Abstract

Suppose there are two people having a moral disagreement about, say, abortion. They argue in a familiar way about whether fetuses have rights, whether a woman’s right to autonomy over her body overrides the fetus’s welfare, and so on. But then suppose one of the people says “Oh, it’s all just a matter of opinion; there’s no objective fact about whether fetuses have rights. When we say that something is morally forbidden, all we’re really doing is expressing our disapproval of it.” The other person protests: “No!—that’s totally wrong. Of course there are objective moral truths.” And suppose their dispute now settles on this new matter of whether there are objective moral facts, and the debate continues. They’ve now stopped discussing abortion, and are discussing the nature of any moral debate about abortion; they’ve stopped doing ethics, and started doing metaethics. If wondering about what one morally ought to do is to engage in ethical thought, then wondering about what one is doing when one wonders about what one morally ought to do is to engage in metaethical thought. When we make public moral judgments are we stating facts, or are we just expressing our opinions? And if there are moral facts, then what kind of fact are they? Can moral judgments be true or false? Can moral judgments be justified, and if so how? These kinds of questions are the domain of metaethics. (I’m not saying that there is a crisp and principled line to be drawn between meta-ethics and regular ethical discourse; but it is, if nothing else, a pedagogically useful division of labor.).
