Thomas Aquinas, Multiple Thomisms, and Christian Philosophy - Feast Of St. Thomas Lecture (part 5)
This is part 5 of the recording of the invited inaugural Feast Day Of Saint Thomas lecture given at Mount Angel Abbey and Seminary. The full recording includes my lecture, Thomas Aquinas, Multiple Thomisms, and Christian Philosophy, a response by associate dean and professor Justin Shaun Coyle, and my answers to his and others' questions.
Thomas Aquinas' works, thought, and approach have been viewed at times as an exemplar for Christian philosophy by many. His influence in Catholic circles in some times was massive and practically unavoidable, while in others Thomism was marginalized. In this talk, I focus on one period in which attentive engagement with Thomas Aquinas' thought, taking form as various and often rival Thomisms, was at a peak, an era centered by the 1930s Christian philosophy debates. I outline a narrative that starts with the Thomist revival in the late 19th century, discusses some key positions staked out during the modernist crisis and the 1930s debates, and takes us up to our own times. I bring the lecture to a close by providing a few suggestions for productively engaging, interpreting, and incorporating the insights and spirit of Saint Thomas.

Jean-Paul Sartre, No Exit - Traps, Webs, and Proposed Solutions - Sadler's Stories
This lecture discusses the French Existentialist philosopher, Jean-Paul Sartre's play, No Exit, and focuses on the various ways in which the three characters attempt to find some manner of making their situation, trapped with each other for eternity, livable for themselves. Inez Serrano speaks of the situation as one beset with traps, and Joseph Garcin uses the metaphor of webs, but they do consider possible solutions, only to find that none of them will work in the long run.

She also seems to have more insight into their situation and less illusions about how they can make it liveable for eternity

Jean-Paul Sartre, No Exit - Themes, Characters, and Setting - Sadler's Stories
This lecture discusses the French Existentialist philosopher, Jean-Paul Sartre's play, No Exit, and focuses on the setting of the work, which is a particular version of hell where some of the dead, specifically three people, Joseph Garcin, Inèz Serrano, and Estelle Rigault, are condemned to be for eternity. Each of the three portrays or betrays themselves as being a certain type of person, and they will attempt to find ways to exist within the space together, unsuccessfully, since in some sense, "hell is other people".
