The Philosophy Of Moral Development by Lawrence Kohlberg

Moral Stages and the Idea of Justice

Presents a cognitive-developmental account of how moral reasoning advances through invariant stages—from obedience and self-interest to social conformity and ultimately principled justice—supported by cross-cultural research and moral-dilemma interviews. It argues that justice is the central organizing concept of morality, defends the universality of higher-stage reasoning against relativism, and critiques behaviorist and utilitarian approaches. The work links empirical findings to philosophical traditions, details methods for assessing moral judgment, and proposes educational practices, such as just community schools, to foster growth toward postconventional moral understanding.
