If, then, we take our stand at the moment when Claudius began to reign, and count a century backwards, it is impossible to mention a time when philosophy was more impotent for good, and when the higher classes of the Roman empire were more thoroughly irreligious and unbelieving. To understand the reason of this we must take into account first the negative and then the positive action of philosophy up to that time. As to the former, there can be no doubt that the effect of philosophy in all its schools and through all its shades of thought had been hostile to a simple belief in polytheism and its mythology. Human reason had been turned with pitiless severity on its mass of fables, its discreditable stories, its manifold contradictions. As early as the sixth century before Christ it had used the key of allegory in order to infuse into these some better meaning, and this was carried out into full detail by Metrodorus, a follower of Anaxagoras. Thus if Homer, the mirror in which the Greek saw his religion reflected, described Jupiter as suspending Juno between heaven and earth, Heracleitus was indignant with the atheists who did not see that it meant how the world and the elements were formed.(448) By this process indecent personal agencies melted away into physical effects, or were even sublimated into moral lessons. Men were told that only soft Phæacians could see in the loves of Mars and Venus a consecration of adultery: to the man of sense it meant that valour and beauty were worthy of each other. Through all the following centuries this tone of mind continued. As to the stoical philosophers in particular, this physical allegorising was the perpetual instrument by which they reconciled their stern system of material Pantheism with all the stage scenery of the poet’s Olympus. Epicurus, on the contrary, recognised the existence of gods in countless numbers, but they were beings who lived in the enjoyment of his philosophy, far removed from the cares of providence and the thought of human things. On the other hand, Plato’s attempt to purify, while he recognised, polytheism, and to sweep away all its fables as purveyors of evil thoughts and desires, found little success, though his conception of the godhead as the Idea of goodness, remained the highest ever reached in that long process of thought; and through all this period the best and purest minds found in him a support against that bewilderment of the reason which the vulgar religion inflicted on them. But few and far between were those who followed Plato in this his highest conception, while the literature of that last century, in the midst of which Christ appeared, remains an abiding proof that the critical, scoffing, negative spirit of philosophy had spread itself over all the cultured classes. We seek in vain in Julius Cæsar and Cicero, in Lucretius, Catullus, Virgil, Manilius, Horace, Ovid, in Polybius, Dionysius, Diodorus, or Strabo, for
