THE THREE SPECIES OF MOTION WITH ANSWERS TO OBJECTIONS TO THE POSSIBILITY OF MOTION


THE THREE SPECIES OF MOTION WITH ANSWERS TO OBJECTIONS TO THE POSSIBILITY OF MOTION
Have you ever wondered how an airplane moves in the air, how an arrow moves, what causes an athlete to run faster than other athletes? Have you ever imagined why it is possible for a bird to fly, and why humans cannot? Why is it possible for things to be in one position in one moment, and be found in another in the next moment? It is in the light of the above phenomenon that this paper seeks to establish the existence of what we call ‘motion’. We shall attempt a definition of motion, nature, and change. We shall also consider some issues concerned with motion, such as the reasons categories of motion. We shall also analyze the three species of motion, and consider some objections raised by some philosophers to the possibility of motion, and finally we shall consider the answers given by Aristotle to the objections of the possibility of motion.
DEFINITION OF NATURE
Natural things have in themselves an inherent principle of motion. They are either in motion or in potency to move. Aristotle defines motion as a principle of motion and change. Nature is an inner principle or the source and cause of being moved or being at rest. This implies that motion is the basic property of natural things. There is a strong relationship between nature and motion. Nature applies to both form and matter. That is, nature can be seen as both form and matter.
DEFINITION OF MOTION
Aristotle defined motion as the fulfillment of what exists in potency, in so far as it exists in potency. It is thus neither the potency of a thing existing in potency for some things are actually in potency; note the act of a thing in act. But it is the act of a thing in potency.  Motion I s also defined as the act of a mobile in as much as it is mobile. This is so because motion is the act of thing existing in potency, in as much as it is in potency, and we know that whatever is in potency is mobile, and not the mover. Consequently, motion is an act of the mobile. Aristotle clarifies this definition in his physics. He used the analogy of the bronze. The bronze is potentially a stature. But it is not the fulfillment of bronze as bronze which is motion. To be bronze, and to be certain potentiality are not the same.[1]
Motion is further defined as fulfillment or transition of a thing from point (real and imagined) to another, either from its qualitative, quantitative, substantial or special form. To set a thing in motion means to cause it to transit from potency to act. This means that only a thing which is in act can bring another from potentiality to actuality. It follows that motion is necessarily contingent upon a subject’s lack of a certain form which it is capable of receiving, and an agent possessing the perfection it is about to produce.
It should be noted that that which has the power of causing motion can only act in reference to the thing capable of being changed, and that which is capable of being changed can only suffer change under the action of that which has the power to change it. Motion cannot exist apart from the mover, for there is no abstract motion.
