Did Robert Nozick hold a view of the evolution of natural rights that is similar to that held by John Hasnas?

This question came to mind while I was reading Chapter 4 of John Hasnas’s recently published book, Common Law Liberalism: A New Theory of the Libertarian Society. Chapter 4 was originally published in 2005 in Social Philosophy and Policy (22, 111-147) but I hadn’t previously read it.

In this chapter, entitled ‘Empirical Natural Rights’, Hasnas suggests that neither John Locke nor Robert Nozick offered adequate arguments for the existence of natural rights. (His discussion of Nozick focuses on Anarchy, State, and Utopia.) He offers an alternative conception of natural rights – empirical natural rights (ENR) – that evolve in the state of nature. He then proceeds to argue that ENR form a good approximation to the negative rights to life, liberty and property on which Locke and Nozick rest their arguments, and that ENR have instrumental moral value.

In the first part of this essay, I outline Nozick’s evolutionary explanation for emergence of the ethics of respect. Following that, I compare the evolutionary accounts offered by Hasnas and Nozick, and finish the essay considering the normative status of ENRs.

Nozick’s evolutionary explanation for the ethics of respect

As far as I know, Nozick never claimed to have provided an account of the evolution of natural rights, but I believe that he did so in Chapter 5 of Invariances (published in 2001). Since I outlined Nozick’s speculations about evolution of the ethics of respect in Chapter 2 of Freedom, Progress, and Human Flourishing, I will reproduce some relevant paragraphs below:

“Nozick’s account of the evolution of the ethics of respect, draws upon biological evolution as well as cultural evolution. He suggests that the higher capacities of humans, including capacities for conscious thought, control of impulses and planning, have been selected for by evolution because of the benefits they bring, for example in enabling adherence to ethical norms.^[i] Evolution may have shaped humans to enjoy the benefits of cooperative activity. A reputation for adhering to norms of cooperative behavior brings rewards by attracting further cooperation, and may have conferred reproductive advantages.^[ii] A capacity for evaluating objects and desires might have been selected for, or exist as a beneficial side-effect of a combination of capacities.^[iii] Conscious self-awareness may have been selected for because it makes humans capable of norm-guided behavior to mutual benefit.^[iv]

Nozick suggests that internalization of norms brings ethics into play. Something other than (or in addition to) punishment by other people must support rules if they are to become ethical principles or values. The internalization of norms enables people to follow them when no-one is watching who can sanction deviations.^[v]

The norm of social coordination and cooperation proposed by Nozick has these characteristics:

“It makes mandatory the widest voluntary cooperation to mutual benefit; it makes only that mandatory; and it (in general) prohibits interactions that are not to mutual benefit, unless they are entered into voluntarily by all parties, or unless these interactions (such as the act of punishing another) are in response to previous violation of the principle or to preparations to violate it”.^[vi]

Moral progress, Nozick suggests, incorporates, among other things, shrinkage of the domain of mandatory morality to enable a domain of liberty and personal autonomy to be established, and for the ethics of respect to emerge.^[vii] 

Nozick acknowledges that someone could agree that ethics originates in mutually beneficial coordinating activity and yet claim that conscious self-awareness is valuable for reasons other than norm following. He sums up:

“Still, if conscious self-awareness was selected for because it makes us capable of ethical behavior, then ethics, even the very first layer of the ethics of respect, truly is what makes us human. A satisfying conclusion. And one with some normative force”.^[viii]

Since the ethics of respect entails recognition of Lockean rights, Nozick’s naturalistic explanation implicitly recognizes that such rights are natural.”

Comparison of Hasnas and Nozick

The differences between the evolutionary accounts offered by Hasnas and Nozick seem to me to amount to differences of emphasis. Nozick emphasized the link between conscious self-awareness and ethical behaviour, whereas Hasnas’s account seems to have a more Hayekian emphasis on evolution of rules that are not the result of deliberate human design. Hasnas emphasizes dispute settlement:

“Various methods for composing disputes are tried. Those that leave the parties unsatisfied and likely to again resort to violence are abandoned. Those that effectively resolve the disputes with the minimal disturbance to the peace of the community continue to be used and are accompanied by ever-increasing social pressure for disputants to employ them.

Over time, security arrangements and dispute settlement procedures that are well-enough adapted to social and material circumstances to reduce violence to generally acceptable levels become regularized.” (130)

 Hasnas acknowledges the normative significance of the rules that evolve:

“Over time, these rules become invested with normative significance and the members of the community come to regard the ways in which the rules permit them to act at their pleasure as their rights. Thus, in the state of nature, rights evolve out of human beings’ efforts to address the inconveniences of that state. In the state of nature, rights are solved problems.” (131)

The rules presumably came to have normative significance because people thought about them and recognized they had merit (aided by the persuasive efforts of Moses and other community leaders).

Hasnas does not claim that ENR fit the definition of natural rights as moral entitlements that humans possess simply by virtue of their humanity. He suggests that ENR are natural in the sense of having evolved in the state of nature and pre-date the formation of civil government.

I am not entirely persuaded that the distinction between ENR and natural rights is necessary. As far as I am aware, humanity didn’t exist prior to the biological and social evolution that resulted in the emergence of modern humans about 100,000 years ago.

Nevertheless, the question arises of whether it is possible to provide a normative justification for natural rights purely based on speculation about the evolutionary origins of ethical intuitions about rights to life, liberty and property.

The Normative Status of ENR

 Hasnas argues that ENR have instrumental moral value regardless of the moral theory and general approach to ethics one adopts:

“This is because empirical natural rights facilitate peaceful human interaction and peace is an important, if not pre-eminent moral value in virtually all moral theories.”

The author spends a few pages making this point. He has no difficulty persuading me of the importance of peace to the moral theory that I subscribe to. However, I see some groups of people in the world who claim to hold moral theories that support activities directed towards plundering, murdering, and enslaving others.

It seems to me that those of us who believe that peace is a pre-eminent moral value should be willing to provide explicit normative reasons why we consider peace to be so important.
