Excerpt: "The beginning of the victorious career of modern science was very largely due to the making of two stimulating discoveries at the close of the Middle Ages. One was the discovery of the earth: the other the discovery of the universe. Men were confined, like molluscs in their shells, by a belief that they occupied the centre of a comparatively small disk—some ventured to say a globe—which was poised in a mysterious way in the middle of a small system of heavenly bodies. The general feeling was that these heavenly bodies were lamps hung on a not too remote ceiling for the purpose of lighting their ways. Then certain enterprising sailors—Vasco da Gama, Maghalaes, Columbus—brought home the news that the known world was only one side of an enormous globe, and that there were vast lands and great peoples thousands of miles across the ocean. The minds of men in Europe had hardly strained their shells sufficiently to embrace this larger earth when the second discovery was reported. The roof of the world, with its useful little system of heavenly bodies, began to crack and disclose a profound and mysterious universe surrounding them on every side. One cannot understand the solidity of the modern doctrine of the formation of the heavens and the earth until one appreciates this revolution."
Joseph Martin McCabe (12 November 1867 – 10 January 1955) was an English writer and speaker on freethought, after having been a Roman Catholic priest earlier in his life. He was "one of the great mouthpieces of freethought in England". Becoming a critic of the Catholic Church, McCabe joined groups such as the Rationalist Association and the National Secular Society. He criticised Christianity from a rationalist perspective, but also was involved in the South Place Ethical Society which grew out of dissenting Protestantism and was a precursor of modern secular humanism.
