What follows is an interview with William Damon and Anne Colby, pioneers in the fields of moral psychology and education. Throughout their careers, they have studied, moral identity, moral ideals, positive youth development, purpose, good work, vocation, character development in higher education, and professional responsibility. In their words, they are interested in the 'best of humankind'--not only the competencies, but also the character necessary for living a good life--not only for the sake of the individual, but also for society. They have received numerous academic and civic awards and honors. Their publications include "Some Do Care," "Greater Expectations," "Educating Citizens," "The Path to Purpose," and most recently, "The Power of Ideals"--in addition to editing, for example, "New Directions for Child and Adolescent Development" and "The Handbook of Child Psychology." As a married couple, their vocational journeys have mostly been separate, but have always complemented each other and sometimes converged. This interview asks about reflections on their careers, their own sense of purpose, their greatest contributions, current needs in our field, and advice to emerging scholars.
