That Philo’s interpretation of Platonism ultimately reacted on Greek thought seems certain, but at what date his influence began to tell, and how far it reached, must remain undecided. Plutarch speaks of God’s purity and of his transcendent elevation above the universe in language closely resembling that of the Alexandrian Jew, with whose opinions he may have been indirectly acquainted.[400] We have already seen how the daemons were employed to fill up the interval thus created, and what serious concessions to popular superstition the belief in their activity involved. Still Plutarch does not go so far as to say that the world was not created by God. This step was taken by Numenius, a philosopher who flourished about the middle of the second century, and who represents the complete identification of Platonism with Pythagoreanism, already mentioned as characteristic of the period following that date. Numenius is acquainted with Philo’s speculations, and accepts his derivation of Platonism from the Pentateuch. ‘What,’ he asks, ‘is Plato but a Moses writing in the Attic dialect?’[401] He also accepts the theory that the world was created by a single intermediate agent, whom, however, he credits with a much more distinct and independent personality than Philo could see his way to admitting. And he regards the human soul as a fallen spirit whose life on earth is the consequence of its own sinful desires. From such fancies there was but a single step to the more thorough-going dualism which looks on the material world as entirely evil, and as the creation of a blind or malevolent power. This step had already been taken by Gnosticism. The system so called summed up in itself, more completely, perhaps, than any other, all the convergent or conflicting ideas of the age. Greek mythology and Greek philosophy, Zoroastrianism, Judaism, and Christianity each contributed an element to the fantastic and complicated scheme propounded by its last great representative, Valentinus. This teacher pitches his conception of the supreme God even higher than Philo, and places him, like Plato’s absolute Good, outside the sphere of being. From him—or it—as from a bottomless gulf proceed a vast series of emanations ending in the Demiurgus or creator of the visible world, whose action is described, in language vividly recalling the speculations of certain modern metaphysicians, as an enormous blunder. For, according to Gnosticism, the world is not merely infected with evil by participation in a material principle, it is evil altogether, and a special intervention of the higher powers is needed in order to undo the work of its delirious author.[402] Here we have a particular side of Plato’s philosophy exaggerated and distorted by contact with Zoroastrian dualism. In the _Statesman_ there is a mythical description of two alternate cycles, in one of which the world is governed by a wise providence, while in the other things
