Once, the trees from which the wood came, the fields from which grain came, the springs, river, well, or rain from which drinking water came would have been familiar; every object would appear out of somewhere, from someone or something known to the user, and the producers and consumers would be the same people or people who knew one another. Industrialisation, urbanisation, and transnational markets created a world where water poured out of faucets, food and clothing appeared in stores, fuel ( in our time if not in Orwell's with the coal chutes and sooty air) was largely invisible, and the work that held all this together was often done by people who were themselves invisible. There were undeniable benefits - a more stimulating and various mental life - but they came at a cost.
The places, plants, animals, materials, and objects that had once been as well known as friends and family had become strangers, as had the people who worked with these materials. Things appeared from beyond the horizon, from beyond knowing, and knowing was an act of volition instead of part of everyday life.
