Abstract. Contrastivism about 'ought' holds that 'ought' claims are relativized, at least implicitly, to sets of mutually exclusive but not necessarily jointly exhaustive alternatives. This kind of theory can solve puzzles that face other linguistic theories of 'ought', via the rejection or severe restriction of principles that let us make inferences between 'ought' claims. By rejecting or restricting these principles, however, the contrastivist takes on a burden of recapturing acceptable inferences that these principles let us make. This paper investigates the extent to which a contrastivist can do this.This paper is about deontic reasoning, or reasoning with oughts. This is very plausibly the kind of reasoning deontic logicians aim to formalize. But I am not here directly concerned with formal logical systems. Rather, I am interested in natural language inferences we can make using the English word 'ought'. In particular, I am concerned with whether a particular kind of theory of the meaning of 'ought' can explain some intuitive deontic inferences, which I take to be data that such a theory needs to explain.Insights from deontic logic are relevant for developing and evaluating accounts of natural language deontic reasoning, and vice versa. Thus, a next step in this project would be to explore proposals in deontic logic, to see what they can teach us about analogous issues in natural language deontic reasoning. Unfortunately, though, all I can do here is flag places where this strategy, of drawing on lessons from deontic logic, seems promising. Near the end of the paper, I will suggest that recent work in preference-based deontic logic, in particular, offers an interesting avenue for future development of the picture I develop.
