Laurel: Modem moral theories must be jettisoned, or at least greatly reworked, because they fail to provide guidance in extreme cases, which are precisely the times when people most need guidance. Miriam: A moral theory, like an overcoat, can be quite useful even if it is not useful in every possible situation. Being useful in a wide variety of common circumstances is all we need from a moral theory. Laurel's and Miriam's statements provide the most support for the claim that they disagree about whether ["a moral theory's adequacy depends on its ability to provide guidance in extreme cases", 'a moral theory developed in the light of extreme cases is unlikely to provide adequate guidance in more usual cases', 'it is preferable to develop a moral theory that provides solutions to all the moral dilemmas that could arise', 'people abandoned earlier moral theories when they encountered dilemmas that those theories did not adequately address']
