, meta-ethics is the study of the nature, scope, and meaning of
moral judgment. It is one of the three branches of ethics generally studied by
philosophers, the others being
normative ethics (questions of how one ought to be and act) and
applied ethics
Applied ethics refers to the practical aspect of moral considerations. It is ethics with respect to real-world actions and their moral considerations in the areas of private and public life, the professions, health, technology, law, and leaders ...
(practical questions of right behavior in given, usually contentious, situations).
While normative ethics addresses such questions as "What should I do?", evaluating specific practices and principles of action, meta-ethics addresses questions such as "What ''is''
good
In most contexts, the concept of good denotes the conduct that should be preferred when posed with a choice between possible actions. Good is generally considered to be the opposite of evil and is of interest in the study of ethics, morality, p ...
ness?" and "How can we tell what is good from what is bad?", seeking to understand the assumptions underlying normative theories. Another distinction often made is that normative ethics involves first-order or substantive questions; meta-ethics involves second-order or formal questions.
Some theorists argue that a
metaphysical account of
morality
Morality () is the differentiation of intentions, decisions and actions between those that are distinguished as proper (right) and those that are improper (wrong). Morality can be a body of standards or principles derived from a code of cond ...
is necessary for the proper evaluation of actual moral theories and for making practical moral decisions; others reason from opposite premises and suggest that studying moral judgments about proper actions can guide us to a true account of the nature of morality.
Meta-ethical questions
According to Richard Garner and Bernard Rosen, there are three kinds of meta-ethical problems, or three general questions:
#What is the meaning of moral terms or judgments ? (moral

)
#*Asks such questions as how we can know if something is right or wrong, if at all.
Garner and Rosen say that answers to the three basic questions "are not unrelated, and sometimes an answer to one will strongly suggest, or perhaps even entail, an answer to another."
A meta-ethical theory, unlike a
normative ethical theory, does not attempt to evaluate specific choices as being better, worse, good, bad, or evil; although it may have profound implications as to the validity and meaning of normative ethical claims. An answer to any of the three example questions above would not itself be a normative ethical statement.
Moral semantics
Moral semantics attempts to answer the question, "What is the meaning of moral terms or judgments?" Answers may have implications for answers to the other two questions as well.
Cognitivist theories
''
Cognitivist'' theories hold that evaluative moral sentences express
proposition
In logic and linguistics, a proposition is the meaning of a declarative sentence. In philosophy, "meaning" is understood to be a non-linguistic entity which is shared by all sentences with the same meaning. Equivalently, a proposition is the no ...
s (i.e., they are 'truth-apt' or '
truth bearers', capable of being true or false), as opposed to
non-cognitivism. Most forms of cognitivism hold that some such propositions are true (including moral realism and ethical subjectivism), as opposed to
error theory, which asserts that all are erroneous.
Moral realism
Moral realism (in the ''robust'' sense;
cf. moral universalism
Moral universalism (also called moral objectivism) is the meta-ethical position that some system of ethics, or a universal ethic, applies universally, that is, for "all similarly situated individuals", regardless of culture, race, sex, reli ...
for the minimalist sense) holds that such propositions are about ''robust'' or mind-independent facts, that is, not facts about any person or group's subjective opinion, but about objective features of the world. Meta-ethical theories are commonly categorized as either a form of realism or as one of three forms of "
anti-realism" regarding moral facts:
ethical subjectivism,
error theory, or
non-cognitivism. Realism comes in two main varieties:
# ''
Ethical naturalism'' holds that there are objective moral properties and that these properties are
reducible or stand in some metaphysical relation (such as
supervenience) to entirely non-ethical properties. Most ethical naturalists hold that we have
empirical knowledge of moral truths. Ethical naturalism was implicitly assumed by many
modern ethical theorists, particularly
utilitarians.
# ''
Ethical non-naturalism'', as put forward by
G. E. Moore, holds that there are objective and ''irreducible'' moral properties (such as the property of 'goodness'), and that we sometimes have
intuitive

open question argument against what he considered the
naturalistic fallacy was largely responsible for the birth of meta-ethical research in contemporary
analytic philosophy

