In this paper I defend what I call the argument from epistemic reasons against the moral error theory. I argue that the moral error theory entails that there are no epistemic reasons for belief and that this is bad news for the moral error theory since, if there are no epistemic reasons for belief, no one knows anything. If no one knows anything, then no one knows that there is thought when (...) they are thinking, and no one knows that they do not know everything. And it could not be the case that we do not know that there is thought when we believe that there is thought and that we do not know that we do not know everything. I address several objections to the claim that the moral error theory entails that there are no epistemic reasons for belief. It might seem that arguing against the error theory on the grounds that it entails that no one knows anything is just providing a Moorean argument against the moral error theory. I show that even if my argument against the error theory is indeed a Moorean one, it avoids Streumer's, McPherson's and Olson's objections to previous Moorean arguments against the error theory and is a more powerful argument against the error theory than Moore's argument against external world skepticism is against external world skepticism.

My aim in this essay is largely defensive. I aim to discuss some problems for moral error theory and to offer plausible solutions. A full positive defense of moral error theory would require substantial investigations of rival metaethical views, but that is beyond the scope of this essay. I will, however, try to motivate moral error theory and to clarify its commitments. Moral error theorists typically accept two claims – (...) one conceptual and one ontological – about moral facts. The conceptual claim is that moral facts are or entail facts about categorical reasons (and correspondingly that moral claims are or entail claims about categorical reasons); the ontological claim is that there are no categorical reasons – and consequently no moral facts – in reality. I accept this version of moral error theory and I try to unpack what it amounts to in Section 2.1 In the course of doing so I consider two preliminary objections: that moral error theory is (probably) false because its implications are intuitively unacceptable (what I call the Moorean objection) and that the general motivation for moral error theory is self-undermining in that it rests on a hidden appeal to norms. The above characterization seems to entail the standard formulation of moral error theory, according to which first-order moral claims are uniformly false. Critics have argued that the standard formulation is incoherent since – by the law of excluded middle – the negation of a false claim is true. Hence if ‘Torture is wrong’ is false, ‘Torture is not wrong’ is true. Contrary to what moral error theorists contend, then, moral error theory seems to carry first-order moral implications that by the theory’s own lights are uniformly false. In Section 3 I suggest a formulation that is consistent with the standard formulation of moral error theory, free of first-order moral implications, and subject to no logical difficulties. In Section 4 I consider and rebut Stephen Finlay’s recent attack on moral error theory. According to Finlay the conceptual claim is false because all moral claims – and indeed all normative claims – are, or should be understood as, relativized to some moral standard or system of ends. Moral error theorists thus attribute to ordinary speakers an error that simply isn’t there. I argue that Finlay’s view has some very implausible implications and that it does not avoid commitment to various forms of error theory. This becomes especially clear when we focus on fundamental moral claims. In Section 5 I consider the worry that error theorists’ rejection of categorical reasons proves too much; in particular, the worry that error theorists’ qualms about categorical reasons apply equally to claims about hypothetical reasons, that is, claims to the effect that there is reason to take the means to one’s ends. In my view error theorists such as Mackie and Joyce have failed to pay due consideration to this problem. What the challenge establishes, I submit, is that error theorists cannot just take for granted that hypothetical reasons are metaphysically unproblematic; they must offer an account of hypothetical reasons that shows that they are. I argue that the only plausible account available to error theorists is one according to which claims about hypothetical reasons reduce to non-normative claims about relations between means and ends.

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.

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.

