Can a computer be conscious?

What It Will Take for Computers to Be Conscious

The world’s best-known consciousness researcher says machines could one day become self-aware.

Is a worm conscious? How about a bumblebee? Does a computer that can play chess “feel” anything?
Christof Koch
Christof Koch
To Christof Koch, chief scientific officer of the Allen Institute for Brain Science in Seattle, the answer to these questions may lie in the fabric of the universe itself. Consciousness, he believes, is an intrinsic property of matter, just like mass or energy. Organize matter in just the right way, as in the mammalian brain, and voilĂ , you can feel.
Koch, now 57, has spent nearly a quarter of a century trying to explain why, say, the sun feels warm on your face. But after writing three books on consciousness, Koch says researchers are still far from knowing why it occurs, or even agreeing on what it is. It’s a difficult problem (see “Cracking the Brain’s Codes”). That is one reason that Koch left his position at Caltech in 2011 to become part of a $500 million project launched by the billionaire Paul Allen, Microsoft’s cofounder.
The Allen Institute’s goal is to build a detailed atlas of every neuron and synapse in the mammalian brain. That would give neuroscience a firehose of data similar to what the Human Genome Project achieved.
But Koch hasn’t given up his search for a grand theory that could explain it all. In fact, he thinks consciousness could be explained by something called “integrated information theory,” which asserts that consciousness is a product of structures, like the brain, that can both store a large amount of information and have a critical density of interconnections between their parts.
To Koch, the theory provides a means to assess degrees of consciousness in people with brain damage, in species across the animal kingdom, and even, he says, among machines. We asked Koch about computer consciousness last week during MIT Technology Review’s EmTech conference.
Will discovering the biological basis of consciousness be dehumanizing in some way? What if it’s all just an illusion? 
I find this view of some people that consciousness is an illusion to be ridiculous. If it’s an illusion, then it’s the most powerful illusion we have. I mean, the most famous deduction in Western philosophy is what? “I think. Therefore I am.” The fact that you have conscious experience is the one undeniable certainty you have.
If scientists discover the basis of consciousness, what kinds of technologies could result from that? 
We could have a test to say who has consciousness and who doesn’t. We have very emotional debates in this country about abortion. I would like to have some objective way to test at what point a fetus actually begins to have conscious sensation. Or whether a patient [in a coma] is conscious or not. Often, you just don’t know. These are questions that people have asked since historic times, but once we have a theory, and a widely accepted theory, we could answer them. Also, if I wanted to build a machine that would be conscious, it would give me a blueprint.
So you think a computer can be conscious? 
I gave a lecture [last week] at MIT about Integrated Information Theory, developed by Giulio Tononi at the University of Wisconsin. This is a theory that makes a very clear prediction: it says that consciousness is a property of complex systems that have a particular “cause-effect” repertoire. They have a particular way of interacting with the world, such as the brain does, or in principle, such as a computer could. If you were to build a computer that has the same circuitry as the brain, this computer would also have consciousness associated with it. It would feel like something to be this computer. However, the same is not true for digital simulations.
If I build a perfect software model of the brain, it would never be conscious, but a specially designed machine that mimics the brain could be?
Correct. This theory clearly says that a digital simulation would not be conscious, which is strikingly different from the dominant functionalist belief of 99 percent of people at MIT or philosophers like Daniel Dennett. They all say, once you simulate everything, nothing else is required, and it’s going to be conscious.
I think consciousness, like mass, is a fundamental property of the universe. The analogy, and it’s a very good one, is that you can make pretty good weather predictions these days. You can predict the inside of a storm. But it’s never wet inside the computer. You can simulate a black hole in a computer, but space-time will not be bent. Simulating something is not the real thing.
It’s the same thing with consciousness. In 100 years, you might be able to simulate consciousness on a computer. But it won’t experience anything. Nada. It will be black inside. It will have no experience whatsoever, even though it may have our intelligence and our ability to speak.
I am not saying consciousness is a magic soul. It is something physical. Consciousness is always supervening onto the physical. But it takes a particular type of hardware to instantiate it. A computer made up of transistors, moving charge on and off a gate, with each gate being connected to a small number of other gates, is just a very different cause-and-effect structure than what we have in the brain, where you have one neuron connected to 10,000 input neurons and projecting to 10,000 other neurons. But if you were to build the computer in the appropriate way, like a neuromorphic computer [see “Thinking in Silicon”], it could be conscious.
If I were to put you in a room with a computer from the future, would you be able to determine if it’s conscious? 
I couldn’t from the outside. I would have to look at its hardware.
What about the Turing test?
The question Turing asked is “Can machines think?” But ultimately it’s an operational test for intelligence, not for consciousness. If you have a clever conversation with some guy in another room and after half an hour you can’t decide if it is a computer or a human, well, then you say it’s as intelligent as a human. But the Turing test would not tell me if the machine experiences anything. I could ask “Are you conscious?” and the machine could say “Yes, I am fully conscious. And why are you claiming I am not? I am insulted.” But I couldn’t really know. I’d have to say, “Sorry, I have to take you apart and understand how you are made and how you actually generate these different physical states.”
Isn’t there some trick question you could ask, that only a conscious being could answer? 
A very good question. In humans we have practical tests for consciousness. If you have a bad accident and go to the ER, they will ask you: Can you move your eyes? Can you move your limbs? Can you talk? If you can talk, do you know what year it is? Do you know who the president is?
But how do I really know you are conscious? This is the problem of solipsism. In the last analysis I do not know. But I know your brain is very similar to mine. I have put a lot of people into scanners, and I know they all have a brain, and their brains behave similar to mine. So there is a perfectly reasonable inference that you too are conscious.
But the more these systems differ from me, the more difficult it is to make that step by inference. For instance, take a bee. Does it feel like something to be a bee and fly in the golden sun rays and have nectar? I find it very difficult to know if a bee is conscious or not conscious. And a computer is even more radically different. There is no behavior I can judge it by. I would have to look at its underlying hardware.
Do you think we will ever build conscious machines?
I’m not sure why we would. But there is no question in my mind that we will build smart machines that can pass the Turing test well before we understand the true biological basis of human intelligence. And I think there are dangers associated with that which most people, being blithe optimists, completely ignore.
What dangers?
Don’t you watch science fiction movies? “Runaway AI” of course. Think about the financial market, all those trading machines, flash crashes. People are going to abuse computer intelligence, blindly maximize for some goal. It’s going to lead to more and more concentration of power among fewer and fewer people. We see this already, it’s going to lead to massive unemployment. And maybe 30 or 40 years on I think there is really an existentialist danger to the species, at the level of nuclear weapons or a meteorite strike.
All without the machine being conscious? In the movies, the moment the AI goes nuts is the same moment that it gains conscious self-awareness.
That’s because people want to make an engaging story. If the enemy doesn’t feel anything, if there isn’t anything there, it doesn’t make a good opponent.

