BIOLOGY AND SOCIOLOGY 



* Come out into the light of things ; 

 Let Nature be your teacher.' 



— W. Wordsworth. 



' In matterf that really interest him, man cannot support the 

 suspense of judgment which science so often has to enjoin. He 

 is too anxious to feel certain to have time to know. So that we 

 see of the sciences, mathematics appearing first, then astronomy, 

 then physics, then chemistry, then biology, then psychology, then 

 sociology — but always the new field was grudged to the new 

 method, and we still have the denial to sociology of the name of 

 science.' — W. Trotter, Instincts of the Herd in Peace and fVar.
