 Ross’s contemporary importance to moral philosophy rests on his clarification and defence of a form of pluralistic deontology attempting to avoid the alleged deficiencies of utilitarianism without embracing the alleged excesses of Kantianism. The most distinctive feature of this view is the notion of a prima facie duty or of a consideration counting in favour of or against an act, morally speaking. Ross’s view serves as an important source of inspiration for those dissatisfied with Kantianism and utilitarianism. Ross said little about issues in what we now call practical or applied ethics. He belonged to a group of moral philosophers, including Moore, Prichard and others, for whom it was not important to work out views on contemporary issues or to use moral philosophy to change the world (though see Ross 1929; RG 56–64, for his reflections on punishment; for illuminating discussion of Ross’s view, see Moriarty 2006; Zimmerman 2011). Nevertheless, Ross’s view has seen a resurgence in ethics and applied ethics (Audi 2004; Beauchamp and Childress 2008; Phillips 2019; Stratton-Lake 2011b).
