Ross divides prima facie duties into derivative and foundational ones, but seems to understand the notion of a derivative prima facie duty in two very different ways. Sometimes he understands them in a non-eliminativist way. According to this understanding, basic prima facie duties ground distinct derivative ones. According to the eliminativist understanding, basic duties do not ground distinct derivative duties, but replace them. On the eliminativist view, discovering that a prima facie duty is derivative is discovering that it is not genuine. The genuine one is the basic one. I argue that Ross is best understood as an eliminativist.

The Right and the Good, a classic of twentieth-century philosophy by the great scholar Sir David Ross, is now presented in a new edition with a substantial introduction by Philip Stratton-Lake, a leading expert on Ross. Ross's book is the pinnacle of ethical intuitionism, which was the dominant moral theory in British philosophy for much of the nineteenth and early twentieth century. Intuitionism is now enjoying a considerable revival, and Stratton-Lake provides the context for a proper understanding of Ross's great work today.

According to one formulation of Scanlon’s contractualist principle, certain acts are wrong if they are permitted by principles that are reasonably rejectable because they permit such acts. According to the redundancy objection, if a principle is reasonably rejectable because it permits actions which have feature F, such actions are wrong simply in virtue of having F and not because their having F makes principles permitting them reasonably rejectable. Consequently Scanlon’s contractualist principle adds nothing to the reasons we have not to act wrongly and is redundant.

Ethical intuitionists are often criticised on the ground that their view makes it possible for an agent to believe that she ought to ? whilst lacking any motive to ?-that is, on the ground that it involves, or implies a form of externalism. I begin by distinguishing this form of externalism (what I call 'belief externalism') from two other forms of ethical externalism-moral externalism, and reasons externalism. I then consider various reasons why one might think that ethical intuitionism is defective in so far as it involves, or implies belief externalism, and argue that these objections are unpersuasive
