CHAPTER I. 



The Deftgn of this Work is to reftore the Antient Philofophy, — Tn the 

 preceding Volumes it is /Jjoivh that Mind is the Author of all the 

 Motions in the Univerfe. — The principal Motions that fall under 

 our Obfernjation are the Motions of the Celefial Bodies. — Thefe made 

 to he entirely Mechanical by Sir Ifaac Neivton ivhen he ivrote his 

 Principia. — Some Alterations made in Sir Ifaac s Syflem by the later 

 Newtonians— but all agree that the Progreffive Motion af the 

 Planet is carried on ivithout Mind ; — the only ^uefion, ivhether 

 by Virtue of an Original Impulfe, or by Virtue of a Vis Infita in 

 the Planet. — But the Vis Centrifuga of the Planet irreconcikable 

 nvith the Motion being by Virtue of an Original Impulfe-— therefore 

 it muji be by a Vis In^n^.—Of the beginning of the Progreffive 

 Motion of the Planets.— 1 he Newtonians noiv admit it is by Mind. 

 —hut it goes on by //j^ Vis Infita, after the Energy of Mind has 

 ceafed.-^rhis a mof extraordinary Pofition.—Suppofe the Body not 

 projeEled in a Straight Line, but beginning its Motion in the Curve,
