Metaethics

In philosophy, meta-ethics—sometimes known as analytic ethics —is the branch of ethics that seeks to understand the nature of ethical properties, and ethical statements, attitudes, and judgments. Another way of saying it is that metaethics is reasoning about the presuppositions behind or underneath a normative ethical view or theory.

Meta-ethics is one of the three branches of ethics generally recognized by philosophers, the others being ethical theory and applied ethics. Ethical theory and applied ethics comprise normative ethics. In the 20th century, most work in ethics by academic philosophers was concerned with meta-ethics.

While normative ethics addresses such questions as "Which things are (morally) good and bad?" and "What should we do?", thus endorsing some ethical evaluations and rejecting others. Meta-ethics addresses such questions as: "What is (moral or ethical) goodness?" "What does it mean to say that something is good?" "What are the characteristics or qualities of an acceptable or defensible ethical theory?" "What is justice?" "How, if at all, can an ethical theory be justified?" "How do we know or recognize that something is or is not ethically good?" Meta-ethics seeks to understand the nature of ethical properties and evaluations.

Meta-ethical questions

In addition to those given above, examples of meta-ethical questions include:

• What does it mean to say something is "ethically good"?
• How, if at all, do we know what is right and wrong?
• How do moral attitudes motivate action?
• Are there objective or absolute values?
• What is the source of our values?
• Is it possible to justify out ethical judgements?
• Can there be a universal ethics, or can there be only culture-dependent or culture-specific ethical judgements or norms that are relative to a given culture?

Meta-ethical theories

A meta-ethical theory, unlike a normative ethical theory, does not contain any ethical evaluations. Instead, metaethical statements are statements about ethics as such, and not about problems of ethics as those problems are commonly experienced.

The major meta-ethical views are commonly divided into realist and anti-realist views, despite the fact that some labels, such as cognitivism, do not respect the realist/anti-realist boundary:

• Moral realism holds that there are objective values. Realists believe that evaluative statements are factual claims, which are either true or false, and that their truth or falsity does not depend on our beliefs, feelings, or other attitudes towards the things that are evaluated. Moral realism comes in two variants:
  • Ethical intuitionism and ethical non-naturalism, which hold that there are objective, irreducible moral properties (such as the property of 'goodness'), and that we sometimes have intuitive awareness of moral properties or of moral truths. Moral sense theory holds that humans have a moral sense, analogous to the physical senses, by which they perceive ethical principles or ethical facts. Important proponents of ethical intuitionism and moral sense theory were, in the the 18th century: the Third Earl of Shaftesbury, Francis Hutchenson, and David Hume. In 20th century: G.E. Moore's Principia Ethica, and W.D. Ross’s (1877-1971) theory of prima facie duties. At the end of the 20th century the view was revisited in James Q. Wilson's The Moral Sense (1993).
  • Ethical naturalism, which holds that there are objective moral properties but that these properties are reducible to entirely non-ethical properties. Most ethical naturalists hold that we have empirical knowledge of moral truths. Several have argued that moral knowledge can be gained by the same means as scientific knowledge. The ancient Greek philosopher Aristotle can be understood as having been an ethical naturalist because he argued that, just as there is a nature for each animal, there is a nature for humans, and ethics consists of developing human virtues in conformity with human nature.
• Moral anti-realism holds that there are no objective values. This view comes in three variants:
  • Ethical subjectivism, which holds that moral statements are made true or false by the attitudes and/or conventions of observers. There are several different versions of subjectivism, including:
    • Moral relativism (compare "cultural relativism"): This is the view that for a thing to be morally right is for it to be approved of by society; this leads to the conclusion that different things are right for people in different societies and different periods in history. Though long out of favor among academic philosophers, this view has been popular among anthropologists, such as Ruth Benedict.
    • The divine command theory: Another subjectivist theory holds that for a thing to be right is for a unique being, God, to approve of it, and that what is right for non-God beings is obedience to the divine will. This view was criticized by Plato in the Euthyphro but retains some modern defenders (Robert Adams, Philip Quinn, and others).
    • Individualist subjectivism: Another view is that there are as many distinct scales of good and evil as there are subjects in the world. This view was put forward by Protagoras.
    • The ideal observer theory: Finally, some hold that what is right is determined by the attitudes that a hypothetical ideal observer would have. An ideal observer is usually characterized as a being who is perfectly rational, imaginative, and informed, among other things. Richard Brandt is best-known for his defense of this view.
  • Non-cognitivism, which holds that ethical sentences are neither true nor false because they do not assert genuine propositions. Non-cognitivism encompasses:
    • Emotivism, defended by A.J. Ayer and C.L. Stevenson, which holds that ethical sentences serve merely to express emotions. So "Killing is wrong" means something like, "Boo on killing!"
    • Prescriptivism, defended by R.M. Hare, which holds that moral statements function like imperatives. So "Killing is wrong" means something like, "Don't kill!"
    • Quasi-realism, defended by Simon Blackburn, which holds that ethical statements behave linguistically like factual claims and can be appropriately called "true" or "false", even though there are no ethical facts for them to correspond to.
  • Error theory, which holds that ethical sentences are generally false. Error theorists hold that there are no objective values, but that the claim that there are objective values is part of the meaning of ordinary ethical sentences; that is why, in their view, ethical sentences are false. J. L. Mackie was the best-known proponent of this view. The error theory is also sometimes called "moral skepticism" or "nihilism."

Subjectivism, non-cognitivism, and error theory are the only forms of anti-realism: If there are no objective values, this must be either because ethical statements are subjective claims (as subjectivists maintain), because they are not genuine claims at all (as non-cognitivists maintain), or because they are mistaken objective claims. The only alternative is for ethical statements to be correct objective claims, which entails moral realism.

Another way of categorizing meta-ethical theories distinguishes between monistic theories (in which there is one true, or at least one highest, good) and pluralistic theories.

Value pluralism contends that there are two or more genuine values, knowable as such, yet incommensurable, so that any prioritization of these values is either non-cognitive or subjective. A value pluralist might, for example, contend that both the life of a nun and that of a mother realize genuine values (in an objective and cognitivist sense), yet there is no purely rational measure of which is preferable. See Isaiah Berlin.

History

Metaethical concerns and questions have been raised from antiquity. Plato asked how one would recognize the solution to a problem — and that would include a metaethical problem such as "What is Justice?" — unless one already knew the answer in some way. Plato also proposed answers to the questions, "Why should I be moral?" and "Can there be a universal ethics?" although he used different terminology; the Republic contains his answers to those questions. Aristotle too raised meta-ethical questions in his Nichomachean Ethics.

Some observe that in the 20th and 21st centuries meta-ethics has come to replace normative ethics as the more prevalent pursuit among academic philosophers. This is thought to have occurred, both in academia and in global society generally, at the same time as an overall decline of belief in moral absolutes, as well as a greater interest in process and categorization of norms than in identification and application. Others suggest that this trend is imagined, pointing to the ongoing growth of normative theory.
