 The notion of a moral consideration’s “strength,” whether put forward as part of a metaphysical picture of how first-order considerations interact in fact or as a suggestion about how to go about resolving a moral conflict, should not be confused with the bottom-line determination of whether one consideration, and specifically one duty, overrides another. In Ross’s example of conflicting prima facie duties, someone must choose between averting a serious accident and keeping a promise to meet someone. (Ross chose the case to illustrate that an “imperfect” duty, or a duty of commission, can override a strict, prohibitive duty.) Ross’s assumption is that all well brought-up people would agree, in this case, that the duty to avert serious harm to someone overrides the duty to keep such a promise. We may take it, if we like, that this judgment implies that we consider the duty to save a life, here, to be stronger than the duty to keep the promise; but in fact this claim about relative strength adds nothing to our understanding of the situation. Yet we do not reach our practical conclusion in this case by determining that the duty to save the boy’s life is stronger. The statement that this duty is here stronger is simply a way to embellish the conclusion that of the two prima facie duties that here conflict, it is the one that states the all-things-considered duty. To be “overridden” is just to be a prima facie duty that fails to generate an actual duty because another prima facie duty that conflicts with it – or several of them that do – does generate an actual duty. Hence, the judgment that some duties override others can be understood just in terms of their deontic upshots and without reference to considerations of strength. To confirm this, note that we can say, “As a matter of fidelity, we ought to keep the promise; as a matter of beneficence, we ought to save the life; we cannot do both; and both categories considered we ought to save the life.”
