While Winston is reading chapter 1 of Goldstein's book, he stops for a minute. Examine why he would stop.
As Winston is reading Goldstein's book, he realizes the importance of both the act and the work he is absorbing. Winston recognizes the gravity of what he is reading and also understands that the act itself carries defiance. It is at this moment that Winston has to pause in acknowledging the resistance he is exhibiting in both his act of reading and choice of what he is reading. This is not lost on Winston in his pause while he reads:
Winston stopped reading, chiefly in order to appreciate the fact that he was reading, in comfort and safety. He was alone: no telescreen, no ear at the keyhole, no nervous impulse to glance over his shoulder or cover the page with his hand. The sweet summer air played against his cheek.
Winston has to pause to appreciate the intense urgency of the moment. He pauses in his reading because he is reading away from the prying eyes of Big Brother. The work he is reading flies in the face of the Party and the Status Quo of control and repression that is intrinsic to Oceania. It is for this reason that he pauses. In this pause, Winston recognizes that he is completely alone, immersed in a condition of freedom. Seeing how this is so absent in Oceania, Winston pauses to appreciate it and to revel in it. Orwell captures the metaphysical experience of reading, something that Winston has to absorb not only in the act of reading but in the sense of touch that accompanies it. In touching the page and experiencing the moment, Winston pauses to immerse himself in an experience that many in Oceania are denied and an experience that those in the position of power wish to suppress from the body politic.
