 Whereas others can learn of my pain, for example, I simply "have" my own pain; it follows that one does not "know" of one's own pain, one simply "has" a pain.For Wittgenstein, this is a grammatical point, part of the way in which the language-game involving the word "pain" is played.Although Wittgenstein certainly argues that the notion of private language is incoherent, because of the way in which the text is presented the exact nature of the argument is disputed.
