This volume is a collection of Josef Pieper’s famous treatises on the three theological virtues of faith, hope, and love. Each of these treatises was originally published as a separate work over a period of 37 years. On Hope was written in 1934 in response to the despair of that era. On Faith was derived from a series of lectures he gave in the late 1950s and early 1960s. His most difficult work, one that he struggled with for years and almost abandoned—was On Love. Pieper felt that it was the most important book he had written. He discusses not only the theological virtue of caritas-agape, but also of eros, sexuality, and even “love” of music and wine.
