The Blue and Brown Books, the classic texts of late Wittgenstein, give us the opportunity to plunge into the unusual philosophical "stream of consciousness" and learn first-hand about the reflections of a person who radically changed the course of modern philosophy." The Blue Book" is a summary of lectures given by Wittgenstein to students in Cambridge in 1933-34. The "Brown Book" was also dictated philosopher to his Cambridge students. It is here that Wittgenstein tries to tell in a popular form about the topics key to his late philosophy, and also gives a detailed list and analysis of language games (in the future he will not dwell on their detail in such detail).
