While it is uncontroversial that Kantian constructivism has implications for normative ethics, its status as a metaethical view has been contested. In this article, I provide a characterisation of metaethical Kantian constructivism that withstands these criticisms. I start by offering a partial defence of Sharon Street’s practical standpoint characterisation. However, I argue that this characterisation, as presented by Street, is ultimately incomplete because it fails to demonstrate that the claims of Kantian constructivism constitute a distinctive contribution to metaethics. I then (...) try to complete the practical standpoint characterisation by elaborating on Christine Korsgaard’s suggestion that metaethical Kantian constructivism takes up a position on the source of morality’s normativity.

The conventional wisdom regarding the aims and shortcomings of Kantian constructivism is mistaken. The aim of metaethical constructivism is not to provide a naturalistic account of the objectivity of normative facts by deriving substantive morality from a conception of agency so thin as to be uncontroversial (a task at which it is generally regarded to have failed). Its aim is to explain the “grip” that normative facts have on us—to avoid what I call the problem of normative alienation. So understood, (...) Kantian constructivism faces two problems: that determinate normative facts cannot be derived from agency and that its individualistic conception of agency cannot account for the sociality of morality. I propose and elaborate a social conception of agency that is better able to address the latter problem while still avoiding normative alienation, and evaluate two different strategies for responding to the former problem.

I argue that metaethicists should be concerned with two kinds of alienation that can result from theories of normativity: alienation between an agent and her reasons, and alienation between an agent and the concrete others with whom morality is principally concerned. A theory that cannot avoid alienation risks failing to make sense of central features of our experience of being agents, in whose lives normativity plays an important role. The twin threats of alienation establish two desiderata for theories of normativity; (...) however, I argue that they are difficult to jointly satisfy. (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 and ) as non-moral, can avoid this problem. (shrink)

In section 1 we present moral constructivism as a metaphysical project which grounds moral norms in the attitude of valuing by rational agents. In section 2 we establish that Kantian Constructivism – opposed to Humean Constructivism – seeks objective and universal moral norms through a process of rational construction and ratification of norms that does not draw on any kind of subjective attitude of valuing. In section 3 we explore whether Kant is a moral constructivist or moral realist, arguing that (...) he might be read as a proto-moral constructivist whose formulas impose standards of correctness upon our moral judgments, from which we formulate moral norms as necessary facts of reason. In section 4 we argue that: 1) vulnerabilities have moral relevance which adds merit to the project of finding objective moral norms, and 2) the inclusion of vulnerabilities as empirical contingencies is compatible with Kantian Constructivism. We do so by considering vulnerabilities a constitutive aspect of finite rational agents which must, therefore, be implied and considered in the process of moral construction. (shrink)

Humean constructivists object to Kantian constructivism that by endorsing the constitutivist strategy, which grounds moral obligations in rational agency, this position discounts the impact of cont...

Constructivism in ethics is the view that insofar as there are normative truths, for example, truths about what we ought to do, they are in some sense determined by an idealized process of rational deliberation, choice, or agreement. As a “first-order moral account”--an account of which moral principles are correct-- constructivism is the view that the moral principles we ought to accept or follow are the ones that agents would agree to or endorse were they to engage in a hypothetical (...) or idealized process of rational deliberation. As a “metaethical account” – an account of whether there are any normative truths and, if so, what they are like – constructivism holds that there are normative truths. These truths are not fixed by facts that are independent of the practical standpoint, however characterized; rather, they are constituted by what agents would agree to under some specified conditions of choice. In working to provide a more precise definition of constructivism in metaethics, the focus of this entry, one faces two main difficulties. The first difficulty is that constructivism comes in several varieties, each of which claims a different niche within metaethics, and some claim no space at all. The second difficulty concerns where to place constructivism on the metaethical map in relation to realism and anti-realism. These are terms of art, and it is highly contested which views count as realist and which as antirealist. These two difficulties will be addressed in what follows by focusing on the distinctive questions that constructivist theories are designed to answer. Section §1 defines the scope of constructivism in ethics, in contrast to constructivism in political theory. Sections §§2-5 illustrate the main varieties of metaethical constructivism, which are designed to account for the nature of normative truths and practical reasons. Section §6 presents the main varieties of constructivist accounts of the justification of moral judgments of right and wrong. Section §7 discusses the metaethical status of constructivism, and its distinctive import. (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)
