In 1984, what type of propaganda techniques are used in the inscription on the white pyramid at the Ministry of Truth?

Written
on the side of the massive white pyramid of the Ministry of Truth is the Party's
slogan:

War is peace

Freedom is slavery

Ignorance is
strength

These paradoxical statements
introduce the reader to the Party's concept of doublethink, which is the technique of
simultaneously believing two contradictory statements at the same time. In an attempt to control
every aspect of society, the Party developed the technique of doublethink in order to eliminate
the citizens' ability to process information logically and to influence the population into
accepting every government policy and statement without question.

The phrases
of the Party's motto are also considered paradoxical and inconspicuously ring true. Through
constant conflict, the Party maintains a heightened level of hysteria at all times, consumes
valuable resources that could be used to improve the standard of living, and sends citizens to
die in battle. Continual warfare essentially uses fear to manipulate the citizens into following
government policies. The citizens only look to Big Brother for protection, which strengthens
their loyalty, resulting in a controllable populace. Through the technique of doublethink, the
Party manipulates the citizens of Oceania into associating freedom with slavery, which further
confuses the population, making them easier to control and manipulate. The third phrase of the
Party's motto also rings true. The citizens' ignorance is essentially Big Brother's strength.
The ignorant, uninformed citizens passively accept Big Brother's agenda and continue to live
oppressed lives without ever challenging the government's authority.
