《古代寓言·自相矛盾》（中英对照）

楚有鬻盾与矛者。誉之曰：“吾盾之坚，物莫能陷也。”又誉其矛曰：“吾矛之利，于物无不陷也。”

或曰：“以子这矛，陷子之盾，何如？”

其人弗能应也。

——《韩非子》

The Man who Sold Spears and Shields

In the state of Chu lived a man who sold shields and spears.

“My shields are strong,” he boasted, “that nothing can pierce them. My spears are so sharp that there is nothing they cannot pierce.”

“What if one of your spears strikes one of your shields?” someone asked him.

The man had no answer to that.
