But when war becomes literally continuous, it also ceases to be dangerous. When war is continuous there is no such thing as military necessity. Technical progress can cease and the most palpable facts can be denied or disregarded. As we have seen, researches that could be called scientific are still carried out for the purposes of war, but they are essentially a kind of daydreaming, and their failure to show results is not important. Efficiency, even military efficiency, is no longer needed. Nothing is efficient in Oceania except the Thought Police. Since each of the three superstates is unconquerable, each is in effect a separate universe within which almost any perversion of thought can be safely practised. Reality only exerts its pressure through the needs of everyday life—the need to eat and drink, to get shelter and clothing, to avoid swallowing poison or stepping out of top- storey windows, and the like. Between life and death, and between physical pleasure and physical pain, there is still a distinction, but that is all. Cut off from contact with the outer world, and with the past, the citizen of Oceania is like a man in interstellar space, who has no way of knowing which direction is up and which is down. The rulers of such a state are absolute, as the Pharaohs or the Caesars could not be. They are obliged to prevent their followers from starving to death in numbers large enough to be inconvenient, and they are obliged to remain at the same low level of military technique as their rivals; but once that minimum is achieved, they can twist reality into whatever shape they choose.
