This article introduces a special section on moral development. We claim that the field is now undergoing a resurgence of theoretical and methodological innovation after the eclipse of paradigmatic moral stage theory. Although research on prosocial development, moral emotions, and social domain theory has sustained interest in moral development, recent additional trends have contributed to its resurgence. This includes research in neuroscience, sociobiology, and social psychology; broad interest in moral-character education and virtues; and the appearance of recent handbooks and special journal issues. We review 3 broad possible future themes (early development, self and personality, and culture) of moral development research and introduce a set of new contributions in this special section as examples.
