Abstract
There are two main models for explaining Frege's notion of sense, both of which have their roots in the work of Sir Michael Dummett. One, nowadays most familiar from the work of David Chalmers, is broadly internalist and descriptivist in character. The other, most familiar from the work of Gareth Evans, is externalist and anti-descriptivist. I first consider the former project, arguing that Dummett anticipated Chalmers's version of the view, and that no version of this view is going to be defensible. The arguments are somewhat different from those familiar from the literature. I then consider Evans's view and argue that, while it is not vulnerable to many of the objections that have been made to it, it does not really succeed as an account of sense, because it forces us to abandon Frege's view that sense is an aspect of representational content.
