In 1971, priest, theologian, and philosopher Ivan Illich wrote Deschooling Society, a plea to liberate education from schooling and to separate schooling from the state. On the occasion of the fiftieth anniversary of its publication, Ivan Illich Fifty Years Later looks at the theological roots of Illichs thought and the intellectual and ideological strands that contributed to his ideas.

Guided by the central question of how Illich reached the point of writing Deschooling Society, the book sheds light on how Illich produced a critique of schooling that can be defined by its eclecticism. Bruno-Jofre and Igelmo Zaldivar explore how this controversial book was framed by Illichs early neo-scholastic and anti-modern foundation, his discovery of St. Thomas through Jacques Maritain, and the existential turning points that influenced his public life and intellectual direction in moving from a critique of the Church as institution to a critique of schooling. Drawing from the interpretative theories of Quentin Skinner, Reinhart Koselleck, and William H. Sewell and from concepts such as educationalization, transnationality, and configuration, among other heuristic tools, the authors provide an original and cross-disciplinary analysis of Deschooling Society and its place in Illichs journey.
