Single Idea 19181

[catalogued under 3. Truth / F. Semantic Truth / 1. Tarski's Truth / a. Tarski's truth definition]

Full Idea

If we base ourselves on the classical conception of truth, we shall say that the sentence 'snow is white' is true if snow is white, and it is false if snow is not white.

Gist of Idea

In the classical concept of truth, 'snow is white' is true if snow is white


Alfred Tarski (The Semantic Conception of Truth [1944], 04)

A Reaction

I had not realised, prior to his, how closely Tarski is sticking to Aristotle's famous formulation of truth. The point is that you can only specify 'what is' using a language. Putting 'true' in the metalanguage gives specific content to Aristotle.
