Causal Theory of Reference - Kripke's Causal Account of Names

Kripke's Causal Account of Names

In lectures later published as Naming and Necessity, Kripke provided a rough outline of his causal theory of reference for names. Although he refused to explicitly endorse such a theory, he indicated that such an approach was far more promising than the then-popular descriptive theory of names introduced by Russell, according to which names are in fact disguised definite descriptions. Kripke argued that in order to use a name successfully to refer to something, you do not have to be acquainted with a uniquely identifying description of that thing. Rather, your use of the name need only be caused (in an appropriate way) by the naming of that thing.

Such a causal process might proceed as follows: the parents of a newborn baby name it, pointing to the child and saying "we'll call her 'Jane'." Henceforth everyone calls her 'Jane'. With that act, the parents give the girl her name. The assembled family and friends now know that 'Jane' is a name which refers to Jane. This is referred to as Jane's dubbing, naming, or initial baptism.

However, not everyone who knows Jane and uses the name 'Jane' to refer to her was present at this naming. So how is it that when they use the name 'Jane', they are referring to Jane? The answer provided by causal theories is that there is a causal chain that passes from the original observers of Jane's naming to everyone else who uses her name. For example, maybe Jill was not at the naming, but Jill learns about Jane, and learns that her name is 'Jane', from Jane's mother, who was there. She then uses the name 'Jane' with the intention of referring to the child Jane's mother referred to. Jill can now use the name, and her use of it can in turn transmit the ability to refer to Jane to other speakers.

Philosophers such as Gareth Evans have insisted that the theory's account of the dubbing process needs to be broadened to include what are called 'multiple groundings'. After her initial baptism, uses of 'Jane' in the presence of Jane may, under the right circumstances, be considered to further ground the name ('Jane') in its referent (Jane). That is, if I am in direct contact with Jane, the reference for my utterance of the name 'Jane' may be fixed not simply by a causal chain through people who had encountered her earlier (when she was first named); it may also be indexically fixed to Jane at the moment of my utterance. Thus our modern day use of a name such as 'Christopher Columbus' can be thought of as referring to Columbus through a causal chain that terminates not simply in one instance of his naming, but rather in a series of grounding uses of the name that occurred throughout his life. Under certain circumstances of confusion, this can lead to the alteration of a name's referent (for one example of how this might happen, see Twin Earth thought experiment).
