As an assistant to Dwight L. Moody, the great 19th-century evangelist, college science lecturer Henry Drummond found expression for his religious yearnings. But with this 1883 bestseller, he secured fame of his own by combining the spiritual and the scientific in one of the first great reconcilings of the natural and the soulful. By exploring such concepts as birth, growth, death, the environment, and eternal life from both the perspectives of both reason and faith, and demonstrating how the two standpoints are not mutually exclusive, Drummond offered readers hungry for a new understanding of the human experience a way to a new and thoroughly modern philosophy of life, one that continues to have a profound impact on readers today. Scottish evangelist HENRY DRUMMOND (1851-1897) also wrote the influential The Ascent of Man (1894), a Christian assessment of Darwin’s impact on spirituality, and The Greatest Thing in the World (1880), a meditation on Scripture that continues to deeply move readers today.
