WebThe proof of Hintikka’s lemma is more than just evidence for the completeness of the tableau method. It shows us how to find acounterexamplefor a formulaXthat is not a tautology. We only have to construct a complete tableau for the formula, look at an open path, and use the interpretation v 0constructed in the proof. WebThe key to the completeness proof was the use of Hintikka’s lemma, which states that every downward saturated set, finite or not, is satisfiable. We then showed that every …
