Abstract

For Wittgenstein's supposed private language is one which it is logically impossible to teach another and similarly impossible for anyone else to understand. The global purpose of Wittgenstein's discussion of private knowledge of experience, private ownership of experience and private ostensive definition (which might be called the private language argument in a narrow sense) is not to establish that language is essentially social. Of course, human languages are shared, and are learned in social contexts from parents, elders and siblings. That is an anthropological and psychological truth. What is distinctive about early modern philosophy was its unquestioned adoption of the concepts of ideas and impressions as the primary tools for explanation of the sources, nature and limits of knowledge and understanding, and as the foundations of language. What Wittgenstein aimed to show is not that sensation‐language, like the rest of language, is essentially shared, but that it is essentially shareable.
