A Positive Account of Rights
During the time men live without a common power to keep them all
in awe, they are in that conditions called war; and such a war, as if of every
man, against every man.
Thomas Hobbes
In the previous chapter, I showed how it might be possible, in a toy society of two people, to bargain up out of a Hobbesian state of nature, a war of each against all, into an orderly and peaceful micro-society. In this chapter I apply the same approach to the world as it actually exists, a society in which large numbers of people interact, for the most part peacefully and cooperatively. In the process, I hope to provide answers to a number of different questions:
1. What are rights, considered not as a moral or legal category but as a positive category, a description of how people act.
2. How is it possible for civil order to exist—why are not all people, all of the time, in the Hobbesian state of nature, the war of each against all?
3. What is government—what distinguishes it from other human institutions?
And, as a free bonus,
4. Why did the U.K. send a fleet most of the way to Antarctica and risk its only aircraft carrier in order to defend a cluster of barren islands with a few hundred people on them.
Parts of the answers I will offer appear in Chapter 28, written more than forty years ago, but I believe that I understand them better now than I did then.
The Puzzle
Thomas Hobbes described the state of nature as a war of each
against all in which the life of man would be Òsolitary, poor, nasty, brutish, and short.Ó
That does not sound like the world we live in. His solution was to establish an
all powerful ruler. That comes a little closer to the real world, but not all
that close—and it is not clear how it could be done or why it would work.
In the state of nature, each individual acts in his
own interest. That sounds like a reasonably accurate description of our world. How
is his improved version, the world with a ruler, different? The ruler is not
superman; he too must sleep and can be killed while doing so. He may have a
police force and an army, but police forces and armies are made up of
men—what causes those men to act differently than anyone else? Where does
the structure of a real, orderly, peaceful society come from? What is the magic
ingredient that distinguishes civil order from the state of nature? It cannot
simply be laws—laws are words on paper that only take effect to the
extent that individuals act on them. Why should individuals act differently
after laws are passed than before? It cannot be police in uniforms and judges
in robes—in HobbesÕ day wigs as well. Uniforms, robes and wigs do not
confer magic power on their wearers or compel their wearers to act differently
than they would without them.
That is the central puzzle that this chapter
attempts to answer.
Neighborly
Extortion
Imagine that you live in a suburban neighborhood
with a not terribly efficient or well organized law enforcement system—as
many people do. One day your neighbor calls you over to the fence for
conversation. He explains that he finds taking his trash down to the town dump
every week to be a nuisance and has decided that it would be less trouble to
simply dump it over the fence onto your property.
When you recover your breath and start lecturing him
on property rights, he offers you a simple cost/benefit analysis of your
alternatives. Dealing with his trash will take about ten or twenty dollars
worth of your time and effort every week. Persuading the city authorities that
the trash is his and not yours, getting them do anything, appearing for
multiple court hearings, raising a general fuss, will cost you the equivalent
of considerably more than that.
But, he adds, he has an alternative proposal. For
him to dump the trash and someone else to collect it is clearly inefficient. A
better solution is for him to deal with his trash and you to pay for it. For a
mere five dollars a week, half or less what your lowest cost solution to the
problem would cost you, he will agree to refrain from dumping the trash over
the fence.
I predict that you will turn down his generous
offer, tell him to go to hell and, if he persists in dumping his trash on your
property, spend the equivalent of considerably more than five dollars a week,
or even ten or twenty, prodding the relevant authorities into doing something
about the problem. Why?
The answer is a fancier version of the territorial
behavior discussed in the previous chapter. You, like a territorial bird or
fish, have adopted a commitment strategy; the only difference is that yours is
more complicated because your territory is not defined not as a territory but
as a set of rights. There are certain things you consider yourself entitled to
in your interaction with other people, and one of them is not having trash
dumped on your property. In defense of those rights you, like the territorial
animal, are willing to bear costs out of proportion to what is immediately at
stake.
