““If our imagined tribe just is not disposed to cross the boundaries as a matter of inclination, they do not in our sense have an institutional fact. They simply have a disposition to behave in certain ways, and their behavior is just like the case of animals marking the limits of their territory. There is nothing deontic about such markings. The animals simply behave in such and such ways, and “behave” here means they simply move their bodies in specific ways. But if we suppose that the members of the tribe recognize that the line of stones creates rights and obligations, that they are forbidden to cross the line, that they are not supposed to cross it, then we have symbolization. The stones now symbolize something beyond themselves; they function like words. I””
