A Kantian quality of will account of excuses

It is a common picture that Kant is committed to an uncompromising account of moral responsibility that leaves no room for excuses. I argue that this picture is mistaken. More specifically, I reconstruct a Kantian quality of will account of excuses according to which an agent is excused for performing a morally wrong (or omitting a morally obligatory) action if and only if the action (or omission) does not manifest a lack of good will on the part of the agent. Based on this Kantian quality of will account of excuses, I explain why agents are often excused in cases that involve physical constraint, unintentional bodily movement, ignorance, coercion or necessity.
