Self-Determination Theory (SDT) is an empirically based organismic theory of human motivation, development, and well-being that shares many points of interest with the fields of moral development and moral education. Yet, SDT has been largely disconnected from these fields so far. How can we define and empirically assess autonomous moral motivation? How is moral autonomy achieved in the course of development? And what are the relationships between leading a moral life and happiness? These questions have been occupying moral psychologists and educators for a long time. They are focal for SDT, as well. This special issue highlights various lines of intersection between SDT, morality and education. Contributions either expand SDT into the moral domain or incorporate elements of SDT into moral theory with the ultimate goal of integrating fields that inherently belong together.
