HUMAN LIFE 



gone so far above the lower animals in 

 his evolutionary progress, has become so 

 sublimated a kind of animal, reveals 

 such mysterious special powers and attri 

 butes, that we must be very careful not to 

 imagine that we can understand his life 

 on the sole basis of ever so exhaustive a 

 knowledge of the life of the lower animals. 

 But the mysteries in his make-up need 

 not lead us to mysticism in our attempts 

 at their explanation. We would much 

 better be agnostic than mystic. At least 

 that is the position which the biologist 

 student of human life must take if he is to 

 stand consistently in line with his scien 

 tific training and experience. 



We may assume, then, that we have 

 adopted, in our present quest for knowl 

 edge and understanding of human life, a 

 certain attitude, scientific, but open- 

 minded and not bigoted, and gained a 

 certain general orientation. With this 

 clearing of the atmosphere we are ready 

 to move forward in our quest. Too often 

 we make our start in studying human life
