Salinger's Message Still Apposite

The death of J D Salinger (for some reason nobody calls him Jerome) on 27th January prompted me to read his one famous book, "The Catcher in the Rye," again. This book "had the dubious distinction of being at once the most frequently censored book across the nation and the second-most frequently taught novel in public high schools" (Yardley, Jonathan (2004-10-19). "J.D. Salinger's Holden Caulfield, Aging Gracelessly". The Washington Post. Retrieved 2007-04-13.)
Holden Caulfield, 17, has been expelled from prestigious Pencey Prep and it is not the first time he has been expelled from a school. Action takes place over 48 hours starting when he decides to leave early, not wishing to face up to his parents' inevitable rebukes. He travels to New York and checks into a hotel, near where he lives. His experiences, include contact with old girl friends, an encounter with a prostitute (he is unable to follow this through) and the rescuing hand of his younger sister Phoebe.
The language, uniquely for its time, is that of the disaffected youth, struggling to make sense of the world; alienated, defensive, cynical, immoral. Holden, in a touching conversation with his sister (chapter 22) confesses that all he wants to do is "catch everybody if they start to go over the cliff." "I keep picturing all these little kids playing some game in this big field of rye and all."
With authentic turn of phrase, no censorship of profanities, his opinions, presented in a stream of consciousness, are cutting, shocking and depressing. When you realise that this young man, with life's big puzzle yet to be solved, is simply telling you how it is for him, the world turns upside down, and you question the sanity of our culture and morals; the pretensions of the modern world; the expectations we try to live up to and mostly fail. Who is it who is having the nervous breakdown here. Is Holden's treatment by "the one psychoanalyst guy" helping him or breaking him in.
