228 BIOLOGY OF DEATH 



genetics was sufficiently ample and profound to make it 

 possible to make a racial germ-plasm exactly whatever 

 one pleased; what individual or group of individuals 

 could possibly be trusted to decide what it should be? 

 Doubtless many persons of uplifting tendencies would 

 promptly come forward prepared to undertake such a

 feel that man's instinctive wariness about experimental 

 interferences with his germ-plasm is in considerable 

 degree, well-founded. 



But because of the altogether more impersonal na- 

 ture of the case, most men individually and society in 

 general are perfectly willing to let anybody do anything 

 they like in the direction of modifying the environment in

 propaganda flourish like the proverbial bay tree. 



Of all organized activities looking towards the direct
