Habit and Instinct. 



their origin in habit, though they may now be more or 

 less definitely instinctive. It would seem, however, that if 

 natural selection be accepted as a potent factor in organic 

 evolution, and unless good cases can be brought forward 

 in which natural selection is necessarily excluded and yet 

 habit has become instinctive, we may, in face of the bio- 

 logical difficulties which render direct transmission more 

 and more hard to accept, adopt some such view as the 

 foregoing, and, while still believing that there is some 

 connection between habit and instinct, admit that the con- 

 nection is indirect and permissive rather than direct and 

 transmissive.
