Philosophus, in praedicamentis, ponit inter quatuor species qualitatis primam, dispositionem et habitum, quia natura est id quod primum consideratur in re.
The Philosopher in the Book of Categories (Categor. vi) reckons disposition and habit as the first species of quality, because nature is the first object of consideration in anything.
In prima specie consideratur et bonum et malum; et etiam facile et difficile mobile, secundum quod aliqua natura est finis generationis et motus.
In the first species we consider both evil and good; and also changeableness, whether easy or difficult, inasmuch as a certain nature is the end of generation and movement.
Unde in V Metaphys. philosophus definit habitum, quod est "dispositio secundum quam aliquis disponitur bene vel male".
And so the Philosopher (Metaph. v, text. 25) defines habit, a "disposition whereby someone is disposed, well or ill"
Et in II Ethic. dicit quod habitus sunt secundum quos ad passiones nos habemus bene vel male.
And in Ethic. ii, 4, he says that by "habits we are directed well or ill in reference to the passions".
Quando enim est modus conveniens naturae rei, tunc habet rationem boni; quando autem non convenit, tunc habet rationem mali.
For when the mode is befitting to the thing's nature, it has the formal aspect of good; and when it is ill-befitting, it has the formal aspect of evil.
Philosophus dicit, in praedicamentis, quod "una species qualitatis est habitus et dispositio".
The Philosopher says in the Book of the Categories (Categor. vi) that "one species of quality is habit and disposition".
