Brilliant. George Orwell is a genius for two definite reasons: depth of his imagination and ability to projection it. The book is vivid portrayal of a totalitarian society. A reflection of life where thinking is eliminated; stability in society is achieved through total control of actions and induced thoughts. It is amazing how Orwell uses language to symbolize ideas. One can get a peek at it from his description of Newspeak.
Sadly, the book ends not in the conventional victory of the soul, but in a resignation to the forceful control. I heard his other book Animal Farm, also ends in a tragedy. Makes me wonder if Orwell was a bloody pesimisst. Or does he simply want to send an intense warning.
