In previous work, I defend the following disparity between moral and epistemic facts: whereas moral facts are irreducibly normative, epistemic facts – facts such as that some subject is epistemically justified in believing something – are reducible to facts from some other domain (such as facts about probabilities). This moral-epistemic disparity is significant because it undercuts an important kind of argument for robust moral realism. My defense of epistemic reductionism and of the moral-epistemic disparity has been criticized by Richard Rowland (...) (2013) and by Terence Cuneo and Christos Kyriacou (forthcoming). This paper aims to rebut these criticisms and, more generally, to clarify and strengthen the case for epistemic reductionism and the moral-epistemic disparity. (shrink)

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)

A ‘companions in guilt’ strategy against moral error theory aims to show that the latter proves too much: if sound, it supports an implausible error-theoretic conclusion in other areas such as epistemic or practical reasoning. Christopher Cowie [2016 Cowie, C. 2016. Good News for Moral Error Theorists: A Master Argument Against Companions in Guilt Strategies, Australasian Journal of Philosophy 94/1: 115–30.[Taylor & Francis Online], [Web of Science ®] [Google Scholar]] has recently produced what he claims is a ‘master argument’ against (...) all such strategies. The essence of his argument is that CG arguments cannot work because they are afflicted by internal incoherence or inconsistency. I argue, first, that Cowie's master argument does not succeed. Beyond this, I argue that there is no good reason to think that any such argument—one that purports to identify an internal incoherence in CG arguments—can succeed. Second, I argue that the main substantive area of disagreement between error theorists and CG theorists essentially concerns the conceptual profile of epistemic reasons—specifically, whether they are strongly categorical—not the ontological question of whether such reasons exist. I then develop an argument in favour of the CG theorist's position by considering the moral error theorist's arguments in support of the conceptual claim that moral reasons are strongly categorical. These include, notably, criticisms made by Joyce [2011] and Olson [2014] of Finlay's [2008] ‘end relational’ view of morality, according to which moral reasons are relative to some end or standard, hence not strongly categorical. Examining these criticisms, I argue that, based on what moral error theorists have said regarding the conceptual profile of moral reasons, there is a strong case to be made that moral reasons are strongly categorical if and only if epistemic reasons are.

Moral error theories are often rejected by appeal to ‘companions in guilt’ arguments. The most popular form of companions in guilt argument takes epistemic reasons for belief as a ‘companion’ and proceeds by analogy. I show that this strategy fails. I claim that the companions in guilt theorist must understand epistemic reasons as evidential support relations if her argument is to be dialectically effective. I then present a dilemma. Either epistemic reasons are evidential support relations or they are not. If (...) they are not, then the companions in guilt argument fails. If they are, then a reduction of epistemic reasons to evidential support relations becomes available and, consequently, epistemic reasons cease to be a viable ‘companion’ for moral reasons. I recommend this structure of argument over existing strategies within the literature and defend my claims against recent objections from companions in guilt theorists. (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.

What is the source of epistemic normativity? In virtue of what do epistemic norms have categorical normative authority? According to epistemic teleologism, epistemic normativity comes from value. Epistemic norms have categorical authority because conforming to them is necessarily good in some relevant sense. In this article, I argue that epistemic teleologism should be rejected. The problem, I argue, is that there is no relevant sense in which it is always good to believe in accordance with epistemic norms, including in cases (...) where the matter at hand is completely trivial. Therefore, if epistemology is normative, its normativity won't come from value. (shrink)

Terence Cuneo has recently argued that we have to be committed to the existence of epistemic facts insofar as they are indispensable to theorizing. Furthermore, he argues that the epistemic properties of these facts are inextricably ‘ontologically entangled’ with certain moral properties, such that there exist ‘moral-epistemic’ facts. Cuneo, therefore, concludes that moral realism is true. I argue that Cuneo’s appeal to the existence of moral-epistemic facts is problematic, even granting his argument for the existence of indispensable epistemic facts. I (...) conclude, therefore, that Cuneo’s argument fails to justify moral realism. (shrink)

