12. Plato[66] agreed with this, and being persuaded that, by participation, matter does not receive form and shape, as would some substrate that should constitute a composite of things intimately united by their transformation, their mixture, and their common affections; in order to demonstrate the opposite, namely, that matter remains impassible while receiving forms, invented a most apposite illustration of a participation that operates without anything being affected (namely, that engravers, before using dies on the soft wax, clean them carefully). Almost any other kind of illustration would fail to explain how the substrate can remain the same in the presence of forms. While trying to achieve his purpose, Plato has raised many questions; he has besides applied himself to demonstrate that sense-objects are devoid of reality, and that a large part of their hypostatic substance is constituted by appearance. Plato demonstrates the permanence and identity of matter by showing that it is by the figures with which it is endued that matter affects animated bodies, without itself suffering any of their affections. He wishes to convince us that in being endued with these figures, matter undergoes neither affection nor alteration. Indeed, in the bodies that successively assume different figures, we may, relying on analogy, call the change of figures an alteration; but since matter has neither figure nor existence,[67] how could we, even by analogy, call the presence of a figure an alteration? The only sure way of avoiding a misunderstanding in expression is to say that the substrate possesses nothing in the manner it is usually supposed to possess it. How then could it possess the things it contains, unless as a figure? Plato's illustration means that matter is impassible, and that it contains the apparent presence of images which are not really present therein.
PLATO'S FIGURATIVE LANGUAGE MIGHT LEAD TO ERRORS ABOUT HIS REAL OPINIONS.
We must still further preliminarily insist on the impassibility of matter; for by using the usual terms we might be misled into wrongly thinking that matter could be affected. Thus Plato speaks[68] of matter being set on fire, being wetted, and so forth, as if it received the shapes of air or water. However, Plato modifies the statement that "matter receives the shapes of air and water" by the statement that matter "is set on fire and wetted," and he demonstrates that by receiving these shapes it nevertheless has none of its own, and that forms do not more than enter into it. This expression "matter is set on fire" must not be taken literally; it means only that matter becomes fire. Now to become fire is not the same thing as being set on fire; to be set on fire can achieve no more than what is different from fire, than what can be affected; for that which itself is a part of fire could not be set on fire. To insist on the opposite would amount to saying that metal itself formed a statue, or that fire itself spread into matter and set it on fire. The theory that a ("seminal) reason" had approached matter, forces us to question how this reason could have set matter on fire. The theory that a figure had approached matter would imply that that which is set on fire is already composed of two things (matter and a figure), and that these two entities form a single one. Although these two things would form a single one, they would not affect each other, and would act only on other entities. Nor would they even in this case act jointly; for one would effect no more than to hinder the other from avoiding (form). The theory that when the body is divided matter also must be divided, would have to answer the question, How could matter on being divided, escape the affection undergone by the composite (of form and matter)? On such a theory, one might even assert that matter was destroyed, and ask, Since the body is destroyed, why should not matter also be destroyed? What is affected and divided must be a quantity or magnitude. What is not a magnitude cannot experience the same modifications as a body. Therefore those who consider matter affectible would be forced to call it a body.
MATTER AS THE ETERNAL LOCATION OR RESIDENCE OF GENERATION.
13. They would further have to explain in what sense they say that matter seeks to elude form. How can it be said to seek to elude the stones and the solid objects which contain it? For it would be irrational to say that it seeks to elude form at certain times, but not at others. If matter seeks to elude form voluntarily, why does it not elude form continuously? If necessity keep matter (within form), there can be no moment when it would not inhere in some form or other. The reason why matter is not always contained by the same form must not be sought for within matter, but in the forms that matter receives. In what sense then could it be said that matter eludes form? Does it always and essentially elude form? This would amount to saying that matter, never ceasing being itself, has form without ever having it. Otherwise, the statement would be meaningless.[69] (Plato) says that matter is the "nurse and residence of generation." If then matter be the nurse and residence of generation, it is evidently distinct from the latter. Only that which can be affected is within the domain of generation. Now as matter, being the nurse and residence of generation, exists before the latter, it must also exist before any alteration. Therefore to say that matter is the nurse and residence of generation is tantamount to saying that matter is impassible. The same meaning attaches to such other statements as that matter is that in which begotten things appear, and from which they issue,[70] that matter is the (eternal) location, and place (of all generation).[71]
MATTER AS LOCATION OF FORMS REMAINS IMPASSIBLE.
When Plato, rightfully, calls matter "the location of forms," he is not thereby attributing any passion to matter; he only indicates that matters go on in a different manner. How? Since matter, however, by its nature, cannot be any of the beings, and as it must flee from the "being" of all beings, and be entirely different from them—for ("seminal) reasons" are genuine beings—it must necessarily preserve its nature by virtue of this very difference. It must not only contain all beings, but also not appropriate what is their image; for this is that by which matter differs from all beings. Otherwise, if the images that fill a mirror were not transient, and if the mirror remained invisible, evidently we would believe that the things the mirror presents to us existed really. If then there be something in a mirror, that is that which sense-forms are in matter. If in a mirror there be nothing but appearance, then there is nothing in matter but appearance, recognizing that this appearance is the cause of the existence of beings, an existence in which the things that exist always really participate, and in which the things which do not really exist do not participate; for they could not be in the condition where they would be if they existed without the existence of existence in itself.
THE MYTH OF POVERTY AND ABUNDANCE.
14. What! Would nothing exist (in the sense-world) if matter did not exist? Nothing! It is as with a mirror; remove it, and the images disappear. Indeed, that which by its nature is destined to exist in something else could not exist in that thing; now the nature of every image is to exist in something else. If the image were an emanation of the causes themselves, it could exist without being in anything else; but as these causes reside in themselves, so that their image may reflect itself elsewhere, there must be something else destined to serve as location for that which does not really enter into it; something which by its presence, its audacity, its solicitations, and by its indigence, should as it were forcibly obtain (what it desires), but which is deceived because it does not really obtain anything; so that it preserves its indigence, and continues to solicitate (satisfaction[72]). As soon as Poverty exists, it ceaselessly "begs," as a (well-known Platonic) myth tells us;[97] that shows clearly enough that it is naturally denuded of all good. It does not ask to obtain all that the giver possesses; it is satisfied with the possession of some of it, thus revealing to us how much the images that appear in matter are different from real beings. Even the very name of Poverty, which is given to matter, indicates that it is insatiable. When Poverty is said to unite with Abundance, we do not mean that it unites with Existence or Fulness, but with a work of wonderful skill, namely, a thing that is nothing but specious appearance.[74],[98]
