OF THREE COMMERCES We must not rivet ourselves so fast to our humours and complexions: our chiefest sufficiency is to know how to apply ourselves to divers employments. ‘Tis to be, but not to live, to keep a man’s self tied and bound by necessity to one only course; those are the bravest souls that have in them the most variety and pliancy. Of this here is an honourable testimony of the elder Cato: “Huic versatile ingenium sic pariter ad omnia fuit, ut natum ad id unum diceres, quodcumque ageret.” [“His parts were so pliable to all uses, that one would say he had been born only to that which he was doing.”--Livy, xxxix. 49.] Had I liberty to set myself forth after my own mode, there is no so graceful fashion to which I would be so fixed as not to be able to disengage myself from it; life is an unequal, irregular and multiform motion. ‘Tis not to be a friend to one’s self, much less a master ‘tis to be a slave, incessantly to be led by the nose by one’s self, and to be so fixed in one’s previous inclinations, that one cannot turn aside nor writhe one’s neck out of the collar. I say this now in this part of my life, wherein I find I cannot easily disengage myself from the importunity of my soul, which cannot ordinarily amuse itself but in things of limited range, nor employ itself otherwise than entirely and with...

Summary
Montaigne reveals his three essential 'commerces' or ways of engaging with life: relationships with people, love affairs with women, and communion with books. He argues against rigidity, advocating instead for flexibility in how we approach different situations and people. While he values deep, authentic friendships, he recognizes the practical need to adapt our communication style to different audiences - speaking simply with servants, intellectually with scholars, warmly with friends. He's learned to be selective about close relationships but warns against becoming so particular that we isolate ourselves from ordinary human connection. His second commerce involves romantic relationships, where he emphasizes the importance of genuine feeling over mere physical attraction or social climbing. His third and most reliable commerce is with books, which provide constant companionship without the complications of human relationships. Montaigne describes his tower study as his sanctuary - a round room where he can see all his books at once, think freely, and retreat from social obligations. He advocates for everyone having such a private space for self-reflection. The chapter ultimately argues for a balanced approach to life: maintaining our authentic selves while adapting to circumstances, seeking meaningful connections while preserving solitude, and finding reliable sources of wisdom and comfort that don't depend on others' moods or availability.
That's what happens. To understand what the author is really doing—and to discuss this chapter with confidence—keep reading.
Terms to Know
Commerce
In Montaigne's usage, this means meaningful exchanges or relationships - not just business dealings, but any way we engage deeply with the world. He identifies three types: with people, with romantic partners, and with books.
Modern Usage:
We still talk about having good 'chemistry' or 'connection' with someone, whether in friendship, romance, or even our relationship with hobbies.
Humours and complexions
16th-century belief that personality came from bodily fluids (blood, phlegm, etc.) that determined your temperament. Montaigne uses this to mean our fixed habits and rigid ways of thinking.
Modern Usage:
Today we might say someone is 'set in their ways' or has a 'fixed mindset' - the idea that some people refuse to adapt or change.
Pliancy
Flexibility and adaptability in how you approach different situations and people. Montaigne sees this as a strength - being able to adjust your communication style without losing your core self.
Modern Usage:
We call this 'emotional intelligence' or 'code-switching' - knowing how to talk to your boss differently than your best friend.
The tower study
Montaigne's private round room in his castle tower, lined with books, where he could think and write in solitude. It represents the importance of having space for self-reflection.
Modern Usage:
Like having a 'man cave,' 'she shed,' or just a corner of your bedroom that's yours alone - somewhere to decompress and think.
Particular friendship
Montaigne's term for deep, authentic friendship based on genuine understanding and mutual respect, as opposed to casual social connections or relationships of convenience.
Modern Usage:
The difference between your 'ride or die' friends and your acquaintances - people who really know you versus people you just hang out with sometimes.

Key Quotes & Analysis
"Life is an unequal, irregular and multiform motion."
Context: Explaining why we need flexibility rather than rigid approaches to living
This captures Montaigne's core insight that life constantly changes and throws us curveballs. If we're too set in our ways, we'll struggle when circumstances shift. Adaptability isn't weakness - it's wisdom.
In Today's Words:
Life is messy and unpredictable, so you've got to roll with it.
"We must not rivet ourselves so fast to our humours and complexions."
Context: Opening argument against being too rigid in our habits and personality
Montaigne warns against becoming so locked into our patterns that we can't adapt to new situations. He's not saying change who you are, but don't let your personality become a prison.
In Today's Words:
Don't get so stuck in your ways that you can't adjust when you need to.
"Those are the bravest souls that have in them the most variety and pliancy."
Context: Praising adaptability as a form of courage
Montaigne reframes flexibility as bravery rather than weakness. It takes courage to step outside your comfort zone and adapt to new people and situations while staying true to yourself.
In Today's Words:
The strongest people are the ones who can handle different situations without losing themselves.

Modern Adaptation
The Three Doors Strategy
Following Arthur's story...
Arthur realizes he's been putting all his emotional eggs in one basket at the university. When his favorite colleague transfers and his department becomes toxic, he's devastated. Following Montaigne's model, he consciously develops three separate 'commerces': meaningful friendships with a few trusted people (including his barista neighbor and a fellow teacher from another school), a passionate side interest in local history walks that energizes him, and a quiet corner in his apartment with books where he can think without interruption. He learns to adjust his communication style - speaking plainly with maintenance staff, academically with administrators, warmly with students - while staying true to his core values. This emotional diversification protects him when any one area goes sideways.
The Road
The road Montaigne walked in 1580, Arthur walks today. The pattern is identical: sustainable happiness requires diversifying emotional investments across relationships, passion, and solitary reflection rather than depending on any single source.
The Map
This chapter provides a blueprint for emotional risk management. Arthur can use it to identify when he's becoming dangerously dependent on one source of fulfillment and consciously build balance.
Amplification
Before reading this, Arthur might have poured everything into his work relationships and felt devastated when they shifted. Now he can NAME emotional over-investment, PREDICT where it leads to burnout, and NAVIGATE it by building a balanced life portfolio.
You now have the context. Time to form your own thoughts.

Critical Thinking Exercise
Design Your Three-Door Life
Draw three doors on paper and label them: People, Passion, and Private Space. Under each door, list what currently fills that area of your life and rate how satisfied you are (1-10). Then identify one specific action you could take this week to strengthen whichever door feels weakest. This isn't about perfection - it's about balance.
Consider:
- •Notice if you're pouring 80% of your energy into one door while neglecting the others
- •Consider how different people require different communication styles, but your core values stay the same
- •Think about what 'private space' means for your situation - it might be time, not physical space
Journaling Prompt
Write about a time when you lost yourself by investing everything in one relationship, job, or goal. What would you do differently now, knowing Montaigne's three-door approach?
