 Finally, Donnellan (1972) and Kripke (1980) both argued that the Descriptive Theory of Names suffers from an important epistemological defect. The descriptions that we associate with names routinely do not describe the individuals that we intend to refer to. Asked to come up with a description to substitute for the name ‘Einstein’, many people would write ‘The inventor of the atom bomb’ (which of course he was not). Others might write ‘the inventor of the theory of relativity’, but then asked what the theory of relativity was would respond ‘the theory that Einstein invented’. The descriptive information that we associate with names just is not sufficient to pick out the intended referent.
