Single Idea 12150
[filed under theme 19. Language / D. Propositions / 6. Propositions Critique
]
Full Idea
The problem of the essential indexical reveals that something is badly wrong with the traditional doctrine of propositions.
Gist of Idea
Indexicals reveal big problems with the traditional idea of a proposition
Source
John Perry (The Problem of the Essential Indexical [1979], 'Prob')
Book Ref
'Self-Knowledge', ed/tr. Cassam,Quassim [OUP 1994], p.172
A Reaction
See the reaction to 12149. The traditional view of propositions, or at least Russell's view, seems to be that they are same as facts, which strikes me as daft. I take propositions to be brain events, probably expressed in mentalese.
