Moreover, it is not only impossible that those qualities may be one subject of one quantity; but it is also impossible to say that any quality is the subject of some quantity, so that a distinct quality is the subject of a distinct quantity; for such a plurality of quantities distinct from qualities is altogether superfluous and is granted without necessity.
Again, for the same reason before transubstantiation the substance of the bread was a distinct subject of a quantity distinct from all those quantities whose subjects after transubstantiation are qualities, which is incompatible; for it would then follow that a substance would be a quantum with distinct quantities; for there would be a quantum with one quantity of which there would be an immediate subject and there would be a quantum with other quantities, of which there would be a mediate subject, because with those mediating qualities of which there is a subject.
Again, all, whom I have seen who posit that quantity would be a thing other than substance and quality, hold to the incongruity that two dimensions may be at the same time. But if a substance be the subject of one quantity and a quality be the subject of another quantity, it is necessary to posit that not only two dimensions may be at the same time, but even that more than two may be at the same time; from which it follows that those, who talk in this fashion, do not speak consistently.
Therefore, although according to some it is not inconsistent to posit that distinct quanta are at the same time, which are of a different ground or of the same ground, making however one; nevertheless it seems impossible naturally or through created power that diverse quantities of the same species, most especially those not making a quantity one numerically, are at the same time.
But if each quality could be the subject of a distinct quantity, those quantities could not make a quantity one numerically nor could they be distinguished in species; therefore, they can not be at the same time in the same place; and so it is manifest that each quality is not the subject of a distinct quantity.
