However, a proposition, like, "A says she knows it is raining, but A says at the same time that she does not believe that it is raining", is about a state of mind and a question regarding its logic is about what may be generalized. I can't see where analytical philosophy may be of help here, as the proposition would be just meaningless. (Let's say, Wittgenstein I wouldn't be of help, Wittgenstein II maybe. But I wouldn't consider the latter as analytical in the strict sense.)
