div class=“section” title=“5”> 5 We must explain (i) wherein growth differs from coming-to-be and from ‘alteration’, and ii) what is the process of growing and the sprocess of diminishing in each and all of the things that grow and diminish. Hence our first question is this: Do these changes differ from one another solely because of a difference in their respective ‘spheres’? In other words, do they differ because, while a change from this to that (viz. from potential to actual substance) is coming-to-be, a change in the sphere of magnitude is growth and one in the sphere of quality is ‘alteration’-both growth and ‘alteration’ being changes from what is-potentially to what is-actually magnitude and quality respectively? Or is there also a difference in the manner of the change, since it is evident that, whereas neither what is ‘altering’ nor what is coming-to-be necessarily changes its place, what is growing or diminishing changes its spatial position of necessity, though in a different manner from that in which the moving thing does so? For that which is being moved changes its place as a whole: but the growing thing changes its place like a metal that is being beaten, retaining its position as a whole while its parts change their places. They change their places, but not in the same way as the parts of a revolving globe. For the parts of the globe change their places while the whole continues to occupy an equal place: but the parts of the rowing thing expand over an ever-increasing place and the parts of the diminishing thing contract within an ever-diminishing area. It is clear, then, that these changes-the changes of that which is coming-to- be, of that which is ‘altering’, and of that which is growing-differ in manner as well as in sphere. But how are we to conceive the ‘sphere’ of the change which is growth and diminution? The sphere’ of growing and diminishing is believed to be magnitude. Are we to suppose that body and magnitude come- to-be out of something which, though potentially magnitude and body, is actually incorporeal and devoid of magnitude? And since this description may be understood in two different ways, in which of these two ways are we to apply it to the process of growth? Is the matter, out of which growth takes place, (i) ‘separate’ and existing alone by itself, or (ii) ‘separate’ but contained in another body? Perhaps it is impossible for growth to take place in either of these ways. For since the matter is ‘separate’, either (a) it will occupy no place (as if it were a point), or (b) it will be a ‘void’, i.e. a non-perceptible body. But the first of these alternatives is impossible. For since what comes-to-be out of this 665
