Prof. Mats Wahlberg argues that “necessitarian universalism”—the claim that hell is metaphysically impossible and that God must save all rational creatures—is incompatible with core Christian metaphysical commitments, and he develops three Thomistic arguments to show that the possibility of eternal damnation follows from God’s wisdom, respect for created natures, and desire for truly free self-gift.

Prof. Thomas Osborne explains reprobation and the permission of sin in Thomas Aquinas as the asymmetrical counterpart to predestination, where God positively causes the grace and merits leading the elect to glory but only permits the sins of the reprobate without ever willing or causing moral evil, thus safeguarding both divine justice and human responsibility.​

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. He is now a lecturer at the University of Florida’s Hamilton Center.

He is a native of Venezuela. 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”). His scholarly competence also includes philosophy of science, epistemology, philosophy of mind, medieval philosophy, and contemporary European philosophy. He has published nine books and numerous scholarly papers.
