MECHANISM OF NATURE 



where pushing on one another, and the movement 

 of one must affect the whole mass. But the move- 

 ment of any organized body must also affect the 

 whole Universe, because such movement compels 

 some other body to move, and finally the movement 

 of organized bodies must come again to a move- 

 ment of void matter. 



The atoms of organized bodies are built up of 

 primary spheres in closest possible contact; there- 

 fore, a primary sphere may not penetrate an 

 atom. And if an atom, or an aggregation of many 

 atoms in an organized body, change place any- 

 where in the Universe, several rows of primary 

 spheres of void matter must be moved out of 

 the way. 



But where shall the primary spheres move to in 

 a Universe that is full? 



There is no vacant place behind the moving 

 body, for something is pushing it. (Prop. II, B. 

 3.) If the moving body is not pushed out of its 

 place by another organized body, then it must be 

 by void matter. 



While we can observe the movement and pressure 

 of organized substances, even in the gaseous state, 

 through almost endless notations, these movements 

 sooner or later are converted into some so-called 

 force. That really means, "The movement of 

 bodies which we can directly observe is transferred 

 to a movement in void matter, where we cannot 

 directly observe movement.'' 



And because primary spheres are incompressible
