Jierent in matter, but forces impressed upon it, ab extra,

Matter, 4. All our doubts about the inactivity, or resistanceof matter, may be solved, by considering, what force ormoment in a moving body is, i. 58, zo. This also mayconvince us, that unless matter resisted a change of state,the action of matter upon matter would be impoffible, i.59, 21. Matter unresisting, has no less need of an imma-terial mover, than resisting matter; nay, is a more disad-vantageous supposition to the atheist, than resisting mat-ter, i. 60, 22. What has been concluded of matter in ge-neral, must be true of every part of it, and thews the ab-surdity os a system of resisting, unactive matter, induedwith particular powers and qualities, ibid. f. See Lock,

■-5. The necessity of its resistance, and its connection-

with solidity, more particularly evidenced, by consideringits use, both in our own and other animals bodies, in oneparticular respect, ‘viz. that of progressive motion, eitherof the whole, or parts thereof, i. 66, 23, 24, 2;. Onlysusceptible of pressure, tension, and pulsion, because of re-sistance, ibid. As a solid extended substance, it must ne-cessarily resist all change of its state of rest or motion, i,73, 26. Otherwise it would follow, that two contradicto-ry propositions could be both true, ibid. And it is much-to be doubted, whether there be any matter in the worldbut what suffers pressure, r, ibid. Another short and easyway of proving, that this vis inertia;, or resistance, is asessential a property of matter, as solidity itself, i. 76, 27.Its being a solid extended substance, thews there can beno universal plenum, i. 82, 2.

— . 6. The point of a constant impression made upon

matter, ab extra, is wonderfully plain, by considering themotion of the earth, and other planets, i. 101, 6. Itsresistance, to change its state of rest, greatest, where theforce of inactivity, to remain in that state, is least, i. 11,,,10, and i. 115, 11, x, ibid. Matter in the bodies of a-siimals, resists as much the change of its state, as any ci-ther matter, i. 119, 12, ctf seqq. and requires as much anmimaterial mover, ibid.
