In 1492, a German monk named Johannes Trithemius sat down to write a passionate defense of an ancient practice he believed was dying: the hand-copying of manuscripts. A new technology had arrived that could reproduce a text in hours rather than months, that put books within reach of ordinary people, that threatened to make the monk's most sacred work unnecessary. Trithemius believed this would be a catastrophe, and he took to the page to say so.

He called his treatise In Praise of Scribes. He had it printed on a printing press.

But what makes Trithemius worth dwelling on is not the irony. It is how right he was about the wrong things, and how completely blind he was to the thing they were losing that actually mattered.

His predictions about the printing press were largely accurate. Paper was less durable than parchment. Printed texts flooded the market with errors. The Church's authority over knowledge was destabilized. Trithemius looked at the printing press and predicted disruption and a loss of quality. Technically, he was right on both counts.

But the thing he was actually mourning, without quite being able to name it, was another phenomenon entirely. The monk who spent six months transcribing the Psalms knew those Psalms in a way no reader of a printed edition ever would. The knowledge wasn't just in the book. It was in the body, in the hand, in the thousands of hours of slow meditative repetition. This was a form of understanding that the printing press didn't just replace. It rendered unnecessary. And when it became unnecessary, it quietly ceased to exist.
