Is 'the First Person' a linguistic concept essentially?

Abstract

The notion of 'the first person' is centrally invoked in philosophical discussions of selfhood, subjectivity, and personhood. We ask whether this notion, as invoked in these discussions, is con-tingently or essentially a grammatical term. While it is logically possible that the linguistic dimensions of self-reference are accidental to this phenomenon, we argue that no explications of such phenomena as 'reference de se' or 'essential indexicality' in non-grammatical terms has been or likely can be provided, since grammatical factors uniquely co-vary with the forms of self-reference in question. The role of grammar is reinforced by the fact that species-specific forms of reference are never purely lexical and always have a structural signature involving specific grammatical configurations; and by findings that in cognitive disorders independently characterized as disorders of selfhood, such as autism spectrum conditions, the pronominal system proves to be a particular locus of vulnerability. We conclude that grammar and human-specific forms of selfhood form an inextricable unity, inviting renewed attention to language as a constitutive condition of personhood in at least some of its forms.
