 Popper made the first attempt to solve the problem in his famous collection Conjectures and Refutations. As a great admirer of Tarski’s assay on the concept of truth, he modelled his theory of truthlikeness on Tarski’s theory. First, let a matter for investigation be circumscribed by a formalized language \(L\) adequate for discussing it. Tarski showed us how each possible world, or model of the language, induces a partition of sentences of \(L\) into those that are true and those that are false. The set of all sentences true in the actual world is thus a complete true account of the world, as far as that language goes. It is aptly called the Truth, \(T\). \(T\) is the target of the investigation couched in \(L\). It is the theory (relative to the resources in \(L)\) that we are seeking. If truthlikeness is to make sense, theories other than \(T\), even false theories, come more or less close to capturing \(T\).
