How could you make appeal to the future when not a trace of you, not even an anonymous word scribbled on a piece of paper, could physically survive? - George Orwell

The smell of her hair, the taste of her mouth, the feeling of her skin seemed to have got inside him, or into the air all round him. She had become a physical necessity.

If there was hope, it must lie in the proles, because only there, in those swarming disregarded masses, eighty-five percent of the population of Oceania, could the force to destroy the Party ever be generated. The Party could not be overthrown from within. Its enemies, if it had any enemies, had no way of coming together or even of identifying one another. Even if the legendary Brotherhood existed, as just possibly it might, it was inconceivable that its members could ever assemble in larger numbers than twos and threes. Rebellion meant a look in the eyes, an inflection of the voice; at the most, an occasional whispered word. But the proles, if only they could somehow become conscious of their own strength, would have no need to conspire. They need only to rise up and shake themselves like a horse shaking off flies. If they chose they could blow the Party to pieces tomorrow morning. Surely sooner or later it must occur to them to do it.

Anyone who knows of a provable instance of colour discrimination ought always to expose it.
