ABSTRACT
In the political world, the dictum, "the greatest good of the greatest number", stands for an effort to make measurements. Statistics of social facts as we ordinarily get them are, of course, measurements. The measurements of experimental psychology are not such measurements as we need. They are measurements of activity looked upon as within the physical individual. This chapter confines ourselves to the groups that appear in politics, and as they appear in politics. It gets all the ideas and policies and selfishnesses that enter into current talk or specialized political talk stated in the same way, as differentiated activity, as the reflection of lower-lying activity. The chapter finds that the political interests and activities of any given group—and there are no political phenomena except group phenomena—are directed against other activities of men, who appear in other groups, political or other.
