公孙龙 / Gongsun Long

公孙龙 / Gongsun Long enters the wiki through 《资治通鉴·周纪》64丨 古代“杠精”公孙龙养成记 as a retainer of 平原君 in 赵国. The episode presents him as a famous practitioner of 名辩, especially the arguments associated with “兼白同异,” “白马非马,” and “臧三耳.”

The source’s interest in Gongsun Long is evaluative rather than encyclopedic. He is clearly treated as highly skilled in wording, definitions, and argumentative pressure, but the episode uses 孔川 and 邹衍 to test whether that skill serves truth. In that test, Gongsun Long becomes a case where verbal success can outrun factual and ethical purpose.

His role also extends 战国养士. Pingyuanjun’s household can attract unusual intellectual specialists, not only military aides or diplomatic operators, but the patron still needs a way to distinguish useful reasoning from performance that merely dazzles a court.

Key Claims

• Gongsun Long is presented as Pingyuanjun’s retainer and as a famous debater in the late Warring States intellectual field.
• The episode associates him with “白马非马,” “兼白同异,” “离坚白,” “一同,” and the “臧三耳” exchange.
• His “臧三耳” argument temporarily defeats Kong Chuan in the sense that Kong Chuan cannot answer on the spot.
• Kong Chuan and Zou Yan then recast the issue: an argument can be difficult, clever, and socially impressive while still being false or unhelpful.
• In the episode’s final judgment, Gongsun Long is the negative foil for truth-seeking debate.
