114 INSTINCT 



feel that it is the only appropriate and natural thing to 

 do. . . . And so, probably, does each animal feel about the 

 particular things it tends to do in the presence of particular 

 objects. ... To the lion it is the lioness which is made to 

 be loved; to the bear, the she-bear. To the broody hen the 

 notion would probably seem preposterous that there should 

 be a creature in the world to whom a nestful of eggs was not 

 the utterly fascinating and precious, never-to-be-too-much- 

 sat-upon-object which it is to her." 



With increasing intelligence attention becomes devoted 

 to things which are more remotely connected with instinctive 

 interests, but even in ourselves instinct, in one form or 

 another, supplies the basis of most of our springs of action. 

 With us, as with the lower animals, self-preservation and 

 the perpetuation of the stock afford, broadly interpreted, 

 the main business of life.
