Article Summary

Game-theoretic semantics (GTS) uses concepts from game theory to study how the truth and falsity of the sentences of a language depend upon the truth and falsity of the language’s atomic sentences (or upon its sub-sentential expressions). Unlike the Tarskian method (which uses recursion clauses to determine satisfaction conditions for nonatomic sentences in terms of the satisfaction conditions of their component sentences, then defines truth in terms of satisfaction), GTS associates with each sentence its own semantic game played on sentences of the language. This game defines truth in terms of the existence of a winning strategy for one of the players involved. The structure of the game is determined by the sentence’s structure, and thus the semantic properties of the sentence in question can be studied by attending to the properties of its game.
