Wittgenstein on Mind and Language traces the development of a number of central themes in Wittgenstein's philosophy, including his conception of philosophical method, the picture theory of meaning, the limits of language, the application of language to experience, his treatment of private language, and what he called the "flow of life." It also explains how the unpublished manuscripts and typescripts were put together and why they often provide better evidence of the development of his ideas than can be found in his published writing.
