19. Language / B. Reference / 3. Direct Reference / b. Causal reference
Are causal descriptions part of the causal theory of reference, or are they just metasemantic? [Kaplan, by Schaffer,J]
     Full Idea: Kaplan notes that the causal theory of reference can be understood in two quite different ways, as part of the semantics (involving descriptions of causal processes), or as metasemantics, explaining why a term has the referent it does.
     From: report of David Kaplan (Dthat [1970]) by Jonathan Schaffer - Deflationary Metaontology of Thomasson 1
     A reaction: [Kaplan 'Afterthought' 1989] The theory tends to be labelled as 'direct' rather than as 'causal' these days, but causal chains are still at the heart of the story (even if more diffused socially). Nice question. Kaplan takes the meta- version as orthodox.
Causal theories of reference (by 'dubbing') don't eliminate meanings in the heads of dubbers [Rey]
     Full Idea: Causal histories may have some role to play in a theory of reference, but the chain of causation requires internal characterisations at each stage, and the original dubber had one thing rather than another in mind when dubbing.
     From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.1)
     A reaction: The modern view of direct reference seems to prefer social context rather than a complete causal chain.
If meaning and reference are based on causation, then virtually everything has meaning [Rey]
     Full Idea: What is special about meaning? If meaning and reference are just the result of causal chains, almost everything will mean something, since almost everything is reliably caused by something.
     From: Georges Rey (Contemporary Philosophy of Mind [1997], 9.2.2)
     A reaction: It would be insane to think that all causal events produced meanings. It is probably better not to mention causation at all when discussing meaning.
19. Language / B. Reference / 4. Descriptive Reference / a. Sense and reference
Referential Opacity says truth is lost when you substitute one referring term ('mother') for another ('Jocasta') [Rey]
     Full Idea: Referential Opacity says you cannot preserve truth if you substitute one referring term for another ('Oedipus desires Jocasta', 'Oedipus desires his mother').
     From: Georges Rey (Contemporary Philosophy of Mind [1997], 2.5.6)
     A reaction: ….That is, in the context of expressing a propositional attitude. 'Oedipus desired his mother' was true. This idea requires some ignorance on the part of the person expressing the thought.
