Why We Behave 



Like Human Beings 



By George A. Dorsey, ph.d. ll.d. 



Formerly Curator of Anthropology, 

 Field Museum and Associate Professor 

 of Anthropology, University of Chicago 



John B. Watson, author of "Behavior- 

 ism" says: "It focuses for the first time 

 the light of science upon the weak and 

 shivering organic unit we call man. 

 Only a man who has spent his life 

 studying man in the jungle as well as 

 in the drawing rooms and cafes could 

 write such a book. S3.50.
