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)

Do university ethics classes influence students’ real-world moral choices? We aimed to conduct the first controlled study of the effects of ordinary philosophical ethics classes on real-world moral choices, using non-self-report, non-laboratory behavior as the dependent measure. We assigned 1332 students in four large philosophy classes to either an experimental group on the ethics of eating meat or a control group on the ethics of charitable giving. Students in each group read a philosophy article on their assigned topic and optionally (...) viewed a related video, then met with teaching assistants for 50-minute group discussion sections. They expressed their opinions about meat ethics and charitable giving in a follow-up questionnaire (1032 respondents after exclusions). We obtained 13,642 food purchase receipts from campus restaurants for 495 of the students, before and after the intervention. Purchase of meat products declined in the experimental group (52% of purchases of at least $4.99 contained meat before the intervention, compared to 45% after) but remained the same in the control group (52% both before and after). Ethical opinion also differed, with 43% of students in the experimental group agreeing that eating the meat of factory farmed animals is unethical compared to 29% in the control group. We also attempted to measure food choice using vouchers, but voucher redemption rates were low and no effect was statistically detectable. It remains unclear what aspect of instruction influenced behavior. (shrink)

Moral error theorists face the so-called “now-what problem”: what should we do with our moral judgments from a prudential point of view if these judgments are uniformly false? On top of abolitionism and conservationism, which respectively advise us to get rid of our moral judgments and to keep them, three revisionary solutions have been proposed in the literature: expressivism, naturalism, and fictionalism. In this paper, I argue that expressivism and naturalism do not constitute genuine alternatives to abolitionism, of which they (...) are in the end mere variants—and, even less conveniently, variants that are conform to the very spirit of abolitionism as formulated by its proponents. The main version of fictionalism, by contrast, provides us with a recommendation to which abolitionists cannot consistently subscribe. This leaves us with only one revisionary solution to the now-what problem. (shrink)

Moral judgments attempt to describe a reality that does not exist, so they are all false. This troubling view is known as the moral error theory. Christopher Cowie defends it against the most compelling counter-argument, the argument from analogy: Cowie shows that moral error theory does not compromise the practice of making epistemic judgments.

This book provides a novel formulation and defence of moral error theory. It also provides a novel solution to the so-called now what question; viz., the question what we should do with our moral thought and talk after moral error theory. The novel formulation of moral error theory uses pragmatic presupposition rather than conceptual entailment to argue that moral judgments carry a non-negotiable commitment to categorical moral reasons. The new answer to the now what question is pragmatic presupposition substitutionism: we (...) should substitute our current moral judgments, which pragmatically presuppose the existence of categorical moral reasons with ‘schmoral’ judgments that pragmatically presuppose the existence of a specific class of prudential reasons. These are prudential reasons that, when we act on them, contribute to the satisfaction of what the author calls ‘the fundamental desire’; namely, the desire to live in a world with mutually beneficial cooperation.

This paper is about conceptual engineering. Specifically, it discusses a common objection to CE, which I call the Discontinuity Objection. According to the Discontinuity Objection, CE leads to problematic discontinuities in subject and/or inquiry – making it philosophically uninteresting or irrelevant. I argue that a conceptual engineer can dismiss the Discontinuity Objection by showing that the pre-engineering concept persists through the proposed changes. In other words, the Discontinuity Objection does not apply if the proposal involves identity-preserving changes. Two existing views (...) on identity-preserving changes are considered and rejected. I then argue that an identity-preserving conceptual change is one that allows the concept to continue to perform its function. A concept’s function is its job, its point and purpose, its role in a conceptual repertoire. In a slogan: Preserve a concept’s function, and you preserve the concept itself; preserve the concept, and you preserve the subject. The paper concludes by discussing some implications of this view.

In The Myth of Morality, Richard Joyce argues that moral discourse is hopelessly flawed. At the heart of ordinary moral judgements is a notion of moral inescapability, or practical authority, which, upon investigation, cannot be reasonably defended. Joyce argues that natural selection is to blame, in that it has provided us with a tendency to invest the world with values that it does not contain, and demands that it does not make. Should we therefore do away with morality, as we (...) did away with other faulty notions such as witches? Possibly not. We may be able to carry on with morality as a 'useful fiction' - allowing it to have a regulative influence on our lives and decisions, perhaps even playing a central role - while not committing ourselves to believing or asserting falsehoods, and thus not being subject to accusations of 'error'.

