Evolutionary Debunking

AbstractSidgwick's seminal text The Methods of Ethics left off with an unresolved problem that Sidgwick referred to as the dualism of practical reason. The problem is that employing Sidgwick's methodology of rational intuitionism appears to show that there are reasons to favour both egoism and utilitarianism. Katarzyna de Lazari-Radek and Peter Singer offer a solution in the form of an evolutionary debunking argument: the appeal of egoism is explainable in terms of evolutionary theory. I argue that like rational prudence, rational benevolence is subject to debunking arguments and so problematic, but also – and more importantly – that debunking arguments are irrelevant in the debate over the dualism of practical reason on the view of reason and rational intuitionism that Lazari-Radek and Singer embrace. Either both egoism and utilitarianism are debunked, or neither are. If I am right, Sidgwick's dualism is left standing.

Principal Parts

Nietzsche is one of the most subversive ethical thinkers of the Western canon. This book offers a critical assessment of his ethical thought and its significance for contemporary moral philosophy. It develops a charitable but critical reading of his thought, pushing some claims and arguments as far as seems fruitful while rejecting others. But it also uses Nietzsche in dialogue with, so to contribute to, a range of long-standing issues within normative ethics, metaethics, value theory, practical reason, and moral psychology. The book is divided into three principal parts. Part I examines Nietzsche’s critique of morality, arguing that it raises well-motivated challenges to morality’s normative authority and value: his error theory about morality’s categoricity is in a better position than many contemporary versions; and his critique of moral values has bite even against undemanding moral theories, with significant implications not just for rarefied excellent types but also us. Part II turns to moral psychology, attributing to Nietzsche and defending a sentimentalist explanation of action and motivation. Part III considers his non-moral perfectionism, developing models of value and practical normativity that avoid difficulties facing many contemporary accounts and that may therefore be of wider interest. The discussion concludes by considering Nietzsche’s broader significance: as well as calling into question many of moral philosophy’s deepest assumptions, he challenges our usual views of what ethics itself is—and what it, and we, should be doing.

This chapter argues that evolutionary debunking arguments are dialectically ineffective. Such arguments rely on the premise that moral judgements can be given evolutionary explanations which do not invoke their truth. The challenge for the debunker is to bridge the gap between this premise and the conclusion that moral judgements are unjustified. After discussing older attempts to bridge this gap, this chapter focuses on Joyce’s recent attempt, which claims that ‘we do not have a believable account of how moral facts could explain the mechanisms…which give rise to moral judgements’. It argues that whether there is such an account depends on what it is permissible to assume about moral truth and that it is reasonable to make assumptions which allow for the possibility of at least partial moral epistemologies. The challenge for the debunker is to show that these assumptions are unreasonable in a way which does not render their debunking argument superfluous.

Ethical Project

This opening chapter explains the book’s overarching aims, themes, structure, and approach. The book’s aim is to critically assess Nietzsche’s ethical thought and its significance for contemporary (broadly analytic) moral philosophy. It does this in two main ways: by developing a charitable but critical reconstruction of his ethics; and by using Nietzsche to contribute to a range of longstanding issues within normative ethics, metaethics, value theory, practical reason, and moral psychology. The chapter locates Nietzsche’s ethical project in his ‘revaluation of all values’, outlining a variety of interpretive and philosophical puzzles this raises. It then gives a chapter-by-chapter overview of the book’s topics and direction, and addresses some methodological matters bearing on its interpretive and philosophical ambitions.

Commonsense Morality

Abstract Regard for Reason in the Moral Mind argues that a careful examination of the scientific literature reveals a foundational role for reasoning in moral thought and action. Grounding moral psychology in reason then paves the way for a defense of moral knowledge and virtue against a variety of empirical challenges, such as debunking arguments and situationist critiques. The book attempts to provide a corrective to current trends in moral psychology, which celebrate emotion over reason and generate pessimism about the psychological mechanisms underlying commonsense morality. Ultimately, there is rationality in ethics not just despite but in virtue of the neurobiological and evolutionary materials that shape moral cognition and motivation.
