1. Metaethics
The term “meta” means after or beyond, and, consequently, the notion of metaethics involves a removed, or bird’s eye view of the entire project of ethics. We may define metaethics as the study of the origin and meaning of ethical concepts. When compared to normative ethics and applied ethics, the field of metaethics is the least precisely defined area of moral philosophy. It covers issues from moral semantics to moral epistemology[->0]. Two issues, though, are prominent: (1) metaphysical issues concerning whether morality exists independently of humans, and (2) psychological issues concerning the underlying mental basis of our moral judgments and conduct. a. Metaphysical Issues: Objectivism and Relativism

Metaphysics is the study of the kinds of things that exist in the universe. Some things in the universe are made of physical stuff, such as rocks; and perhaps other things are nonphysical in nature, such as thoughts, spirits, and gods. The metaphysical component of metaethics involves discovering specifically whether moral values are eternal truths that exist in a spirit-like realm, or simply human conventions. There are two general directions that discussions of this topic take, one other-worldly and one this-worldly. Proponents of the other-worldly view typically hold that moral values are objective[->1] in the sense that they exist in a spirit-like realm beyond subjective human conventions. They also hold that they are absolute, or eternal, in that they never change, and also that they are universal insofar as they apply to all rational creatures around the world and throughout time[->2]. The most dramatic example of this view is Plato[->3], who was inspired by the field of mathematics. When we look at numbers and mathematical relations, such as 1+1=2, they seem to be timeless concepts that never change, and apply everywhere in the universe. Humans do not invent numbers, and humans cannot alter them. Plato explained the eternal character of mathematics by stating that they are abstract entities that exist in a spirit-like realm. He noted that moral values also are absolute truths and thus are also abstract, spirit-like entities. In this sense, for Plato, moral values are spiritual objects. Medieval philosophers commonly grouped all moral principles together under the heading of “eternal law” which were also frequently seen as spirit-like objects. 17th century British philosopher Samuel Clarke described them as spirit-like relationships rather than spirit-like objects. In either case, though, they exist in a sprit-like realm. A different other-worldly approach to the metaphysical status of morality is divine commands issuing from God’s will. Sometimes called voluntarism (or divine command theory[->4]), this view was inspired by the notion of an all-powerful God[->5] who is in control of everything. God simply wills things, and they become reality. He wills the physical world into existence, he wills human life into existence and, similarly, he wills all moral values into existence. Proponents of this view, such as medieval philosopher William of Ockham[->6], believe that God wills moral principles, such as “murder is wrong,” and these exist in God’s mind as commands. God informs humans of these commands by implanting us with moral intuitions or revealing these commands in scripture. The second and more this-worldly approach to the metaphysical status of morality follows in the skeptical philosophical tradition, such as that articulated by Greek philosopher Sextus Empiricus, and denies the objective status of moral values. Technically, skeptics did not reject moral values themselves, but only denied that values exist as spirit-like objects, or as divine commands in the mind of God. Moral values, they argued, are strictly human inventions, a position that has since been called moral relativism[->7]. There are two distinct forms of moral relativism. The first is individual relativism, which holds that...
