"Talking about" and "dealing with" are parallel strategies employed by Wittgenstein as he walks through the constitutive remarks of the Philosophical Investigations. He will talk about language-games from the position of a language-game that offers a view to others. He will also deal with problems that emerge in the practices of a language-game, particularly the language-game called philosophy. It is an outside/inside distinction that indicates where Wittgenstein sees himself in relation to the language-game(s) he is considering. We can see how criticism and metaphor may emerge from between language-games as well as within a language-game.
