Orwell then goes on to discuss the difficulty of translating the work of the past into Newspeak. He uses as an example the Declaration of Independence: “ All mans are equal was a possible Newspeak sentence," but only in that "it expressed a palpable untruth---. that all men are of equal size, weight, or strength.” As for the rest of Thomas Jefferson’s rousing preamble, “it would have been quite impossible to render this into Newspeak,” writes Orwell. “The nearest one could come to doing so would be to swallow the whole passage up in the single word crimethink .”
In his edition of the Collected Works (20 volumes), Peter Davison notes that Orwell's American publisher claimed that the title derived from reversing the date, 1948, though there's no documentary evidence for this. Davison also argues that the date 1984 is linked to the year of Richard Blair's birth, 1944, and notes that in the manuscript of the novel, the narrative occurs, successively, in 1980, 1982 and finally, 1984. There's no mystery about the decision to abandon "The Last Man in Europe". Orwell himself was always unsure of it. It was his publisher, Fred Warburg who suggested that Nineteen Eighty-Four was a more commercial title.
