As a part of its work, the committee on research of the American Political Science Association has undertaken a survey of the relation of politics to kindred types of inquiry, including psychology, anthropology, geography, biology, engineering and others. The purpose of such an inquiry is to explore the relationships that exist with kindred sciences, to facilitate coöperation with our fellow-workers, to improve our methods of investigation, and to promote the progress of political science.
The committee is not responsible for this report, for its form or content, its scope or method, its sins of omission or commission. Probably the general sentiment of the committee toward psychology would be expressed by the phrase, con amore ma non troppo.
It may be worth while at the outset to scrutinize some of the earlier relations of psychology to political science, for the friendship is one of long standing. In the earlier forms of political thinking, there are crude types of psychology that are of great interest and significance in the development of the art of political thinking. These philosophers evidently utilized all of the psychology that was current in the construction of their political systems.
