西试思维认为人是sinner,以法和system as the basis of the society.
中试思维认为人本善, 以道德观 as the basis of the society.
二子 is saying as long as I don't violate law or rules, it's my freedom. if the majority people don't like it, we can create a law or rule such as 每次上电车的时候都有广播,要大家关闭手机. it's very specific, not based on "you think I think". 东西manner 是仁者见仁,智者见智,for example, westerners don't like the sound when we drink soup, but they have no problem with sucking their dirty fingers which I find disgusting. there is another word "taboo".
