—Wislawa Szymborska (1923–2012), from "Under One Small Star"

Voluntary memory, the memory of the intellect and the eyes, [gives] us only imprecise facsimiles of the past which no more resemble it than pictures by bad painters resemble the spring…. So we don’t believe that life is beautiful because we don’t recall it, but if we get a whiff of a long-forgotten smell we are suddenly intoxicated, and similarly we think we no longer love the dead, because we don’t remember them, but if by chance we come across an old glove we burst into tears.

What if, instead of that playful word bubble, we tried something a bit more accurately descriptive when growth at any cost became the goal. Say, "tumor": "the dot-com tumor," "the subprime tumor," "the derivatives tumor."

Would anyone seriously gainsay the highest possible vigilance over the proper functioning of their own body or doubt the need for strong regulation? Who, facing the prospect of a tumorous outbreak or living with a body demonstrably prone to such outbreaks, would entrust that body to a band of physicians blithely committed to laissez faire regarding these fatal bubbles of flesh?

Words matter. Metaphors frame thought. Pay them heed and tend them well.

“Olympic National Park is the listener’s Yosemite,” Hempton said of his decision to locate his One Square Inch within the park’s forested realm. “In a single day, you can listen to an alpine environment, a wilderness beach, and a temperate rain forest. And it has the longest noise-free interval of any national park I’ve been to, and I’ve been to them all.”

Part of Olympic’s quiet stems from its location: It sits on a peninsula in a secluded corner of the country. The park is not crossed by highways, navigable rivers, or utility rights of way; and it lies west of the major cross-country plane routes. Only three commercial-airline paths encroach upon its borders. Alaska Airlines is the most active, flying overhead 37 times each day in summer, but it tries to avoid the park during routine maintenance and training flights—a concession the carrier made to Hempton after he wrote asking it to change its flight patterns.

Religions, he thinks, have the buttons and know how to use them. His book considers the Catholic mass, early Christianitiy's ritual of agape or love feasts, and Jewish Passover rituals to explore how religions encouraged us to overcome fear of strangers and create communities. He then tentatively imagines a so-called "agape restaurant" where, instead of dining with like-minded friends, you would be invited to eat with strangers. It would be the antithesis of Facebook.

Starting in 2000, a program in Mexico’s Coahuila state called “Piso Firme” (Firm Floor) offered up to $150 per home in mixed concrete, delivered directly to families who used it to cover their dirt floors. Scholar Paul Gertler evaluated the impact: Kids in houses that moved from all-dirt to all-concrete floors saw parasitic infestation rates drop 78 percent; the number of children who had diarrhea in any given month dropped by half; anemia fell more than four-fifths; and scores on cognitive tests went up by more than a third. (Perhaps unsurprisingly, mothers in newly cemented houses reported less depression and greater life satisfaction.) By 2005, Piso Firme had spread to other states, and 300,000 households—about 10 percent of dirt-floor houses in Mexico—had taken part in the program.

It helps if the street outside the house gets paved, too—not so much for health reasons as for economic ones. Economists Marco Gonzalez-Navarro and Climent Quintana-Domeque found in a 2010 study that paving the street in the town of Acayucan, Mexico, added more than 50 percent to land values and caused a 31 percent rise in rental values. It also considerably increased households’ access to credit. As a result, households on paved streets were 40 percent more likely to have cars.

Like so many of the topics we cover, bicycles are less a single cultural artifact than a multitude of them—from the pink bike with tassels and streamers your little sister learned to ride when she was 4, to Lance Armstrong’s lean mean hill-climbing machine, an extension of the lean mean man himself. There are road bikes, mountain bikes, and (collapsible) subway bikes, fixies and freewheels, tandems and tagalongs.

In whatever form, though, bicycles are perhaps the most basic instance of transportation technology, imparting a surprising amount of freedom, speed, and delight while drawing on nothing more than the strength in our legs and the simple efficiency of wheels and gears. Ride a bike and you experience your own capacities extended; you also discover how much more power has been available, untapped, in the world than you might have imagined. The 4-year-old teetering and weaving down the road is discovering that beautiful perilous abundance, and the exhilaration of that moment means that chances are she’ll never forget, any more than you did, when she learned to ride.

What do bicycles make of the world?

[T]echnology is an enabler of rights, not a right itself. There is a high bar for something to be considered a human right. Loosely put, it must be among the things we as humans need in order to lead healthy, meaningful lives, like freedom from torture or freedom of conscience. It is a mistake to place any particular technology in this exalted category, since over time we will end up valuing the wrong things. For example, at one time if you didn’t have a horse it was hard to make a living. But the important right in that case was the right to make a living, not the right to a horse. Today, if I were granted a right to have a horse, I’m not sure where I would put it.

Old Jonathan Edwards wrote, “It has all along been God’s manner to open new scenes, and to bring forth to view things new and wonderful.” These scenes are the narrative method of the Bible, which assumes a steady march of history, the continuous unfolding of significant event, from the primordial quarrel of two brothers in a field to supper with a stranger at Emmaus. There is a cosmic irony in the veil of insignificance that obscures the new and wonderful. Moments of the highest import pass among people who are so marginal that conventional history would not have noticed them: aliens, the enslaved, people themselves utterly unaware that their lives would have consequence. The great assumption of literary realism is that ordinary lives are invested with a kind of significance that justifies, or requires, its endless iterations of the commonplace, including, of course, crimes and passions and defeats, however minor these might seem in the world’s eyes. This assumption is by no means inevitable. Most cultures have written about demigods and kings and heroes. Whatever the deeper reasons for the realist fascination with the ordinary, it is generous even when it is cruel, simply in the fact of looking as directly as it can at people as they are and insisting that insensitivity or banality matters. The Old Testament prophets did this, too.
