 One well known approach to deal with the possibility of conflict between deontological duties is to reduce the categorical force of such duties to that of only “prima facie” duties (Ross 1930, 1939). This idea is that conflict between merely prima facie duties is unproblematic so long as it does not infect what one is categorically obligated to do, which is what overall, concrete duties mandate. Like other softenings of the categorical force of deontological obligation we mention briefly below (threshold deontology, mixed views), the prima facie duty view is in some danger of collapsing into a kind of consequentialism. This depends on whether “prima facie” is read epistemically or not, and on (1) whether any good consequences are eligible to justify breach of prima facie duties; (2) whether only such consequences over some threshold can do so; or (3) whether only threatened breach of other deontological duties can do so.
