While reading an influential text on direct reference, I found the following claim:
In the framework I have just sketched, a proper name is a word which must be used in a certain way, even though it may happen to be used in other ways.
I don’t know how to interpret this in a non-inconsistent, or non-contradictory, way. I wonder, more specifically, how the quoted text differs from the following:
According to the rules we have just stipulated, you must come home every night at 8, even though you may come at other times.
