Dr. Jennifer Frey discusses St. Thomas Aquinas's understanding of sin as a privation of good and a failure to achieve one's proper end. Aquinas attributes the causes of sin to human nature's fallen state, resulting in a darkened intellect, disturbed passions, and a disordered will, which can lead to sins of ignorance, weakness, or malice.This lecture was given on February 15th, 2024, at The University of Tulsa.For more information on upcoming events, visit us at thomisticinstitute.org/upcoming-eventsAbout the Speaker: Jennifer Frey is the inaugural Dean of the Honors College and Professor of Philosophy at the University of Tulsa.
