In the last few posts I have only considered arguments against moral realism, and shown them to be lacking. Yet if you were already convinced of moral anti-realism, this probably didn’t change your mind—it’s entirely possible to have a bad argument for a good idea. (Consider the following argument: “Whales are fish, fish are mammals, therefore whales are mammals.”) What you need is arguments for moral realism.

Fortunately, such arguments are not hard to find. My personal favorite was offered by one of my professors in a philosophy course: “I fail all moral anti-realists. If you think that’s unfair, don’t worry: You’re not a moral anti-realist.” In other words, if you want to talk coherently at all about what actions are good or bad, fair or unfair, then you cannot espouse moral anti-realism; and if you do espouse moral anti-realism, there is no reason for us not to simply ignore you (or imprison you!) and go on living out our moral beliefs—especially if you are right that morality is a fiction. Indeed, the reason we don’t actually imprison all moral anti-realists is precisely because we are moral realists, and we think it is morally wrong to imprison someone for espousing unpopular or even ridiculous beliefs.

That of course is a pragmatic argument, not very compelling on epistemological grounds, but there are other arguments that cut deeper. Perhaps the most compelling is the realization that rationality itself is a moral principle—it says that we ought to believe what conforms to reason and ought not to believe what does not. We need at least some core notion of normativity even to value truth and honesty, to seek knowledge, to even care whether moral realism is correct or incorrect. In a total moral vacuum, we can fight over our values and beliefs, we can kill each other over them, but we cannot discuss them or debate them, for discussion and debate themselves presuppose certain moral principles.

Typically moral anti-realists expect us to accept epistemic normativity, but if they do this then they cannot deny the legitimacy of all normative claims. If their whole argument rests upon undermining normativity, then it is self-defeating. If it doesn’t, then anti-realists need to explain the difference between “moral” and “normative”, and explain why the former is so much more suspect than the latter—but even then we have objective obligations that bind our behavior. The difference, I suppose, would involve a tight restriction on the domains of discourse in which normativity applies. Scientific facts? Normative. Interpersonal relations? Subjective. I suppose it’s logically coherent to say that it is objectively wrong to be a Creationist but not objectively wrong to be a serial killer; but this is nothing if not counter-intuitive.

Moreover, it is unclear to me what a universe would be like if it had no moral facts. In what sort of universe would it not be best to believe what is true? In what sort of universe would it not be wrong to harm others for selfish gains? In what sort of world would it be wrong to keep a promise, or good to commit genocide? It seems to me that we are verging on nonsense, rather like what happens if we try to imagine a universe where 2+2=5.

Moreover, there is a particular moral principle, which depends upon moral realism, yet is almost universally agreed upon, even by people who otherwise profess to be moral relativists or anti-realists.

I call it the Hitler Principle, and it’s quite simple:

The Holocaust was bad.

In large part, ethical philosophy since 1945 has been the attempt to systematically justify the Hitler Principle. Only if moral realism is true can we say that the Holocaust was bad, morally bad, unequivocally, objectively, universally, regardless of the beliefs, feelings, desires, culture or upbringing of its perpetrators. And if we can’t even say that, can we say anything at all? If the Holocaust wasn’t wrong, nothing is. And if nothing is wrong, then does it even matter if we believe what is true?

But then, stop and think for a moment: If we know this—if it’s so obvious to just about everyone that the Holocaust was wrong, so obvious that anyone who denies it we immediately recognize as evil or insane (or lying or playing games)—then doesn’t that already offer us an objective moral standard?

I contend that it does—that the Hitler Principle is so self-evident that it can form an objective standard by which to measure all moral theory. I would sooner believe the Sun revolves around the Earth than deny the Holocaust was wrong. I would sooner consider myself a brain in a vat than suppose that systematic extermination of millions of innocent people could ever be morally justified. Richard Swinburne, a philosopher of religion at Oxford, put it well: “it is more obvious to almost all of us that the genocide conducted by Hitler was morally wrong than that we are not now dreaming, or that the Earth is many millions of years old.” Because at least this one moral fact is so obviously, incorrigibly true, we can use it to test our theories of morality. Just as we would immediately reject any theory of physics which denied that the sky is blue, we should also reject any theory of morality which denies that the Holocaust was wrong. This might seem obvious, but by itself it is sufficient to confirm moral realism.

