Seven books I keep close because I love them

There's a peculiar physics to the books we keep close—a physics that has nothing to do with atoms and everything to do with the strange architecture of human memory. Mark Dominus's post (https://blog.plover.com/2026/08/02/) taps into a phenomenon that cognitive scientists are only beginning to map: our brains offload vast amounts of processing onto external objects, and books are among the most powerful external processors ever invented. Think about it. A well-loved book is not a static object. It's a palimpsest of every reading you've ever given it—margin notes, dog-eared pages, the faint coffee stain from a particular morning. When you pick it up, you're not just retrieving information; you're re-entering a state of mind. This is remarkably similar to how quantum systems maintain coherence: the book is your entanglement partner, and each reading is a measurement that collapses your past self into a new configuration. The "weird" part is that this attachment is deeply non-functional. You could find all seven books online in seconds. You could re-download them, re-sync them, carry them all on a device weighing less than one of those physical volumes. Yet you don't. There's something about the physicality—the weight, the smell, the specific typography—that digital reproduction simply cannot replicate. It's as if the information itself is entangled with its substrate, and separating them destroys the meaning. Dominus's list is, in a sense, a map of a mind. The seven books he keeps close are not necessarily the "best" books, or the most important, or even the ones he'd recommend to a stranger. They are the ones that have become part of his cognitive architecture—external memory drives that, when held, restore specific neural states. This is the wild part: we are not just readers of books; we are cyborgs, and these volumes are our prosthetic memories. So the next time you keep a book close, consider what you're really doing. You're not storing information. You're maintaining a coherent quantum state—a fragile entanglement between your past and present selves, held together by paper, ink, and love.
