290 COSMIC PHILOSOPHY, [pt. U. 



Besides this purely philosophical corollary from our 

 fundamental axiom, we have to note three other corollaries, 

 which, as belonging to the transcendental regions of physical 

 science, must be set forth and illustrated before we can 

 profitably begin our synthesis of scientific truths. Let us 

 briefly consider these in their natural order. 



The first of these corollaries is the generalization currently 

 known as the "Correlation of Forces." Since each mani- 

 festation of force must have been preceded by some other 

 equivalent manifestation of force, it follows that when any 

 specific manifestation appears to terminate, it does not really 

 cease to exist, but is only transformed into some other specific 

 manifestation. That we may better apprehend this important 

 truth, let us clear away some of the ambiguity which 

 surrounds the terms commonly employed in the statement of 

 it. The phrase "correlation of forces," which means the 

 correlation of sensible motion with heat, light, electricity, 

 etc., implies that heat, light, and electricity are forces. This 

 is not strictly accurate. Heat and light are modes of 

 nndulatory motion, and electricity, with its kindred pheno- 

 mena, is to be similarly interpreted. Now motion is not 

 force, but one of the manifestations of force ; and so the 

 various modes of motion, molar and molecular, are differently 

 conditioned manifestations of force. The force which pro- 

 duces or resists motion is known by us only under the 

 twofold form of attraction and repulsion, which may be 

 either polar or universal. Polar attraction or repulsion is 

 that which acts with different power in different directions. 

 An example of polar attraction is to be found in every case 

 of crystallization, where molecules are grouped into a solid 

 figure bounded by plane surfaces ; and a familiar example of 

 polar repulsion is that which is exhibited when the positive 

 poles of any two magnets are brought into mutual proxi- 

 mity. Universal attraction or repulsion is that which