Does Religion make us moral

This is chapter 10 of Daniel C Dennett's book "Breaking the Spell". Here he debunks the idea that religion makes us moral.



1. Does religion make us moral?

Then Jesus beholding him loved him, and said unto him, One thing thou lackest: go thy way, sell whatsoever thou hast, and give to the poor, and thou shalt have treasure in heaven: and come, take up the cross, and follow me. — Mark 10:21

The Lord trieth the righteous: but the wicked and him that loveth violence his soul hateth. Upon the wicked he shall rain snares, fire and brimstone, and an horrible tempest, this shall be the portion of their cup. — Psalms 11:5-6

Believing as I do that man in the distant future will be a far more perfect creature than he now is, it is an intolerable thought that he and all other sentient beings are doomed to complete annihilation after such long-continued slow progress. To those who fully admit the immortality of the human soul, the destruction of our world will not appear so dreadful. — Charles Darwin, Life and Letters

Non-Muslims love their life too much, they can't fight, and they are cowards. They don't understand that there will be life after death. You cannot live forever, you will die. Life after death is forever. If life after death were an ocean, the life you live is only a drop in the ocean. So it's very important that you live your life for Allah, so you are rewarded after death. — A young mujaheed from Pakistan, quoted by Jessica Stern, Terror in the Name of God

Good people will do good things, and bad people will do bad things. But for good people to do bad things — that takes religion. — Steven Weinberg, 1999

Religion plays its most important role in supporting morality, many think, by giving people an unbeatable reason to do good: the promise of an infinite reward in heaven, and (depending on tastes) the threat of an infinite punishment in hell if they don't. Without the divine carrot and stick, goes this reasoning, people would loll about aimlessly or indulge their basest desires, break their promises, cheat on their spouses, neglect their duties, and so on. There are two well-known problems with this reasoning: (1) it doesn't seem to be true, which is good news, since (2) it is such a demeaning view of human nature.