Similar arguments can be made for other moral propositions that virtually everyone accepts, like the following:

  1. Theft is wrong.
  2. Homicide is wrong.
  3. Lying is wrong.
  4. Rape is wrong.
  5. Kindness is good.
  6. Keeping promises is good.
  7. Happiness is good.
  8. Suffering is bad.

With appropriate caveats (lying isn’t always wrong, if it is justified by some greater good; homicide is permissible in self-defense; promises made under duress do not oblige; et cetera), all of these propositions are accepted by almost everyone, and most people hold them with greater certainty than they would hold any belief about empirical science. “Science proves that time is relative” is surprising and counter-intuitive, but people can accept it; “Science proves that homicide is good” is not something anyone would believe for an instant. There is wider agreement and greater confidence about these basic moral truths than there is about any fact in science, even “the Earth is round” or “gravity pulls things toward each other”—for well before Newton or even Archimedes, people still knew that homicide was wrong.

Though there are surely psychopaths who disagree (basically because their brains are defective), the vast majority of people agree on these fundamental moral claims. At least 95\% of humans who have ever lived share this universal moral framework, under which the wrongness of genocide is as directly apprehensible as the blueness of the sky and the painfulness of a burn. Moral realism is on as solid an epistemic footing as any fact in science.

Expressivism

The theory of expressivism, often posited as an alternative to moral realism, is based on the observation by Hume that factual knowledge is not intrinsically motivating. I can believe that a food is nutritious and that I need nutrition to survive, but without some emotional experience to motivate me—hunger—I will nonetheless remain unmotivated to eat the nutritious food. Because morality is meant to be intrinsically motivating, says Hume, it must not involve statements of fact.

Yet really all Hume has shown is that if indeed facts are not intrinsically motivating, and moral statements are intrinsically motivating, then moral statements are not merely statements of fact. But even statements of fact are rarely merely statements of fact! If I were to walk down the street stating facts at random (lemurs have rings on their tails, the Sun is over one million kilometers in diameter, bicycles have two wheels, people sit on chairs, time dilates as you approach the speed of light, LGBT people suffer the highest per capita rate of hate crimes in the US, Coca-Cola in the United States contains high fructose corn syrup, humans and chimpanzees share 95-98% of our DNA), I would be seen as a very odd sort of person indeed. Even when I state a fact, I do so out of some motivation, frequently an emotional motivation. I’m often trying to explain, or to convince. Sometimes I am angry, and I want to express my anger and frustration. Other times I am sad and seeking consolation. I have many emotions, and I often use words to express them. Nonetheless, in the process I will make many statements of fact that are either true or false: “Humans and chimpanzees share 95-98% of our DNA” I might use to argue in favor of common descent; “Time dilates as you approach the speed of light” I have used in to explain relativity theory; “LGBT people suffer the highest per capita rate of hate crimes in the US” I might use to argue in favor of some sort of gay rights policy. When I say “genocide is wrong!” I probably have some sort of emotional motivation for this—likely my outrage at an ongoing genocide. Nonetheless I’m pretty sure it’s true that genocide is wrong.

Expressivism says that moral statements don’t express propositions at all, they express attitudes, relations to ideas that are not of the same kind as belief and disbelief, truth and falsehood. Much as “Hello!” or “Darn it!” don’t really state facts or inquire about facts, expressivists like Simon Blackburn and Allan Gibbard would say that “Genocide is wrong” doesn’t say anything about the facts of genocide, it merely expresses my attitude of moral disapproval toward genocide.

Yet expressivists can’t abandon all normativity—otherwise even the claim “expressivism is true” has no moral force. Allan Gibbard, like most expressivists, supports epistemic normativity—the principle that we ought to believe what is true. But this seems to me already a moral principle, and one that is not merely an attitude that some people happen to have, but in fact a fundamental axiom that ought to apply to any rational beings in any possible universe. Even more, Gibbard agrees that some moral attitudes are more warranted than others, that “genocide is wrong” is more legitimate than “genocide is good”. But once we agree that there are objective normative truths and moral attitudes can be more or less justified, how is this any different from moral realism?

Indeed, in terms of cognitive science I’m not sure beliefs and emotions are so easily separable in the first place. In some sense I think statements of fact can be intrinsically motivating—or perhaps it is better to put it this way: If your brain is working properly, certain beliefs and emotions will necessarily coincide. If you believe that you are about to be attacked by a tiger, and you don’t experience the emotion of fear, something is wrong; if you believe that you are about to die of starvation, and you don’t experience the emotion of hunger, something is wrong. Conversely, if you believe that you are safe from all danger, and yet you experience fear, something is wrong; if you believe that you have eaten plenty of food, yet you still experience hunger, something is wrong. When your beliefs and emotions don’t align, either your beliefs or your emotions are defective. I would say that the same is true of moral beliefs. If you believe that genocide is wrong but you are not motivated to resist genocide, something is wrong; if you believe that feeding your children is obligatory but you are not motivated to feed your children, something is wrong.

