THE CEREBRUM 141 



with Miinsterberg 1 that one must alternate between two 

 views without seeking to reconcile them ; as an investigator 

 one must look for material causes, but for the sake of 

 moral power and conviction one must hold fast the belief 

 in free agency, which has always commended itself to 

 the men who have done most for the world. 



Another assertion of Miinsterberg may be quoted at 

 this point. Many writers constantly refer to the "sub- 

 conscious mind" in their discussions of brain activity. 

 Is it not better, asks the psychologist, to reserve the 

 word "mind" for that which is conscious? Physiologists 

 will certainly agree to this; most of the action of the ner- 

 vous system is subconscious, but nothing would seem to 

 be gained by calling such action mental.
