EXPLAINS NATURAL PHILOSOPHY 159 



a vivid series which includes all sense experience, 

 and second, a faint series which includes thought, 

 as in speculation and deliberation. Force, he con- 

 tends, is the ultimate and deepest truth of the 

 universe. All forms of consciousness, lie says, are 

 derived as experiences of force. All sense experi- 

 ences as in the objective series, all subjective feeling 

 or thought, everything known or knowable, is a 

 manifestation of the one universal force or energy. 

 This universal force, I contend, is, first, spirit or 

 mind force; second, electric force controlled by mind

He says : " Contemplating pure force, we are ir- 

 resistibly compelled by the relativity of our thought 

 to vaguely conceive some unknown force as the 

 correlative of the known force." This unknown or 

 imperceptible force I contend is electricity and the 

 mental force back of it. All our ideas of matter 

 and motion, he says, are ideas of force. The demon- 

 strated fact of the indestructibility of matter is 

 but another name for the indestructibility of force. 



The persistency of force means also the persistency 

 of motion. All forms of physical energy as light, 

 heat, sound, electricity, magnetism, chemical action, 

 gravity and sensible motion he says, are different 

 manifestations of force. In this I fully agree with 

 him and claim these are all manifestations of the 

 one fundamental force in nature electricity. 



He says : "Even after all has been said, many 

 will be alarmed by the assertion that the forces we 

 designate as mental come within the same general- 

 ization. Yet there is no alternative but to make 

 this assertion. The facts which justify or rather 

 necessitate it being abundant and conspicuous. All
