Most discussions in ethics argue that a certain practice or act is morally justified, with any underlying theory taken as supporting a guide to general action by aiding discovery of the objectively and singularly right thing to do. I suggest that this oversimplifies the agent's own experience of the moral dilemma, and I take the recent English case of Diane Pretty's request for assisted suicide as an example. The law refused, despite the obvious sympathy many felt for her. This only appears paradoxical, I suggest, because too much is expected of the concept of justification, and because moral understanding of a particular case is too often reduced to the legalistic search for general justificatory reasons. The starting point should be, I conclude, a full awareness of the phrase "there but for the grace of God go I".
