  For many philosophers, a central philosophical task is to elucidate how we succeed in “creating facts” through our conventions. For instance, how does convention succeed in conferring value upon money or meaning upon linguistic items? Ideally, a satisfying answer to these questions would include both an analysis of what social conventions are and a description of the particular conventions underlying some range of “conventional” facts. Hume’s theory of property and Lewis’s theory of linguistic meaning serve as paradigms here.
