Senior Reading Plan (1): A Book to Re-Read Slowly

On some shelf in your house, there is a book you read thirty or forty years ago. Perhaps it still has pencil underlines, a date on the first page, the name of who you were then. Open it anywhere and read a paragraph: you will see that it says things it did not say before. It did not say them because whoever was reading it then could not hear them yet. Books do not change on the shelf. The one who changes, in the meantime, is you.

That is what the series starting today is about. A reading plan without a syllabus: every so often, a single book, chosen slowly, to be read—or reread—without haste. No homework list or sense of being behind. When we published the ten books to read or reread in retirement here, we spelled it out: maturity is, among other good things, the age of reading better. This series takes that idea seriously, book by book. And there is little doubt about which one deserves to open the door.

An Emperor's Notebook

Around the year 170, the most powerful man on earth sat down at night, in a military camp by the Danube, to write notes that no one was meant to read. Marcus Aurelius, Emperor of Rome and Stoic philosopher, wrote down reminders to himself in Greek: how not to become exasperated, how to accept what does not depend on oneself, how not to overthink things. At the end of some notebooks, he noted the location, like someone dating a letter: among the Quadi, by the Granua river; this, in Carnuntum. He was at war, he had buried children, and his nightly exercise was to put his mind in order in writing.

Those notes were saved by a miracle, and today we call them Meditations, although their ancient title was more honest: things written for oneself. It is one of the most intimate texts in existence, and it brings together three virtues that rarely coincide in a classic: it fits in a pocket, it can be opened to any page, and it improves with every rereading. No one reads it the same way twice, starting with its author, who wrote it precisely to reread himself.

To Reread is Not to Repeat

There is a certain self-consciousness in returning to a book already read, as if it were time taken away from the pile of pending reads. It is wise to lose that feeling, and a Spanish philosopher helps us understand why. Gregorio Luri, who has dedicated an entire book to the art of reading, defines reading as the craft of fitting a text into a context. It sounds like a textbook definition, but it is a key: because the decisive context is not the author's era or the history of the genre. The context is you.

At seventy years old, that context is incomparably richer than at twenty. The same page by Marcus Aurelius about accepting what does not depend on oneself now falls upon half a century of decisions made, losses accepted, and waits that taught more than achievements. The text finds a place to take hold. That is why rereading does not repeat anything: the book works like those measuring devices that self-calibrate, and what it measures, with a precision that is sometimes startling, is how much you have lived between one reading and the next.

What Science Says (and What It Doesn't)

Let us be honest with the evidence, which is the custom here. In 2013, John Dunlosky's team published a monumental report on study techniques in Psychological Science in the Public Interest, and their verdict on rereading was devastating: for exam preparation, rereading notes is one of the least effective techniques that exist, as much as it is one of the most widely used. Compulsive underlining did not fare any better either. What truly works, they concluded, is testing oneself and spacing study into short sessions separated over time.

Does that debunk this series? Rather, it refines it. You are no longer reading to pass anything; that is exactly the advantage. Literary rereading does not aim to memorize facts, it aims for an encounter, and in that, laboratories have little to object to. And there is a detail that almost seems like a twist of fate: the highest-rated technique in that report, spacing, is the scientific description of what a reader does when returning to a classic. The same text visited at twenty, at fifty, and at seventy, with decades in between doing their silent work: spacing in its purest form, only here what is being consolidated is not a syllabus, but a life.

A Book Against Haste

Neuroscientist Maryanne Wolf has spent years studying what happens to the reading brain when everything is read on screens: we gain scanning speed and our deep reading is weakened, that ability to inhabit a text, follow a long line of reasoning, and let it resonate against lived experience. Her book Reader, Come Home has become the reference on this drift. And this spring, something revealing happened: Princeton University chose it as the common reading for all its incoming students of 2026. Its president explained it in one sentence: deep, immersive reading is at the heart of education.

Look at what is inside that. One of the most demanding universities in the world dedicates the first reading of its eighteen-year-old students to defending something they will have to fight to achieve amidst classes, screens, and haste: uninterrupted reading time. That scarce resource that the finest young minds on the planet must learn to protect is, at this stage of your life, an available asset. The afternoon is yours. The silence, too. What on campus is a conquest, in your living room is a door left slightly ajar.

How to Reread the Meditations

Without a solemn method, three helpful habits. First: a little at a time. The Meditations are not meant to be read straight through; they are notes, and they allow themselves to be read as they were written, one or two a day, twenty minutes at most, preferably at the same time. Second: with a pencil. Underline, argue in the margin, write down the date next to what touches you closely; in a few years, those dates will be the best part of the book, because they will turn your copy into another notebook. Third: from anywhere. There is no order to respect; the author himself jumped from one subject to another as the day demanded.

And a route direction for the first afternoon. Open book four and look for the passage on retreats. Marcus Aurelius observes that people dream of retiring to the countryside, the beach, the mountains, and corrects himself: it is in your power to retire into yourself whenever you want. No retreat is more peaceful than that of one's own mind, writes an exhausted man, on a frontier at war, with no beach in sight. Then try the opening of book two, which is pure daily life: when the day begins, tell yourself that you will meet with the ungrateful, the arrogant, and the disloyal. It sounds like pessimism, but it works like insurance: it is the Stoic way of not giving your morning away to the first indignation that passes.

Reading with Someone

There remains the third piece of advice from that list of ten books, which is the most rewarding: conversation doubles the book. A paragraph of Marcus Aurelius discussed with your partner, with a friend, with a reading group, yields twice as much as when read alone, because the other person has lived a different life and the text fits into their context in a different way. Listening to them is reading twice.

That is also the commitment of Thenomba's Senior journey: each of its twelve stages has its own reading plan, prepared with our in-house allies, with classics like this among the recommended ones, and with what no book comes with out of the box: people to discuss it with, live encounters, and a personal notebook to write down what the reading stirs up. Reading slowly and in company: there are few combinations more serious, or more joyful.

The emperor's notebook completed an improbable journey: eighteen centuries, dozens of languages, millions of readers its author never imagined, because he wrote for no one. One of those readers is you. When you open it for the second time, or the third, the book will be new again, exactly to the extent that you are no longer the same. Which is, when you think about it, the most joyful news a shelf can give you.
