280 THE AMERICAN JOURNAL OF SOCIOLOGY

chapter contains a classification of social facts under the general rubrics : (i) the state, (2) the moral powers, (3) economic facts, (4) family and education, (5) social pathology.

Our readers will not be likely to find this classification very per- suasive, and it is doubtful if the author's argument would remove the objections. It would be possible to apply much of his method regard- less of the theory of social classification. For this reason it would be worth while for sociologists to weigh well the fourth chapter. It is practically a program for the study of social psychology.
