Wittgenstein thought that it was incomprehensible to imagine an individual creating their own private language. 他认为设想一个个体创造他们自己的私人语言是不可理解的。
If a private language is not possible then the rug has been pulled from under the feet of modern philosophy's Cartesian foundations. 如果私人语言是不可能的，那么就会破坏现代哲学的笛卡尔基础。
