Página 50 - And I will establish my covenant with you; neither shall all flesh be cut off any more by the waters of a flood ; neither shall there any more be a flood to destroy the earth.
Página 47 - Of old hast thou laid the foundation of the earth: and the heavens are the work of thy hands. They shall perish, but thou shalt endure: yea, all of them shall wax old like a garment; as a vesture shalt thou change them, and they shall be changed: But thou art the same, and thy years shall have no end.
Página 108 - 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.
Página 107 - 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 divide what God himself made one in the first Creation.
Página 108 - But should they wear away, or break in pieces, the Nature of Things depending on them, would be changed. Water and Earth, composed of old worn Particles and Fragments of Particles, would not be of the same Nature and Texture now, with Water and Earth composed of entire 817 Particles in the Beginning. 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...

Página 114 - Have not the small Particles of Bodies certain Powers, Virtues, or Forces, by which they act at a distance, not only upon the Rays of Light for reflecting, refracting, and inflecting them, but also upon one another for producing a great Part of the Phenomena of Nature?
Página 108 - Particles, would not be of the same Nature and Texture now, with Water and Earth composed of entire Particles in the Beginning. 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; compound Bodies being apt to break, not in the midst of solid Particles, but where those Particles are laid together, and only touch in a few Points.
Página 313 - But such a personification of "force" is a remnant of barbaric thought, in no wise sanctioned by physical science. When astronomy speaks of two planets as attracting each other with a " force " which varies directly as their masses and inversely as the squares of their distances...
Página 115 - Forms of Things, but as general Laws of Nature, by which the Things themselves are form'd; their Truth appearing to us by Phaenomena, though their Causes be not yet discover'd.
