LIFE AND MIND 



somewhat higher, we find, along with this sim- 

 ple correspondence maintained by the whole 

 organism, a number of more complex, indirect, 

 and special correspondences, for the establish- 

 ment and maintenance of which there is differ- 

 entiated a particular relational structure. As the 

 correspondence increases in complexity, in in- 

 directness, and in speciality, the maintenance 

 of it is confined more and more to this spe- 

 cialized nervo - muscular structure — and the 

 enormously heterogeneous series of adjustments 

 which eventually goes on becomes distinguished 

 from the relatively homogeneous series of ad- 

 justments which has all along been going on, 

 as psychical life in contrast with physical life. 

 Thus by a regular process of evolution it hap- 

 pens that, while at the outset the psychical life 

 is but a slight extension of the correspondence 

 which constitutes the physical life, at the end 

 the correspondence which constitutes the psy- 

 chical life is all in all, and the processes of 

 physical life come to be regarded as entirely 

 subordinate to the maintenance of this higher 

 correspondence. 



Let us now briefly trace the various exten- 

 sions and complications of the correspondence 

 as it becomes more heterogeneous, definite, and 

 coherent. Scanty justice can here be done to 

 the subject, since it is necessary for me to com- 

 press into half a dozen pages the substance of
