Winston Smith - The novel's protagonist makes an unlikely rebel. He works in the ministry of truth as a minor party member. He is guilty of thoughtcrime, manifested through the purchase of a diary, writing "DOWN WITH BIG BROTHER", and having a romantic encounter. As with all criminals, he is caught and confesses.
Analysis: Winston is weak and sick as the novel begins. He constantly drinks gin and secretly harbors ill will toward Big Brother and the party. He desires more than anything to have a real love affair. Winston's most dominant attribute is fatalism, the belief that everything will end up bad (kind of like being a Cleveland sports fan). His fatalism causes him to test the limits of rebelliousness and eventually displays just how powerful the party is.
Julia - Winston's lover sends him a secret note proclaiming her love for him. The two meet in the countryside at a location discovered while Julia participated in Junior Anti-Sex League community hikes. Whereas Winston seeks to destroy the party and overthrow the government, Julia desires only to break enough rules to have fun.
Analysis: Winston calls Julia a "rebel only from the waist down," a polite way of calling her immoral. Of course, by calling her that name, he is giving her a compliment. Other than a desire for intercourse and their hatred for the party, the two have very little in common.
