 The diagonal proposition view seems to avoid many of the difficulties of other approaches to narrow content. In particular, it does provide truth conditions, and hence seems clearly to be a kind of content. (However, Kriegel (2008) points out that, while two-dimensional accounts like this one and the epistemic account to be discussed next can provide truth conditions for “the mental analog of a sentence” and thus explain how it “puts us in cognitive contact with a state of affairs that constitutes its potential truth maker” (305), it is not so clear how the account can associate the mental analogs of subsentential expressions with worldly things and properties. Kriegel offers an account according to which concepts, the mental analogs of predicate terms, denote response-dependent properties.)