It may well be that without emotion, facts would never motivate us; but emotions can warranted by facts. That is how we distinguish depression from sadness, mania from joy, phobia from fear. Indeed I am dubious of the entire philosophical project of noncognitivism, of which expressivism is the moral form. Noncognitivism is the idea that a given domain of mental processing is not cognitive—not based on thinking, reason, or belief. There is often a sense that noncognitive mental processing is “lower” than cognition, usually based on the idea that it is more phylogenetically conserved—that we think as men but feel as rats.

Yet in fact this is not how human emotions work at all. Poetry—mere words—often evokes the strongest of emotions. A text message of “I love you” or “I think we should see other people” can change the course of our lives. An ambulance in the driveway will pale the face of any parent. In 2001 the video footage of airplanes colliding with skyscrapers gave all of America nightmares for weeks. Yet stop and think about what text messages, ambulances, video footage, airplanes, and skyscrapers are—they are technologies so advanced, so irreducibly cognitive, that even the world’s technological superpower had none of them 200 years ago. (We didn’t have text messages forty years ago!) Even something as apparently dry as numbers can have profound emotional effects: In the statements “Your blood sugar is X mg/dL” to a diabetic, “You have Y years to live” to a cancer patient, or “Z people died” in a news report, the emotional effects are almost wholly dependent upon the value of the numbers X, Y, and Z—values of X = 100, Y = 50 and Z = 0 would be no cause for alarm (or perhaps even cause for celebration!), while values of X = 400, Y = 2, and Z = 10,000 would trigger immediate shock, terror and despair. The entire discipline of cognitive-behavioral psychotherapy depends upon the fact that talking to people about their thoughts and beliefs can have profound effects upon their emotions and actions—and in empirical studies, cognitive-behavioral psychotherapy is verified to work in a variety of circumstances and is more effective than medication for virtually every mental disorder. We do not think as men but feel as rats; we thinkandfeel as human beings.

Because they are evolved instincts, we have limited control over them, and other animals have them, we are often inclined to suppose that emotions are simple, stupid, irrational—but on the contrary they are mind-bogglingly complex, brilliantly intelligent, and the essence of what it means to be a rational being. People who don’t have emotions aren’t rational—they are inert. In psychopathology a loss of capacity for emotion is known as flat affect, and it is often debilitating; it is often found in schizophrenia and autism, and in its most extreme forms it causes catatonia—that is, a total lack of body motion. From Plato to Star Trek, Western culture has taught us to think that a loss of emotion would improve our rationality; but on the contrary, a loss of all emotion would render us completely vegetative. Lieutenant Commander Data without his emotion chip should stand in one place and do nothing—for this is what people without emotion actually do.

Indeed, attractive and aversive experiences—that is, emotions—are the core of goal-seeking behavior, without which rationality is impossible. Apparently simple experiences like pleasure and pain (let alone obviously complicated ones like jealousy and patriotism) are so complex that the most advanced robots in the world cannot even get close to simulating them. Injure a rat, and it will withdraw and cry out in pain; damage a robot (at least any less than a state-of-the-art research robot), and it will not react at all, continuing ineffectually through the same motions it was attempting a moment ago. This shows that rats are smarter than robots—an organism that continues on its way regardless of the stimulus is more like a plant than an animal.

Our emotions do sometimes fail us. They hurt us, they put us at risk, they make us behave in ways that are harmful or irrational. Yet to declare on these grounds that emotions are the enemy of reason would be like declaring that we should all poke out our eyes because sometimes we are fooled by optical illusions. It would be like saying that a shirt with one loose thread is unwearable, that a mathematician who once omits a negative sign should never again be trusted. This is not rationality but perfectionism. Like human eyes, human emotions are rational the vast majority of the time, and when they aren’t, this is cause for concern. Truly irrational emotions include mania, depression, phobia, and paranoia—and it’s no accident that we respond to these emotions with psychotherapy and medication.

