There have been many attempts to define truth in terms of correspondence, coherence or other notions. However, it is far from clear that truth is a definable notion. In formal settings satisfying certain natural conditions, Tarski’s theorem on the undefinability of the truth predicate shows that a definition of a truth predicate requires resources that …
