Questions addressing people's moral lives, similarities and differences in the moral concepts of cultural groups, and how these concepts emerge in the course of development are of perennial interest. In a globalizing world, addressing what is universal and what is culturally distinctive about moral development is pressing. More than ever, well-substantiated knowledge of diverse peoples' moral compasses is needed. This book presents the cultural-developmental theory of moral psychology, findings from numerous countries, and four instruments for conducting cultural-developmental research. The central thesis is that humans are born with a shared moral heritage and that, as we develop from childhood into adulthood, we branch off in diverse directions shaped by culture - resulting in novelty and contention. An international group of eminent and cutting-edge scholars from anthropology, psychology, and linguistics addresses this timely topic and explores how gender, social class, and 'culture wars' between liberals and conservatives play into moral development across cultures.
