"From his considerations of the nature of motion in Physics, in Book 8, Aristotle concludes that there must be a logically first unmoved mover in order to explain all other motion. In Physics 8.1, he argues that motion is eternal. Motion cannot begin without the prior existence of something to impart motion in another thing, so that there will always be something in motion, since something at rest cannot cause motion in another thing. In addition, if motion were not eternal, then time would not have always existed, since time is the measure of motion; but, according to Aristotle, no one would be willing to say that time has not always been in existence. Nor can motion cease, since to do so something must cause it to cease, but then the thing that caused motion to cease would require something to cause its cessation and the process would continue ad infinitum. Aristotle concludes, "That there never was a time when there was not motion, and never will be a time when there will not be motion" (252b 6-8). Aristotle also objects to the idea that motion may have begun self-caused; he points out that, in those things in which motion is said to be "self-caused," in fact, there is a part of the thing that is already in motion and imparts motion to the whole. Self-caused means that motion is not imparted from without but from some part of the whole that is already in motion. In such cases, the motion of the part that moves the other parts of a things requires a mover.

Since everything is moved by something and since motion is eternal, Aristotle concludes that there must be something that imparts motion without itself being moved; otherwise, there would be an infinite regress of movers, the moved and instruments of moving, which is unacceptable (Physics 8.5). (An axiom for Aristotle is that an infinite regress is impossible.) According to Aristotle, all movable things are only potentially in motion, and require something else to act upon them in order to be set in motion: "So it is clear that in all these cases the thing does not move itself, but it contains within itself the source of motion—not of moving something or of causing motion, but of suffering it." (Physics 8.4; 255b 29-31). Thus, if there were no unmoved mover, there could be no motion, because a moved mover requires a cause of its own motion and no infinite regress is possible. In Physics 8.6, Aristotle argues that, since motion is both eternal and necessary, the first mover must be equally eternal and necessary. Because those things involved in the eternal and continuous process of motion are not eternal and necessary, since they come into being and perish, there must be one or many eternal and necessary thing or things outside the process of motion that imparts or impart motion to the things in motion. This is the only way that there could be any motion, for non-eternal and contingent movers cannot explain all motion, because their own coming into existence needs a cause. He explains, "There is something that comprehends them all, and that as something apart from each one of them, and this it is that is the cause of the fact that some things are and others are not and of the continuous process of change" (Physics 259a 3-5). It is not possible to explain eternal motion by postulating a plurality of unmoved movers capable of imparting motion but that do not exist eternally, for "There must clearly be something that causes things that move themselves at one time to be and at another time not to be" (Physics 258b 21). Aristotle determines that there is only one unmoved mover, not only because many unmoved movers are unnecessary, but because only one mover could produce a continuous motion, in the sense of being an interconnected system of causes and effects. Moreover, since it is continuous, motion is one; one effect requires a single cause, so that the unmoved mover must also be one. He concludes that an unmoved mover causing eternal motion must likewise be eternal (Physics 260a 1-2)."
