On Steven Pinker’s “Rational” Morality

According to the Amazon blurb on “Rationality,” Steven Pinker’s latest book, “Rationality matters. It leads to better choices in our lives and in the public sphere, and is the ultimate driver of social justice and moral progress.” In fact, Pinker addresses the issue of morality in the book. However, the degree to which he’s rational about it is open to question. According to Pinker,

One realm that is sometimes excluded from the rational is the moral. Can we ever deduce what’s right or wrong? Can we confirm it with data? It’s not obvious how you could. Many people believe that “you can’t get an ought from an is.” The conclusion is sometimes attributed to the philosopher David Hume. “Tis not contrary to reason.” He famously wrote, “to prefer the destruction of the whole world to the scratching of my finger.”

Pinker then goes on to tell us that, “Philosophers in the first half of the twentieth century took Hume’s argument seriously and struggled with what moral statements could possibly mean if they are not about logic or empirical fact,” and “Hume may have been technically correct when he wrote that it’s not contrary to reason to prefer global genocide to a scratch on one’s pinkie. But his grounds were very, very narrow.” Pinker doesn’t elaborate on the latter statement, probably for the very good reason that it’s nonsense. Hume’s grounds weren’t “narrow” at all. They were a straightforward elaboration of what had already been written on the subject by, among others, the Earl of Shaftesbury, and, more importantly, Francis Hutcheson.

Using Pinker’s prized “rationality,” Hutcheson demonstrated beyond any “rational” doubt that morality can’t be derived from reason, either narrowly or broadly, but must originate from what he referred to as a “moral sense.” His brilliant, “An Essay on the Nature and Conduct of the Passions and Affections, with Illustrations on the Moral Sense,” includes such amazingly “modern” passages as,

These Moral Perceptions arise in us as necessarily as any other Sensations, nor can we alter, or stop them.

Let us once suppose Affections, Instincts or Desires previously implanted in our Nature: and we shall easily understand the exciting Reasons for Actions.

The Question then is, “Does a Conformity to any Truth make us approve an ultimate End, previously to any moral Sense?” For example, we approve pursuing the publick Good. For what Reason? Or what is the Truth for Conformity to which we call it a reasonable End? I fancy we can find none in these Cases, more than we could give for our liking any pleasant Fruit.

These passages were published in 1728, more than a century before Darwin, so it is not surprising that Hutcheson imagined that God was the source of our moral sense. We now know that it exists as a result of natural selection, because the innate predispositions that give rise to it happened to increase the odds that our ancestors would survive and reproduce.

Hume presented similar arguments, but with a more secular foundation. Pinker’s attempt to relegate him to the “first half of the twentieth century” is absurd. I can only suggest that he consult “The Righteous Mind,” by his fellow public intellectual, Jonathan Haidt, published as recently as 2012. Therein he will find a significantly more “rational” discussion of Hume. Speaking of individuals in a study who were “morally dumbfounded – rendered speechless by their inability to explain verbally what they knew intuitively,” Haidt wrote,

These subjects were reasoning. They were working quite hard at reasoning. But it was not reasoning in search of truth; it was reasoning in support of the emotional reactions. It was reasoning as described by the philosopher David Hume, who wrote in 1739 that “reason is, and ought only to be the slave of the passions, and can never pretend to any other office than to serve and obey them.

A bit later in the book Haidt writes,

Given Hume’s concerns about the limits of reasoning, he believed that philosophers who tried to reason their way to moral truth without looking at human nature were no better than theologians who thought they could find moral truth revealed in sacred texts. Both were transcendentalists.

Recall, now, that Pinker imagines himself a great fan of the Enlightenment, and even published a book with that title. Haidt continues,

Hume’s work on morality was the quintessential Enlightenment project; an exploration of an area previously owned by religion, using the methods and attitudes of the new natural sciences… Hume got it right. When he died in 1776, he and other sentimentalists had laid a superb foundation for “moral science,” one that has, in my view, been largely vindicated by modern research. You would think, then, that in the decades after his death, the moral sciences progressed rapidly. But you would be wrong. In the decades after Hume’s death the rationalists claimed victory over religion and took the moral sciences off on a two-hundred-year tangent.

Now we find Pinker off on this same tangent, a self-described “rationalist,” rejecting one of the quintessential works of the Enlightenment he claims to champion. In fact, Hume’s relevance to the question of morality is at least as great today as it was a decade ago. Apparently Pinker never actually read Hume, or, if he did, didn’t comprehend what he was reading. Hume, and Hutcheson before him argued very convincingly that you could follow a chain of reasons back as far as you pleased, but you would never find some ultimate reason as the source of human morality, for the very good reason that the foundation of morality lies in human emotions and human nature. Pinker never attempts to challenge these arguments. Instead, he imagines he can hand-wave them out of existence by claiming they’re too “narrow.” The same goes for his fantasy that Hume is no longer relevant “since the first half of the 20th century.”

After his breezy dismissal of Hume, Pinker writes, “In fact, it is not hard to ground morality in reason.” Let’s consider the “rationality” of his arguments in favor of that statement. According to Pinker,

But now let’s just say that we prefer good things to happen to ourselves over bad things. Let’s make a second wild and crazy assumption: that we are social animals who live with other people, rather than Robinson Crusoe on a desert island, so our well-being depends on what others do, like helping us when we are in need and not harming for no good reason.

This changes everything. As soon as we start insisting to others, “Your must not hurt me, or let me starve, or let my children drown,” we cannot also maintain, “But I can hurt you, and let you starve, and let your children drown,” and hope they will take us seriously.

Well, no, they won’t take us seriously, but how does that “change everything?” Why does Pinker imagine there’s any connection between being taken seriously and morality to begin with? He continues,

That is because as soon as I engage you in a rational discussion, I cannot insist that only my interests count just because I’m me and you’re not, any more than I can insist that the spot I am standing on is a special place in the universe because I happen to be standing on it. The pronouns I, me, and mine have no logical heft – they flip with each turn in a conversation. And so any argument that privileges my well-being over yours or his or hers, all else being equal, is irrational.

It’s hard to imagine anything more irrational than this. Does Pinker imagine that human beings are no different than the indistinguishable particles of physics? If what Pinker writes is true, then the genes that are responsible for the existence of morality must be completely irrational, because, to the extent that they fail to “insist that only their interests count,” they quickly go extinct. Apparently, we are to forget about the reasons morality exists, and simply agree with Pinker that whatever he personally feels is “fair,” must therefore be moral. QED. Lions must be both irrational and immoral because they kill the cubs sired by others so they can substitute their own. Male gorillas must be irrational and immoral because they kill unprotected infants, a behavior which promotes their own genetic interests, but which Prof. Pinker would doubtless consider manifestly unfair.

Pinker doesn’t entirely ignore the evolutionary origins of morality, writing, for example,

How do rational agents come into existence in the first place? Unless you are talking about disembodied rational angels, they are products of evolution, with fragile, energy-hungry bodies and brains. To have remained alive long enough to enter into a rational discussion, they must have staved off injuries and starvation, goaded by pleasure and pain. Evolution, moreover, works on populations, not individuals, so a rational animal must be part of a community, with all the social ties that impel it to cooperate, protect itself, and mate.

This passage is truly ironic. Some time ago in his bowdlerized history of the Blank Slate, Pinker air brushed out of existence the two men most responsible for the demise of the Blank Slate orthodoxy in the behavioral sciences, Robert Ardrey and Konrad Lorenz, because they claimed that “evolution acted for the good of the species.” Now we find him making exactly the same claim. Elsewhere he makes it clear that he does not believe that natural selection acts at the level of populations, but so did Ardrey and Lorenz. Is it not, then, “rational” to dismiss Pinker as well, based on his own arguments? Reading on, we find,

When you combine self-interest and sociality with impartiality – the interchangeability of perspectives – you get the core of morality. You get the Golden Rule… Versions of these rules have been independently discovered in Judaism, Christianity, Hinduism, Zoroastrianism, Islam, and other religions and moral codes.

That’s certainly good evidence that human moral emotions tend to be similar across populations, just as one would expect if those emotions exist because they evolved. However, it is hardly rational to conclude that the similarity of these rules somehow means they are objectively true, independently of the emotions responsible for their existence in the first place. Pinker continues,

Impartiality, the main ingredient of morality, is not just a logical nicety. Practically speaking, it also makes everyone, on average, better off. Life presents many opportunities to help someone, or to refrain from hurting them, at a small cost to oneself. So if everyone signs on to helping and not hurting, everyone wins. This does not, of course, mean that people are in fact perfectly moral, just that there’s a rational argument as to why they should be.

