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 are abandoned to themselves, and move in a direction the reverse of that originally imposed on them. It is in the latter cycle that Plato supposes us to be moving at present.[403] Again, after having been long content to explain the origin of evil by the resistance of inert matter to the informing power of ideal goodness, Plato goes a step further in his latest work, the Laws, and hazards the hypothesis of an evil soul actively counterworking the beneficent designs of God.[404] And we find the same idea subsequently taken up by Plutarch, who sees in it the most efficient means for exonerating God from all share in the responsibility for physical disorder and moral wrong.[405] But both master and disciple restricted the influence of their supposed evil soul within very narrow limits, and they would have repudiated with horror such a notion as that the whole visible world is a product of folly or of sin.
Gnostic pessimism marks the extreme point of aberration to which Greek thought was drawn by the attraction of Oriental superstition. How it was rescued from destruction by a new systematisation of its ancient methods and results will be explained in another chapter.

In conclusion, a few words may profitably be devoted to the question whether the rationalistic movement of our own age is likely to be followed by such another supernaturalist reaction as that which made itself so powerfully felt during the first centuries of Roman imperialism. There is, no doubt, a certain superficial resemblance between the world of the Caesars and the world in which we live. Everywhere we see aristocracies giving way to more centralised and equitable forms of government, the authority of which is sometimes concentrated in the hands of a single absolute ruler. Not only are the interests and wishes of the poorer and less educated classes consulted with increasing anxiety, but the welfare of women is engrossing the attention of modern legislators to an even greater extent than was the case with the imperial jurists. Facilities for travelling, joined to the far-reaching combinations of modern statesmanship and modern strategy, are every day bringing Europe into closer contact with the religious life of Asia. The decay of traditional and organised theology is permitting certain forms of spontaneous and unorganised superstition to develope themselves once more, as witness the wide diffusion of spiritism, which is probably akin to the demonology and witchcraft of earlier ages, and would, no doubt, be similarly persecuted by the priests,—who, as it is, attribute spiritualistic manifestations to diabolical agency,—had they sufficient power for the purpose. Lastly, corresponding to the syncretism of the Roman empire, we may observe a certain mixture and combination of religious principles, Catholic ideas being avowedly adopted by even the most latitudinarian Protestants, and Protestant influences entering into Catholicism, much more imperceptibly it is true, but probably to an equal extent.
The analogy between modern Europe and the Roman empire is, however, as we have already hinted, merely superficial. It has been shown in the course of our analysis that to ensure the triumph of superstition in the old world something more was necessary than the destruction of aristocratic government. Every feeling of liberty—except the liberty to die—and almost every feeling of self-respect had to be crushed out by the establishment of an authoritative hierarchy extending from the Emperor down to the meanest slaves, before the voice of Hellenic reason could be hushed. But among ourselves it is rather of the opposite fault—of too great independence and individualism—that complaints are heard. If we occasionally see a hereditary monarch or a popular minister invested with despotic power, this phenomenon is probably due to the circumstances of a revolutionary period, and will in course of time become more and more exceptional. Flatterers, parasites, and will-hunters are not an increasing but a diminishing class. Modern officers, as a body, show none of that contempt for reasoning and amenability to superstition which characterised the Roman centurions; in France, military men are even distinguished for their deadly hatred of priests. And, what is more important than any other element in our comparison, the reserves which modern civilisation is bringing to the front are of a widely different intellectual stature and equipment from their predecessors under Augustus and the Antonines. Since the reorganisation of industry by science, millions of working-men have received an education which prepares them to understand the universality of law much better than the literary education given to their social superiors, which, indeed, bears a remarkable resemblance to the rhetorical and sophistical training enjoyed by the contemporaries of Maximus Tyrius and Apuleius. If as much cannot be said of the middle classes, they are at any rate far more enlightened than Roman provincials, and are likely to improve still further with the spread of education—another peculiarly modern phenomenon. On this point we have, indeed, something better to argue from than à priori probabilities. We see before our eyes the rationalistic movement advancing pari passu with the democratic movement, and, in some countries, overtly aided by it. To say that this alliance has been provoked by an accidental and temporary association of monarchy and aristocracy with Church establishments, is a superficial explanation. The paid advocates of delusion know well where their interest lies. They have learned by experience that democracy means the education of the people, and that the education of the people means the loss of their own prestige. And they know also that, in many cases, the people are already sufficiently educated to use political power, once they have obtained it, for the summary destruction of organised and endowed superstition. What has been said of popular influence applies equally to the influence of women. When they were either not educated at all or only received a literary education, every improvement in their position was simply so much ground gained for superstition. The prospect is very different now. Women are beginning to receive a training like that of men, or rather a training superior to what all but a very few men have hitherto enjoyed. And the result is that, wherever this experiment has been tried, they have flung aside traditional beliefs once supposed to be a necessity of their nature even more decisively and disdainfully than have the professors by whom they are taught.
