Abstract: The two-dimensional modal framework deployed in Chs. and 6 is used to describe some puzzles about belief discussed in two papers by Brian Loar, and some theoretical ideas that he develops in response to those puzzles. I argue that Loar's notion of realization conditions, which he distinguishes from truth conditions, can be identified with my notion of a diagonal proposition. The main claim is that while the framework lends support to some of Loar's explanations of the examples, it does not yield a notion of narrow content.
