6. How ENTELECHY is AFFECTED 



We have discussed at full length how entelechy may 

 possibly act with regard to an energetical or a mechanical 

 inorganic system, or in other words, what it may change in 

 any way in such a system. But we have not even 

 mentioned so far the corresponding question : how may 

 changes in any inorganic system affect entelechy ? But 

 this problem, of course, needs at least to be mentioned 

 as well as the other. In the theory of so-called psycho- 

 physical interaction both problems, as a rule, are treated on 

 equal terms : the " Psychical ' is regarded not only as 

 affecting the " Physical," but also as being affected by it. 



a. THE PRINCIPLE OF ACTION AND REACTION AS 

 RELATED TO ENTELECHY 



In the first place we are, I think, obliged to inquire 

 whether in the work of entelechy there may occur anything 

 comparable with the Newtonian principle of action and 

 reaction, this principle, of course as in " electrodynamical 

 mechanics " being understood in the widest possible onto- 

 logical sense. Of course, since entelechy is neither an energy 

 nor any factor of the mechanical type, the principle of 



reaction cannot apply to it in any physico-chemical or
