 In Locke’s story, one of the things that people wanted to get away from in the state of nature was being subject to others’ incalculable opinions—even when those others were thinking as hard and rigorously as they could about natural law. Your thinking might be different from my thinking, and it might turn out that your view of the relation between your interests and my interests and your property and my interests might be quite different from my view of the matter and quite different again from the view of the next person I came across. The whole point of moving from a state of nature to a situation of positive law was to introduce some predictability into this picture.
