Summary/Abstract: In this article, I discuss the theory of truth proposed by Haim Gaifmanfrom the perspective of dealing with various problematic sentences. Iintend to show that this concept is open to serious objections as much as Saul Kripke’s related theory. The theory is motivated by the strong liar puzzle and tries to solve it correctlyin a formally precise way.According to Gaifman, we should assign truth values not to sentence types, but to their tokens. The truth value of token depends on not only its sentence type, but also the network among tokens. Hence the presented theory is a paradigm of the contextual theory of truth. Two tokens of the same sentence type might have different truth values. For generality Gaifman prefers to use the term pointerinstead of token. Truth value is assigned to pointer by the algorithm called pointer semantics. The paper contains an exposition of the technical apparatus of the theory and its disadvantages.
