In spite of the remarkable development which this century has witnessed in the science of psychology from the time of Fechner to the present, most psychologists will admit that the science has as yet contributed little to the development of the social sciences, to the solution of the problems of societary life. A beginning, it is true, has been made in some of the social sciences in applying psychological principles to the solution of their problems. This is the case, for example, in political economy, especially in the attempt which the Austrian school has made to build up a theory of value upon principles furnished by the older individual psychology. But the contributions which psychology has thus far made to social science have been, with a few exceptions, small and insignificant compared with what has been expected from it.
The reasons for this failure of psychology to contribute materially to the solution of social problems have been many. One has already been suggested in the preceding article of this series, namely, the dominance of the individualistic method and point of view in psychological investigation. Another is to be found, perhaps, in the failure to develop a comparative or genetic psychology. The reason, however, which appears to us fundamental and inclusive of the others is that psychology has not been developed from the point of view of function or life-process. A mere structural[2] psychology of the adult human individual cannot, from its very nature, give an interpretation of life in its broadest phases, much less of the activities of society.
