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 From the very being it actually was no being, since it had withdrawn from all beings, and had never even become any of them; for never was it able to keep a reflection of the beings whose forms it ever aspired to assume.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.
