Wittgenstein twice thought that he had solved all the problems of philosophy, by explaining how language acquires meaning. The first time, he said that it does so by its relation to the world; the second time, by its relation to itself. To this second suggestion, the concept of ‘games’ is central. In this chapter, I explain and discuss Wittgenstein’s contributions both to the substance and to the ethics of the philosophy of language with ‘games’ focally in view.
