The study of social progress is to-day not less needed in literature than is the analysis of the human heart. We live in an age of universal investigation, and of exploration of the sources of all movements. France, for example, loves at the same time history and the drama, because the one explores the vast destinies of humanity, and the other the individual lot of man. These embrace the whole of life. But it is the province of religion, of philosophy, of pure poetry only, to go beyond life, beyond time, into eternity.
