The natural state of matter, as to place, is a state of rest. Motion, or change of place, is the effect of an external cause acting upon matter. As to that faculty of matter called _gravitation_, it is the influence which two or more bodies have reciprocally on each other to unite and be at rest. Every thing which has hitherto been discovered with respect to the motion of the planets in the system, relates only to the laws by which motion acts, and not to the cause of motion. Gravitation, so far from being the cause of motion to the planets that compose the solar system, would be the destruction of the solar system, were revolutionary motion to cease; for as the action of spinning upholds a top, the revolutionary motion upholds the planets in their orbits, and prevents them from gravitating and forming one mass with the sun. “By ceaseless action all that is subsists; Constant rotation of the unwearied wheel That nature rides upon, maintains her health, Her beauty, her fertility. She dreads An instant’s pause, and lives but while she moves. Its own revolvency upholds the world.” In one sense of the word, philosophy knows, and atheism says, that matter is in perpetual motion. But the motion here meant refers to the state of matter, and that only on the surface of the earth. It is either decomposition, which is continually destroying the form of the bodies of matter, or recomposition, which renews that matter in the same or another form, as the decomposition of animal or vegetable substances enter into the composition of other bodies. But the motion that upholds the solar system is of an entirely different kind, and is not a property of matter. It operates also to an entirely different effect. It operates also to perpetual preservation, and to prevent any change in the state of the system. Giving then to matter all the properties which philosophy knows it has, or all that atheism ascribes to it, and can prove, and even supposing matter to be eternal, it will not account for the system of the universe, or of the solar system, because it will not account for motion, and it is motion that preserves it. When, therefore, we discover a circumstance of such immense importance, that without it the universe could not exist, and for which neither matter, nor any, nor all, the properties of matter can account, we are by necessity forced into the rational and comfortable belief of the existence of a cause superior to matter, and that cause is GOD.
