  Adding to the confusion, “convention” frequently serves as jargon within economics, anthropology, and sociology. Even within philosophy, “convention” plays so many roles that we must ask whether a uniform notion is at work. Generally speaking, philosophical usage emphasizes the second of Goodman’s disambiguations. A common thread linking most treatments is that conventions are “up to us,” undetermined by human nature or by intrinsic features of the non-human world. We choose our conventions, either explicitly or implicitly.