According to epistemic instrumentalists the normativity of evidence for belief is best explained in terms of the practical utility of forming evidentially supported beliefs. Traditional arguments for instrumentalism—arguments based on naturalism and motivation—lack suasive force against opponents. A new argument for the view—the Argument from Coincidence—is presented. The argument shows that only instrumentalists can avoid positing an embarrassing coincidence between the practical value of believing in accordance with one’s evidence, and the existence of reasons so to believe. Responses are considered (...) and shown to be inadequate. (shrink)

While Richard Joyce’s moral skepticism might seem to be an extreme metaethical view, it is actually far more moderate than it might first appear. By articulating four challenges facing his approach to moral skepticism, I argue that Joyce’s moderation is, in fact, a theoretical liability. First, the fact that Joyce is not skeptical about normativity in general makes it possible to develop close approximations to morality, lending support to moderate moral revisionism over moral error theory. Second, Joyce relies on strong, (...) contentious conceptual and empirical claims in support of his views. Third, Joyce’s evolutionary debunking argument threatens to backfire, generalizing to all normative judgments. Finally, Joyce fails to offer an adequate account of the normativity of desire. Each of these four challenges can be either sidestepped or embraced by radicalizing and defending a global form of normative skepticism. There are thus several ways in which global normative skepticism appears to be in a more robust dialectical position than Joyce’s moral skepticism. Furthermore, I argue, Joyce’s arguments against global normative skepticism are unconvincing. While this discussion is framed in terms of Joyce’s work, its arguments will apply to other moral skeptics who are not also global normative skeptics. The result is an invitation for Joyce and other moral skeptics to leave these problems behind and join the radical camp. (shrink)

One recently popular strategy for avoiding the moral error theory is via a ‘companions in guilt’ argument. I focus on those recently popular arguments that take epistemic facts as a companion in guilt for moral facts. I claim that there is an internal tension between the two main premises of these arguments. It is a consequence of this that either the soundness or the dialectical force of the companions in guilt argument is undermined. I defend this claim via (i) analogy (...) with philosophical debates concerning the indispensability of mathematical objects to natural science, and (ii) discussion of the ‘entanglement’ of epistemic concepts and moral concepts in deliberation. I conclude by proposing a positive view of what kind of argument must be used if moral error theories are to be successfully undermined. (shrink)

It is widely supposed that evolutionary debunking arguments against morality constitute a type of epistemological objection to our moral beliefs. In particular, the debunking force of such arguments is not supposed to depend on the metaphysical claim that moral facts do not exist. In this paper I argue that this standard epistemological construal of EDAs is highly misleading, if not mistaken. Specifically, I argue that the most widely discussed EDAs all make key and controversial metaphysical claims about the nature of (...) morality or the possibility of moral truth that belie their apparently epistemological character. I show that the debunking force of these EDAs derives largely from metaphysical claims about morality and their implications for the possibility of moral reduction, rather than from epistemological worries associated with the existence of an causal/non-moral explanation of our moral judgments. The paper briefly concludes with a dilemma that I believe confronts all EDAs such as those discussed in this paper: either such arguments are unsound, or else they prove too much, debunking our knowledge of science and the external world, as well as morality.

Companions in guilt arguments are widespread in defenses of moral realism and criticisms of error theory. Recently, a number of philosophers have argued that the companions in guilt argument fails because it makes untenable assumptions about the existence of categorical epistemic reasons. In this article, I develop an alternative version of the companions in guilt argument that does not succumb to this criticism, as it begins with the claim that there is a presumptive case in favor of attributing a belief (...) in categorical norms of philosophical argumentation to proponents of the error theory. I then point to an instability in the error-theoretic position and explore the extent to which this instability poses a serious philosophical problem. While this argument has a narrower scope than the traditional companions in guilt arguments, I conclude that it nonetheless poses a significant challenge to any philosophical attempt to deny the categoricity of moral reasons. (shrink)

Christopher Cowie has recently argued that companions in guilt arguments against the moral error theory that appeal to epistemic reasons cannot work. I show that such companions in guilt arguments can work if, as we have good reason to believe, moral reasons and epistemic reasons are instances of fundamentally the same relation.
