Remorse and Agent-Regret

This article develops and explores the notion of agent-regret. I agree with Bernard Williams that agent-regret has a moral significance not captured by simple regret or by remorse, but argue that its significance does not displace that of remorse. My focus is largely on understanding agent-regret and recognizing the importance of both agent-regret and remorse to philosophy and to a proper understanding of morally good character; but I also suggest that the notion of agent-regret helps to widen our concept of responsibility, lending plausibility to the notion of collection responsibility.
