How does the party control the past and how is the reality control an example of double think in jurman?

In George Orwell's "1984," the Party controls the past by constantly revising historical records and altering facts to fit its narrative, ensuring that they always appear infallible. This manipulation creates a reality where citizens accept contradictory beliefs—such as the Party being omnipotent while also being capable of error—illustrating the concept of doublethink. By instilling this cognitive dissonance, the Party maintains power over people's perceptions, effectively erasing any objective truth. This control over reality ensures that loyalty to the Party remains unchallenged, as individuals are conditioned to accept whatever version of the truth is presented to them.
