  Another route out of paradox would be to hold that the clash depicted by dirty hands theorists occurs within morality. Here, the idea might be that morality itself is not entirely coherent or self-consistent. In certain extreme circumstances, one powerful strand in morality comes into conflict with another. Even more clearly, Weber’s distinction between the ethics of ultimate ends and that of responsibility points in this direction. His idea is expressed somewhat opaquely, but he seems to be claiming that there are two strands in morality, or two types of morality, such that one may be applicable to ordinary life, but must yield to the other in matters political, especially those that involve difficult choices in a context of violence. Several passages in Walzer’s discussion tend in this direction. He holds that a morality of rights and a morality of consequences or utility co-exist in our moral outlook in such a way that although rights trump utility in normal circumstances, a “utilitarianism of extremity” rightly overrides the morality of rights in some rare circumstances. As he puts it: in a situation of supreme emergency, “a certain kind of utilitarianism reimposes itself”, this being “the utilitarianism of extremity” set against “a rights normality” (Walzer 2004a, 40).