.
Ethical subjectivism
Ethical subjectivism is one form of moral anti-realism. It holds that moral statements are made true or false by the attitudes and/or conventions of people, either those of each society, those of each individual, or those of some particular individual. Most forms of ethical subjectivism are
relativist, but there are notable forms that are
universalist:
*
Ideal observer theory holds 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. Though a subjectivist theory due to its reference to a particular (albeit hypothetical) subject, Ideal Observer Theory still purports to provide
universal answers to moral questions.
*
Divine command 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
''Euthyphro'' (; grc, Εὐθύφρων, translit=Euthyphrōn; c. 399–395 BC), by Plato, is a Socratic dialogue whose events occur in the weeks before the trial of Socrates (399 BC), between Socrates and Euthyphro. The dialogue covers s ...
'' (see the
Euthyphro problem) but retains some modern defenders (
Robert Adams, Philip Quinn, and others). Like ideal observer theory, divine command theory purports to be
universalist despite its subjectivism.
Error theory
Error theory, another form of moral anti-realism, holds that although ethical claims do express propositions, all such propositions are false. Thus, both the statement "Murder is morally wrong" and the statement "Murder is morally permissible" are false, according to error theory.
J. L. Mackie is probably the best-known proponent of this view. Since error theory denies that there are moral truths, error theory entails
moral nihilism and, thus,
moral skepticism; however, neither moral nihilism nor moral skepticism conversely entail error theory.
Non-cognitivist theories
Non-cognitivist theories hold that ethical sentences are neither true nor false because they do not express genuine
proposition
In logic and linguistics, a proposition is the meaning of a declarative sentence. In philosophy, "meaning" is understood to be a non-linguistic entity which is shared by all sentences with the same meaning. Equivalently, a proposition is the no ...
s. Non-cognitivism is another form of moral anti-realism. Most forms of non-cognitivism are also forms of
expressivism, however some such as Mark Timmons and Terrence Horgan distinguish the two and allow the possibility of cognitivist forms of expressivism. Non-cognitivism includes:
*
Emotivism, defended by
A. J. Ayer and
Charles Stevenson, holds that ethical sentences serve merely to express emotions. Ayer argues that ethical sentences are expressions of approval or disapproval, not assertions. So "Killing is wrong" means something like "Boo on killing!".
*
Quasi-realism, defended by
Simon Blackburn, 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.
Projectivism
Projectivism in philosophy involves attributing (projecting) qualities to an object as if those qualities actually belong to it. It is a theory for how people interact with the world and has been applied in both ethics and general philosophy. I ...
and
moral fictionalism are related theories.
*
Universal prescriptivism, defended by
R. M. Hare, holds that moral statements function like universalized
imperative sentences. So "Killing is wrong" means something like "Don't kill!" Hare's version of prescriptivism requires that moral prescriptions be
universalizable, and hence actually have objective values, in spite of failing to be
indicative statements with
truth-values per se.
Centralism and non-centralism
Yet another way of categorizing meta-ethical theories is to distinguish between centralist and non-centralist moral theories. The debate between centralism and non-centralism revolves around the relationship between the so-called "thin" and "thick" concepts of morality: thin moral concepts are those such as good, bad, right, and wrong; thick moral concepts are those such as courageous, inequitable, just, or dishonest. While both sides agree that the thin concepts are more general and the thick more specific, centralists hold that the thin concepts are antecedent to the thick ones and that the latter are therefore dependent on the former. That is, centralists argue that one must understand words like "right" and "ought" before understanding words like "just" and "unkind." Non-centralism rejects this view, holding that thin and thick concepts are on par with one another and even that the thick concepts are a sufficient starting point for understanding the thin ones.
Non-centralism has been of particular importance to ethical naturalists in the late 20th and early 21st centuries as part of their argument that normativity is a non-excisable aspect of language and that there is no way of analyzing thick moral concepts into a purely descriptive element attached to a thin moral evaluation, thus undermining any fundamental division between facts and norms.
Allan Gibbard,
R. M. Hare, and
Simon Blackburn have argued in favor of the fact/norm distinction, meanwhile, with Gibbard going so far as to argue that, even if conventional English has only mixed normative terms (that is, terms that are neither purely descriptive nor purely normative), we could develop a nominally English metalanguage that still allowed us to maintain the division between factual descriptions and normative evaluations.
Moral ontology
Moral ontology attempts to answer the question, "What is the nature of moral judgments?"
Amongst those who believe there to be some standard(s) of morality (as opposed to
moral nihilists), there are two divisions:
#
universalists, who hold that the same moral facts or principles apply to everyone everywhere; and
#
relativists, who hold that different moral facts or principles apply to different people or societies.

Universalist theories are generally forms of
moral realism, though exceptions exists, such as the subjectivist
ideal observer and
divine command theories, and the non-cognitivist
universal prescriptivism of
R. M. Hare. Forms of moral universalism include:
* Value monism is the common form of universalism, which holds that all goods are
commensurable
Two concepts or things are commensurable if they are measurable or comparable by a common standard.
Commensurability most commonly refers to commensurability (mathematics). It may also refer to:

