The Metaphysics of Thirteenth Century Dialectic and Consequences: Metaphysics, Modal Conditionals, and Consequences in Thomas Aquinas

Among medieval studies, one of the areas of debate is whether consequences arose from dialectic or from Prior Analytic commentaries and the place of metaphysics in this development. The following work investigates this development using modal conditional semantics and consequences. The work suggests conditional syllogistics led to the rise of consequences from both dialectic and developments in conditional expressions. Due to Aquinas¿ emphasis upon metaphysics and his use of conditional expressions, Aquinas is an exceptional source for a scientific investigation. The following work illustrates Aquinas' modal conditional semantic metaphysics and its relation to consequences within its Parisian context. The focus is specifically on the metaphysics of modal semantics in hypothetical modal conditional enunciations and syllogistics using the topic from definition. This scientific investigation contributes to the history of logic, the relationship between consequences, dialectic, metaphysics, and modal conditional expressions, and contemporary analytic research in conditional logic, language, and semantic theories in intensional logics.
