COSMIC PHILOSOPHY 



kind has been created for the occasion. Induc- 

 tive proof is furnished by the fact that wherever 

 it is possible to measure both the amount of 

 motion that disappears and the amount that ap- 

 pears in its place, the two quantities are always 

 found to be equal. Thus the molar motion im- 

 plied in the fall of 772 pounds* of matter through 

 one foot of space will always raise the tempera- 

 ture of a pound of water just one degree of 

 Fahrenheit. And similar quantitative correla- 

 tions have been established among other modes 

 of motion. 



The second corollary from the persistence 

 of force asserts that the direction of motion in 

 any case is always the resultant between the 

 lines representing respectively the greatest trac- 

 tion and the least resistance exerted by the 

 forces upon which the motion depends. In any 

 plexus of forces whatever, the resultant of all 

 the tractive forces involved will be the line of 

 greatest traction ; the resultant of all the resist- 

 ing forces will be the line of least resistance ; 

 and the direction of motion in the resultant of 

 this final pair of resultants follows directly from 

 the persistence of force. For the last resultant 

 represents the direction and amount of a sur- 

 plus force which remains after all the other 

 forces have been equilibrated ; and to assert 

 that this force will not be manifested in motion