Moral error theories claim that (i) moral utterances express moral beliefs, that (ii) moral beliefs ascribe moral properties, and that (iii) moral properties are not instantiated. Thus, according to these views, there seems to be conclusive evidence against the truth of our ordinary moral beliefs. Furthermore, many error theorists claim that, even if we accepted moral error theory, we could still in principle keep our first-order moral beliefs. (...) This chapter argues that this last claim makes many popular versions of the moral error theory incompatible with the standard philosophical accounts of beliefs. Functionalism, normative theories of beliefs, representationalism, and interpretationalism all entail that being sensitive to thoughts about evidence is a constitutive feature of beliefs. Given that many moral error theorists deny that moral beliefs have this quality, their views are in a direct conflict with the most popular views about the nature of beliefs. (shrink)

According to moral error theory, moral discourse is error-ridden. Establishing error theory requires establishing two claims. These are that moral discourse carries a non-negotiable commitment to there being a moral reality and that there is no such reality. This paper concerns the first and so-called non-negotiable commitment claim. It starts by identifying the two existing argumentative strategies for settling that claim. The standard strategy is to argue for a relation of conceptual (...) entailment between the moral statements that comprise moral discourse and the statement that there is a moral reality. The non-standard strategy is to argue for a presupposition relation instead. Error theorists have so far failed to consider a third strategy, which uses a general entailment relation that doesn’t require intricate relations between concepts. The paper argues that both entailment claims struggle to meet a new explanatory challenge and that since the presupposition option doesn’t we have prima facie reason to prefer it over the entailment options. The paper then argues that suitably amending the entailment claims enables them to meet this challenge. With all three options back on the table the paper closes by arguing that error theorists should consider developing the currently unrecognised, non-conceptual entailment claim. (shrink)

Recently, companions in guilt strategies have garnered significant philosophical attention as a response to arguments for moral error theory, the view that there are no moral facts and that our moral beliefs are thus systematically mistaken. According to Cuneo (The normative web: an argument for moral realism, Oxford University Press, Oxford, 2007), Das (Philos Q 66:152–160, 2016; Australas J Philos 95(1):58–69, 2017), Rowland (J Ethics Soc Philos 7(1):1–24, 2012; Philos Q 66:161–171, 2016) and others, (...) epistemic facts would be just as metaphysically problematic (or ‘guilty’) as moral facts. But since epistemic error theory is implausible, arguments for moral error theory prove too much and should be rejected. My aim is to argue that the success of this strategy is limited. In particular, the companions in guilt response fails against error-theoretic arguments motivated by concerns about explanatory dispensability, as recently developed by Joyce (The evolution of morality, MIT press, Bradford, 2005) and Olson (Moral error theory: history, critique, defence, Oxford University Press, Oxford, 2014: Ch. 7). To succeed, the response would require a prima facie plausible argument to the effect that epistemic facts are metaphysically dubious because they, too, are explanatorily dispensable. But, as I show, any such argument proves self-effacing: its premise commits us to believing in epistemic facts, while its conclusion forces us to deny their existence. Consequently, companions in guilt strategies don’t offer a panacea against arguments for moral error theory. (shrink)

The paper explores the consequences of adopting a moral error theory targeted at the notion of reasonable convergence. I examine the prospects of two ways of combining acceptance of such a theory with continued acceptance of moral judgements in some form. On the first model, moral judgements are accepted as a pragmatically intelligible fiction. On the second model, moral judgements are made relative to a framework of assumptions with no claim to reasonable convergence (...) on their behalf. I argue that the latter model shows greater promise for an error theorist whose commitment to moral thought is initially serious. (shrink)

Proponents of the epistemic companions in guilt argument argue that we should reject the moral error theory because it entails that there are no epistemic reasons. In this paper, I investigate whether a plausible version of the moral error theory can be constructed that does not entail an error theory about epistemic reasons. I argue that there are no irreducibly normative second-personal reasons even if there are irreducibly normative reasons. And epistemic reasons (...) are not second-personal reasons. In this case, a plausible version of the moral error theory can be constructed that does not entail an error theory about epistemic reasons if facts and claims about morality entail facts and claims about irreducibly normative second-personal reasons. And, as I explain, there is a good case that facts and claims about morality do entail facts and claims about irreducibly normative second-personal reasons. (shrink)

This paper shows how to formulate moral error theories given a contextualist semantics like the one that Angelika Kratzer pioneered, answering the concerns that Christine Tiefensee developed.

