What do I know as yet?

The aim of this article is to explore the following complex issues, which appear to be densely interconnected: the connection between the single word meaning and the sentence meaning according to Alston leading over to Wittgenstein’s comments on Moore’s claims about ascertained knowledge. This connects directly to attempts at describing the uses of ich weiß ‘I know’, in particular those by Moore and Wittgenstein, the meaning of the explicit performative, and, finally, to its possible pursuance in an approach to dialogical analysis.
