On the
Subject of Intellect
by Al-Kindi
I have taken note that you ask that a brief
discussion of the intellect [and the object of
comprehension], according to the theory of
Plato and Aristotle, be communicated to you. Their
theory is that intellect falls into four types. The
first is the intellect which is always active; the
second is the intellect potentially in the mind;
the third is the intellect when it becomes an
efficient agent by virtue of [its] power in
the mind; the fourth is the intellect which we call
demonstrative, and it is this intellect which
Aristotle approximates to sensation, because of the
propinquity of sensation to truth and because it is
in complete communion with it.
For Aristotle has said that there are two kinds
of form. One of them has matter and it is that
which underlies sensation; but the other is that
which is devoid of matter and is that which forms
the substratum of intellect. Indeed, the former has
to do with things, while the latter is above
that.
Now, the form that resides in matter, is
actually perceived; for if it were not actually
perceived it would not lie within the range of
sensation. Now, if the mind apprehends it, then it
is as such in the mind. But it does not apprehend
it unless it was first potentially in the mind.
Therefore, when the mind apprehends it, it becomes
actual in the mind. However, it is not in the mind
as something is in a vase, nor does it chase
through the body; for the mind is not the body, nor
is it limited. Therefore, it is in the mind, and
the mind is one, identical with itself, and not
anything other than itself; nor is it again
different by virtue of a twisting of terms
Similarly, the faculty of feeling does not exist
except in the soul. But it is not part of the soul
as a member is part of the body; rather, it is the
soul itself, and as such is feeling. Likewise, the
form of the sense datum is not in the mind as
something distinct or different. Therefore, as
Aristotle has declared, the sense datum in the mind
is the perceiving agent in conformity to what is in
the mind. But, the sense datum as a material thing
is outside the perceiving mind. Now, therefore,
that which is in matter is the sense datum, not the
perceiving agent.
Similarly, Aristotle has explained intelligence
as the mind when it apprehends the object of
comprehension, or THE form which has neither matter
nor sensuous representation and is one with mind,
and is then in actuality in the mind; for it was
not previously in actuality, but [only]
potentially in the mind. This form, therefore,
which hasn't any matter or sensuous representation
as yet, is the intellect which the mind has
attained through primal intelligence, the concept
of all, ever active. However, this does not become
contributive, unless the mind has attained the
power to receive it, since the mind is
[only] potentially an agent of
intelligence, whereas primal intelligence is always
active. For nothing assimilates anything through
its own receptivity except that which belonged to
it potentially and not in actuality. Nothing, to be
sure, that a thing possesses potentially works as
an efficient cause by itself; for if it were
self-existent, it would always be in activity;
since its essence would always be its own and
spontaneous. Therefore, nothing that exists
potentially becomes an efficient cause unless by
virtue of something that is an efficient cause.
Hence, the mind is potentially an agent of
intelligence, yet it becomes an efficient cause at
the instigation of primal intelligence, looking to
which it becomes an agent of intelligence in
actuality. And, when an intelligible form is
conjoined with it, it is not one thing, and the
intelligible form another, because it is not
divisible, allowing it to be changed. But when a
union is brought about with the intelligible form,
then it and the intellect are one, if you will
allow the agent of intelligence and that which is
comprehended. Thus, the intellect and the object of
comprehension are one when they exist in the mind.
In truth, the intellect as such, which is always
active and draws forth the mind so it may become an
agent of intelligence in fact, after it was
potentially intelligent, and the object of
comprehension as such are not one and the same
thing. Therefore, the object of comprehension in
the mind and the first type of intellect derived
from primal intelligence are not the same; however,
the intellect derived from the mind and the object
of comprehension are one and the same.
But the intellect, which in simplicity is more
like the soul, is much higher in comparison with
the thing comprehended than sensation, as compared
with the sense datum. The first type of intellect,
therefore, is the cause of all that is
comprehended. But the second type of intellect is
potentially in the mind.
Intellect is, thus, either of the first type in
that it is for all that is comprehended, or it is
of the second type and then it is potentially in
the mind; at all events, the mind is not an actual
agent of intelligence. The third type of intellect,
however, is the one that is working efficiently in
the mind which has already acquired it. And, it is
kept there in such a manner that, when it wills, it
may use it and cause it to be in one other than
itself. In the same way, writing is ready and easy
for a scribe because he has already become
proficient in it and it has become second nature to
him. Consequently, he communicates and practices it
whenever he is so inclined. The fourth type of
intellect is that which goes forth from the mind
which, when you desire to communicate it, will work
an effect in someone other than yourself.
The second type of intellect derives, therefore,
from the the third and fourth, for the reason that
the third is an acquisition of the mind and causes
it to appear whenever it wishes, either at the
first instance of its acquisition in us, or in the
second instance of its appearance outside us. Then
the mind uses it. Therefore, the third is the one
that is an acquisition of the mind, which is prior
to it, and, if it so wills, becomes spontaneous in
it. But the fourth is that which appears to work as
an efficient cause from the mind.
These are, therefore, the parts into which the
foremost philosophers have divided the intellect.
May this explanation suffice for what you had in
mind.
