Later Wittgenstein

One strain of language analysis continued Wittgenstein's later philosophy, from the Philosophical Investigations (1953), which differed dramatically from his early work of the Tractatus. The criticisms of Frank P. Ramsey on color and logical form in the Tractatus led to some of Wittgenstein's first doubts with regard to his early philosophy. Philosophers refer to them like two different philosophers: "early Wittgenstein" and "later Wittgenstein". In his later philosophy, Wittgenstein develops the concept of a " language-game " and, rather than his prior picture theory of meaning, advocates a theory of meaning as use. It also contains the private language argument and the notion of family resemblance.
