Habitus diminuuntur, sicut et augentur, quia sicut ex eadem causa augentur ex qua generantur, ita ex eadem causa diminuuntur ex qua corrumpuntur.
Habits diminish, just as they increase, because since they increase through the same cause as that which engenders them, so too they diminish by the same cause as that which corrupts them.
Quaedam diminutio essentiae habitus non habet principium ab habitu, sed a participante.
A certain decrease in the essence of a habit has its origin, not in the habit, but in its subject.
Habitus secundum se consideratus, est forma simplex, et secundum hoc non accidit ei diminutio, sed secundum diversum modum participandi, qui provenit ex indeterminatione potentiae ipsius participantis, quae scilicet diversimode potest unam formam participare, vel quae potest ad plura vel ad pauciora extendi.
A habit, considered in itself, is a simple form. It is not thus that it is subject to decrease, but according to the different ways in which its subject participates in it. This is due to the fact that the subject's potentiality is indeterminate, through its being able to participate a form in various ways, or to extend to a greater or a smaller number of things.
