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.

no, not John’s, but his own

你知道B肯定是对的
这位作者就是指"he"，言外之意这句话有两个对象，he和John
那么 he指出就不会有矛盾了，首先John肯定没有took the stick
其实我要是做第一反应也是那么选

这个句子在addressing "he"这个人。不清楚的只在于他拿了谁的棍子。。。
