1984 by George Orwell, Passage 2 (page 208-209)

     "‘Do you know where you are, Winston?’ he said.
‘I don’t know. I can guess. In the Ministry of Love.’
‘Do you know how long you have been here?’
‘I don’t know. Days, weeks, months — I think it is months.’
‘And why do you imagine that we bring people to this place?’
‘To make them confess.’
‘No, that is not the reason. Try again.’
‘To punish them.’
‘No!’ exclaimed O’Brien. His voice had changed extraordinarily, and his face had suddenly become both stern and animated. ‘No! Not merely to extract your confession, not to punish you. Shall I tell you why we have brought you here? To cure you! To make you sane! Will you understand, Winston, that no one whom we bring to this place ever leaves our hands uncured? We are not interested in those stupid crimes that you have committed. The Party is not interested in the overt act: the thought is all we care about. We do not merely destroy our enemies, we change them. Do you understand what I mean by that?’"

     This passage is a dialogue between Winston and O'Brien, who has been torturing Winston. O'Brien is explaining to Winston that the torture is not simply punishment, or to make Winston say anything, but to change Winston completely. The object is to make him into a new person with a new mindset. To change everything he believes in a way that he will truly want to be loyal to the government. Orwell shows that the torture has been long and that it has been messing with Winston's mind by saying that Winston doesn't know the difference between days and months while he is at the Ministry of Love. Additionally, O'Brien believes that this is good and right. He shows this by using words like "cure,: "change," and "we care." O'Brien is trying to slowly convince Winston that he is wrong, and O'Brien is right.
