Moral Responsibility and Time Travel in an Indeterministic World

I have argued against the Principle of Alternative Possibilities using a time travel-based counterexample. Kelly McCormick has responded to my counterexample by arguing that the time travel scenario must be a scenario in which a time traveler’s actions are causally determined; hence, she claims, we should be suspicious of attributing moral responsibility to anyone in such a scenario. In this paper, I respond by arguing that one might be morally responsible in an indeterministic time travel scenario.
