universal problems. Again, we must look to genera dividing according to species, as far as to individuals, as we observed before, for whether a thing appears present with every, or with none, (the opponent) must be required by him, who has adduced many things, to acknowledge universally, or to bring an objection, in what thing it is not so. Besides, in what things it is possible to define accident, whether in species or in number, it must be considered, if no one of these is present, as that time is not moved, and that neither is it motion, having enumerated how many species of motion there are, since if not one of these is present with time, it is evidently not moved, neither is it motion. Likewise also, (if we wish to show) that the soul is not number, (we must prove) by division, every number is either odd or even, as, if the soul is neither odd nor even, it is clearly not number.
For accident then we must argue through such (places) as these, and in such a manner.
