A History of the Impossible: Carlos Eire on They Flew

Carlos Eire and Kirsten Macfarlane on October 29, 2025 at the University of Chicago's Swift Hall. Levitation. Bilocation. Witchcraft. Demonic Possession. Europe in the early modern era was simultaneously the site of Kepler, Newton, Copernicus–and of eyewitness accounts of levitating saints and nocturnal witches’ sabbats. In his history of the impossible, award-winning historian Carlos Eire mines the firsthand accounts and archival evidence of the miraculous and demonic. How did an increasingly skeptical and scientific culture account for events deemed impossible by its leading intellectuals? What does this say about the supposed boundaries between the natural and supernatural that marked the transition to modernity? In this lecture, Carlos Eire explores the major themes of "They Flew" and asks: what makes something impossible? And is there more to reality than meets the eye? University of Chicago Divinity School professor Kirsten Macfarlane offers a response and engages Eire in a conversation. --- This project was made possible through the support of In Lumine Tuo: Expanding and Sustaining the Catholic Intellectual Tradition Nationwide (grant ) from the John Templeton Foundation and the generous support of the University of Chicago Divinity School and the Workshop on the Early Modern World.
