THE “CONFLICT BETWEEN RELIGION AND SCIENCE,” which was much discussed after the appearance of Darwin’s “Origin of Species,” ceased to be considered a topic of engrossing interest after the appearance of Professor Henry Drummond’s “Natural Law in the Spiritual World.” Being an advanced Darwinian and at the same time a Christian evangelist of the school of Dwight L. Moody, Professor Drummond calmly assumed the impossibility of such a conflict having a real existence; and though it cannot be said that he demonstrated or attempted to demonstrate anything, his great learning and the calmness of his well-assured convictions had a decided effect. He was born at Stirling, Scotland, in 1851, and his scientific work was done chiefly while professor of Natural History and Science in the Free Church College, Glasgow. His religious addresses have had an extraordinary popular circulation both in England and America. One of them, “The Greatest Thing in the World,” has been described as the “Oration on the Crown” of the modern pulpit.
