Abstract
There is no agreement at all, however, among translators, editors, and scholars, as to what is the number of problems that Aristotle proposes, nor what are the relations of importance among them. The list is given sometimes as fourteen or fifteen, sometimes as six, as nine, as twelve, as eight, and various other numbers. To a reader remembering the meticulous detail with which Aristotle told his students just how to construct topical notebooks and outlines, it seems quite unthinkable that he could have poured this maze of problems over his audience like a bath-attendant, and left them to shift for themselves in discovering its intended organization. A priori, therefore, we would expect some indication within Aristotle's text of the coordination and subordination of his set of problems.
