WHAT IS INTELLIGENCE? 197 



brain and spine, are, of course, the caretakers and gov- 

 ernors of the body. They govern the different organs, 

 attend to the circulation of the blood, regulate the heart, 

 take care of waste matter, direct the digestive organs, 

 liver and every other organ. 



The brain is the center of intelligence for the entire 

 body as a whole. The following is a good description of 

 a body or cell community, by Prof. Benjamin Moore, Pro- 

 fessor of Chemistry in the University of London : 



"The body of one of the higher animals or man con- 

 sists of an enormous assemblage or community of many 

 millions of millions of such living units far outnumbering 

 the total population of human individuals on the earth, 

 and this vast community of living cells which together 

 constitute a living man or woman, are, in a state of health, 

 so co-ordinated and regulated as to excel, in goodness of 

 government and co-adaptation to one another's wants, 

 any social system which has ever regulated a body corpor- 

 ate in human history. There is just as much division of 

 labor and mutual assistance and government as in a state 

 or vast empire, and moreover there are scarcely any of 

 the defects of a bad government in the affairs of men in a 

 social community which may not find their parallel in the 

 organic happenings in a single human body when invaded 

 by disease. Similar types of cell are aggregated into for- 

 mations called tissues, designed for serving some com- 

 mon office of the body, and at times two or three tissues 

 are blended together to form what is termed an organ for 

 carrying out some special task. The stomach may be 

 taken as an example of such an organ. Internally it pos- 

 sesses a layer in which are millions of cells formed into 

 little tube-like glands, which secrete a digestive fluid and 

 pour it out by millions of minute ducts or pores upon the 

 food contained in the cavity of the stomach.
