The Use of Philosophical Principles in Catholic Social Thought: The Case of Gaudium et Spes

By: Rev. Joseph W. Koterski, S.J.

Pope John Paul II’s social teachings make profound and sustained use of philosophical principles. This paper reviews his encyclicals on social teaching to show that, by the careful employment of philosophical concepts and the sorts of argument that are typical of the natural law tradition and of personalism, there can be adequate explanation and defense of the various claims that are important to Catholic Social Thought. The use of such philosophical principles allows these documents not only to appeal to the authority of the Church but also to provide arguments that are readily intelligible for broader audiences.
