In 1958, Leonard Read wrote one of the most famous essays in the history of libertarianism, “I, Pencil.” It begins, “I am a lead pencil — the ordinary wooden pencil familiar to all boys and girls and adults who can read and write.” It is one of the most simple objects in human civilization. And yet, “not a single person on the face of this earth knows how to make me.”

The pencil tells the story of its own creation. The wood comes from Oregon, or perhaps California. The lead, which is really graphite, is mined in Ceylon (now Sri Lanka). The eraser, which is not rubber but something called “factice,” is “made by reacting rape-seed oil from the Dutch East Indies with sulfur chloride.”

To make a long story short, the simple act of collecting and combining the ingredients of a pencil involves the cooperation of thousands of experts in dozens of fields, from engineering and mining to chemistry and commodity trading. I suppose it’s possible for someone to master all of the knowledge and expertise to make a pencil all by himself, but why would he?

The lessons one can draw from this fact are humbling. For starters, any healthy civilization, never mind any healthy economy, involves unfathomably vast amounts of harmonious cooperation.

The modern market economy is the greatest communal enterprise ever undertaken in the history of humanity. Friedrich Hayek did the heavy lifting on this point over half a century ago in his essay “The Use of Knowledge in Society.” The efficient pricing of markets allows millions of independent actors to decide for themselves how to allocate resources. According to Hayek, no central planner or bureaucrat could ever have enough knowledge to consistently and successfully guide all of those economic actions in a more efficient manner.

The latest proof of Hayek’s insight can be found not only in the economic winter that goes by the label “recovery summer,” but in the crown jewel of the stimulus known as “cash for clunkers,” which subsidized car purchases that would have happened anyway. That’s a major reason the auto industry just had its worst August in 27 years. Meanwhile, lower-income buyers are seeing used-car prices soar thanks to the artificial scarcity created by destroying perfectly good “clunkers.”

But that’s a small point in the grand scheme of things. According to progressives, the financial crisis discredited “market fundamentalism” and created a burning need for a more cooperative society where “we’re all in it together.” It’s an ancient argument, with many noble intentions behind it. But it rests on a misunderstanding of one simple, astounding, irrefutable fact. The market economy is cooperative, and more successfully so than any alternative system ever conceived of, never mind put into practice. Admittedly it doesn’t feel that way, which is why everyone wants to find a better replacement for it. But they never will, for the same reason no one can make a pencil.
