The Blue and Brown Books

This publication includes lectures and notes by Ludwig Wittgenstein, which served as preliminary materials for his "Philosophical Investigations", one of the most famous philosophical works of the 20th century. The "Blue Book" is a summary of lectures delivered by Wittgenstein to students at Cambridge in 1933-1934. The "Brown Book" was dictated by Wittgenstein to his Cambridge students. It is here that Wittgenstein attempts to describe in popular form the key themes of his later philosophy, as well as providing a detailed list and analysis of language games (later he will not elaborate on their details as thoroughly). The "Blue and Brown Books", classic texts of late Wittgenstein, offer an opportunity to immerse oneself in an unusual philosophical "stream of consciousness" and learn firsthand about the reflections of a person who fundamentally changed the course of modern philosophy.
