THE INDIRECT JUSTIFICATION OF ENTELECHY 265 



demonstrate the legitimacy of our factor itself as a part 

 of the aprioristic system of natural factors or entities. 

 We have to show that epistemology entitles us positively 

 to introduce into science such a something as entelechy 

 is. In other words, we have to establish vitalism from 

 what may be called the organisation of the Ego. 



That will be done, and the following pages will prepare 

 the way for it. 



All the proofs of vitalism given in our merely scientific 

 section were indirect proofs, or proofs per exclusionem ; all 

 the possibilities but one were wrong, and therefore that 

 one possibility was true. 



Our next endeavour will be to prove vitalism directly. 

 And upon this direct proof the positive epistemology of 

 entelechy will afterwards be founded.
