High Quality Content by WIKIPEDIA articles! Moral reasoning is a study in psychology that overlaps with moral philosophy. It is also called moral development. Prominent contributors to theory include Lawrence Kohlberg and Elliot Turiel. The term is sometimes used in a different sense: reasoning under conditions of uncertainty, such as obtain in a court of law. It is this sense that gave rise to the phrase, "To a moral certainty;" however, this sense is now seldom used outside of charges to juries.
