Hildegard of Bingen was a 12th century abbess, polymath, and composer whose work spanned visionary theology, philosophy, cosmology, medicine, botany, and music. Her extraordinary intellectual accomplishments belie her humble claim to be โjust a womanโ. Josh and Ray explore her life and thought with Christina Van Dyke from Columbia University, author of A Hidden Wisdom: Medieval Contemplatives on Self-Knowledge, Reason, Love, Persons, and Immortality.
