Abstract
Focusing on the simple demonstrative ‘that’ and demonstrative expressions of the form ‘that F,’ this paper reviews four accounts of what determines the denotations of demonstratives—the description theory, according to which the work is done by a proper definite description associated with the demonstrative; the causal theory, according to which it is done by a non-deviant causal chain connecting the object and the demonstrative; the demonstration theory, according to which it is done by a demonstration accompanying the demonstrative; and the mental reference theory, according to which it is done by the mental act of reference that the demonstrative expresses—and it offers evidence of the superiority of the mental reference theory.
