GENERAL CONSIDERATION. 329 



vinced his opponents, who are quite numerous, upon 

 this question. On the other hand, his followers 

 claim that he has shown the animal mind to be 

 essentially like that of man, and this is all that can 

 be expected. A majority of scientists would hold 

 this position. The question, therefore, resolves 

 itself into a simple one. Are the characteristic 

 qualities of the human mind, such as the power of 

 abstraction with its accompanying power of language, 

 the intuitions of causation, time, space, etc., and 

 its unique moral sense, are these qualities, with the 

 powers they provide, of such a nature that they 

 could have been developed from the mental quali- 

 ties of animals ? To this question each man must, 

 after careful consideration, give his own answer. 



A more general objection to the views of the 

 Darwinian school, than any of the above is, perhaps, 

 the most important of all. Even if it be granted 

 that a development such as supposed might have 

 taken place, no sufficient cause has been given for 

 the remarkable and rapid development of man. All 

 through the long geological ages this factor of intelli- 

 gence remained comparatively undeveloped. Some- 

 what of an advance there was. With the beginning 

 of the tertiary age, as we have seen, there was an 

 increase in the size of the brain. This increase, 

 however, in most cases, amounted to little. But in 

 man it was so great and so rapid that in a compara- 

 tively short time his brain became twice as large as 

 that of other animals. His intelligence became so 

 great that the difference between him and other 

 animals became prodigious, so great indeed, that,
