344 SOCIAL HEREDITY AND SOCIAL EVOLUTION 



nature rather than nurture has been the predominant 

 force, in human social evolution nurture rather than 

 nature has stood foremost. It is not what we are 

 born, but what we become after birth that makes 

 us men : it is not the powers of babes, but what civili- 

 zation makes of those powers that constitutes the 

 essence of mankind. The future is full of hope.
