This paper considers and argues against old and recent readings of Hume according to which his account of moral judgement is non-cognitivist. In previous discussions of this topic, crucial metaethical distinctions-between sentimentalism and non-cognitivism and between psychological and semantic non-cognitivism-are often blurred. The paper aims to remedy this and argues that making the appropriate metaethical distinctions undermines alleged support for non-cognitivist interpretations of Hume. The paper focuses in particular on Hume's so-called 'motivation argument' and argues that it is a poor (...) basis for non-cognitivist interpretations. While there is textual support for attributing to Hume what may be called 'modally weak' motivational internalism, there is no solid textual support for attributing to him either psychological or semantic non-cognitivism. The paper also challenges briefly some further alleged support for non-cognitivist interpretations. It concludes by offering some positive evidence against such interpretations, namely that Hume appears to hold that there are moral beliefs and moral knowledge. (shrink)

Motivational internalism and externalism – that is, theories about moral motivation – have played central roles in meta‐ethical debate mainly because they have been thought to have implications for the constitutive nature of moral judgements. Thus, internalism and externalism have been adduced in favour of and against various versions of cognitivism and non‐cognitivism. This article aims to question a fundamental presupposition behind such arguments. It has standardly been assumed (i) that if motivational internalism is true then moral judgements must consist (...) of attitudes that cannot be had without the relevant motivation, and (ii) that if motivational externalism is true, then moral judgements must consist of attitudes that one can have without being motivated. Against the background of a recent argument to the effect that the first of these assumptions is false, this article develops a parallel argument against the second. If this argument is correct, then motivational externalism is consistent with moral judgements being attitudes that one cannot have without being motivated. Together with the parallel argument concerning internalism, this means that the meta‐ethical significance of internalism and externalism must be reconsidered. (shrink)

Much in contemporary metaethics revolves around the two positions known as ‘motivational internalism’ and the ‘Humean theory of motivation’. The importance of these positions is mostly due to their role in what is considered to be the most powerful argument for metaethical non-cognitivism: the so-called ‘motivation argument’. In my paper, I want to argue that widely accepted renditions of the MA, such as the rendition recently forwarded by Russ Shafer-Landau, are flawed in two senses. First, they fail to sufficiently distinguish (...) between conceptual claims and empirical psychological claims, thereby somewhat obscuring the status of the argument and its conclusion. Secondly, they start from definitions of motivational internalism that are, in crucial respects, too strong. Motivational internalism is usually formulated as the claim that moral judgements necessarily motivate; as I want to argue, however, the claim that moral judgements potentially motivate is all the motivational internalism a noncognitivist defender of the MA is ever going to need.

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.

Expressivists explain the expression relation which obtains between sincere moral assertion and the conative or affective attitude thereby expressed by appeal to the relation which obtains between sincere assertion and belief. In fact, they often explicitly take the relation between moral assertion and their favored conative or affective attitude to be exactly the same as the relation between assertion and the belief thereby expressed. If this is correct, then we can use the identity of the expression relation in the two (...) cases to test the expressivist account as a descriptive or hermeneutic account of moral discourse. I formulate one such test, drawing on a standard explanation of Moore's paradox. I show that if expressivism is correct as a descriptive account of moral discourse, then we should expect versions of Moore's paradox where we explicitly deny that we possess certain affective or conative attitudes. I then argue that the constructions that mirror Moore's paradox are not incoherent. It follows that expressivism is either incorrect as a hermeneutic account of moral discourse or that the expression relation which holds between sincere moral assertion and affective or conative attitudes is not identical to the relation which holds between sincere non-moral assertion and belief. A number of objections are canvassed and rejected. (shrink)
