142 THE PROBLEM OF EVOLUTION 



This fact, according to Friedenthal, serves as a 

 proof, * that in man is something peculiar , which marks 

 him off from all other living creatures, and I agree 

 with the scientist Wasmann on this point which dis- 

 tinguishes man, as we know him, from all other living 

 beings' 



Speech is undoubtedly an important aid to

 can agree with these remarks.

 with religious conviction. Dr. Friedenthal, too,
