THE MAGNITUDE OF MATTER IS REALLY DERIVED FROM THE SEMINAL REASON.
16. The ("seminal) reason," on approaching matter, and giving it the extension it desired, made of it a magnitude. The "reason" drew from itself the magnitude to give it to the matter, which did not possess it, and which did not, merely on that account, acquire size; otherwise the magnitude occurring within it would be magnitude itself. If we remove form from matter, the substrate that then remains neither seems nor is large (since magnitude is part of form). If what is produced in matter be a certain magnitude, as for instance a man or a horse, the magnitude characteristic of the horse disappears with the form of the horse.[78] If we say that a horse cannot be produced except in a mass of determined size, and that this magnitude remained (when the form of the horse disappeared), we would answer that what would then remain would not be the magnitude characteristic of the horse, but the magnitude of mass. Besides, if this mass were fire or earth, when the form of fire or that of earth disappeared, the magnitude of the fire or of the earth would simultaneously disappear. Matter therefore possesses neither figure nor quantity; otherwise, it would not have ceased being fire to become something else, but, remaining fire, would never "become" fire.[79] Now that it seems to have become as great as this universe, if the heavens, with all they contain were annihilated, all quantity would simultaneously disappear out of matter, and with quantity also the other inseparable qualities will disappear. Matter would then remain what it originally was by itself; it would keep none of the things that exist within it. Indeed, the objects that can be affected by the presence of contrary objects can, when the latter withdraw, keep some trace of them; but that which is impassible retains nothing; for instance, the air, when penetrated by the light, retains none of it when it disappears. That that which has no magnitude can become great is not any more surprising than that which has no heat can become hot. Indeed, for matter to be matter is something entirely different from its being magnitude; magnitude is as immaterial as figure. Of matter such as it really is we should say that it is all things by participation. Now magnitude forms part of what we call all things. As the bodies are composite, magnitude is there among the other qualities, without however being determinate therein. Indeed, the "reason" of the body also contains magnitude.[80] On the contrary, matter does not even contain indeterminate magnitude, because it is not a body.
