The Degrees of Knowledge

Jacques Maritain (1882 – 1973), was a French Catholic philosopher. Raised Protestant, he was agnostic before converting to Catholicism in 1906. An author of more than 60 books, he helped to revive Thomas Aquinas for modern times, and was influential in the development and drafting of the Universal Declaration of Human Rights. Pope Paul VI presented his "Message to Men of Thought and of Science" at the close of Vatican II to Maritain, his long-time friend and mentor.

Ralph McInerny (1929–2010) was Michael P. Grace Professor of Medieval Studies and director emeritus of the Jacques Maritain Center, University of Notre Dame. He was the author of numerous works in philosophy, literature, fiction, and journalism, including The Very Rich Hours of Jacques Maritain, Characters in Search of Their Author, and his autobiography, I Alone Have Escaped to Tell You, all published by the University of Notre Dame Press.
