But does the fact that Neuer was playing football mean that the only ethical rule is "win at all costs"?

难道诺伊尔正在进行足球比赛就表示唯一的道德规范是“不惜一切代价赢得比赛”吗？

But in fact the doctrine was concerned the specific ethical code and should not be generalized into some class' rule.

其实，“礼不下庶人”是讲具体的礼仪规定的，不能抽象成阶级原则；无论是从理论上，还是从事实上看， 庶人都是有“礼”的。
