  In what precedes, we have looked at the semantics of various kinds of sentences where mass nouns appear. But we haven’t considered whether there are logical relations between such sentences, i.e., whether the semantics makes up for an adequate logic of mass nouns. This is the topic of this section. An appropriate semantics for mass nouns should guarantee things like what follows. (For a more detailed discussion, see Pelletier &amp; Schubert 2003: 63–74.)
