Famed biologist E.O. Wilson has recanted the evolutionary theory of kin selection:

apparent strategies in evolution that favor the reproductive success of an organism’s relatives, even at a cost to their own survival and/or reproduction.

Here is an explanation of Wilson’s change of mind:

I will concede a role for evolution in the development of human behavioral norms. But, as I say in “Evolution, Human Nature, and ‘Natural Rights’,”

The painful truth that vast numbers of human beings — past and present — have not acted and do not act as if there are “natural rights” suggests that the notion of “natural rights” is of little practical consequence….

Even if humans are wired to leave others alone as they are left alone, it is evident that they are not wired exclusively in that way.

Cooperative behavior is a loosely observed norm, at best. (For the benefit of “liberals,” I must point out that cooperation can only be voluntary; state-coerced “cooperation” is dictated by force.) Cooperation, such as it is, probably occurs for the reasons I give in “The Golden Rule and the State“:

I call the Golden Rule a natural law because it’s neither a logical construct … nor a state-imposed one. Its long history and widespread observance (if only vestigial) suggest that it embodies an understanding that arises from the similar experiences of human beings across time and place. The resulting behavioral convention, the ethic of reciprocity, arises from observations about the effects of one’s behavior on that of others and mutual agreement (tacit or otherwise) to reciprocate preferred behavior, in the service of self-interest and empathy. That is to say, the convention is a consequence of the observed and anticipated benefits of adhering to it.

I must qualify the term “convention,” to say that the Golden Rule will be widely observed within any group only if the members of that group are generally agreed about the definition of harm, value kindness and charity (in the main), and (perhaps most importantly) see that their acts have consequences. If those conditions are not met, the Golden Rule descends from convention to admonition.

Is the Golden Rule susceptible of varying interpretations across groups, and is it therefore a vehicle for moral relativism? I say “yes,” with qualifications. It’s true that groups vary in their conceptions of permissible behavior. For example, the idea of allowing, encouraging, or aiding the death of old persons is not everywhere condemned, and many recognize it as an inevitable consequence of a health-care “system” that is government-controlled (even indirectly) and treats the delivery of medical services as a matter of rationing…. Infanticide has a long history in many cultures; modern, “enlightened” cultures have simply replaced it with abortion. Slavery is still an acceptable practice in some places, though those enslaved (as in the past) usually are outsiders. Homosexuality has a long history of condemnation and occasional acceptance. To be pro-homosexual — and especially to favor homosexual “marriage” — has joined the litany of “causes” that signal leftist “enlightenment,” along with being for abortion and against the consumption of fossil fuels (except for one’s SUV, of course).

The foregoing recitation suggests a mixture of reasons for favoring or disfavoring certain behaviors. Those reasons range from purely utilitarian ones (agreeable or not) to status-signaling. In between, there are religious and consequentialist reasons, which are sometimes related. Consequentialist reasoning goes like this: Behavior X can be indulged responsibly and without harm to others, but there lurks the danger that it will not be, or that it will lead to behavior Y, which has repercussions for others. Therefore, it’s better to put X off-limits or to severely restrict and monitor it. Consequentialist reasoning applies to euthanasia (it’s easy to slide from voluntary to involuntary acts, especially when the state controls the delivery of medical care), infanticide and abortion (forms of involuntary euthanasia and signs of disdain for life), homosexuality (a depraved, risky practice that can ensnare impressionable young persons who see it as an “easy” way to satisfy sexual urges), alcohol and drugs (addiction carries a high cost, for the addict, the addict’s family, and sometimes for innocent bystanders). A taste or tolerance for destructive behavior identifies a person as an untrustworthy social partner.

It seems to me that the exceptions listed above are just that. There’s a mainstream interpretation of the Golden Rule — one that still holds in many places — which rules out certain kinds of behavior, except in extreme situations, and permits certain other kinds of behavior. There is, in other words, a “core” Golden Rule that comes down to this:

• Murder is wrong, except in self-defense. (Capital punishment is just that: punishment. It’s also a deterrent to murder. It isn’t “murder,” muddle-headed defenders of baby-murder to the contrary notwithstanding.)

• Various kinds of unauthorized “taking” are wrong, including theft (outright and through deception). (This explains popular resistance to government “taking,” especially when it’s done on behalf of private parties. The view that it’s all right to borrow money from a bank and not repay it arises from the mistaken beliefs that (a) it’s not tantamount to theft and (b) it harms no one because banks can “afford it.”)

• Libel and slander are wrong because they are “takings” by word instead of deed.

• It is wrong to turn spouse against spouse, child against parent, or friend against friend. (And yet, such things are commonly portrayed in books, films, and plays as if they are normal occurrences, often desirable ones. And it seems to me that reality increasingly mimics “art.”)

• It is right to be pleasant and kind to others, even under provocation, because “a mild answer breaks wrath: but a harsh word stirs up fury” (Proverbs 15:1).

• Charity is a virtue, but it should begin at home, where the need is most certain and the good deed is most likely to have its intended effect.

None of these observations would be surprising to a person raised in the Judeo-Christian tradition, or even in the less vengeful branches of Islam. The observations would be especially unsurprising to an American who was raised in a rural, small-town, or small-city setting, well removed from a major metropolis, or who was raised in an ethnic enclave in a major metropolis. For it is such persons and, to some extent, their offspring who are the principal heirs and keepers of the Golden Rule in America.

There is far more to human behavior than biological and evolutionary determinism. (Not that Wilson is guilty of that, but many others are.) It is especially simplistic to rely on biological and evolutionary explanations of the particular subset of behavioral rules known as “rights.” For the final word on that point, I return to “Evolution, Human Nature, and ‘Natural Rights'”:

[T]he Golden Rule represents a social compromise that reconciles the various natural imperatives of human behavior (envy, combativeness, meddlesomeness, etc.). Even though human beings have truly natural proclivities, those proclivities do not dictate the existence of “natural rights.” They certainly do not dictate “natural rights” that are solely the negative rights of libertarian doctrine. To the extent that negative rights prevail, it is as part and parcel of the “bargain” that is embedded in the Golden Rule; that is, they are honored not because of their innateness in humans but because of their beneficial consequences.
