Winston loathed this exercise, which sent shooting pains all the way from his heels to his buttocks and often ended by bringing on another coughing fit. The half-pleasant quality went out of his meditations. The past, he reflected, had not merely been altered, it had been actually destroyed. For how could you establish even the most obvious fact when there existed no record outside your own memory? He tried to remember in what year he had first heard mention of Big Brother.