Really? Help them do what? Isn’t it wise to consider what their goals happen to be, and whether they either support or diametrically oppose our own before we “help” them accomplish those goals? Does Prof. Pinker seriously believe that everyone on the planet must have the same goals, and they must be identical to his own? Apparently, we are to dismiss anyone who doesn’t agree with Prof. Pinker on what our goals ought to be as “irrational.”

Indeed, one is at a loss to imagine what species Pinker is thinking about. It can’t be human beings. Regardless of what culture or ethnic group we belong to, we perceive others in turns of ingroups and outgroups. Our species is never “impartial” when it comes to treatment of the “other,” the denizen of the outgroup. That is simply a fact, and to deny it would be the very opposite of rationality. All Pinker is really doing is insisting that the types of behavior he and his academic tribe consider “nice” must therefore magically be “moral,” and to disagree is to be, by definition, “irrational.”

To be “rational,” we must ignore the reasons morality exists to begin with. To be “rational,” we must abandon the goals we have set for ourselves in life if Prof. Pinker and his tribe don’t deem them “nice,” regardless of whether those goals are in harmony with the genetic origins of morality or not. To be “rational,” we must forget about the relevance of our behavior to either our own genetic survival or the long-term survival and continued evolution of our species. To be “rational,” we must assume that behavioral traits that evolved eons ago, because they happened to promote the survival of individuals living in small groups of hunter gatherers, will automatically be just as “useful” to us today. In the process, we must ignore the fact that, while such individuals may have helped members of their own group, they were generally hostile to individuals in the next group over. It never occurred to them to help these “others.” No, we must limit ourselves to behaviors that Prof. Pinker deems “fair,” on pain of being anathematized as “irrational.”

No thanks, Prof. Pinker. Your version of morality is the very essence of irrationality.

Academic Follies: Chasing the Mirage of Objective Morality

The human mind is beset by no more powerful illusion than the belief in objective morality; that good and evil exist as things, independent of how or what we imagine them to be. One of the more whimsical proofs of this is the obvious survival of the illusion in the minds of those who, to all appearances, realize that morality exists because it evolved, and even claim to believe that it is subjective. For example, our purported experts in the behavioral sciences are all afflicted by the mirage, as far as I know without exception, and regardless of what they happen to say about it.

Examples of the above anomaly are particularly easy to find in the case of the denizens of academia. They may pledge their allegiance to Darwin, but they belong to an ingroup that requires their actual allegiance to a moral code that is subject to change from day to day, but is de rigueur regardless. The synthesis of this clash of thesis and antitheses is what George Orwell referred to as “doublethink.” These worthies may claim that morality is subjective, but accept the “objective” moral law of their ingroup without question. We find them declaring that one type of behavior is morally abhorrent, and another kind is “good,” to all appearances blithely unaware that there is anything even remotely contradictory in their behavior.

If Darwin was right, and morality is subjective, then there can be no truly evil or truly good individuals, because no such categories exist. Just as there are no preferred inertial reference frames in an Einsteinian universe, there are no preferred moral reference frames in the moral universe. An individual can certainly say that one thing is good and another evil according to his personal moral reference frame, but he can never claim that one thing is absolutely good and another absolutely evil. In spite of that, academic “experts” make such claims all the time. Under the circumstances, if one of them says that this behavior is morally good, and that behavior is morally unethical, it begs the question of why? Logically, the only possible answer must be that the one conforms to their personal moral reference frame, and the other violates it. Under the circumstances one might point out that morality only exists because it happened to enhance the odds that the responsible genes would survive and reproduce, albeit in an environment radically different than the one we live in now. One might then ask, “How does the ‘bad’ thing in question diminish the chances that you will reproduce?”, or “How does the ‘good’ thing in question enhance the odds that you will survive?”

Of course, if one actually asked such questions, one would be met with looks of blank incomprehension. When it comes to morality, academics are just like everyone else. They behave the way they do because it feels good. They act that way because they are inclined by their emotions to act that way. They don’t presume to analyze their behavior any more deeply than that.

I recently read a book that is an excellent example of what I’ve written above. Entitled “A Natural History of Human Morality,” by Michael Tomasello, it claims to be about the evolution of human morality, which is described as “a uniquely human version of cooperation.” The book relentlessly emphasizes what the author imagines to be the “good” aspects of human moral behavior, and glosses over the “bad.” Improbable as it seems, there is nothing in the book to suggest that an evolved trait like morality might not promote the same outcome in the environment of today as it did 100,000 years ago. All that has been neatly taken care of by “gene-culture co-evolution.” We can look forward to a future where our innate altruism has won the day, and mankind lives happily ever after. It goes without saying that the prominent ingroup/outgroup aspect of our behavior is glossed over in spite of its rather too obvious manifestation, for example, in the bitter hatred and contempt of garden variety academics for Trump and all his supporters. Presumably, the future altruistic utopia must await the “liquidation of the Deplorables as a class,” to paraphrase Comrade Stalin.

One need only read the “Conclusion” of this brief book to dispel any doubt about the author’s firm faith in objective Good, existing somewhat incongruously in his mind with his equally firm but logically completely incompatible belief that morality is an evolved behavior. Ingroup/outgroup behavior is certainly mentioned, but is ascribed to such “objective evils” as colonialism:

In addition, there are many other conflicts between different ethnic groups that for various reasons (quite often involving outside influences, e.g., colonialism) have been forced to coexist under the same political umbrella. These are again instances of in-group/out-group conflicts, but again it is almost certain that those involved in them are doing many moral things with their compatriots on a daily basis. And despite all this, it is still the case that warlike conflicts, as well as many other types of violence, are historically on the wane. (Pinker, 2011).

Here one might ask the author what on earth he means by a “moral thing” if there is no such thing as objective Good. Is not loyalty to one’s group and defense of it against evil outsiders a “moral thing?” We learn that the equalist dogmas currently prevailing in academia also belong in the class of “objective Goods.” For example, according to the author,

A final criticism of too much rosiness is that we have posited a sense of equivalence among persons as foundational to human morality. Those who are used to thinking in terms of recorded human history will point out that it is only with the Enlightenment that social theorists in Western societies began promoting the idea of all individuals as in some sense equal, with equal rights. This is of course true in terms of explicit political thinking about the social contract after the rise of civil societies in the past ten thousand years. But the hunter-gatherer societies that existed for the immediately preceding period – for more than ten times that long – were by all indications highly egalitarian (Boehm, 1999).

Where to begin? In the first place, nature does not recognize any objective standard of “rosiness.” However, the author does not qualify the first sentence in the above quote by noting that he is only referring to his own personal moral standards when he claims that “equivalence among persons” is “rosy.” It is stated as an objective fact. Violence may or may not be declining in modern human societies, but no explanation is given for that trend one way or another in terms of evolved human behavioral traits as manifested in modern societies, and, again, there is no objective reason to claim that this development is “rosy” or “not rosy.” It is, of course, just another statement of one of the author’s personal subjective preferences stated as an “objective Good.” It is also one which can quickly become an anachronism with a push of the nuclear button. Nature doesn’t care in the least whether humans are violent or not. As far as equalist dogmas go, one is treading on thin ice with the claim that hunter-gatherer societies “were by all indications highly egalitarian.” They were only “highly egalitarian” according to safely orthodox academics whose evidence for making such claims is questionable, to put it mildly. As we saw, for example, in the case of Napoleon Chagnon, anyone who dares to question such “scientific findings” can expect to be subjected to furious attacks. The author apparently hasn’t noticed. Finally, we read,

No, it is a miracle that we are moral, and it did not have to be that way. It just so happens that, on the whole, those of us who made mostly moral decisions most of the time had more babies. And so, again, we should simply marvel and celebrate the fact that, mirabile dictu (and Nietzsche notwithstanding), morality appears to be somehow good for our species, our cultures, and ourselves – at least so far.

Is it really necessary for me to point out how and where the author refers to “good” as if it were an objective thing in this paragraph? When the author says “we are moral,” he means that we act in a way that is objectively good. He says we should all “marvel and celebrate the fact,” a statement that would be completely irrational if he were only stating a personal, subjective preference. What possible reason could the rest of us have for celebrating his interpretation of what his personal emotions are trying to tell him? Morality could not be unequivocally good for our species unless there were an unequivocal, that is, objective good. No such object exists.  As far as babies are concerned, there is today a demonstrable lack of them among the “good” in the author’s ingroup. I suggest he travel to Utah or Idaho, and note that the opposite is true of the Mormons, a different ingroup that is presumably “not so good” from his point of view.

