RESPONSE TO EXTERNAL STIMULI'S. 51 



Hut the effect of environment is not direct. Else 

 would affect all creatures alike. Environment can 

 only affect the individual as it stimulates, limits, or 

 diminishes its functional activity. Similarly medicine 

 accomplishes nothing, except through effect on func- 

 tional activity. 



Superiority of man to environment.

 men that stood alone." Lowell.
