Single Idea 12151

[filed under theme 19. Language / C. Assigning Meanings / 9. Indexical Semantics ]

Full Idea

If I leave a trail of sugar, and realise 'that I am making a mess', ...when we replace the word 'I' with other designations of me, we no longer have an explanation of my behaviour, or an attribution of the same belief, so it is an 'essential indexical'.

Gist of Idea

If we replace 'I' in sentences about me, they are different beliefs and explanations of behaviour

A Reaction

[compressed] A famous observation of Perry's, which leads him to challenge traditional accounts of belief and of propositions. I don't think I see a problem, if we have a thoroughly non-linguistic account of essentially unambiguous propositions.

The 15 ideas with the same theme [giving meanings for terms that obviously depend on context]:

6899 The references of indexicals ('there', 'now', 'I') depend on the circumstances of utterance [Mautner]
15605 I take indexicals such as 'this' and 'that' to be linked to some associated demonstration [Fine,K]
22932 We don't just describe a time as 'now' from a private viewpoint, but as a fact about the world [Le Poidevin]
16389 If two people think 'I am tired', they think the same thing, and they think different things [Recanati]
16364 Indexical don't refer; only their tokens do [Recanati]
16363 Indexicals (like mental files) determine their reference relationally, not by satisfaction [Recanati]
18408 Indexicals are just non-constant in meaning, and don't involve any special concepts [Cappelen/Dever]
18414 Fregeans say 'I' differs in reference, so it must also differ in sense [Cappelen/Dever]
18423 All indexicals can be expressed non-indexically [Cappelen/Dever]
