ПОМОГИТЕ С ПЕРЕВОДО THE SOCIETY OF STRANGERS. A society like ours is one of great interdependence. All of us are in the same boat, in many ways. Imagine, at one extreme, a pioneer family in the nineteenth century a family, let us say, that lived miles away from its nearest neighbor, that built its own house, grew its own food, wove its own clothing. The parents taught the children themselves, provided theirown entertainment, acted astheir own doctors, dentists barbers, nurses did everything, took every role. This is an extreme case, and was rare even in the past. But it points up how different our way of life really is. America in the 1980s is a far cry from the world of these pioneers. It is a far cry, too, from the way of life of tribal society, where custom rules, where life is bound to a tiny village and a few miles of woods all about it. Village life is life lived wholly in the so-called primary group, a face-to-face culture. Each man, woman, and child is related by blood or marriage or clan to everybody who matters tothat person. Similarly,on the island ofTristan da Cunha, the primary group was the only group. Inoursociety, however, though we are as profoundly dependent on each other as the people in any tribal culture, most of the links in our chain of dependence are strangers, not kinfolk or friends We are, in short, a"nation of strangers, a country where the greatest number potential abuses occurs between people who are strangers to each other". We work for big companies. We buy ready-made food and clothing. Strangers protect us, as police, or threaten us, as criminals
