THE STARTING POINT 



chart from some lighthouse, cape, or other prom- 

 inent and well-known point, the exact latitude 

 and longitude of which are known. We, too, are 

 setting out on a voyage into the open sea, the sea 

 of unknown ideas. Where is the first point from 

 which we can take our departure? 



Man is body, mind and soul, so we are told 

 by those who claim to have received this revela- 

 tion direct by wireless message from the un- 

 known. But if we are trying to locate the exact 

 bearings of either mind or soul, we soon dis- 

 cover that the experts disagree about the latitude 

 and longitude of these two points. However it 

 is generally admitted that the brain, the organ 

 of the intellect, is their headquarters. 



The human brain, then, is our point of depar- 

 ture. It is tangible and its location is fixed. 

 About its internal processes, we need not trouble 

 ourselves for the present, any more than the 

 navigator requires a knowledge of the internal 

 nature of the lighthouse from which he marks 

 his first course. The brain and its location are 

 definitely known quantities, definite enough to 

 make good points of departure for our inquiry. 



We know that this brain is a part of man's 

 anatomy. It has for its immediate environment 

 all the other parts of the body. It is, for instance,
