Philosophical Investigations
Published two years after his death, this is Ludwig Wittgenstein's second great work, and it overturns much of his own earlier thinking. Written as a series of short, numbered remarks rather than a continuous argument, it explores how language actually works. Wittgenstein introduces the idea of language games, the notion that words get their meaning from the activities and rules in which we use them, not from inner mental pictures or rigid definitions. It is dense and demanding, more a set of puzzles than a textbook. Reid Hoffman, who studied philosophy, has named it a book that can shift the way you think, and says it influenced how he thought about LinkedIn.