Moral abolitionists recommend that we get rid of moral discourse and moral judgement. At first glance this seems repugnant, but abolitionists think that we have overestimated the practical value of our moral framework and that eliminating it would be in our interests. I argue that abolitionism has a surprising amount going for it. Traditionally, abolitionism has been treated as an option available to moral error theorists. Error theorists say that moral discourse and (...) judgement are committed to the existence of moral properties, and that no such properties exist. After error theory is established, abolitionism is one potential way to proceed. However, many error theorists suggest that we retain moral discourse as a sort of fiction. I evaluate some attractions of both fictionalism and abolitionism, arguing that abolitionism is a plausible position. No one doubts that error theorists can be abolitionists. However, what has gone largely undiscussed is that it is open to others to be abolitionists as well. I argue that moral realists of a metaphysically robust sort can and perhaps should be abolitionists. ‘Realist abolitionism’ makes for a surprisingly neat theoretical package, and I conclude that it represents an interesting new option in the theoretical landscape.

In this paper, I distinguish between two error theories of morality: one couched in terms of truth ; the other in terms of justification. I then present two arguments: the Poisoned Presupposition Argument for ET1; and the Evolutionary Debunking Argument for ET2. I go on to show how assessing these arguments requires paying attention to empirical moral psychology, in particular, work on folk metaethics. After criticizing extant work, I suggest avenues for future research.

Moral error theory claims that no moral sentence is (nonvacuously) true. Atheism claims that the existence of evil in the world is incompatible with, or makes improbable, the existence of God. Is moral error theory compatible with atheism? This paper defends the thesis that it is compatible against criticisms by Nicholas Sturgeon.

The moral error theorist claims that moral discourse is irredeemably in error because it is committed to the existence of properties that do not exist. A common response has been to postulate ‘companions in guilt’—forms of discourse that seem safe from error despite sharing the putatively problematic features of moral discourse. The most developed instance of this pairs moral discourse with epistemic discourse. In this paper, I present a new, prudential, companions-in-guilt argument and (...) argue for its superiority over the epistemic alternative. (shrink)

This paper considers whether theism is compatible with moral error theory. This issue is neglected, perhaps because it is widely assumed that these views are incompatible. I argue that this is mistaken. In so doing, I articulate the best argument for thinking that theism and moral error theory are incompatible. According to it, these views are incompatible because theism entails that God is morally good, and moral error theory entails that God (...) is not. I reject this argument. Since it is the best argument for thinking that theism and moral error theory are incompatible, I conclude that these views are compatible: one can coherently accept both views. (shrink)

Nietzsche has sometimes been interpreted as endorsing an error theory about moral judgements. A host of passages provide prima facie reason for such an interpretation. However, the extent of the appropriateness of this interpretation is a matter of dispute. The parameters of his alleged error theory are unclear. This paper reconsiders the evidence for the view that Nietzsche is a moral error theorist and makes the case that Nietzsche defends a local theory (...) about a particular form of “morality,” but that a global error theory about value judgments in general is not established by the textual evidence. This view is defended by considering Nietzsche's affinities with Hume and how they are better harnessed in service of a projectivist error-theoretic reading as opposed to alternatives in the secondary literature (such as noncognitivist readings). Moreover, it explores how Nietzsche can continue to make genuine (that is, nonfictionalist) evaluative judgments by his drawing of a distinction between conventional evaluative practice expressive of herd morality on the one hand and a revisionary evaluative practice available to a small number of “higher types” or “free spirits” on the other.

