What is the ground for distinguishing between habit and disposition, seeing that no differentia of Quality is involved in permanence and non-permanence?
Moreover, no room is left for a differentia by which this Something may be distinguished.
Quality is never a differentia of Quality, any more than Substance is a differentia of Substance, or Quantity of Quantity.
As for the differentia being derived from the same genus as themselves, namely, Quality, and from no other genus, if we proceed on the principle that virtue is bound up with pleasure, vice with lust, virtue again with the acquisition of food, vice with idle extravagance, and accept these definitions as satisfactory, then clearly we have, here too, differentiae which are not qualities.
It remains to decide whether there can be any differentia derived from the genus to which the differentiated thing belongs, or whether it must of necessity belong to another genus?
Virtue and vice are two states differing in quality: the states are qualities, and their differentiae qualities--unless indeed it be maintained that the state undifferentiated is not a quality, that the differentia creates the quality.
