Empirical moral psychology is sometimes dismissed as normatively insignificant because it plays no decisive role in settling ethical disputes. But that conclusion, even if it is valid for normative ethics, does not extend to bioethics. First, in contrast to normative ethics, bioethics can legitimately proceed from a presupposed moral framework. Within that framework, moral psychology can be shown to play four significant roles: it can improve bioethicists’ understanding of the decision situation, the origin and legitimacy of their moral concepts, efficient (...) options for implementing decisions, and how to change and improve some parts of their moral framework. Second, metaethical considerations suggest that moral psychology may lead to the radical revision of entire moral frameworks and thus prompt the radical revision of entire moral frameworks in bioethics. However, I show that bioethics must either relinquish these radical implications of moral psychology and accept that there are limits to progress in bioethics based on moral psychology or establish an epistemic framework that guides radical revision.

The aim of this essay is to introduce scholars to recent discussions of early Confucian ethics that intersect with contemporary moral psychology. Given the early Confucian tradition's intense focus on the cultivation of virtue, there are a number of ways in which early Confucian thinkers – as represented in the texts of the Analects, the Mencius, and the Xunzi – fruitfully engaged in a range of topics that are closely connected to live issues in moral psychology. Not only did they (...) anticipate some contemporary debates but explored them from a distinctively Confucian normative worldview, attending especially to the role of the family and ritual practice. This essay seeks to demonstrate that early Confucianism, by integrating a normative vision with empirically grounded observations of human behavior, offers resources for constructively exploring a number of ongoing questions in moral psychology.

In light of recent empirical data, many psychologists and philosophers have turned away from rationalism about moral judgment and embraced sentimentalism. In the process, they have rejected the classical “moral signature” as a way of distinguishing moral from conventional norms in favor of a sentimentalist approach to carving out the moral domain. In this paper, we argue that this sentimentalist turn has been made prematurely. Although we agree that the experiments reveal that the classical approach is flawed, we propose to (...) replace it with an alternative, according to which a norm is moral precisely if it is justifiable to all. This does not hold for most norms based on disgust or loyalty to a particular community. We accommodate the fact that such norms are not merely conventional by introducing a third domain, the domain of ethics. Our proposal reveals that (psychological) rationalism is still a viable option, as a lot of the experimental evidence that features emotions concerns the domain of ethics rather than morality.

Companions in guilt arguments respond to moral error theory by pointing out that its philosophical rationale mandates the rejection of all categorical normative reasons, including epistemic reasons. A number of philosophers have recently been engaging in a dialogue about the strength of this argumentative strategy and the significance of the criticisms that has been raised against it. In this paper, I identify a specific argument, which I dub the ‘bullet-biting response’ as a crucial element in some recent attacks on the (...) CGA. I assess five objections to the bullet-biting response and conclude that only the fifth poses a significant problem. Specifically, I argue that the proponent of the bullet-biting response is at a dialectical disadvantage in this particular debate. While this disadvantage is not decisive, it has two implications that raise serious concerns for the bullet-biting response. (shrink)

The central question for this dissertation is, how do we do moral philosophy well from within a broadly naturalist framework? Its main goal is to lay the groundwork for a methodological approach to moral philosophy that integrates traditional, intuition-driven approaches to ethics with empirical approaches that employ empirical data from biology and cognitive science. Specifically, it explores what restrictions are placed on our moral theorizing by findings in evolutionary biology, psychology, neuroscience, and other fields, and how we can integrate this (...) data while still offering a fully normative account of ethics. To that end, the dissertation explores the methodological assumptions behind both traditional and more empirical or experimental approaches to ethics, to find where these assumptions cannot be properly supported and need to be re-examined. Chapter 1 explores the science-based objections that have been raised to traditional approaches, with a particular focus on questions concerning the reliability of moral intuitions. Chapter 2 examines three fundamental assumptions supporting the empirical approach to moral philosophy, and how those assumptions ultimately do not fit with how we ought to understand the project of ethics. In chapter 3, I discuss the fact/value distinction, and the restrictions that are placed on our moral theorizing by our commitment to this distinction. Chapter 4 offers a defense of ‘companions in guilt’ arguments, and uses these arguments to draw an analogy between moral philosophy and epistemology that will be used to help defend moral philosophy against empirical debunking arguments. Chapter 5 explores the ways in which epistemologists’ methods of incorporating empirical data into their research while maintaining the normativity of their accounts can be adapted to allow moral philosophers to do the same, and brings together the various methodological concerns addressed up to this point to lay out a methodological approach I call empirically-informed moral philosophy.
