PROPOSITION XXI. 



The change of void matter into organized matter, 

 and the necessary simultaneous change of organ- 

 ized matter into void matter through the resultant 

 surplus of space in one, and the resultant want of 

 space in the other, constitute that inequality which 

 is necessary to bring forth changes in matter, or a 

 display of force. 



Can a cause be greater than that which was 

 moved by it? Can anything be less than another 

 thing, when both are inseparable parts of one 

 whole? In the infinite circle of cause and effect, 

 and subsequent cause which was the result of the 

 former effect, can there be first and last or great 

 or small? It is but the whole which is great, and 

 the smallest part still represents that whole ring 

 of cause joined inseparably on cause coming from 

 the infinite and going to the infinite. "The wind 

 blows and we hear the sound thereof, but we know 

 not whence it cometh and whither it goeth. ' ' 



The observation of the changes wrought in mat- 

 ter by force, and of the manner in which these 

 changes are made, that includes the whole field of 

 human reasoning; beyond that lies the infinite.
