Strange as it may seem, Cervantes’s novel Don Quijote, Woody Allen’s film Purple Rose of Cairo, Shakespeare’s comedy A Midsummer Night’s Dream, paintings by Magritte and Mozart’s instrumental sextet “Ein musikalischer Spaß” (’A Musical Joke’) all share one common feature: they include a meta-dimension. ‘Metaization’ – the movement from a first cognitive or communicative level to a higher one on which the first-level thoughts and utterances self-reflexively become objects of reflection and communication – is in fact a common feature not only of human thought and of language as a primary medium but also of literature and most arts as (secondary) media.
