Germany is divided into more governments than the neighboring kingdoms.... However, a common genius prevails everywhere among people speaking the same language” (Emmanuel Swedenborg, 1771.)

ii. “The diversity of languages is not a diversity of signs and sounds but a diversity of views of the world” (Wilhelm von Humboldt, 1820.)
