The truthfulness of 'The Theory and Practice of Oligarchical Collectivism' is in doubt largely because of uncertainty about its authorship, and, as we have seen, a nearly identical ambiguity surrounds the Appendix. The parallel is significant. Two psychologically oriented critics, Murray Sperber and J. Brooks Bouson, have each pointed out strong resemblances between O'Brien's manipulation of Winston and Orwell's manipulation of the reader. I believe these resemblances extend to the book's handling of its two principal documents. Just as O'Brien plays upon Winston's desire for certain knowledge about Oceania's social and political structure, leading him on with the possibly spurious 'Goldstein' tract, so the story's narrator draws the truth-seeking reader into an Appendix whose truth value cannot be determined.
