Def Counterfactual Conditional Operator/Stalnaker/Co.Co. Operator/Cresswell: a >> b is true in a possible world w iff in the next possible world in which a is true, b is also true - Lewis (1973): more sophisticated version: without the assumption that there is an unambiguously next possible world (most similar world) - most similar world: the "selection function" that picks out the next possible world is specified in all of these theories by the model - still, the canonical intensional model should represent how the physical world works and has the structure that is imposed on it by T.
