HISTORY.

The course of human thought could be traced in the parallel development of these two sides of knowledge. " Mathematics" the measurable, exact, settled. "History" the changing, the subjective, the matter of constant enquiry. "History "retains this vague developing connotation. This quite properly used of the account of one man's life, the history of Napoleon. Accepting this definition, it is at once clear that History is the central thread of social science; widely interpreted it embraces the whole. But for convenience of study, one need to distinguish the different aspects and preserve the autonomy of those sciences on which history is based. Thus to take the two succeeding subjects in this Conference, Geography and Biology, they have in them two great ranges of facts which condition human progress, but are not subject to Man's will. "History" is thus in touch at the highest level with Ethics as it is on the lower with the sciences of nature. It is even more truly the evolution of Morality than it is an offshoot of Earth-knowledge.
