Self-Help from the Middle Ages by Peter Jones What the Seven Deadly Sins Can Teach Us about Living
What's it about?
Self-Help from the Middle Ages (2026) explores how medieval ideas about sin, confession, and moral struggle can illuminate modern problems such as anxiety, envy, burnout, and self-control. Using the seven deadly sins as a framework, it connects historical beliefs about the mind and soul with practical reflections on temptation, guilt, desire, and change.
Most of us think of the seven deadly sins as relics of medieval religion – maybe a little dramatic, maybe even a little comic. But for medieval thinkers, they were something far more practical: a map of the mind. Pride, envy, anger, sloth, avarice, gluttony, and lust were ways of naming the habits that pull you away from other people, from reality, and from yourself. What makes this old system surprisingly useful is that it doesn’t treat human weakness as strange or shameful.
It assumes that everyone struggles with thoughts and feelings that aren’t always constructive. The goal is to notice what’s happening inside you before it starts making your choices for you. In this lesson, you’ll learn how medieval ideas about the seven deadly sins can help you understand ego, comparison, rage, despair, money, appetite, and desire with more honesty and compassion. Let’s begin with the sin medieval thinkers feared most: pride.
Pride can sound like one of the healthier emotions. You can be proud of work well done, proud of someone you love, proud of a part of yourself you once hid or doubted. Medieval thinkers were interested in a more dangerous version. They saw pride, or superbia in Latin, as the moment self-belief drifts away from reality and starts treating other people as obstacles, audiences, or tools.
The danger begins with a mistaken idea of your own importance. You decide you’re a little more gifted, a little more exempt, a little less in need of help than everyone around you. From there, the pattern hardens. Rules start to feel optional. Advice sounds insulting. Criticism becomes something to defeat rather than understand.
At its worst, pride makes you stop seeing other people clearly, because your attention is fixed on protecting a flattering picture of yourself. That’s why medieval artists returned to Lucifer so often. Before his fall, he could appear radiant, intelligent, and powerful – surrounded by signs of rank that made him seem higher than those around him. He was beautiful, and that made his pride seductive before its damage was visible. Beauty, ability, and ambition can become spoiled when they turn inward and refuse responsibility. Lucifer’s failure was choosing display over goodness, status over service, and separation over shared life.
This makes pride easier to recognize in ordinary life. It can show up as the need to seem special, the habit of bending rules for your own comfort, the urge to dominate a conversation, or the refusal to cooperate because dependence feels beneath you. Medieval writers weren’t asking you to hate yourself. After all, healthy pride can be an honest pleasure! The problem begins when your image of yourself grows larger than your actual life. So, what’s the remedy?
It’s accurate self-knowledge: see what you have, see what you lack, and let other people matter. Now let’s look at envy, where the gaze turns outward and becomes just as dangerous. Comparison can begin innocently enough. You notice another person’s success, measure it against your own life, and feel a pinch of unfairness.
Medieval envy, or invidia, begins there but moves in a harsher direction. It doesn’t merely want the same good thing; it wants the other person’s good to be reduced, spoiled, or taken away. That’s why medieval artists often pictured envy as a sickness affecting your ability to see and speak. In Giotto’s image of Invidia in the Arena Chapel, the figure’s damaged eyes, animal features, clutching hand, and serpent-like imagery turn envy into a whole-body disorder.
The idea is clear: envy changes how you look at others. Their happiness starts to feel like an accusation. Their gifts become threats. Their flaws become strangely satisfying. The story of Cain gave medieval writers a way to explore how envy can grow from a real grievance. Cain’s work was harder, his offering was less impressive, and his brother Abel received the approval he wanted.
Resentment often begins with a wound that feels reasonable. But the danger comes when pain stops asking for fairness and starts hungering for destruction. In Cain’s case, that hunger ended with Abel’s murder: he tried to escape comparison by eliminating the brother whose acceptance he couldn’t bear. Judas represents a colder version. His envy wasn’t an instant flare of hurt, but a planned attempt to smother another person’s greatness. In that form, envy becomes secrecy, betrayal, and the wish to make someone else smaller so you can feel bigger.
