PREFACE 



According to popular standards of civilized 

 peoples, men of one's own race and tongue were 

 called "men," "warriors," "heroes," but people 

 of other races were "barbarians," "unholy ones," 

 "foreign devils." The founder of one's own clan 

 was often considered to be the son of a deity, while 

 the barbarians were the descendants of monkeys 

 or other wild animals. Or the first man was 

 created perfect, in the image of God. One's own 

 family, of course, was fairly true to type but sin 

 had played havoc with the features of other races. 

 To believe all this was comforting to one's own 

 "face" in a world where the inferiority complex 

 occasionally haunted even kings. 



Imagine then the effect of telling one-hundred- 

 percent Americans that they are not the descen- 

 dants of the god-like Adam but are sons and 

 daughters of Dryopithecus, or of some nearly allied 



genus of anthropoid apes that lived in the Miocene
