The Wikipedia statement “Genghis Khan founded the largest contiguous empire in world history” is thus true, and the statement “Genghis Khan was one of the most successful playwrights of late Victorian London” is false.
[1] As an example for a name that fails to refer to a real object, Russell used “the present king of France“ in a 1905 article.
The first statement suffers reference failure, because it fails to pick out an individual in the actual world.
[1] In the Russellian system, the statement "Long John Silver has a wooden leg" and the statement "Long John Silver was one of the most successful playwrights of late Victorian London" have the same truth value: false.
This equality may present problems for those wishing to distinguish such statements in terms of truth value.