I note in passing the fashion among modern academics to take passing slaps at Nietzsche, a philosopher who most of them don’t even begin to understand, who in fact can’t be understood outside of the context of his times, and who was anything but “amoral.” His sin was apparently disagreeing with them about what is “good”.

In short, the author is similar to every other modern academic intellectual I’m aware of in that, regardless of what he claims about the nature of morality, he behaves and speaks as if good and evil were objective things. Why is this important? Look around! The author and others like him have virtually complete control over the “moral landscape” as it exists in academia, social and legacy media, the entertainment industry, and among our current rulers. They present their personal moral prejudices as if there were some kind of objective authority and legitimacy behind them, when in fact there is none whatsoever. Based on this false assumption of authority, they are in the habit of denouncing and attacking anyone who disagrees with them. Do you like to be denounced and pushed around? Attacks on others based on a false assumption of moral authority are certainly irrational, but there is nothing objectively “bad” about them. I simply happen to have a personal aversion to them. That’s why I persist in pointing out the lack of legitimacy and authority for such attacks by those making them. Do you have an aversion to being pushed around as well? If so, I suggest you do the same.

Corona Comments

There are no objective oughts, no objective goods, no objective values, and no objective moral virtues. That is a simple statement of fact, and implies nothing whatsoever regarding how we ought to behave. Facts bear no implications about what we should do, except as means to an end. We must decide for ourselves what ends to seek. Objective facts may then inform us what we “should” do if we want to achieve the goals we set for ourselves.
Whatever the goals we set for ourselves happen to be, in large measure if not totally, they are a response to our “nature”; predispositions that are as much innate as our arms and legs. These predispositions are similar but not identical among human individuals, and they exist by virtue of natural selection. In other words, at some point and in some environment, they promoted the survival and reproduction of our ancestors. It cannot be assumed that their influence on our behavior will have that result in the very different environment most of us live in today.

Our nature does not determine our behavior, in the sense that it does not dictate what we must do in this or that situation. Rather, it inclines us to act in some ways, and not in others. It is fundamentally emotional, in humans as well as in other animals. We happen to have very large brains, and so can ponder over what our emotions are trying to tell us. We can reason about how we ought to respond to them. However, our reason is far from infallible. As the reasoning process becomes more complex, the outcome regarding what we “ought” to do will vary increasingly among individuals. This is doubly true by virtue of the fact that most individuals respond to their emotions blindly, never considering or taking into account why those emotions exist to begin with.

The above is illustrated by the response of our societies to the spread of COVID-19. The situation is anomalous, in that few of us have experienced anything like it. As a result, an appropriate response to it is not neatly packaged among our preferred or habitual responses to everyday occurrences. One result of this is that we find unusual differences of opinion about how we should react to the virus, even among those whose ideology, whether “liberal” or “conservative,” was formerly a reliable predicter of what their response to a given situation would be. Two factions have formed; those who tend to agree that we ought to take extreme measures to control the spread of the virus, and those who tend to believe that this “cure” is worse than the disease. At the moment the former faction has the upper hand, although the latter hasn’t been silenced completely.

Both factions present their arguments as if they are defending an objective truth. In fact, that is impossible, because objective “oughts” do not exist. What they are really defending is something they want, or value, and what they want or value represents their response to emotions that exist because they evolved. That statement applies not just to our response to a virus, but to every other form of conscious human behavior.

Emotional responses are bound to vary to some extent across populations that have been widely separated by time and space, but they tend to be quite similar, as one would expect of traits that happen to promote survival in a given species. Fear and avoidance of death is one trait almost all of us have in common. The emotional root cause of this fear probably hasn’t changed much, but in creatures with large brains such as ourselves, our behavior isn’t rigidly determined by our genes. We think about what our emotions are trying to tell us, and how we should behave in response. Needless to say, we don’t always all come to the same conclusions, regardless of how similar the underlying emotions happen to be.

In the modern human societies that exist in western Europe and North America, fear of death may well be a greater motivator than ever before. We have few children, and can reasonably expect that those children will survive to adulthood. That was not the case in societies that are more typical of our past, where a large fraction of children didn’t survive past their first few years. Death was not exactly welcomed, but we were more likely to accept it as a matter of course. Now we are more inclined to treat it as an unmitigated calamity, and one that must be staved off as long as possible at all costs. In the case of the virus, it almost seems some of us believe they will be immortal if only they can avoid catching it. Under the circumstances, such drastic steps as shutting down complex modern economies appear to be completely rational. We hand wave away any negative affect this may have on our own and future generations by simply assuming that the global economy will quickly recover afterwards. If we follow the chain of logic that is used to justify this behavior to its ultimate source, we will always find an emotion. The emotion is followed blindly, without regard for the reason it exists to begin with. That reason is that it once enhanced the odds of survival and reproduction of the genes that give rise to it. The question of whether it will have the same result if blindly reacted to in a completely different environment is treated as if it were entirely irrelevant.

In the case of the virus, our innate fear of death has triumphed over all other emotions. We don’t take into account the fact that, while that fear exists for a reason, the programmed death of our physical bodies and consciousness occurs for exactly the same reason. Our fear of death and our programmed death both promote the survival of our genes. Our genes don’t protect us from death indefinitely. Rather, they insure that we will die, but at a time that is optimum for insuring that they will not die. They have been around, in different forms but in an unbroken chain, for more than two billion years. For all practical purposes, they are potentially immortal. I happen to share the goal of my genes. That goal is no more intrinsically good or virtuous than someone else’s goal to accomplish the opposite. However, it does seem to me to have the virtue of being in harmony with the reasons I exist to begin with, and to be formed in full awareness of why the emotions that motivate it exist to begin with as well.

It does not seem “better” to me to be blindly blown about by the shifting winds of my emotions in a completely different environment than the one in which they evolved. The blind fear of death can be and often is trumped by an equally blind response to other emotions. Consider, for example, such slogans as “Death before dishonor,” “Give me liberty or give me death,” and “A fate worse than death.” Those who coined these slogans and those who were moved by them were no hypocrites. In the past we can find myriad examples of such individuals laying down their lives in defense of their principles. These principles were based on other innate emotions than fear of death, perhaps including hatred of the outgroup, or territoriality, or the struggle for status. Thus, while emotions are the basis of all our actions, they can motivate goals that are diametrically opposed to each other in different situations. I merely suggest that, instead of reacting to them blindly, we may find it useful to consider why they exist to begin with. That seems to me particularly true in the case of events as profound as global pandemics.

Morality: “What you do speaks so loudly that I cannot hear what you say.”

The Emerson quote in my title is certainly true in the case of morality. In fact, that’s one of the most important themes of this blog. Michael Huemer put it very well in his “Ethical Intuitionism,” the book I discussed in my last post. As he puts it,

I recently surveyed a class of about forty undergraduates on the subject (of morality, ed.). After explaining the terms “subjective” and “objective”, I asked how many of them believed that “morality is subjective”. Every single person in the room raised their hands, save two – those two were myself and my graduate student teaching assistant. This is all the more remarkable for the fact that it is usually all but impossible to attain universal agreement, in a philosophy class, on anything…

and

None of this seems to stop anyone – whether students, professors, or other intellectuals – from making moral judgments, arguing about what the correct moral views are, or trying to get others to obey the correct moral principles. Even those who declare morality an illusion will often proceed to hold forth on the wrongness of the war in Iraq, or of human cloning, or at least of their boyfriend’s cheating on them. And they seem to expect their arguments to be taken as reasons for other people to act in certain ways. This strikes me as odd. If I thought that the giant rabbit standing in the corner of the room was a hallucination, I don’t think I would hold forth in public about what his favorite food was, plan my actions around his schedule, or expect others to alter their behavior in the light of my claims about him.

How true! And yet I am not aware of a single exception to the behavior Huemer describes among self-described “subjective moralists.” I know of not a single one of them who doesn’t hold forth on what we “ought” to do, or what it is our “moral duty” to do, or how they consider this person morally obnoxious, and that person a paragon of moral virtue. One constantly finds them virtue signaling to demonstrate how “good” they are according to the standards of whatever version of morality currently happens to be fashionable in their ingroup. This certainly seems “odd” on the face of it, because it’s so obviously irrational. However, it’s not really that odd. We greatly overrate the intelligence of our species. To the extent that we reason at all, we often merely rationalize our responses to powerful emotions. Moral emotions are among the most powerful of all.

