DISPLACEMENT 



Again, the same manifestation of force (elec- 

 tricity, for instance) acting upon two different 

 kinds of matter, produces entirely different changes 

 in them. The carbon pencil will give off light, and 

 the electro-magnet will pull a load by the same 

 electricity. 



Therefore, it is apparent that different kinds of 

 material have the power to exhibit the same uni- 

 versal force, which passes from one material to 

 another material in their own peculiar way, but 

 that force is not inherent in any kind of matter.* 



PBOPOSITION XIII. - 



No material substance can produce force, nor can 

 any material substance absorb it or destroy it. 



Force cannot be stored up in any material, nor 

 in any way be augmented or decreased. 



Let a gun be loaded and fired. There will be a 

 violent change of some material close by. 



The force was not inherent in the gunpowder. 

 Neither has it been transmitted to the gunpowder 

 on a previous occasion and stored up, for then force 

 would have been changed into material substance, 

 and force is not a material substance. (Def. 2.) 



* NOTE. This proposition must necessarily be a Dogma. 

 All the reasoning this side of the Divide will not eradicate 

 the fetish notion. The world will ever remain flat, and the 

 sun will turn around it, and attraction will be inherent in 

 the magnet, and the rabbit 's foot will bring luck, ten thou- 

 sand years after the discovery of America.
