La ricerca della lingua perfetta nella cultura europea (The Search for the Perfect Language (the Making of Europe); trans.
James Fentress) is a 1993 book by Umberto Eco about attempts to devise an ideal language.
The writing is essayistic and uses the myth of Babel as a paradigm for connecting linguistic and social practices.
Lengthy passages are devoted to Dante, Lull, Kircher, various 17th-century authors and a few less well-known names from later times.
The contemporary project for a politically and culturally unified Europe provides the perspective for a more serious consideration of the theme.
