Dissertation on the Principles of the Newtonian 

 Philosophy. 



C H A f. I. 



Jn Inquiry into the Principles of the Newtonian Philofophy belongs to 

 this Work — The ^leftion concerning the Motion of the Celejlial Bodies 

 of great Importance ivith refpe^ to Natural ReligioUy and the Doclrine 

 oj Theifm-^This Do^irine confifls of tivo Parts— The Philofophy of 

 Des Cartes repugnant to the better Part of Theifm — The Philofophy 

 of Sir Ifaac Neuuton not fo Material and Mechanical ^7/ that of Des 

 Cartes — The Principles ofit^ hoijuevery ought to be carefully e^amincdy 

 as tending to the Disbelief of the Providence of God in the great ejl 

 Part of the Vifible World — The Account of the Motion of the Celeflial 

 Bodies given by Sir Ifaac — Their Motion compofed of the tivo Motions 

 ofProjedion and Gravitation — One of thcfe tivo Motions Mechanical 

 — 5/r Ifaac' s Philofophy in his Principia incompleat-, as it accounts only 

 for one of thefe tivo Motions — Sir Ifaac in vain endeavoured tofupply 

 this Defe5l aftervoards — All the Caufes of Gravitation that can pof^ 

 fibly be affigned — The lajl Caufe mentioned^ viz. the conflant Agency of 

 Mind, the true Caufe — This adopted by the Neivtonlans at prefent, and 

 a great Improvement of Sir Ifaac'* s Syflem^But a fart her Amendment 

 is neceffary, 



F T E R reading over the Nineteenth Chapter of the Second 

 Book of the preceding volume, concerning the Newtonian Phi- 

 lofophy, and converfing and xorrel ponding upon the fubjed with 

 fome friends very much more learned than I in tliat philofophy, I 

 have thought proper, by way of Appendix to this part of my work, to 

 fubjoin a DiiTertation upon the fame fubjed, in which I propofe to fay- 

 nothing concerning the geometrical, mechanical, and agronomical 

 principles of the Newtonian fyftem, thefe having been already fufll- 

 c i en tbi- examined by others more capable to judge of them, but to in-
