||Throughout history the great problem has been the relation of Man to the Universe, but until modern times the Universe was the important subject of though and Man, only an incident. With the advent of Christianity, however, this attitude was changed, and Man as an individual with a claim to divinity gradually emerged. By the Eighteenth Century, Pope in his "Essay on Man", sounded the sentiment of the race through the coming centuries: "Know then thyself, presume not God to scan, The proper study of mankind is man." Partly then as a result of this evolution in thought, and partly as the result of revolution, Man, the individual, in his economic, social and ethical relations is the great factor in the life and thought of the Nineteenth and the Twentieth Centuries. And probably tow of the greatest preachers of the divinity of man and the value of his life are Thomas Carlyle and Ralph Waldo Emerson. Men whose lives extended almost throughout the Nineteenth Century, but who influence cannot be estimated.
