Prof. Carlos A. Casanova argues that religion—understood as a theological worldview affirming God as the rational creator—is not an enemy but an historical and structural ally of science, since the very rise, methods, and institutional homes of the sciences (from Plato and Aristotle through medieval universities to Galileo) developed within religious cultures that prized truth for its own sake.This lecture was given on December 3rd, 2025, at Purdue University.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speakers:A native of Venezuela, Carlos Casanova holds a law degree from the Catholic University Andrés Bello and a Ph.D. in philosophy from the University of Navarre, Spain.

Fr. Philip-Neri Reese argues that while grimdark fantasy (exemplified by George R. R. Martin) can be just as true artistically as Tolkien-style classic fantasy, it is necessarily less good in the fullest Thomistic sense because it structurally valorizes nihilism and hopelessness rather than ordering the imagination toward God and real moral hope.This lecture was given on October 16th, 2025, at University of Edinburgh.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events.About the Speakers:Fr.
