Abstract

Through perception we gain information about the world. We also gain information about the world through communication with others. There are concepts — indexical concepts, such as the concept of the present time ('now') or of the present place ('here') or the concept of oneself — which have a special link to perception. Are there concepts which are tied to communication in the same way in which indexical concepts are tied to perception? After discussing, and criticizing, a deflationary approach to the phenomenon of deference, I argue that 'deferential concepts' are indeed the communicational equivalent of indexical concepts.
