Read the following description and identify the stage of moral reasoning of Kohlberg. Description: Right action is defined by self-chosen ethical principles of conscience that are valid for all humanity, regardless of law and social agreement.

Kohlberg's theory of moral development has three levels (preconventional, conventional, postconventional), each with two stages. The description refers to self-chosen ethical principles of conscience that apply universally to all humanity, regardless of laws or social agreements. This is the defining feature of Stage 6, the universal ethical principle orientation, which represents the highest stage of postconventional morality. At this stage, individuals follow internalized principles of justice, equality, and human dignity even when they conflict with laws.
