Gappy Propositions and the Nature of Rigidity

<p>During the 1980s, there was much debate as to whether the potential rigidity of names allowed for such terms to refer to their objects in worlds where that object did not exist. Those who supported this idea supported an obstinate account of rigidity, and those who rejected the idea supported an account of persistent rigidity. No clear conclusion was ever reached between the two sides. In this thesis, I will raise a novel argument in support of persistent rigidity using a modern theory about singular propositions known as the gappy proposition view. My conclusion is that such a view can help resolve the earlier debate about the nature of rigidity by showing how gappy propositions may be utilised to undermine the strongest arguments once raised by the obstinate rigidity theorists.</p>
