CHAPTER IV

THE POPULATION PROBLEM AMONG MEN 80

(1) The population problem among men has, owing to the evolution of reason, assumed in both aspects a wholly different form. (2) To follow the nature, causes, and results of these changes a sketch is required of human evolution—especially of social evolution. History only provides a partial record for a few thousand years, and (3) we are thus dependent for social history upon our knowledge of primitive races which may be applied to prehistoric races. (4) Outline of future chapters.
