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.
