Use Strengths Over Faults / 用人取长弃短

Use strengths over faults / 用人取长弃短 is the talent-selection lesson Zhouji 09 draws from 子思 recommending 苟变. The ruler knows Gou Bian can command troops but hesitates because Gou Bian once took two eggs while collecting taxes.

Zisi’s analogy is practical: a carpenter uses usable timber by taking the strong part and discarding the weak part. In a wartime state, losing a capable commander over a small blemish can harm the polity more than the original fault did.

The concept does not say misconduct never matters. Its source-scoped claim is narrower: rulers need proportion, role-fit, and context when judging flawed talent, especially when state survival depends on scarce military ability.

Key Claims

• Talent evaluation should separate role-critical strengths from lesser defects.
• Small past faults can become strategically expensive if they cause leaders to waste scarce capability.
• The lesson is bounded by context: wartime urgency changes the tradeoff but does not erase judgment.
• The episode treats Zisi’s argument as “资治” material because it links moral evaluation to governing consequences.
