Today’s pluralist and multicultural society raises questions about how to teach religiously and ethnically diverse students in Catholic schools. A Catholic Philosophy of Education addresses these challenges by examining the documents from the Roman Congregation for Catholic Education alongside the writings of Jacques Maritain and Bernard Lonergan. Mario D’Souza proposes a contemporary formulation for a Catholic philosophy of education in which the ideals of Catholicism form the basis for the mission of the Catholic school. Drawing on the Church’s educational documents, and informed by Maritain and Lonergan, D’Souza explains how the unifying anthropology of Catholic education enables Catholic schools to serve amidst diversity by avoiding the extremes of religious exclusivism and fundamentalism, on the one hand, and relativism and individualism, on the other. He explores the aims of Catholic schools in relation to students, teachers, and society, and the relationship between goodness, discipline, and knowledge. He argues that students must be educated for personal and communal freedom and authenticity, and to strive for the common good, suggesting how a Catholic philosophy of education can provide the framework for such personal and communal transformation. Essential reading for new and experienced Catholic educators, A Catholic Philosophy of Education demonstrates that Maritain and Lonergan have much to offer in service of an education that is liberating, instructive, illuminating, and integrative.
