 In production that results from craft (or art, technê), “the form is in the soul ” (1032b23) of the craftsman. For example, “the craft [of building] is the form [of the house]” (1034a24) and the craft, i.e., the form, is in the understanding, and hence in the soul, of the builder. The builder has in mind the plan or design for a house and he knows how to build; he then “enmatters” that plan or design by putting it into the materials out of which he builds the house. In natural production, the form is found in the parent, where “the begetter is of this same sort as the begotten (not that they are the same thing, certainly, nor one in number, but one in form)—for example, in the case of natural things. For human begets human” (1033b29–31). But in either case, the form pre-exists and is not produced (1033b18).
