groaning under the incubus of superstitions which he alone could teach them to shake off. He seems, indeed, to have confounded the old and the new faiths under a common opprobrium, and to have assumed that the popular religion was mainly supported by Stoic arguments, or that the Stoic optimism was not less productive of superstitious terrors than the gloomy polytheism which it was designed to supersede.[152] Again, while attacking the belief in human immortality, Epicurus seems to direct his blows against the metaphysical reasonings of Plato,[153] as well as against the indistinct forebodings of primitive imagination. The consequences of this two-edged polemic are very remarkable. In reading Lucretius, we are surprised at the total absence of criticisms like those brought to bear on Greek mythology with such formidable effect, first by Plato and, long afterwards, by Lucian. There is a much more modern tone about his invectives, and they seem aimed at an enemy familiar to ourselves. One would suppose that the advent of Catholicism had been revealed in a prophetic vision to the poet, and that this, rather than the religion of his own times, was the object of his wrath and dread; or else that some child of the Renaissance was seeking for a freer utterance of his own revolt against all theology, under the disguise of a dead language and of a warfare with long-discredited gods. For this reason, Christians have always regarded him, with perfect justice, as a dangerous enemy; while rationalists of the fiercer type have accepted his splendid denunciations as the appropriate expression of their own most cherished feelings.
