Single Idea 22303

[filed under theme 10. Modality / B. Possibility / 9. Counterfactuals ]

Full Idea

There seems to be no true proposition of which it makes sense to say that it might have been false. One might as well say that redness might have been a taste and not a colour.

Gist of Idea

It makes no sense to say that a true proposition could have been false

A Reaction

Few thinkers agree with this rejection of counterfactuals. It seems to rely on Moore's idea that true propositions are facts. It also sounds deterministic. Does 'he is standing' mean he couldn't have been sitting (at t)?

What stays the same in assessing a counterfactual antecedent depends on context [Quine]
Counterfactuals have no place in a strict account of science [Quine]
We feign belief in counterfactual antecedents, and assess how convincing the consequent is [Quine]
Counterfactuals are either based on laws, or on nearby possible worlds [Kim, by PG]
Counterfactuals are just right for analysing statements about the powers which things have [Harré/Madden]
For true counterfactuals, both antecedent and consequent true is closest to actuality [Lewis]
In good counterfactuals the consequent holds in world like ours except that the antecedent is true [Lewis, by Horwich]
Backtracking counterfactuals go from supposed events to their required causal antecedents [Lewis]
Problems with Goodman's view of counterfactuals led to a radical approach from Stalnaker and Lewis [Horwich]
Counterfactuals presuppose a belief (or a fact) that the condition is false [Mautner]
Counterfactuals are not true, they are merely valid [Mautner]
Counterfactuals are true if in every world close to actual where p is the case, q is also the case [Mautner]
Counterfactuals say 'If it had been, or were, p, then it would be q' [Mautner]
Maybe counterfactuals are only true if they contain valid inference from premisses [Mautner]
Counterfactual conditionals transmit possibility: (A□→B)⊃(◊A⊃◊B) [Williamson]
A counterfactual antecedent commands the redescription of a selected moment [Maudlin]
Counterfactuals aren't about actuality, so they lack truthmakers or a supervenience base [Merricks]
Counterfactuals are essential for planning, and learning from mistakes [Hofweber]
An improbable lottery win can occur in a nearby possible world [Pritchard,D]
Counterfactuals invite us to consider the powers picked out by the antecedent [Jacobs]
