The Evolution of Human Intellect 293 



G. ? " " Because I planted my ten cents, and we will have lots of 

 ten cents growing." 



(3 yrs.) B. climbed up into a large express wagon, and would 

 not get out. I helped him out, and it was not a minute before 

 he was back in the wagon. I said, " B., how are you going to get 

 out of there now ? ' ! He replied, " I can stay here till it gets little, 

 and then I can get out my own self." 



(3 yrs.) F. is not allowed to go to the table to eat unless she 

 has her face and hands washed and her hair combed. The other 

 day she went to a lady visiting at her house and said, "Please 

 wash my face and hands and comb my hair ; I am very hungry." 



(3 yrs.) If C. is told not to touch a certain thing, that it will 

 bite him, he always asks if it has a mouth. The other day he 

 was examining a plant, to see if it had a mouth. He was told 

 not to break it, and he said, "Oh, it won't bite, because I can't 

 find any mouth." 



Nowhere in the animal kingdom do we find the psycho- 

 logical elements of reasoning save where there is a mental 

 life made up of the definite feelings which I have called 

 1 ideas,' but they spring up like magic as soon as we get in a 

 child a body of such ideas. If we have traced satisfactorily 

 the evolution of a life of ideas from the animal life of vague 

 sense-impressions and impulses, we may be reasonably sure 

 that no difficulty awaits us in following the life of ideas 

 in its course from the chaotic dream of early childhood to 

 the logical world-view of the adult scientist. 



In a very short time we have come a long way, from the 

 simple learning of the minnow or chick to the science and 

 logic of man. The general frame of mind which one acquires 

 from the study of animal behavior and of the mental de- 

 velopment of young children makes our hypothesis seem 

 vital and probable. If the facts did eventually corroborate 

 it, we should have an eminently simple genesis of human
