Whether the natural law is a habit?

Objections

Objection 1 : It would seem that the natural law is a habit. Because, as the Philosopher says (Ethic. ii, 5), "there are three things in the soul: power, habit, and passion." But the natural law is not one of the soul's powers: nor is it one of the passions; as we may see by going through them one by one. Therefore the natural law is a habit.
Objection 2 : Further, Basil [*Damascene, De Fide Orth. iv, 22] says that the conscience or "synderesis is the law of our mind"; which can only apply to the natural law. But the "synderesis" is a habit, as was shown in the FP, Question [79], Article [12]. Therefore the natural law is a habit.
Objection 3 : Further, the natural law abides in man always, as will be shown further on (Article [6]). But man's reason, which the law regards, does not always think about the natural law. Therefore the natural law is not an act, but a habit.
