means A mind or situation imagined as starting with nothing written on it yet — no fixed traits, history, or bias to work around.

from Translates the Latin 'tabula rasa' — an actual wax writing tablet smoothed over so it could be reused. The philosophical idea became famous through 17th-century empiricists, especially Locke, who argued the newborn mind holds no innate ideas, only experience waiting to be inscribed. Later science pushed back hard on the metaphor — genes and temperament turn out to leave their own faint grooves in the wax before anyone picks up the stylus.
