- Oh. Well, yes, there's THAT difference.

-
- Well, suppose someone suggested that "X is yummy" should be
- paraphrased as "MMMMM, X!" Along the lines of emotivism.
-
- As well you know, Simon Blackburn thinks that MANY predicates
- should be paraphrased out that way. He thinks these predicates
- express NO property, and yet that they are meaningful.
-
- Even if you hate Blackburn, there are more respectable examples.
- De Finetti was an expressivist about probability predicates, for
- example. Allan Gibbard has a pretty good expressivist theory of
- normative judgments.

- >So what?
-
- Ok, ok. So indexicals do express properties.
-
- I suppose what I was thinking was that there is no property of
- Yesterday Occurrence. Nevertheless, "Occurred yesterday" does
- express a property on each occasion of utterance.

-
- Perhaps they are.
-
- So I'm left with the Expressivist example.
-
- Why don't you think that's a counterexample? Is it,
- (a) because Expressivism is false,
- (b) because a predicate with an Expressivist analysis is meaningless,
- (c) because a predicate with an Expressivist analysis nonetheless
- expresses a property,
-
- or something else?