A different way of putting the point is that, if you
give in to your neighborÕs attempt at small scale extortion, there is no
obvious limit to how far it will go. There are, after all, quite a lot of other
ways in which he, or other people, could impose costs on you or demand payment
not to. By adopting a policy of resisting such demands even at considerable
cost, you give other people an incentive not to make them—and if they do
not make them, you do not need to bear the cost of resisting them.
What prevents your neighbor, following the same
logic, from commiting himself to bear large costs if you donÕt give in to his
extortion? The short answer is that you will not believe him. The long one is
that you are defending a Schelling point, defined by your (and his!) perception
of individual rights. Given the existence of only one such Schelling point, one
settlement of your potential conflicts that appears unique to both of you, it
makes sense for you to defend it, just as it makes sense for the bank robber in
our earlier story not accept any offer below half the loot.
The logic of the situation does not depend on the
existence of law, nor on any shared morality to support the rights you claim.
All that it requires is that both of you know what rights you claim and both of
you know that the claim is unique—you cannot believably insist that your
rights consist of no trash plus his paying you a modest tribute, any more than
he can insist on the same terms the other way around.
A
Little More on Schelling Points
A crucial point here is a feature of a Schelling
point that I did not make explicit in my previous discussion—the fact
that its existence is a subjective, not objective, feature of reality. It is a feature
of how the interacting parties view the world. Consider the following simple
example:
Two people are presented with the following list of
numbers and offered a prize if they succeed, without communication, in both
selecting the same one:
2,
5, 9, 25, 69, 73, 82, 100, 126, 150
Each of them, as per the previous discussion, is looking for
a number that is somehow unique—but which numbers are unique depends on
how each of them thinks about numbers. To many ordinary people, 100 seems to be
a round number in a sense in which the others are not. To a mathematician, all
that is special about it is that it is an exact square—and the list
contains two others. It may, however, occur to the mathematician—assuming
he is coordinating with another mathematician—that in the entire set of
positive integers there exists only one even prime, making it the obvious
choice. To someone who is illiterate and sees the numbers only as
patterns, 69 will seem unique for
its symmetry—conveniently letting him coordinate with someone whose
interest is more prurient than mathematical. There is no objectively right
answer to what is the right number. It depends on how the person you are
coordinating with sees the world.
For a somewhat more strained example of the same point, go
back to our bank robbers, with one difference. They happen to come from a society
dominated by utilitarians and have been taught to measure money—and
everything else of value—not in dollars but in utiles, units of
happiness. Furthermore, everyone in their society believes that the marginal
utility of income is inverse to wealth—if you have twice as many dollars
as I do, you value each additional dollar at exactly half as much as I do.
To these philosophical robbers, the obvious division is
still fifty-fifty, an even split, but it is an even split of utility, not
money. One of them happens to be twice as wealthy as the other, so an even
split, one that gives him half thef utility, must give him two thirds of the
dollars.
What the two robbers agree on is not how much each one is
morally entitled to—we can assume, as before, that each believes he did
more than half the work and so deserves more than an even share. We could even
assume that both agree which did more than half the work. Provided that they do
not agree about how much, that agreement does not generate a Schelling point to
coordinate on. Their agreement about what defines a fifty-fifty split does.
I emphasize this point because one possible
explanation of social order is morality—individuals refraining from
murder, rape, and robbery because they believe such actions are wrong. That is a
possible explanation, but not the one I am offering here. My claim is that even
without moral agreement, even without any moral belief at all, a pattern of
consistent commitment strategies makes coordination possible.
Escaping the State of Nature
I have now offered a solution to the puzzle I started with. What is added to a state of nature in order to turn it into civil order, to convert the war of each against all into peace, is a network of commitment strategies based on an elaborate set of mutual perceived Schelling points. It could be based on shared religious or ideological beliefs, but need not be. What matters is that each person is committed to bearing substantial costs to maintain his commitment strategy, that people for the most part correctly perceive each othersÕ commitment strategies, and that those strategies are for the most part consistent—I am not committed to getting from you something you are comitted to not giving me.
