A late section of this book discusses a man with “aspect-blindness” as analogous to someone lacking a “musical ear.” A claim in this book about philosophy having methods “like therapies” inspired the therapeutic approach discussed in a book titled for “New” and its author. This book’s opening describes a shopkeeper’s responses to a slip reading “five red apples” while criticizing a quote about naming objects from Augustine’s Confessions. A builder and an assistant communicate with words like “block” and “pillar” in one of this book’s language games. This book rejects private languages with the beetle-in-a-box thought experiment. For 10 points, name this posthumously published book in which Ludwig Wittgenstein reverses many positions from his Tractatus Logico-Philosophicus. ■END■
