Like 1984, this is a book in which an entire social order is implied through language. And what language! To hint at the vile universe of the 15-year-old delinquent Alex and his murderous buddies, Burgess created “nadsat,” a rich futuristic patois. “Sinny” for “cinema.” “Viddy” for “see,” “horrorshow” for “good” — from the Russian, khorosho, which gives you some idea of which political system has prevailed. The words locate him in a world of corrupted values, violence and boundless infantile indulgence. (His drug is “milk plus.”) When Alex is apprehended by the authorities and subjected to psychological conditioning to make him nauseated at any impulse towards violence, Burgess’s book becomes a meditation on whether a world in which evil can be freely chosen might still be preferable to one in which goodness is compelled. Stanley Kubrick’s coldly magnificent “sinny” adaptation has sometimes threatened to overshadow this great novel. Don’t let it happen.
