In metaphilosophy and ethics, metaethics 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 and applied ethics.
Action theory is an area in philosophy concerned with theories about the processes causing willful human bodily movements of a more or less complex kind. This area of thought involves epistemology, ethics, metaphysics, jurisprudence, and philosophy of mind, and has attracted the strong interest of philosophers ever since Aristotle's Nicomachean Ethics. With the advent of psychology and later neuroscience, many theories of action are now subject to empirical testing.
Moral realism is the position that ethical sentences express propositions that refer to objective features of the world, some of which may be true to the extent that they report those features accurately. This makes moral realism a non-nihilist form of ethical cognitivism with an ontological orientation, standing in opposition to all forms of moral anti-realism and moral skepticism, including ethical subjectivism, error theory ; and non-cognitivism. Within moral realism, the two main subdivisions are ethical naturalism and ethical non-naturalism.
Christine Marion Korsgaard, is an American philosopher who is the Arthur Kingsley Porter Professor of Philosophy Emerita at Harvard University. Her main scholarly interests are in moral philosophy and its history; the relation of issues in moral philosophy to issues in metaphysics, the philosophy of mind, and the theory of personal identity; the theory of personal relationships; and in normativity in general.
The is–ought problem, as articulated by the Scottish philosopher and historian David Hume, arises when one makes claims about what ought to be that are based solely on statements about what is. Hume found that there seems to be a significant difference between descriptive or positive statements and prescriptive or normative statements, and that it is not obvious how one can coherently transition from descriptive statements to prescriptive ones. Hume's law or Hume's guillotine is the thesis that an ethical or judgmental conclusion cannot be inferred from purely descriptive factual statements.
Normative generally means relating to an evaluative standard. Normativity is the phenomenon in human societies of designating some actions or outcomes as good, desirable, or permissible, and others as bad, undesirable, or impermissible. A norm in this sense means a standard for evaluating or making judgments about behavior or outcomes. "Normative" is sometimes also used, somewhat confusingly, to mean relating to a descriptive standard: doing what is normally done or what most others are expected to do in practice. In this sense a norm is not evaluative, a basis for judging behavior or outcomes; it is simply a fact or observation about behavior or outcomes, without judgment. Many researchers in science, law, and philosophy try to restrict the use of the term "normative" to the evaluative sense and refer to the description of behavior and outcomes as positive, descriptive, predictive, or empirical.
Moral nihilism is the meta-ethical view that nothing is morally right or morally wrong and that morality doesn't exist.

Evolutionary ethics is a field of inquiry that explores how evolutionary theory might bear on our understanding of ethics or morality. The range of issues investigated by evolutionary ethics is quite broad. Supporters of evolutionary ethics have claimed that it has important implications in the fields of descriptive ethics, normative ethics, and metaethics.
Cornell realism is a view in meta-ethics, associated with the work of Richard Boyd, Nicholas Sturgeon, and David Brink. There is no recognized and official statement of Cornell realism, but several theses are associated with the view.
Metaepistemology is the branch of epistemology and metaphilosophy that studies the underlying assumptions made in debates in epistemology, including those concerning the existence and authority of epistemic facts and reasons, the nature and aim of epistemology, and the methodology of epistemology.

Pragmatic ethics is a theory of normative philosophical ethics and meta-ethics. Ethical pragmatists such as John Dewey believe that some societies have progressed morally in much the way they have attained progress in science. Scientists can pursue inquiry into the truth of a hypothesis and accept the hypothesis, in the sense that they act as though the hypothesis were true; nonetheless, they think that future generations can advance science, and thus future generations can refine or replace their accepted hypotheses. Similarly, ethical pragmatists think that norms, principles, and moral criteria are likely to be improved as a result of inquiry.

Much of her work has taken a practical, empirical approach to philosophical questions, trying to show how these disciplines can improve the world for the better.
Constitutivism is the position in meta-ethics which links what we ought to do morally with the rules about our make up as agents who perform actions of any kind. It claims to answer doubts about the validity of moral judgements, and about moral objectivity, by explaining that we cannot help but act, therefore we act in accordance with moral rules which are essential to any acting being.

Humeanism refers to the philosophy of David Hume and to the tradition of thought inspired by him. Hume was an influential Scottish philosopher well known for his empirical approach, which he applied to various fields in philosophy. In the philosophy of science, he is notable for developing the regularity theory of causation, which in its strongest form states that causation is nothing but constant conjunction of certain types of events without any underlying forces responsible for this regularity of conjunction. This is closely connected to his metaphysical thesis that there are no necessary connections between distinct entities. The Humean theory of action defines actions as bodily behavior caused by mental states and processes without the need to refer to an agent responsible for this. The slogan of Hume's theory of practical reason is that "reason is...the slave of the passions". It restricts the sphere of practical reason to instrumental rationality concerning which means to employ to achieve a given end. But it denies reason a direct role regarding which ends to follow. Central to Hume's position in metaethics is the is-ought distinction. It states that is-statements, which concern facts about the natural world, do not imply ought-statements, which are moral or evaluative claims about what should be done or what has value. In philosophy of mind, Hume is well known for his development of the bundle theory of the self. It states that the self is to be understood as a bundle of mental states and not as a substance acting as the bearer of these states, as is the traditional conception. Many of these positions were initially motivated by Hume's empirical outlook. It emphasizes the need to ground one's theories in experience and faults opposing theories for failing to do so. But many philosophers within the Humean tradition have gone beyond these methodological restrictions and have drawn various metaphysical conclusions from Hume's ideas.
