The problem being addressed is the nature of language and communication. The project questions the old idea that language is based on a convention of cooperative information exchange. This idea was problematic in that it ignores many uses of language that are ubiquitous. For instance, language use is not always cooperative. Often times we use language in a strategic way for conflicting purposes—in the political sphere, for example, in the courtroom, and even with our children and intimate partners. Even when language is cooperative, it’s not always used for information exchange. For instance, we also use language to tell stories, to make jokes, to socially bond, to perform rituals, etc. These issues are important for society because they have implications for social sciences such as linguistics, as well as for legal and moral issues involving interpretation, free speech, and hate speech. The project has two main objectives: (1) to provide a novel metasemantic proposal, i.e. an account of what makes it the case that a community of speakers share a given language and (2) to provide a novel ontology of linguistic entities such as languages and expressions. The aim is for the findings to be published in a series of articles and a monograph.
