Simone de Beauvoir, Ethics of Ambiguity - Sacrifice, Usefulness, and Human Beings
This lecture discusses key ideas from the 20th century existentialist and feminist philosopher, novelist, essayist, and playwright Simone de Beauvoir's book, The Ethics of Ambiguity
It focuses specifically on her discussion at the end of the section "The Antinomies Of Action", which looks at the willingness of some people to justify sacrificing others for the sake of some conception of usefulness or utility in achieving some value they view as transcendent. De Beauvoir argues that "useful" is not an absolute term, and that one has to clarify the end that one is claiming justifies the sacrifice.

Simone de Beauvoir, Ethics of Ambiguity - Contempt For Humanity And For Individuals
This lecture discusses key ideas from the 20th century existentialist and feminist philosopher, novelist, essayist, and playwright Simone de Beauvoir's book, The Ethics of Ambiguity
It focuses specifically on the contempt for both humanity as a whole and for individual human beings that is displayed by some people in the use of their own freedom. She notes that this generally involves the reduction of persons to things, taking away their transcendence and viewing them only in their facticity or immanence.

Simone de Beauvoir, Ethics of Ambiguity - The Aesthetic Attitude - Sadler's Lectures
This lecture discusses key ideas from the 20th century existentialist and feminist philosopher, novelist, essayist, and playwright Simone de Beauvoir's book, The Ethics of Ambiguity
It focuses specifically on her analysis of what he terms the "aesthetic attitude" early on in part 3 of the work. This is a use of one's freedom that is inauthentic, because it adopts a detached contemplative stance towards the very history and situations one exists within, refusing to acknowledge that one takes a stance one way or another. She also highlights how this can be an even more acute problem for artists and writers.

Thomas Aquinas, Multiple Thomisms, and Christian Philosophy - Feast Of St. Thomas Lecture (part 6)
This is part 1 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.
