5. Theory of Logic / E. Structures of Logic / 6. Relations in Logic
10816 We can use mereology to simulate quantification over relations [Lewis]
5. Theory of Logic / F. Referring in Logic / 1. Naming / a. Names
9038 We must distinguish what the speaker denotes by a name, from what the name denotes [Evans]
5824 How can an expression be a name, if names can change their denotation? [Evans]

15533 We can quantify over fictions by quantifying for real over their names [Lewis]
5. Theory of Logic / G. Quantification / 6. Plural Quantification
