According to the received view in metaethics, a Neo-Humean theory of rationality entails that there cannot be any objective moral reasons, i.e. moral reasons that are independent of actual desires. In this paper, I argue that there is a version of this theory that is compatible with the existence of objective moral reasons. The key is to distinguish between (i) the process of rational deliberation that starts off in an agent's actual desires, and (ii) the rational principle that an agent (...) employs in such a process. I maintain that it is the latter which explains why it is rational for an agent to have a certain desire, not the former. As a result, there might be two types of principles. The second type of principle leaves room for objective moral reasons. (shrink)

Jürgen Habermas’ discourse theory of morality should be understood, in metaethical terms, as a constructivist theory. All constructivist theories face a Euthyphro-like dilemma arising from how they classify the constraints on their metaethical construction procedures: are they moral or non-moral? Many varieties of Kantian constructivism, such as Christine Korsgaard’s, classify the constraints as moral, albeit constitutive of human reason and agency in general. However, this constitutivist strategy is vulnerable to David Enoch’s ‘shmagency’ objection. The discourse theory of morality, by classifying (...) the constraints on the metaethical construction procedure (principles (D) and (U)) as non-moral, can avoid this problem. (shrink)

Metaethical constructivism is the view that insofar as there are normative truths, they are not fixed by normative facts that are independent of what rational agents would agree to under some specified conditions of choice. The appeal of this view lies in the promise to explain how normative truths are objective and independent of our actual judgments, while also binding and authoritative for us. -/- Constructivism comes in several varieties, some of which claim a place within metaethics while others claim (...) no place within it at all. In fact, constructivism is sometimes defended as a normative theory about the justification of moral principles. Normative constructivism is the view that the moral principles we ought to accept are the ones that agents would agree to or endorse were they to engage in a hypothetical or idealized process of rational deliberation. -/- Metaethical constructivist theories aim to account for the nature of normative truths and practical reasons. They bear a problematic relation to traditional classifications of metaethical theories. In particular, there are disagreements about how to situate constructivism in the realism/antirealism debate. These disagreements are rooted in further differences about the definition of metaethics, the relation between normative and metaethical claims, and the purported methods pertinent and specific to metaethical inquiry. The question of how to classify metaethical constructivism will be addressed in what follows by focusing on the distinctive questions that constructivist theories have been designed to answer. Section 1 explains the origin and motivation of constructivism. Sections 2–4 examine the main varieties of metaethical constructivism. Section 5 illustrates related constructivist views, some of which are not proposed as metaethical accounts of all normative truths, but only of moral truths. Sections 6 and 7 review several debates about the problems, promise and prospects of metaethical constructivism. (shrink)

How should we understand the notion of moral objectivity? Metaethical positions that vindicate morality’s objective appearance are often associated with moral realism. On a realist construal, moral objectivity is understood in terms of mind-, stance-, or attitude-independence. But realism is not the only game in town for moral objectivists. On an antirealist construal, morality’s objective features are understood in virtue of our attitudes. In this paper I aim to develop this antirealist construal of moral objectivity in further detail, and to (...) make its metaphysical commitments explicit. I do so by building on Sharon Street’s version of “Humean Constructivism”. Instead of the realist notion of attitude-independence, the antirealist account of moral objectivity that I articulate centres on the notion of standpoint-invariance. While constructivists have been criticized for compromising on the issue of moral objectivity, I make a preliminary case for the thesis that, armed with the notion of standpoint-invariance, constructivists have resources to vindicate an account of objectivity with just the right strength, given the commitments of ordinary moral thought and practice. In support of this thesis I highlight recent experimental findings about folk moral objectivism. Empirical observations about the nature of moral discourse have traditionally been taken to give prima facie support to moral realism. I argue, by contrast, that from what we can tell from our current experimental understanding, antirealists can capture the commitments of ordinary discourse at least as well as realists can.

According to the standard objection, Kantian constructivism implicitly commits to value realism or fails to warrant objective validity of normative propositions. This paper argues that this objection gains some force from the special case of moral obligations. The case largely rests on the assumption that the moral domain is an eminent domain of special objects. But for constructivism there is no moral domain of objects prior to and independently of reasoning. The argument attempts to make some progress in the debate (...) by defending a robust conception of construction, which names a distinctive view of practical reasoning as transformative. (shrink)

I defend convergentist realism from counterarguments that appeal to apparently deep and widespread moral disagreement. Pace recent claims by antirealists, I first argue that scenarios such as the prominent “Magistrate and the Mob” case betray cognitive defects in subjects, such as partiality, that we would not find in ideal agents. After this, I defend three reasons to expect cross-cultural disagreement on moral cases even if convergentist realism is true. These defusing explanations concern individual and group moral development and the moral (...) models on which agents rely. While developing my defense of moral realism, I aim for comprehensive engagement with responses to arguments by Doris, Plakias, and others that have been dispersed across several related articles.
