Abstract
A “slingshot” proof suggested by Kurt Gödel (1944) has been recast by Stephen Neale (1995) as a deductive argument showing that no non-truthfunctional sentence connective can permit the combined use, within its scope, of two truth-functionally valid inference principles involving defi- nite descriptions. According to Neale, this result provides indirect support for Russell’s Theory of Descriptions and has broader philosophical repercussions because descriptions occur in non-truth-functional constructions used to motivate talk about (e.g.) necessity, time, probability, causation, obligation, facts, states of affairs, and propositions.
