Whether any habit is from nature?

Objections

Objection 1 : It would seem that no habit is from nature. For the use of those things which are from nature does not depend on the will. But habit "is that which we use when we will," as the Commentator says on De Anima iii. Therefore habit is not from nature.
Objection 2 : Further, nature does not employ two where one is sufficient. But the powers of the soul are from nature. If therefore the habits of the powers were from nature, habit and power would be one.
Objection 3 : Further, nature does not fail in necessaries. But habits are necessary in order to act well, as we have stated above (Question [49], Article [4]). If therefore any habits were from nature, it seems that nature would not fail to cause all necessary habits: but this is clearly false. Therefore habits are not from nature.