The form in which individuals bear costs to enforce their commitments will vary with context. In the previous chapter it involved the actual use of force, whether against people or trees. In my tale of suburban extortion, the weapons are more likely to be lawyers than axes. But in both versions and many others, it is the pattern of commitment that gives order to the society and the existence of a commonly perceived network of Schelling points that makes possible that pattern of commitment.
Why Hobbes was wrong
One implication of this way of viewing an orderly society is that Hobbes was wrong. A society may be in a state of nature in the sense of not having an all powerful sovereign, even of not having a sovereign at all, and still be a great deal more orderly than he imagined. The clearest real world examples would be primitive stateless societies such as the Commanche. They had nothing we would recognize as a government, but killing a man or seducing his wife had consequences, consequences due to the commitment strategies of other members of the society, consequences that made such actions much less common than they would be in HobbesÕ version of the state of nature.
And why Hobbes was right
The same view of human behavior shows why HobbesÕ solution, if not necessary, was at least possible. His version of an orderly society, rule by an all powerful sovereign, is simply supported by a different pattern of commitment strategies and Schelling points, one in which ordinary individuals are committed to resist what they see as rights violations by other individuals but not similar actions by the sovereign or his agents and in which the relations of the sovereign and his agents are structured into a hierarchy of authority by their own self-consistent network of commitment strategies.
For a simplified version, suggested to me long ago by the late Earl Thompson, imagine that the ruler can successfully commit himself to kill any of three subordinates if they defy his orders—and has ordered each of them to make a similar commitment to control three of their subordinates. Continue the cascade until there are enough people in it to believably threaten any of those outside the ruling clique—who, since they are not committed to defy such threats, will yield whenever yielding is less costly than resisting. Each individual, inside and outside government, is acting in his own rational self interest, given what everyone else is doing—what game theorists describe as a Nash Equilibrium.
A Positive Account of Rights
This way of looking at behavior provides a way of understanding rights that depends on neither law nor morality, although it might be reinforced by either. From this perspective, the fact that I have a right not to be killed means neither that killing me is wicked nor that it is illegal, only that it will usually not be in other peopleÕs interest to do it. That particular right is enforced by the commitment strategies of other people—in the Icelandic society described in Chapter 44, the commitment of my kin to use violent force against anyone who kills me and refuses to pay the wergeld that the court awards me. More generally, my rights are whatever I am successfully committed to defend, where success depends in part on other people recognizing my commitment and having no commitment of their own that directly clashes with it.
What is Government, What is Anarchy
This approach provides a clearer answer to that question than I was able to give in the first edition of this book. A government is an institution against which people have dropped the commitment strategies that defend what they view as their rights against other people. An anarchy is a society in which there is no such institution. An anarchist is someone who sees such a society as desirable. All of that was, I think, implicit in Chapter 28, where I defined a government as an agency of legitimized coercion. But I understand it more clearly now.
And What the British Navy Was Doing in the Falklands
This way of looking at individual behavior also explains some of the behavior of governments. ArgentinaÕs invasion of the Falkland islands triggered a British commitment strategy: Respond with force to anyone seizing British territory. Britain responded by sending a fleet most of the way to the South Pole to get the islands back. It made very little sense viewed in immediate cost/benefit terms—it would have been a great deal cheaper to transport all of the inhabitants to England and give each of them enough money to support him for the rest of his life. But it made a great deal of sense given that Òdefend our boundariesÓ was a Schelling point and Òdefend our boundaries except when Argentina invades the FalklandsÓ was not.
Credits
In addition to Thomas Schelling, the ideas of this chapter owe most to the late Earl Thompson, possibly the most brilliant not-very-famous economist I have known; an economics Nobel of my acquaintance, not related to me, once described him as having the highest IQ of anyone he knew. It was Earl who first convinced me of the importance of commitment strategies in understanding human behavior and the structure of human societies. Credit also goes to Gordon Tullock for provoking me into thinking through the ideas, as described in the previous chapter.
