The
Process of Change
by Aristotle
Everything which comes into being is brought
about by something, that is, by a source from which
its generation comes. And it is composed of
something. Now this latter is best described not as
the absence of the thing but as the matter from
which it comes. And it becomes a particular thing,
as a sphere or a circle or some other thing. Now
one does not "make" the material -- as the bronze
-- of which a thing is composed; so one does not
make the sphere, except in a secondary sense, in so
far as the bronze circle is a circle and one makes
it. For the act of making a particular thing is a
process of making it out of some material in
general. I mean that to make the bronze round is
not to make the "round" or the "sphere," but quite
a different thing -- that of putting this form into
what did not have it previously. If one made the
"form," one would make it out of something else,
for this would underlie it, as when one makes a
sphere out of bronze. This is done by making of a
particular kind of substance, namely bronze, a
special sort of thing, namely a sphere. And if one
makes this "sphere" also in the same way, it is
evident that he will make it in the same manner,
and the process of origination will go on to
infinity. It is evident therefore that the form, or
whatever one ought to call the shape of the
perceived object is not "made." It does not
"become," nor does it have an origin. Nor is there
any for the essential conception of a thing. For
this is what is implanted in another entity, either
by training or by nature or by force. But one does
cause the "bronze sphere" to be. For one
makes it out of bronze and the form of "sphere."
One puts the form into this matter, and it is then
a bronze sphere. But if there is an origin for "the
idea of sphere in general" it will be something
generated from something else. That which is
generated will have to be analyzed again in turn,
and each reduced to something further, then that to
something else; I mean in one aspect into matter,
in another into form. A sphere is a figure whose
surface is everywhere equally distant from a
center. One aspect of it is the material into which
the form is to be put; the other the form which is
to be put into it. The whole is what results,
namely, the bronze sphere.
It is evident from what we have said that the
part which is spoken of as the form or the essence
does not originate; but the combination which
derives its name from this does; and in everything
which originates there is matter, and it is now
this thing, now that. Is there then a "sphere"
beside the particular spheres? Or is there a
"house" beside the houses of brick? Or would there
never be any particular things if this were so? The
genus gives the general character, but is not a
definite particular thing. But one makes and
produces such and such a thing out of "this"
particular substance. And when it has been produced
it is "this thing of such and such a kind." This
concrete existing thing is "Kallias" or "Socrates,"
just as the other was "this bronze sphere," but it
is man and animal in general just as the other was
a bronze sphere in general. It is evident then that
the formal principle, as some are accustomed to
speak of forms, if they are something aside from
the particulars and beside the acts of generation
and the essences, is of no use. For not by virtue
of them would there be particular instances of
them. In some cases indeed it is evident that that
which causes is the same sort of thing as that
which is caused, yet not identically the same, nor
one numerically, but in form -- as in the case of
the products of nature. Man begets man, (and so it
is), except where something arises of different
nature, as when a horse begets a mule. Yet these
cases also are really similar to the others; but
what is common to a horse and an ass has not been
given a name as a "proximate genus"; perhaps it
would be "mule."
So it is evident that it is not at all necessary
to supply forms as patterns, (for they would have
to be found in these cases especially, since these
are certainly substances). The begetter is adequate
to the production of the effect and to the
embodiment of the form in the matter. And the
compound -- such and such a form in this flesh and
these bones -- is Kallias or Socrates. They differ
because of their matter, for it is different, but
they are the same in form. For the form is
indivisible.
Of things which come into existence some are
generated by nature, some by art, some by chance.
And all things which are generated are generated by
something and from something and as some particular
thing. Some particular thing, I mean with respect
to each category, such as substance, quantity,
quality or place. Origination by nature occurs in
the case of those things whose origin is through
the processes of nature. The substance of which
they are formed we call matter; the source from
which they arise is some thing in nature; the kind
of thing which they become is "man" or "plant" or
some other thing of the kind which we are
especially accustomed to call "substances." All
things which have an origin, whether by nature or
by art, have a material. Each of them might exist
or not exist; and the seat of this double
possibility is the material part of them. In
general that out of which and in accordance with
which they arise is some natural thing. For that
which comes into being has some natural character
as that of a plant or an animal. And that under the
influence of which it arises is a natural object
which with reference to its form may be said to be
homogeneous. And this form is found in another
individual; as one man begets another man. In this
way arise the things which come about by nature;
but other originations are called artificial
creations.
