Now distinction among forms is twofold: specific and numeric. Specific distinction of habits follows diversity of objects, while numeric distinction follows distinction of subjects. Consequently a habit may receive increase through extending to objects to which it did not extend before: thus the science of geometry increases in one who acquires knowledge of geometrical matters which he ignored hitherto. But this cannot be said of charity, for even the slightest charity extends to all that we have to love by charity. Hence the addition which causes an increase of charity cannot be understood, as though the added charity were presupposed to be distinct specifically from that to which it is added.

It follows therefore that if charity be added to charity, we must presuppose a numerical distinction between them, which follows a distinction of subjects: thus whiteness receives an increase when one white thing is added to another, although such an increase does not make a thing whiter. This, however, does not apply to the case in point, since the subject of charity is none other than the rational mind, so that such like an increase of charity could only take place by one rational mind being added to another; which is impossible. Moreover, even if it were possible, the result would be a greater lover, but not a more loving one. It follows, therefore, that charity can by no means increase by addition of charity to charity, as some have held to be the case.
