Looking Back on Tomorrow

If the century ahead turns out to have a theme, what will it be?

What are we going to do with our lives? I don't mean that question in any small, personal sense; whether or not you decide to retire early to open a bed-and-breakfast is of no interest to me. I mean it in the biggest sense. Which issues will dominate the twenty-first century? What debates and controversies will roil our children's lives? In other words, what will the twenty-first century be about?

If forced to sum up nineteenth-century America in one sentence, I'd say that it was about national union. The century opened with the Louisiana Purchase and continued with the acquisition and settling of the West. Then came efforts to link our vast space with networks of canals, railroads, towns, and telegraph wires. The Civil War was, of course, an all-out fight for political and cultural union. And the century ended with the consolidation of the national economy.

The twentieth century, in America and elsewhere, was about the size of government. The main debate was between those who wanted to preserve limited government and those who wanted a bigger and more active government, whether the latter were Progressives, New Deal liberals, democratic socialists, or totalitarians. Two of the great conflicts of the century, World War II and the Cold War, were fought against ideologies—fascism and communism, respectively—that held that the state should control economic and social life. In the United States election after election revolved around the question of small versus big government.

From the archives:

"A Triumph of Misinformation" (January 1995)
Most of what everyone "knows" about the demise of health-care reform is probably wrong—and, more important, so are the vague impressions people have of what was really in the Clinton plan. By James Fallows

It is hard to believe that the debate about the right size of government will dominate the coming century. Most nations have reached a rough consensus on the matter. In the United States federal expenditures now equal about one fifth of GDP, as they have for many years; there is no sign that that figure will change much anytime soon. In 1993 Hillary Clinton tried to expand the scope of government by offering an enormous proposal to reform health care, and in 1995 the speaker of the House, Newt Gingrich, tried to shrink it. Both failed. Democrats and Republicans still attack each other on the issue, but their fight has become a sort of petty trench warfare on familiar terrain, marked by tired arguments and no significant movement one way or the other.

Which project or controversy, then, will define the coming century? Here are a few nominees:

Remaking human nature. We are experiencing a biotechnological revolution. In his book Life Script (2001), Nicholas Wade, a science reporter for The New York Times, predicts that the revolution will wash over us in three overlapping waves. First will come what has been called individualized medicine. Doctors will match drugs to our specific genotypes and will even introduce "regenerative medicine": instead of fixing diseased organs, they will grow and implant new ones. The second wave will bring breakthroughs in gene therapy as it applies to reproduction. Fertilized eggs will be treated in vitro with selected genes to increase the future person's height or intelligence, for example, or to prevent depression or other illnesses. The result of these advances will be a third wave: a radical increase in how long people live. Wade suggests that we may eventually regard 320 years as a normal life-span.

Breakthroughs of this sort would certainly reduce disease and suffering. But they would also raise many doubts, which can be boiled down to two questions: Is there more to life than maximizing pleasure and minimizing pain? Do we improve our bodies at the cost of our souls?

Critics of the drive toward such technologies argue that we take on a terrible burden when we try to redesign human nature and human beings. Parents who try to implant "improvements" in their prospective children, they contend, will be perverting parenthood. They will be assessing their children in consumerist terms, not regarding them as intrinsically holy creations (see "Jack or Jill?," by Margaret Talbot, March Atlantic). And parenthood will become despotism as parents refuse to accept limits on their control over another human life.

Regarding the third wave of Wade's revolution, would a radically longer life necessarily be a better life? "Teach us to number our days," the Psalmist says, "that we may apply our hearts unto wisdom." We seek to live according to God's word, the critics argue, precisely because we are aware that our time on earth is short.

The forces of science say that they are attempting to master nature in order to improve man's estate, in the spirit of the Baconian tradition. The forces of religion say that at some point the domination of the flesh becomes the death of the spirit.

Globalization. Before the terrorist attacks in New York and Washington, most social scientists would have predicted that the economics and politics of globalization would dominate the twenty-first century. One of the classic texts in this debate is The End of the Nation-State (1995), by the French intellectual Jean-Marie Guéhenno. Guéhenno begins with the familiar argument that nations are too big to solve some problems and too small to solve others. However, he deepens the discussion when he writes that certain concepts associated with the nation-state, such as democracy, politics, and liberty, continue to define our horizons but no longer mean what they once did.
