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.
