you will cry out with pain

'That was forty,' said O'Brien. 'You can see that the numbers on this dial run up to a hundred. Will you please remember, throughout our conversation, that I have it in my power to inflict pain on you at any moment and to whatever degree I choose? If you tell me any lies, or attempt to prevaricate in any way, or even fall below your usual level of intelligence, you will cry out with pain, instantly. Do you understand that?' 'Yes,' said Winston. O'Brien's manner became less severe. He resettled his spectacles thoughtfully, and took a pace or two up and down. When he spoke his voice was gentle and patient. He had the air of a doctor, a teacher, even a priest, anxious to explain and persuade rather than to punish. 'I am taking trouble with you, Winston,' he said, 'because you are worth trouble. You know perfectly well what is the matter with you. You have known it for years, though you have fought against the knowledge. You are mentally deranged. You suffer from a defective memory. You are unable to remember real events and you persuade yourself that you remember other events which never happened. Fortunately it is curable. You have never cured yourself of it, because you did not choose to. There was a small effort of the will that you were not ready to make. Even now, I am well aware, you are clinging to your disease under the impression that it is a virtue. Now we will take an example. At this moment, which power is Oceania at war with?' 'When I was arrested, Oceania was at war with Eastasia.' 'With Eastasia. Good. And Oceania has always been at war with Eastasia, has it not?' Winston drew in his breath. He opened his mouth to speak and then did not speak. He could not take his eyes away from the dial. 'The truth, please, Winston. Your truth. Tell me what you think you remember.' 'I remember that until only a week before I was arrested, we were not at war with Eastasia at all. We were in alliance with them. The war was against Eurasia. That had lasted for four years. Before that --' O'Brien stopped him with a movement of the hand. 'Another example,' he said. 'Some years ago you had a very serious delusion indeed. You believed that three men, three onetime Party members named Jones, Aaronson, and Rutherford men who were executed for treachery and sabotage after making the fullest possible confession -- were not guilty of the crimes they were charged with. You believed that you had seen unmistakable documentary evidence proving that their confessions were false. There was a certain photograph about which you had a hallucination. You believed that you had actually held it in your hands. It was a photograph something like this.'
