Language Isn't the Only Way

In the world of say common knowledge and common belief, we actually have simple finite statements that represent all these meta levels at once. But there is a sort of element of social construction, even so, where say by saying, we have common belief that if you don't contradict me, then we now get to believe that we have common believed that. And in many ways, of course, we often want what are costly signals instead of cheap signals. So I think it matters to us that the person be engaging, really engaging in the ritual and not just fake engaging in it or something.
