ing just a little further than other animals of 

 using connections of ideas as stepping-stones to 

 knowledge must have had the effect of causing 

 man to converse; and the use of language must 

 have given him wider range of thought, since it 

 placed all the experience and the knowledge of his 

 tribe at his service. 



We can see, then, how easily and rapidly he 

 would go ahead of all other animals in mental and 

 moral evolution, and how he would inevitably 

 acquire the habit of thinking more and more about 

 his own sensations, causing him to feel happy or 

 unhappy in circumstances which would scarcely 

 have affected the equanimity of his ancestors. He 

 would, in fact, cease to be an animal of impulses 

 and instincts, and become a conscious human 

 being. 



I think, therefore, that there is no need to dis- 

 believe that this difference exists between men and 

 other animals, merely because the dissecting-knife 

 reveals no important difference in their nervous 

 structure.
