At this moment the entire group of people broke into a deep, slow, rhythmical chant of ‘B-B!... B-B!... B-B!’ – over and over again, very slowly, with a long pause between the first ‘B’ and the second – a heavy, murmurous sound, somehow curiously savage, in the background of which one seemed to hear the stamp of naked feet and the throbbing of tom-toms. For perhaps as much as thirty seconds they kept it up. It was a refrain that was often heard in moments of overwhelming emotion. Partly it was a sort of hymn to the wisdom and majesty of Big Brother, but still more it was an act of self-hypnosis, a deliberate drowning of consciousness by means of rhythmic noise. Winston’s entrails seemed to grow cold. In the Two Minutes Hate he could not help sharing in the general delirium, but this subhuman chanting of ‘B-B!... B-B!’ always filled him with horror. Of course he chanted with the rest: it was impossible to do otherwise. To dissemble your feelings, to control your face, to do what everyone else was doing, was an instinctive reaction. But there was a space of a couple of seconds during which the expression in his eyes might conceivably have betrayed him. And it was exactly at this moment that the significant thing happened – if, indeed, it did happen.
