CRUX OF THE EARLY EVOLUTIONISTS. 39 



thized with by those who recognize that if habit be 

 admitted as the key to the fact at all, the unconscious 

 manner in which the habit comes to be repeated is only 

 of a piece with all our other observations concerning 

 habit. For the fuller development of the foregoing, 

 I must refer the reader to my work 'Life and 

 Habit/ 



The purposiveness, which even Dr. Darwin, and 

 Lamarck still less, seem never to have quite recognized 

 in spite of their having insisted so much on what 

 amounts to the same thing, now comes into full view. 

 It is seen that the organs external to the body, and those 

 internal to it are, the second as much as the first, things 

 which we have made for our own convenience, and 

 with a prevision that we shall have need of them ; the 

 main difference between the manufacture of these two 

 classes of organs being, that we have made the one kind 

 so often that we can no longer follow the processes 

 whereby we make them, while the others are new things 

 which we must make introspectively or not at all, and 

 which are not yet so incorporate with our vitality as 

 that we should think they grow instead of being manu- 

 factured. The manufacture of the tool, and the manu- 

 facture of the living organ prove therefore to be but 

 two species of the same genus, which, though widely 

 differentiated, have descended as it were from one 

 common filament of desire and inventive faculty. The 

 greater or less complexity of the organs goes for very 

 little. It is only a question of the amount of intelligence 

 and voluntary self-adaptation which we must admit, and 

 this must be settled rather by an appeal to what we find
