Is Agent-Regret Rational?

Bernard Williams claims that we should feel “agent-regret” for bad events we cause but for which we are not blameworthy. Such agent-regret involves no presupposition of fault, yet it also involves a need to personally make amends. This combination suggests that agent-regret, even if virtuous, is inherently irrational. In this paper, I defend agent-regret from attempts to explain it away as a confusion of other attitudes. I argue that the rationality of agent-regret is found in how it makes sense as a response to conflicts that might arise between people through nothing more than bad luck.
