Abstract

According to Hector-Neri Castañeda, indexical reference is our most basic means of identifying the objects and events we experience and think about. Its tokens reveal our own part in the process by denoting what are "referred to as items present in experience" (Castañeda 1981, 285-6). If you hear me say, "Take that box over there and set it next to this box here," you learn something about my orientation towards the referents in a way that is not conveyed by, "Take the red box and set it next to the blue box." My indexical tokens express what they do not only because they issue from a unique spatio-temporal perspective that I happen to occupy, but also because they reflect my encounter with referents that are differently situated in that perspective. From your perspective, my here might be your there, my you your she, and within my own, a this differs from a that and one this diverges from another. Encounter and orientation within a perspective are the essential ingredients in indexical identification without which particular 'this's, 'that's, 'then's, 'here's, and 'beyond's would be denuded of individuating powess.1 There are several consequences of this description. First, indexical reference is ephemeral because perspective is constantly changing, rendering the indexical status of an entity relative to a given perspective temporary: 1 A this quickly turns into a that, and soon enough it is lost to experience and is not even a remote that; a you goes away and is replaced by another . . . Nothing is really an enduring you -- except God perhaps for the abiding mystic. (Castañeda 1989a, 69) Second, indexical reference is irreducible since non-indexical mechanisms of reference fail to express the subject's involvement or encounter with the referents that indexicals convey. Nor can the various indexicals be reduced to each other.2 Third, because each perspective is unique, indexical reference is essentially subjective..
