THE INDIRECT JUSTIFICATION OF ENTELECHY 213 



" the same " and " also/' which lie at the very root of 

 philosophy, in spite of their everyday character ; it is 

 enough for us here that acoustics forms the most simple 

 bridge from quality to motion in constellation ; from sound 

 to heat is but a step. 



We repeat that the kinds of motion " corresponding " to 

 heat (in general words molecules, atoms, and electrons) 

 are in their epistemological character as " real " as are the 

 moving particles of air corresponding to sounds. Or better : 

 all of them are either " non-real " or " real," as you choose ; 

 certainly they are of the same degree as to " reality," 

 the word reality being taken in the sense of " possibility 

 of perception." Hypotheses come in here, of course, as to the 

 specificity of what is not yet actually perceived ; but that 

 there must be a " something," with regard to discontinuity, 

 which is of the degree of the molecule or the atom or the 

 electron, is not an hypothesis but an assumption immedi- 

 ately suggested by certain facts. 2 



The best reason, finally, which forces us to make the 

 subject of science proper not " sound J: and " heat," but the 

 movement of a something, as soon as there is any evidence 

 that there is " also * movement where there is sound and 

 heat, is epistemologically given, as we know, in the possibility

2 If molecules or atoms were ever " discovered " perhaps by the aid of an 

 " ultramicroscope " what would be immediately perceived would be sensa- 

 tions, though on account of the length of the waves of light not sensations 

 representing the molecules or atoms directly. But would therefore the molecules 

 or atoms be "red " or "green," or at least " dark " or " light " ? By no means, 

 but discontinuities with, regard to sensations would compel us to say that here 

 we have a field for applying certain concepts which are waiting for application 

 in our mind. As concepts atoms would b e points from which fields of force 

 are radiating. All this is not metaphysics Inir. analysis of " enlarged Given- 



ness."