Moral error theorists think that moral judgments such as ‘stealing is morally wrong’ express truth-apt beliefs that ascribe moral properties to objects and actions. They also think that moral properties are not instantiated. Since moral error theorists think that moral judgments can only be true if they correctly describe moral properties, they think that no moral judgment is true. The belief problem for moral error theory is that (...) this theory is inconsistent with every plausible theory of belief. I argue that moral error theorists can solve the belief problem. My argument is twofold. First, the belief problem rests on a false presupposition about how moral error theorists reason over time. Once we get clear on how would-be error theorists in fact reason towards the error theory and how, once they are error theorists, they subsequently reason about what they should do with their erroneous moral thought and talk, the belief problem evaporates. Second, even if my first argument fails and error theorists do face the belief problem, then we can still identify a plausible theory of belief that is consistent with moral error theory. (shrink)

Traditional arguments for moral error theory are based on identifying a problem with the metaphysics of moral properties. I provide a new argument that is based on the inconsistency of first‐order moral judgments. I illustrate this using impossibility results in population axiology.

Most error theorists want to accept hypothetical reasons but not moral reasons. They do so by arguing that there is no queerness in hypothetical reasons. They can be reduced to purely descriptive claims, about either standards or ordinary standard-independent facts: when I say “I have a reason to take this flight, ” all I say is that “according to certain standards of reasoning, I have a reason to take this flight” or that “I have a desire such that (...) taking this flight is the only way of doing so.” Error theorists who want to accept hypothetical reasons but not moral reasons think that one of these approaches works for hypothetical reasons but neither work for moral reasons. I shall argue that whatever arguments are given for rejecting these approaches in the case of moral reasons are also arguments for rejecting them in the case of hypothetical reasons. (shrink)

Moral error theory has been criticized on formal grounds for lacking a coherent semantics of moral sentences. In this paper, I provide a truthmaker-based semantics of moral sentences that is compatible with moral error theory. The hyperintensional account draws attention to the exact truth- and falsemakers of moral propositions. Error theorists must assume that propositions that have only moral truthmakers have at least one non-moral falsemaker. A central consequence (...) of the discussion is that moral error theory is compatible with a classical logic of moral notions. (shrink)

_ Source: _Volume 13, Issue 4, pp 397 - 402 Moral error theorists and moral realists agree about several disputed metaethical issues.

I introduce a new version of Moral Error Theory, which I call Type-B Moral Error Theory. According to a Type-B theorist there are no facts of the kind required for there to be morality in stricto sensu, but there can be irreducible ‘normative’ properties which she deems, strictly speaking, to be morally irrelevant. She accepts that there are instrumental all things considered oughts, and categorical pro tanto oughts, but denies that there are categorical all (...) things considered oughts on pain of requiring ‘queer’ facts to obtain. I detail the most central motivation of this version of the theory against its more traditional rival, according to which there are no irreducible normative properties at all. The motivation is that it, unlike its rival, can successfully be defended against the notorious charge of self-defeat. (shrink)

I highlight a tension within the moral error theoretic stance. Although I do not show that it is fatal, I believe the tension is problematic. In stating the tension I outline a conception of the common moral background against which it arises. I also discuss aspects of the similar error theories developed by John Mackie and Richard Joyce in order to show the tension at work.

Philosophers should consider a hybrid meta-ethical theory that includes elements of both moral expressivism and moral error theory. Proponents of such an expressivist-error theory hold that all moral utterances are either expressions of attitudes or expressions of false beliefs. Such a hybrid theory has two advantages over pure expressivism, because hybrid theorists can offer a more plausible account of the moral utterances that seem to be used to express beliefs, and (...) hybrid theorists can provide a simpler solution to the Frege-Geach problem. The hybrid theory has three advantages over pure error theory, because hybrid theorists can offer a more plausible account of the moral utterances that seem to be used to express attitudes, hybrid theorists can more easily explain moral motivation, and hybrid theorists can avoid the implausible claim that all moral discourse is radically mistaken. Accordingly, such a hybrid theory should be more attractive than pure expressivism or pure error theory to philosophers who are skeptical about moral facts and truth. (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 (...) class='Hi'>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)

According to moral error theorists, moral talk is like talk about witches. Moral talk commits us to particular normative properties just as witch talk commits u.

