Accordingly charity increases only by its subject partaking of charity more and more subject thereto. For this is the proper mode of increase in a form that is intensified, since the being of such a form consists wholly in its adhering to its subject. Consequently, since the magnitude of a thing follows on its being, to say that a form is greater is the same as to say that it is more in its subject, and not that another form is added to it: for this would be the case if the form, of itself, had any quantity, and not in comparison with its subject. Therefore charity increases by being intensified in its subject, and this is for charity to increase in its essence; and not by charity being added to charity.

Reply Obj. 1: Bodily quantity has something as quantity, and something else, in so far as it is an accidental form. As quantity, it is distinguishable in respect of position or number, and in this way we have the increase of magnitude by addition, as may be seen in animals. But in so far as it is an accidental form, it is distinguishable only in respect of its subject, and in this way it has its proper increase, like other accidental forms, by way of intensity in its subject, for instance in things subject to rarefaction, as is proved in Phys. iv, 9. In like manner science, as a habit, has its quantity from its objects, and accordingly it increases by addition, when a man knows more things; and again, as an accidental form, it has a certain quantity through being in its subject, and in this way it increases in a man who knows the same scientific truths with greater certainty now than before. In the same way charity has a twofold quantity; but with regard to that which it has from its object, it does not increase, as stated above: hence it follows that it increases solely by being intensified.
