Strona xx - All these things considered [that is, the chemical facts he had just recited], it seems probable to me that God in the beginning formed matter in solid, massy, hard, impenetrable, movable 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...
Strona vi - To this purpose the philosophers say that Nature does nothing in vain, and more is in vain when less will serve; for Nature is pleased with simplicity, and affects not the pomp of superfluous causes.
Strona xx - 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.
Strona vi - The qualities of bodies, which admit neither intension nor remission of degrees, and which are found to belong to all bodies within the reach of our experiments, are to be esteemed the universal qualities of all bodies whatsoever.
Strona vi - RULE IV. In experimental philosophy, we are to look upon propositions collected by general induction from phenomena as accurately, or very nearly true, notwithstanding any contrary hypothesis that may be imagined, till such time as other phenomena occur, by which they may either be made more accurate, or liable to exceptions...
Strona xix - All these things being considered, it seems probable to me, that God in the beginning formed matter, in solid, massy, hard, inpenetrable, 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...
Strona 319 - Experiments analogous to the former, and equally simple, may also be made with many metallic solutions. If, for instance, the solution contains copper, it will be precipitated by a piece of iron, and appear on its surface. Upon silver merely immersed in the same solution, no such effect is produced ; but, as soon as the two metals are brought into contact, the silver receives a coating of copper.
Strona xxii - is not deduced from phenomena, is to be called an hypothesis : and hypotheses, whether physical or metaphysical, whether of occult qualities or mechanical, have no place in experimental philosophy.
Strona xx - 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. 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 particles in the beginning. And, therefore, that nature may...
Strona 474 - Os homini sublime dedit, — ccelumque tueri Jussit, — et erectos ad sidera — tollere vultus.
