11. (Following the ideas of Aristotle,[301] Plotinos wonders whether some objector) will ask whether the composition of a body requires anything beyond extension and all the other qualities? Yes: it demands a substrate to receive them (as a residence). This substrate is not a mass; for in this case, it would be an extension. But if this substrate have no extension, how can it be a residence (for form)? Without extension, it could be of no service, contributing neither to form nor qualities, to magnitude nor extension. It seems that extension, wherever it be, is given to bodies by matter. Just as actions, effects, times and movements, though they do not imply any matter, nevertheless are beings, it would seem that the elementary bodies do not necessarily imply matter (without extension), being individual beings, whose diverse substance is constituted by the mingling of several forms. Matter without extension, therefore, seems to be no more than a meaningless name.
MATTER AS THE IMAGE OF EXTENSION, CAN YET BE RESIDENCE OF FORM.
(Our answer to the above objection is this:) To begin with, not every residence is necessarily a mass, unless it have already received extension. The soul, which possesses all things, contains them all simultaneously. If it possessed extension, it would possess all things in extension. Consequently matter receives all it contains in extension, because it is capable thereof. Likewise in animals and plants there is a correspondence between the growth and diminution of their magnitude, with that of their quality. It would be wrong to claim that magnitude is necessary to matter because, in sense-objects, there exists a previous magnitude, on which is exerted the action of the forming principle; for the matter of these objects is not pure matter, but individual matter (as said Aristotle).[302] Matter pure and simple must receive its extension from some other principle. Therefore the residence of form could not be a mass; for in receiving extension, it would also receive the other qualities. Matter therefore, is the image of extension, because as it is primary matter, it possesses the ability to become extended. People often imagine matter as empty extension; consequently several philosophers have claimed that matter is identical with emptiness. I repeat: matter is the image of extension because the soul, when considering matter, is unable to determine anything, spreads into indetermination, without being able to circumscribe or mark anything; otherwise, matter would determine something. This substrate could not properly be called big or little; it is simultaneously big and little (as said Aristotle).[303] It is simultaneously extended and non-extended, because it is the matter of extension. If it were enlarged or made smaller, it would somehow move in extension. Its indetermination is an extension which consists in being the very residence of extension, but really in being only imaginary extension, as has been explained above. Other beings, that have no extension, but which are forms, are each of them determinate, and consequently imply no other idea of extension. On the contrary, matter, being indeterminate, and incapable of remaining within itself, being moved to receive all forms everywhere, ever being docile, by this very docility, and by the generation (to which it adapts itself), becomes manifold. It is in this way its nature seems to be extension.
POLEMIC AGAINST MODERATUS OF GADES, FORMS DEMAND A RESIDENCE, VASE, or LOCATION.
12. Extensions therefore contribute to the constitutions of bodies; for the forms of bodies are in extensions. These forms produce themselves not in extension (which is a form), but in the substrate that has received extension. If they occurred in extension, instead of occurring in matter, they would nevertheless have neither extension nor (hypostatic) substance; for they would be no more than reasons. Now as reasons reside in the soul, there would be no body. Therefore, in the sense-world, the multiplicity of forms must have a single substrate which has received extension, and therefore must be other than extension. All things that mingle form a mixture, because they contain matter; they have no need of any other substrate, because each of them brings its matter along with it. But (forms) need a receptacle (a residence), a "vase" (or stand), a location (this in answer to the objection at the beginning of the former section). Now location is posterior to matter and to bodies. Bodies, therefore, presuppose matter. Bodies are not necessarily immaterial, merely because actions and operations are. In the occurrence of an action, matter serves as substrate to the agent; it remains within him without itself entering into action; for that is not that which is sought by the agent. One action does not change into another, and consequently has no need of containing matter; it is the agent who passes from one action to another, and who, consequently, serves as matter to the actions (as thought Aristotle).[304]
NOT EVEN CORPOREITY INHERES IN MATTER WHICH IS REACHED BY BASTARD REASONING.
Matter, therefore, is necessary to quality as well as to quantity, and consequently, to bodies. In this sense, matter is not an empty name, but a substrate, though it be neither visible nor extended. Otherwise, for the same reason, we would be obliged also to deny qualities and extension; for you might say that each of these things, taken in itself, is nothing real. If these things possess existence, though their existence be obscure, so much the more must matter possess existence, though its existence be neither clear nor evident to the senses. Indeed, matter cannot be perceived by sight, since it is colorless; nor by hearing, for it is soundless; nor by smell or taste, because it is neither volatile nor wet. It is not even perceived by touch, for it is not a body. Touch cognizes only body, recognizes that it is dense or sparse, hard or soft, wet or dry; now none of these attributes is characteristic of matter. The latter therefore can be perceived only by a reasoning which does not imply the presence of intelligence, which, on the contrary, implies the complete absence of matter; which (unintelligent reasoning therefore) deserves the name of "bastard" (or, illegitimate) reasoning.[305] Corporeity itself,[306] is not characteristic of matter. If corporeity be a reason (that is, by a pun, a 'form'), it certainly differs from matter, both being entirely distinct. If corporeity be considered when it has already modified matter and mingled with it, it is a body; it is no longer matter pure and simple.
