Kohlberg's theory of moral development has three levels - pre-conventional, conventional, and post-conventional. The pre-conventional level is focused on obedience and self-interest. The conventional level focuses on living up to group expectations and maintaining social order. The post-conventional level involves defining moral values based on principles of justice and respect for human dignity rather than rules or authority. It has six stages total, with the final stage being governance by self-chosen ethical principles of equality and respect for all people.