I’ve certainly devoted a lot of effort to making the case for moral subjectivism, and exploring the origins of morality in emotional predispositions that exist by virtue of natural selection. However, it’s at least as important to point out that these conclusions about morality have consequences. Morality is by no means just about regulating how we decide to behave as individuals. The assumption of a right to dictate behavior to others is an intrinsic element of human morality. As Huemer puts it, we invariably “expect others to alter their behavior” in light of our moral claims. And yet one needn’t know anything about Darwin to realize that no such right exists. When someone holds forth on how others must act to be “good,” or denounces others as “immoral,” one need merely ask oneself the question, “On what authority do they make these claims?” No such authority exists.

If I am right, and morality is a manifestation of emotions that themselves exist by virtue of natural selection, then the assumption of such “rights” and “authorities” must have promoted our survival in the context of the environment that existed when the behavior in question evolved. At the time we lived in small groups of individuals who were all more or less genetically related to us. There would have been little if any disagreement about the moral rules we lived by. Obedience to those rules would have been to the advantage of all the individuals in the group. Assumption of a right to remind others of the moral rules and to insist that they obey them would have promoted not only their survival, but ours as well.

Fast forward to the present. We still behave in the same old way, because it is our nature to behave in that way. However, the consequences are no longer the same. Wherever we turn, from books to movies to the very commercials on TV, we are subjected to a barrage of “oughts.” Everywhere we turn we find furious people attempting to dictate behavior to us and everyone else based on whatever flavor of morality they happen to prefer. They are driven by emotions, and are completely blind to the reasons the emotions exist. In their blindness, they rationalize their demands for obedience. They claim that they are serving some noble cause, whether it be human flourishing, or the workers paradise, or the triumph of some national or ethnic ingroup. It doesn’t really matter, because it’s all self-deception. Before the Nazis took over in Germany, party members would become Communists and vice versa at the drop of a hat. Today we find committed “progressives” casting loving glances at radical Islamists for the same reasons. They quickly recognize another very effective, if different, way to scratch the same moral itch that afflicts them.

As far as Mother Nature is concerned, these people are really telling us something completely different. Even though they don’t realize it, they are saying, “You must behave in a way that promotes my survival and reproduction. It will not promote your survival and reproduction, and won’t benefit you in any other way, either. In fact, it will probably harm you. In spite of that, if you don’t obey me, you are bad. To become good, you must do as I say.” Back in the day that might have made sense. The only people you would have known and interacted with would have been those in your little ingroup, and you would have been related to all of them. Promoting their survival and reproduction would likely have promoted your own as well. Today, not only do their demands not promote your survival and reproduction, they generally do not promote their own survival and reproduction, either. It is hardly a given that actions that have a certain result in one social environment will accomplish the same thing in one that is radically different. It should come as no surprise if they accomplish exactly the opposite.

I can’t tell you that you are bad if you choose to obey the emotionally motivated and arbitrary demands of people that you obey them, even if you are unrelated to them and your obedience will be of no advantage to you whatsoever. I can, however, conclude that you have strange goals in life. Perhaps you simply like to be dominated by others, and your goal is then to die and become extinct. If that is your goal, so be it. I have different goals. My goals are my own survival and reproduction, and the survival of biological life in general. I have those goals, not because they are intrinsically morally good, but because they seem to me compatible with the reasons I and the rest of the life on this planet exist to begin with. What has happened here is awesome. Look at yourself! You, an incredibly complex, intelligent being, have come into being from inanimate matter through a wildly improbable process of evolution. It may be so improbable that we are alone in the universe. The type of a person who can be aware of all that and respond, “It doesn’t matter. Who cares if we all go extinct?” is incomprehensible to me. All I can say is, I’m not like that. It does matter to me. For that reason, I reject the emotionally motivated demands of others that they be allowed to dictate behavior to me, and dismiss their absurd claims that they are acting in the interest of some higher, objective “good” out of hand. I choose to act in ways that are compatible with my own goals in life.

I submit that if you conclude that morality is, indeed, subjective, but treat the fact as if it were of mere academic interest, and go right on playing the same moralistic games as everyone else, you have completely missed the point. That, however, is precisely what we see in the case of every “subjective moralist” I’m aware of.  I personally would prefer that we all see morality for the evolved and potentially highly dangerous phenomenon it actually is. However, in view of the above, for all practical purposes universal, behavior, that isn’t about to happen anytime soon. Virtually every member of our “intelligent” species continues in thrall to emotionally spawned illusions. I can only suggest that, as individuals, we be acutely aware of our situation, whatever our goals happen to be, and act to defend ourselves and whatever we happen to find valuable in life as best we can.

Objective Morality: The “Ethical Intuitionism” Gambit

Does it make any difference whether morality is objective or subjective? I think the answer to that question is certainly “yes”. If morality is objective, than it is our duty to obey the moral law no matter what. If we don’t, we are bad by definition. To the extent that other people understand the moral law better than we do, or are more virtuous than we are, they have an indubitable right to dictate to us how we ought to behave, and to vilify us if we don’t do as they tell us. If, on the other hand, morality is subjective, then it must be an artifact of natural selection. It could not be otherwise with emotionally motivated behavioral traits that clearly have a profound influence on whether we will survive or not. At least it could not be otherwise assuming there is no God, and that Hume and others before him were right in claiming that morality is not accessible via pure reason. For reasons I have outlined elsewhere, I think both of these assumptions are true. If morality is, indeed, an artifact of natural selection, then it follows that it can hardly be blindly assumed that what promoted our survival in the past when the traits in question evolved will continue to promote our survival in the present. In fact, it is quite possible that some of them have become dangerous in the environment we live in now. In that case no one has a right to dictate how we ought or ought not to behave based on their subjective version of morality. Instead of helpfully informing us what we need to do to be good, such people may actually pose a threat to us, to the extent that we value our own survival. These are only a few of the issues that depend on the answer to this question.

As my readers know, I believe that morality is subjective. Many philosophers disagree with me. One such is Prof. Michael Huemer of the University of Colorado. Huemer, who has a blog by the name of Fake Nous, supports a version of objective morality known as ethical intuitionism, which is also the title of a book he has written about the subject. His claim is that we are “justified” in assuming there is an objective moral law because it “appears” to our intuition, and we should trust appearances absent convincing evidence that they are wrong. I think that, in examining this version of objective morality, it will be possible to expose some of the weaknesses common to them all.

According to Huemer, the morality object does not exist in the realm of objects that can “appear” to our usual five senses, either directly or via scientific instruments. Of course, this must be true, as no one has yet succeeded in snagging a good or evil object and putting it on display in a museum for the rest of us to admire. However, things in the extrasensory realm where the morality object exists do appear to our intuition. According to Huemer, that’s how we recognize its reality.

Of course, an obvious objection to Huemer’s claim that we are as justified in believing in objects that “appear” to our intuitions as in objects that appear to our senses is that claims based on such “appearances” are not falsifiable by the conventional scientific method of checking them via repeatable experiments.  However, setting that aside for the moment, let’s examine the credibility of this claim starting from the very beginning. For all practical purposes, the very beginning was the Big Bang. Physicists have given us plausible explanations of how everything we can detect in the observable universe came into existence in the aftermath of the Big Bang. I can accept the existence of quarks, photons, and quantum fields, because their “appearance” has been confirmed many times over in repeatable experiments, and they are accessible to my senses, either directly, or via scientific instruments. However, I find it incredible that this cataclysmic event also spit out a moral law object, which now somehow permeates all space. I am not at all trying to be funny here. If this thing the philosophers refer to exists, there must be some explanation of how it came to exist. What is it?

However, let us assume for the moment that the moral law object did somehow come into existence. Presumably this must have been before the evolution of human beings, else we couldn’t possibly have evolved the capacity to detect it with our intuitions. Absent some other plausible path to the existence in our brains of something as sophisticated as an “intuition” sense capable of enabling us to detect the moral law object, this ability must necessarily be a result of natural selection. Of course, natural selection doesn’t automatically choose the Good. It chooses whatever promotes our survival. If Huemer is right, then we must have somehow acquired, not only the ability to detect the moral law object via intuition, but virtually at the same time a predisposition to act in accordance with the moral law. By a wonderful coincidence, it also just so happened that acting in this way promoted the survival of creatures such as ourselves, although it would more likely have resulted in the immediate demise of other life forms. Darwin mentions bees, for example.

Our eyes and ears have taken hundreds of millions of years to evolve. How is it that a “sense” capable of detecting the moral law object evolved so quickly? It couldn’t have happened in creatures less intelligent than ourselves, because they have no morality, at least as it is described by Huemer, nor any need for an intuition capable of detecting it. The initial appearance of this “sense” in our species and its subsequent evolution to such a state of perfection must have happened rapidly indeed.

