Abstract:

In this paper, I present the discussive adaptive logic DLI^r. As is the case for other discussive logics, the intended application context of DLI^r is the interpretation of discussions. What is new about the system is that it does not lead to explosion when some of the premises are self-contradictory. It is argued that this is important in view of the fact that human reasoners are not logically omniscient, and hence, that it may not be evident to discover the inconsistencies in one's beliefs. In addition to this, DLI^r can handle cases in which different participants contradict each other. It is shown that, in both kinds of cases, DLI^r leads to an interpretation of the discussion that is as rich as possible (even though no discussive connectives are introduced).