I have uncovered no evidence to support the claim that people, religious or not, who don't believe in reward in heaven and/or punishment in hell are more likely to kill, rape, rob, or break their promises than people who do.  The prison population in the United States shows Catholics, Protestants, Jews, Muslims, and others — including those with no religious affiliation — represented about as they are in the general population. Brights and others with no religious affiliation exhibit the same range of moral excellence and turpitude as born-again Christians, but, more to the point, so do members of religions that de-emphasize or actively deny any relationship between moral behavior "on earth" and eventual postmortem reward and punishment. And when it comes to "family values," the available evidence to date supports the hypothesis that brights have the lowest divorce rate in the United States, and born-again Christians the highest (Barna, 1999). Needless to say, these results strike so hard at the standard claims of greater moral virtue among the religious that there has been a considerable surge of further research initiated by religious organizations attempting to refute them. At this time, nothing very surprising has emerged, and nothing approaching a settled consensus among researchers has been achieved, but one thing we can be sure of is that if there is a significant positive relationship between moral behavior and religious affiliation, practice, or belief, it will soon be discovered, since so many religious organizations are eager to confirm their traditional beliefs about this scientifically. (They are quite impressed with the truth-finding power of science when it supports what they already believe.) Every month that passes without such a demonstration underlines the suspicion that it just isn't so.

It is clear enough why believers might want to come up with evidence that belief in heaven and hell has benign effects. Everybody already knows the evidence for the countervailing hypothesis that the belief in a reward in heaven can sometimes motivate acts of monstrous evil. Nevertheless, there are many in the religious community who would not welcome the demonstration that a belief in God's reward in heaven or punishment in hell makes a significant difference, since they view this as an infantile concept of God in the first place, pandering to immaturity instead of encouraging genuine moral commitment. As Mitchell Silver notes, the God who rewards goodness in heaven bears a striking resemblance to the hero of the popular song "Santa Claus Is Coming to Town."

Like Santa, God "knows if you are sleeping, he knows if you're awake, he knows if you've been bad or good" . . . The lyrics continue "so be good for goodness' sake." Catchy but a logical solecism. In logic the song should have continued "so be good for the sake of the electronic equipment, dolls, sports gear and other gifts you hope to get but will get only if the omniscient and just Santa judges you worthy of receiving."If you were good for goodness' sake, the all-seeing Santa would be irrelevant as a motivator of your virtue. [In press]

Moral philosophers who have agreed about little else, from the days of Hume and Kant through Nietzsche to the present, have regarded this pie-in-the-sky vision of morality as something of a trap, a reductio ad absurdum into which only the most unwary moralist would fall. Many religious thinkers agree: a doctrine that trades in a person's good intentions for the prudent desires of a rational maximizer shopping around for eternal bliss may win a few cheap victories, luring a few selfish and unimaginative souls into behaving themselves for a while, but at the cost of debasing their larger campaign for goodness. We see an echo of this familiar recognition in the derision heaped by many commentators on the Al Qaeda hijackers of 9/11 for their purported goal of luxuriating in heaven with seventy-two virgins (each) as the reward for their martyrdom.

We may shun this theme as a foundation of our morality today yet still honor it for having played a founding role in the past, as a ladder that, once climbed, may be discarded. How could this work? The economist Thomas Schelling has pointed out that "belief in a deity who will reward goodness and punish evil transforms many situations from subjective to secured, at least in the believer's mind" (quoted in Nesse, ed., 2001, p. 16). Consider a situation in which two parties confront each other with a prospect for cooperating on something both parties would want, but each is afraid the other will renege on any bargain struck, and there are no authorities or stronger parties around to enforce it. Promises can be made and then broken, but sometimes they can be secured. A commitment may be secured by being self-enforcing; for instance, you can burn your bridges behind you so you can't escape even if you change your mind. Or it may be secured by your greater desire to preserve your reputation. You may have good reason to fulfill your side of a contract even if your reason for signing it in the first place has lapsed, simply because your reputation is also at stake, a valuable social commodity indeed. Or — and this is Schelling's point — a promise made "in the eyes of God" may well convince those who believe in that God that a sort of virtual escrow account has been created, protecting both parties and giving each the confidence to move ahead without fear of reneging by the other party.

