THE MESSAGE AND PROMISES TO MANKIND. 247 



criminals, the imbeciles, the vicious, the diseased by in- 

 heritance to multiply their kind instead of the better 

 specimens, a race with superior brains, healthy frames, 

 and moral dispositions fully adapted to their environ- 

 ment, will inevitably in time be evolved; a race from 

 which the weak and worthless and wicked will have 

 been slowly but surely eliminated, and in which, thanks 

 to the beneficent laws of heredity, they can no more 

 re-appear to deteriorate the high type attained.*
