Winston realizes that the proles constitute 85% of the population in Oceania. He notes in his dairy that “the proles, if they could somehow become conscious of their own strength, would have no need to conspire. They needed only to rise up and shake themselves like a horse shaking off flies. If they chose they could blow the Party to pieces tomorrow morning. Surely sooner or later it must occur to them to do it? And yet— —!”
In another entry in his diary, Winston writes: “Until [the proles] become conscious they will never rebel, and until after they have rebelled they cannot become conscious.”
But the proles do not become conscious of their own strength—Winston is unable to awaken them. The proles do not rebel and the Party continues to be in power in Oceania.
