So far, we have kept pretty strictly within the field of "individual psychology" and "individual values." But we shall find, when we come to the field of the social values, that essentially the same laws hold. On the _functional_ side, the analogy between the individual mind and the social mind is a very close one, and the correspondences on the _structural_ side are numerous also. While we shall not try to find analogies in the social field for all these laws of individual value, it is not because of any difficulty that the problem presents, but rather, because it is unnecessary for the vindication of our thesis to do so.

[122] I am indebted to Professor John Dewey for many valuable suggestions and criticisms in connection with this part of my study. My more general obligations to him will be manifest to any one who is familiar with his epoch-marking point of view. Economic, sociological and political philosophy have, in my judgment, more to learn from him than from any other contemporary philosopher. [123] Pp. 141-42.