Huemer dismisses natural selection as an explanation of subjective morality because, in his words, it is “not impressive.” As can be seen above, however, he cannot simply hand wave natural selection out of existence. He claims we possess an intuition capable of detecting morality objects. How did we acquire this intuition absent natural selection? If Huemer wants to claim that God did it, well and good, we can debate the existence of God. However, I doubt he wants to go there. There is no mention of God in his book. Absent God, what other path to the acquisition of such a complex ability exists, other than natural selection? Huemer will have to be “impressed” by natural selection at some point, whether he likes it or not.

Assuming Darwin was right about natural selection, isn’t it simpler and more rational to accept that innate behavior, including the predispositions that give rise to morality, evolved directly because it happened to promote survival, resulting in our associating “good” with behavior that promoted our survival and “bad” with behavior that didn’t? The alternative proposed by Huemer is that we first evolved the ability to detect the moral law, only then followed by the evolution of awareness that the moral law was trying to get us to do something followed by a predisposition to believe it was “good” to follow the moral law and “bad” not to follow it, along with the remarkable coincidence that all this promoted our survival. Does this sound even remotely plausible to you? Then, to use one of the author’s favorite clichés, I have some bridges to sell you.

I submit that every version of objective morality that doesn’t rely on the intervention of supernatural beings suffers from the same implausibility as Huemer’s system, for more or less the same reasons. That’s why I believe that morality is subjective. Huemer notes in his book that I am hardly alone in this regard. There are legions of people who describe themselves as subjective moralists. However, as he also correctly points out, it doesn’t make any difference. When it comes to their actual moral behavior, they act in ways that are inexplicable absent the implied assumption of objective morality. I know of not a single exception to this rule among philosophers, scientists, and intellectuals of note. Every one of them treats their idiosyncratic moral judgments as if they automatically apply to others without so much as blinking an eye. That is actually a major theme of this blog. However, I’ve rambled on long enough, and will take up the matter in my next post.

E. O. Wilson’s Farewell Letter

There are but 125 very sparsely filled pages in Genesis, E. O. Wilson’s latest. The book is really little more than a pamphlet. The few reviews one finds online are dismissive in their brevity. Perhaps it’s best described as a farewell letter from the grand old man. If so, the loss will be great. I know of no one who can fill his shoes. Wilson is an independent, courageous thinker who is refreshingly free of the now ubiquitous habit of larding his books with virtue signaling to his academic tribe. He can also occasionally be quite blunt. For example, in Genesis,

The following can be posed with near certainty. Every part of the human body and mind has a physical base obedient to the laws of physics and chemistry. And all of it, so far as we can tell by continuing scientific examination, originated through evolution by natural selection.

No mealy-mouthed nonsense there about “spandrels,” or “exaptations.” Wilson has always been forthright about insisting on the obvious. Continue reading “E. O. Wilson’s Farewell Letter”

Has It Ever Occurred To You That None Of Us Are Acting Rationally?

Do you imagine that you are acting for the good of all mankind? You are delusional. What is your actual goal when you imagine you are acting for the good of all mankind? Maximization of human happiness? Maximization of the rate at which our species as a whole reproduces? Complete elimination of our species? All of these mutually exclusive goals are deemed by some to be for the “good of all mankind.” How is that possible if there really is such a thing as “the good of all mankind?” The answer is that there is no such thing, for the simple reason that there is no such thing as good, unless one is speaking of a subjective impression.

Look, just stop arguing with me in your mind for a moment and try a thought experiment. Imagine that what I’ve said above about good – that it is merely a subjective impression – is true. In that case, how can we account for the existence of this subjective impression, this overpowering belief that some things are good and other things are evil? It must exist for the same reason that all of our other behavioral predispositions and traits exist – by virtue of natural selection, the same process that accounts for our very existence to begin with. In that case, these subjective impressions, these overpowering beliefs, must exist because, in the environment in which they evolved, they enhanced the odds that the responsible genes would survive and reproduce. How, then, is it possible for us to imagine that our goal is “the good of all mankind.” Natural selection does not operate at the level of “all mankind.” It operates at the level of the individual and, perhaps, at the level of small groups. If our goal is to act for “the good of the species,” we can only conclude that the behavioral predispositions responsible for this desire have become “dysfunctional,” in the sense that they are no longer likely to promote the survival of the responsible genes. The most plausible reason they have become “dysfunctional” is the fact that they exist in the context of a radically changed environment.

This has some obvious implications as far as the rationality of our behavior is concerned. Try following the reasons you imagine you’re doing what you do down through the accumulated “rational” muck to the emotional bedrock where they originate. You can string as many reasons together as you want, one following the other, and all perfectly rational, but eventually the chain of reasons must lead back to the origin of them all. That origin cannot be the “good in itself,” because such an object does not exist. It is imaginary. In fact, the bedrock we are seeking consists of behavioral predispositions that exist because they evolved. As the result of a natural process, they cannot possibly be “rational,” in the sense of having some deeper purpose or meaning more fundamental than themselves. It is evident that these behavioral traits exist because, at least at some point in time and in some environment, they enhanced the odds that the individuals possessing these traits would survive and reproduce. That, however, is not their purpose, or their function, because there was no one around to assign them a purpose or function. They have no purpose or function. They simply are.

That’s what I mean when I say that none of us acts rationally. The sun does not act rationally when it melts solid objects that happen to fall into it. It does not have the purpose or goal of melting them. It simply does. The ocean does not act rationally when it drowns air breathing creatures that are unfortunate enough to sink beneath its surface. Millions of creatures have drowned in the ocean, but the ocean didn’t do it on purpose, nor did it have a goal in doing so. In the same sense, our behavioral traits do not have a goal or purpose when they motivate us to act in one way or another. Just as it is a fact of nature that the sun melts solid objects, and the ocean drowns land creatures, it is a fact of nature that we are motivated to do some things, and avoid others. That is what I mean when I say that our behavior is irrational. I don’t mean that it can’t be explained. I do mean that it has no underlying purpose or goal for doing what it does. Goals and purposes are things we assign to ourselves. They cannot be distilled out of the natural world as independent objects or things in themselves.

Consider what this implies when it comes to all the utopian schemes that have ever been concocted for our “benefit” over the millennia. A goal that many of these schemes have had in common is “moral progress.” It is one of the more prominent absurdities of our day that even those among us who are most confident that Darwin was right, and who have admitted that there is a connection between morality and our innate behavioral predispositions, and who also realize and have often stated publicly that morality is subjective, nevertheless embrace this goal of “moral progress.” This begs the question, “Progress towards what?” Assuming one realizes and has accepted the fact that morality is subjective, it can’t be progress towards any objective Good, existing independently of what anyone thinks about it. It must, then, be progress towards something going on in conscious minds. However, as noted above, conscious minds are a fact of nature, existing by virtue of natural processes that have no function and have no goal. They simply are. Furthermore, our conscious minds are not somehow connected all across the planet in some mystical collective. They all exist independently of each other. They include predispositions that motivate the individuals to whom they belong to have desires and goals. However, those desires and goals cannot possibly exist by virtue of the fact that they benefit all mankind. They exist by virtue of the fact that they enhanced the odds that the responsible genetic material would survive and reproduce. They were selected at the level of the individual, and perhaps of small groups. They were definitely not selected by virtue of any beneficial effect on all mankind.

In other words, when one speaks of “moral progress,” what one is in reality speaking of is progress towards satisfying the whims of some individual. The reason for the existence of these whims has nothing to do with the welfare of all mankind. To the extent that the individual imagines they have some such connection, the whims have become “dysfunctional,” in the sense that they have been redirected towards a goal that is disconnected from the reasons they exist to begin with. Belief in “moral progress,” then, amounts to a blind emotional response to innate whims on the part of individuals who have managed to profoundly delude themselves about exactly what it is they’re up to. The problem, of course, is that they’re not the only ones affected by their delusion. Morality is always aimed at others. They insist that everyone else on the planet must respect their delusion, and allow it to dictate how those others should or should not behave.

This fundamental irrationality applies not just to morality, but to every other aspect of human behavior. Whether it’s a matter of wanting to be “good,” or of “serving mankind,” or accumulating wealth, or having sex, or striving for “success” and recognition, we are never motivated by reason. We are motivated by whims, although we certainly can and do reason about what the whims are trying to tell us. This process of reasoning about whims can result in a bewildering variety of conclusions, most of which have nothing to do with the reasons the whims exist to begin with. You might say that our brains have evolved too quickly. Our innate behavioral baggage has not kept up, and remains appropriate only to environments and forms of society that most of us left behind thousands of years ago. We continue to blindly respond to our emotions without understanding why they exist, pursuing goals that have nothing to do with the reasons they exist. In effect, we are living in an insane asylum.

