Turning the Spear
Updated 2026-08-11
INTRODUCTION
English translation pending.
CORE DEFINITION
Turning the spear takes its name from the Chinese parable of a seller who claimed his spear could pierce anything and his shield could resist anything, then was asked what would happen if the two met. The core proposition is that an opponent's own commitments, criteria, or resources can be redirected to defeat their position. The key qualification is grounding: the reversal must rest on what the opponent actually asserted or did, because a reversal built on a misreading collapses the moment it is examined.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use standard reversal: apply the opponent's own criterion to their case and show it fails. - Use resource redirect: repurpose the force aimed at you as the instrument of your reply. - Use priority flip: show that their stated priority, honestly applied, favors your position.
Anchor fast decisions
Any position strong enough to attack usually carries commitments that constrain it. When you accept the opponent's criterion instead of disputing it, you remove their ability to reject your conclusion without rejecting themselves. The argument then costs them consistency rather than requiring new evidence from you, which shifts the burden of proof. The same logic applies to resources: a weapon aimed in one direction can be redirected if you control its line of travel. Reversal works by converting the opponent's strength into the constraint that defeats them.
