realization of ambition, and affection has a tre- 

 mendous influence upon the conditions that sustain or 

 destroy life. 



As we have seen, emotion is the physiological 

 preparation of the entire organism for the production 

 of one or another of the great primary motor acts of 

 running, fighting or procreation. In the consequent 

 activation there are thrown into the blood stream large 

 amounts of internal activating secretions and gly- 

 cogen, intended for consumption in the muscles in the 

 production of motion. In addition to this "stoking 

 up" of the blood stream, there is a specific stimula- 

 tion or inhibition of every organ and tissue in the 

 body, in accordance with the r61e each is to play in 

 the intended adaptive muscular response. Blood is 

 transferred from the parts non-essential to muscular 

 action the stomach, intestines and genital system - 

 and concentrated upon the machinery necessary to 

 muscular action the heart, lungs, central nervous 

 system and skeletal muscles. The circulation is accel- 

 erated, metabolism is increased ; the production of 

 waste by-products is at its maximum ; the breath 

 comes faster; the heart beats quickly; the skin is 

 moist from excessive perspiration ; the limbs tremble ; 

 the extremities tingle ; every detail of the intended 

 muscular action is simulated. 



In man's early environment there was no break 

 between this preparation for muscular action and its 

 consummation. As a consequence, there was much 

 action and little restraint of action emotion just 

 as, to-day, when action ensues precipitately upon a 

 stimulus, there is no manifestation of fear, anger or