I am not suggesting that we all stop having goals and aspirations. Life would be extremely boring without them, and they can be just as noble as we please, at least from our own point of view. From my point of view, the fact that creatures like us can exist at all seems wildly improbable, wonderful, and sublime. For all we know, the life we are a part of may exist on only one of the trillions of planets in our universe. I personally deem it precious, and one of my personal goals is that it be preserved. Others may have different goals. I merely suggest that, regardless of what they are, we keep in mind what motivates us to seek them in the first place. I personally would prefer that we avoid botching the wildly improbable, wonderful, and sublime experiment of nature that is us by failing to understand ourselves.

Ingroups and Outgroups and Sir Arthur Keith – Adventures in the Bowdlerization of History

There is no more important aspect of human nature than our tendency to perceive others in terms of ingroups and outgroups. Without an awareness of its existence and its power it is impossible to understand either out history or many of the critical events that are happening around us today. A trait that probably existed in our ancestors millions of years ago, it evolved because it promoted our survival when our environment and way of life were radically different from what they are now. In the context of current human technologies and societies, it often appears to have become wildly dysfunctional. We can distinguish ingroup from outgroup based on the subtlest of differences. That worked fine when we all lived in small groups of hunter-gatherers. The outgroup was always just the next group over. Today the same mental equipment for identifying the outgroup has resulted in endless confusion and, in many cases, disaster. The only way out lies in self-understanding, but as a species we exhibit an incorrigible resistance to knowing ourselves.

In my last post I commented on the foibles of an ingroup of intellectuals whose “territory” was defined by ideology. I’m sure they all believed their behavior was entirely rational, but they had no clue what was going on as they reacted to a “turncoat” and “heretic” in the same way that ingroups have done for eons. Had they read a seminal book by Sir Arthur Keith entitled A New Theory of Human Evolution, they might have had at least an inkling about the real motivation of their behavior. Published in 1948, the book was of critical importance, not just because it addressed the question of ingroups and outgroups, but because of Keith’s sure feel for the aspects of human behavior that really matter, and for his forthright and undaunted insistence on the existence and importance of innate human nature. He was certainly not infallible. What scientist is? He believed the Piltdown skull was real until it was finally proved a hoax just before he died. Some of what he had to say about human behavior has stood the test of time and some hasn’t. However, his hypotheses about ingroups and outgroups definitely belong in the former category, along with many others. There is no question that they were closer to the truth than the Blank Slate dogmas that already served as holy writ for most of the so-called behavioral scientists of the day.

Today there are few original copies of his book around, although some are offered at Amazon as I write this. However, it is available online at archive.org, and reprints are available at Alibris.com and elsewhere. It is a must read if you interested in human behavior, and even more so if you are interested in the history of the behavioral sciences in general and the Blank Slate in particular. Unfortunately, most of the accounts of that history that have appeared in the last 50 years or so are largely fairy tales, concocted either to deny or “embellish” the reality that the Blank Slate was the greatest scientific catastrophe of all time. If you want to know what really happened, there is no alternative to consulting the source material yourself.  One of the biggest fairy tales is that the man who played the greatest single role in demolishing the Blank Slate, Robert Ardrey, was “totally and utterly wrong.” In fact, Ardrey was “totally and utterly right” about the main theme of all his books; that human nature is both real and important. He insisted on that truth in the teeth of the Blank Slate lies that had been swallowed by virtually every “behavioral scientist” of his day.

Ardrey had an uncanny ability to ferret out scientists whose work actually did matter. Sir Arthur Keith was no exception. What he had to say about Keith and his take on ingroup/outgroup behavior was far more eloquent than anything I could add. For example,

In his last two books, Essays on Human Evolution in 1946 and A New Theory of Human Evolution in 1948, Keith took the final, remorseless step which his thinking had made inevitable. Conscience, he affirmed is simply that human mechanism dictating allegiance to the dual code. Those who assert that conscience is inborn are therefore correct. But just how far does conscience compel our actions in such an ultimate direction as that of the brotherhood of man? Not far. Conscience is the instrument of the group.

Human nature has a dual constitution; to hate as well as to love are parts of it; and conscience may enforce hate as a duty just as it enforces the duty of love. Conscience has a two-fold role in the soldier: it is his duty to save and protect his own people and equally his duty to destroy their enemies… Thus, conscience serves both codes of group behavior: it gives sanction to practices of the code of enmity as well as of the code of amity.

These were Keith’s last words on the subject. If the grand old man had any noteworthy capacities for self-delusion, they escape the eye. And when he died a few years later, at the age of ninety, with him ended truth’s brief history. His thoughts by then were overwhelmed by the new romanticism (the Blank Slate, ed.) when falsehood came to flower: his sentiments were condemned by that academic monopoly which substituted high-mindedness for the higher learning. And as for almost twenty years no one followed C. R. Carpenter (a primatologist who published some “inconvenient truths” about the behavior of monkeys and apes in the field, anticipating the revelations of Goodall and others, ed.) into the rain forest, so for almost twenty years none has followed Sir Arthur Keith into the jungle of noble intentions.

Beautifully said by the great nemesis of the Blank Slate. Ardrey had much else to say about both Keith and the history of hypotheses about ingroup/outgroup behavior in Chapter 8, “The Amity-Enmity Complex” of his The Territorial Imperative. If you’re looking for source material on the history of the Blank Slate, Ardrey’s four books on human nature wouldn’t be a bad place to start. They’re certainly more accurate than Pinker’s fanciful “history” of the affair. Keith himself was certainly aware of Blank Slate ideologues and their “academic monopoly.” However, he had a naïve faith that, if he only told the truth, he would eventually be vindicated. A hint about the extent to which that faith was realized can be gleaned by perusing the Wiki entry about him, which dismisses him into the realm of unpersons with the usual hackneyed claim of the pathologically pious that he was a “racist,” along with a gleeful notice that he was taken in by the Piltdown skull.

When it comes to the bowdlerization of history, by all means, have a look at the Wiki entry on “Ingroups and outgroups” as well. The most shocking thing about it is the thought that its author might actually believe what he’s written. We learn, for example, that “The terminology was made popular by Henri Tajfel and colleagues during his work in formulating social identity theory.” One wonders whether to laugh or despair on reading such absurdities. The idea that the history of what Ardrey referred to as the “Amity-Enmity Complex” began with some inconsequential “study” done by a Polish psychologist back in 1971 is beyond ludicrous. That’s just one of the reasons why its important to read such important bits of source material as Keith’s book. He actually presents an accurate account of the history of this critical aspect of human behavior. For example,

In brief, I hold that from the very beginning of human evolution the conduct of every local group was regulated by two codes of morality, distinguished by Herbert Spencer as the “code of amity” and the “code of enmity.”

Spencer wrote extensively about the subject in his Principles of Ethics, which appeared in 1892, nearly 80 years before the subject “was made popular” in Tajfel’s “study.” Unfortunately, he also noted the fallacies behind the then fashionable versions of socialism in another of his books, and gave reasons that governments based on them would fail that were amply confirmed by the history of the next hundred years. For that, he was viciously condemned as a “Social Darwinist” by the socialist true believers. The moniker has stuck to this day, in spite of the fact that Spencer was never even a “Darwinist” to begin with. He certainly had his own theories of evolution, but they were much closer to Lamarckism than Darwinism. In any case, Keith continues,

As a result of group consciousness, which serves to bind the members of a community together and to separate the community from all others, “there arises,” to use the words of Professor Sumner, “a differentiation between ourselves – the ‘we’ group or ‘in’ group – and everybody else – the ‘out’ group.”

The passage Keith refers to appeared in Folkways, published by Prof. William Graham Sumner in 1906, also somewhat earlier than the good Prof. Tajfel’s study. Of course, studies by learned professors of psychology are not necessary to document ingroup/outgroup behavior. Just read a little history. Look around you. Can one really understand the furious hatred of Trump by so many highly educated academics and intellectuals absent a grasp of this aspect of human behavior? Are racism, anti-Semitism, religious bigotry, hatred of the “bourgeoisie” or other versions of the “class enemy,” or any of the other myriad versions of outgroup identification that have been documented in our history best understood as the acts of “evil” people, who apparently get up every morning wracking their brains to decide what bad deeds they can do that day, or are they better understood as manifestations of the type of innate behavior described by Prof. Keith? I personally lean towards the latter explanation. Given the incredibly destructive results of this aspect of our behavior, would it not be advisable for our “experts” in evolutionary psychology to devote a bit more attention to it, as opposed to the more abstruse types of sexual behavior by which they now seem to be so fascinated? No doubt it would annoy the hardcore Blank Slaters who still haunt academia, but on the other hand, it might actually be useful.

