Lawrence Kohlberg laid the groundwork for the current debate within psychology on moral development. He proposed that children form ways of thinking through their experiences which include understandings of moral concepts such as justice, rights, equality and human welfare. Kohlberg followed the development of moral judgment beyond the ages. He determined that the process of attaining moral maturity took longer and was more gradual than other studies have shown.

Within this level, a Stage 1 they focused on avoiding breaking rules that are backed by punishment, obedience for its own sake and avoiding the physical consequences of an action to persons and property.

The Golden Rule becomes, "If someone hits you, you hit them back." At Stage 2 one follows the rules only when it is to someone's immediate interests.

Within this level, individuals at Stage 3 are aware of shared feelings, agreements, and expectations which take primacy over individual interests. Persons at Stage 3 define what is right in terms of what is expected by people close to one's self, and in terms of the stereotypic roles that define being good. Being...
