Nature of Motion
Motion should not be considered as an abstraction, separated from space and time. It should not be analyzed into abstract ideas such as movement, velocity, and force. Mathematical considerations of spatial and temporal infinitesimals lead to paradoxes. Motion should not be equated with the cause of motion. To say that the quantity of motion is always conserved is to confuse motion itself with the force that causes motion. The force of the cause of motion is conserved. Motion is not an internal, living force in things. It is a lifeless, indifferent effect.
