In 1884, American historian and philosopher John Fiske published The Destiny of Man, which discussed humanity's origin, destiny and place in the universe. A leading populariser of Darwin's theory in the United States and influenced by Herbert Spencer, Fiske considers views of human progress via evolutionary social change and the harmony between science and religion. The Destiny of Man is composed of sixteen chapters that anticipate philosophical questions from a typical non-scientific audience: the origins of atheism, the shifting hierarchal positions of humanity through history as proposed by Copernicus and later by Darwin, human brain size, and the 'dawning of consciousness' as a result of the growth and development of moral sentiment and inventiveness through natural selection. Interestingly, at the end of the book, Fiske discusses the historical power relationships of ruling governments and predicts that as humans evolve and become more civilised, war will eventually end.
