Warning: I've only read it three times. It might not be accurate.I'd suggest reading up on why and when Orwell wrote this. (If I have my dates right, this book was written after World War II). Comparing fiction to facts might help. Try contrasting the story to Hitler and the Nazi. Big Brother was omnipresent and misled people just like many other dictators did; and the Youth League and the Junior Anti Sex League resembles the Hitler Youth in which they were both encouraged to denounce parents. The presence of the leagues, serves to exterminate natural affections and love. Get some background on the Russian Revolutions as well.
I know you've read Animal Farm, which was a satire on communist ideals. That tells us that Orwell was pretty much appalled with communism and stronger state control. So if you can just see where the writer is coming from while writing this, you'll understand it so much better. Nineteen Eighty-four focuses on a cruel totalitarian regime, the unfathomable control of reality, lone rebellion, production of lies, extent of trust and loyalty, political control and betrayal, etc. When you get more familiar with Orwell's background, you'll know that he based the majority of the book's themes around his own concerns and personal experiences.
Anyway a quick run through...
Winston Smith
-Minor member of the Outer Party
-Works in the Ministry of Truth
-Fucking ugly(from the descriptions of him, lol)
His job is to falsify records and official documents (even the news) so that the Party's preferred version of the past can be seen as "the truth". Society only receives the information which the Party authorises. From his work, Winston is disturbed by the knowledge that a real history exists. He has knowledge of the genuine past and he actually prefers it to the ones he is employed to make up. He's depressed by the total obedience given to lies by others around him, but effortlessly isolates his outer emotions to avoid extreme consequences. His world is oppressed by tyranny. Any signs of rebellion would probably get him convicted (to death), as his government disallows any signs of opposition. The Party’s surveillance is everywhere, through the telescreens. "Big brother is watching you".
He keeps a secret diary of his thoughts. This is the first sign of Winston's rebellion. He speculates whether the "proles" or "lower-class people" might one day overthrow the party. It turns out that he comes to value the life of the proles, but can not have any sort of relationship/friendship with them. Think: Dull, android, mediocre world. He yearns for a life outside government control; freedom.
In Winston's world, four departments run the country: Ministry of Truth, Peace, Plenty and Love.
Peace: In charge of the "war*" that is going on. A never-ending war.
Love: Terror enforcement
Plenty: (quote from insight) deliberately makes the people endure ‘a chronic shortage of half the necessities of life’ (page 199).
Truth:
Propaganda, fraud
*after many years of war with Eurasia, Oceania(Winston's place) goes to war against Eastasia, taking Eurasia for its ally. The enemy constantly changes and there's a reason for this. The never ending war is made up to keep order in the people. It declines prosperity, keeps the people ignorant and creates a sense of enmity between everyone and the always changing foe. Without the luxuries, the people would have no chance of an uprising; no chance of overthrowing the Party. (The proles make up the majority of the population. I think it was 85%?). The Government continues to distract the proles by introducing incentives such as gambling.
As with the above, Winston's job is to rewrite records of the past to make them conform to the official version of events. So the employees of the Ministry of Truth had to ensure that the issues associated with the war meet the recent version of history which satisfies the Party's requirements.
Julia
-no last name mentioned
-works in the fiction department (Pornosec). Produces pornography foor young proles.
Winston suspects her of being a spy. There is also a possibility of her being a member of the Thought Police. You could argue whether the relationship between Julia and Winston was authentic or not.
... Okay. CBF now. Sleep. I'll add more later. No one quote anything from this post, it might change.
Side note: If you liked this book, I'd also recommend you read Brave New World by Aldous Huxley.
