Abstract

Abstract – The basic principle of all realist theories of truth developed in the 13th and 14th centuries was that a proposition is true if and only if it tells us how things are in reality. Walter Burley (1275-1344) interpreted this principle in a more radical way than 13th-century realists did. He proposed a correspondence theory in which there is a strict biunique correspondence between linguistic and extra-linguistic elements. If the principle of correspondence can be applied unconditionally to all affirmative utterances about present entities, it cannot apply in the case of utterances concerning past entities, which no longer exist. In order to maintain the principle of correspondence, Burley argues that such utterances, in order to be true, must not correspond to an extra-mental object, but to a complex mental object or objective entity, a mental proposition with the verb in the present tense which, was true in a past moment.
