation and the absolute underived being, or being in itself.
