Two plus two make five

The phrase "two plus two make five" (or "2 + 2 = 5") is sometimes used as a succinct and vivid representation of an illogical statement, especially one made and maintained to suit an ideological agenda. Its common use originates from its inclusion in the novel Nineteen Eighty-Four by George Orwell (Part Three, Chapter Two), where it is contrasted with the true, scientific phrase "two plus two make four."
