CONSTITUENTS OF THE UNIVERSE. 



The third item of proof ventured in behalf 

 of matter is that it has weight. But there is 

 no weight, for that is simply one of the several 

 manifestations of mass-motion, that has less 

 claim to be called weight than other motions 

 that we know to have none. THAT motion is 

 a balanced motion, and the whole earth weighs 

 nothing for that reason, and also for the addi- 

 tional reason that NO MODE OF MOTION has any 

 weight. 



Now, the believers in the existence of mat- 

 ter recognize that truth when they admit that 

 heat, light and electricity are only different 

 modes of motion. They say that all matter 

 has weight, and in so doing, they draw a line 

 between these three items and what they call 

 matter. As there is no such thing as weight, 

 they must consistently admit that there is 

 nothing but motion, or be obliged to accept the 

 proposition that heat, light and electricity are 

 also matter. In point of fact, but one con- 

 clusion is admissible; either they are all mat- 

 ter, or they are all motion arid motion only.
