Explain the significance of "two and two make five" using specific and detailed references to the text (1984 by George Orwell).

In
,has embodied all his fears about the destructive effects of a totalitarian
regime. In this novel, the Party writes and rewrites history (including the very existence of
its friends and enemies), and the face of the Party is Big Brother. In this worldhas created,
truth is relative, and Big Brother maintains power by controlling the minds of the people (a
term I use loosely here).

The national slogan of Oceana sets the tone for the
kind of deception and double-dealing (known as "double-speak) Big Brother does with
language: 

War is Peace

Freedom is
Slavery

Ignorance is Strength

Obviously, in the world of Big Brother, truth is relative; more importantly, the
ability to make people accept a lie as truth is the mark of true control. Early in the
novel,asserts this truth: Freedom is the freedom to say that two plus two make four. If that
is granted, all else follows. 

Winston already knows that Big Brother is
powerful enough to control the past and the future (physical realities), but he had hoped that
it would not be able to exert the same kind of control over the mind--until he reads
this:

In the end the Party would announce that two and two
made five, and you would have to believe it. It was inevitable that they should make that claim
sooner or later: the logic of their position demanded it. Not merely the validity of experience,
but the very existence of external reality was tacitly denied by their philosophy.

Winston does not conform like the others, and he is constantly
exploring the relationship between the mind and reality. If reality exists only in the mind and
the Party controls the mind, there is no hope at all, for then the Party controls
everything.

Winston thinks, For, after all, how do we
know that two and two make four? Or that the force of gravity works? Or that the past is
unchangeable? If both the past and the external world exist only in the mind, and if the mind
itself is controllablewhat then?

When Winston is finally
caught and taken to the Ministry of Love, he is tortured until he finally screams that 2 + 2 = 5
and the Party deems him fit to be released back into society. In the last chapter of the novel,
Winston is sitting at a table in the bar where he used to play chess. He writes the faulty
equation in the dust on the table and drops the white knight onto the board in a kind of
defeat. 

If the Party can control the mind, it can control reality. This
slogan (and the true equation, 2 + 2 = 4) is representative of the Party's ability to control
the mind. it is a motif that begins early in the novel and is seen consistently until the
end.
