This examination of a fundamental but often neglected aspect of the intellectual history of early modern Europe brings together philosophers, historians and political theorists from Great Britain, Canada, the United States, Australia, France and Germany. Despite the diversity of disciplines and national traditions represented, the individual contributions show a remarkable convergence around three themes: changes in the modes of moral education in early modern Europe, the emergence of new relations between conscience and law (particularly the law of the state), and the shared continuities and discontinuities of both Roman Catholic and Protestant moral culture in relation to their medieval past.