So, what can you do to avoid this trap? One useful move is to reshape your attention. If envy makes you study another person intensely, you can redirect that focus toward admiration, compassion, and honest self-improvement. Envy narrows the heart, but positive attention can reopen it. In the next section, we turn to anger, where the feeling of being wronged becomes even hotter. Anger has a strange moral glamour.
When you feel it, the world can seem suddenly obvious: someone has crossed a line, something has gone wrong, and your body is ready to answer. Medieval thinkers called this anger ira, and they took it seriously because it can point toward justice while also pulling reason out of your hands. Consider that double nature. Some anger was seen as legitimate, especially when it appeared quickly in response to real harm and faded once the wrong had been addressed.
No figure captures this better than Judith. Her city was under siege, its people were being starved of water, and the invading general Holofernes was using cruelty as strategy. Judith’s rage was therefore treated as morally defensible, even when medieval artists disagreed about how furious she should look while acting on it. Some images show her almost calm, others show violent intensity. Together, they ask a difficult question: How much anger can justice safely hold? The danger comes when anger stops serving repair and begins feeding itself.
Henry II’s conflict with Thomas Becket shows this darker pattern. Their relationship moved from friendship into political hostility, then into rage, threat, exile, and murder. It’s not that Henry simply had a temper. His anger grew inside a situation shaped by control, status, wounded pride, and frustration with resistance. Once fury took command, it turned a dispute into a catastrophe. The lesson here isn’t that you should suppress anger at all costs.
Anger can help you notice injury, cowardice, or injustice. But it needs limits, timing, and a destination. Medieval advice points toward strengthening the heart with compassion, because rage without care eventually empties you out. The test is whether anger helps you protect what matters, or whether it keeps you searching for another target. Next up? Sloth, where the struggle isn’t too much feeling but too little.
Sloth is easy to misunderstand. The modern picture is usually laziness: staying still, avoiding effort, putting things off. Medieval thinkers meant something heavier by acedia. They saw it as a collapse of attachment, a state where the world still asks things of you, but your heart no longer answers with energy, pleasure, or trust.
That makes sloth unusually painful, because it can feel less like a choice than an invasion. Pride can be performed, envy can be aimed, and anger can be released. Acedia often arrives as numbness. You may know what matters, remember what used to move you, and still feel unable to act. Medieval writers described this condition through fear, bitterness, withdrawal, and despair Рa pattern close enough to modern depression that it still feels recognizable. Elisabeth of Sch̦nau exemplifies one side of this experience.
Her religious life had been built around devotion, prayer, and song, but acedia left her feeling cut off from the very love that once sustained her. Dante offers another version. His despair grew through grief, exile, and disconnection from Florence, until the life that had once given him purpose seemed almost unreachable. In both cases, sloth attacked people through what they cared about most. Love didn’t disappear; it became too heavy to carry. The easiest escape is also the wrong one: distraction.
Dante warned that when you’re restless and hollowed out, attractive diversions can seem like rescue. But all they really do is pull you further from yourself. The safer path is to find something steadier than your mood: a person, practice, place, memory, or calling that reminds you who you are beneath the exhaustion. Sloth can’t be beaten by scolding yourself into productivity.
It loosens when you rebuild contact with meaning, one honest movement at a time. Now let’s turn to avarice, where desire turns away from people and fixes itself on things. We often want things because they seem to promise a better version of ourselves.
A jacket, a room, a phone, a house, a bank balance – each can shift from something you use to proof that your life has become impressive. Medieval thinkers called this avarice, and they understood it as excessive love directed toward material things, especially when the desire to acquire or keep them begins to take charge of you. That fear made sense in medieval Europe, a period when trade expanded, banking developed, luxury goods circulated more widely, and money became a stronger social force. Writers such as Francis of Assisi responded with suspicion toward ownership itself.
