Some appeals to haecceities in the philosophy of language are more limited and nuanced—e.g., Hawthorne and Manley (2012: 204) consider the deployment of haecceities and other non-qualitative properties in a semantics for demonstratives—while other applications are more general in scope—e.g., analyses of de re senses or individual concepts in terms of haecceities. (For discussion, see Chisholm (1976: 29).)
