ON MAN AND HIS DEVELOPMENT. 59 



and from this superiority of hand, the brain suggesting 

 the idea, he can make inventions, tools, implements, 

 weapons, complicated machines and appliances, to serve 

 his ends. Moreover, through the higher differentiation 

 of the larynx and tongue, he has the faculty of articulate 

 speech in a much higher degree than any of the other 

 animals, and he can thus communicate with his fellows 

 to an extent that is quite impossible to them. Some of 

 them, indeed, including his nearest relatives, possess the 

 faculty of speech in a low degree ; but man alone can 

 convert the vocal sounds which he can make in the 

 greatest variety, into signs of his inmost wishes and 

 thoughts, and into general conceptions, by means of 

 which he can think and reason about classes and uni- 

 versals, the highest prerogative of the scientific human 

 intellect. Above all, the mass of man's brain is larger, 

 its cells and fibres more numerous and complicated, and 

 he can thence make greater mental acquisitions, which 

 he can store away in the corpuscles of the brain, as in 

 safe and secret closets, for future use. He is, from this 

 comparatively greater size and finer structure of brain, 

 a being of " larger discourse, looking before and after." 

 He can think more clearly, he can see more deeply, he 

 can feel more finely and variously, than any of his 

 humbler brute brethren. He is presented with a clearer 

 and fairer picture of the universe than the dull and 

 confused apprehension of the brute can give. Moreover, 

 his nerves are more numerous and more delicately strung, 

 thereby giving him not only a wider area of pleasure 

 and pain, but special emotional delights, in the cultiva- 

 tion and expression of which man has become an artist, 

 as by his general brain superiority he had become an 

 inventor and a thinker. Finally, man is the pre-emi- 

 nently social animal, more essentially so than the bee,
