Reduction 55 



end. The part may be dwarfed or it may 

 be enlarged, but it will at least be altered. 

 Emotion is thus a cause of bodily change, and 

 after each strong emotion, some organs being 

 reduced and others enlarged, the transitions 

 are made by which organisms pass from one 

 stage of their development to another. 



In lower organisms, the emotion and reduc- 

 tion due to the loss of an organ are often fol- 

 lowed by its regeneration, and the limb or 

 part is soon replaced. Apparently this does 

 not take place in higher organisms, but the 

 difference is only apparent. If we assume 

 that a reduction, by which the specialization 

 of the part is thrown off and the cells are 

 restored to their original undifferentiated state, 

 precedes the regeneration, it follows that this 

 reduction would not take place unless an 

 emotion or shock affects the part that is re- 

 generated. This would be true of lower or- 

 ganisms, for the parts are semi-independent 

 and the response to an injury is direct. But 

 in higher organisms the injury is in one part 

 and the emotion is in another. If a man 

 loses a ringer, the emotion is not in it, but
