Hieroglyphs followed soon after, while early alphabets emerged millennia later. For years, this has served as the neat starting point of recorded human thought. A new body of research suggests that the impulse to register experiences may actually be much older.The evidence comes from artefacts found mostly in a cave system in southern Germany. Researchers examining objects such as mammoth-tusk fragments and bones noticed recurring sequences of notches, crosses and dots carved into their surfaces, some of which are roughly 45,000 years old. Their repetition and structure suggest patterned meaning, what linguists call a “proto-system” of notation — not quite language with formalised grammar, but something closer to a hunter-gatherer’s mnemonic aid. It was utilitarian but it also doubled up as a private archive.AdvertisementThe distance between a Sumerian tablet and these patterned sequences is vast. Yet the instinct behind them may not be too dissimilar: To record the passage of time, to preserve the granular textures of experience against the erasures of memory, to be alive to the anxieties of ephemerality. It suggests that the personal has always been the counterpoint to grand history, a small act of defiance against forgetting. Seen in this light, the contemporary emphasis on journaling is a return to an older premise of self-discovery, to what the 20th century British writer Aldous Huxley put as: “Every man’s memory is his private literature”.
