 CHAP. V. 



A Conformity betwixt the Motions on Earth and the Motions in the Celejlial Regions 



That Conformity will go no farther than the Nature of Things requires — The Ce- 

 Itflial Bodies not moved by Inipulfe oi o\.\\tt Bodies, as the Bodies on Earth are — nor by 



Trufion — The Suppofitions of all fuch Bodies, only fet Mind z\. z greater Diftance 



No Motion of Body by Body in the Heavens — The Reafoii of the Difference, in this 

 refpedV, betwixt Heaven and Earth — So far as the Amotions on Earth are by Mind 

 there mufl be a Conformity betwixt them and the Afotions of the Heavens — Some oeneral 

 Things in which thcfe Afotions agree. — The Queflion concerning the Compofition of 

 the Aiotion of the Celeflial Eodies — This Queftion conned^ed with the other Queftion 

 concerning the Eirfl Lazv of A'lotion — If that Law be true, the Alot'm of our Bodies 

 is neceflarily compounded : But, if it b* not true, no NeceJJiiy for any rtich Compofition 

 — Proved from Confcioufnefs, that Mind may move Body in a Curve Line, without any 

 Compofition of the Motion— This demonftrated likewife a prioriy from the Nature of 

 Motion by Mind — The Queftion examined. Whether the Aiotion of the Planets 

 though produced by Af.nd, may not be compounded — General Pofitions concerning 

 Sinip'e and Compounded Motion — Simple Motion defined — Three Kinds of Compounded 

 Aiotion — Firfl, When the Compofition is by the Aflion of different Bodies upon the 

 Body in Motion — Secundo, By the Anion both of Body and AJind upon it — Tertio, By 

 the Action of two or more Atllnds upon it, in different Directions— The two firft 

 Kinds of Compofition cannot apply to the Planets — The laft, therefore, only can be 

 applied — If the Planets be fo moved, it is a Motion without Example — All the Mo- 

 tions, we know, hy Alind, are fimple and compounded — ObjeCiion, that the C;Vc»/(?r 

 or Elliptical Motion is iTCceffarily compounded — Anfwer to this Objection The Ar- 

 gument for the Compofition of the Motion of the Planets from the fuppofed Compofition 

 of the Motion of Projei^iles, anfwered — One Difference betwixt the two Motions is, 

 that the Motion of the Projeililes is begun by Impulfe — not fo the Motion of the Planets 

 —Another is, that the Planets have not the fame Tendency to their Centre that Projec- 

 tiles have to the Centre of the Earth— Thit the Planets have fuch a Tendency, not 

 proved by any juft Argument from Analogy, nor from Final Caufes — But even the 

 Motion of the Projeiiile not compounded — This proved from the Nature of the Mo- 

 tion— Oh]zQ^ion anfwered, that the ProjeSiiU Motion may be divided — If the Projeiiile 

 Motion be not compounded^ neither is the Motion of the Planets; but it is ^ftmple Mo- 

 tion by Mind, p. 381
