MECHANISM OF NATURE 



the difference between tangible and intangible ma- 

 terial. The acceleration of the outlying atoms in 

 their life process must be far more intense than it 

 is in heat or electricity, and when heat and elec- 

 tricity are intense enough they will always produce 

 light. And in its intensity light will directly cause 

 a movement in Primary Spheres that intervene be- 

 tween organized bodies; it will not require the 

 presence of atoms to conduct it along. Light is 

 then more particularly a movement of void matter. 

 But whenever that movement encounters organ- 

 ized identities it must then enter into the life 

 process of that identity, and modify and be modi- 

 fied by that process. The light cannot as light pass 

 along the optic nerve, neither can it penetrate 

 transparent bodies as an uninterrupted displace- 

 ment of P. S. in plane layers. From this encounter 

 with organized bodies must spring the wherefore of 

 spectral analysis and all the different effects of 

 light. 



PROPOSITION XXV. 



There is one universal material. There is one uni- 

 versal force, the displacement of material 

 parts. There is One Identical, Primary, In- 

 comprehensible and Everpresent Cause, of all 

 Identity, of material Form or manifested 

 Force. 



There is something that is real, that is not the 

 creation of our imagination. Conscious reason per- 

 ceives space-filling material by perceiving innum-
