One can see by these few words that the ancient sages did not give to Destiny the universal influence that certain philosophers and particularly the Stoics gave to it later on; but they considered it only as exercising its empire over matter. It is necessary to believe that since the followers of the Porch had defined it as a chain of causes, by virtue of which the past has taken place, the present exists, and the future is to be realized[298]; or still better, as the rule of the law by which the Universe is governed[299]; one must believe, I say, that these philosophers confounded Destiny with Providence, and did not distinguish the effect from its cause, since these definitions conform only with the fundamental law of which destiny is but an emanation. This confusion of words had to produce and in fact did produce, among the Stoics, an inversion of ideas which was the most unfortunate result[300]; for, as they established, according to their system, a chain of good and evil that nothing could either alter or break, one easily inferred that the Universe being subject to the attraction of a blind fatality, all actions are here necessarily determined in advance, forced, and thereafter indifferent in themselves; so that good and evil, virtue and vice, are vain words, things whose existence is purely ideal and relative. The Stoics would have evaded these calamitous results if, like Pythagoras, they had admitted the two motives of which I have spoken, Necessity and Power; and if, far from instituting Necessity alone as absolute master of the Universe, under the name of Destiny or Fatality, they had seen it balanced by the Power of the Will, and subject to the Providential Cause whence all emanates. The disciples of Plato would also have evaded many errors, if they had clearly understood this concatenation of the two opposed principles, from which results universal equilibrium; but following certain false interpretations of the doctrine of their master regarding the soul of matter, they had imagined that this soul was no other than Necessity by which it is ruled[301]; so that, according to them, this soul being inherent in matter, and bad in itself, gave to Evil a necessary existence: a dogma quite formidable, since it makes the world to be considered as the theatre of a struggle without beginning or end, between Providence, principle of Good, and the soul of matter, principle of Evil. The greatest mistake of the Platonists, exactly contrary to that of the Stoics, was in having confused the free power of the Will with the divine Providence, in having instituted it for the principle of good and thus being put in position of maintaining that there are two souls in the world, a beneficent one, God, and a malefic one, Matter. This system, approved of by many celebrated men of antiquity and which Beausobre assures was the most widely received,[302] offers, as I have observed, the very great disadvantage
