Returning once more to Epicurus, we have now to sum up the characteristic excellences and defects of his philosophy. The revival of the atomic theory showed unquestionable courage and insight. Outside the school of Democritus, it was, so far as we know, accepted by no other thinker. Plato never mentions it. Aristotle examined and rejected it. The opponents of Epicurus himself treated it as a self-evident absurdity.[208] Only Marcus Aurelius seems to have contemplated the possibility of its truth.[209]. But while to have maintained the right theory in the face of such universal opposition was a proof of no common discernment, we must remember that appropriating the discoveries of others, even when those discoveries are in danger of being lost through neglect, is a very different thing from making discoveries for one’s self. No portion of the glory due to Leucippus and Democritus should be diverted to their arrogant successor. And it must also be remembered that the Athenian philosopher, by his theory of deflection, not only spoiled the original hypothesis, but even made it a little ridiculous. The second service of Epicurus was entirely to banish the idea of supernatural interference from the study of natural phenomena. This also was a difficult enterprise in the face of that overwhelming theological reaction begun by Socrates, continued by Plato, and carried to grotesque consequences by the Stoics; but, here again, there can be no question of attributing any originality to the philosopher of the Garden. That there either were no gods at all, or that if there were they never meddled with the world, was a common enough opinion in Plato’s time; and even Aristotle’s doctrine of a Prime Mover excludes the notion of creation, providence, and miracles altogether. On the other hand, the Epicurean theory of idle gods was irrational in itself, and kept the door open for a return of superstitious beliefs.
