A Defense of Ethical Relativism

Among naturalist philosophers, both defenders and opponents of moral relativism argue that prescriptive moral theories (or normative theories) should be constrained by empirical findings about human psychology. Empiricists have asked if people are or can be moral relativists, and what effect being a moral relativist can have on an individual’s moral functioning. This research is underutilized in philosophers’ normative theories of relativism; at the same time, the empirical work, while useful, is conceptually disjointed. Our goal is to integrate philosophical and empirical work on constraints on normative relativism. First, we present a working definition of moral relativism. Second, we outline naturalist versions of normative relativism, and third, we highlight the empirical constraints in this reasoning. Fourth, we discuss recent studies in moral psychology that are relevant for the philosophy of moral relativism. We assess here what conclusions for moral relativism can and cannot be drawn from experimental studies. Finally, we suggest how moral philosophers and moral psychologists can collaborate on the topic of moral relativism in the future.

Synthese, 2009

I argue that evolutionary strategies of kin selection and game-theoretic reciprocity are apt to generate agent-centered and agent- neutral moral intuitions, respectively. Such intuitions are the building blocks of moral theories, resulting in a fundamental schism between agent-centered theories on the one hand and agent-neutral theories on the other. An agent-neutral moral theory is one according to which everyone has the same duties and moral aims, no matter what their personal interests or interpersonal relationships. Agent-centered moral theories deny this and include at least some prescriptions that include ineliminable indexicals. I argue that there are no rational means of bridging the gap between the two types of theories; nevertheless this does not necessitate skepticism about the moral—we might instead opt for an ethical relativism in which the truth of moral statements is relativized to the perspective of moral theories on either side of the schism. Such a relativism does not mean that any ethical theory is as good as any other; some cannot be held in reflective equilibrium, and even among those that can, there may well be pragmatic reasons that motivate the selection of one theory over another. But if no sort of relativism is deemed acceptable, then it is hard to avoid moral skepticism.

Common sense and the pursuit of science both assume that there is a stable external reality including things, animals, and other people whose properties cannot be altered merely by our wishing that they were different, or by how we define them, and that we come to understand these properties by experience and reasoning. While absolute certainty can never be attained, at least some closer approximation to the truth can be reached by the successive elimination of errors.
