of giving to Evil a necessary existence, that is to say, an independent and eternal existence. Now, Bayle has very well proved, by attacking this system through that of Manes, that two opposed Principles cannot exist equally eternal and independent of one another, because the clearest ideas of order teach us that a Being which exists by itself, which is necessary, which is eternal, must be unique, infinite, all-powerful, and endowed with all manner of perfections.[303] But it is not at all certain that Plato may have had the idea that his disciples have attributed to him, since far from considering matter as an independent and necessary being, animated by a soul essentially bad, he seems even to doubt its existence, going so far as to regard it as pure nothingness, and calls the bodies which are formed of it, equivocal beings holding the medium between what is always existing and what does not exist at all[304]; he affirms sometimes that matter has been created and sometimes that it has not been[305]; and thus falls into contradictions of which his enemies have taken advantage. Plutarch, who has clearly seen it, excuses them by saying that this great philosopher has fallen into these contradictions designedly, in order to conceal some mystery; a mind constructed like his not being made to affirm two opposites in the same sense.[306] The mystery that Plato wished to conceal, as he makes it sufficiently understood,[307] was the origin of Evil. He himself declares that he has never revealed and that he never will reveal, in writing, his real sentiments in this respect. Thus what Chalcidius and after him André Dacier have given concerning the doctrine of Plato are only conjectures or very remote inferences drawn from certain of his dogmas. One has often made use of this means, with regard to celebrated men whose writings one comments upon and particularly when one has certain reasons for presenting one’s ideas _sous un côté_ which outlines or which favours an opinion either favourable or unfavourable. It is this which happened more to Manes than to any other; his doctrine concerning the two Principles has been greatly calumniated, and without knowing just what he meant by them, one hastened to condemn him without investigating what he had said; adopting as axioms that he had laid down, inferences the most bizarre and most ridiculous that his enemies had drawn from certain equivocal phrases.[308] What persuades me to make this observation, is because it has been proved that Manes had indeed admitted two opposed Principles of Good and Evil, eternal independents, and holding of themselves their proper and absolute existence, since it is easy to see that Zoroaster, whose doctrine he had principally imitated, had not admitted them as such, but as equally issued from a superior Cause, concerning the essence of which he was silent.[309] I am very much inclined to believe that the Christian doctors who have
