This paper argues that several leading theories of subjunctive conditionals are incompatible with ordinary intuitions about what credences we ought to have in subjunctive conditionals. In short, our theory of subjunctives should intuitively display semantic humility, i.e. our semantic theory should deliver the truth conditions of sentences without pronouncing on whether those conditions actually obtain. In addition to describing intuitions about subjunctive conditionals, I argue that we can derive these ordinary intuitions from justified premises, and I answer a possible worry (...) for my derivation by refuting a subjunctive triviality result modeled on (Lewis 1976). I conclude that the debate over the correct theory of subjunctive conditionals requires settling meta-philosophical questions about the relative value of various virtues of first-order theories of subjunctive conditionals.

An attractive approach to the semantic paradoxes holds that cases of semantic pathology give rise to indeterminacy. What attitude should a rational agent have toward a proposition that it takes to be indeterminate in this sense? Orthodoxy holds that rationality requires that an agent disbelieve such a proposition. I argue that a rational agent should be such that it is indeterminate whether it believes the proposition in question. For rational agents, indeterminacy in the objects of their attitudes will filter up (...) to the attitudes themselves. (shrink)

The following two theses seem both plausible and consistent: in cases where it is indeterminate whether the relevant legal language applies to the relevant set of facts, officials are not bound to decide the case one way rather than the other, but may reason either way; all reasons for action are—in some relevant sense—knowable. In this paper, I point out what I take to be a robust but unacknowledged tension between these two claims. The tension requires some careful teasing out, (...) but the basic idea is that given certain further plausible assumptions concerning law, language, and normativity, the two claims turn out to be inconsistent. In addition to examining the sources of the tension in some detail, I also address several possible objections to my argument and discuss which of the many theses should be rejected. (shrink)
