The picture theory of language, also known as the picture theory of meaning, is a theory of linguistic reference and meaning articulated by Ludwig Wittgenstein in the Tractatus Logico-Philosophicus. Wittgenstein suggested that a meaningful proposition pictured a state of affairs or empirical fact.[1][2] Wittgenstein compared the concept of logical pictures with spatial pictures.[3] The picture theory of language is considered an early correspondence theory of truth.[4]
Wittgenstein's picture theory of language states that statements are meaningful if they can be defined or pictured in the real world.
