Abstract

According to recent researches on middle- or later-Wittgenstein, it has sometimes been claimed that he showed that self-knowledge (at least, one as having a form of propositional attitude) concerning phenomenal experiences was impossible. But his original arguments seem to be unsuccessful. In this paper, I will present another case for the above conclusion, employing some ideas from early-Wittgenstein. If the argument is correct, then it will follow that one cannot know that she herself is in pain, and moreover, that the epistemological problem concerning why self-knowledge about phenomenal experiences has some kind of authority cannot arise.
