354 HEREDITY AND ENVIRONMENT 



immaturity in the human race greatly in- 

 creases the importance of environment and 

 training as factors of development. 



The possible training of human faculties is 

 also more varied and extensive than in other 

 animals, not only because those faculties are 

 more nvmierous but also because they are 

 more plastic and are capable of higher de- 

 velopment, that is, are more educable. Hu- 

 man faculties are functions and methods of 

 reaction, which are dependent in part upon the 

 bodily mechanism and in part upon environ- 

 ment and training. Habits are the usual 

 methods of responding to stimuli, and they 

 may be classified as inherent or acquired. The 

 latter are in a sense forced upon organ- 

 isms by environmental conditions. All educa- 

 tion is habit formation, and good education 

 like good environment is such an experience as 

 leads to the formation of good bodily, intel- 

 lectual, social and moral habits; it consists in 

 placing the individual in such an environment 

 and bringing such stimuli to bear upon him as 

 to call forth desirable responses and to sup- 

 press undesirable ones.
