Pàgina 63 - For my own part, I look upon it as upon the principle of gravitation in bodies, which is not to be explained by any known qualities inherent in the bodies themselves, nor from any laws of mechanism, but, according to the best notions of the greatest philosophers, is an immediate impression from the first mover, and the divine energy acting in the creatures.
