"The woman down there had no mind, she had only strong arms, a warm heart, and a fertile belly. He wondered how many children she had given birth to. It might easily be fifteen. She had had her momentary flowering, a year, perhaps, of wildrose beauty, and then she had suddenly swollen like a fertilized fruit and gone hard and red and coarse, and then her life had been laundering, scrubbing, darning, cooking, sweeping, polishing, mending, scrubbing, laundering, first for children, then for grandchildren, over thirty unbroken years. At the end of it she was still singing. The mystical reverence that he felt for her was somehow mixed up with the aspect of the pale, cloudless sky, stretching away behind the chimney pots into interminable distances. It was curious to think that the sky was the same for everybody, in Eurasia or Eastasia as well as here. And the people under the sky were also very much the same — everywhere, all over the world, hundreds or thousands of millions of people just like this, people ignorant of one another's existence, held apart by walls of hatred and lies, and yet almost exactly the same — people who had never learned to think but were storing up in their hearts and bellies and muscles the power that would one day overturn the world. If there was hope, it lay in the proles! [...] The future belonged to the proles. And could he be sure that when their time came, the world they constructed would not be just as alien to him, Winston Smith, as the world of the Party? Yes, because at least it would be a world of sanity. Where there is equality there can be sanity. Sooner or later it would happen: strength would change into consciousness. The proles were immortal; you could not doubt it when you looked at that valiant figure in the yard. In the end their awakening would come. And until that happened, though it might be a thousand years, they would stay alive against all the odds, like the birds, passing on from body to body the vitality which the Party did not share and could not kill. [...] The birds sang, the proles sang, the Party did not sing. All round the world, in London and New York, in Africa and Brazil and in the mysterious, forbidden lands beyond the frontiers, in the streets of Paris and Berlin, in the villages of the endless Russian plain, in the bazaars of China and Japan — everywhere stood the same unconquerable figure, made monstrous by work and childbearing, toiling from birth to death and still singing. Out of those mighty loins a race of conscious beings must one day come. You were the dead; theirs was the future. But you could share in that future if you kept alive the mind as they kept alive the body, and passed on the secret doctrine that two plus two make four."
