As well as an evangelist and missionary, Henry Drummond was a naturalist. He studied physical and mathematical science before dedicating himself fully to Christian ministry. In 1877, he became a lecturer on natural science at the Free Church College. He used his position to share his faith as often as he could. While he studied in preparation for his lectures, Drummond wrote Natural Law in the Spiritual World, in which he explores how the world of religion and spirituality relates to the physical world. He argued that the disconnect between the spiritual and the physical was entirely illusory and that faith was by no means in conflict with science. Written just a few decades after Darwin’s landmarkOn the Origin of Species, Drummond’s reconciliation of the theory of evolution with God’s purposes ranks among the most important and influential books concerning Christian faith and scientific progress.

Henry Drummond was a Scottish scientist, Free Church minister, explorer and evangelist who became one of the most influential religious figures of the Victorian era. Written as a means of clarifying his own thoughts on the clash between science and religion, Natural Law and the Spiritual World was published in 1883 to great critical acclaim. Entering the debate on science and religion using the basis of law, Drummond sets himself apart by offering ‘a property peculiar neither to science nor religion’. He puts forward the argument that the laws of the natural and spiritual worlds are not completely separate, and explores the connections between them. He concludes by suggesting that the scientific principle of continuity extends from the physical world to the spiritual, offering common ground to people on both sides of the science/religion divide. http://www.cambridge.org/
