Single Idea 16448

[filed under theme 19. Language / C. Assigning Meanings / 8. Possible Worlds Semantics ]

Full Idea

Most theorists agree that possible worlds semantics cannot provide an analysis of modal concepts which is an eliminative reduction, but it can still provide an explanation of the meanings of modal expressions.

Gist of Idea

Possible world semantics may not reduce modality, but it can explain it

A Reaction

Stalnaker cites Kit Fine for the view that there is no reduction of modality, which Fine takes to be primitive. Stalnaker defends the semantics, while denying the reduction which Lewis thought possible.


The 27 ideas from 'Mere Possibilities'

Given actualism, how can there be possible individuals, other than the actual ones? [Stalnaker]
Some say what exists must do so, and nothing else could possible exist [Stalnaker]
Modal concepts are central to the actual world, and shouldn't need extravagant metaphysics [Stalnaker]
Possible worlds are properties [Stalnaker]
A nominalist view says existence is having spatio-temporal location [Stalnaker]
Necessity and possibility are fundamental, and there can be no reductive analysis of them [Stalnaker]
I don't think Lewis's cost-benefit reflective equilibrium approach offers enough guidance [Stalnaker]
Properties are modal, involving possible situations where they are exemplified [Stalnaker]
Possible worlds don't reduce modality, they regiment it to reveal its structure [Stalnaker]
I think of worlds as cells (rather than points) in logical space [Stalnaker]
I take propositions to be truth conditions [Stalnaker]
A theory of propositions at least needs primitive properties of consistency and of truth [Stalnaker]
Propositions presumably don't exist if the things they refer to don't exist [Stalnaker]
Possible world semantics may not reduce modality, but it can explain it [Stalnaker]
In modal set theory, sets only exist in a possible world if that world contains all of its members [Stalnaker]
Anti-haecceitism says there is no more to an individual than meeting some qualitative conditions [Stalnaker]
Dispositions have modal properties, of which properties things would have counterfactually [Stalnaker]
The bundle theory makes the identity of indiscernibles a necessity, since the thing is the properties [Stalnaker]
Modal properties depend on the choice of a counterpart, which is unconstrained by metaphysics [Stalnaker]
We still lack an agreed semantics for quantifiers in natural language [Stalnaker]
We regiment to get semantic structure, for evaluating arguments, and understanding complexities [Stalnaker]
In 'S was F or some other than S was F', the disjuncts need S, but the whole disjunction doesn't [Stalnaker]
'Socrates is essentially human' seems to say nothing could be Socrates if it was not human [Stalnaker]
Strong necessity is always true; weak necessity is cannot be false [Stalnaker]
Non-S5 can talk of contingent or necessary necessities [Stalnaker]
I accept a hierarchy of properties of properties of properties [Stalnaker]
How can we know what we are thinking, if content depends on something we don't know? [Stalnaker]
