EXPLAINS NATURAL PHILOSOPHY 163 



is electric energy, from the sun the electric heart 

 of the solar system. Motion, I contend, is not" a 

 cause but an effect, and all physical motion is the 

 result of electric energy. And to say with Tindall, 

 that light and heat is a mode of motion is to 

 state an absurdity, for motion is the result of some 

 force operating on matter. It is not a cause but an 

 effect produced by a cause. 



I explain force and "the redistribution of matter 

 and force" as the product or the result of the uni- 

 versal laws of electric attraction and repulsion, which 

 control atoms, suns and worlds and all matter in 

 body and space. 



Mr. Spencer offers no explanations and relegates 

 all to the convenient dumping ground of the un- 

 knowable. What he calls "The realm of the un- 

 knowable" I call the electro-magnetic sea of ether 

 in which all things exist and from which all things 

 are evolved, which is the imperceptible elements of 

 the universe in solution. This I claim is the fourth 

 form of matter, the invisible primary essence of all 

 visible creations. 



I state his law of the redistribution of matter and 

 motion in this way : An increase of electric energy 

 produces an accelerated motion of the molecules of 

 a body or substance, and, if continued, tends to its 

 dissolution by electric repulsion; while an increase 

 of magnetic attraction decreases the activity of its 

 molecules and tends to integration or solidity of 

 form or substance. 



There is no such thing as heat in reality; heat is 

 accelerated motion, a sensation caused by the in- 

 creased activity of the molecules; while cold is 

 the absence of motion or heat.
