-
- I didn't say, of course, that expressivism is bereft of an ontology
- of properties. Expressivists may be quite happy with some properties,
- but wish to rid their ontology of others.
-
- I will fill in a couple of the examples now.
-
- Blackburn claims that "is good" expresses no property, but that
- it is nevertheless meaningful, because it has a function other
- than expressing a property. Its function is to express an
- attitude ("express" in this sentence is meant in a different
- sense from that of "expresses a property").
- (He says roughly the same thing about "causes" and "is necessary.")
-
- De Finetti believed that the predicate "Has probability .5"
- expressed no property, but that it was nevertheless meaningful
- in that it expressed the speaker's degree of belief. (Again,
- "expressed" in the second sense. Perhaps I will try to avoid
- this locution, but it's not easy since the name of the view
- is "expressivism.")

-
- Which claim?
-

- >At the moment, I do not quite know what it is.
-
- I would now like to add another possibility,
-
- (d) because the things that look like predicates are not,
- according to an Expressivist analysis, really predicates at all.