Sir Arthur had much more to say about the evolution of human nature, including that great tool of historical obfuscation, “group selection.” But that’s a matter best left to another day.

Robert Plomin’s “Blueprint”: The Reply of the Walking Dead

The significance of Robert Plomin’s Blueprint is not that every word therein is infallible. Some reviewers have questioned his assertions about the relative insignificance of the role that parents, schools, culture, and other environmental factors play in the outcome of our lives, and it seems to me the jury is still out on many of these issues. See, for example, the thoughtful review of Razib Khan in the National Review. What is significant about it is Plomin’s description of new and genuinely revolutionary experimental tools of rapidly increasing power and scope that have enabled us to confirm beyond any reasonable doubt that our DNA has a very significant influence on human behavior. In other words, there is such a thing as “human nature,” and it is important. This truth might see obvious today. It is also a fact, however, that this truth was successfully suppressed and denied for over half a century by the vast majority of the “scientists” who claimed to be experts on human behavior.

There is no guarantee that such scientific debacles are a thing of the past. Ideologues devoted to the quasi-religious faith that the truth must take a back seat to their equalist ideals are just as prevalent now as they were during the heyday of the Blank Slate. Indeed, they are at least as powerful now as they were then, and they would like nothing better than to breathe new life into the flat earth dogmas they once foisted on the behavioral sciences. Consider, for example, a review of Blueprint by Nathaniel Comfort entitled “Genetic determinism rides again,” that appeared in the prestigious journal Nature. The first paragraph reads as follows:

It’s never a good time for another bout of genetic determinism, but it’s hard to imagine a worse one than this. Social inequality gapes, exacerbated by climate change, driving hostility towards immigrants and flares of militant racism. At such a juncture, yet another expression of the discredited, simplistic idea that genes alone control human nature seems particularly insidious.

Can anyone with an ounce of common sense, not to mention the editors of a journal that purports to speak for “science,” read such a passage and conclude that the author will continue with a dispassionate review of the merits of the factual claims made in a popular science book? One wonders what on earth they were thinking. Apparently Gleichschaltung is sufficiently advanced at Nature that the editors have lost all sense of shame. Consider, for example, the hoary “genetic determinism” canard. A “genetic determinist” is a strawman invented more than 50 years ago by the Blank Slaters of old. These imaginary beings were supposed to believe that our behavior is rigidly programmed by “instincts.” I’ve searched diligently during the ensuing years, but have never turned up a genuine example of one of these unicorns. They are as mythical as witches, but the Blank Slaters never tire of repeating their hackneyed propaganda lines. It would be hard to “discredit” the “simplistic idea that genes alone control human nature” by virtue of the fact that no one ever made such a preposterous claim to begin with, and Plomin certainly wasn’t the first. Beyond that, what could possibly be the point of dragging in all the familiar dogmas of the “progressive” tribe? Apparently Nature would have us believe that scientific “truth” is to be determined by ideological litmus tests.

In the next paragraph Comfort supplies Plomin, a professor of behavior genetics, with the title “educational psychologist,” and sulks that his emphasis on chromosomal DNA leaves microbiologists, epigeneticists, RNA experts, and developmental biologists out in the cold. Seriously? Since when did these fields manage to hermetically seal themselves off from DNA and become “non-overlapping magisteria?” Do any microbiologists, epigeneticists, RNA experts or developmental biologists actually exist who consider DNA irrelevant to their field?

Comfort next makes the logically questionable claim that, because “Darwinism begat eugenics”, “Mendelism begat worse eugenics,” and medical genetics begat the claim that men with an XYY genotype were violent, therefore behavioral genetics must also “begat” progeny that are just as bad. QED

Genome-wide association (GWA) methods, the increasingly powerful tool described in Blueprint that has now put the finishing touches on the debunking of the Blank Slate, are dismissed as something that “lures scientists” because of its “promise of genetic explanations for complex traits, such as voting behavior or investment strategies.” How Comfort distills this “promise” out of anything that actually appears in the book is beyond me. One wonders if he ever actually read it. That suspicion is greatly strengthened when one reads the following paragraph:

A polygenic score is a correlation coefficient. A GWAS identifies single nucleotide polymorphisms (SNPs) in the DNA that correlate with the trait of interest. The SNPs are markers only. Although they might, in some cases, suggest genomic neighborhoods in which to search for genes that directly affect the trait, the polygenic score itself is in no sense causal. Plomin understands this and says so repeatedly in the book – yet contradicts himself several times by arguing that the scores are in fact, causal.

You have to hand it to Comfort, he can stuff a huge amount of disinformation into a small package. In the first place, the second and third sentences contradict each other. If SNPs are variations in the rungs of DNA that occur between individuals, they are not just markers, and they don’t just “suggest genomic neighborhoods in which to search for genes that directly affect the trait.” If they are reliable and replicable GWA hits, they are one of the actual points at which the trait is affected. Plomin most definitely does not “understand” that polygenic scores are in no sense causal, and nowhere does he say anything of the sort, far less “repeatedly.” What he does say is:

In contrast, correlations between a polygenic score and a trait can only be interpreted causally in one direction – from the polygenic score to the trait. For example, we have shown that the educational attainment polygenic score correlates with children’s reading ability. The correlation means that the inherited DNA differences captured by the polygenic score cause differences between children in their school achievement, in the sense that nothing in our brains, behavior, or environment can change inherited differences in DNA sequence.

I would be very interested to hear what Comfort finds “illogical” about that passage, and by virtue of what magical mental prestidigitations he proposes to demonstrate that the score is a “mere correlation.” Elsewhere we read,

Hereditarian books such as Charles Murray and Richard Herrnstein’s The Bell Curve (1994) and Nicholas Wade’s 2014 A Troublesome Inheritance (see N. Comfort Nature 513, 306–307; 2014) exploited their respective scientific and cultural moments, leveraging the cultural authority of science to advance a discredited, undemocratic agenda. Although Blueprint is cut from different ideological cloth, the consequences could be just as grave.

In fact, neither The Bell Curve nor A Troublesome Inheritance have ever been discredited, if by that term is meant being proved factually wrong. If books are “discredited” by how many ideological zealots begin foaming at the mouth on reading them, of course, it’s a different matter. Beyond that, if something is true, it does not become false by virtue of Comfort deeming it “undemocratic.” I could go on, but what’s the point? Suffice it to say that Comfort’s favorite “scientific authority” is Richard Lewontin, an obscurantist high priest of the Blank Slate if ever there was one, and author of Not in Our Genes.

I can understand the editors of Nature’s desire to virtue signal their loyalty to the prevailing politically correct fashions, but this “review” is truly abject. It isn’t that hard to find authors on the left of the political spectrum who can write a book review that is at least a notch above the level of tendentious ideological propaganda. See, for example, Kathryn Paige Harden’s review of Blueprint in the Spectator. Somehow she managed to write it without implying that Plomin is a Nazi in every second sentence.  I suggest that next time they look a little harder.

My initial post about Blueprint tended to emphasize the historical ramifications of the book in the context of the Blank Slate disaster. As a result, my description of the scientific substance of the book was very broad brush. However, there are many good reviews out there that cover that ground, expressing some of my own reservations about Plomin’s conclusions about the importance of environment in the process. See, for example, the excellent review by Razib Khan in the National Review linked above. As I mentioned in my earlier post, the book itself is only 188 pages long, so, by all means, read it.

Robert Plomin’s “Blueprint” – The Blank Slate and the Behavioral Genetics Insurgency

Robert Plomin‘s Blueprint is a must read. That would be true even if it were “merely” an account of recent stunning breakthroughs that have greatly expanded our understanding of the links between our DNA and behavior. However, beyond that it reveals an aspect of history that has been little appreciated to date; the guerilla warfare carried on by behavioral geneticists against the Blank Slate orthodoxy from a very early date. You might say the book is an account of the victorious end of that warfare. From now on those who deny the existence of heritable genetic effects on human behavior will self-identify as belonging to the same category as the more seedy televangelists, or even professors in university “studies” departments.