We are subject to many different norms telling us how to act, from moral norms to etiquette rules and the law. While some norms may simply be ignored, we live under the impression that others matter for what we ought to do. How can we make sense of this normative authority some norms have? Does it fit into our naturalist worldview? Many philosophers claim it does not. Normativity is conceived to be distinct from ordinary natural properties, making it mysterious. (...) The mystery fuels a radical yet prominent scepticism about the existence of normative properties: if they are too strange to actually exist, there is nothing we ought to do. Some take this to mean, moreover, that nothing is morally right or wrong. We must critically examine the ideas behind these theories, which put both morality and normativity in general on the line. -/- The aim of this thesis is to unravel the mystery of normativity. It uncovers and objects to the influential non-natural conception of it, arguing that we can capture normativity with natural properties. In particular, it explores how the authority of norms can be explained by the commitments of the people subject to them. In connection to this, it challenges the conceptual claim behind the view that all moral judgements are mistaken. Finally, it reveals that treating morality as a mere fiction has revolutionary practical implications. This emphasises the importance of the overall conclusion: we need not conceive of either moral or normative properties as too mysterious to exist. (shrink)

Jonas Olson defends a moral error theory in (2014). I will first argue that Olson is not justified in believing the error theory as opposed to moral nonnaturalism in his own opinion. I will then argue that Olson is not justified in believing the error theory as opposed to moral contextualism either (although the latter is not a matter of his own opinion).

John P. Burgess has remarked that Mackie: “even though he talks of the need to invent morality … does not seem to think that this proposal could be worked into a revisionary meta-ethic”. In the first part of my paper, I argue that Mackie did propose a revisionary meta-ethic (conceptual reformism), and that Mackie was not a preservatist, abolitionist, or semantic pluralist. I also argue that interpreting Mackie as a conceptual reformist enables us to overcome a number of standard objections (...) to his error theory. The upshot is that we should take seriously the idea that Mackie was a conceptual reform moral error theorist. (shrink)

Organizational membership seems to be linked to a more participatory and informed political culture, to foster electoral participation, and to promote positive feelings toward democracy. More recently, the social capital and associative democracy debates have introduced new arguments about the positive effects of associational involvement. However, little attention has been paid to the problems of measuring associational involvement and to their consequences for our theories. This article discusses the various problems of validity and reliability of our measurements of associational membership. (...) It is shown that different questionnaire formats produce substantially different results. The article also addresses the issue of measurement errors and emphasizes the problems they introduce when doing cross-national comparisons. (shrink)

Error theories about morality often take as their starting point the supposed queerness of morality, and those resisting these arguments often try to argue by analogy that morality is no more queer than other unproblematic subject matters. Here, error theory (as exemplified primarily by the work of Richard Joyce) is resisted first by arguing that it assumes a common, modern, and peculiarly social conception of morality. Then error theorists point out that the social nature of morality (...) requires one to act against one's self-interest while insisting on the categorical, inescapable, or overriding status of moral considerations: they argue that morality requires magic, then (rightly) claim that there is no such thing as magic. An alternate eudaimonist conception of morality is introduced which itself has an older provenance than the social point of view, dating to the ancient Greeks. Eudaimonism answers to the normative requirements of morality, yet does not require magic. Thus, the initial motivation for error theory is removed. (shrink)

According to the moral error theory, all moral judgments are false. Until lately, most error theorists were local error theorists; they targeted moral judgments specifically and were less skeptical of other normative areas. These error theorists now face so-called “prudential parity objections”, according to which whatever evidence there is in favor of the moral error theory is also evidence for a prudential error theory. The present paper rejects (...) three prudential parity objections: one based on the alleged irreducible normativity of prudential reasons; another on the lack of a story about the normativity of hypothetical reasons; yet another on the very nature of reasons generally. I argue that these objections leave an important variant of a local moral error theory intact. (shrink)

