Lawrence Kohlberg – Life, Career, and Famous Quotes

Learn about Lawrence Kohlberg (1927 – 1987), the American educator and psychologist known for his influential theory of moral development. Explore his biography, major contributions, stages of moral reasoning, critiques, and enduring legacy.

Introduction

Lawrence Kohlberg (October 25, 1927 – January 17, 1987) was a pioneering American psychologist and educator whose work transformed how we understand moral reasoning and ethical development. He extended and refined earlier ideas (notably those of Jean Piaget) by proposing a structured sequence of stages through which moral judgment matures. Kohlberg's research has had deep influence in education, philosophy, psychology, and ethics pedagogy.

His ideas invited both admiration and critique—but regardless, they sparked decades of further research into how people think about right and wrong, and how we might design education systems to nurture more just, principled thinkers.

Early Life and Family

Lawrence Kohlberg was born in Bronxville, New York, on October 25, 1927.

His parents separated when he was about four years old, and formally divorced when he was fourteen.

He attended Phillips Academy in Andover, Massachusetts for his high school years. U.S. Merchant Marine, and was involved in missions to transport Jewish refugees from Romania to Palestine.

Youth, Education & Academic Formation

After his Merchant Marine service, Kohlberg enrolled at the University of Chicago in 1948, earning his Bachelor of Arts degree in just one year (thanks in part to credit by examination). Ph.D. in psychology in 1958.

Kohlberg’s doctoral research involved studying how children reason about moral dilemmas—an area only sparsely explored until then.

His earliest academic appointment was as Assistant Professor of Psychology at Yale University from 1958–1961. University of Chicago in 1962 as part of its Psychology and Human Development department. Harvard University (Graduate School of Education) as Professor of Education and Social Psychology, where he remained for the rest of his career.

Career and Contributions

Kohlberg is best known for theory of moral development, but he also made contributions in moral education, empirical psychology, and applied ethics.

Theory of Moral Development

Kohlberg’s key insight was that moral judgment develops through six stages, which are grouped into three levels (preconventional, conventional, postconventional).

The six stages are:

He used moral dilemmas—prominently the “Heinz dilemma” (should Heinz steal a drug to save his dying wife?)—to probe participants’ moral reasoning. what decision people made, but why they made it.

Kohlberg held that moral reasoning (i.e. judgment) is distinct from moral behavior: one might reason at a high moral stage but not always act accordingly (because of situational constraints, emotions, etc.).

Moral Education & “Just Community”

Kohlberg sought to translate theory into practice by designing moral education methods. His three notable approaches were:

1. Moral Exemplars – using biographies or stories of morally exemplary figures (e.g. Lincoln, Gandhi) to stimulate moral reflection and reasoning.

2. Dilemma Discussions – structured classroom discussion around moral dilemmas, where students debate and reason, ideally guided to move toward more advanced moral reasoning.

3. Just Community Schools – creating school environments with democratic participation from students and teachers in rule-making, deliberation, and justice processes, thereby embedding moral reasoning into daily life.

He believed that moral development should be an explicit aim of education, not merely a byproduct.

Other Work & Legacy

Kohlberg's scholarship also included numerous essays and books, including Essays on Moral Development, Vols. I & II, The Philosophy of Moral Development, and The Psychology of Moral Development.

He founded the Center for Moral Education and Development at Harvard in 1974, which became a hub for research, training, and applied work around ethics and education.

In empirical rankings of psychological eminence, Kohlberg was ranked among the top psychologists of the 20th century.

Historical Milestones & Context

Kohlberg’s work came during a period when psychology was strongly behaviorist or psychoanalytic; his emphasis on reasoning, moral philosophy, and structural stages was distinctive.

He extended Piaget’s work on moral judgment (which largely addressed children) into adolescence and adulthood, arguing that moral reasoning continues to evolve across the life span.

His ideas entered education policy, ethics training, and curriculum design, especially during the era of increased interest in “character education” in schools.

Kohlberg’s untimely death in 1987 was in itself controversial. On January 17, 1987, he parked his car near the Boston Harbor and, leaving his wallet in the car, disappeared into the icy waters. His body was recovered later.

Some biographical sources note that over the years Kohlberg had suffered health problems tracing back to a parasitic infection contracted during his fieldwork in Belize, as well as emotional struggles such as depression.

Legacy and Influence

Lawrence Kohlberg’s influence is broad and multi-layered:

• His theory of moral development remains foundational in psychology, ethics, philosophy, and education curricula worldwide.

• He mainstreamed the idea that moral reasoning can be empirically studied and categorized in structured stages.

• Many educational programs adopted moral dilemma discussions or “character education” frameworks influenced by Kohlberg’s ideas.

• His frameworks triggered extensive critique and further theory-building—especially by those who perceived gaps, such as Carol Gilligan (on care ethics), cultural relativists, and proponents of situational ethics.

• Even critics acknowledge Kohberg’s work pushed moral psychology into serious scientific inquiry.

Though not everyone achieves the highest stages of moral reasoning according to Kohlberg, his model remains a powerful lens through which to examine moral growth, education, and social justice.

Personality, Methods & Style

Kohlberg was intellectually rigorous, deeply philosophical, and motivated by a vision of fostering principled moral reasoning in individuals and institutions.

His research method was qualitative and developmental, using interviews, hypothetical dilemmas, and analysis of reasoning rather than purely statistical “yes/no” measures.

He insisted on probing why someone made a decision—not just what decision—believing that moral reasoning reveals deeper structure in the human mind.

Kohlberg’s tone in writing was philosophical, reflective, and ambitious: he sought to bridge psychology and ethics, and believed that moral development was both a scientific and moral imperative.

Famous Quotes of Lawrence Kohlberg

Here are some well-known quotations attributed to Kohlberg:

“All individuals in all cultures use the same thirty basic moral categories, concepts, or principles, and all individuals in all cultures go through the same order or sequence of gross stage development, though they vary in rate and terminal point of development.”

“The first stage of moral development is characterized by obedience and avoiding punishment.”

“I believe that moral education must … take the form of dialogue and reflection, not admonition or indoctrination.” (paraphrased from his educational philosophy)

“Others are vulnerable to moral myopia—or the simple inability to see moral issues clearly.” (often cited in moral reasoning literature)

Because Kohlberg’s writing is dense and academic, these quotes are often simplified or paraphrased in secondary sources.

Lessons from Lawrence Kohlberg

From Kohlberg’s life and work, we can draw several lessons:

1. Moral reasoning can grow
   Human moral reasoning is not fixed; through challenge, discussion, and reflection, people can advance their understanding of justice, ethics, and fairness.

2. Ask “why” not just “what”
   To understand moral behavior, probing the reasoning behind choices yields deeper insight than judging the choice itself.

3. Education should foster deliberation, not dogma
   Kohlberg’s pedagogical approach emphasizes guided discussion, not indoctrination—a valuable principle for teaching ethics.

4. Complexity, humility, and openness
   His work shows that moral life is complex—few reach the highest ideals, and we must stay humble about cultural, situational, and psychological constraints.

5. Theory invites critique and growth
   Kohlberg’s framework stimulated alternative perspectives (e.g. care ethics, cultural contexts), suggesting that advancing understanding requires dialogue across viewpoints.

Conclusion

Lawrence Kohlberg remains one of the towering figures in moral psychology and educational ethics. His systematic theory of moral development has shaped how we think about children’s moral growth, how to teach ethics responsibly, and how societies can foster more principled reasoning.

Though not without criticisms and limitations, Kohlberg's legacy is one of aspiration: to help individuals and communities cultivate deeper, more reflective, just responses to moral dilemmas.