Consider the current situation in Iraq, where a security force is supposed to provide a temporary scaffolding on which to construct a working society in post-Saddam Iraq. It might actually have worked from the outset if the force had been large enough and well enough trained and deployed to reassure people without having to fire a shot. With insufficient forces, the credibility of the peacekeepers was diminished, however, and a positive feedback cycle of violence was put in motion, destroying confidence in security. How can you break out of such a downward spiral? It is hard to say. The flawed and fragile democracy that has been installed may still overcome its corrupt and violence-ridden beginnings, if the world is lucky, however forlorn it looks today. Failed states have a way of perpetuating themselves, and perpetuating both the misery of their inhabitants and the insecurity of their neighbors. In the distant past, the very idea of an overseeing God might often have permitted an otherwise chaotic and ungovernable population to bootstrap itself into a working state, with enough law and order so that credible promising could take hold. Only in such a climate of trust can investment and commerce and free passage, and all the other things we take for granted in a working society, flourish. Such a meme would be vulnerable to collapse if its credibility was threatened, just as surely as the occupying forces in Iraq depend on their (problematic) credibility for their own effectiveness. The rationale for incorporating whatever doubt-suppression devices could be found would have been obvious (to the blind forces of cultural selection, and probably to the authorities themselves).

Today, when patterns of mutual trust are quite securely established in modern democratic states independently of any shared religious belief, the bristling defenses of religions against corrosive doubt begin to look vestigial, like fossil traces of an earlier epoch. We no longer need God the Policeman to create a climate in which we can make promises and conduct human affairs on their basis, but He lives on in legal oaths — and in the imaginations of many who are terrified of the prospect of abandoning religion.

But reward in heaven is not the only — and certainly not the best — inspirational theme in religious doctrine. The God who is watching you need not be seen to be either list-making Santa or Orwell's Big Brother, but instead a hero or "role model," as we say today, someone to emulate rather than fear. If God is just, and merciful, and forgiving, and loving, and the most wonderful Being imaginable, then anyone who loves God should want to be just, and merciful, and forgiving, and loving, for goodness' sake. Blurring these two very different views of God's motivating role into one is yet another casualty of the gauze curtains of soft-focus veneration through which we traditionally inspect religion.

Still, there may be the best of (free-floating) reasons for not peering too closely at these fine differences between doctrines. Why create dissension where none need exist? Don't rock the boat. It is widely agreed that all religions provide social infrastructures for creating and maintaining moral teamwork. Perhaps their value as organizers and amplifiers of good intentions far outweighs any deficits created by the putative incoherence created by contradictions between (some of) their doctrines. Perhaps it would be foolish perfectionism, and an act of moral ineptitude, to distract ourselves with minor conflicts of dogma when there is so much work to be done making the world a better place.

This is a persuasive claim, but it has the disadvantage of undercutting itself somewhat in public, since it amounts to making the acknowledgment that "good as we are, we aren't perfect, but we have more important things to do than fix our foundations" — a modest admission that jars with the traditional claims of purity that religions find irresistible. Moreover, any such lapses from absolutism threaten to undermine the chief psychological source of the very organizational power that is being recognized. Today's religious warriors may be too sophisticated to expect their God to stop the bullets in midair at their behest, but their belief in the absolute rightness of their cause may well be a crucial ingredient in creating the calm with which truly effective soldiers go into battle. As William James puts it:
Whoever not only says, but feels, "God's will be done," is mailed [armored] against every weakness; and the whole historic array of martyrs, missionaries, and religious reformers is there to prove the tranquil-mindedness, under naturally agitating or distressing circumstances, which self-surrender brings. [1902, p. 285]

This heroic state of mind does not harmonize well with secular modesty, and though many think it is true that religious fanatics make the most reliable soldiers, we may well wonder whether, all things considered, James is right when he goes on to note (quoting "a clear-headed Austrian officer"), "Far better is it for an army to be too savage, too cruel, too barbarous, than to possess too much sentimentality and human reasonableness" (p. 366). Here is a morally relevant question well worth careful empirical investigation: can a secular armed force, motivated in the main by a love of liberty or democracy, not of God (or Allah), maintain its credibility, and hence its effectiveness, with a minimum of bloodshed, against an army of fanatics? Until we know the answer, we risk being blackmailed by sheer fear into indoctrinating the troops with barbarism. It will take a combination of courage and wise planning — and maybe a large helping of luck — even to do the research needed to find out. But the alternative is even more grim: perpetuating the fatal downward spiral of "righteous" wars, fought by misguided young people sent into dubious battle by leaders who don't really believe the myths that sustain those who are risking their lives. As the Grand Inquisitor says in Dostoevski's The Brothers Karamazov, "Beyond the grave they will find nothing but death. But we shall keep the secret, and for their happiness we shall allure them with the reward of heaven and eternity."

