“The Caveman Within Us” seems to succeed in doing what it apparently set out to do, namely, to give an account of the principles of the new psychoanalytic psychology; to trace those principles in their various ramifications in the conduct of the individual both in his personal and social relationships and to make the whole account of connected, interesting discourse, free from technicalities. It is an appeal to the intelligence of the average reader, excellently well done. In fact, of the popular books that have dealt with various aspects of this subject, this one stands out, as have the author's previous writings, as an example of clarity of presentation. It is particularly worth while in its discussion of the various collective activities of mankind on the one hand and on the other in its discussion of the whole question from the evolutional, developmental, phylogenetic standpoint.
