It is he thinks 1984. Oceania and the two other world superstates, Eurasia and Eastasia, are involved in a continuous war over the remaining world, and constantly shift alliances. As the novel progresses, it becomes clear that the war is largely an illusion, and that the three superstates maintain this illusion for their mutual benefit. It serves their shared purpose of holding onto absolute power over their respective peoples. Much of the warfare, in fact, is inflicted by these governments upon their own citizens.
Oceanic society is hierarchical and oligarchic.
Above the proles is the Outer Party, less privileged members of the Party who spend their time keeping the wheels of the Party machine well-oiled and running smoothly. Above the Outer Party are the Inner Party members, who enjoy the fruits of power and production, and whose sole aim is to perpetuate power for the Party, forever. On this April day, Winston has left the Ministry of Truth, where he works in the Records Department, to take his lunch break at home, because he wishes to write in his diary a compromising activity and a compromising possession to begin with. Yet, despite his fears, he is overwhelmed with the need to impose some sanity upon his world. Winston is a rebel at heart, a heretic who does not subscribe to Party doctrines or beliefs.
