An Examination of Society from the Standpoint of Evolution. By Louis WALLIS. Columbus, O.: The Argus Press. Pp. 325.
POPULAR education has produced a multitude of amateurs who have just enough rhetorical knack, commonplace information, and conceit of wisdom to afflict reviewers and the public with a flood of superfluous books. This evil is acute in the field of social science. It should not be surprising, therefore, that workers in this field are skeptical about the merits of a new publication, unless its author has an assured aca- demic position or previous scientific standing. The assumption is that it is merely another weariness to the spirit of specialists, always overtaxed in keeping up with the work of their colleagues who have something to say.

2. A second principal fact is that "the integration of society rests upon concomitant integration of capital," both material and intan- gible ( p. 51).
3. Social cleavage is one of the principal factors in the capitaliza- tion of social development (p. 51 ); *'. e. :
Cleavage actively enlisted the egoism of the upper class in the tremen- dous work of social development. A large part of the appropriated labor of the masses was converted into the material and spiritual tools whereby humanity conquers its environment and struggles upward along the path of progress By promoting the growth of capital, the upper class uncon-
