13. Those who insist that the substrate of things is a quality common to all elements are bound to explain first the nature of this quality; then, how a quality could serve as substrate; how an unextended, immaterial (?) quality could be perceived in something that lacked extension; further, how, if this quality be determinate, it can be matter; for if it be something indeterminate, it is no longer a quality, but matter itself that we seek.
EVEN THIS PRIVATION MIGHT BE CONSIDERED A QUALITY; BUT SUCH A USE OF THE TERM WOULD DESTROY ALL COHERENT REASONING.
Let us grant that matter has no quality, because, by virtue of its nature, it does not participate in a quality of any other thing. What, however, would hinder this property, because it is a qualification in matter, from participating in some quality? This would be a particular and distinctive characteristic, which consists of the privation of all other things (referring to Aristotle)?[307] In man, the privation of something may be considered a quality; as, for instance, the privation of sight is blindness. If the privation of certain things inhere in matter, this privation is also a qualification for matter. If further the privation in matter extend to all things, absolutely, our objection is still better grounded, for privation is a qualification. Such an objection, however, amounts to making qualities and qualified things of everything. In this case quantity, as well as "being," would be a quality. Every qualified thing must possess some quality. It is ridiculous to suppose that something qualified is qualified by what itself has no quality, being other than quality.
BY A PUN BETWEEN "DIFFERENCE" AND "OTHERNESS," PLOTINOS DEFINES THE CHARACTERISTIC OF MATTER AS BEING A DISPOSITION TO BECOME SOMETHING ELSE.
Some one may object that that is possible, because "being something else" is a quality. We would then have to ask whether the thing that is other be otherness-in-itself? If it be otherness-in-itself, it is so not because it is something qualified, because quality is not something qualified. If this thing be only other, it is not such by itself, it is so only by otherness, as a thing that is identical by identity. Privation, therefore, is not a quality, nor anything qualified, but the absence of quality or of something else, as silence is the absence of sound. Privation is something negative; qualification is something positive. The property of matter is not a form; for its property consists precisely in having neither qualification nor form. It is absurd to insist that it is qualified, just because it has no quality; this would be tantamount to saying that it possessed extension by the very fact of its possessing no extension. The individuality (or, property) of matter is to be what it is. Its characteristic is not an attribute; it consists in a disposition to become other things. Not only are these other things other than matter, but besides each of them possesses an individual form. The only name that suits matter is "other," or rather, "others," because the singular is too determinative, and the plural better expresses indetermination.
PRIVATION IS A FORM OF MATTER.
14. Let us now examine if matter be privation, or if privation be an attribute of matter. If you insist that privation and matter are though logically distinct, substantially one and the same thing, you will have to explain the nature of these two things, for instance, defining matter without defining privation, and conversely. Either, neither of these two things implies the other, or they imply each other reciprocally, or only one of them implies the other. If each of them can be defined separately, and if neither of them imply the other, both will form two distinct things, and matter will be different from privation, though privation be an accident of matter. But neither of the two must even potentially be present in the definition of the other. Is their mutual relation the same as that of a stub nose, and the man with the stub nose (as suggested by Aristotle)?[308] Then each of these is double, and there are two things. Is their relation that between fire and heat? Heat is in fire, but fire is not necessarily contained in heat; thus matter, having privation (as a quality), as fire has heat (as a quality), privation will be a form of matter, and has a substrate different from itself, which is matter.[309] Not in this sense, therefore, is there a unity (between them).
PRIVATION IS NONENTITY, AND ADDS NO NEW CONCEPT.
Are matter and privation substantially identical, yet logically distinct, in this sense that privation does not signify the presence of anything, but rather its absence? That it is the negation of beings, and is synonymous with nonentity? Negation adds no attribute; it limits itself to the assertion that something is not. In a certain sense, therefore, privation is nonentity.
