Voyage au bout de la nuit
In "Journey to the End of the Night", Céline developed a unique literary language based on the spoken French of the working class, medical and nautical jargon, neologisms, obscenities, and the specialised slang of soldiers, sailors and the criminal underworld. Reviewing the novel in 1932, a critic for "Les Nouvelles Littéraires" praised its “extraordinary language, the height of the natural and the artificial” while the critic for "Le Populaire de Paris" condemned it as mere vulgarity and obscenity.
