This thinker's best-known work ends with the line "What we cannot speak about we must pass over in silence." He used several examples of language games in his Blue and Brown Books, while another of his works uses the thought experiment of a "beetle-in-a-box" to argue against the idea of a private language.

For 10 points, name this 20th century philosopher of Tractatus Logico-Philosophicus.
