Introduction

Are there objective moral truths? In answering this question, more and more researchers have recently begun to appeal to evidence from empirical sciences. In this chapter, I introduce this scientific approach to the moral realism/anti-realism debate. First, I explain this debate. Then I sketch how and in which sense the scientific approach to it has recently become popular. Finally, I specify my book’s main theses, identify ways in which it advances our understanding of realist and anti-realist appeals to science and outline its content.
