Hiuch resisting matter to all change os stats,-as here it is contended to be ; and supposesthis resistance only overcome by the impulseof other matter. And, secondly, as to thisother matter of such subtile fluid, it is evi-dent, it must be as much resisting matter toall change of its state, 9.S the matter ofthese bodies themselves, which we know,is shewn to be. The moment or force ,which it hath in its motion, and with whichit impels these bodies, manifests this. Letit be observed; the powers of gravity , ela-fiicity , repulfon , attraSlion , can no more belodged in the matter of this fuid than in thematter of the real bodies we have been speak-ing of and that for the same reason, assign-ed above: for this is as contradictory in re-spect of one sort of matter as another, inrespect of a very small particle as of a muchgreater one, being a palpable contradictionin respect of all matter equally. The mat-ter of this fluid then being, in all respects,matter that resists a change of its state, wemust still as much seek a cause of its mo-tion ab extra to it, that is, in effect, insomething not matter , in some immaterialcause, or being, (unless we would be open-ly
