HUMAN LIFE 



Now the biologists have a position 

 between these extremes. When they 

 talk about microbes and Dinosaurs their 

 statements are accepted at face value. 

 But when they talk about human beings, 

 which the biologist can study quite as 

 carefully as he can other kinds of beings, 

 there are reservations. When the biol- 

 ogists' talk about human beings is limited 

 to statements about lungs and liver, 

 skeleton and ductless glands, it is not 

 questioned. But when their talk is about 

 the behavior of human beings, about 

 their psychology, their heredity, their 

 responses to environment and education, 

 and their position in Nature, then their 

 talk is tested by the miscellaneous per- 

 sonal observations and prejudices and 

 desires and hopes and beliefs of each 

 individual, and it is accepted or not as it 

 confirms or contradicts each one's notions 

 derived from these things. We all, or 

 most of us, think we know human beings 

 as well as the biologist does. Most 

 assuredly the biologist does not know all
