比如这篇文章：The common belief of some linguists that each language is a perfect vehicle for the thoughts of the nation speaking it is in some ways the exact counterpart of the conviction of the Manchester school of economics that supply and demand will regulate everything for the best. Just as economists were blind to the numerous cases in which the law of supply and demand left actual wants unsatisfied, so also many linguists are deaf to those instances in which the very nature of a language calls forth misunderstandings in everyday conversation, and in which, consequently, a word has to be modified or defined in order to present the idea intended by the speaker: "He took his stick-no, not John's, but his own." No language is perfect, and if we admit this truth, we must also admit that it is not unreasonable to investigate the relative merits of different languages or of different details in languages.

有一道题中说作者在这篇文章当中使用了generalization，想请教各位，这篇文章的generalization在哪？

附带一个我搜到的关于generalization的定义：

Generalization is a process by which one makes a sweeping statement that is meant to extend to all entities. One could also describe generalization as the drawing of overall conclusions about a group of people or events. Many find this term easier to understand after examining some examples, such as the following.

One example of generalization would be to say that dogs hate cats. In general, most know that this is true. However, here, one can see the drawback of generalizing. There are certainly exceptions to this rule. Some dogs do not hate cats.

Another example of generalization would be to say that girls like to shop. Certainly, many girls do like to shop. However, in generalizing, the ones who do not are not mentioned because the person doing the generalizing does not see them as the norm.
