Passage 3 On Etiquette by W illiam Hazlitt
Etiquette to society is what apparel to the individual.Without apparel men would go in shameful nudity which would surely lead to the corruption of morals，and without etiquette society would be in a pitiable state，and necessary intercourse between itsmemberswould be interfered with by needless offenses and troubles.
If society were a train，the etiquette would be the rails along which only the trains could rumble forth.If society were a stage coach，the etiquette would be the wheels and axis on which only the coach could roll forward.
The lack of proprieties could make themost intimate friends turn to be themost decided enemies，and friendly or allied countries declare war against each other.We can find many examples in the history ofmankind.
Therefore Iadvise you to stand on ceremony before anyone else，and，to take pains not to do anything against etiquette lest you give offences ormake enemies.

论礼仪(https://www.daowen.com)
——威廉·赫斯利特
礼仪之于社会犹如衣着之于个人。人若不穿衣服，就会一丝不挂，令人耻笑，必然导致道德败坏。如果社会没有礼仪就会陷入可悲的境地，而社会成员之间的所必需的交往就会被无谓的冲突和纠纷干扰。
假如社会是一列火车，礼仪就好比轨道，火车只能沿着轨道隆隆前进。假如社会是一辆贵宾马车，礼仪就是车轮和轴心，马车只能靠它才能滚滚前行。
缺了礼节，最亲密的朋友会变成死敌，友好或结盟的国家会兵戎相见。我们可以从人类历史上找到很多这样的例子。
因此，我劝你对任何人都要讲究礼仪，并且尽力不做违背礼仪的事情，以免冒犯他人或者树敌。
