The study of moral development occupies a central position in contemporary psychology, philosophy, and educational theory. Among the scholars who profoundly shaped this interdisciplinary field, Lawrence Kohlberg stands as one of the most influential and debated figures of the twentieth century. Building upon the cognitive-developmental foundations established by Jean Piaget, Kohlberg proposed that moral reasoning evolves through a sequence of qualitatively distinct stages, reflecting increasingly complex understandings of justice, rights, and human responsibility. His theory not only transformed psychological inquiry into ethical judgment but also generated discussions across education, sociology, political philosophy, and legal studies.
This volume seeks to examine the Kohlbergian Moral Development Theory in both its historical significance and its contemporary relevance by exploring the conceptual architecture of the six-stage model, the empirical methods through which Kohlberg investigated moral reasoning, and the philosophical assumptions that underlie his interpretation of human moral growth. Particular attention is devoted to the relationship between cognition and ethics, the universality of moral principles, and the role of social interaction in the formation of moral consciousness.
At the same time, no comprehensive engagement with Kohlberg can avoid the substantial critiques directed toward his work. Scholars such as Carol Gilligan challenged the theory's emphasis on justice-based reasoning, arguing for the importance of care, relationality, and contextual ethics. Cross-cultural researchers questioned the universality of the developmental stages, while contemporary psychologists have examined the limits of rational models of morality in light of emotion, intuition, and social identity. Rather than diminishing Kohlberg's importance, these debates demonstrate the extraordinary intellectual vitality of his contribution and its capacity to stimulate ongoing scholarly reflection.
The purpose of this book is therefore neither to celebrate nor to dismiss Kohlberg uncritically, but to situate his theory within the broader evolution of moral psychology. By revisiting his ideas through historical, empirical, and philosophical perspectives, this work invites you to reconsider how moral reasoning develops and how ethical understanding continues to shape human societies.