Let’s begin with the science.   We have long known by virtue of thousands of twin and adoption studies that many complex human traits, including psychological traits, are more or less heritable due to differences in DNA. These methods also enable us to come up with a ballpark estimate of the degree to which these traits are influenced by genetics. However, we have not been able until very recently to detect exactly what inherited differences in DNA sequences are actually responsible for the variations we see in these traits. That’s were the “revolution” in genetics described by Plomin comes in. It turns out that detecting these differences was to be a far more challenging task than optimistic scientists expected at first. As he put it,

When the hunt began twenty-five years ago everyone assumed we were after big game – a few genes of large effect that were mostly responsible for heritability. For example, for heritabilities of about 50 per cent, ten genes each accounting for 5 per cent of the variance would do the job. If the effects were this large, it would require a sample size of only 200 to have sufficient power to detect them.

This fond hope turned out to be wishful thinking. As noted in the book, some promising genes were studied, and some claims were occasionally made in the literature that a few such “magic” genes had been found. The result, according to Plomin, was a fiasco. The studies could not be replicated. It was clear by the turn of the century that a much broader approach would be necessary. This, however, would require the genotyping of tens of thousands of single-nucleotide polymorphisms, or SNPs (snips). A SNP is a change in a single one of the billions of rungs of the DNA ladder each of us carries. SNPs are one of the main reasons for differences in the DNA sequence among different human beings. To make matters worse, it was expected that sample sizes of a thousand or more individuals would have to be checked in this way to accumulate enough data to be statistically useful. At the time, such genome-wide association (GWA) studies would have been prohibitively expensive. Plomin notes that he attempted such an approach to find the DNA differences associated with intelligence, with the aid of a few shortcuts. He devoted two years to the study, only to be disappointed again. It was a second false start. Not a single DNA association with intelligence could be replicated.

Then, however, a major breakthrough began to make its appearance in the form of SNP chips.  According to Plomin, “These could “genotype many SNPs for an individual quickly and inexpensively. SNP chips triggered the explosion of genome-wide association studies.” He saw their promise immediately, and went back to work attempting to find SNP associations with intelligence. The result? A third false start. The chips available at the time were still too expensive, and could identify too few SNPs. Many other similar GWA studies failed miserably as well. Eventually, one did succeed, but there was a cloud within the silver lining. The effect size of the SNP associations found were all extremely small. Then things began to snowball. Chips were developed that could identify hundreds of thousands instead of just tens of thousands of SNPs, and sample sizes in the tens of thousands became feasible. Today, sample sizes can be in the hundreds of thousands. As a result of all this, revolutionary advances have been made in just the past few years. Numerous genome-wide significant hits have been found for a host of psychological traits. And now we know the reason why the initial studies were so disappointing. In Plomin’s words,

For complex traits, no genes have been found that account for 5 per cent of the variance, not even 0.5 per cent of the variance. The average effect sizes are in the order of 0.01 per cent of the variance, which means that thousands of SNP associations will be needed to account for heritabilities of 50 per cent… Thinking about so many SNPs with such small effects was a big jump from where we started twenty-five years ago. We now know for certain that heritability is caused by thousands of associations of incredibly small effect. Nonetheless, aggregating these associations in polygenic scores that combine the effects of tens of thousands of SNPs makes it possible to predict psychological traits such as depression, schizophrenia and school achievement.

In short, we now have a tool that, as I write this, is rapidly increasing in power, and that enables falsifiable predictions regarding many psychological traits based on DNA alone. As Plomin puts it,

The DNA revolution matters much more than merely replicating results from twin and adoption studies. It is a game-changer for science and society. For the first time, inherited DNA differences across our entire genome of billions of DNA sequences can be used to predict psychological strengths and weaknesses for individuals, called personal genomics.

As an appreciable side benefit, thanks to this revolution we can now officially declare the Blank Slate stone cold dead. It’s noteworthy that this revolutionary advance in our knowledge of the heritable aspects of our behavior did not happen in the field of evolutionary psychology, as one might expect. Diehard Blank Slaters have been directing their ire in that direction for some time. They could have saved themselves the trouble. While the evolutionary psychologists have been amusing themselves inventing inconsequential just so stories about the more abstruse aspects of our sexual behavior, a fifth column that germinated long ago in the field of behavioral genetics was about to drive the decisive nail in their coffin. Obviously, it would have been an inappropriate distraction for Plomin to expand on the fascinating history behind this development in Blueprint.  Read between the lines, though, and its quite clear that he knows what’s been going on.

It turns out that the behavioral geneticists were already astute at dodging the baleful attention of the high priests of the Blank Slate, flying just beneath their radar, at a very early date. A useful source document recounting some of that history entitled, Origins of Behavior Genetics: The Role of The Jackson Laboratory, was published in 2009 by Donald Dewsbury, emeritus professor of psychology at the University of Florida. He notes that,

A new field can be established and coalesce around a book that takes loosely evolving material and organizes it into a single volume. Examples include Watson’s (1914) Behavior: An Introduction to Comparative Psychology and Wilson’s (1975) Sociobiology. It is generally agreed that Fuller and Thompson’s 1960 Behavior Genetics served a similar function in establishing behavior genetics as a separate field.

However, research on the effects of genes on behavior had already begun much earlier. In the 1930’s, when the Blank Slate already had a firm grip on the behavioral sciences, According to the paper, Harvard alumnus Alan Gregg, who was Director of the Medical Sciences Division of Rockefeller Foundation,

…developed a program of “psychobiology” or “mental hygiene” at the Foundation. Gregg viewed mental illness as a fundamental problem in society and believed that there were strong genetic influences. There was a firm belief that the principles to be discovered in nonhuman animals would generalize to humans. Thus, fundamental problems of human behavior might be more conveniently and effectively studied in other species.

The focus on animals turned out to be a very wise decision. For many years it enabled the behavioral geneticists to carry on their work while taking little flak from the high priests of the Blank Slate, whose ire was concentrated on scientists who were less discrete about their interest in humans, in fields such as ethology. Eventually Gregg teamed up with Clarence Little, head of the Jackson Laboratory in Bar Harbor, Maine, and established a program to study mice, rabbits, guinea pigs, and, especially dogs. Gregg wrote papers about selective breeding of dogs for high intelligence and good disposition. However, as his colleagues were aware, another of his goals “was conclusively to demonstrate a high heritability of human intelligence.”

Fast forward to the 60’s. It was a decade in which the Blank Slate hegemony began to slowly crumble under the hammer blows of the likes of Konrad Lorenz, Niko Tinbergen, Robert Trivers, Irenäus Eibl-Eibesfeldt, and especially the outsider and “mere playwright” Robert Ardrey. In 1967 the Institute for Behavioral Genetics (IBG) was established at the University of Colorado by Prof. Jerry McClearn with his colleagues Kurt Schlesinger and Jim Wilson. In the beginning, McClearn et. al. were a bit coy, conducting “harmless” research on the behavior of mice, but by the early 1970’s they had begun to publish papers that were explicitly about human behavior. It finally dawned on the Blank Slaters what they were up to, and they were subjected to the usual “scientific” accusations of fascism, Nazism, and serving as running dogs of the bourgeoisie, but by then it was too late. The Blank Slate had already become a laughing stock among lay people who were able to read and had an ounce of common sense. Only the “experts” in the behavioral sciences would be rash enough to continue futile attempts to breath life back into the corpse.

Would that some competent historian could reconstruct what was going through the minds of McClearn and the rest when they made their bold and potentially career ending decision to defy the Blank Slate and establish the IBG. I believe Jim Wilson is still alive, and no doubt could tell some wonderful stories about this nascent insurgency. In any case, in 1974 Robert Plomin made the very bold decision for a young professor to join the Institute. One of the results of that fortuitous decision was the superb book that is the subject of this post. As noted above, digression into the Blank Slate affair would only have been a distraction from the truly revolutionary developments revealed in his book. However, there is no question that that he was perfectly well aware of what had been going on in the “behavioral sciences” for many years. Consider, for example, the following passage, about why research results in behavioral genetics are so robust and replicate so strongly:

Another reason seems paradoxical: behavioral genetics has been the most controversial topic in psychology during the twentieth century. The controversy and conflict surrounding behavioral genetics raised the bar for the quality and quantity of research needed to convince people of the importance of genetics. This has had the positive effect of motivating bigger and better studies. A single study was not enough. Robust replication across studies tipped the balance of opinion.

As the Germans say, “Was mich nicht umbringt, macht mich stark” (What doesn’t kill me make me strong). If you were looking for a silver lining to the Blank Slate, there you have it. What more can I say. The book is a short 188 pages, but in those pages are concentrated a wealth of knowledge bearing on the critical need of our species to understand itself. If you would know yourself, then by all means, buy the book.
