Wittgenstein said that "If a lion could speak, we cannot understand it". He also said that a private language is not possible. In my view, structuralism and post-structuralism also talk about these ideas in the sense that it is not possible to understand the author's intention because the meaning of the language is determined by the cultural context. There seems to be a lot of similarity between these ideas for me. However, I do not see anyone attributing the credits for the ideas in structuralism and post-structuralism to Wittgenstein.
My question is, did Wittgenstein's ideas on language contribute something to structuralism and post-structuralism?
