Speakers are confused about identity if they mistake one thing for two or two things for one. I present two plausible models of confusion, the Frege model and the Millikan model. I show how a prominent objection to Fregean models fails and argue that confusion consists in having false implicit beliefs involving the identity relation. Further, I argue that confused identity has characteristic corruptive effects on singular cognition and on the proper function of singular terms in linguistic communication.

Many philosophers have argued or taken for granted that Frege's puzzle has little or nothing to do with identity statements. I show that this is wrong, arguing that the puzzle can only be motivated relative to a thinker's beliefs about the identity or distinctness of the relevant object. The result is important, as it suggests that the puzzle can be solved, not by a semantic theory of names or referring expressions as such, but simply by a theory of identity statements. (...) To show this, I sketch a framework for developing solutions of this sort. I also consider how this result could be implemented by two influential solutions to Frege's puzzle, Perry's referential-reflexivism and Fine's semantic relationism. (shrink)

It's generally agreed that, for a certain a class of cases, a rational subject cannot be wrong in treating two elements of thought as co-referential. Even anti-individualists like Tyler Burge agree that empirical error is impossible in such cases. I argue that this immunity to empirical error is illusory and sketch a new anti-individualist approach to concepts that doesn't require such immunity.
