Moral error theorists often respond to the epistemic companions in guilt strategy by adopting the Disparity Response: reject the putative parity between moral and epistemic reasons and claim that though the former are irreducibly normative, the latter aren’t. I argue such a response fails. Expanding on Das’ Australas J Philos 95:58–69, work I present a master argument against Disparity Responses: the arguments moral error theorists use to advance their conceptual claim apply in the epistemic domain also. This prohibits the error (...) theorist from adopting epistemic reductionism. I use Jonas Olson’s work as exemplary of moral error theory. I demonstrate that Olson’s argument that the rhetorical authority of moral claims is best explained by the error theorist’s conceptual claim applies equally in the epistemic case. Olson attempts to avoid this by claiming that epistemic claims are reducible to claims about whether our doxastic attitudes live up to their functions. There are two problems with Olson’s argument. Firstly, functional reasons are a species of a common genus – standards reasons – and since Olson’s authority argument against moral reductionism applies to standards reasons, it applies to functional reasons. Secondly, Olson’s claim that we cannot also cast moral reasons as functional is under-supported. I suggest that there is plausible evidence that we can and undermine his arguments against this claim. I do not argue that the epistemic companions in guilt strategy demonstrates the falsity of moral error theory. Rather, I argue that the Disparity Response to the epistemic companions in guilt strategy fails. (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)

Arguments for some controversial positions in metaethics—typically moral scepticism or the moral error theory—are sometimes thought to overreach. They appear to entail sceptical or error‐theoretic views about non‐moral branches of thought in a sense that is costly or implausible. If this is true, those metaethical arguments should be rejected. This is the companions in guilt strategy in metaethics. In this article, the contemporary use of the companions in guilt strategy is explored and assessed. The methodology of the strategy is discussed, (...) and criteria for assessing specific instances of its use are identified. Prominent instances of its use in the contemporary literature are then examined. The focus is on those that take (a) epistemic judgment, (b) prudential judgment, and (c) mathematical judgment as “companions,” with a view to undermining the moral error theory and moral scepticism, respectively.

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.

Companions in guilt arguments respond to moral error theory by pointing out that its philosophical rationale mandates the rejection of all categorical normative reasons, including epistemic reasons. A number of philosophers have recently been engaging in a dialogue about the strength of this argumentative strategy and the significance of the criticisms that has been raised against it. In this paper, I identify a specific argument, which I dub the ‘bullet-biting response’ as a crucial element in some recent attacks on the (...) CGA. I assess five objections to the bullet-biting response and conclude that only the fifth poses a significant problem. Specifically, I argue that the proponent of the bullet-biting response is at a dialectical disadvantage in this particular debate. While this disadvantage is not decisive, it has two implications that raise serious concerns for the bullet-biting response. (shrink)

This article is concerned with the interconnection between three arguments: the Moral Explanatory Dispensability Argument, the Epistemic Explanatory Dispensability Argument, and the Companions in Guilt Argument. Silvan Wittwer has recently argued that the Epistemic EDA is self-effacing, whereas the Moral EDA is not. This difference between them is then leveraged by Wittwer to establish that there is a significant disparity between these arguments and that this disparity undermines attempts to use the CGA as a means of refuting the Moral EDA. (...) After explaining the connections between these arguments, I provide three different responses to Wittwer’s analysis. First, I develop a plausible case in favor of the conclusion that the Moral EDA is also self-effacing. Second, I defend the Epistemic EDA from the charge of self-effacement and respond to Wittwer’s assertion that my preferred method of escaping his argument is dialectically inappropriate. Finally, I explain how some arguments recently articulated by Richard Rowland and Ramon Das support my objections to Wittwer’s self-effacement argument. (shrink)

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 instricto sensu, but there can be irreducible ‘normative’ properties which she deems, strictly speaking, to be morally irrelevant. She accepts that there areinstrumentalall things considered oughts, andcategoricalpro tanto oughts (both of which she deems morally irrelevant), but denies that there arecategoricalall 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 first show how one might argue for a mind-independent conception of beauty and artistic merit. I then discuss whether this makes aesthetic judgements suitable to undermine skeptical worries about the existence of mind-independent moral value and categorical reasons.
