PROLETARIAN SCIENCE 



bourgeois scientists conveniently overlook the rev- 

 olutionary suggestions which come from their 

 tacit combination of sociology and biology. 



The proletarian scientist, on the other hand, 

 recognizes the vital connection between econom- 

 ic and biological facts. He understands that 

 the very consciousness of his own class interests, 

 and of the historical mission of the proletariat, 

 is not only a sociological, but also a biological 

 problem, and that his proletarian environment 

 molds his physical qualities and brain processes 

 differently from those of a prosperous and well- 

 fed bourgeois living in a beautiful home and 

 standing aloof from the uncouth impressions of a 

 slum environment. 



It is important to emphasize this, because at- 

 tempts have been made by certain bourgeois 

 scientists to justify the existence of different 

 economic classes, and the rule of privileged mas- 

 ters, on the ground of biological evolution. But 

 the formation of economic classes is not a biolog- 

 ical necessity. It results originally from economic 

 changes. The economic advantages then produce 

 biological advantages, and the interaction of these 

 movements then continues to favor the economi- 

 cally ruling class, up to the time when excessive 

 wealth leads to the atrophy of essential organs
