10. Modality / B. Possibility / 8. Conditionals / d. Non-truthfunction conditionals
Conditionals are true if minimal revision of the antecedent verifies the consequent
                        Full Idea: Stalnaker proposes that a conditional is true if its consequent is true in the minimal revision in which the antecedent is true, that is, in the most similar possible world in which the antecedent is true.
                        From: report of Robert C. Stalnaker (works [1970]) by Stephen Read - Thinking About Logic Ch.3
                        A reaction: A similar account of counterfactuals was taken up by Lewis to give a (rather dubious) account of causation.
