tabula rasa


A blank slate — a mind or a situation with nothing yet written on it.


SIMPLE

New city, new job — a tabula rasa.

CONTEXTUAL

The design team asked for a tabula rasa and got one: no brand guidelines, no existing users, no legacy anything.

COMPLEX

Every incoming administration promises to treat the department as a tabula rasa, and every one of them discovers within a month that the contracts, the pensions and the buildings were all signed for by somebody else.


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.
