2026-02-0513:22

This lecture discusses key ideas from the Utilitarian philosopher, Jeremy Bentham's work, Offenses Against Oneself, a posthumously published part of his Introduction to the Principles of Morals and Legislation. Here we examine the motive of antipathy, which means feeling pleasure in someone else's pain or feeling pain in someone else's pleasure in Bentham's work, and the role it plays in much of the prohibition or punishment of same-sex relationships.

Jeremy Bentham, Offenses Against Onself - Same Sex Relations And Depriving Women

2026-02-0415:04

This lecture discusses key ideas from the Utilitarian philosopher, Jeremy Bentham's work, Offenses Against Oneself, a posthumously published part of his Introduction to the Principles of Morals and Legislation. Here we examine some of the arguments that were being made in favor of prohibiting or punishing male-male sexual relationships on the basis that allowing them would in effect deprive women of their opportunities or even rights to enjoy male-female sexual relationships. Bentham examines each of the arguments in turn and exposes the weaknesses of them.

Jeremy Bentham, Offenses Against Onself - Common Reasons To Punish Same Sex Relations

2026-02-0114:02

This lecture discusses key ideas from the Utilitarian philosopher, Jeremy Bentham's work, Offenses Against Oneself, a posthumously published part of his Introduction to the Principles of Morals and Legislation. Here we examine some of the common reasons people give in his times and society for prohibiting or punishing male-male sexual relationships and activity. He considers first whether there is any harm caused, then whether it is an "offense against the peace" in any manner, and then whether male-male sexual activity is "enervating" that is, weakening to those who engage in it.

From The Eight Capital Vices To The Seven Deadly Sins - Poets, Mystics, and A Few Questions

2026-01-3014:05

In this invited lecture at Marist College, hosted by the Catholic Studies Program as part of their Marcelin Lecture Series, I narrate some of the key points and developments in the story of how we ended up with the current list of the Seven Deadly Sins, which are: Gluttony, Lust, Greed, Sloth, Wrath, Envy, and Pride. Originally, these start out as the Eight Capital Vices, a list which includes sadness, acedia, and vainglory, and which does not include envy. So, how did we end up with the list we know today? The story involves Christian monks in the Egyptian desert, Benedictine monks, a reluctant pope, poets, scholastic professors, confessors, and mystics, and ranges over a millennium of thinkers and texts. In the process, I discuss some of the key players: Evagrius Ponticus, John Cassian, Gregory I, Alcuin, Peter Lombard, Thomas Aquinas, and Dante Alighieri This portion of the talk discusses the treatments of the seven deadly sins by poets ranging from Prudentius to Chaucer and Dante, and by mystics like St. John of the Cross. We also conclude by examining a few additional topics raised by questions from the audience.

Soren Kierkegaard's Philosophical Fragments As Gilsonian Christian Philosophy - Sadler's Lectures

2026-01-2433:25

This is the recording of my presentation of my paper, "Kierkegaard’s Philosophical Fragments as Gilsonian Christian Philosophy," during the International Etienne Gilson Society satellite session at the American Catholic Philosophical Association 2015 conference. The recording also includes some lively discussion in the Q&A portion following my reading of the paper. In the paper, I discuss key features of Gilson's conception of Christian philosophy developed during the 1930s debates about the topic, examine why Kierkegaard would seem to be an unlikely prospect for Gilsonian Christian philosophy, but then argue that Kierkegaard's work Philosophical Fragments actually does fit Gilson's conception of Christian philosophy quite well.

Thomas Aquinas Summa Theologiae - Does Love Wound The Lover? - Sadler's Lectures

2026-01-2211:23

This lecture discusses key ideas from the medieval Christian philosopher and theologian Thomas Aquinas' Summa Theologiae, 1st part of the 2nd part, question 28 "The Effects Of Love", and examines his discussions in article 5, which centers on a question raised not only by literary tropes but also by the Song of Songs. Does the passion of love in some way wound or harm the lover? Thomas notes that love produces a "melting" or receptiveness in the lover, which if the object of love is present can lead to enjoyment, but if not can lead to strong desire and to the sadness of languor.

Thomas Aquinas Summa Theologiae - Zeal As An Effect Of Love - Sadler's Lectures

2026-01-2115:13

This lecture discusses key ideas from the medieval Christian philosopher and theologian Thomas Aquinas' Summa Theologiae, 1st part of the 2nd part, question 28 "The Effects Of Love", and examines his discussions in article 4, which centers on the question of "zeal" (zelus in Latin, zēlos and zēlotupia in Greek) and whether it is or is not an effect of love. The answer to this depends on what sense of "zeal" we have in mind, and that depends on whether the person feel love of concupiscence or love of friendship.

Thomas Aquinas Summa Theologiae - Ecstacy As An Effect Of Love - Sadler's Lectures

2026-01-1911:37

This lecture discusses key ideas from the medieval Christian philosopher and theologian Thomas Aquinas' Summa Theologiae, 1st part of the 2nd part, question 28 "The Effects Of Love", and examines his discussions in article 3, which centers on whether or not ecstasy is something that love produces as an effect. For Thomas as it turns out, it all depends on how we understand that term. If we have in mind an affective state that in some way sets them outside their normal rational faculties, then this does occur in some cases. But if we mean something more literal, being placed outside ourselves in some way, ecstasy is indeed an effect of love, in particular the love of friendship To support my ongoing work, go to my Patreon site - www.patreon.com/sadler If you'd like to make a direct contribution, you can do so here - www.paypal.me/ReasonIO - or at BuyMeACoffee - www.buymeacoffee.com/A4quYdWoM You can find over 3500 philosophy videos in my main YouTube channel - www.youtube.com/user/gbisadler Purchase Thomas Aquinas' Summa Theologiae - amzn.to/2ITcKYQ

Thomas Aquinas Summa Theologiae - Mutual Indwelling As An Effect Of Love - Sadler's Lectures

2026-01-1813:14

This lecture discusses key ideas from the medieval Christian philosopher and theologian Thomas Aquinas' Summa Theologiae, 1st part of the 2nd part, question 28 "The Effects Of Love", and examines his discussions in article 2, which centers on the question whether mutual indwelling (mutua inhaesio) is an effect of love. Thomas considers several arguments that seem to rule against this being the case, then distinguishes between how it can be understood with respect to the apprehensive and appetitive powers, and how the latter works with love of concupiscence and love of friendship.

Motive, Moral Discourse, and Conflict in George R.R. Martin's Song of Ice and Fire

2026-01-1520:46

This is the recording of my presentation at the Mid-Atlantic Popular & American Culture Association 2011 conference, applying Aristotelian moral theory to reading George R.R. Martin's series Song of Ice and Fire. In it, I argue that Martin articulates a essentially neo-Aristotelian view of human nature, characters, development, ethos and moral qualities, referencing selected events, characters, dialogues, monologues, and decisions from the narrative, I focus upon four aspects of a neo-Aristotelian view of moral life, character, and discourse, namely: community as sharing (koinonia) but also locus of conflict over moral qualities and judgments motivational interplays between interests, desires, loyalties, and common goods ethos reflected in both individual characters and houses characters’ choice and development as matters of better or worse practical reasoning towards and about the variety of human goods.
