Descriptivist theory of names is a view of the nature of the meaning and reference of proper names generally attributed to Gottlob Frege and Bertrand Russell. The theory consists essentially in the idea that the meanings (semantic contents) of names are identical to the descriptions associated with them by speakers, while their referents are determined to be the objects that satisfy these descriptions.
In the 1970s, this theory came under strong attack from causal theorists such as Saul Kripke, Hilary Putnam and others. However, it has seen something of a revival in recent years, especially under the form of what are called two-dimensional semantic theories. This latter trend is exemplified by the theories of David Chalmers, among others.
