i ORGANIC AND INORGANIC 53 



Organic bodies are not simply moved. 

 They move themselves. They have 

 1 'self -mobility." 1 They are so consti- 

 tuted that even when an external force 

 acts as an excitement or a stimulus, the 

 organic forces which emerge and act are 

 much more complex and important so 

 much so that as compared with the 

 results produced by these organic forces 

 the direct results of the incident forces 

 are "quite obscured." 2 Mr. Spencer 

 even confesses that these two kinds of 

 action are so different in their own 

 nature that in strictness they " should 

 not be dealt with together." But he 

 adds that "the impossibility of separat- 

 ing them compels us to disregard the 

 distinction between them." This is a 

 most lame excuse for the careless and 

 a still worse excuse for the studied use
