group which reared and nurtured them is but part of a 

 wider society. A wealth of race experience is acquired 

 along with an increasingly secure economic basis for both 

 individual and social life. Production, local exchange of 

 wares, and extensive commercial relations are developed.

 freedom from dangerous famines is the lot of larger 

 and larger numbers of mankind. With a more plastic 

 and flexible structure of social relations, founded upon 

 a substantial and extensive economy, the plane of the 

 struggle for existence is, for most of mankind, once for 

 all raised above the level of the brute, and the increasing 

 dependence placed upon the intellectual and ethical ele- 

 ment assures a truer realization of justice, humanity 

 and happiness.
