A Deontic Logic for Normative DilemmasAbstract: Standard deontic logic does not tolerate normative conflicts. If we assume that one ought to do A and ought to do B, but cannot do them both, we get a contradiction within deontic logic. Philosophers who deny that there could be genuine moral dilemmas treat this fact as the proof that dilemmas are logically impossible. At the same time, the advocates of the possibility of moral dilemmas propose to reject or restrict standard deontic principles. What consequences does it have for the resulting logic? Some of them are too strong because they contain the theorem of normative triviality or “deontic explosion,” which says that if there is any case of normative conflict, then everything is obligatory. On the other hand, some of them are too weak, since they are not able to validate more important deontic inferences especially the Smith Argument. Lou Goble introduces three criteria of adequacy that any deontic logic should meet if it is to accommodate normative conflicts successfully. First, I present these conditions and then I introduce a new logic of ought that fully meets all of them.
