Is False Dilemma Really a Formal Fallacy?

Abstract: We argue that Conces’ and Walters’ tool FM2.0 is valuable but does not show that false dilemma is a formal fallacy. The FM2.0 assumes an ambiguous use of the term ‘formal fallacy’, different from how the term is used in logic, and may show that any argument is a formal fallacy. Moreover,...

description Abstract: We argue that Conces’ and Walters’ tool FM2.0 is valuable but does not show that false dilemma is a formal fallacy. The FM2.0 assumes an ambiguous use of the term ‘formal fallacy’, different from how the term is used in logic, and may show that any argument is a formal fallacy. Moreover, the FM2.0 is developed by using one type of false disjunctive syllogism. However, the adequate application of FM2.0 on false dilemma does not lead to an invalid augmented argument, contrary to what is expected in FM2.0, even assuming the ambiguous use of the term ‘formal fallacy’. Résumé: Nous soutenons que l’outil FM2.0 de Conces et de Walters est utile mais ne démontre pas que le faux dilemme est un sophisme formel. Le FM2.0 suppose une utilisation ambiguë du terme « sophisme formel », différente de son utilisation en logique, et peut montrer que tout argument est un sophisme formel. De plus, le FM2.0 est développé en adoptant un type de faux syllogisme disjonctif. Cependant, l’application adéquate du FM2.0 au faux dilemme ne conduit pas à un argument augmenté non valide, contrairement à ce qui est attendu dans le FM2.0, même en supposant l’utilisation ambiguë du terme « sophisme formel ».
