Henry Drummond, author and evangelist, was born at Stirling, Scotland, in 1851. His book, "Natural Law in the Spiritual World," caused much discussion and is still widely read. His "Ascent of Man" is regarded by many as his greatest work. The address reprinted here has appeared in hundreds of editions, and has been an inspiration to thousands of peoples all over the world. There is an interesting biography of Drummond by Professor George Adam Smith, his close friend and colaborer. He died in 1897.
