It follows, however, that all early Atheism, so-called, was only the rejection of theistic ideas from some part of the business of life. The Christians were "Atheists" for the Pagan multitude, because they rejected the only God-ideas which the Pagan multitude harboured. In the same way the Christians who later scouted the worship of images of God (as Persians and Jews had done long before) were Atheists for those Christians who could only conceive of an imaged God. Prejudice has its own logic. When again medical men rested more and more on inductive method and rational (even if mistaken) procedure, and less and less on sorcery and invocation, they were naturally called Atheists, because they excluded "God" from an important and perilous province of action. Logically, the more a man is a Theist, the more of "God's" intervention he sees in life. No man is a Theist in all things; but in the ages of ignorance men were theistic in most matters. The kingdom of God, in a practical sense, is a sphere in which man is confessedly ignorant or impotent. "God's will" is the name for the forces which man cannot control, and does not understand. It covers a storm, a pestilence, a good or bad harvest, a stroke of luck, but not an indigestion, or the breaking of coal when struck by a hammer. Thus it is that every new advance of science, every new explanation of a body of facts in terms of law and innate tendency, is at first denounced as Atheistic. After the physicians came the physicists. The great Kepler, in keeping with his idealistic method, was so steeped in Theism as to fancy that the planets were kept up to time by guiding angels. Newton, however, was flatly accused of Atheism for explaining the universe in terms of the law of gravitation. He had driven God out of the world, it was said; and so far as his physics went, it was true. Yet he himself was an ardent Theist; and he even sought to make good his Theism by the theory that "matter" was first without gravitation, and that God added the attribute. With or without this safeguard, however, Newton's generalisation was sufficiently abstract to leave popular religion intact; and practical Theism even assimilated and gained by his science. It was not till geologists began to explain the formation of the earth in terms of law and tendency that the great shock came. God had hitherto been generally conceived as shaping the earth, were it only because there was no other explanation at hand; and, above all, geology clashed with Genesis. Hence a much more serious resistance, and a much more general imputation of Atheism; though the first geologists were mostly Deists, and believers in the special creation of animal life. The next and the most serious shock was that given by Darwinism, which removed "the divine idea" from biology. Over this came the loudest outcry of all; and the odium would have been overwhelming were it not for the number of naturalists who took up the new doctrine
