In the second half of this essay, I discuss the robust conception of rationality that lies at the heart of the Kantian version of Rationalist Constructivism – offering some reasons to prefer this conception to the more minimal accounts of rationality associated with Humean views. I then go on to discuss some of the potential metaethical advantages of the resulting form of constructivism.

There has been much recent debate on the question of whether Kant is to be best understood as a moral realist or a moral constructivist. In an attempt to resolve this debate I examine whether moral constructivism is a form of moral idealism, briefly contrast realism and idealism, and draw on work in social ontology to look at the different accounts of moral ontology implicit in realist and constructivist accounts. As a result of this investigation I conclude that Kant is (...) a moral constructivist. (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)

In Political Liberalism, J. Rawls describes a meta-ethical procedure — political constructivism — whereby political theorists formulate political principles by assembling and reworking ideas from the public political culture. To many of his moral realist and moral constructivist critics, Rawls's procedure is simply a recent version of the “popular moral philosophy” that Kant excoriates in the Groundwork for the Metaphysics of Morals. I defend the idea of political constructivism on philosophical and political grounds. I argue that political constructivism is the (...) best available methodology for self-legislating, socially embedded and fallible human beings; then I show that political constructivism may produce principles that could garner the principled assent of Euro-American Muslims such as Taha Jabir Al-Alwani. The article considers how political constructivism might be employed to formulate new political principles for Euro-American societies experiencing and confronting the Islamic revival. [R]. (shrink)

G. A. Cohen and J. Raz object that Constructivism is incoherent because it crucially deploys unconstructed elements in the structure of justification. This paper offers a response on behalf of constructivism, by reassessing the role of such unconstructed elements. First, it argues that a shared conception of rational agency works as a starting point for the justification, but it does not play a foundational role. Second, it accounts for the unconstructed norms that constrains the activity of construction as constitutive norms. (...) Finally, on this basis, it draws a contrast between constructivist and foundational methods of ethics, such as deontology and teleology. (shrink)
