82 PRODUCTION OF NATIONALITY

 nection between mind and body is extraordinarily 

 evasive. We must regard serious crime, I suppose, 

 as an abnormaHty, The results have recently been

 two years' imprisonment, were in all respects a 

 normal sample of the population differentiated only 

 by the circumstance that they were convicted

 than inborn disposition that is at work. 



I do not believe that in the present state of know-
