same way, they plainly act under the guidance of 

 instinct ; for intelligence acts in no such fixed direc- 

 tions. 



Among these higher tribes, then, we find all 

 that is needed for the animal's good, for the indivi- 

 dual or for the species. In the youngest, it is suffi- 

 cient for its wants, because it is supplemented by 

 the instinct of the parent. It is simply more varied 

 in these higher tribes because their relations to the 

 world are more varied. And if, in some animals, 

 we recognise intelligence, we always find it subor- 

 dinate to instinct, so as to work in the same line 

 for the animal's good ; so that instinct, and not 

 intelligence, controls the animal. In every kind, 

 from the highest to the lowest, we find the thinking 

 being just high enough in its mental powers to 

 inhabit the body in which it is placed, with mind 

 enough to use that body. Mind and body are both 

 fitted to each other, and both work together in per- 

 fect relation to the world. They are parts of one 

 comprehensive plan, perfect in its conception and 

 execution ; a plan that commends itself to the wis- 

 dom of man, so far as he can comprehend it, but 

 higher, vaster, and more perfect than he could him- 

 self devise.
