## Origin

Romans did their everyday writing on wooden tablets coated with wax, scratching letters with the pointed end of a stylus. The other end of the stylus was a flat blade, and drawing it across the wax smoothed everything away. A tabula rasa is that tablet after the blade: scraped clean, ready to be used again. Aristotle had already used the image of an unwritten tablet for the mind at birth, and medieval philosophers working in Latin gave it this name. It became famous in 1689, when John Locke argued that there are no innate ideas and that everything in the mind arrives through experience — a position that has carried the tabula rasa label ever since, and has been argued about continuously since. English uses it for a genuinely fresh start: a new government with no commitments, a rebuilt system with no legacy code, a person arriving somewhere nobody knows them.
