of some sacred and immutable principle. Forty-nine gods accordingly exist; but no more. For, since the essence of each is to be the governing ideal of a motion, the number of motions in the sky determines the number of divine first principles. The gods, we see, are still the souls of Nature; a soul without a body would be a principle without an application; there can be no gods, then, without a phenomenal function, no gods that do not appear in the operations of Nature. This astronomic mythology was surely not less poetical than that of Homer, even if, by virtue of a certain cold and abstract purity, not unworthy of the stars of which it spoke, it was more difficult and sublime. We may observe in it a last application of the ancient mythological method by which the phenomena of Nature became evidence of the existence and character of the gods. But the celestial deities of Aristotle, and the minor creative gods of Plato that correspond to them, retained too much poetic individuality for the still poorer imagination of later times. The most religious of sects during the classical decadence was that of the Stoics; in them the spirit of conformity, which is a chief part even of the religions of hope, constituted by its exclusive cultivation a religion of despair. The name of Zeus, and an equally equivocal use of the word "reason" to designate the regularity of Nature, served to disguise the alien brutality of the power or law to which all the gods had been reduced. Against the background of a materialistic pantheism, in which Stoic speculation culminated, two positive interests stood out: one, the resolute and truly human courage with which the Stoic faced the reality as he conceived it, and kept his dignity and his conscience pure although heaven might fall; the other, the efforts he made, in his need for religion, to rejuvenate and reinterpret the pagan forms. The fables he turned into ethical allegories, the oracles, auspices, and other superstitious rites, he transformed into quasi-scientific ways of reading the book of Nature and forecasting events. This possibility of prophecy constituted the Stoic "providence" which the sentimentality of modern apologists has been glad to confuse with the benevolent Providence of Christian dogma, a Providence making for the salvation of men. The Stoic providence excluded that essential element of benevolence; it was merely the fact that Nature was prophetic of her own future, that her parts, both in space and in time, were magically composed into one living system. Mythology thus ended with the conception of a single god whose body was the whole physical universe, whose fable was all history, and whose character was
