But this, most sapient sir, is not growth, but genesis! For a bag, sack, garment, house, ship, or the like is said to be still coming into existence [undergoing genesis] so long as the appropriate form for the sake of which it is being constructed by the artificer is still incomplete. Then, when does it grow? Only when the basket, being complete, with a bottom, a mouth, and a belly, as it were, as well as the intermediate parts, now becomes larger in all these respects. "And how can this happen?" someone will ask. Only by our basket suddenly becoming an animal or a plant; for growth belongs to living things alone. Possibly you imagine that a house _grows_ when it is being built, or a basket when being plaited, or a garment when being woven? It is not so however. Growth belongs to that which has already been completed in respect to its form, whereas the process by which that which is still _becoming_ attains its form is termed not growth but genesis. That which _is_, grows, while that which _is not_, becomes.