For him, possessions could subsume a person, making someone spend so much energy on surfaces that the self underneath grew weaker. But the lesson isn’t simply anti-materialist. After the Black Death reshaped wages, housing, and access to goods, people lower down the social ladder could own things that once belonged only to elites. Jaume, a freed man in Valencia, had fine clothing and household objects, and his case complicates any easy judgment. A beautifully made doublet might be vanity for one person but dignity for another – especially in a society quick to judge status by appearance. So avarice isn’t cured by despising all objects.
The better question is whether a possession enlarges your life or starts replacing it. Medieval thinking makes room for material beauty when you learn to see craft, memory, care, and human effort in an object rather than treating it as a trophy. Desire becomes healthier when things connect you to meaning instead of trapping you in craving. Next up is gluttony, where appetite turns from pleasure into fixation.
Gluttony sounds like the simplest sin: too much food, too fast, with too little restraint. Medieval thinkers made it far more interesting. For Pope Gregory, gluttony could mean excess, eating before real hunger, intense craving, devotion to luxurious food, or a fussy demand that everything be exactly right. That means a person could fall into gluttony through overeating – but also through connoisseurship, purity rules, or anxious refusal.
The common denominator here is fixation; food stops supporting life and starts occupying the center of the mind. Thomas Aquinas sharpened this idea. His concern was not the menu itself, but the moment appetite outruns reason. You might eat too much, eat with frantic urgency, insist on rare delicacies, or become so delicate in your preferences that ordinary nourishment feels unacceptable. In each case, food gains too much power over thought. A meal should answer hunger and help you return to what matters.
When taste becomes an organizing principle, you’re no longer simply enjoying food. You’re being managed by it. The same logic applies to drink. Medieval writers knew alcohol could help people loosen self-consciousness and confront hidden parts of themselves, but they also knew it could become escape. The line is crossed when drinking hides you from reality rather than helping you face it. The question is whether pleasure leaves you clearer about yourself, or more lost.
That’s why Francis of Assisi is such a useful guide. His rule wasn’t to despise food, but to avoid fussing over it. Eat what’s offered, accept limits, and let food serve conversation, care, and shared life. Gluttony isn’t defeated by body-shame or strict denial.
It eases when appetite takes its proper place, leaving you free to enjoy pleasure without obeying it. In the final section, let’s look at lust, where desire turns toward bodies and imagination. Lust, or luxuria, sits unusually close to love.
Medieval writers treated it as the mildest of the seven sins because it begins with a force that can pull you toward another person, toward bodies, and even toward wonder. The danger comes when that pull narrows your world until a living person becomes an image you want to possess. For Bernard of Clairvaux, desire could move in more than one direction. It could sink into fixation on bodies, where pleasure turns shallow and self-enclosed.
Yet it could also rise toward devotion, service, and full attention to another life. That makes lust morally unstable. The same physical energy that can reduce someone to a surface can also become part of love, care, and even spiritual longing. The task is to steer desire outward, beyond your private appetite. Bosch’s Garden of Earthly Delights captures this idea wonderfully. Across the painting, people tuck themselves into shells, fruit, spheres, and cramped enclosures.
At first, the scene looks like freedom, play, and erotic abundance. Then the repeated enclosures begin to feel troubling. Desire is creating private little worlds, cutting people away from time, consequence, and genuine connection. That’s the deeper problem with luxuria. It holds you in the present moment and asks you to forget that the person you desire has a history, a future, and an inner life beyond what attracts you right now. Love does the opposite.
It lets another person remain whole, changing, vulnerable, and real. Lust says stay inside the image; love asks you to meet the person in front of you. The final lesson here is simple: desire doesn’t need to be crushed. It needs to be opened until it leads you out of fantasy and back into shared life. The main takeaway of this lesson to Self-Help from the Middle Ages by Peter Jones is that human flaws aren’t signs of failure, but signals worth reflecting on.
Pride, envy, anger, sloth, avarice, gluttony, and lust each begin with ordinary impulses: self-belief, comparison, justice, exhaustion, desire, appetite, and attraction. They only become harmful when they narrow your attention, cut you off from others, or make you mistake fantasy for truth. The wiser response isn’t denial or self-punishment, but honest self-knowledge. When you learn to recognize these patterns with compassion, you can live with your weaknesses without letting them lead your life.