Expressivism is legitimate precisely because it is not a challenger to moral realism. Personally, I think that expressivism is wrong because moral claims express facts as much as they express attitudes; but given our present state of knowledge about cognitive science, that is the sort of question upon which reasonable people can disagree. Moreover, the close ties between emotion and reason may ultimately entail that we are wrong to make the distinction in the first place. It is entirely reasonable, at our present state of knowledge, to think that moral judgments are primarily emotional rather than propositional. What isnot reasonable, however, is the claim that moral statements cannot be objectively justified—the evidence against this claim is simply too compelling to ignore. If moral claims are emotions, they are emotions that can be objectively justified.

Against Moral Relativism

Moral relativism is surprisingly common, especially among undergraduate students. There are also some university professors who espouse it, typically but not always from sociology, gender studies or anthropology departments (examples include Marshall Sahlins, Stanley Fish, Susan Harding, Richard Rorty, Michael Fischer, and Alison Renteln). There is a fairly long tradition of moral relativism, from Edvard Westermarck in the 1930s to Melville Herskovits, to more recently Francis Snare and David Wong in the 1980s. University of California Press at Berkeley.} In 1947, the American Anthropological Association released a formal statement declaring that moral relativism was the official position of the anthropology community, though this has since been retracted.

All of this is very, very bad, because moral relativism is an incredibly naive moral philosophy and a dangerous one at that. Vitally important efforts to advance universal human rights are conceptually and sometimes even practically undermined by moral relativists. Indeed, look at that date again: 1947, two years after the end of World War II. The world’s civilized cultures had just finished the bloodiest conflict in history, including some ten million people murdered in cold blood for their religion and ethnicity, and the very survival of the human species hung in the balance with the advent of nuclear weapons—and the American Anthropological Association was insisting that morality is meaningless independent of cultural standards? Were they trying to offer an apologia for genocide?

What is relativism trying to say, anyway? Often the arguments get tied up in knots. Consider a particular example, infanticide. Moral relativists will sometimes argue, for example, that infanticide is wrong in the modern United States but permissible in ancient Inuit society. But is this itself an objectively true normative claim? If it is, then we are moral realists. Indeed, the dire circumstances of ancient Inuit society would surely justify certain life-and-death decisions we wouldn’t otherwise accept. (Compare “If we don’t strangle this baby, we may all starve to death” and “If we don’t strangle this baby, we will have to pay for diapers and baby food”.) Circumstances can change what is moral, and this includes the circumstances of our cultural and ecological surroundings. So there could well be an objective normative fact that infanticide is justified by the circumstances of ancient Inuit life. But if there are objective normative facts, this is moral realism. And if there are no objective normative facts, then all moral claims are basically meaningless. Someone could just as well claim that infanticide is good for modern Americans and bad for ancient Inuits, or that larceny is good for liberal-arts students but bad for engineering students.

If instead all we mean is that particular acts are perceived as wrong in some societies but not in others, this is a factual claim, and on certain issues the evidence bears it out. But without some additional normative claim about whose beliefs are right, it is morally meaningless. Indeed, the idea that whatever society believes is right is a particularly foolish form of moral realism, as it would justify any behavior—torture, genocide, slavery, rape—so long as society happens to practice it, and it would never justify any kind of change in any society, because the status quo is by definition right. Indeed, it’s not even clear that this is logically coherent, because different cultures disagree, and within each culture, individuals disagree. To say that an action is “right for some, wrong for others” doesn’t solve the problem—because either it is objectively normatively right or it isn’t. If it is, then it’s right, and it can’t be wrong; and if it isn’t—if nothing is objectively normatively right—then relativism itself collapses as no more sound than any other belief.

In fact, the most difficult part of defending common-sense moral realism is explaining why it isn’t universally accepted. Why are there so many relativists? Why do so many anthropologists and even some philosophers scoff at the most fundamental beliefs that virtually everyone in the world has?

I should point out that it is indeed relativists, and not realists, who scoff at the most fundamental beliefs of other people. Relativists are fond of taking a stance of indignant superiority in which moral realism is just another form of “ethnocentrism” or “imperialism”. The most common battleground of contention recently is the issue of female circumcision, which is considered completely normal or even good in some African societies but is viewed with disgust and horror by most Western people. Other common choices include abortion, clothing, especially Islamic burqa and hijab, male circumcision, and marriage; given the incredible diversity in human food, clothing, language, religion, behavior, and technology, there are surprisingly few moral issues on which different cultures disagree—but relativists like to milk them for all they’re worth!