There is a further allure for the zealot, and it is probably — who knows? — a more robust motivator than the prospect of heavenly reward: the license to kill (to adapt Ian Fleming's all-too-appealing fantasy about the official status of James Bond). Some people, it seems — who knows? — are just bloodthirsty, or thrill-seeking, and as our customs become ever more civilized and opposed to violence, such people are highly motivated to find a cause that can provide them with a "moral" justification for their swashbuckling, whether it is "liberating" laboratory animals (whose subsequent welfare seems not to motivate the activists sufficiently), avenging Ruby Ridge with the Oklahoma City bombing, murdering doctors who perform abortions, sending anthrax to "evil" federal employees, murdering an innocent person under cover of fatwa, achieving martyrdom in jihad, or becoming a "settler" (armed to the teeth) in the West Bank territory. Religion may well not be the root cause of this dangerous yearning; the Hollywood-inspired desire to lead an adventurous and hence "meaningful" life may play a larger role in multiplying the number of young people who decide to frame their lives in such terms. But religions are certainly the most prolific source of the "moral certainties" and "absolutes" that such zealotry depends on. And although people who can see the shades of gray are less apt to be able to find excuses for committing criminal acts themselves, they are also, today, all too likely to see devout religious conviction as a significantly mitigating factor when meting out punishment. (We can hope that this will change swiftly if given sufficient public attention. We used to regard drunks as somewhat diminished in their responsibility for their actions — they were too drunk to know what they were doing, after all — but we now see them, and the bartenders who served them, as fully responsible. We need to spread the word that religious intoxication is no excuse either.)

2. Is religion what gives meaning to your life?

A puppet of the gods is a tragic figure, a puppet suspended on his chromosomes is merely grotesque. — Arthur Koestler, The Sleepwalkers

Ohhh, McTavish is dead and his brother don't know it; His brother is dead and McTavish don't know it. They're both of them dead and they're in the same bed, And neither one knows that the other is dead! 
— Lyrics to the "Irish Washerwoman" jig

According to surveys, most of the people in the world say that religion is very important in their lives. (See, e.g., the Web site of the Pew Research Center, http://people-press.org/.) Many of these people would say that without their religion their lives would be meaningless. It's tempting just to take them at their word, to declare that in that case there is really nothing more to be said — and tiptoe away. Who would want to interfere with whatever it is that gives their lives meaning? But if we do that, we willfully ignore some serious questions. Can just any religion give lives their meaning, in a way that we should honor and respect? What about people who fall into the clutches of cult leaders, or who are duped into giving their life savings to religious con artists? Do their lives still have meaning even though their particular "religion" is a fraud?

In Marjoe, the 1972 documentary about the bogus evangelist Marjoe Gortner mentioned in chapter 6, we see poor people emptying their wallets and purses into the collection plate, their eyes glistening with tears of joy, thrilled to be getting "salvation" from this charismatic phony. The question that has been troubling me ever since I saw the film when it first came out is: who is committing the more reprehensible act — Marjoe Gortner, who lies to these people in order to get their money, or the filmmakers who expose these lies (with Gortner's enthusiastic complicity), thereby robbing these good folk of the meaning they thought they had found for their lives? Were they not getting their money's worth and then some before the filmmakers came along? Consider their lives (I am imagining these details, which are not in the documentary): Sam is a high-school dropout, pumping gas at the station at the crossroads and hoping someday to buy a motorcycle; he is a Dallas Cowboys fan, and likes to have a few beers while watching the games on TV. Lucille, who never married, is in charge of the night-shift shelfstockers at the local supermarket and lives in the modest house she has always lived in, caring for her aged mother; they follow the soap operas together. No adventurous opportunities beckon in the futures of Sam or Lucille, or most of the others in the blissful congregation, but they have now been put in direct contact with Jesus and are now saved for eternity, beloved members in good standing of the community of the born-again. They have turned over a new leaf, in a most dramatic ceremony, and they face their otherwise uninspiring lives refreshed and uplifted. Their lives now tell a story, and it's a chapter of the Greatest Story Ever Told. Can you imagine anything else they could buy with those twenty-dollar bills they deposit in the collection plate that would be remotely as valuable to them?

