"…a thing’s moving of itself is nothing other than its being the cause of its own motion. That which is itself the cause of something must primarily agree with it. For that which is first in any genus is the cause of the things that come afterward. Thus fire, which is the cause of heat itself and for others, is the first hot thing. However, Aristotle has shown in Book VI that there is no first in motion or in time or in magnitude or in the mobile object because of its divisibility. Therefore, there cannot be discovered a first whose motion does not depend on something prior. For the motion of a whole depends on the motion of its parts and is divided into them, as was proven in Book VI. Therefore, Aristotle thus shows the reason why no mobile being moves itself. For there cannot be a first mobile object whose motion does not depend on its parts; just as if I were to show that a divisible thing cannot be the first being because the being of whatever is divisible depends on its parts. And thus this condition is true: ‘if a part is not moved, the whole is not moved’, just as this condition is true: ‘if the part is not, the whole is not’."
