[Y]our sheep that were wont to be so meek and tame, and so small eaters, now, as I hear say, be become so great devourers and so wild, that they eat up, and swallow down the very men themselves. They consume, destroy, and devour whole fields, houses, and cities. 9

Who were these sheep? Bizarre Dolly-like clones? Transgenic killer rams? No. More meant only that under the economic lure of the wool trade, the "noblemen and gentlemen" were attempting their own enclosure movement. 10

[They] leave no ground for tillage, they enclose all into pastures; they throw down houses; they pluck down towns, and leave nothing standing, but only the church to be made a sheep- house. . . . Therefore that one covetous and insatiable cormorant and very plague of his native country may compass about and enclose many thousand acres of ground together within one pale or hedge, the husbandmen be thrust out of their own.3 11

The sheep devour all. The dispossessed "husbandmen" now find themselves without land or money and turn instead to theft. In More's vision, it is all very simple. Greed leads to enclosure. Enclosure disrupts the life of the poor farmer. Disruption leads to crime and violence. 12

Writing 400 years later, Karl Polanyi echoes More precisely. He calls the enclosure movement "a revolution of the rich against the poor" and goes on to paint it in the most unflattering light. "The lords and nobles were upsetting the social order, breaking down ancient law and custom, sometimes by means of violence, often by pressure and intimidation. They were literally robbing the poor of their share in the common. . . ." 4 And turning them to "beggars and thieves." The critics of enclosure saw other harms too, though they are harder to classify. They bemoaned the relentless power of market logic to migrate to new areas, disrupting traditional social relationships and perhaps even views of the self, or the relationship of human beings to the environment. Fundamentally, they mourned the loss of a form of life. 13

So much for the bad side of the enclosure movement. For many economic historians, everything I have said up to now is the worst kind of sentimental bunk, romanticizing a form of life that was neither comfortable nor noble, and certainly not very egalitarian. The big point about the enclosure movement is that it worked; this innovation in property systems allowed an unparalleled expansion of productive possibilities. 5 By transferring inefficiently managed common land into the hands of a single owner, enclosure escaped the aptly named "tragedy of the commons." It gave incentives for large-scale investment, allowed control over exploitation, and in general ensured that resources could be put to their most efficient use. Before the enclosure movement, the feudal lord would not invest in drainage systems, sheep purchases, or crop rotation that might increase yields from the common—he knew all too well that the fruits of his labor could be appropriated by others. The strong private property rights and single-entity control that were introduced in the enclosure movement avoid the tragedies of overuse and underinvestment: more grain will be grown, more sheep raised, consumers will benefit, and fewer people will starve in the long run. 6 14

If the price of this social gain is a greater concentration of economic power, the introduction of market forces into areas where they previously had not been so obvious, or the disruption of a modus vivendi with the environment—then, enclosure's defenders say, so be it! In their view, the agricultural surplus produced by enclosure helped to save a society devastated by the mass deaths of the sixteenth century. Those who weep over the terrible effects of private property should realize that it literally saves lives. 15

Now it is worth noting that while this view was once unchallenged, 7 recent scholarship has thrown some doubts on the effects of enclosure on agricultural production. 8 Some scholars argue that the commons was actually better run than the defenders of enclosure admit. 9 Thus, while enclosure did produce the changes in the distribution of wealth that so incensed an earlier generation of critical historians, they argue that there are significant questions about whether it led to greater efficiency or innovation. The pie was carved up differently, but did it get bigger? The debate about these issues is little known, however, outside the world of economic historians. "Everyone" knows that a commons is by definition tragic and that the logic of enclosure is as true today as it was in the fifteenth century. I will not get involved in this debate. Assume for the sake of argument that enclosure did indeed produce a surge in agriculture. Assume, in other words, that converting the commons into private property saved lives. This is the logic of enclosure. It is a powerful argument, but it is not always right. 16

This is all very well, but what does it have to do with intellectual property? I hope the answer is obvious. The argument of this book is that we are in the middle of a second enclosure movement. While it sounds grandiloquent to call it "the enclosure of the intangible commons of the mind," in a very real sense that is just what it is. 10 True, the new state- created property rights may be "intellectual" rather than "real," but once again things that were formerly thought of as common property, or as "uncommodifiable," or outside the market altogether, are being covered with new, or newly extended, property rights. 17

Take the human genome as an example. Again, the supporters of enclosure have argued that the state was right to step in and extend the reach of property rights; that only thus could we guarantee the kind of investment of time, ingenuity, and capital necessary to produce new drugs and gene therapies. 11 To the question, "Should there be patents over human genes?" the supporters of enclosure would answer that private property saves lives. 12 The opponents of enclosure have claimed that the human genome belongs to everyone, that it is literally the common heritage of humankind, that it should not and perhaps in some sense cannot be owned, and that the consequences of turning over the human genome to private property rights will be dreadful, as market logic invades areas which should be the farthest from the market. In stories about stem cell and gene sequence patents, critics have mused darkly about the way in which the state is handing over monopoly power to a few individuals and corporations, potentially introducing bottlenecks and coordination costs that slow down innovation. 13 18
