A Description of Finnegans Wake
Salvatore spoke all languages, and no language. Or, rather, he had invented for himself a language which used the sinews of the languages to which he had been exposed—and once I thought that his was, not the Adamic language that a happy mankind had spoken, all united by a single tongue from the origin of the world to the Tower of Babel, or one of the languages that arose after the dire event of their division, but precisely the Babelish language of the first day after the divine chastisement, the language of primeval confusion. Nor, for that matter, could I call Salvatore’s speech a language, because in every human language there are rules and every term signifies ad placitum a thing, according to a law that does not change, for man cannot call the dog once dog and once cat, or utter sounds to which a consensus of people has not assigned a definite meaning, as would happen if someone said the word “blitiri” And yet, one way or another, I did understand what Salvatore meant, and so did the others. Proof that he spoke not one, but all languages, none correctly, taking words sometimes from one and sometimes from another. I also noticed afterward that he might refer to something first in Latin and later in Provençal, and I realized that he was not so much inventing his own sentences as using the disiecta membra of other sentences, heard some time in the past, according to the present situation and the things he wanted to say, as if he could speak of a food, for instance, only with the words of the people among whom he had eaten that food, and express his joy only with sentences that he had heard uttered by joyful people the day when he had similarly experienced joy.