The paper distinguishes three strategies by means of which empirical discoveries about the nature of morality can be used to undermine moral judgements. On the first strategy, moral judgements are shown to be unjustified in virtue of being shown to rest on ignorance or false belief. On the second strategy, moral judgements are shown to be false by being shown to entail claims inconsistent with the relevant empirical discoveries. On the third strategy, moral judgements are shown (...) to be false in virtue of being shown to be unjustified; truth having been defined epistemologically in terms of justification. By interpreting three recent error theoretical arguments in light of these strategies, the paper evaluates the epistemological and metaphysical relevance of empirical discoveries about morality as a naturally evolved phenomenon.

This dissertation explores arguments and questions related to moral error theory – the idea that morality inevitably involves a fundamental and serious error such that moral judgments and statements never come out true. It is suggested that the truth of error theory remains a non-negligible possibility, and that we for this reason should take a version of moral fictionalism seriously. I begin by defining error theory as the claim that (...) class='Hi'>moral judgments are beliefs with moral propositions as content, moral utterances are assertions of moral propositions, and no positive moral proposition is true. Second, after giving an account of J.L. Mackie’s error theory, I argue that neither Richard Joyce’s nor Jonas Olson’s argument for error theory gives us strong reasons to believe it. According to Joyce, moral discourse presupposes non-institutional desire-transcendent reasons and non-institutional categorical requirements. I challenge this claim by arguing that morality can be understood as an institution, and that the assumption that there are non-institutional moral reasons and requirements can be understood as entering pragmatically into moral conversations. According to Olson, moral discourse involves a commitment to irreducibly normative favoring relations between facts and actions. I challenge this claim by challenging Olson’s response to Stephen Finlay’s argument against absolutist accounts of moral discourse. Third, I discuss two objections to error theory, and argue that neither gives us strong reasons to reject it. According to the first objection, which is suggested by Terence Cuneo, error theory entails epistemic error theory, which has problematic consequences. After indicating some possible responses on part of the epistemic error theorist, I challenge the entailment claim by defending Hilary Kornblith’s account of epistemic reasons as hypothetical reasons. According to the second objection, error theory entails normative error theory, which cannot be believed. Although he does not defend this objection, Bart Streumer has given an argument for the unbelievability claim. I challenge Streumer’s argument by suggesting that we might have hypothetical reasons to believe normative error theory and that, properly understood, Streumer’s conclusion is not as radical as it may first appear. Fourth, I discuss what practical implications the discovery that error theory is true would have for first-order moral thinking and discourse. I argue that if this practice is overall non-morally valuable to us, we ought to revise engagement in it on the model of role-playing in live action role-playing games if we find out that error theory is true. Some have claimed that Richard Joyce’s fictionalism encounters problems. I argue that by incorporating the suggestion that engagement in revised moral practice is modeled on role-playing, fictionalism can escape these problems and preserve the benefits of first-order moral practice.

This article is a response to critical articles by Daan Evers, Bart Streumer, and Teemu Toppinen on my book Moral Error Theory: History, Critique, Defence. I will be concerned with four main topics. I shall first try to illuminate the claim that moral facts are queer, and its role in the argument for moral error theory. In section 2, I discuss the relative merits of moral error theory and moral (...) contextualism. In section 3, I explain why I still find the queerness argument concerning supervenience an unpromising argument against non-naturalistic moral realism. In section 4, finally, I reconsider the question whether I, or anyone, can believe the error theory. (shrink)

In The Myth of Morality Richard Joyce presents a simple and very influential argument for the truth of moral error theory. In this paper I point out that the argument does not have the form Joyce attributes to it, the argument is not valid in an extensional propositional logic and on the most natural way of explicating the meanings of the involved terms, it remains invalid. I conclude that more explanation is needed if we are to accept (...) this particular argument for moral error theory. (shrink)
