Card #c871IR // #c871Synthesis

A barber rides by on a grey ass, wearing a brass basin on his head against the rain. Quixote sees 'a knight on a dappled grey steed, who has upon his head a helmet of gold.' Sancho sees a man on an ass with something shiny on his head. Quixote declares: 'Well, that is the helmet of Mambrino.' From that instant the basin IS the helmet, and Sancho will call it so for the rest of the book. The narrator's verdict: 'everything he saw he made to fall in with his crazy chivalry and ill-errant notions.'

[Use when]

You need to change what something IS without changing what it is. Rename it in public, get one other person to use the name, and the basin is a helmet now.

[Why it matters]

Naming is framing as a physical act. The object never changes; the word does all the work, and once the name sticks, everyone downstream treats the renamed thing as real. Rebrands, euphemisms, job titles, and political labels all run on Mambrino's helmet.
