MECHANISM OF NATURE 



And since we can see, in a thousand ways of 

 every-day life, that all motion is the result of 

 inequality of things around us and ever present 

 force equalizing them, therefore, force cannot 

 be, etc. 



PROPOSITION XIX. 



All substances which we directly perceive are 

 built up of primary spheres, which we cannot di- 

 rectly perceive. 



Because matter is continuous throughout the Uni- 

 verse (Prop. I), and primary spheres of void mat- 

 ter penetrate all substances. (Prop. XV.) 



Therefore, all the primary spheres of void matter 

 in the Universe are in contact. 



Therefore, any two bodies, with the addition of 

 a Universe full of primary spheres, constitute a 

 solid ring, no part of which can move in relation 

 to any other part of the ring, unless there is in 

 the ring one part which may get longer at the same 

 time that another part is getting shorter. 



Because the primary spheres flow to us from the 

 sun and make changes on earth which we can per- 

 ceive; therefore, the primary spheres must on the 

 earth be built up into ponderable matter. (Com- 

 pare Prop. XIII, B. 3.) 



Then the sun which disorganizes may transmit 

 force to the earth, which organizes, for the two 

 bodies are unequal. (Prop. XVIII.) 



Therefore, etc.