But I dare you, anthropologists: Take a poll. Ask people which is more important to them, their belief that, say, female circumcision is immoral, or their belief that moral right and wrong are objective truths? Virtually anyone in any culture anywhere in the world would sooner admit they are wrong about some particular moral issue than they would assent to the claim that there is no such thing as a wrong moral belief. I for one would be more willing to abandon just about any belief I hold before I would abandon the belief that there are objective normative truths. I would sooner agree that the Earth is flat and 6,000 years old, that the sky is green, that I am a brain in a vat, that homosexuality is a crime, that women are inferior to men, or that the Holocaust was a good thing—than I would ever agree that there is no such thing as right or wrong. This is of course because once I agreed that there is no objective normative truth, I would be forced to abandon everything else as well—since without objective normativity there is no epistemic normativity, and hence no justice, no truth, no knowledge, no science. If there is nothing objective to say about how we ought to think and act, then we might as well say the Earth is flat and the sky is green.

So yes, when I encounter other cultures with other values and ideas, I am forced to deal with the fact that they and I disagree about many things, important things that people really should agree upon. We disagree about God, about the afterlife, about the nature of the soul; we disagree about many specific ethical norms, like those regarding racial equality, feminism, sexuality and vegetarianism. We may disagree about economics, politics, social justice, even family values. But as long as we are all humans, we probably agree about a lot of other important things, like “murder is wrong”, “stealing is bad”, and “the sky is blue”. And one thing we definitely do not disagree about—the one cornerstone upon which all future communication can rest—is that these things matter, that they really do describe actual features of an actual world that are worth knowing. If it turns out that I am wrong about these things, \I would want to know! I’d much rather find out I’d been living the wrong way than continue to live the same pretending that it doesn’t matter. I don’t think I am alone in this; indeed, I suspect that the reason people get so angry when I tell them that religion is untrue is precisely because they realize how important it is. One thing religious people never say is “Well, God is imaginary to you, perhaps; but to me God is real. Truth is relative.” I’ve heard atheists defend other people’s beliefs in such terms—but no one ever defends their own beliefs that way. No Evangelical Baptist thinks that Christianity is an arbitrary social construction. No Muslim thinks that Islam is just one equally-valid perspective among many. It is you, relativists, who deny people’s fundamental beliefs.

Yet the fact that relativists accuse realists of being chauvinistic hints at the deeper motivations of moral relativism. In a word: Guilt. Moral relativism is an outgrowth of the baggage of moral guilt and self-loathing that Western societies have built up over the centuries. Don’t get me wrong: Western cultures have done terrible things, many terrible things, all too recently. We needn’t go so far back as the Crusades or the ethnocidal “colonization” of the Americas; we need only look to the carpet-bombing of Dresden in 1945 or the defoliation of Vietnam in the 1960s, or even the torture program as recently as 2009. There is much evil that even the greatest nations of the world have to answer for. For all our high ideals, even America, the nation of “life, liberty, and the pursuit of happiness”, the culture of “liberty and justice for all”, has murdered thousands of innocent people—and by “murder” I mean murder, killing not merely by accident in the collateral damage of necessary war, but indeed in acts of intentional and selfish cruelty. Not all war is evil—but many wars are, and America has fought in some of them. No Communist radical could ever burn so much of the flag as the Pentagon itself has burned in acts of brutality.

Yet it is an absurd overreaction to suggest that there is nothing good about Western culture, nothing valuable about secularism, liberal democracy, market economics, or technological development. It is even more absurd to carry the suggestion further, to the idea that civilization was a mistake and we should all go back to our “natural” state as hunter-gatherers. Yet there are anthropologists working today who actually say such things. And then, as if we had not already traversed so far beyond the shores of rationality that we can no longer see the light of home, then relativists take it one step further and assert that any culture is as good as any other.

Think about what this would mean, if it were true. To say that all cultures are equal is to say that science, education, wealth, technology, medicine—all of these are worthless. It is to say that democracy is no better than tyranny, security is no better than civil war, secularism is no better than theocracy. It is to say that racism is as good as equality, sexism is as good as feminism, feudalism is as good as capitalism.

Many relativists seem worried that moral realism can be used by the powerful and privileged to oppress others—the cishet White males who rule the world (and let’s face it, cishet White males do, pretty much, rule the world!) can use the persuasive force of claiming objective moral truth in order to oppress women and minorities. Yet what is wrong with oppressing women and minorities, if there is no such thing as objective moral truth? Only under moral realism is oppression truly wrong.
