THE EVOLUTION OF MIND 



it follows that a lowly organized animal, in which 

 there is established a correspondence only with 

 the most general environing relations, and which 

 therefore has experience only of such most gen- 

 eral relations, has at the same time a uniform 

 experience which maintains a complete cohesion 

 among its simple psychical states. On the other 

 hand, a highly organized animal, in which there 

 are established correspondences with many com- 

 plex and special relations, will have a varied ex- 

 perience, and at the same time a varying cohe- 

 sion among its complex psychical states. While 

 the most general relations which it experiences 

 will also be the most frequent, and while sun- 

 dry special relations (as in the seizing of its prey 

 by the fly-catcher) will be extremely frequent, 

 there are many other special relations of which 

 the experience will be much less frequent. And 

 accordingly, along with the perfectly coherent 

 psychical states generated by the former, there 

 will be a congeries of less coherent psychical 

 states generated by the latter. Or, to restate the 

 case in physiological language : While in the 

 lower organism there will be a number of tran- 

 sit lines permanently established, and scarcely 

 any tendency toward the formation of new ones ; 

 on the other hand, in the higher organism, there 

 will be a number of permanent transit lines and 

 a number of such lines in process of formation, 

 along with a continual tendency toward the es-
