What are 6 stage of moral development and the post conventional level of moral development?

The six stages of moral development, as proposed by Lawrence Kohlberg, are: 1) Obedience and punishment orientation, 2) Individualism and exchange, 3) Interpersonal relationships, 4) Maintaining social order, 5) Social contract and individual rights, and 6) Universal principles. The post-conventional level of moral development involves stages 5 and 6, where individuals develop their own ethical principles based on justice, human rights, and ethical principles that may transcend societal norms.
