OF THE FORCE OF IMAGINATION “Fortis imaginatio generat casum,” say the schoolmen. [“A strong imagination begets the event itself.”--Axiom. Scholast.] I am one of those who are most sensible of the power of imagination: every one is jostled by it, but some are overthrown by it. It has a very piercing impression upon me; and I make it my business to avoid, wanting force to resist it. I could live by the sole help of healthful and jolly company: the very sight of another’s pain materially pains me, and I often usurp the sensations of another person. A perpetual cough in another tickles my lungs and throat. I more unwillingly visit the sick in whom by love and duty I am interested, than those I care not for, to whom I less look. I take possession of the disease I am concerned at, and take it to myself. I do not at all wonder that fancy should give fevers and sometimes kill such as allow it too much scope, and are too willing to entertain it. Simon Thomas was a great physician of his time: I remember, that happening one day at Toulouse to meet him at a rich old fellow’s house, who was troubled with weak lungs, and discoursing with the patient about the method of his cure, he told him, that one thing which would be very conducive to it, was to give me such occasion to be pleased with his company, that I might come often to...

Summary
Montaigne explores how powerfully our imagination affects our physical reality, sharing stories both personal and historical about the mind's ability to create actual bodily changes. He admits he's particularly susceptible to imagination's force—seeing someone else's pain makes him physically uncomfortable, and he believes our minds can literally reshape our bodies and experiences. Through vivid examples ranging from a man who grew horns after dreaming about them to his own cure for a friend's sexual performance anxiety using a fake magical charm, Montaigne demonstrates that what we believe often becomes our reality. He's especially insightful about sexual dysfunction, arguing that fear of failure often creates the very failure we fear, and that honest communication and mental preparation can break these cycles. The essay reveals how imagination works both ways—it can harm us through negative expectations but also heal us through positive ones. Montaigne suggests that doctors understand this, using elaborate rituals and confident promises to activate their patients' healing imagination. He concludes that our minds and bodies are so interconnected that strong mental states can affect not just ourselves but even others around us. This isn't mystical thinking but practical psychology—understanding how expectation shapes experience gives us tools to work with our minds rather than against them.
That's what happens. To understand what the author is really doing—and to discuss this chapter with confidence—keep reading.
Terms to Know
Imagination's Physical Power
The idea that what we strongly believe or visualize can create actual physical changes in our bodies. Montaigne argues our minds don't just think thoughts—they can make us sick, heal us, or change how our bodies function.
Modern Usage:
We see this in the placebo effect, where fake medicine works if patients believe it will, or how anxiety can cause real stomach problems.
Sympathetic Response
When seeing or hearing about someone else's pain or illness makes you feel those same symptoms in your own body. Montaigne admits he physically feels others' suffering when he witnesses it.
Modern Usage:
This happens when you wince watching someone get hurt in a movie, or when yawning becomes contagious in a room.
Performance Anxiety
The fear of failing at something (especially sexually) that becomes so strong it actually causes the failure you're afraid of. Montaigne explores how worry about sexual performance can create impotence.
Modern Usage:
We see this in everything from stage fright to test anxiety to bedroom problems—fear of failure often creates the very failure we fear.
Psychological Medicine
Using mental techniques, rituals, or beliefs to heal physical problems rather than just drugs or surgery. Montaigne describes how doctors use elaborate ceremonies to activate patients' healing imagination.
Modern Usage:
Modern therapy, meditation apps, and even some medical bedside manner work this way—treating the mind to heal the body.
Self-Fulfilling Prophecy
When believing something will happen actually makes it more likely to happen. Montaigne shows how our expectations shape our reality, for better or worse.
Modern Usage:
If you expect a job interview to go badly, your nervousness might make it go badly—or if you expect to have a good day, you might notice more good things.
Mind-Body Connection
The idea that our mental and emotional states directly affect our physical health and vice versa. Montaigne argues they're so connected that strong feelings can cause real bodily changes.
Modern Usage:
Stress causing headaches, depression affecting appetite, or how positive thinking can boost immune system function.

Key Quotes & Analysis
"A strong imagination begets the event itself."
Context: Montaigne opens the essay with this Latin saying to establish his main point
This sets up the entire essay's argument that our minds don't just observe reality—they actively create it. What we strongly believe or imagine has the power to become real through our actions and bodily responses.
In Today's Words:
If you really believe something will happen, you'll probably make it happen.
"I am one of those who are most sensible of the power of imagination: every one is jostled by it, but some are overthrown by it."
Context: Montaigne admits his own susceptibility to imagination's effects
He's being honest about his own psychological makeup while making a broader point—everyone is affected by imagination, but some people are more sensitive than others. This isn't weakness, just self-awareness.
In Today's Words:
I'm really sensitive to this stuff—we all are to some degree, but it hits some of us harder than others.
"The very sight of another's pain materially pains me, and I often usurp the sensations of another person."
Context: Montaigne describes how he physically feels others' suffering
This shows how imagination works through empathy and observation. He's not just emotionally moved by others' pain—he literally feels it in his body, demonstrating the mind's power over physical sensation.
In Today's Words:
When I see someone hurt, I actually feel it myself—like my brain can't tell the difference between their pain and mine.

When the Mind Creates the Problem
Following Arthur's story...
Arthur's been invited to give a guest lecture at the community college—a huge opportunity that could lead to adjunct work. But the night before, he can't sleep, imagining himself freezing up, forgetting his points, students checking their phones. By morning, his stomach is churning and his hands shake as he reviews his notes. Standing before the class, his worst fears materialize: his voice cracks, he loses his train of thought, and he rushes through material he knows cold. Later, a colleague mentions that the department head specifically requested Arthur because of his reputation as an engaging teacher. Arthur realizes his anxiety created the very disaster he'd feared. The irony stings—he teaches philosophy but couldn't philosophize his way out of his own mental trap.
The Road
The road Montaigne walked in 1580, Arthur walks today. The pattern is identical: our imagination doesn't just predict our reality—it creates it.
The Map
This chapter provides a tool for breaking expectation cycles. Arthur can learn to recognize when his mind is working against him and actively reset his mental script.
Amplification
Before reading this, Arthur might have blamed his 'natural anxiety' or lack of preparation. Now he can NAME the expectation trap, PREDICT when it's happening, and NAVIGATE around it by consciously choosing different mental rehearsals.
You now have the context. Time to form your own thoughts.

Critical Thinking Exercise
Track Your Expectation Cycles
Think of a situation where you regularly expect things to go wrong - maybe giving presentations, having difficult conversations, or trying something new. Write down the specific thoughts that run through your head beforehand, then trace how those thoughts might be creating the very outcomes you fear. Finally, rewrite your mental script with more helpful expectations.
Consider:
- •Notice the physical sensations that come with negative expectations - tension, shallow breathing, racing heart
- •Consider how your expectations might change your behavior in ways that sabotage success
- •Remember that changing your mental script isn't about fake positivity but about realistic confidence
Journaling Prompt
Write about a time when your expectations - positive or negative - seemed to create exactly what you predicted would happen. What does this teach you about the power of your own mind?
