"War is peace, freedom is slavery, ignorance is strength"
They are the Party slogans, and are written in big letters on the white pyramid of the Ministry of Truth.
"Who controls the past controls the future. Who controls the present controls the past."
The people controlling the present control everything and can ultimately change the past and, therefore; the future. Big brother controls the present. The slogan is an example of the Party's technique of using false history to deteriorate the psychological independence of its people.
