Of the Aristotelian Distinction Between Actuality and Potentiality.

QUESTIONS TO BE DISCUSSED.

1. (Aristotle  ) spoke of (things) existing “potentially,” and “actually”; and actuality is spoken of as a “being.” We shall, however, have to examine this potential and actual existence; and whether this actual existence be the same as actuality, and whether this potential existence be identical with potentiality; also, whether these conceptions differ so that what exists actually be not necessarily actuality. It is evident that among sense-objects there exist things potentially. Are there also such among the intelligibles? This then is the problem: whether the intelligibles exist only actually; and on the hypothesis of the existence among intelligibles of something existing potentially, whether, because of its eternity, this always remains there in potentiality; and, because it is outside of time, never arrives to actuality.

DEFINITION OF POTENTIALITY.

Let us first define potentiality. When a thing is said to exist potentially, this means that it does not exist absolutely. Necessarily, what exists potentially is potential only in relation to something else; for example, metal is the statue potentially. Of course, if nothing were to be done with this thing, or within it, if it were not to become something beyond itself, if there were no possibility of its becoming anything else, it would only be what it was already. How could it then become something different from what it was? It did not, therefore, exist potentially. Consequently, if, on considering what is a thing that exists potentially, and one that exists actually, we say that it exists potentially, we must mean that it might become different from what it is, whether, after having produced this different thing, it remain what it is, or whether, on becoming this different thing, which it is potentially, it ceases being what it is itself. Indeed, if metal be a statue potentially, this is a relation different from water being metal potentially, as air is potentially fire.

DISTINCTION BETWEEN EXISTING POTENTIALITY AND POTENTIALITY.

Shall we say that what thus exists potentially is potentiality in respect of what is to be; as, for instance, that the metal is the potentiality of a statue? Not so, if we refer to the producing potentiality; for the producing potentiality cannot be said to exist potentially. If, then, we identified existing potentially not only with existing actually, but also with actuality, then potentiality would coincide with potential existence. It would be better and clearer, therefore, to contrast potential existence with actual existence, and potentiality with actuality. The thing which thus exists potentially is the substance underlying the reactions, shapes and forms which it is naturally fitted to receive, to which it aspires for their betterment or deterioration, and for the destruction of those whose actualization constitutes differentiation.

MATTER IS NOTHING ACTUALLY.

2. As to matter, we shall have to examine whether it be something actually, while simultaneously it potentially is the shapes it receives; or whether it be nothing at all actually. Everything else of which we predicate potentiality passes on to actuality on receiving its form, and remaining the same. We may call a statue an actual statue, thus contrasting with it a potential statue; but an actual statue will not be implied by the metal which we called the potential statue. Consequently, what exists potentially does not become what exists actually; but from what was previously a potential (statue) proceeds what later is an actual (statue). Indeed, what exists actually is the compound, and not the matter; it is the form added to matter; this occurs when there is produced another being; when, for example, from the metal is made a statue; for the statue exists by this very being something other than the metal; namely, the compound.

IN PERMANENT THINGS, POTENTIALITY AND ACTUALITY MAY COINCIDE.

In non-permanent things, what exists potentially is evidently something quite different (from what is said to exist actually). But when the potential grammarian becomes an actual grammarian, why should not the potential and actual coincide? The potential wise Socrates   is the same as the actual Socrates. Is the ignorant man, who was potentially learned, the same as the learned? No: only accident makes of the ignorant man a learned one; for it was not his ignorance that made him potentially wise; with him, ignorance was only an accident; but his soul, being by herself disposed (to be actually learned), still remains potentially learned, in so far as she was actually so, and still keeps what is called potential existence; thus the actual grammarian does not cease being a potential grammarian. Nothing hinders these two different things (of being a potential and actual grammarian) from coinciding; in the first case, the man is no more than a potential grammarian; in the latter, the man is still a potential grammarian, but this potentiality has acquired its form (that is, has become actual).

DIFFERENCE BETWEEN GENERAL AND PARTICULAR ACTUALITY.

If however what is potential be the substrate, while the actual is both (potential and actual) at the same time, as in the (complete) statue, what then shall we call the form in the metal? We might well call the actuality by which some object exists actually, and not merely potentially, the form and shape; therefore not merely actuality, but the actuality of this individual thing.

THE FORM ADDED TO MATTER IS THE SPECIFIC ACTUALITY.

The name actuality would better suit the (general) actuality rather (than the actuality of some one thing); the actuality corresponding to the potentiality which brings a thing to actuality. Indeed, when that which was potential arrives at actuality, it owes the latter to something else.

WHAT IN THE BODY IS A PASSIVE CAPACITY, IN THE SOUL IS AN ACTIVE FACULTY.

As to the potentiality which by itself produces that of which it is potentiality, that is, which produces the actuality (corresponding to this potentiality), it is a (Stoic) “habituation;” while the actuality (which corresponds to this habituation) owes its name thereto; for instance, the “habituation” is courageousness; while the actuality is being brave. But enough of this!

INTELLIGIBLE MATTER IS NOT POTENTIAL.

