 A view still held by some researchers within deontic logic and meta-ethics, and particularly popular in the first few decades following the emergence of positivism, was that evaluative sentences are not the sort of sentences that can be either true or false. If that view is correct, we seem to be facing a dilemma. On the one hand, it seems there can be no logic of normative sentences, since logic is the study of what follows from what, and one thing can follow from another only if the things in question are of the sort that can be either true or false. So there can be no deontic logic. On the other hand, some normative sentences do seem to follow from others, and there appear to be logical relations between distinct (possibly logically complex) deontic statements, so there can be deontic logic after all. What to do? This is Jörgensen’s dilemma.
