Страница 28 - All these things being considered, it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, moveable particles, of such sizes and figures, and with such other properties and in such proportion to space as most conduced to the end for which he formed them; and that these primitive particles being solids are incomparably harder than any porous bodies compounded of them, even so very hard as never to wear or break in pieces, no ordinary power being able to...

And therefore that nature may be lasting, the changes of corporeal things are to be placed only in the various separations and new associations and motions of these permanent particles...

Страница 28 - ... even so very hard as never to wear or break in pieces ; no ordinary power being able to divide what God himself made one, in the first creation. While the particles continue entire, they may compose bodies of one and the same nature and texture in all ages ; but should they wear away or break in pieces, the nature of things depending on them would be changed.
