Developing his debating skills in the legal courts of the state of
Zheng, Deng served as a minor official there. Depicted as taking both sides of his cases, he is said to have argued for the permissibility of contradictory propositions, likely engaging in hair-splitting debates on the interpretation of laws, legal principles and definitions. The Annals of Lu Buwei introduce him as a man who could "argue a right to be wrong and a wrong to be right, [for whom] right and wrong had no fixed standard, and 'yea' and nay' changed every day.... What he wished to win always won, and whom he desired to punish was always punished." Deng attracted many clients seeking legal advice, and apparently charging for cases in articles of clothing, he would eventually have enough to count himself rich. With
Xunzi's book pairing him with
Hui Shi, it is difficult to separate their contributions. An example of his
sophistry: The
Wei River was extremely high. A person from the house of a rich man of Zheng drowned. Someone found the body. The rich man asked to buy it back. The man demanded very much money. The rich man told Deng Xi about it. Deng Xi said, “Calm down. There's certainly no one else he can sell the body to.” The man who found the body was troubled by this and told Deng Xi about it. Deng Xi replied to him by saying, “Calm down. There's certainly nowhere else they can buy the body.” Despite this portrayal, more modern scholars consider that, having taken the time to write his own penal code, Deng may have been a well-intentioned legal reformer opposing what he saw as the suppression of ideas and opinions. Nit-picking over aspects of the law to defy Zichan's attempts to stop the publication of posters, Professors Xing Lu and Zhenbin Sun consider Deng wanted to challenge Confucian Li in favour of litigation and a free exchange, favouring what is termed "big" or communal arguments over petty ones as better resolving issues. ==Legacy==
