The Cost of a Good Memory, Prospero's Choice, and Remembering Without Collecting
I remember things.
I remember what someone said in a meeting four years ago, the exact phrasing, and the pause before it.
I remember who promised to introduce me to whom and never did.
I remember the tone of an email from 2019.
I remember which song was playing in the taxi on the way to an interview in 2014.
I remember the name of the person who was kind to me on my first day somewhere, and the act of kindness itself.
For a long time I thought of this as an asset, and in most ways it is. Clients notice when you remember the name of their daughter's school, or the thing they said in session two that they'd forgotten they said. Memory is a form of attention, and attention is most of what people want from you.
But there is a cost, and I've been thinking about it a lot lately, partly because I've caught myself carrying a few things that would have been better set down. A good memory is also a good ledger. It keeps score without being asked. And a person who keeps score is a person who is, sooner or later, disappointed.
The man who forgot nothing
In June 1942, on the third page of a Sunday supplement in La Nación, between an essay on Galileo and the week's cinema listings, Jorge Luis Borges published a short story about a young man in Uruguay named Ireneo Funes, who falls from a horse and wakes with a memory that no longer discards anything.
Funes remembers every leaf on every tree he has ever seen. He remembers the shape of every cloud on a given afternoon and can compare it with the veins in a marbled book cover he saw once as a boy. He can reconstruct an entire day, but the reconstruction takes an entire day.
The detail Borges lands on is that Funes cannot think. Thinking, the story tells us, requires forgetting differences, generalizing, abstracting. A dog seen at 3:14 from the side and the same dog seen at 3:15 from the front are, to Funes, two separate animals. He cannot get to "dog." He is, the narrator tells us, almost unable to hold a general idea.
Decades later, neuroscience would give us something that sounds remarkably close to Funes. In 2006, three researchers at UC Irvine published the first documented case of what they called hyperthymesia: a woman, anonymized as AJ, who could recall what she had done on essentially any date since she was fourteen. She later wrote a memoir under her own name, Jill Price, and the word she used most often for her condition was "burden." She described it as a film that never stopped running. What's striking in the original paper is that she was poor at ordinary memorization. She couldn't learn lists. The past came to her whether she wanted it or not, and the present had to fit in around it.
The Harvard memory researcher Daniel Schacter has a name for this. In The Seven Sins of Memory he catalogs the ways memory fails us, and six of the seven are about forgetting or distorting. The seventh, persistence, is the opposite failure: the memory that keeps returning when you would give a great deal for it to leave. Schacter's argument is that persistence is the price of a memory system that works at all. You cannot build a mind that holds on to what matters without it occasionally holding on to what doesn't.
And perhaps that's the uncomfortable thing about a good memory. The same system that allows you to remember what matters can also refuse to let go of what doesn't.
When Ignorance is Bliss
Samuel Beckett plays with this idea in Waiting for Godot. Estragon forgets almost everything, so each day arrives clean. Vladimir remembers. He knows they have waited on this road before, that yesterday went this way, that tomorrow will go the same way. Same tree, same boy with the same message, same non-arrival. Estragon gets to be surprised. Vladimir carries it. I'm not sure Beckett tells us that one is better. Perhaps that's the point.
The phrase everyone reaches for here comes from Thomas Gray, in 1742, looking down at Eton from a distance and watching schoolboys who have no idea what's coming for them:
Where ignorance is bliss, 'Tis folly to be wise.
People quote it as a defense of not knowing. Read in context, it's sadder than that. Gray isn't recommending ignorance. He's watching children who haven't yet been disappointed by anyone, and he knows they will be, and there's nothing to be done about it. The bliss is temporary by definition.
Prospero, in Shakespeare's The Tempest, remembers everything. Betrayal, exile, injustice. But at the end, he chooses not vengeance but forgiveness. He doesn't forget. He chooses.
Memory: What I see in the room
I coach people who carry ledgers. Not everyone, but enough to notice a pattern.
A senior leader at a global technology company, someone I worked with over most of last year, could recount every time a particular peer had undercut her in a meeting, going back to 2022. Dates, rooms, who else was present, what was said. She was not wrong about any of it. But the ledger had become the lens. Every interaction with this person now began with the full history loaded, and she walked into rooms already braced. Her peer, as far as we could tell, had no idea. He had forgotten most of it. Estragon and Vladimir, in the same building.
There's research on what that does to you. In one well-known study, people were asked to recall someone who had wronged them and sit with the memory while their physiology was monitored. Blood pressure and heart rate went up, skin conductance rose, and they reported feeling angry, sad, and less in control. When the same people were asked to imagine empathizing with or forgiving the person, the arousal came back down. A later five-week study found that as people's forgiveness rose, their perceived stress fell, and their mental and physical symptoms followed it down.
None of that makes the ledger wrong. Her peer did do those things. Memory isn't lying. The question is what you do with that accurate record.
Memory Retrieval with Intent
Shakespeare gives us the ultimate choice in The Tempest. Prospero spends twelve years on an island rehearsing his grievances, building the exact conditions to ruin his enemies. But when he finally gets them at his mercy, he chooses not to use the ledger: "The rarer action is in virtue than in vengeance." He retains the memory, but refuses to let it dictate his response.
Orhan Pamuk explored the darker end of this spectrum in The Museum of Innocence, where the protagonist collects 4,213 dated cigarette butts smoked by the woman he loved. It’s a striking image, but it’s a portrait of memory turned inward—building a shrine to the past while life moves on without you.
I don't want to be a passive observer who forgets everything, nor do I want to live in a shrine to past disappointments. I’m working on what I call retrieval with intent.
My memory will naturally retain details. The choice I have is whether I actively go and fetch them. When I feel dissappointed by someone and the mental ledger opens, the test is simple: Is this memory telling me something structural about a pattern, or is it just an old incident seeking airtime? Sometimes the answer is the first. Sometimes it's very clearly the second. A good memory is a gift.
But perhaps the real skill isn't remembering less. It's knowing what deserves to be remembered, what deserves to be learned from, and what can simply be left where it belongs. In the past.
It's a work in progress.
