"Barbie," a twelve-inch plastic teen-ager, is the best-known and best-selling doll in history. Since its introduction in 1959, the Barbie doll population of the world has grown to 12,000,000 – more than the human population of Los Angeles or London or Paris. Little girls adore Barbie because she is highly realistic and eminently dress-upable. Mattel, Inc., makers of Barbie, also sells a complete wardrobe for her, including clothes for ordinary daytime wear, clothes for formal party wear, clothes for swimming and skiing.

Recently Mattel announced a new improved Barbie doll. The new version has a slimmer figure, "real" eyelashes, and a twist-and-turn waist that makes her more humanoid than ever. Moreover, Mattel announced that, for the first time, any young lady wishing to purchase a new Barbie would receive a trade-in allowance for her old one.

What Mattel did not announce was that by trading in her old doll for a technologically improved model, the little girl of today, citizen of tomorrow's super-industrial world, would learn a fundamental lesson about the new society: that man's relationships with things are increasingly temporary.

The ocean of man-made physical objects that surrounds us is set within a larger ocean of natural objects. But increasingly, it is the technologically produced environment that matters for the individual. The texture of plastic or concrete, the iridescent glisten of an automobile under a streetlight, the staggering vision of a cityscape seen from the window of a jet – these are the intimate realities of his existence. Man-made things enter into and color his consciousness. Their number is expanding with explosive force, both absolutely and relative to the natural environment. This will be even more true in super-industrial society than it is today.

Anti-materialists tend to deride the importance of "things." Yet things are highly significant, not merely because of their functional utility, but also because of their psychological impact. We develop relationships with things. Things affect our sense of continuity or discontinuity. They play a role in the structure of situations and the foreshortening of our relationships with things accelerates the pace of life.

Moreover, our attitudes toward things reflect basic value judgments. Nothing could be more dramatic than the difference between the new breed of little girls who cheerfully turn in their Barbies for the new improved model and those who, like their mothers and grandmothers before them, clutch lingeringly and lovingly to the same doll until it disintegrates from sheer age. In this difference lies the contrast between past and future, between societies based on permanence, and the new, fast-forming society based on transience.

That man-thing relationships are growing more and more temporary may be illustrated by examining the culture surrounding the little girl who trades in her doll. This child soon learns that Barbie dolls are by no means the only physical objects that pass into and out of her young life at a rapid clip. Diapers, bibs, paper napkins, Kleenex, towels, non-returnable soda bottles – all are used up quickly in her home and ruthlessly eliminated. Corn muffins come in baking tins that are thrown away after one use. Spinach is encased in plastic sacks that can be dropped into a pan of boiling water for heating, and then thrown away. TV dinners are cooked and often served on throw-away trays. Her home is a large processing machine through which objects flow, entering and leaving, at a faster and faster rate of speed. From birth on, she is inextricably embedded in a throw-away culture.

The idea of using a product once or for a brief period and then replacing it, runs counter to the grain of societies or individuals steeped in a heritage of poverty. Not long ago Uriel Rone, a market researcher for the French advertising agency Publicis, told me: "The French housewife is not used to disposable products. She likes to keep things, even old things, rather than throw them away. We represented one company that wanted to introduce a kind of plastic throw-away curtain. We did a marketing study for them and found the resistance too strong." This resistance, however, is dying all over the developed world.

Thus a writer, Edward Maze, has pointed out that many Americans visiting Sweden in the early 1950's were astounded by its cleanliness. "We were almost awed by the fact that there were no beer and soft drink bottles by the roadsides, as, much to our shame, there were in America. But by the 1960's, lo and behold, bottles were suddenly blooming along Swedish highways ... What happened? Sweden had become a buy, use and throw-away society, following the American pattern." In Japan today throw-away tissues are so universal that cloth handkerchiefs are regarded as old fashioned, not to say unsanitary. In England for sixpence one may buy a "Dentamatic throw-away toothbrush" which comes already coated with toothpaste for its one-time use. And even in France, disposable cigarette lighters are commonplace. From cardboard milk containers to the rockets that power space vehicles, products created for short-term or one-time use are becoming more numerous and crucial to our way of life.

The recent introduction of paper and quasi-paper clothing carried the trend toward disposability a step further. Fashionable boutiques and working-class clothing stores have sprouted whole departments devoted to gaily colored and imaginatively designed paper apparel. Fashion magazines display breathtakingly sumptuous gowns, coats, pajamas, even wedding dresses made of paper. The bride pictured in one of these wears a long white train of lace-like paper that, the caption writer notes, will make "great kitchen curtains" after the ceremony.

Paper clothes are particularly suitable for children. Writes one fashion expert: "Little girls will soon be able to spill ice cream, draw pictures and make cutouts on their clothes while their mothers smile benignly at their creativity." And for adults who want to express their own creativity, there is even a "paint-yourself-dress" complete with brushes. Price: $2.00.

Price, of course, is a critical factor behind the paper explosion. Thus a department store features simple A-line dresses made of what it calls "devil-may-care cellulose fiber and nylon." At $1.29 each, it is almost cheaper for the consumer to buy and discard a new one than to send an ordinary dress to the cleaners. Soon it will be. But more than economics is involved, for the extension of the throw-away culture has important psychological consequences.

We develop a throw-away mentality to match our throw-away products. This mentality produces, among other things, a set of radically altered values with respect to property. But the spread of disposability through the society also implies decreased durations in man-thing relationships. Instead of being linked with a single object over a relatively long span of time, we are linked for brief periods with the succession of objects that supplant it.

The shift toward transience is even manifest in architecture – precisely that part of the physical environment that in the past contributed mostly heavily to man's sense of permanence. The child who trades in her Barbie doll cannot but also recognize the transience of buildings and other large structures that surround her. We raze landmarks. We tear down whole streets and cities and put new ones up at a mind-numbing rate.

"The average age of dwellings has steadily declined," writes E. F. Carter of the Stanford Research Institute, "from being virtually infinite in the days of caves to ... approximately a hundred years for houses built in United States colonial days, to about forty years at present." And Michael Wood, an English writer comments: The American "... made his world yesterday, and he knows exactly how fragile, how shifting it is. Buildings in New York literally disappear overnight, and the face of a city can change completely in a year."
