Ludwig Wittgenstein is regarded as the most controversial philosopher of the twentieth century since his philosophy indicates zig zag improvisitions, as called Tractarian Wittgenstein and later Wittgenstein, Philosophical Investigations. On the other hand, apart form his writings, it is vital that how many people he influenced, yet his early work was taken up by some of the pioneers of analytical philosophy and his later work lead to another movement, that of ordinary language. Meanwhile, he is also considered as a key to bridge the gap between analytical and continental philosophy. Thus, all these points indicate the importance of dealing with Wittgensteinian philosophy of language. However, it is vital to pay careful attention to which Wittgenstein is being taken into consideration. In fact, the author deals with the metaphysical status of "language game" in later Wittgensteinian philosophy of language whether "conceptual revolution" or not. In this book, the author's main aim is firstly to clarify the role of metaphysics in early and later Wittgenstein's philosophy of language.
