This paper examines the "Populorum Progressio," Pope Paul VI's 1967 encyclical on the "development of peoples," for a condensation of the chief tenets of Catholic social thought and for curricular guidelines. The author takes the word "development" to mean the concrete realizations of justice and peace. Fundamental education for peace and justice should address three major topics: The person (nature and character; potential or vocation); the person in community (institutions, order, and justice); and the person in culture and history (underpinnings for the conceptions and practices of institutions). The paper then discusses the general dimensions of these topics and examines how the curriculum of the Pulse Program at Boston College attempts to engage them. The basic idea of the Pulse Program is that students receive academic credit for participation in off-campus field projects which have a social action/social service orientation in coordination with a specially designed course. Examples include tutoring and recreation programs for disadvantaged children, public interest research and lobbying, hot lines, services to the elderly and hospitality programs for homeless men and women.
