2+2=5

The lyrics of this song convey that the truth is unimportant and intangible when the people in authority control all of the information. The song talks about all of these things being 'true' just because we are told that it is so, its our fault for not paying attention. The music was upbeat and penetrating which made the message seem more dire. In 1984 they said that if The Party told you that 2+2=5 then it does. Because regardless of what is actually fact, the 'truth' becomes whatever is commonly accepted.