Artificial creations result from acquired skill,
or external power, or deliberate planning. Some of
these also come about spontaneously and by chance,
in nearly the same manner as some things are
generated by nature. For there some kind of things
arise in some instances from seed, in other
instances without seed. Into these things we shall
have to look later; but those things arise by art,
the forms of which are in some one's mind. And by
form I mean the essential conception of the thing
and its fundamental essence. And indeed in a
certain sense opposites have the same form. The
opposed essence is that of the absence of the given
thing, as health is the absence of disease. For by
the absence of the former disease becomes manifest.
But health is the determining principle, in the
soul and in knowledge. The healthy condition of one
who has been ill comes about as follows: since such
and such a condition is health it is necessary, if
there is to be health, that some other condition
exist, as uniform temperature, and if there is to
be uniform temperature then warmth. And in this
manner one continues one's analysis until one
arrives at a certain thing which one can do as the
first step. The activity which comes from this is
an artificial productivity, in this case the
production of health. So in this I sense it is true
that health comes from health, and a house from a
house, that which has material content from that
which B does not. The essence of the physician's
art and of the builder's art is the form of health
and the form of the house. And the essence without
matter I call the essential conception.
One aspect of the process of production and of
action is called the intellectual contemplation,
the other the practical effecting of them. The one
which has to do with the principle and the form is
intellectual contemplation. That which refers to
the aim of the intellectual contemplation is the
practical application. And each of the intermediate
steps has the like phases. For instance, if one
will be healthy it is necessary to have an even
temperature. What does the maintenance of an even
temperature involve? This: it will result if one is
kept warm. And what will do this? The following;
but this exists only as a possibility. Yet it is in
one's power. So then the action and the source from
which the development of the healthy state springs,
if it is from an artificial source, is the "form"
in one's mind; but if from chance, still it results
from something which at sometime or other is the
source of activity used by him who acts with
conscious skill. In the case of medical treatment
perhaps the source is in causing warmth, and one
produces this by rubbing. So the warmth in the body
is either a part of health or there follows it
something of a kind which is a part of health, or
is so after some intermediate stages. And this last
step is what causes the essential part and what is
thus a part is to health as the stones are to a
house; and likewise with other things.
As we have said, nothing can arise unless
something preexists. Therefore that some part
necessarily exists is evident. For the material
part is a part. And it enters into a thing and
pervades its changes. And so it is also with the
things mentioned in our statement. We tell what
bronze circles are by distinguishing two phases;
saying of the material that it is bronze; and of
the form that it is such and such a shape. And this
is the genus under which it is placed first. The
brazen circle includes matter in its notion. Some
things receive names from the matter out of which
they come when they arise, being said, of course,
to be not " that substance" but "of that
substance," as the image of a man is said to be not
"stone" but "of stone." But a healthy man is not
designated from that out of which he has come. The
reason for this is that he has come from a
condition opposite to his present one, as well as
out of a substance which we call his material
being. Thus it is both a man and a sick man who
becomes well. But the statement is made rather with
reference to the negative state; one becomes
healthy from being ill rather than from being a
man. Consequently the well person is not said to be
ill, but a man and a healthy man. But in those
things to which there is no evident opposite, or
none with a name, as of any kind of form in bronze,
or the bricks or boards of a building, generation
is said to be out of these, as in the other case it
was out of the condition of illness. Wherefore, as
in that case that from which this comes is not used
in the name, so here the image of the man is not
called "wood" but is styled "wooden," or "brazen"
not "bronze," or "stony" not "stone"; and a house
is said to be "of brick" not "bricks." Nor does the
image come from wood, nor the house from bricks, if
one looks at the matter exactly; and one could not
say this without qualification, for it is necessary
that generation come through the changing of a
source -- through its not remaining permanent. For
these reasons then we use such modes of
expression.
