Are Concepts Public?

Jerry Fodor has argued that concepts ought to be public in order to figure in psychological explanations and in accounts of linguistic communication, and that no theory of concepts as structured abilities of categorization can account for publicity. Recently Andy Clark and Jesse Prinz opposed this latter claim, and suggested that the publicity constraint is less demanding than Fodor thinks. In this paper I support Clark and Prinz’s position through disambiguating the publicity constraint, and arguing that linguistic communication enhances concept publicity rather than requiring it.