3. The purpose of the preceding considerations was to determine the meaning of the statement that intelligibles are actual; to decide whether every intelligible exist only actually, or whether it be only an actuality; and third, how even up there in the intelligible, where all things are actualities, there can also exist something potentially. If, then, in the intelligible world, there be no matter which might be called potential, if no being is to become something which it not yet is, nor transform itself, nor, while remaining what it is, beget something else, nor by altering, cause any substitution, then there could not be anything potential in this World of eternal essence outside of time. Let us now address the following question to those who admit the existence of matter, even in intelligible things: “How can we speak of matter in the intelligible world, if by virtue of this matter nothing exists potentially? For even if in the intelligible world matter existed otherwise than it does in the sense-world, still in every being would be the matter, the form and the compound which constitutes it.” They would answer that in intelligible things, what plays the part of matter is a form, and that the soul, by herself, is form; but, in relation to something else, is matter. Is the soul then potential in respect of this other thing? Hardly, for the soul possesses the form, and possesses it at present, without regard to the future, and she is divisible in form and matter only for reason; if she contain matter, it is only because thought conceives of her as double (by distinguishing form and matter in her). But these two things form a single nature, as Aristotle also says that his “quintessence” is immaterial.

THE SOUL IS THE PRODUCING POTENTIALITY; NOT THE POTENTIALITY OF BECOMING.

What shall we say? Potentially, she is the animal, when it is unborn, though to be born. Potentially she is the music, and all the things that become, because they are transient. Thus in the intelligible world there are things which exist, or do not exist potentially. But the soul is the potentiality of these things.

IN THE INTELLIGIBLE WORLD EVERYTHING IS ACTUAL.

How might one apply actual existence to intelligible things? Each of them exists actually because it has received form, as the statue (the compound) exists actually, or rather, because it is a form, and because its essence is a perfect form. The intelligence does not pass from the potentiality of thinking to the actuality of thinking. Otherwise, it would imply an anterior intelligence which would not pass from potentiality to actuality, which would possess everything by itself; for what exists potentially implies another principle whose intervention brings it to actuality, so as to be something existing actually. A being is an actuality when it always is what it is, by itself. Therefore, all first principles are actualities; for they possess all they should possess by themselves, eternally. Such is the state of the soul which is not in matter, but in the intelligible world. The soul which is in matter is another actuality; she is, for instance, the vegetative soul; for she is in actuality what she is. We shall, therefore, have to admit that (in the intelligible world) everything exists actually, and that thus everything is actuality, because it has rightly been said that intelligible nature is always awake, that it is a life, an excellent life, and that there on high all actualities are perfect. Therefore, in the intelligible world, everything exists actually, and everything is actuality and life. The place of intelligible things is the place of life, the principle and source of the veritable soul, and of intelligence.

MATTER IS NON-BEING, AND CAN NOT BE ANYTHING ACTUAL.

4. All the other objects (the sense-objects), which are something potentially, are also actually something else, which, in regard to the First, may be said to be potential existence. As to matter, which exists potentially in all beings, how could it actually be some of these beings? Evidently, it would then no longer be all beings potentially. If matter be none of the beings, it necessarily is not a being. If it be none of the beings, how could it actually be something? Consequently, matter is none of the beings that in it “become.” But might it not be something else, since all things are not in matter? If matter be none of the beings which are therein, and if these really are beings, matter must be non-being. Since, by imagination, it is conceived as something formless, it could not be a form; as being, it could not be counted among the forms; which is an additional reason why it should be considered as non-being. As matter, therefore, is no “being” neither in respect of beings, nor of forms, matter is non-being in the highest degree. Since matter does not possess the nature of veritable beings, and since it cannot even claim a place among the objects falsely called beings (for not even like these is matter an image of reason), in what kind of being could matter be included? If it cannot be included in any, it can evidently not be something actually.

ARISTOTLE SAID, MATTER IS NOTHING REAL ACTUALLY, BUT ONLY POTENTIALLY.

5. If this be so, what opinion shall we form of matter? How can it be the matter of beings? Because matter potentially constitutes the beings. But, since matter already exists potentially, may we not already say that it exists, when we consider what it is to be? The being of matter is only what is to be; it consists of what is going to be; therefore matter exists potentially; but it is potentially not any determinate thing, but all things. Therefore, being nothing by itself, and being what it is, namely, matter, it is nothing actually. If it were something actually, what it would actually be would not be matter; consequently, matter would no longer be absolutely matter; it would be matter only relatively, like metal. Matter is, therefore, non-being; it is not something which merely differs from being, like movement, which relates to matter because it proceeds from matter, and operates in it. Matter is denuded and despoiled of all properties; it can not transform itself, it remains ever what it was at the beginning, non-being. From the very being it actually was no being, since it had withdrawn from all beings, and had never even become any of them; for never was it able to keep a reflection of the beings whose forms it ever aspired to assume. Its permanent condition is to trend towards something else, to exist potentially in respect of the things that are to follow. As it appears where ends the order of intelligible beings, and as it is contained by the sense-beings which are begotten after it, it is their last degree. Being contained in both intelligible and sense-things, it does not actually exist in respect of either of these classes of beings. It exists only potentially; it limits itself to being a feeble and obscure image, which can not assume any form. May we not thence conclude that matter is the image actually; and consequently, is actually deception? Yes, it truly is deception, that is, it is essentially non-being. If then matter actually be non-being, it is the highest degree of non-being, and thus again essentially is non-being. Since non-being is its real nature, it is, therefore, far removed from actually being any kind of a being. If it must at all be, it must actually be non-being, so that, far from real-being, its “being” (so to speak) consists in non-being. To remove the deception of deceptive beings, is to remove their “being.” To introduce actuality in the things which possess being and essence potentially, is to annihilate their reason for being, because their being consists in existing potentially.

ETERNAL MATTER EXISTS ONLY POTENTIALLY.

Therefore, if matter were to be retained as unchangeable, it would be first necessary to retain it as matter; evidently, it will be necessary to insist that it exists only potentially, so that it may remain what it essentially is; the only alternative would be to refute the arguments we have advanced.
