Note 291 — Chapter V · FREETHOUGHT IN GREECE

It is clear, nevertheless, if we can be sure of his writings, that he was a monotheist, but a monotheist with no practical religion. “Excluding such a thing as divine interference with Nature, his theology, of course, excludes the possibility of revelation, inspiration, miracles, and grace.”291 In a passage in the Metaphysics, after elaborating his monistic conception of Nature, he dismisses in one or two terse sentences the whole current religion as a mass of myth framed to persuade the multitude, in the interest of law and order.292 His influence must thus have been to some extent, at least, favourable to rational science, though unhappily his own science is too often a blundering reaction against the surmises of earlier thinkers with a greater gift of intuition than he, who was rather a methodizer than a discoverer.293 What was worst in his thinking was its tendency to apriorism, which made it in a later age so adaptable to the purposes of the Roman Catholic Church. Thus his doctrines of the absolute levity of fire and of nature’s abhorrence of a vacuum set up a hypnotizing verbalism, and his dictum that the earth is the centre of the universe was fatally helpful to Christian obscurantism. For the rest, while guiltless of Plato’s fanaticism, he had no scheme of reform whatever, and was as far as any other Greek from the thought of raising the mass by instruction. His own science, indeed, was not progressive, save as regards his collation of facts in biology; and his political ideals were rather reactionary; his clear perception of the nature of the population problem leaving him in the earlier attitude of Malthus, and his lack of sympathetic energy making him a defender of slavery when other men had condemned it.294 He was in some aspects the greatest brain of the ancient world; and he left it, at the close of the great Grecian period, without much faith in man, while positing for the modern world its vaguest conception of Deity. Plato and Aristotle between them had reduced the ancient God-idea to a thin abstraction. Plato would not have it that God was the author of evil, thus leaving evil unaccounted for save by sorcery. Aristotle’s God does nothing at all, existing merely as a potentiality of thought. And yet upon those positions were to be founded the theisms of the later world. Plato had not striven, and Aristotle had failed, to create an adequate basis for thought in real science; and the world gravitated back to religion.
