This work gives a new argument for ‘Empirical Philosophy of Mathematical Practice’. It analyses different modalities on how empirical information can influence philosophical endeavours. We evoke the classical dichotomy between “armchair” philosophy and empirical/experimental philosophy, and claim that the latter should in turn be subdivided in three distinct styles: Apostate speculator, Informed analyst, and Freeway explorer. This is a shift of focus from the source of the information towards its use by philosophers. We present several examples from philosophy of mind/science (...) and ethics on one side and a case study from philosophy of mathematics on the other. We argue that empirically informed philosophy of mathematics is different from the rest in a way that encourages a Freeway explorer approach, because intuitions about mathematical objects are often unavailable for non-mathematicians. This consideration is supported by a case study in set theory. (shrink)

The debate between proponents and opponents of a role for empirical psychology in ethical theory seems to be deadlocked. This paper aims to clarify the terms of that debate, and to defend a principled middle position. I argue against extreme views, which see empirical psychology either as irrelevant to, or as wholly displacing, reflective moral inquiry. Instead, I argue that moral theorists of all stripes are committed to a certain conception of moral thought—as aimed at abstracting away from individual inclinations (...) and toward interpersonal norms—and that this conception tells against both extremes. Since we cannot always know introspectively whether our particular moral judgments achieve this interpersonal standard, we must seek the sort of self-knowledge offered by empirical psychology. Yet reflective assessment of this new information remains a matter of substantive normative theorizing, rather than an immediate consequence of empirical findings themselves. (shrink)

This paper presents a regress challenge to the selective psychological debunking of moral judgments. A selective psychological debunking argument conjoins an empirical claim about the psychological origins of certain moral judgments to a theoretical claim that these psychological origins cannot track moral truth, leading to the conclusion that the moral judgments are unreliable. I argue that psychological debunking arguments are vulnerable to a regress challenge, because the theoretical claim that ‘such-and-such psychological process is not moral-truth-tracking’ relies upon moral judgments. We (...) must then ask about the psychological origins of these judgments, and then make a further evaluative judgment about these psychological origins… and so on. This chain of empirical and evaluative claims may continue indefinitely and, I will argue, proponents of the debunking argument are in a dialectical position where they may not simply call a halt to the process. Hence, their argument cannot terminate, and its debunking conclusion cannot be upheld. (shrink)

A well-known maxim instructs that justice should be seen to be done. When “seen” is understood in the sense of “observed”, the maxim is easily defended: open court proceedings protect against arbitrary and partial decisions. However, when “seen” is understood in the sense of “seem,” the maxim is more puzzling, since it is not obvious why courts should concern themselves with people's perceptions that justice has been done. This article addresses this issue, with a particular focus on the social and (...) other benefits that result when judges observe procedures that are widely regarded as fair, especially in criminal trials. The article draws on empirical studies in social psychology that show that when legal authorities treat people in ways that accord with “lay” procedural expectations, they are more likely to view the authorities as legitimate, to cooperate with them, and to obey the law out of an internalized sense of obligation. The article explores the moral significance of these empirical findings, arguing that it would be superficial to see them as a recipe for social stability. The deeper truth conveyed by the empirical research is that relating to people in ways that are widely perceived to be fair is a way for authorities to engage people's moral sentiments and to enliven their virtuous capacity to put aside considerations of self-interest so as to do what is right. This dynamic provides a sound moral foundation for courts to concern themselves with perceptions of justice. (shrink)

Jesse Prinz develops a naturalistic metaethical theory with which he purports to sidestep ‘Hume's law’ by demonstrating how, on his theory, in describing what our moral beliefs commit us to we can determine what our moral obligations are. I aim to show that Prinz does not deliver on his prescriptive promise – he does not bridge the is–ought gap in any meaningful way. Given that Prinz goes on to argue that (1) his moral psychology highlights fundamental shortcomings in ‘traditional’ normative (...) ethical theories, (2) that moral progress is possible, despite the relativistic implications of his own position, and (3) that this undermining of the is–ought gap should hold true on any naturalistic metaethical theory, the extent to which his project succeeds becomes significant.

To develop more effective ethics education for cross-cultural and international engineering, a study was conducted to determine what Chinese engineering students have learned and think about ethics. Recent research shows traditional approaches to ethics education are potentially ineffective, but also points towards ways of improving ethical behaviors. China is the world’s most populous country, graduating and employing the highest number of STEM majors, although little empirical research exists about the ethical knowledge and perspectives of Chinese engineering students. When compared to (...) engineering students in the US, Chinese engineering students received less ethics education; the form of the education they did receive stressed virtue ethics or the development of moral character; conceive of ethics in contradistinction to the law, where ethics deals with matters of right and wrong not covered by legality. Based on these findings and research in moral psychology and behavioral ethics, recommendations are made for improving engineering ethics education both in China and abroad. (shrink)

This chapter discusses the philosophical relevance of empirical research on moral cognition. It distinguishes three central aims of normative ethical theory: understanding the nature of moral agency, identifying morally right actions, and determining the justification of moral beliefs. For each of these aims, the chapter considers and rejects arguments against employing cognitive scientific research in normative inquiry. It concludes by suggesting that, whichever of the central aims one begins from, normative ethics is improved by engaging with the science of moral (...) cognition. (shrink)
