Demon of Spleen or to the Blue Devils only the sombre elements of that soulful compound, which, however, the evil imps would eternally tend to make as absolutely dyspeptic and like unto themselves as its primordial texture would allow. In exactly such a way Plato, in his allegorical manner, constructed a universe with a poetical machinery of moral forces, personified and treated as agents. When the thin veil of allegory is drawn aside, there remains nothing but a splendid illustration of the Socratic philosophy; we are taught that the only science is moral science, and that, if we wish to understand the world, we must bend our minds to the definition of its qualities and values, which are all that is intelligible in it. Essences and values alone are knowable and fixed and amenable to science. If we insist on history and cosmogony, we must be satisfied with having them presented to us in allegorical form, and made to follow ethics as the Timæus follows the Republic. Natural philosophy can be nothing but a sort of analytic retrospect by which we trace the first glimmerings and the progressive manifestation in Nature of those ideas which have authority over our own minds.

Phenomena had for Plato existence without reality, that is, without intelligibility or value. They were a mere appearance. We need not be surprised, then, that he refused altogether to construct a theology by the poetic interpretation of phenomena and preferred to construct one allegorically out of his moral conceptions, the good and the ideal. Aristotle, too, while adhering incidentally, as we have seen, to a purified astronomical theology, capped this with a purified moral theology of his own. The Platonic picture-gallery of ideas, with the abstract principle of excellence that unified them, gave place in his philosophy to an Ideal realized in the concrete and existing as an individual. We may venture to say that among the thinkers of all nations Aristotle was the first to reach the conception of what may fitly be called God. Neither the national deity of the Hebrews, as then conceived, nor the natural deities of the Gentiles, nor the half-physical, half-logical abstractions of the earlier Greek philosophers really corresponded to the notion of a being spiritual, personal, and perfect, immutable without being abstract, and omnipotent without effort and without degradation. Aristotle first constructed this ideal, not out of his fancy, but by building on the solid ground of human nature and following to their point of union the lines which moral aspiration and effort actually follow. Nay, the ideal he pointed to was to be the goal not of human life only but of natural life in all its forms. The analytic study of Nature (a study which at
