stupidity. But stupidity is not enough. On the contrary, orthodoxy in the full sense demands a control over one's own mental processes as complete as that of a contortionist over his body. Oceanic society rests ultimately on the belief that Big Brother is omnipotent and that the Party is infallible. But since in reality Big Brother is not omnipotent and the party is not infallible, there is need for an unwearying, moment-to-moment flexibility in the treatment of facts. The keyword here is blackwhite. Like so many Newspeak words, this word has two mutually contradictory meanings. Applied to an opponent, it means the habit of impudently claiming that black is white, in contradiction of the plain facts. Applied to a Party member, it means a loyal willingness to say that black is white when Party discipline demands this. But it means also the ability to believe that black is white, and more, to know that black is white, and to forget that one has ever believed the contrary. This demands a continuous alteration of the past, made possible by the system of thought which really embraces all the rest, and which is known in Newspeak as doublethink.

The alteration of the past is necessary for two reasons, one of which is subsidiary and, so to speak, precautionary. The subsidiary reason is that the Party member, like the proletarian, tolerates present-day conditions partly because he has no standards of comparison. He must be cut off from the past, just as he must be cut off from foreign countries, because it is necessary for him to believe that he is better off than his ancestors and that the average level of material comfort is constantly rising. But by far the more important reason for the readjustment of the past is the need to safeguard the infallibility of the Party. It is not merely that speeches, statistics, and records of every kind must be constantly brought up to date in order to show that the predictions of the Party were in all cases right. It is also that no change in doctrine or in political alignment can ever be admitted. For to change one's mind, or even one's policy, is a confession of weakness. If, for example, Eurasia or Eastasia (whichever it may be) is the enemy today, then that country must always have been the enemy. And if the facts say otherwise then the facts must be altered. Thus history is continuously rewritten. This day-to-day falsification of the past, carried out by the Ministry of Truth, is as necessary to the stability of the regime as the work of repression and espionage carried out by the Ministry of Love.

The mutability of the past is the central tenet of Ingsoc. Past events, it is argued, have no objective existence, but survive only in written records and in human memories. The past is whatever the records and the memories agree upon. And since the Party is in full control of all records and in equally full control of the minds of its members, it follows that the past is whatever the Party chooses to make it. It also follows that though the past is alterable, it never has been altered in any specific instance. For when it has been recreated in whatever shape is needed at the moment, then this new version is the past, and no different past can ever have existed. This holds good even when, as often happens, the same event has to be altered out of recognition several times in the course of a year. At all times the Party is in possession of absolute truth, and clearly the absolute can never have been different from what it is now. It will be seen that the control of the past depends above all on the training of memory. To make sure
