12. What other scheme of analysis of quality could we find, if the above were declared unsatisfactory? Must we distinguish first the qualities of the soul from those of the body, and then analyse the latter according to the senses, relating them to sight, hearing, taste, smell and touch? To begin with, how can the qualities of the soul be divided? Will they be related to the faculty of desire, to anger, or reason? Will they be divided according to their suitable operations, or according to their useful or harmful character? In this case, would we distinguish several ways of being useful or harmful? Should we then likewise divide the properties of the bodies according to the difference of their effects, or according to their useful or harmless character, since this character is a property of quality? Surely; to be useful or harmful seems to be the property of both the quality, and the thing qualified. Otherwise, we should have to seek some other classification. RELATION BETWEEN THE THING QUALIFIED AND THE QUALITY. How can the thing qualified by a quality refer to the quality? This must be studied, because the thing qualified and the quality do not belong to a common kind. If the man capable of boxing be related to the quality, why should not the same quality obtain between the active man and activity? If then the active man be something qualified, "activity" and "passivity" should not be referred to relation. It would seem preferable to relate the active man to the quality if he be active by virtue of a power, for a power is a quality; but if the power be essential, in so far as it is a power, it is not something relative, nor even something qualified. We should not consider that activity corresponds to increase; for the increase, so far as it increases, stands in relation only to the less; while activity is such by itself. To the objection that activity, so far as it is such, is something qualified, it might be answered that, at the same time, as far as it can act on something else, and that it is thus called active, it is something relative. In this case the man capable of boxing and the art of boxing itself must be in relation. For the art of boxing implies a relation; all the knowledge it imparts is relative to something else. As to the other arts, or at least, as to the greater number of other arts, it may, after examination, be said that they are qualities, so far as they give a disposition to the soul; as far as they act, they are active, and, from this standpoint, they refer to something else, and are relative; and besides, they are relative in the sense that they are habituations. ACTIVITY DOES NOT ALTER THE QUALITY.
