Activity is central to Wittgenstein's account of meaning, whether or not that account is a theory, description, therapy or, simply, an investigation. This chapter focuses on the activity: learning. There is disagreement about what can be provided philosophically in the absence of explanation. That disagreement marks the battle lines between the 'New Wittgensteinian' readings and the standard reading. The chapter explores an idea that challenges the common ground between them. The chapter aims to lay out where the reading stands in relation to the standard readingand to provide sufficient detail from the opening sections of the Investigations to make the reading plausible. The language learner activities are activities that already place them within the practice of language use. Getting clear about the nature of activity in the Investigations is also central to getting a coherent picture of Wittgenstein's attitude to philosophy.