The possibility that nothing really matters can cause much anxiety, but what would it mean for that to be true? Since it couldn’t be bad that nothing matters, fearing nihilism makes little sense. However, the consequences of belief in nihilism will be far more dramatic than often thought. Many metaethicists assume that even if nothing matters, we should, and would, go on more or less as before. But if nihilism is true in an unqualified way, it can’t be the case (...) that we should go on as before. And given some plausible assumptions about our psychology, it’s also unlikely that we would go on as before: belief in nihilism will lead to loss of evaluative belief, and that will lead to loss or deflation of our corresponding subjective concerns. Now if nothing matters, then this consequence also wouldn’t matter. But this consequence will be extremely harmful if we believe in nihilism but things do matter, an asymmetry that gives us, in Pascalian fashion, pragmatic reasons not to believe in nihilism, and reasons not to try to find out whether it is really true.

Moral error theorists hold that morality is deeply mistaken, thus raising the question of whether and how moral judgments and utterances should continue to be employed. Proposals include simply abolishing morality, adopting some revisionary fictionalist stance toward morality, and conserving moral judgments and utterances unchanged. I defend a fourth proposal, namely revisionary moral expressivism, which recommends replacing cognitivist moral judgments and utterances with non-cognitivist ones. Given that non-cognitivist attitudes are not truth apt, revisionary expressivism does not involve moral error. Moreover, (...) revisionary expressivism has the theoretical resources to retain many of the useful features of morality, such as moral motivation, moral disagreement, and moral reasoning. Revisionary expressivism fares better than the three major alternatives in both avoiding moral error and preserving these useful features of morality. I also show how this position differs from the “revolutionary expressivism” of Sebastian Köhler and Michael Ridge. (shrink)

David Enoch develops, argues for, and defends a strongly realist and objectivist view of ethics and normativity more broadly. This view--according to which there are perfectly objective, universal, moral and other normative truths that are not in any way reducible to other, natural truths--is familiar, but this book is the first in-detail development of the positive motivations for the view into reasonably precise arguments. And when the book turns to defend Robust Realism against traditional objections, it mobilizes the original positive (...) arguments for the view to help with fending off the objections. (shrink)

In his recent article entitled ‘Can We Believe the Error Theory?’ Bart Streumer argues that it is impossible (for anyone, anywhere) to believe the error theory. This might sound like a problem for the error theory, but Streumer argues that it is not. He argues that the un-believability of the error theory offers a way for error theorists to respond to several objections commonly made against the view. In this paper, we respond to Streumer’s arguments. In particular, in sections 2-4, (...) we offer several objections to Streumer’s argument for the claim that we cannot believe the error theory. In section 5, we argue that even if Streumer establishes that we cannot believe the error theory, this conclusion is not as helpful for error theorists as he takes it to be. (shrink)

Jonas Olson presents a critical survey of moral error theory, the view that there are no moral facts and so all moral claims are false. Part I explores the historical context of the debate; Part II assesses J. L. Mackie's famous arguments; Part III defends error theory against challenges and considers its implications for our moral thinking.

One worry about metaethical expressivism is that it reduces to some form of subjectivism. This worry is enforced by subjectivists who argue that subjectivism can explain certain phenomena thought to support expressivism equally well. Recently, authors have started to suggest that subjectivism can take away what has often been seen as expressivism's biggest explanatory advantage, namely expressivism's ability to explain the possibility of moral disagreement. In this paper, I will give a response to an argument recently given by Frank Jackson (...) to this conclusion that will show that it is false that subjectivism could explain disagreement as well as expressivism.

Research on moral judgment has been dominated by rationalist models, in which moral judgment is thought to be caused by moral reasoning. The author gives 4 reasons for considering the hypothesis that moral reasoning does not cause moral judgment; rather, moral reasoning is usually a post hoc construction, generated after a judgment has been reached. The social intuitionist model is presented as an alternative to rationalist models. The model is a social model in that it deemphasizes the private reasoning done (...) by individuals and emphasizes instead the importance of social and cultural influences. The model is an intuitionist model in that it states that moral judgment is generally the result of quick, automatic evaluations (intuitions). The model is more consistent than rationalist models with recent findings in social, cultural, evolutionary, and biological psychology, as well as in anthropology and primatology. (shrink)

Survey of some recent literature on normativity, including nonreductionist, neo-Aristotelian, neo-Humean, expressivist, and constructivist views.

Provides a comprehensive introduction to the major philosophical theories attempting to explain the workings of language.

