MoralityMorality () 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 conduct from a particular philosophy, religion or culture, or it can derive from a standard that a person believes should be universal. Morality may also be specifically synonymous with "goodness" or "rightness".
Moral realismMoral realism (also ethical realism) is the position that ethical sentences express propositions that refer to objective features of the world (that is, features independent of subjective opinion), some of which may be true to the extent that they report those features accurately.
DeontologyIn moral philosophy, deontological ethics or deontology (from Greek: δέον + λόγος) is the normative ethical theory that the morality of an action should be based on whether that action itself is right or wrong under a series of rules and principles, rather than based on the consequences of the action. It is sometimes described as duty-, obligation-, or rule-based ethics. Deontological ethics is commonly contrasted to consequentialism, utilitarianism, virtue ethics, and pragmatic ethics.
Moral nihilismMoral nihilism (also known as ethical nihilism) is the meta-ethical view that nothing is objectively morally right or objectively morally wrong. Moral nihilism is distinct from moral relativism, which allows for actions to be wrong relative to a particular culture or individual. It is also distinct from expressivism, according to which when we make moral claims, "We are not making an effort to describe the way the world is ... we are venting our emotions, commanding others to act in certain ways, or revealing a plan of action".
MetaethicsIn 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 (questions of how one ought to be and act) and applied ethics (practical questions of right behavior in given, usually contentious, situations).
Natural rights and legal rightsSome philosophers distinguish two types of rights, natural rights and legal rights. Natural rights are those that are not dependent on the laws or customs of any particular culture or government, and so are universal, fundamental and inalienable (they cannot be repealed by human laws, though one can forfeit their enjoyment through one's actions, such as by violating someone else's rights). Natural law is the law of natural rights. Legal rights are those bestowed onto a person by a given legal system (they can be modified, repealed, and restrained by human laws).
UtilitarianismIn ethical philosophy, utilitarianism is a family of normative ethical theories that prescribe actions that maximize happiness and well-being for all affected individuals. Although different varieties of utilitarianism admit different characterizations, the basic idea behind all of them is, in some sense, to maximize utility, which is often defined in terms of well-being or related concepts. For instance, Jeremy Bentham, the founder of utilitarianism, described utility as: That property in any object, whereby it tends to produce benefit, advantage, pleasure, good, or happiness .
Ethical intuitionismEthical intuitionism (also called moral intuitionism) is a view or family of views in moral epistemology (and, on some definitions, metaphysics). It is foundationalism applied to moral knowledge, the thesis that some moral truths can be known non-inferentially (i.e., known without one needing to infer them from other truths one believes). Such an epistemological view is by definition committed to the existence of knowledge of moral truths; therefore, ethical intuitionism implies cognitivism.
