    Summa Made Simple Ep 46: On Fornication And The“We’re Not Hurting Anyone” Argument

    Click here to become a paying subscriber. “If two consenting adults want to have sex, and they’re not hurting anyone, what’s the problem?” It’s one of the most familiar objections to the traditional Christian view of fornication. Aquinas’s answer takes the argument somewhere unexpected: look at the child. A human child needs far more than food, shelter, and schooling. Children need years of guidance, example, imitation, discipline, protection, and formation. And that raises a question Aquinas thinks we can’t simply ignore: what responsibilities do we have toward the person our actions may bring into existence? In this episode, we follow Aquinas’s argument from fornication to parenting, education, and human development—and discover why he thinks the consequences of sex cannot be measured only by asking whether the two adults involved have harmed each other.

    Summa Made Simple Ep 45: The Argument Against Aquinas Part 2

    An elderly couple can’t have children. Is their sexual relationship therefore sinful? If not, why would contraception be different? Part 2 takes that apparent contradiction seriously and follows Aquinas’s reasoning all the way through. The key turns out not to be whether conception actually happens, but whether we deliberately stand in its way. That distinction—between nature withholding an outcome and the will deliberately preventing it—opens up Aquinas’s entire argument about sex, pleasure, reproduction, and what it means to accept an action for what it actually is. A note from the author: The article discussed in this episode is my own attempt to formulate how St. Thomas Aquinas might respond to some of the modern objections raised against his argument. It is not a text written by Aquinas, but a contemporary reconstruction written in the style of his Summa Theologica. Read the full article along with me via the link in the show notes. I also encourage you to read Humanae Vitae (“On Human Life”) by St. Paul VI, which is also linked in the show notes. Whether or not you agree with its conclusions, it is worth reading the argument in its own words rather than relying on second-hand summaries.

    Summa Made Simple Ep 44: The Argument Against Aquinas Part 1

    If a sexual act cannot result in child-bearing, is it sinful? What happens when you ask AI to produce the strongest possible case against St. Thomas Aquinas? That’s exactly what this episode does. Starting with a modern philosophical critique, we explore the claim that sex has many legitimate purposes, that biology doesn’t create moral obligations, and that Aquinas’s reasoning simply doesn’t hold up. Instead of avoiding these challenges, we follow them to the heart of the debate, where one overlooked distinction reveals why Aquinas’s position is often misunderstood—and why it still provokes such fierce disagreement today. This goes right to the heart of the most common present-day objection that is made against Aquinas’s arguments regarding the morals of sex, as discussed in the last two episodes. In this episode, I use an article that I wrote in the style of St. Thomas Aquinas, with the assistance of a large language model to generate present-day objections, find current sources and get the structure right. NOTES * The source article: Whether sexual acts that cannot result in child-bearing are sinful? * The opinion poll mentioned: Catholic Conformity Poll * Read the relevant article of the Summa here: Summa Theologica.

    Summa Made Simple Ep 43: The Logic Behind Sexual Morality Part 2 - Why Sex Has Boundaries

    Modern debates about sex often begin with personal choice. Aquinas begins somewhere else entirely: with purpose. In this episode, he continues his exploration of lust by asking why different sexual acts belong in different moral categories. His answer isn’t based on emotion or social convention, but on what each act frustrates or damages. Some separate sex from its life-giving purpose. Others place children at a disadvantage. Others violate bonds of family, marriage, or personal dignity. It’s a challenging framework, and many listeners will disagree with parts of it. But before rejecting it, it’s worth understanding the careful reasoning behind it. This episode unpacks that reasoning step by step and shows why Aquinas thought moral distinctions should correspond to real human goods.Read the relevant article of the Summa here: Summa Theologica.

    Summa Made Simple Ep 42: The Logic Behind Sexual Morality Part 1

    Why does Christianity distinguish between different kinds of sexual sins? Is it just tradition, or is there a coherent way of thinking behind it? In this episode, Aquinas argues that morality isn’t built on arbitrary commands. It’s built on understanding the purpose of sex. Before examining six different forms of lust, he explains the principle that makes those distinctions meaningful. Whether or not you agree with his conclusions, his method offers something rare in modern debates: a serious attempt to explain why sexual ethics should follow reason rather than instinct, preference or the crowd.

    Summa Made Simple Ep 41: The Daughters of Lust, Part 3: How Lust Takes Over Your Words

    “Hidden pride? Manifest lust.” - St. Josemaria Escriva. In Part 3, we answer the four challenges raised at the start, and discover something new: lust doesn't just wreck your thinking and your will. It takes over your speech. Saint Thomas walks through four kinds of broken speaking that come from lust. Obscene words spill out because a lustful heart fills the mouth. Scurrilous words rush out without thought — you don't deliberate before speaking, you just let it fall. Wanton words aim for pleasure — sexting and catcalls are lust speaking through you. And foolish words show total blindness — when you can only talk about sex, even while the world burns. You'll also learn the hidden link between pride and lust: pride tells you that you deserve every pleasure, and lust does the work. Finally, you'll see why Saint Thomas loves controversy: objections force you to think harder and find truths you'd miss otherwise. By the end of the series, you'll understand lust as a complete corruption — it breaks how you think, what you want, and even what comes out of your mouth.

    Summa Made Simple Ep 40: The Daughters of Lust Part 2 - Rashness, Thoughtlessness, and Messed Up Priorities

    In the 1997 film, “The Devil’s Advocate”, lawyer John Milton (Al Pacino) is Satan tempting his son Kevin (Keanu Reeves) to join him in his ambition to rule Earth. Milton: Let me give you a little inside information about God. God likes to watch. He's a prankster. Think about it. He gives man instincts. He gives you this extraordinary gift, and then what does He do, I swear for His own amusement, his own private, cosmic gag reel, He sets the rules in opposition. It's the goof of all time. Look but don't touch. Touch, but don't taste. Taste, don't swallow. And while you're jumpin' from one foot to the next, what is he doing? He's laughin' His sick, ****in' ass off. He's a tight-ass. He's a sadist. He's an absentee landlord. Worship that? Never. How does a person get to the stage where they hate God? In this episode we dive into lust being a choice of yourself over God, breeding self-love and hatred of God — you love yourself while hating Him because He stands in your way. From there you start loving everything in this world that feeds the lust , and you stop caring about the next life. Spiritual things start to feel disgusting to you. You'll learn why many people don't believe in God — and it might not be philosophy that broke their faith, but lust. Plus: a 13th century remedy for healing that disgust for spiritual things.

    Summa Made Simple Ep 39: The Daughters of Lust Part 1 - How Lust Blinds the Mind

    Saint Thomas teaches that every capital vice spawns a whole army of smaller sins in its wake — he calls them the “daughters” of that vice. In this three-part series, we’re examining the eight daughters of lust: blindness of mind, thoughtlessness, inconstancy, rashness, self-love, hatred of God, love of this world, and despair of the future. These aren’t random side effects — they flow directly from how lust works on the human person. In Part 1, we establish the core principle: when a lower power (like sex) is strongly moved toward its object, the higher powers (reason and will) become disordered and corrupted. You’ll learn why lust specifically produces blindness of mind — an inability to see what is truly good — and why Christian formation trains the intellect to recognize good and evil as clearly as a herbalist identifies plants in a forest. Understanding the daughters of lust is understanding how vice spreads and why purity of heart matters so deeply. Read the relevant article of the Summa here: Summa Theologica. Part 2 of 2.
