Constitutivism aims to justify substantial normative standards as constitutive of practical reason. In this way, it can defend the constructivist commitment to avoiding realism and anti-realism in normative disciplines. This metaphysical debate is the perspective from which the nature of the constitutivist justification is usually discussed. In this paper, I focus on a related, but distinct, debate. My concern will not be whether the substantial normative claims asserted by the constructivist have some elements, which are not constructed, but real, given (...) independently from us; instead, my concern will be more narrowly epistemic – whether those claims can be derived from premises, which are normatively less substantial than the normative conclusions themselves. I focus on Korsgaard’s transcendental articulation of the constitutivist argument. I conclude that more work would need to be done, in order for this argument to function as intended. (shrink)

Kant’s formula of universal law says that it is morally impermissible to act on maxims which lead to a contradiction, when universalized. Korsgaard famously argues that we should understand the contradiction involved in Kant’s formula of universal law test as practical contradiction. In her later works, Korsgaard provides an argument for the truth of Kant’s moral law from the principles that are, on her view, constitutive of human agency, including the principle of publicity, the principle of universality and the hypothetical (...) imperative. In this paper I will, first, clarify Korsgaard’s argument, and, then, argue that her argument cannot vindicate Kant’s moral law. More specifically, I will argue that Korsgaard’s principles, contrary to what she aims, fail to occupy a middle ground between agent-neutral and agent-relative morality; for they rest upon an ambiguity in the notion of sharing the ends of other agents. As a result, Korsgaard’s constitutive principles are either implausible, or too weak to be able to ground our ordinary moral obligations. (shrink)

In The Sources of Normativity, Christine Korsgaard argues that in order to avoid the threat of moral skepticism, our moral theories must show how the claims they make about the nature of our actions obligate us to act morally. A theory that can justify the normativity of morality in this way answers what Korsgaard calls “the normative question.” Although Korsgaard claims that only Kantian theories of morality, such as her own, can answer the normative question, I argue that Adam Smith’s (...) sentimentalist moral theory, as presented in The Theory of Moral Sentiments, can answer the normative question as well. As a result, it is possible to respond to the moral skeptic in the way Korsgaard outlines without accepting some of the theoretical drawbacks of Korsgaard’s own moral theory. (shrink)

When it comes to the metaethical task of explaining and making sense of what it is that we are doing while doing ethics, the subject of moral objectivity occupies an important and special place within that task. Thus, it is often agreed that being able to explain and justify the objective features of common moral practice is one of if not the most important task for any metaethical theory to undertake. In this dissertation, I tackle the issue of ethical objectivity (...) on behalf of metaethical constructivism. To be more precise, my aim is to make plausible, strengthen, and defend the constructivist original contribution to contemporary metaethics by developing a novel constructivist account on the objectivity of ethics. While the account that I develop herein presents a novel and independent approach to the subject of moral objectivity on behalf of constructivism, it also places itself between the two other positions within the constructivist camp that openly strive to secure ethical objectivity – namely Kantianism on the one hand, and the more recently developed Humean objectivist view on the other. It is for the latter reason that I call my own view the hybrid view. (shrink)
