The Sensory and Beyond
What do we and how can we know beyond what we can sense in the physical world? Contemplate Aquinas’ thoughts on why the philosophical limit of our sensations is cause for optimism, whether slothfulness might actually be a virtue, and how suffering is foundational to the development of our moral lives.

What do we and how can we know beyond what we can sense in the physical world? Contemplate Aquinas’ thoughts on why the philosophical limit of our sensations is cause for optimism, whether slothfulness might actually be a virtue, and how suffering is foundational to the development of our moral lives.
The comprehensive and systematic character of Thomas Aquinas’ thought has for centuries informed inquiry into questions of human dignity, freedom, economic development, work, poverty, the environment, and other issues of global significance. Celebrate the 800th anniversary of the birth of Thomas Aquinas, exploring the ongoing importance of his thought to contemporary cultural, philosophical, and theological discussions. In gathering many of the most accomplished contemporary scholars of Aquinas’ thought from throughout the world working on themes in Ethics, Metaphysics, Epistemology, Anthropology, Political Theory, Christology, Trinitarian Theology, Sacramental Theology and Ecclesiology, among others, this series promotes fruitful interchange of diverse perspectives on the importance of Aquinas in the world today.

Meet the Speaker: Roberto Zambiasi

Roberto Zambiasi is a postdoctoral researcher at the De Wulf-Mansion Centre within Professor Russell Friedman’s project “Studying Medieval Hylomorphism Whole: Hylomorphic Theory in Intellectual Context, 1250-1400”. His research for the project deals with topics in late 13th- and early 14th-century hylomorphism, with a special focus on the issue of the quantitative structure of substantial forms.
Before coming to Leuven, Zambiasi obtained his PhD through a cotutelle agreement between the University of Turin in Italy (FINO Consortium) and the École Pratique des Hautes Études (EPHE) in Paris. His PhD thesis explores the 13th- and 14th-century Latin debate on the so-called issue of minima sensibilia, i.e. the problem of the divisibility of sensible qualities through the division of matter, as discussed by Aristotle in De sensu et sensato 6, 445b3-446a20.
Zambiasi’s research interests include conceptions of substantial forms and substantial change in Scholastic Aristotelian natural philosophy, later medieval theories of perception, and the medieval Latin commentary tradition on Aristotle’s libri naturales (especially the De sensu).
Meet the Speaker: Derek McAllister

Derek McAllister is an Instructor of Philosophy at Towson University and Loyola University Maryland in Baltimore, Maryland. He specializes in History of Philosophy (esp. Medieval), History of and Philosophy of Psychiatry (esp. Depression, Human Flourishing), Virtue Ethics, and Medical Ethics. In addition, his curiosity spills over into areas like Philosophy of Religion, Philosophy of Emotion, Epistemology, and Existentialism.
A firm proponent for a holistic and wide-ranging education, and sharer of forgotten or unknown treasures (see my resources page), he is passionate about teaching Philosophy. He has taught at the college and university level since 2014. Learning what makes us flourish and live well has long held his fascination, and he tries to share that wonder with my students. His dissertation has focused on prima facie historical predecessors to depression–e.g., acedia, tristitia, noche oscura, melancholia, Tungsindighed, etc. He has been especially formed by the writings of Thomas Aquinas, Søren Kierkegaard, & St. John of the Cross. He has also had the privilege to shadow a Clinical Psychologist at the Waco Family Medical Center, and he received a Cross-Training Grant funded by the John Templeton Foundation for the 2019-2020 academic year to work in Baylor’s Psychology and Neuroscience Department for the purpose of gaining a deeper understanding of depression from a psychological, psychiatric, and neuroscientific perspective. Outside of philosophy, he enjoys dabbling in disciplines such as history, genealogy, philology & languages, & theology. Outside of academia, he loves traveling, watching football, and hiking or playing soccer with his son.
