Abstract
The starting point of the article is a passage in Tarski’s work entitled The Semantic Concept of Truth and the Foundations of Semantics (1944), in which he points out the difference between the concept of truth and other semantic concepts. According to Tarski, unlike other semantic concepts, “truth” does not indicate a relation but a property (property of sentences). Although Tarski did not elaborate on this claim in his seminal paper, I argue that this passage may be taken as a starting point for further considerations of the essence of truth. In particular, one of the most important issues is the classical concept of truth and the problem of correctly constructing the definition of truth understood as not a relation but a property.
