CHAPTER XII 

 THE INNER ORGANS OF EXPRESSION 



ACQUIRED characters have no natural or- 

 gans of expression. They become effective 

 through emotions that arouse motor mechan- 

 isms created for other ends. These acquired 

 characters, failing natural expression, when 

 viewed from a social standpoint, are morality, 

 tradition, habit, and imitation ; from a psy- 

 chological standpoint they are associations 

 or, more technically, associations of ideas. 

 Starting from their economic antecedents, 

 they are due to deficits that save energy by 

 forcing economies. Surpluses forge structures 

 through which the resulting ideas find their 

 own means of exit, and, if they appropriate 

 any of the existing structures as means of 

 exit, they thereby destroy some traditions or 

 imitations in the social world and some asso- 

 ciations in the psychic field.
