Winston had heard the mid-day bulletin which had not mentioned any definite area attacked by Eurasia. He was rather concerned, mentally considering which areas were in jeopardy.
As Winston saw it, losing Central Africa: for the first time in the whole war, the territory of Oceania itself was menaced.
A violent emotion, not fear but undifferentiated excitement, flared up in him, then faded.
He stopped thinking about the war.
He now had the inability tor fix his mind on any one subject for more than a few moments at a time. He picked up his glass and drained it at a gulp.
This ‘violent emotion’ is obviously the result of the torture. The torture which was to destroy his mind. To make him ‘police’ his own thoughts. The torture which made him unable to concentrate, to meditate, to analyse or reflect.
