THE MIND OF APES AND OF MAN 269 



of " instinct," such as that which causes it to find its 

 mother's nipple and to suck it, and to cling and support 

 its own weight as no full-grown child can do. It is 

 singularly free from any large number of inherited 

 " instincts," and, to its own great advantage, has, during 

 the many years in which it is protected by its parents, 

 to learn everything and to construct new brain 

 mechanisms — the results of " education " of the individual. 

 We here use the word " education " in its proper and 

 widest sense. 



Thus we get an indication of " the reason why " the 



modern rhinoceros has a brain eight times as big as the 



titanotherium's. It is more " educable." The ancestors 



of our modern armour-plated friend have been surviving 



and beating their less " educable " brothers and sisters 



and cousins through a vast geological lapse of time ; and 



I the brains of the survivors have always been bigger, and 



il they have become more educable and more educated 



J until the race has culminated in those models of " sweet 



l\ reasonableness," the modern rhinoceroses ! It must be 



)| confessed that this character attributed to the rhinoceros 



M is a matter of inference and not of direct observation of 



i\ that animal when under his native sky. We do not 



•! judge the survivor of a fine early Miocene family by the 



fury and annoyance he shows when shot at, nor by the 



stolid contempt with which he treats mankind at the 



Zoo. The same signification — " educability " — attaches 



to the large brain of the higher apes ; and man's still 



larger brain means still greater educability and resulting 



reasonableness. 



In order that natural selection and the survival of 

 the fittest should have led to this increased size and 

 accompanying educability of the brain, it is necessary to
