Moral error theory is the doctrine that our first-order moral commitments are pervaded by systematic error. It has been objected that this makes the error theory itself a position in first-order moral theory that should be judged by the standards of competing first-order moral theories :87–139, 1996) and Kramer. Kramer: “the objectivity of ethics is itself an ethical matter that rests primarily on ethical considerations. It is not something that can adequately be contested or confirmed through non-ethical reasoning” [2009, 1]). (...) This paper shows that error theorists can resist this charge if they adopt a particular understanding of the presuppositions of moral discourse. (shrink)

Some philosophers object to moral error theory by arguing that there a parity between moral and epistemic normativity. They maintain that moral and epistemic error theory stand or fall together, that epistemic error theory falls, and that moral error theory thus falls too. This paper offers a response to this objection on behalf of moral error theorists. I defend the view that moral and epistemic error theory do not stand or fall together by arguing that moral error theory can be (...) sustained alongside epistemic expressivism. This unusual combination of theories can be underpinned by differences in the foundational norms that guide moral and epistemic inquiry. I conclude that the problem of epistemic normativity fails to show that it is compulsory for us to reject moral error theory. (shrink)

If beliefs are a map by which we steer, then, ceteris paribus, we should want a more accurate map. However, the world could be structured so as to punish learning with respect to certain topics—by learning new information, one’s situation could be worse than it otherwise would have been. We investigate whether the world is structured so as to punish learning specifically about moral nihilism. We ask, if an ordinary person had the option to learn the truth about moral nihilism, (...) ought she to take it? We argue, given plausible assumptions about ordinary human preferences, she should not. (shrink)

Ronald Dworkin charges that the error theory is a position in first-order moral theory that should be judged by the standards that are appropriately used in evaluating first-order theories. Perl and Schroeder contend that a “presuppositional error theory” can avoid Dworkin’s charge. On the presuppositional view, moral sentences, such as, “It is wrong to torture babies,” have a false presupposition. Perhaps, for example, they presuppose that there are objectively prescriptive moral standards. This proposal can be understood in different ways, depending (...) on one’s view about presupposition. In Perl and Schroeder’s view, the “at issue” proposition expressed by an assertion of can be cleanly distinguished from the presupposed proposition, and the overall content of an assertion of is the set of these two propositions. On an “entanglement view”, the presupposed proposition is entangled with the proposition expressed by an assertion of in such a way that it is not possible to distinguish cleanly between the “at issue” content and the presupposed content. Perl and Schroeder are correct that, on their view, the presuppositional error theory can avoid Dworkin’s charge. On the entanglement view, however, it cannot avoid Dworkin’s charge. Unfortunately, however, I argue, Perl and Schroeder’s view is implausible for independent reasons. Further, I contend, Perl and Schroeder do not have a solid argument against the entanglement view. They also lack a solid argument in favor of the key, controversial thesis that moral sentences presuppose that there are objectively prescriptive moral standards. (shrink)

Moral error theorists argue that moral thought and discourse are systematically in error, and that nothing is, or can ever be, morally permissible, required or forbidden. I begin by discussing how error theorists arrive at this conclusion. I then argue that if we accept a moral error theory, we cannot escape a pressing problem – what should we do next, metaethically speaking? I call this problem the ‘what now?’ problem, or WNP for short. I discuss the attempts others have made (...) to respond to the WNP, and in each case I show that the responses fail to be satisfying. I then propose a new response to the WNP, which I call revolutionary relativism. I define revolutionary relativism, explain why it is preferable to the existing responses to the WNP, and defend it against the most problematic objections I anticipate that opponents might raise. I conclude that revolutionary relativism succeeds where previous WNP responses fail, and that if we accept a moral error theory, we should become revolutionary relativists. (shrink)
