Prof. Lawrence M. Principe argues that the supposed “war” between science and faith is largely a modern myth, constructed in the late 19th century by figures like John William Draper and Andrew Dickson White for personal, political, and ideological reasons, then amplified by secularizers, technocratic utopians, and bad theology (especially “God‑of‑the‑gaps” arguments and naive literalism) on the religious side. This lecture was given on January 28th, 2026, at New York University. For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events . About the Speakers: Prof. Principe’s research focuses on the Medieval and early modern periods, with emphasis on the history of science (especially alchemy and chemistry), and the science-religion dynamic down to the present day.

Prof. Jonathan Lunine offers a personal and intellectual witness that one can be both a serious planetary scientist and a committed Catholic, describing his journey from Jewish upbringing and “cradle astronomer” to baptism and then to public advocacy against the supposed science–faith conflict.

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.

There he served as an attorney for the Office of the Attorney General of Venezuela and for the Venezuelan Congress, and as an assistant to a Justice of the Venezuelan Supreme Court in the early 90s. Afterward he was a professor of the Graduate Studies in Philosophy at the Universidad Simón Bolívar and Chair of the Program. In 2002, threatened by the Chavista regime, he was forced to leave the country. During his first stay in the USA, professor Casanova was a visiting scholar at Boston University and a senior research associate at the Jacques Maritain Center, University of Notre Dame, where he worked with Ralph McInerny. During this time he married Laura Ternan with whom he has 5 children. In 2005 he went to Chile, to work at the International Academy of Philosophy with professor Josef Seifert. Afterward he taught at Universidad Santo Tomás in Chile, and at the School of Law of the Pontifical Catholic University of Chile. In 2020-2022 he opposed the abortionist movement and the attempts to introduce comprehensive sexual education during the early years of basic school. These efforts led to him receiving in 2022 the National Award bestowed by the “Network for Life and the Family.” Due to the Marxist turn of the country, the Casanova family decided to leave Chile and migrate again, back to the United States in 2022. Professor Casanova’s work focuses on metaphysics, political and social philosophy, ethics, and classical Greek philosophy. He has endeavored to dismantle the black legend that hides the achievements of Christianity in the Spanish American empire and in the Latin Christendom (so called “Middle Ages”).
