Morality (from the Latin moralitas "manner, character, proper behavior") is a system of conduct and ethics that is virtuous. It can also be used in regard to sexual matters and chastity. Morality has three principal meanings:
In its "normative" sense, morality refers directly to what is right and wrong, regardless of what people think. It could be defined as the conduct of the ideal "moral" person in a certain situation. This usage of the term is characterized by "definitive" statements such as "That act is immoral" rather than descriptive ones such as "Many believe that act is immoral." It is often challenged by a moral skepticism, in which the unchanging existence of a rigid, universal, objective moral "truth" is rejected. The normative usage of the term "morality" is also addressed by normative ethics.
A key issue is the meaning of the terms "moral" or "immoral". Moral realism would hold that there are true moral statements which report objective moral facts, whereas moral anti-realism would hold that morality is derived from any one of the norms prevalent in society (cultural relativism); the edicts of a god (divine command theory); is merely an expression of the speakers' sentiments (emotivism); an implied imperative (universal prescriptivism); or falsely presupposes that there are objective moral facts (error theory). Some thinkers hold that there is no correct definition of right behavior, that morality can only be judged with respect to particular situations, within the standards of particular belief systems and socio-historical contexts. This position, known as moral relativism, often cites empirical evidence from anthropology as evidence to support its claims. The opposite view, that there are universal, eternal moral truths are known as moral absolutism. Moral absolutists might concede that forces of social conformity significantly shape moral decisions, but deny that cultural norms and customs define morally right behavior.
some observers hold that individuals apply distinct sets of moral rules to people depending on their membership of an "ingroup" (the individual and those they believe to be of the same culture or race) or an "outgroup" (people not entitled to be treated according to the same rules). Some biologists, anthropologists and evolutionary psychologists believe this ingroup-outgroup discrimination has evolved because it enhances group survival. Gary R. Johnson and V.S. Falger have argued that nationalism and patriotism are forms of this ingroup/outgroup boundary. Jonathan Haidt has noted that experimental observation indicates an ingroup criterion provides one moral foundation substantially used by conservatives, but far less so by liberals.
Fons Trompenaars, author of Did the Pedestrian Die?, tested members of different cultures with various moral dilemmas. One of these was whether the driver of a car would have his friend, a passenger riding in the car, lie in order to protect the driver from the consequences of driving too fast and hitting a pedestrian. Trompenaars found that different cultures had quite different expectations (from none to almost certain).
