Single Idea 14697

[filed under theme 19. Language / C. Assigning Meanings / 7. Extensional Semantics ]

Full Idea

A simple extensional semantics will assign the same semantic value to 'Roger Federer' and 'world's best tennis player', but they clearly differ in meaning, and if events had unfolded differently they would pick out different people.

Gist of Idea

'Federer' and 'best tennis player' can't mean the same, despite having the same extension

A Reaction

You would think that this would be too obvious to need pointing out, but it is clearly a view that had a lot of popularity before the arrival of possible worlds.


The 19 ideas from 'Two-Dimensional Semantics'

Semantic theories show how truth of sentences depends on rules for interpreting and joining their parts [Schroeter]
Simple semantics assigns extensions to names and to predicates [Schroeter]
'Federer' and 'best tennis player' can't mean the same, despite having the same extension [Schroeter]
Possible worlds semantics uses 'intensions' - functions which assign extensions at each world [Schroeter]
Possible worlds make 'I' and that person's name synonymous, but they have different meanings [Schroeter]
Array worlds along the horizontal, and contexts (world,person,time) along the vertical [Schroeter]
If we introduce 'actually' into modal talk, we need possible worlds twice to express this [Schroeter]
Superficial necessity is true in all worlds; deep necessity is thus true, no matter which world is actual [Schroeter]
Do we know apriori how we refer to names and natural kinds, but their modal profiles only a posteriori? [Schroeter]
2D semantics gives us apriori knowledge of our own meanings [Schroeter]
Your view of water depends on whether you start from the actual Earth or its counterfactual Twin [Schroeter]
Rationalists say knowing an expression is identifying its extension using an internal cognitive state [Schroeter]
Possible worlds semantics implies a constitutive connection between meanings and modal claims [Schroeter]
2D fans defend it for conceptual analysis, for meaning, and for internalist reference [Schroeter]
Contradictory claims about a necessary god both seem apriori coherent [Schroeter]
2D semantics can't respond to contingent apriori claims, since there is no single proposition involved [Schroeter]
Internalist meaning is about understanding; externalist meaning is about embedding in a situation [Schroeter]
In the possible worlds account all necessary truths are same (because they all map to the True) [Schroeter]
Semantic theory assigns meanings to expressions, and metasemantics explains how this works [Schroeter]
