Controlling the past

'There is a Party slogan dealing with the control of the past,' he said. 'Repeat it, if you please.' '"Who controls the past controls the future: who controls the present controls the past,"' repeated Winston obediently.

'You are no metaphysician, Winston,' he said. 'Until this moment you had never considered what is meant by existence. I will put it more precisely. Does the past exist concretely, in space? Is there somewhere or other a place, a world of solid objects, where the past is still happening?' 'No.' 'Then where does the past exist, if at all?' 'In records. It is written down.' 'In records. And----?' 'In the mind. In human memories.' 'In memory. Very well, then. We, the Party, control all records, and we control all memories. Then we control the past, do we not?' 'But how can you stop people remembering things?' cried Winston again momentarily forgetting the dial. 'It is involuntary. It is outside oneself. How can you control memory? You have not controlled mine!' O'Brien's manner grew stern again. He laid his hand on the dial. 'On the contrary,' he said, 'YOU have not controlled it.
