Veritas Est Adaequatio Intellectus Et Rei: Untersuchungen Zur Wahrheitslehre Des Thomas Von Aquin Und Zur Kritik Kants an Einem Uberlieferten Wahrhe ... Des Mittelalters) (German Edition)

One of the key doctrines of the philosophy of Thomas Aquinas is his definition of truth as "adaequatio intellectus et rei," The aim of this study is to make clear that the medieval doctrine presents the essential meaning of the term 'truth'. Thomas' doctrine of truth is developed in his "Quaestiones disputatae de veritate," Only careful analysis of the first "quaestio" allows a precise formulation of the classical definition of truth. For only after Thomas' doctrine of truth has been integrated into his ontology and his theory of meaning, can the meanings of "adaequatio," "intellectus" and "res" be understood. After reconstructing Thomas' theory of truth, the author turns to Kant's discussion of traditional notions of truth. Kant's doctrine is taken as representative of that of a number of modern thinkers, as he is held to be the founder of the coherence theory of truth (as against the correspondence theory). An analysis of Kant's critique leads to the unexpected realisation that he maintains the classical definition. The study of selected texts throws light on the much discussed continuity between medieval and modern thought.
