Whether right is fittingly divided into natural right and positive right?

Objections

Objection 1 : It would seem that right is not fittingly divided into natural right and positive right. For that which is natural is unchangeable, and is the same for all. Now nothing of the kind is to be found in human affairs, since all the rules of human right fail in certain cases, nor do they obtain force everywhere. Therefore there is no such thing as natural right.
Objection 2 : Further, a thing is called "positive" when it proceeds from the human will. But a thing is not just, simply because it proceeds from the human will, else a man's will could not be unjust. Since then the "just" and the "right" are the same, it seems that there is no positive right.
Objection 3 : Further, Divine right is not natural right, since it transcends human nature. In like manner, neither is it positive right, since it is based not on human, but on Divine authority. Therefore right is unfittingly divided into natural and positive.
