Reading went through the same transition a thousand years ago, Guo says. Until then, reading was done with one person aloud to a group of a half-dozen others. People who could read to themselves silently were rare and remarkable. Monks who’d taken vows of silence were allowed to mumble while doing calligraphy, because mumbling was considered essential to reading.
