How does moral change happen? What leads to the overthrow or gradual transformation of moral beliefs, ideals, and values? Change is one of the most striking features of morality, yet it is poorly understood. In this book, Cecilie Eriksen provides an illuminating map of the dynamics, structure, and normativity of moral change. Through eight narratives inspired by the legal domain and in dialogue with modern moral philosophy, Eriksen discusses moral bias, conflict, progress, and revolutions. She develops a context-sensitive understanding of ethics and shows how we can harvest a knowledge of the past that will enable us to build a better future.
