Objections offered a Cartesian by some Peripateticks, against the general System of M. Descartes's World.
FIRST, they pretend to prove that the Posture and Array in which M. Descartes has marshal'd his Matter, or his three Elements in his Vortexes, thwarts and contradicts his ge∣neral Rules of Motion, which he gives himself, and the Properties he attributes to every of those Elements. And thence they'l draw such Consequences as intirely overthrow his Doctrin touching the Nature of Light.
Secondly, they will shew that his manner of explaining Light is no ways consistent with (not to repeat his Position of the Elements in the Vortexes, but) the very disposition of his Vor∣texes amongst themselves.
Thirdly, they will prove, that by the Prin∣ciples of M. Descartes, the Earth, no more than any other Planet, can be priviledg'd with a Pe∣culiar Vortex in the Vortex of the Sun. Which being once more Demonstrated, all M. Descar∣tes's Astronomy is turn'd topsy-turvy, and the whole OEconomis of his World utterly routed and destroy'd.
