 An alternative riff on these ideas which has been widely discussed, but not, so far as I know, published, would be to suppose that there is a rigid property of being Aristotle—one that only Aristotle could have in any possible world (this property would be completely independent of being named ‘Aristotle’). The idea is that the content of the description could consist solely of that property. For example, when we say that ‘Aristotle might have been run over by a chariot’ we would in effect be saying there is a possible world in which the unique individual who has the property of being Aristotle was run over by a chariot. It seems that charges of circularity are not so easily advanced here, although the view does raise questions about the nature of these rigid properties and our epistemic access to them. (See Parsons (1982) for an account of the logic of rigid properties.)
