ABSTRACT
This chapter surveys some of the main arguments from moral disagreement to moral relativism. I begin by discussing how disagreement differs from the related phenomenon of moral diversity. I then discuss four main lines of argument from disagreement to relativism: inference to the best explanation, epistemic arguments, semantic arguments, and arguments from incommensurability. The chapter concludes by discussing various types of empirical evidence for these arguments, ranging from ethnographic studies to experimental studies of moral psychology.
