The Thomistic Institute

Prof. Michael Dauphinais contends that modern Christians, formed by empiricism, individualism, and a this‑worldly hope that easily turns to despair, especially need the Eucharist because it is the concrete, sacramental way Christ draws us into the Trinitarian communion for which we were created, making his paschal mystery present and reproducing his own filial relation to the Father in us. This le...

Prof. Gavin D’Costa explains how, since Vatican II, the Catholic Church has rethought its relationship to Judaism by affirming the enduring validity of God’s covenant with the Jewish people, recovering the Church’s identity as a fundamentally Jewish–Gentile reality, and opening unresolved but fertile questions about mission, ecclesiology, and antisemitism. This lecture was given on October 9th, 20...

Prof. Michael Root argues that, in Catholic theology, we are saved wholly by the unmerited grace of Christ, and that this grace brings us into a Spirit‑given life of faith, hope, love, and morally significant works, so that eternal life is at once pure gift and, in a secondary sense, a “merited destiny.” This lecture was given on September 9th, 2025, at North Carolina State University.

Fr. Dominic Langevin defends the Catholic priesthood as a divinely willed, sacramental system of mediation in which ordained men, configured to Christ the High Priest, bestow God’s gifts on the faithful and offer their prayers and sins to God, thereby promoting both God’s glory and the sanctification and dignity of the Church. This lecture was given on November 10th, 2025, at West Virginia Univers...

Fr. John Baptist Ku unpacks St. Thomas Aquinas’s doctrine of predestination, showing how God’s universal salvific will, efficacious grace, and real human freedom coexist without collapsing into Calvinist double predestination or Pelagian self-salvation. This lecture was given on November 22nd, 2025, at Dominican House of Studies. For more information on upcoming events, visit us at thomisticinstit...

Prof. Thomas Osborne clarifies how, for Aristotle and St. Thomas Aquinas, the distinctive immateriality of human intellectual knowledge grounds a philosophical case for the soul’s immortality, going beyond today’s narrower “problem of consciousness.” This lecture was given on October 16th, 2025, at University of Connecticut. For more information on upcoming events, visit us at thomisticinstitute.o...

Prof. Marshall Bierson uses Aristotle’s distinction between work, play, and deeper “energetic” activities to argue that friendship and contemplation uniquely allow us to “rest” in what is truly good and meaningful, and then shows how Aquinas radicalizes this by making both contemplation and friendship with God the heart of human fulfillment. This lecture was given on November 20th, 2025, at Cornel...

Dr. Erik Dempsey explains how St. Thomas Aquinas sees pleasure as a natural and God-given part of the good life, one that both signals our true human ends and yet must be disciplined by temperance in a fallen world. This lecture was given on December 4th, 2025, at Southern Methodist University. For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events . About the...

Prof. Timothy O’Connor examines why an all-loving, omnipotent God permits horrendous suffering and explores how, within a Christian framework, such evils can be “defeated” and taken up into the communion of saints as part of our eternal union with God. This lecture was given on December 3rd, 2025, at University of Scranton. For more information on upcoming events, visit us at thomisticinstitute.or...

Sr. Mary Madeline Todd draws upon Aristotle, St. Thomas Aquinas, and friendship with Christ in order to show that sharing a common journey and life, together with mutual self-gift, turns everyday relationships into true, virtuous friendships that enable us not merely to survive but to thrive in happiness with God and one another. This lecture was given on November 27th, 2025, at Thomistic Institut...

Dr. R. J. Snell analyzes our “burnout society” as an achievement-obsessed culture that drives people to anxiety, depression, and exhaustion by demanding endless self-optimization while starving them of leisure, contemplation, and a meaningful narrative for their lives. This lecture was given on December 8th, 2025, at University of Pennsylvania. For more information on upcoming events, visit us at...

Dr. Kevin Kambo argues that our culture has moved from a “dictatorship of relativism” to a “tyranny of pathos,” in which appeals to hurt feelings and empathy displace reasoned deliberation about truth, justice, and human nature. This lecture was given on October 23rd, 2025, at Fordham University. For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events . About th...

Prof. Steven Jensen argues that right and wrong are not just a matter of opinion by defending moral realism over moral relativism, showing that moral truths are grounded in human nature and goals rather than mere subjective attitudes. This lecture was given on November 13th, 2025, at Fordham University. For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-events . A...

Fr. Jacques Benoit-Rauscher explores whether the Catholic Church is truly anti-capitalist by clarifying how Catholic social doctrine distinguishes legitimate market structures from the problematic “spirit of capitalism” and proposing a prudent, Thomistic way of living faithfully within contemporary economic systems. This lecture was given on October 30th, 2025, at University of Galway. For more in...

Prof. George Corbett examines how Dante’s vision of Christian wisdom, politics, and philosophy stands in deep harmony with Aquinas and Pope Leo XIII’s Leonine Thomistic revival, against Etienne Gilson’s charge that Dante shattered both Thomism and Christendom. This lecture was given on January 20th, 2026, at Dominican House of Studies. For more information on upcoming events, visit us at thomistic...

Prof. Jonathan I. Lunine presents his life as a planetary scientist and Catholic convert as a lived example of the harmony between faith and science, then highlights two priest‑scientists—Georges Lemaître and Gregor Mendel—whose foundational work on the Big Bang and genetics shows that Catholic belief has stood at the center of modern scientific revolutions. This lecture was given on February 20th...

Dr. Timothy P. Flanigan, M.D., presents Catholic faith and medicine as profoundly harmonious, showing how Christ’s person‑to‑person healing, the Church’s hospital tradition, and a “culture of life” can and must be lived inside today’s secular, therapeutically focused healthcare system—precisely where pressures over abortion, assisted suicide (MAID), and gender interventions create the sharpest con...

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 r...

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. This lecture was given on January 15th, 2025, at Dominican House of Studies. For more information on upc...

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. Th...

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 Un...

Prof. Lee Oser portrays the Inklings—and especially J.R.R. Tolkien and C.S. Lewis—as a countercultural circle of Christian writers and scholars whose friendship, medieval learning, and shared experience of war grounded a robust Christian imagination that resisted modern secularism by telling better, theologically rich stories. This lecture was given on October 28th, 2025, at United States Military...

Prof. Lee Oser argues that Christian humanism—the “radical middle” between secularism and sectarianism—offers the best key to Shakespeare’s plays, showing how Julius Caesar and Hamlet dramatize our tragic ignorance about the fate of the soul and the limits of pagan and early modern attempts to know ourselves without fully knowing God. This lecture was given on October 16th, 2025, at University of...

Prof. Joshua Hochschild shows how Dante’s Paradiso offers a philosophically rich, Thomistic, and Neoplatonic vision of the cosmos in which goodness, truth, beauty, and peace name both God’s own life and the ordered, participatory structure of creation that our rational desire seeks to know and love. This lecture was given on November 13th, 2025, at University of Louisiana at Lafayette. For more in...

Prof. George Corbett presents Dante’s Divine Comedy as a transformative “journey of desire” in which the passionate intellect—shaped by Virgil (reason) and Beatrice (grace)—leads the sinner from the dark wood of sin and ignorance through Hell and Purgatory to the ordered love and beatific hope of Paradise. This lecture was given on November 20th, 2025, at Trinity College Dublin. For more informati...
