Truth Classification
Pragmatic Theory
A statement is true if it is useful, beneficial, or works in practice for the person or people who hold it.
Coherence Theory
A statement is true if it is consistent with or "coheres" with a larger system of beliefs that are already accepted as true.
Deflationary Theory (Redundancy)
This theory suggests that the concept of "truth" is not a substantial property of a statement, and calling a statement true simply means agreeing with it.
Semantic Theory
This theory, associated with Tarski and Davidson, provides a formal definition of truth, often seen as a version of the correspondence theory but with formal logic and semantics.
Correspondence Theory
A statement is true if it accurately reflects or "corresponds" to the actual state of the world or reality. For example, the statement "The sky is blue" is true if the sky is, in fact, blue.
The most prominent classification of truth comes from philosophical "theories of truth," There are 5 main theories of truth. Each offers a different criterion for what makes a statement true.
