Josef Pieper (1904-1997) was an influential German Catholic philosopher, scholar, and author at the forefront of the Neo-Thomistic wave in twentieth century Catholic philosophy. Among his most notable works are The Four Cardinal Virtues: Prudence, Justice, Fortitude, Temperance; Leisure: the Basis of Culture; The Philosophical Act and Guide to Thomas Aquinas (published in England as Introduction to Thomas Aquinas).
Pieper studied philosophy, law and sociology at the universities of Berlin and Münster. After working as a sociologist and freelance writer, he became ordinary professor of philosophical anthropology at the University of Münster, and taught there from 1950 to 1976. As professor emeritus he continued to provide lectures until 1996. With his wife Hildegard he translated C.S. Lewis, The Problem of Pain, into German (Über den Schmerz, 1954) with an Afterword "On Simplicity of Language in Philosophy". A symposium to celebrate his 90th birthday was held in Münster in May 1994; the papers read there were published as Aufklärung durch Tradition ("Enlightenment through Tradition" in 1995. In 2010 a symposium was held in Paderborn on "Josef Pieper's and C. S. Lewis's View of Man", with papers published in Wahrheit und Selbstüberschreitung ("Truth and Self-Transcendence").
In 1981 Pieper received the Balzan Prize in Philosophy; in 1987 he was awarded the State Prize of the state of Nordrhein-Westfalen. In 1990, he received the Ehrenring of the Görres-Gesellschaft.
