taûtálogía

taūtálogía is a term used in philosophy and linguistics to describe a statement that is true by virtue of its logical structure alone. It is a statement that asserts something which is necessarily true, regardless of the empirical facts of the world. In essence, a taūtálogía is a self-evident truth.

The concept of taūtálogía is closely related to the idea of analytic statements, which are true by definition. For example, the statement "All bachelors are unmarried men" is a taūtálogía because the definition of a bachelor already includes being an unmarried man. The truth of this statement does not depend on any observation or experience.

In logic, taūtálogía are often represented by propositional logic formulas that are always true. These are known as tautologies. For instance, the statement "Either P or not P" is a taūtálogía because it is always true, whether P is true or false. If P is true, then "P or not P" is true. If P is false, then "not P" is true, making "P or not P" true as well.

The philosophical significance of taūtálogía lies in their role in establishing a foundation for knowledge. Because they are true by necessity, they can be used as starting points for logical deduction and reasoning. However, critics argue that taūtálogía, while true, do not provide any new information about the world. Their truth is purely formal and does not extend our understanding of reality. Despite this limitation, they remain a fundamental concept in logic and philosophy of language.
