Why first language learning is not second language learning ? Wittgenstein's rejection of St. Augustine's conception of learning

Abstract

The Philosophical Investigations starts with a quotation from St. Augustine on language learning. The usual reconstruction of Wittgenstein's criticism of St. Augustine's view on language focusses on meaning — that is, the picture theory which he had in common with Wittgenstein's own earlier views. This paper shows that Wittgenstein in discussing ostensive definition, understanding, and the private language argument also attacks St. Augustine's notion of learning. In recent years the Augustinian conception has been resurrected in cognitive theories postulating an innate language of thought (e.g., Fodor), making Wittgenstein's claims that this conception of learning is paradoxical very relevant.
