252 GENETICS 



large extent with respect to incest, and the marriage 

 of persons as noticeably defective as idiots or those 

 afflicted with insanity, and also in America with re- 

 spect to miscegenation, but a cautious and intelligent 

 examination of the more obscure defective traits,

 to the romantic way of looking at things. Science 

 is simply "organized common sense," and romance, 

 that dispenses with this balance-wheel, although it 

 may be entertaining and always exciting at first, 

 is sure to be disappointing in the end. Marriages 

 may be "made in heaven," but, as a matter of fact, 

 children are born and have to be brought up on earth.

d. Segregation of Defectives 



Persons with hereditary defects, such as epileptics, 

 idiots, and certain criminals, who become wards of 

 the state, should be segregated so that their germ- 

 plasm may not escape to furnish additional burdens
