We are constrained to believe that the morphological conclusions

Diseases of Personality.^ 



Among the numerous interesting monographs produced by M. 

 Ribot, none has a more practical interest than the present volume, 

 which is issued in authorized translation and in a neat and convenient 

 form. 



The book is already too familiar to require an extended notice 

 here. It may be noticed in passing that the author, perhaps reflect- 

 ing the influence to Maine de Bivan, never wholly falls into the error 

 which is so glaring in the modern physiological psychology, of regard- 

 ing consciousness as a mere epiphenomenon — a shadow which is cast 

 by neuroses, but unavailing as a determinant of subsequent psychoses. 

 Although there are many passages which ignore the great, even domi- 

 nant effect of consciousness upon the psychical life, yet the author is 

 sufficiently explicit in abrogating the view. 



" It is probable that consciousness has been produced like any 

 other vital manifestation, at first in a rudimentary form, and appar- 

 ently without great efficacy. But from the moment it was able to 

 leave behind a vestige, to constitute in the animal a memory for the 

 psychical sense, utilizing its past for the profits of the future, from 

 that moment a new chance of survival was created." 



This is the point of view, and carrying it out consistently, the 

 author elaborates a rich material in a way suggestive alike to physician 

 and psychologist.
