《韩非子·内储说上七术》
孔子说： 追逐野兽的人既快乐又不受罚，而救火的人既受苦又不得赏，这便是没人救火的原因。 哀公说： 说得对。 
仲尼曰： 夫逐兽者乐而无罚，救火者苦而无赏，此火之所以无救也。 哀公曰： 善。 
Confucius said: "Those who chase animals experience both pleasure and the avoidance of punishment, while those who put out the fire endure hardship without gaining any reward. That is why no one is putting out the fire." Duke Ai said: "That is correct."