John Mackie's stimulating book is a complete and clear treatise on moral theory. His writings on normative ethics-the moral principles he recommends-offer a fresh approach on a much neglected subject, and the work as a whole is undoubtedly a major contribution to modern philosophy.The author deals first with the status of ethics, arguing that there are not objective values, that morality cannot be discovered but must be made. He examines next the content of ethics, seeing morality as a functional device, (...) basically the same at all times but changing significantly in response to changes in the human condition. He sketches a practical moral system, criticizing but also borrowing from both utilitarian and absolutist views. Thirdly, the frontiers of ethics, areas of contact with psychology, metaphysics, theology, law and politcs, are explored.Throughout, his aim is to discuss a wide range of questions that are both philosophical and practical, working within a distinctive version of subjectivism-an "error" theory of the apparent objectivity of values. John Mackie has drawn on the contributions of such classic thinkers as Plato, Aristotle, Hobbes, Hume, Kant and Sidgwick, and on more recent discussions, to produce a thought-provoking account that will inspire both the general reader and the student of philosophy.

Moral error theorists face the now what question. How, if at all, ought they to adjust their moral practice after having discovered the error? Various answers have emerged in the literature, including, but not limited to, revisionary fictionalism, revisionary expressivism, and revisionary naturalism. Recently, François Jaquet has argued that there are only two available answers to the now what question, since every extant answer except revisionary fictionalism collapses into abolitionism. This paper provides a response. First, it argues that revisionary naturalism (...) does not collapse into abolitionism. The argument is that abolitionists can neither utter schmoralist naturalist replacement judgments that contain moral terms nor eliminativist naturalist replacement judgments that do not contain moral terms. This means that abolitionists cannot utter replacement judgments at all. Since revisionary naturalists can utter replacement judgments, their view does not collapse into abolitionism. Second, the paper gives reason to believe that this result extends beyond revisionary naturalism to the other revisionary metaethical theories, and that this is good news for moral error theory.

Alastair Norcross argues that the basic judgments of morality are essentially comparative: alternatives are judged to be better or worse than each other. Notions such as right and wrong are not part of the fundamental subject matter of moral theory, but are constructed in a context-relative fashion out of the basic comparative judgments.

Error theorists hold that, although our first-order moral thought and discourse commits us to the existence of moral truths, there are no such truths. Holding this position in metaethics puts the error theorist in an uncomfortable position regarding first-order morality. When it comes to our pre-theoretic moral commitments, what should the error theorist think? What should she say? What should she do? I call this the ‘Now What’ Problem for error theory. This paper suggests a framework for evaluating different approaches (...) to the ‘Now What’ Problem, and goes on to evaluate the three most common responses to this problem. All three are found to have noteworthy problems. Finally, I present my own solution, and argue that it presents the most appealing solution to the ‘Now What’ Problem. (shrink)

Unbelievable Errors defends an error theory about all normative judgements: not just moral judgements, but also judgements about reasons for action, judgements about reasons for belief, and instrumental normative judgements. This theory states that normative judgements are beliefs that ascribe normative properties, but that normative properties do not exist. It therefore entails that all normative judgements are false. -/- Bart Streumer also argues, however, that we cannot believe this error theory. This may seem to be a problem for the theory. (...) But he argues that it makes this error theory more likely to be true, since it undermines objections to the theory and it makes it harder to reject the arguments for the theory. -/- He then sketches how certain other philosophical theories can be defended in a similar way. He concludes that to make philosophical progress, we need to make a sharp distinction between a theory's truth and our ability to believe it. (shrink)

Bart Streumer argues that it is not possible for us to believe the error theory, where by ‘error theory’ he means the claim that our normative beliefs are committed to the existence of normative properties even though such properties do not exist. In this paper, we argue that it is indeed possible to believe the error theory. First, we suggest a critical improvement to Streumer’s argument. As it stands, one crucial premise of that argument—that we cannot have a belief while (...) believing that there is no reason to have it—is implausibly strong. We argue that for his purposes, Streumer’s argument only requires a weaker premise, namely that we cannot rationally have a belief while believing that there is no reason to have it. Secondly, we go on to refute the improved argument. Even in its weaker form, Streumer’s argument is either invalid or the crucial premise should be rejected. (shrink)

While the meta‐ethical error theory has been of philosophical interest for some time now, only recently a debate has emerged about the question what is to be done if the error theory turns out to be true. This paper argues for a novel answer to this question, namely revolutionary expressivism: if the error theory is true, we should become expressivists. Additionally, the paper explores certain important but largely ignored methodological issues that arise for reforming definitions generally and with a vengeance (...) in the context of a radical error theory about all practical normative judgements, and suggests how these issues can be resolved.
