“If someone wishes to speak in his language about a new kind of entities, he has to introduce a system of new ways of speaking, subject to new rules; we shall call this procedure the construction of a linguistic framework for the new entities in question.”

“I feel impelled to speak today in a language that in a sense is new”
1950s, Atoms for Peace (1953)
Context: I feel impelled to speak today in a language that in a sense is new--one which I, who have spent so much of my life in the military profession, would have preferred never to use. That new language is the language of atomic warfare. The atomic age has moved forward at such a pace that every citizen of the world should have some comprehension, at least in comparative terms, of the extent of this development of the utmost significance to every one of us. Clearly, if the people of the world are to conduct an intelligent search for peace, they must be armed with the significant facts of today's existence.
