Nozick on Rights

Overview

We discussed Nozick’s claim that rights are what he calls “side-constraints,” meaning that they constrain actions: no one can do anything that would violate another person’s rights.

Nozick vs. Utilitarianism

I characterized utilitarianism as having two parts:

  1. A hedonistic account of good and bad, according to which things are good (or bad) only because they produce pleasure (or pain).

  2. A consequentialist or maximizing account of right and wrong, according to which the right action is the one that produces more good than the available alternatives (after their bad effects are subtracted, of course).

In the chapter we read today, Nozick takes on both parts.

His example of the experience machine is meant to challenge the hedonistic account of good and bad. Roughly, if you think it matters whether you are really doing things in the world, then you think there is something good (or bad) other than pleasure (or pain): really doing things or interacting with others (rather than merely thinking you are doing so). Jordan and others were pretty clear that this is how they felt.

But most of his fire is aimed at the consequentialist account of right and wrong. Nozick thinks it cannot accommodate individual rights.

Hedonism

We spent a lot of time talking about the utilitarian’s hedonistic account of good and bad.

Stevie got the conceptual ball rolling by pointing out that questions about good (and bad) are normally different from questions about right (and wrong). So you could have an action that is wrong but good: stealing from the rich to give to the poor, for instance. One interesting thing about utilitarianism is that it doesn’t have this kind of split. The right action is always the one that produces the most good and the wrong action is the one that doesn’t. So if stealing from the rich to give to the poor really does produce the most good, that’s the right thing to do for a utilitarian.

Ruben said he didn’t want to get in the experience machine because he wants to learn. We learn things from unpleasant experiences and so a life spent in a machine that produces only pleasant experiences would be one with less learning than a life spent outside of such a machine.

Liam said that Ruben had not gotten to the fundamental issue. He said that there could be a machine that doesn’t give you the most pleasant life but rather one that gives you the most learning.

I see what Liam was getting at, but for the question at hand, I think Ruben’s point was still a good one. The question is whether pleasure is the only thing that is good. Nozick’s machine was meant to convince us that there is at least one thing better than pleasant experiences: real life. But Ruben was saying that there is another thing that is better than pleasant experiences: learning. Nozick wanted to focus on the difference between an artificial life filled with whatever kinds of experiences you want and a real life. That’s what Liam was talking about. Ruben’s point wasn’t about the difference between real and artificial experiences but it was still relevant to the question of whether pleasure is the only good thing in life.

In a similar vein, Amadi noted that education can cause you to lose comfortable beliefs. But we still think it’s better to be educated than ignorant even if that makes you unhappy.

Katya said that she thinks a meaningful life is one that attempts to make sense of reality, no matter how disordered, random, or unpleasant it is.

Rights and Goals

As I said, Nozick is mostly interested in the consequentialist theories of right and wrong. He thinks that the problem with this is that it treats right and wrong as goals: an action is right if it fits the goal of promoting utility and wrong if it does not.

But, according to Nozick, this is not so. He assumes that an action is wrong if it violates an individual’s rights. And he argued that we do not treat rights as goals. He illustrates this with one of the stylized examples that are used to raise objections to utilitarianism: suppose the town sheriff can execute one innocent person to save ten innocents from dying in a riot that will happen if the innocent person is not executed.

Obviously, if we are working only within a system of goals, and one of those goals is to save innocent life, then we should kill the one to save the ten. But Nozick says that this ignores the rights of the one not to be killed. The sheriff should respect rights first and doing so rules out killing the one innocent person.

How would you respond if you were a utilitarian? The first thing you should do is deny that violating individual rights really would maximize utility. When you start asking questions about how this is supposed to work, it’s hard to see that violating the individual’s rights really does maximize utility. The example as given ignores all the bad consequences of executing an innocent person and it makes a highly artificial assumption that killing the one innocent person is the only thing that can be done to save the ten. In a more realistic example, utilitarianism would not recommend violating individual rights, a utilitarian will say.

But suppose we insist on the facts as stipulated in the example: it really is true that there is nothing else to do to save the ten innocent people. The ten orphans are innocent too and, if utilitarians are really genuinely honestly cornered into making a choice between one innocent life and ten innocent lives, they are comfortable with using an old standby: arithmetic. The choice is terrible, but if it’s forced on you, it’s better to lose one life than it is to lose ten.

