The original plan of this paper included a general survey and critique of the leading tendencies in the study of politics during the last thirty or forty years. It was intended to compare the methods and results of the various types of political thought—to pass in review the historical school, the juridical school, the students of comparative government, the philosophers as such, the attitude of the economist, the contributions made by the geographer and the ethnologist, the work of the statisticians, and finally to deal with the psychological, the sociological, the biological interpretations of the political process.

It would have been an interesting and perhaps a useful task to compare the scope and method of such thinkers as Jellinek, Gierke, Duguit, Dicey and Pound; the philosophies of Sorel and Dewey, of Ritchie and Russell, of Nietzsche and Tolstoi; to review the methods of Durkheim and Simmel, of Ward and Giddings and Small; of Cooley and Ross; and to discuss the developments seen in the writings of Wallas and Cole.

It would have been useful possibly to extend the analysis to the outstanding features of the environment in which these ideas have flourished, and to their numerous and intimate relations and interrelations.
