How has Catholic higher education in the U. S. changed since Vatican II? Evolving in three historical periods in the last six decades, Catholic institutions have experienced tumultuous upheaval and radical transformation, becoming more secular or "catholic" in orientation and less orthodox or "Catholic." This essay discusses both the positive and problematic developments of these changes, and it concludes with several proposals for a Catholic core curriculum and a revitalized intellectual tradition. ? 2012 Springer Science+Business Media New York.
