THE BIOLOGICAL BASIS OF SOCIOLOGY 



of the just social order, it is not true that human nature cannot change, 

 as our social inheritance develops; it is not true that human beings 

 do not need more than fifty calories a day, or so many milligrams 

 of such and such a vitamin; it is not true that psycho-analysis throws 

 no light on human behaviour. The sciences of the sub-social organisa- 

 tional level state, in fact, the laws applicable to human organisms as 

 animal organisms. But by virtue both of their humanity, and of the 

 fact that they congregate together in supra-human organismic groups, 

 they constitute a higher level of experience, for which the laws of the 

 lower level alone will not suffice. The sociologist must cope with the 

 greater complexity on its own ground. To treat sociological problems 

 with purely biological concepts is to add oneself to the long list of 

 humanity's false prophets.
