Abstract

In chapter one I consider two arguments for the claim that we ought to attribute linguistic knowledge to speakers of a natural language. The a priori argument has it that a theory of understanding reveals what it is that speakers of a language know about their language. The second argument takes the form of an inference to the best explanation, emphasising the idea that speaking and understanding a language is a rational activity carried on by agents with intention and purpose. Linguistic knowledge is attributed to speakers as a way of making such a practice intelligible. ;In chapter two, I examine the several sceptical worries and substantive objections that have been raised to the idea of linguistic knowledge. None of these objections is fatal; rather they direct our attention to the need to specify what kind of knowledge linguistic knowledge is. ;In chapter three I argue that we do best to think of the notion of implicit linguistic knowledge as a "place-holder". ;In chapter four, I turn to a discussion of implicit belief, drawing a distinction between the way in which the content of a belief might be represented in an agent's brain and the kind of access she has to that content. I argue against an account of implicit belief that is motivated by concerns about representation, and for one that focuses on the kind of access an agent has to her implicit beliefs. ;In chapter five I attempt to sketch an account of implicit linguistic knowledge that fulfills its explanatory agenda while avoiding the objections discussed in earlier chapters. A speaker's implicit linguistic knowledge, understood as a set of articulated psychological states, grounds her full-blooded linguistic dispositions. This analysis of implicit linguistic knowledge is not subject to standard objections to that notion. Furthermore, it provides a "non-reductive" explanation of a speaker's language mastery, since it holds a middle ground between strictly biological, or neurophysiological accounts and purely behavioristic accounts of what makes an agent a speaker of a language. ;Finally, I take up the question of whether Dummett can accept my account of implicit linguistic knowledge
