Abstract

This dissertation defends an account of linguistic meaning and propositional mental content in terms of linguistic practice. In other words, it clarifies and defends the counterintuitive claim that linguistic communication is prior, rather than posterior, in the order of explanation to the semantic features of thought and talk. The project's point of departure is Robert Brandom's comprehensive recent theory of linguistic practice. Two core theses characterize Brandom's theory. First, meaning and content are to be understood in terms of the norms of inference relating the sentences of a natural language to each other. Second norms of inference are to be explained in terms of certain normative attitudes that speakers take towards each other implicitly in linguistic practice. In the sense of the second explanatory thesis, linguistic practice explains meaning and content qua norms of inference, according to Brandom. ;For the sake of my project I agree with both theses. However, I take issue with Brandom's efforts to substantiate the second, explanatory thesis. The negative parts of my project argue that Brandom's specific account of meaning and content in terms of implicit normative attitudes is in some respects underdeveloped and in other respects problem laden. It therefore needs both elaboration and revision. The positive parts of my project offer an alternative account of meaning and content in terms of implicit non-native attitudes---an account that avoids the shortcomings of Brandom's approach. The heart of this alternative account is the notion of a we-attitude, borrowed from Wilfrid Sellars' theory of moral judgments. I argue that if speakers take such we-attitudes towards the linguistic performances they exchange, they both take certain implicit normative attitudes towards each other and recognize themselves as bound by the corresponding norms. And normative attitudes thus conceived suffice, I argue, to explain norms of inference themselves, hence meaning and content. Central themes of this project are, among other, the objectivity of semantic norms, the possibility to reduce semantic norms to normative attitudes, and the holistic character of meaning
