I have argued that even if time travel is metaphysically possible, there are some things a time traveler would not be able to do. I reply here to critics who have argued that my account entails fatalism about the past or entails that the time traveler is unfree or that she is bound by “strange shackles.” My argument does not entail any sort of fatalism. The time traveler is able to do many of the things that everyone else can do (...) and is as free as any non-time-traveler. The time traveler is constrained only as we all are by the laws of nature. My argument shows only how strangely those constraints must operate if those laws permit time travel. (shrink)

Traditional expressivists want to preserve a contrast between the representational use of declarative sentences in descriptive domains and the non-representational use of declarative sentences in other areas of discourse. However, expressivists have good reasons to endorse minimalism about representational notions, and minimalism seems to threaten the existence of such a bifurcation. Thus, there are pressures for expressivists to become global anti-representationalists. In this paper I discuss how to reconstruct in non-representationalist terms the sort of bifurcation traditional expressivists were after. My (...) proposal is that the relevant bifurcation can be articulated by appeal to the contrast between relativistic and non-relativistic assertoric practices. I argue that this contrast, which can be specified without appeal to representational notions, captures the core intuitions behind the expressivist bifurcation. (shrink)

Many defenders of the possibility of time travel into the past also hold that such time travel places no restrictions on what said time travelers can do. Some hold that it places at least a few restrictions on what time travelers can do. In attempting to resolve this dispute, I reached a contrary conclusion. Time travelers to the past cannot do other than what they in fact do. Using a very weak notion of can, I shall argue that the correspondingly (...) strong cannot do otherwise applies in the case of backwards time travel. I defend this result from objections. (shrink)

In this chapter I articulate the threat that time travel to the past allegedly poses to the free will of the time traveler, and I argue that on the traditional way of thinking about free will, the incompatibilist about time travel and free will wins the day. However, a residual worry about the incompatibilist view points the way toward a novel way of thinking about free will, one that I tentatively explore toward the end of the chapter.
