Can it have motion without an equal of cause ? Again,—46 Motion, once impressed, would cause a body to move for ever in empty space, because it cannot stop itself, owing to its inertia55^ • which is refuted by the dynamic axiom : No effect can exceed its cause or be produced by less than its equal of cause.
