 shows. Even natural selection is not necessarily beneficial. 

 Many species, after having overcome the enmity of other 

 species and after having adjusted to the physical environ-

 most completely free of all struggle save that within his own 

 species. And he alone is gifted with the inventiveness to 

 make competition of man against man a thoroughly annihi- 

 lating struggle.