If individual rights are absolute, such that you can’t kill one in order to save ten, then they are hopelessly paradoxical, according to the utilitarian. After all, the orphans have rights to life too. Why is the violation of ten people’s rights preferable to the violation of one person’s rights?

This is a powerful one-two punch for the utilitarians. Still, Nozick points out that this is not the way we think about rights. We do not think that whether someone’s rights are to be respected or not depends on calculating the effects of doing so. And we are not willing to engage in the kinds of trade-offs that the utilitarians claim are sensible.

Nozick thinks this shows that we do not treat rights as goals, where we would try to maximize achievement of the goal. Instead, we treat rights as what he called side-constraints. In this case, the innocent person’s rights act as a constraint on what the sheriff may do: the sheriff may not do anything that would violate the innocent person’s rights. If that is incompatible with reaching the goal of saving as many innocent lives as possible, that’s the way it goes. Individual rights take priority over the achievement of even worthy social goals.

Digression: Why Isn’t This a Dilemma?

Why doesn’t our poor sheriff face a dilemma? The side constraint “never kill the innocent” tells him not to kill the innocent guy and the side constraint “protect the innocent from being killed” tells him that he must kill the innocent guy (in these admittedly weird circumstances).

The answer is that Nozick only believes there is one side constraint at play in this case. We are forbidden from killing, but we are not required to prevent others from killing. Thus there is no dilemma here. The sheriff may not kill the innocent person. If he can save the innocents without violating a side constraint he may do so. But he is not required to do that and so there is no conflict of requirements here.

This would be irrational if rights were based on goals, such as the goal of minimizing the number of innocent deaths. But, again, Nozick does not think rights are based on goals. His case against utilitarianism is that the utilitarians improperly treat rights as if they were derived from goals.

Why Do We Have Rights?

Suppose Nozick is correct and that rights are not derived from goals. What are they based on?

Nozick’s attempts to explain why we have rights that are side constraints take him through several long and interesting digressions. He takes it for granted that our rights must be based on some natural features that we all share and he went on a search for those features.

He concluded that the natural features in question are ones that enable us to guide our lives by plans. That, in turn, is said to be important because it is how we give meaning to our lives (Nozick 1974, 48–50).

While suggestive, Nozick’s arguments are thin. He sometimes tries to get by with a quick reference to a phrase from Immanuel Kant about treating people as ends and not means. We will have to pay attention to this later. Nozick’s version of libertarianism rests heavily on his conception of rights. We will need to see whether it is enough for him to show that rights take the form of non-utilitarian side constraints or if he needs a deeper explanation of what rights we really have.

Nozick’s libertarianism vs. Mill’s libertarianism

Nozick and Mill endorse quite similar principles. Mill’s harm principle holds that individuals should be left free to do anything that does not harm others: “the sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self-protection” (Mill [1859] 2000, ch. 1, par. 9).

Similarly, Nozick holds that “there is no justified sacrifice of some of us for others” and that there is “a libertarian side constraint that prohibits aggression against another” (Nozick 1974, 33).

However the philosophical bases of their respective versions of libertarianism are quite different. Nozick thinks the state is limited to protecting rights. Mill has to think it is committed to maximizing overall utility, even if this comes at the cost of rights. Furthermore, Nozick maintains that individual rights are derived from features of the individuals themselves and that one person’s rights cannot be balanced against another’s. Mill, on the other hand, derives individual rights from overall utility. If protecting individual liberty were not the best way of promoting the social good, Mill would have to reject it.

Furthermore, they have different opinions about what kinds of liberty are most important. Nozick emphasizes economic liberty. He thinks that “the state may not use its coercive apparatus for the purpose of getting some citizens to aid others.” Its sole function is to protect people “against force, theft, fraud,” and violations of contractual agreements. Anything more is “redistributive,” limiting one person’s liberty for another person’s sake (Nozick 1974, ix). Mill believes that there is a utilitarian case for economic liberty. But he also believes that it is separate from the one he made in On Liberty (Mill [1859] 2000, ch. 5, par. 4). On Liberty defends individual liberty of thought, expression, association, and determining how to live. Mill regards commercial activity as something different.
