Meng Debate is invincible. Strict logic is very important. Tan Jiajian believes that Meng, like Mo, has a relatively complete theory of formal logic, but he can generally skillfully use the thinking form of formal logic. All his articles are based on strict logic. Cheng used parallelism and the law of contradiction to discuss who advocated that Meng Du did not lose [2]. The logic used in Meng's argument: (1) Inferred layer by layer, saying that the specific argument was interspersed with deductive induction and counter-capture, and he won: Meng said.

Yue: What if the judge can rule the judge?

Wang Yue: Yes.

Tell you: What are the principles of domestic governance?

Wang Gu talked about him.

Meng Jiaoyou said that he was recognized by Qi Xuanwang and climbed the first step; And department officials and government affairs led to the second step in Qi Xuanwang; The discussion made Qi Xuanwang agree with the political purpose of admonishing the king, although he was willing to express his position.

Confucianism advocates see no evil's indecent assault, don't listen to it, don't speak it, and don't require all manners and manners to conform to etiquette. Meng believes that etiquette should be observed. Take the important aspects of diet and marriage as an example to compare the small details of etiquette. Diet and marriage are more important than manners. Although Confucianism taught Meng to recognize her sister-in-law for helping wolves, Meng recognized her sister-in-law for helping others (building).

Ren Meng Lu Wu said: If you look for food according to etiquette, you will starve to death; If you look for food according to etiquette, you can eat it. You must act according to etiquette and follow the wedding ceremony. Go to the wedding, my wife will definitely go to the wedding. I asked Meng Meng for help: Do you mean that the last inch of wood in Benqi is taller than Cenlou and more important than feathers? You mean the hook is gold and the feather is heavy? Courtesy is lighter than food. Courtesy is lighter than food. If you eat, you can hold your wife beyond the master's wall; Hug your wife and hug her (Meng Gao)

Meng also directly responded to Ren's criticism, citing two examples to indirectly express his views, that is, he should treat people with courtesy, and should not violate the etiquette and do anything that hurts directors at will.