*
Value pluralism
In ethics, value pluralism (also known as ethical pluralism or moral pluralism) is the idea that there are several values which may be equally correct and fundamental, and yet in conflict with each other. In addition, value-pluralism postulates t ...
contends that there are two or more genuine scales of value, 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 a life as a nun and a life as a mother realize genuine values (in a universalist sense), yet they are incompatible (nuns may not have children), and there is no purely rational way to measure which is preferable. A notable proponent of this view is
Isaiah Berlin.
Moral relativism
Moral relativism
Moral relativism or ethical relativism (often reformulated as relativist ethics or relativist morality) is used to describe several philosophical positions concerned with the differences in moral judgments across different peoples and cultures. ...
maintains that all moral judgments have their origins either in societal or in individual standards, and that no single standard exists by which one can objectively assess the truth of a moral proposition. Meta-ethical relativists, in general, believe that the descriptive properties of terms such as "good", "bad", "right", and "wrong" do not stand subject to
universal truth conditions, but only to societal convention and personal preference. Given the same set of verifiable facts, some societies or individuals will have a fundamental disagreement about what one ''ought'' to do based on societal or individual
norms, and one cannot adjudicate these using some independent standard of evaluation. The latter standard will always be societal or personal and not universal, unlike, for example, the scientific standards for assessing

or for determining
mathematical truths.
Moral nihilism
Moral nihilism, also known as ethical nihilism, is the meta-ethical view that nothing has intrinsic moral value. For example, a moral nihilist would say that killing someone, for whatever reason, is intrinsically neither morally right nor morally wrong. Moral nihilism must be distinguished from
moral relativism
Moral relativism or ethical relativism (often reformulated as relativist ethics or relativist morality) is used to describe several philosophical positions concerned with the differences in moral judgments across different peoples and cultures. ...
, which does allow for moral statements to be intrinsically true or false in a non-universal sense, but does not assign any static truth-values to moral statements. Insofar as only true statements can be known, moral nihilists are
moral skeptics. Most forms of moral nihilism are
non-cognitivist and vice versa, though there are notable exceptions such as
universal prescriptivism (which is semantically non-cognitive but substantially universal).
Moral epistemology
Moral epistemology is the study of moral knowledge. It attempts to answer such questions as, "How may moral judgments be supported or defended?" and "Is moral knowledge possible?"
If one presupposes a cognitivist interpretation of moral sentences, morality is justified by the moralist's knowledge of moral facts, and the theories to justify moral judgements are epistemological theories. Most moral epistemologies posit that moral knowledge is somehow possible (including empiricism and moral rationalism), as opposed to
moral skepticism. Amongst them, there are those who hold that moral knowledge is gained inferentially on the basis of some sort of non-moral epistemic process, as opposed to
ethical intuitionism.
Moral knowledge gained by inference
Empiricism
Empiricism is the doctrine that knowledge is gained primarily through observation and experience. Meta-ethical theories that imply an empirical epistemology include:
*
ethical naturalism, which holds moral facts to be reducible to non-moral facts and thus knowable in the same ways; and
* most common forms of
ethical subjectivism, which hold that moral facts reduce to facts about individual opinions or cultural conventions and thus are knowable by observation of those conventions.
There are exceptions within subjectivism however, such as
ideal observer theory, which implies that moral facts may be known through a rational process, and
individualist ethical subjectivism
Ethical subjectivism or moral non-objectivism is the meta-ethical view which claims that:
#Ethical sentences express propositions.
#Some such propositions are true.
#The truth or falsity of such propositions is ineliminably dependent on the (act ...
, which holds that moral facts are merely personal opinions and so may be known only through introspection. Empirical arguments for ethics run into the ''
is-ought'' problem, which asserts that the way the world ''is'' cannot alone instruct people how they ''ought'' to act.
Moral rationalism
Moral rationalism, also called ethical rationalism, is the view according to which moral truths (or at least general moral principles) are knowable ''
a priori'', by reason alone. Some prominent figures in the
history of philosophy
Philosophy (from , ) is the systematized study of general and fundamental questions, such as those about existence, reason, knowledge, values, mind, and language. Such questions are often posed as problems to be studied or resolved. Some ...

.
Recent philosophers who defended moral rationalism include
R. M. Hare,
Christine Korsgaard,
Alan Gewirth, and
Michael Smith. A moral rationalist may adhere to any number of different semantic theories as well;
moral realism is compatible with rationalism, and the subjectivist
ideal observer theory and non-cognitivist
universal prescriptivism both entail it.
Ethical intuitionism
Ethical intuitionism is the view according to which some moral truths can be known ''without'' inference. That is, the view is at its core a
foundationalism about moral beliefs. Such an epistemological view implies that there are moral beliefs with propositional contents; so it implies
cognitivism. Ethical intuitionism commonly suggests
moral realism, the view that there are
objective facts of morality and, to be more specific,
ethical non-naturalism, the view that these evaluative facts cannot be reduced to natural fact. However, neither moral realism nor ethical non-naturalism are essential to the view; most ethical intuitionists simply happen to hold those views as well. Ethical intuitionism comes in both a "rationalist" variety, and a more "empiricist" variety known as
moral sense theory.
Moral skepticism
Moral skepticism is the
class of meta-ethical theories all members of which entail that no one has any moral knowledge. Many moral skeptics also make the stronger,
modal, claim that moral knowledge is impossible. Forms of moral skepticism include, but are not limited to,
error theory and most but not all forms of
non-cognitivism.
