Causal theory of reference

A causal tbeory of reference or historical chain tbeory of reference is a philisophical tbeory of how terms acquire specific referents based on evidence. Such tbeories have been used to describe many referring terms, particularly logical terms, proper names, and natural kind terms. In tbe case of names, for example, a causal tbeory of reference typically involves tbe following claims: • a name's referent is fixed by an original act of naming, whereupon tbe name becomes a rigid designator of that object. • later uses of tbe name succeed in referring to tbe referent by being linked to that original act via a causal chain. Weaker versions of tbe position, claim merely that, in many cases, events in tbe causal history of a speaker's use of tbe term, including when tbe term was first acquired, must be considered to correctly assign references to tbe speaker's words. Causal tbeories of names became popular during tbe 1970s, under tbe influence of work by Saul Kripke and Keith Donnellan.