Once more, there was a cause of intellectual degeneration at work in the ancient world, which for us has almost ceased to exist. This was the flood of barbarism which enveloped and corrupted, long before it overwhelmed, the Hellenised civilisation of Rome. But if the danger of such an inundation is for ever removed, are we equally secure against the contagion of that intellectual miasma which broods over the multitudinous barbarian populations among whom we in turn are settling as conquerors and colonists? Anyone choosing to maintain the negative might point to the example of a famous naturalist who, besides contributing largely to the advancement of his own special science, is also distinguished for high general culture, but whom long residence in the East Indies has fitted to be the dupe of impostures which it is a disgrace even for men and women of fashion to accept. Experience, however, teaches us that, so far at least, there is little danger to be dreaded from this quarter. Instead of being prone to superstition, Anglo-Indian society is described as prevailingly sceptical or even agnostic; and, in fact, the study of theology in its lowest forms is apt to start a train of reflection not entirely conducive to veneration for its more modern developments. For the rest, European enlightenment seems likely to spread faster and farther among the conquered, than Oriental darkness among the conquering race.
So far, we have only considered belief in its relation to the re-distribution of political, social, and national forces. But behind all such forces there is a deeper and more perennial cause of intellectual revolution at work. There is now in the world an organised and ever-growing mass of scientific truths, at least a thousand times greater and a thousand times more diffused than the amount of positive knowledge possessed by mankind in the age of the Antonines. What those truths can do in the future may be inferred from what they have already done in the past. Even the elementary science of Alexandria, though it could not cope with the supernaturalist reaction of the empire, proved strong enough, some centuries later, to check the flood of Mahometan fanaticism, and for a time to lead captivity captive in the very strongholds of militant theological belief. When, long afterwards, Jesuitism and Puritanism between them threatened to reconquer all that the humanism of the Renaissance had won from superstition, when all Europe from end to end was red with the blood or blackened with the death-fires of heretics and witches, science, which had meanwhile been silently laying the foundations of a new kingdom, had but to appear before the eyes of men, and they left the powers of darkness to follow where she led. When the follies and excesses of the Revolution provoked another intellectual reaction, her authority reduced it to a mere mimicry and shadow of the terrible revenges by which analogous epochs in the past history of opinion had been signalised. And this was at a time when the materials of reaction existed in abundance, because the rationalistic movement of the eighteenth century had left the middle and lower classes untouched. At the present moment, Catholicism has no allies but a dispirited, half-sceptical aristocracy; and any appeal to other quarters would show that her former reserves have irrevocably passed over to the foe. What is more, she has unconsciously been playing the game of rationalism for fifteen centuries. By waging a merciless warfare on every other form of superstition, she has done her best to dry up the sources of religious belief. Those whom she calls heathens and pagans lived in an atmosphere of supernaturalism which rendered them far less apt pupils of philosophy than her own children are to-day. It was harder to renounce what she took away than it will be to renounce what she has left, when the truths of science are seen by all, as they are now seen by a few, to involve the admission that there is no object for our devotion but the welfare of sentient beings like ourselves; that there are no changes in Nature for which natural forces will not account; and that the unity of all existence has, for us, no individualisation beyond the finite and perishable consciousness of man.
