(4) Mind and Body. The problem of the relation of mind and 
matter, from this standpoint, becomes chiefly a question of the logic of 
scientific method. The present writer has elsewhere (PAzlosophical 
Review, May, 1903) suggested, that this is the consistent interpretation 
of Professor BALDWIN’s chapter, in the book before us, on ‘‘Mind and 
Body.” The psychical ceases to be an entity in any sense of the term, 
even in the sense of energy. Instead of the psychical being subor- 
dinated to the concept of energy, as Professor OstwaLp contends, or 
being regarded as interchangeable because universally parallel, as Pro- 
fessor BALDWIN contends, these concepts must, in time, be recon- 
structed in terms of each other, and take their place in a scientifically 
continuous series, the terminology of which remains to be worked out, 
but of which it is the great distinction of Professor BALDWIN to have 
given a hint in his otherwise paradoxical doctrine of psychophysical 
evolution. Another hint in the same direction is the recent attempt to 
define the meaning of the psychical by Professor GEorcE H. Mean, 
in the University of Chicago Decennial Publications, Volume III, 
where the psychical is defined as the process, as contrasted with the 
content, of the experience, or, to use the terms of logic which he 
employs, the psychical is identified with the copula of the judgment.

The Psychology of Action.' 
We have in this book what we have learned always to expect from 
the pen of its distinguished author, a lucid, interesting and original 
presentation of the principles of psychology. Its originality consists 
in the successful employment of terms chosen from the sphere of 
practical life, as the leading categories and principles of division. In- 
stead of the traditional classification of the subject-matter under the 
rubrics of cognitive, affective, and conative states, we have the re- 
freshing consciousness of feeling that we follow the meaning of the 
author from the beginning without being involved in a system of tech- 
nicalities. He discusses mental life under the headings of Sensitive- 
ness, Docility, and Initiative. These terms retain the content which 
they have in ordinary life while at the same time serving the purposes
