FORCING INTELLIGENCE 89 



purpose as the human fingers and thumbs, because 

 of the isolation of the protruding fibres and the dis- 

 tance between them. 



It appears then, that man alone has specialized, in 

 his finger tips and thumbs, a highly developed, acute 

 sense of touch, adapted to distinguish a wide range 

 of sensations, indicating many and various properties 

 and powers possessed by the objects in his environ- 

 ment; knowledge of which must forever remain 

 inaccessible to the rest of the living world. This 

 unique power possessed by man, obviously has great 

 survival value, which differs in individuals accord- 

 ing to the degree of the general intelligence possessed 

 by them. Here, then, the third and greatest of the 

 agencies which forced the growth of human intelli- 

 gence has been discovered. 



Thus the emergence of an ever higher intelligence 

 has been forced, in the human race, by the converg- 

 ence of three separate agencies, viz., the erect body, 

 the exceptionally complex organism on which the 

 possibility of the erect body depends, and the highly 

 specialized sense of touch which is impossible with- 

 out the erect body, and, therefore, a unique feature 

 peculiar to the human race. For this reason has it 

 been impossible in the past, and seems impossible 

 for all future, that any living creature of any past 

 or present type could ever develop an intelligence 

 comparable in extent or quality to that possessed 

 by average humanity since the dawn of history; 

 but many thousand generations before that dawn
