Editing Causal theory of reference (section)

{{Short description|Theory that terms acquire referents via a chain of usage events}}
A '''causal theory of reference''' or '''historical chain theory of reference''' is a theory of how terms acquire specific [[reference|referents]] based on evidence. Such theories have been used to describe many referring terms, particularly logical terms, [[proper names]], and [[natural kind]] terms. In the case of names, for example, a causal theory of reference typically involves the following claims:

* a name's [[reference|referent]] is fixed by an original act of naming (also called a "dubbing" or, by [[Saul Kripke]], an "initial baptism"), whereupon the name becomes a [[rigid designator]] of that object.
* later uses of the name succeed in referring to the referent by being linked to that original act via a [[Causality|causal chain]].

Weaker versions of the position (perhaps not properly called "causal theories") claim merely that, in many cases, events in the causal history of a speaker's use of the term, including when the term was first acquired, must be considered to correctly assign references to the speaker's words.

Causal theories of names became popular during the 1970s, under the influence of work by Saul Kripke and [[Keith Donnellan]]. Kripke and [[Hilary Putnam]] also defended an analogous causal account of [[natural kind]] terms.
