In this seminar, students will read, analyze, and discern continuities and discontinuities in Catholic Social Thought from the late 19th century to the present. Lectures, seminar reports, and discussion will focus on original sources (encyclicals and other magisterial documents), beginning with Rerum novarum (1892) and concluding with Caritas in veritate (2009) and Evangelii Gaudium (2013). This intensive course is multi-disciplinary, since this tradition of social thought overlaps several disciplines in the contemporary university including political science, political philosophy, law, economics, theology, and history.
