Moral responsibility


Moral responsibility is an assignment of a duty or obligation to behave in a 'good' manner and refrain from behaving in a 'bad' manner. From a philosophical standpoint, the rationale behind 'good' and 'bad' is a subject for ethics[1] and metaethics.[2] Stent provides four conditions for assigning moral responsibility, among them the "duties and obligations devolving from moral, legal, or ritual imperatives".[3] In everyday life, obligation in this context is distinguished in part from milder demands for conformity like etiquette by the intense and insistent social pressure brought to bear upon those who deviate or threaten to deviate.[4] From an anthropological or sociological standpoint, the specifics of what is 'good' or 'bad', and the ways of enforcing acceptable behavior, vary considerably from one group to another.[5]

"Social learning theorists...feel that the learning of moral rules is not culturally invariant, but is, rather, critically related to particular learning environments and to the distinctive normative code of the society in question. The major influences on moral development are what B.F. Skinner calls "contingencies of reinforcement"...culturally variable factors that explain why different peoples acquire different types of moral orientations."

'Moral responsibility' is part of the interplay between the individual and their society, and study of this relationship is both a scientific and a philosophical investigation.[6][7]

"The study of ethics is concerned not only with identification of societal values but with thinking logically about ethical challenges and developing practical approaches to moral problem solving. Other disciplines also are concerned with discovering society's moral precepts. For example, sociology and anthropology each study cultural norms."[8]

A large part of the philosophical discussion of 'moral responsibility' is focused upon the logical implications (as distinct from the ascertainable facts, such as they may be) of whether or not humans actually are able to control their actions to some or another extent.[9][10] Resolution of that issue is the philosophical subject of free will, a continuing debate that began millennia ago and seems destined to continue indefinitely. It is known that humans' control over their actions is limited in some circumstances, and there is debate over the role of moral responsibility where there is only curtailed agency.
