The subject of meaning in natural language is currently investigated both by philosophers and linguists, with different foci, methods, and emphasis. The two are typically guided by different concerns and goals (e.g., linguists are centrally concerned with patterns of cross-linguistic variation and language acquisition; philosophers investigate the normativity of language and the metaphysical presuppositions of particular theoretical claims), but both groups can profit from cross-disciplinary discussions and mutual understanding of their different questions, methods, and results. The 2009-10 Workshop will focus on contextualism.
