Irrealism in Ethics

Irrealism in Ethics presents a collection of six original essays contributed by prominent moral philosophers that address various forms of the philosophical position of ethical irrealism. Readings offer innovative approaches to the arguments both for and against the two major versions of ethical irrealism—the error theory and expressivism. Topics discussed include whether the facts about the evolutionary origins of morality support a moral error theory, whether or not a moral error theory makes sense of the fact that it is possible to give and receive good moral advice, and why one would continue making moral judgments if one believed in a moral error theory. Other provocative questions address whether or not the possibility of faultless moral disagreement establishes that a form of ethical irrealism is true, and whether the error theory or expressivism is the more plausible form of irrealism. Strikingly original, Irrealism in Ethics offers thought–provoking insights into the nature of ethics and meaning of moral language.
