Fifteen years of work on nonmonotonic logic has certainly increased our understanding of the area. However, given a problem in which nonmonotonic reasoning is called for. it is far from clear how one should go about modeling the problem using the various approaches. We explore this issue in the context on two of the best-known approaches, Reiter's default logic and Moore's autoepistemic logic, as well as two related notions of "only knowing," due to Halpern and Moses and to Levesque. In particular, we return to the original technical definitions given in these papers and examine the extent to which they capture the intuitions they were designed to capture.
