It‟s reasonable to think the consequent would be true if the antecedent were, when that involves the fewest differences with the world outlined by Gettier. - Nozick is not saying that it is logically necessary that if p were false, Smith would have believed it. - Necessary truths are true in all possible worlds. - Contingent truths are true in some possible worlds but false in others. -It is the truth of the antecedent and the assumption that we are considering the closest possible world that leads to the consequent. - This is just a small adjustment in how we‟v
