game, or they have organized work that would bring them food ; 

 that is another way. Even at the table you can see hunger 

 driving some people into one kind of behavior and others into a 

 different kind. These examples of the different ways in which 

 hungry people may behave show different kinds of emotion 

 habits as well as of action habits. In fact, our whole manner of 

 living represents ascheme of habits in which emotions, thoughts, 

 and actions are all parts of a unity. One who shows what we 

 call breeding or good manners at table has a different set of 

 feelings from one who shows bad manners. Both may be 

 equally hungry. The difference in behavior represents differ- 

 ence in habits— feeling and thinking habits as well as action 

 habits. 



213. The formation of habits. If a baby is accustomed to 

 feel the joy of satisfied hunger immediately after hearing a 

 certain sound, he will soon come to have that joyous feeling on 

 hearing the sound. If people discover that controlled anger 

 brings more satisfaction than uncontrolled anger, they will in 

 time find a way to control anger. 



The habits that we acquire all involve feeling as well as think- 

 ing and doing. The nerves, reaching all parts of the body, are 

 sensitive to changes and in turn bring about changes. The 

 blood reaches all over the body: slight changes in any set of 

 organs alter the chemical condition of the blood ; slight changes 

 in the chemical condition of the blood bring about important 

 changes in the activity of protoplasm in all parts of the body. 

 In this way emotions influence our thinking, our actions, and 

 the behavior of the internal organs. On the other hand, both 

 our thinking and our exercise of the skeletal muscles can modify 

 our emotions.
