210 CELL INTELLIGENCE THE CAUSE OF EVOLUTION 



from it; and secondly, by observing the actions of others. 



From late investigations, it has become clear that the 

 mind of man is the result of the minds of the individual 

 cells working together in his head, which we call in the 

 aggregate, his brain. 



The real thinkers are the brain cells. They are there 

 for that special purpose. The minds of men are not all 

 alike because they have not all received the same informa- 

 tion from the outside world. The cells of the brain can 

 only act on such information as they get from the outside 

 world. If they are told for a number of years that the 

 Catholic religion is the best it will take considerable proof 

 to change them to Mohammedans, and just as difficult 

 will it be to change a Mohammedan into a Catholic. 



Some one has said that the greatest thing in the world 

 is mind. It is true the mind in man has done all those 

 things that' man has produced, such as building railroads, 

 and other industries of commerce, literature, art, science, 

 social institutions and government. We can say further 

 that the mind of the cell has produced all those wonderful 

 structures we call plants and animals. 



The mind has been generally considered from two 

 points of view, as thought and conduct, that is to say, first 

 as receiving information and learning, and then as acting, 

 willing or doing. I think it would be more correct to di- 

 vide it into three departments ; first, the receiving of infor- 

 mation from the outside world, such as is performed by 

 the senses; second, the consideration of such information, 

 such as the work of the purely thinking cells of the brain ; 

 third, the willing and doing department or motor brain 

 cells, or motor system, which commands and directs the 

 actions. 



Now in order that the thinkers may be able to act on 

 any information received, they must of course be able to
