When we cast a glance upon the immense progress realized by the natural sciences in the course of the nineteenth century, and when we perceive the promises they contain for the future, we can not but feel deeply impressed by the idea that mankind is entering upon a new era of progress It has, at any rate, before it all the elements for preparing such a new era. In the course of the last one hundred years, new branches of knowledge, opening entirely new vistas upon the laws of the development of human society, have grown up under the names of anthropology prehistoric ethnology (science of the primitive social institutions), the history of religions, and so on. New conceptions about the whole life of the universe were developed by pursuing such lines of research as molecular physics, the chemical structure of matter, and the chemical composition of distant worlds.

The conception of struggle for existence as a factor of evolution, introduced into science by Darwin and Wallace, has permitted us to embrace an immensely wide range of phenomena in one single generalization, which soon became the very basis of our philosophical, biological, and sociological speculations. An immense variety of facts: -- adaptations of function and structure of organic beings to their surroundings; physiological and anatomical evolution; intellectual progress, and moral development itself, which we formerly used to explain by so many different causes, were embodied by...
