In her book The Permeable Self, Barbara Newman—John Evans Professor of Latin, as well as English, Classics, and History at Northwestern University—explores the importance of coinherence in the medieval view of personhood. This is the concept that persons are profoundly interconnected, existing not in isolation but “in” each other. One illustration of this is the trope of exchanging hearts, whether between lovers or between female mystics and Christ.
The concept of our selves having such porous boundaries is perhaps an alien one to the contemporary American mind. But in this episode, Barbara discusses stories of heart transplant patients who—without knowing anything about the donors of their new hearts—began to take on personality traits of the donors. In a society where we often define personhood by its individuality and separateness, what do we make of instances such as these, which seem to bear out a medieval understanding of what it means to be human?
