"... [T]he ministry of Truth, which concerned itself with news . . . The Ministry of Peace, which concerned itself with the war . . . The Ministry of Love, which concerned itself with law and order; and the Ministry of Plenty, which was responsible for economic affairs." (pg. 4)
In the 1984 universe, the Ministries that govern Oceania have names that are the opposite of what they are-- the Ministry of Love is the harshest ministry and deals with torture and punishment, nothing like love; the Ministry of Truth constantly rewrites the real truth and lies continuously about what's going on the in the real world. Orwell's naming the ministries after the opposite of what they stand for makes a statement about the world he has created. There is no real truth in Oceania because nothing is what it seems or is supposed to be.
