Tarski’s Convention T: A Correspondence Theory of Truth

Understanding Tarski’s Convention T

Convention T, introduced by Alfred Tarski, offers a pivotal approach to understanding truth. It posits that a statement is true if and only if it corresponds to the facts in the world.

Key Concepts

The core idea revolves around the correspondence theory of truth. A sentence like ‘Snow is white’ is true if and only if snow is, in reality, white. This establishes a direct link between language and the world.

Deep Dive into Convention T

Tarski formalized this by suggesting that for any given predicate P, the sentence ‘P holds of x’ is true if and only if x is P. This definition aims for truth-aptness and avoids paradoxes common in earlier theories.

Applications and Implications

Convention T has significant implications for logic, semantics, and philosophy of language. It provides a framework for defining truth in formal languages and understanding how we assert truths about the world.

Challenges and Misconceptions

One challenge lies in defining ‘facts’ or ‘reality’ precisely. Misconceptions often arise regarding whether Convention T is a full theory of truth or merely a criterion for adequacy.
