In Oceania at the present day, Science, in the old sense, has almost ceased to exist. In Newspeak there is no word for 'Science.' The empirical method of thought, on which all the scientific achievements of the past were founded, is opposed to the most fundamental principles of Ingsoc.
George OrwellTo know and not to know, to be conscious of complete truthfulneยญss while telling carefully constructeยญd lies, to hold simultaneoยญusly two opinions which cancelled out, knowing them to be contradictยญory and believing in both of them, to use logic against logic, to repudiate morality while laying claim to it, to believe that democracy was impossible and that the Party was the guardian of democracy.
George OrwellWinston worked in the RECORDS DEPARTMENT (a single branch of the Ministry of Truth) editing and writing for The Times. He dictated into a machine called a Speakwrite. Winston would receive articles or news-items which for one reason or another it was thought necessary to alter, or, in Newspeak, rectify. If, for example, the Ministry of Plenty forecast a surplus, and in reality the result was grossly less, Winston's job was to change previous versions so the old version would agree with the new one.
