THREE:If Plotinus rose above the vulgar superstitions of the West, while, at the same time, using their language for the easier expression of his philosophical ideas, there was one more refined superstition of mixed Greek and Oriental origin which he denounced with the most uncompromising vigour. This was Gnosticism, as taught by Valentinus and his school. Towards the close of our last chapter, we gave some account of the theory in question. It was principally as enemies of the world and maligners of its perfection that the Gnostics made themselves offensive to the founder of Neo-Platonism. To him, the antithesis of good and evil was represented, not by the opposition of spirit and Nature, but by the opposition between his ideal principle through all degrees of its perfection, and unformed Matter. Like Plato, he looked on the348 existing world as a consummate work of art, an embodiment of the archetypal Ideas, a visible presentation of reason. But in the course of his attack on the Gnostics,518 other points of great interest are raised, showing how profoundly his philosophy differed from theirs, how entirely he takes his stand on the fixed principles of Hellenic thought. Thus he particularly reproaches his opponents for their systematic disparagement of Plato, to whom, after all, they owe whatever is true and valuable in their metaphysics.519 He ridicules their belief in demoniacal possession, with its wholly gratuitous and clumsy employment of supernatural agencies to account for what can be sufficiently explained by the operation of natural causes.520 And, more than anything else, he severely censures their detachment of religion from morality. On this last point, some of his remarks are so striking and pertinent that they deserve to be quoted.Moreover, the Platonic ideas were something more than figments of an imaginative dialectic. They were now beginning to appear in their true light, and as what Plato had always understood them to beno mere abstractions from experience, but spiritual forces by which sensuous reality was to be reconstituted and reformed. The Church herself seemed366 something more than a collection of individuals holding common convictions and obeying a common discipline; she was, like Platos own Republic, the visible embodiment of an archetype laid up in Heaven.533 And the Churchs teaching seemed also to assume the independent reality of abstract ideas. Does not the Trinity involve belief in a God distinct from any of the Divine Persons taken alone? Do not the Fall, the Incarnation, and the Atonement become more intelligible if we imagine an ideal humanity sinning with the first Adam and purified by becoming united with the second Adam? Such, at least, seems to have been the dimly conceived metaphysics of St. Paul, whatever may now be the official doctrine of Rome. It was, therefore, in order that, during the first half of the Middle Ages, from Charlemagne to the Crusades, Realism should have been the prevailing doctrine; the more so because Platos Timaeus, which was studied in the schools through that entire period, furnishes its readers with a complete theory of the universe; while only the formal side of Aristotles philosophy is represented by such of his logical treatises as were then known to western Christendom.
