" Without the consideration of other unseen facts, rest 

 seems to be a state without motion, and it appears that 

 motion can be created and destroyed. This is the illusion 

 to be dispelled. It is proposed to demonstrate that accelera- 

 tion in molar motion is deflection of molecular motion, and 

 in general that acceleration in any body is deflection in the 

 particles of the body."
