(B) _Relations to History._ [Footnote: For a discussion of the
practical relations between the teaching of history and of sociology,
see my paper on "How History can be taught from a Sociological Point of
View," in Education for January, 1910.] A word may be said about the
relation of sociology to another science which also deals with human
society in a general way, and that is history. History is a concrete,
descriptive science of society which attempts to construct a picture of
the social past. Sociology, however, is an abstract, theoretical science
of society concerned with the laws and principles which govern social
organization and social change. In a sense, sociology is narrower than
history inasmuch as it is an abstract science, and in another sense it
is wider than history because it concerns itself not only with the
social past but also with the social present. The facts of contemporary
social life are indeed even more important to the sociologist than the
facts of history, although it is impossible to construct a theory of
social evolution without taking into full account all the facts
available in human history, and in this sense history becomes one of the
very important methods of sociology. Upon its evolutionary or dynamic
side sociology may be considered a sort of philosophy of history; at
least it attempts to give a scientific theory which will explain the
social changes which history describes concretely.

(C) Relations to Economics. Economics is that special social science
which deals with the wealth-getting and wealth-using activities of man.
In other words, it is concerned with the commercial and industrial
activities of man. As has already been implied, economics must be
considered one of the most important of the special social sciences, if
not the most important. Yet it is evident that the wealth-getting and
wealth-using activities of man are strictly an outgrowth of his social
life, and that economics as a science of human industry must rest upon
