The paper advances a non-orthodox reading of political liberalism’s view of political legitimacy, the view of public political justification that comes with it, and the idea of the reasonable at the heart of these views. Political liberalism entails that full discursive standing should be accorded only to people who are reasonable in a substantive sense. As the paper argues, this renders political liberalism dogmatic and exclusivist at the level of arguments for or against normative theories of justice. Against that background, (...) the paper considers aspects of a more plausible, deeper and more inclusive idea of public political justification that builds on a thinner, potentially cosmopolitan idea of the reasonable. The paper considers what content such an idea may have, and identifies a method of inclusive abstraction through which it may be enriched in content to render it fruitful for the purposes of a justification of principles of political justice. But the move toward more depth and inclusiveness faces constructivism with two challenges. First, inclusivism about the scope of political justification might not be able to avoid dogmatism unless it invokes perfectionist considerations. And second, the authority and appeal of a fruitfully rich idea of the reasonable depends on whether the addressees of political justification already value wide acceptability. (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)

Rainer Forst’s constructivism argues that a right to justification provides a reasonably non-rejectable foundation of justice. With an exemplary focus on his attempt to ground human rights, I argue that this right cannot provide such a foundation. To accord to others such a right is to include them in the scope of discursive respect. But it is reasonably contested whether we should accord to others equal discursive respect. It follows that Forst’s constructivism cannot ground human rights, or justice, categorically. At (...) best, it can ground them hypothetically. This opens the door wide for ethical foundations of human rights. (shrink)

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)
