Rereading Is Not Repetition

Today I'm Rereading an Old Book

Today is World Book Day.

I didn't start a new book today. I pulled an old one off the shelf — one that had been sitting there unread for a long time — and started leafing through it again.

As I turned the pages, I found it interesting, and I wanted to write something about rereading.

I Used to Overestimate Myself

For a long time, I held an illusion: once I'd genuinely finished a book — even if I couldn't remember every page — I had at least broadly digested and absorbed it. The rest would naturally settle over time.

Later, I came to feel more and more that this kind of judgment was usually too optimistic.

Many times, we actually overestimate how much a single reading truly allows us to absorb. When we finish, we think we understand — we may have even underlined passages and written a few notes — and that makes it even easier to feel a sense of completion. But when we look back after some time, we find that what actually stayed with us was perhaps only a small fraction.

This isn't because we weren't attentive enough. The more honest explanation is: the first time you read a book, you can only bring the you of that moment into it. Your experiences at the time, what you were thinking about, the judgments you'd already formed — all of this determines what you're able to see, and also what you're temporarily unable to see.

Having read something, and having absorbed it, are not the same thing. Being moved by a sentence, and truly understanding it, are not the same thing either.

Opening It Again After a Few Years

Sometimes, two or three years later, I'll pull a book I've read before off the shelf and flip through it casually.

The experience is interesting. Sometimes it feels unfamiliar — a book I've clearly read before, yet certain pages seem like I'm seeing them for the first time. Sometimes I'll come across annotations I left before and suddenly find them amusing. Those few words may not have been particularly well-written, but they belong very specifically to the me of that time. Looking at them creates a strange feeling — not so much like looking at an old book, but like running into a version of myself from some past moment.

Sometimes this prompts me to make a decision: I want to reread this book soon.

Once I actually start reading again, the experience is often quite different. Some passages I hadn't noticed at all before will now make me stop. Some sections that once excited me greatly now feel less striking on re-reading. And some sentences that I first thought "that's beautifully written" — it's only on the second reading that I begin to really understand what the author was saying.

The book is the same book. But the person reading it is no longer the same person.

Rereading Looks Like Repetition, But It Isn't

On the surface, rereading really does look like repetition. You open the same book again, you read those same words you've already read. If you look at it only from this angle, a question easily arises: isn't this a waste of time?

I have this feeling myself sometimes. I'm reading along, and suddenly a voice jumps into my head: don't I already know all this? Why am I going through it again?

But the truly important thing about rereading isn't the surface-level act of "reading again." It matters because the person returning to this text has changed. You bring with you everything that has happened in those two or three years — new experiences, new confusions, new judgments — and when you look at the same passages, what happens inside you won't be the same as the first time.

So rereading isn't doing the same thing over again. It's returning to that text from where you stand now, meeting it again, and catching a glimpse of the person who read it back then.

Sometimes you'll find that you've changed. Sometimes you'll find you understand the author more deeply. Sometimes your old annotations will seem naive — and sometimes you'll find that your past self was actually sharper than you are now.

None of this is repetition. All of this is reunion.

Not Every Book Is Worth It

I don't want to overstate this. Not every book deserves a second reading.

Some books perhaps aren't worth reading even once; some you know halfway through that there's no need to finish; and others, having read them once was already enough — going back years later wouldn't yield much that's new.

I've come to feel more and more that an important capacity in reading isn't only knowing what to read, but also knowing what doesn't need to be continued, and what doesn't need to be revisited.

But at the same time, there genuinely are some books worth returning to again and again. Not because they're inherently noble, not because classics should automatically be reread, but because you know that something between you and the book isn't finished yet. When you open it again, you'll find unexpected rewards, and you'll meet again some things that, the first time, you didn't yet have the capacity to truly receive.

As long as books like that exist, rereading deserves to be taken seriously.

If You Want to Do One Small Thing Today

If today happens to be a day when you want to do something for reading, I'd actually be reluctant to suggest you start a new book.

Maybe you could go to your shelf and find a book you once loved, or a book you once underlined and annotated but haven't touched in a long time. Open a few pages and see how you feel now.

You don't need to finish it. You don't need to prove anything. You don't need to rush to judge whether this rereading was worth it.

Just read a small passage again. Meet it again. And meet the person you were when you first read it.

Today I'm rereading a book I used to love. Maybe you can too.
