For Joyce, nationalism was a reactionary politics. As Len Platt wrote in an introductory essay to Finnegans Wake, Joyce came to decry all form of nationalism, linking it to racism and eugenic movements. The language he invented for Finnegans Wake, “Wakesese,” actively resisted nationalism, monoculturalism, and monolingualism.
For Luhmann, meaning is an actualization or selection from an uncrossable horizon of possibilities. Meaning is a two-sided form with the actualized meaning on the marked side and all the other potential/unselected meanings on the unmarked side. The communication system selects a meaning from a horizon of possibilities.
