The explanation of this anomaly is, we believe, to be found in the fact that Catholicism did, to a great extent, actually spring from a continuation of those widely different tendencies which Epicurus confounded in a common assault. It had an intellectual basis in the Platonic and Stoic philosophies, and a popular basis in the revival of those manifold superstitions which, underlying the brilliant civilisations of Greece and Rome, were always ready to break out with renewed violence when their restraining pressure was removed. The revival of which we speak was powerfully aided from without. The same movement that was carrying Hellenic culture into Asia was bringing Oriental delusions by a sort of back current into the Western world. Nor was this all. The relaxation of all political bonds, together with the indifference of the educated classes, besides allowing a rank undergrowth of popular beliefs to spring up unchecked, surrendered the regulation of those beliefs into the hands of a profession which it had hitherto been the policy of every ancient republic to keep under rigid restraint—the accredited or informal ministers of religion.[154] Now, the chief characteristic of a priestly order has always and everywhere been insatiable avarice. When forbidden to acquire wealth in their individual capacity, they grasp at it all the more eagerly in their corporate capacity. And, as the Epicureans probably perceived, there is no engine which they can use so effectually for the gratification of this passion as the belief in a future life. What they have to tell about this is often described by themselves and their supporters as a message of joy to the weary and afflicted. But under their treatment it is very far from being a consolatory belief. Dark shades and lurid lights predominate considerably in their pictures of the world beyond the grave; and here, as we shall presently show, they are aided by an irresistible instinct of human nature. On this subject, also, they can speak with unlimited confidence; for, while their other statements about the supernatural are liable to be contradicted by experience, the abode of souls is a bourne from which no traveller returns to disprove the accuracy of their statements. That such a tendency was at work some time before the age of Epicurus is shown by the following passage from Plato’s _Republic_:—
