Morgenbesser's Coin and Counterfactuals with True Components
Lee Walters · Proceedings of the Aristotelian Society (Hardback) · 2009
Is A∧C sufficient for the truth of ‘If A were the case, C would be the case’? Jonathan Bennett thinks not and produces a putative counterexample. But I argue that anyone who accepts the case of Morgenbesser's coin, as Bennett does, should reject Bennett's counterexample. Moreover, I show that the principle underlying Bennett's counterexample is unmotivated and indeed false. More generally, I argue that Morgenbesser's coin commits us to the sufficiency of A∧C for the truth of the corresponding counterfactual.
