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)

In this collection of essays Onora O'Neill explores and argues for an account of justice that is fundamentally cosmopolitan rather than civic, yet takes serious account of institutions and boundaries, and of human diversity and vulnerability. Starting from conceptions that are central to any account of justice - those of reason, action, judgement, coercion, obligations and rights - she discusses whether and how culturally or politically specific concepts and views, which limit the claims and scope of justice, can be avoided. (...) She then examines the demands and scope of just institutions, arguing that there are good reasons for taking the claims of distant strangers seriously, but that doing so points not to a world without boundaries but to one of porous boundaries and dispersed power. Bounds of Justice will be of interest to a wide range of readers in philosophy, politics and international relations. (shrink)

It is largely agreed that if constructivism contributes anything to meta-ethics it is by proposing that we understand ethical objectivity “in terms of a suitably constructed point of view that all can accept” (Rawls 1980/1999: 307). Constructivists defend this “practical” conception of objectivity in contrast to the realist or “ontological” conception of objectivity, understood as an accurate representation of an independent metaphysical order. Because of their objectivist but not realist commitments, Kantian constructivists place their theory “somewhere in the space between (...) realist and relativist accounts of ethics” (O’Neill 1988: 1). Furthermore, they argue that their practical conception of objectivity succeeds in making sense of certain features of morality, such as its categorical authority and its relation to rational agency, which escape rival theories (Korsgaard 1996b, Korsgaard 2003b). To this extent, constructivism claims a privileged place in meta-ethics. The legitimacy of this claim is widely challenged. Precisely because of its practical conception of objectivity, many – including some constructivists — regard constructivism as a first-order normative theory, rather than as a meta-ethical position, hence not on a par with realism. Some critics object that constructivism fails to offer a distinct meta-ethics because it is structurally incomplete and thus must be combined with a fully-fledged meta-ethics (Hussain and Shah 2006); others argue that it tacitly relies on realism (Timmons 2003; Shafer-Landau 2003; Larmore 2008). Thus far, the debate about the prospects of constructivism as a meta-ethical theory has been driven by the conviction that the case for or against constructivism depends on its ontological commitments. In this chapter, I propose a change in perspective. My aim is to defend constructivism as an objectivist account of practical knowledge. Its defining feature is the claim that practical knowledge is knowledge by principles. Its task is to establish a constitutive relation between knowledge of oneself as a practical subject and knowledge about what one ought to do. By focusing on the issue of practical knowledge I hope to show that the difficulty in situating Kantian constructivism firmly on the meta-ethical map, along with other meta-ethical theories, reflects ambiguities and oscillations about the practical significance of ethics. Even though the term is ambiguous, I retain the qualification “Kantian” for the constructivist theory I outline, and for two reasons. First, while the theory I outline differs from current agnostic or anti-realist variants, it is closer to its origins, since Kant treats practical reason as a cognitive capacity and takes moral judgments to be objective moral cognitions, which importantly differ from other sorts of rational cognitions because they bind us in the first person. Practical cognitions are common knowledge because they are such that all subjects endowed with rationality can arrive at them by reasoning and find them authoritative. Thus understood, Kantian constructivism carves a distinct logical space in the meta-ethical debate that other sorts of constructivism fail to identify. This is the second reason for keeping the qualification “Kantian”. On this formulation, constructivism is antagonistic to non-cognitivist theories denying that moral judgments have cognitive contents, because they deny that there is something to be known; but it is also a rival to cognitivist theories denying that knowledge can be practical in itself. How constructivism differs over the realist theories of practical reason is the least understood aspect of this debate. This essay aims to make the case that practical reason is both discursive and emotional. In contrast to foundational and anti-realist accounts of practical reasoning, it attempts to show that the moral feeling of respect plays a cognitive but non-evidential role in the account of the cognitive and practical powers of reason. The argument proceeds as follows. In section 1, I consider some prominent constructivist arguments against the model of applied knowledge and show that they are driven by non-cognitivist assumptions about the practicality of ethics and the legitimacy of epistemological claims. In section 2, I argue that these arguments do not succeed in disposing of the idea of practical knowledge as incoherent, because they trade on an ambiguity regarding the proper object of practical knowledge. To solve this ambiguity, I turn to Anscombe’s contrast between “practical” and “speculative” knowledge as models for understanding action. I thus suggest that Anscombe’s account of practical knowledge as knowledge of oneself as an agent is an important resource for Kantian constructivism. This finding prompts us to reset the current dispute about the ontological and epistemological commitments of Kantian constructivism, as illustrated in section 3. While constructivism does not postulate any moral ontology prior to reasoning, it attributes to reasoning the cognitive powers to establish a distinctive relation between the agent and her action. The task of sections 4-7 is to account for the distinctive features of Kantian constructivism understood as an objectivist account of practical knowledge. In section 4, I argue that in order for reasoning to accomplish its normative tasks, it should be conceived as a self-legislating activity. I respond to some objections to the idea of self-legislation as the form of rational willing by offering a dialogical view of practical reason. In section 5, I propose a non-standard interpretation of Kant’s argument of “the fact of reason” to show that the constructivist account of self-legislation does not build on realism about value, as its detractors claim. The “basis of construction” is the subjective experience of respect for the self-legislative capacity itself. This moral feeling conveys our awareness of rational agency and shows our responsiveness to the demands of practical reason. It is an emotional mode of practical knowledge of oneself as an agent (in the sense specified in section 2), but not as a mode of moral discernment. In section 6, I show how practical knowledge of oneself as an agent relates to practical knowledge about what one ought to do. I thus account for the relation between respect as emotional moral consciousness and respect as a deliberative constraint. Finally, in section 7, I reply to the objection of subjectivism. I explain how the complex sort of objectivity that Kantian constructivism affords is at the same time more ambitious and more modest than is generally assumed. (shrink)
