If the Lips are Gone, the Teeth will be Cold

INTRODUCTION
English translation pending.
CORE DEFINITION
The phrase comes from the Zuo Commentary, in the account of Duke Xian of Jin borrowing passage through Yu in order to destroy Guo; after Guo fell, Jin turned and destroyed Yu as well. The image of lips and teeth expresses structural interdependence: the weaker party absorbs the first shock, so its collapse exposes the stronger one. The claim is not about sentiment but about position, and it implies that defending a buffer is a form of self-defense.
SCAFFOLDING EFFECT
Reduce cognitive load
- Map the buffer: identify who absorbs the first impact before it reaches your position. - Trace the transmission: work out the path by which their failure would reach you. - Defend early: support the buffer before the shock arrives rather than after it falls.
Anchor fast decisions
When one party stands between a threat and another, the front party absorbs the initial cost. Removing it does not remove the threat; it only shortens the distance to the party behind. Aid to the buffer therefore buys time and reduces the eventual impact on the protected party, which is why such support is rational even when it looks altruistic.