Certainly, comes the reply. They could donate their money to a religion that was honest, and that actually used their sacrifices to help others who were still needier. Or they could join any secular organization that put their free time, energy, and money to effective use in ameliorating some of the world's ills. Perhaps the main reason that religions do most of the heavy lifting in large parts of America is that people really do want to help others — and secular organizations have failed to compete with religions for the allegiance of ordinary people. That's important, but it's the easy part of the answer, leaving untouched the hard part: what should we do about those we honestly think are being conned? Should we leave them to their comforting illusions or blow the whistle? I have eventually come to the tentative conclusion that Marjoe Gortner and his filmmaking collaborators performed a great public service in spite of the pain and humiliation the film no doubt caused to many basically innocent people, but further details, or just further reflection on the details that are known, might lead me to change my mind.

Dilemmas like this are all too familiar in somewhat different contexts, of course. Should the sweet old lady in the nursing home be told that her son has just been sent to prison? Should the awkward twelve-year-old boy who wasn't cut from the baseball team be told about the arm-twisting by all the parents that persuaded the coach to keep him on the squad? In spite of ferocious differences of opinion about other moral issues, there seems to be something approaching consensus that it is cruel and malicious to interfere with the life-enhancing illusions of others — unless those illusions are themselves the cause of even greater ills. The disagreements come over what these greater ills might be — and this has led to the breakdown of the whole rationale. Keeping secrets from people for their own good can often be wise, but it takes only one person to give away a secret, and since there are disagreements about which cases warrant discretion, the result is an unsavoury miasma of hypocrisy, lies, and frantic but fruitless attempts at distraction.

What if Marjoe Gortner were to con a cadre of sincere evangelical preachers into doing his dirty work for him? Would their personal innocence change the equation and give genuine meaning to the lives of those whose sacrifices they encouraged and collected? For that matter, aren't all evangelical preachers just as false as Marjoe Gortner? Certainly Muslims think so, even though they are generally too discreet to say it. And Catholics think that Jews are just as deluded, and Protestants think that Catholics are wasting their time and energy on a largely false religion, and so forth. All Muslims? All Catholics? All Protestants? AllJews? Of course not. There are vocal minorities in every faith who blurt it out, like the Catholic movie star Mel Gibson, who was interviewed by Peter Boyer (2003) in a profile in The New Yorker. Boyer asked him if Protestants are denied eternal salvation.

"There is no salvation for those outside the Church," Gibson replied. "I believe it." He explained: "Put it this way. My wife is a saint. She's a much better person than I am. Honestly. She's, like, Episcopalian, Church of England. She prays, she believes in God, she knows Jesus, she believes in that stuff. And it's just not fair if she doesn't make it, she's better than I am. But that is a pronouncement from the chair. I go with it."

Such remarks deeply embarrass two groups of Catholics: those who believe it but think it is best left unsaid, and those who don't believe it at all — no matter what "the chair" may pronounce. And which group of Catholics is larger, or more influential? That is utterly unknown and currently unknowable, a part of the unsavoury miasma.

It is equally unknown how many Muslims truly believe that all infidels and especially kafirs (apostates from Islam) deserve death, which is what the Koran (5:44) undeniably says. Johannes Jansen (1997, p. 23) points out that in earlier times Judaism (see Deuteronomy 18:20) and Christianity (see Acts 3:23) also regarded apostasy as a capital offense, but of the Abrahamic faiths, Islam stands alone in its inability to renounce this barbaric doctrine convincingly. The Koran does not explicitly commend killing apostates, but the hadith literature (the narrations of the life of the Prophet) certainly does. Most Muslims, I would guess, are sincere in their insistence that the hadith injunction that apostates are to be killed is to be disregarded, but it's disconcerting, to say the least, that fear of being regarded as an apostate is apparently a major motivation in the Islamic world. As Jansen puts it, "There can be no Hare Krishna or Baghwan, no Scientology, Mormonism or Transcendental Meditation in Mecca or Cairo. Within the world of Islam religious renewal has to steer clear of anything that implies or suggests apostasy" (pp. 88-89). So it is not just we outsiders who are left guessing. Even Muslims "on the inside" really don't know what Muslims think about apostasy — they mostly aren't prepared to bet their lives on it, which is the surest sign of belief, as we saw in chapter 8.

Here, then, we see a different face of the epistemological problem we encountered in chapter 8, on belief in belief. There we discovered that it is all but impossible to distinguish those who genuinely believe and those who (merely) believe in belief, since the beliefs in question are conveniently removed from the world of action. Now we see that one reason, free-floating or not, for such systematically masked creeds is to avoid — or at least postpone — the collision between contradictory creeds that would otherwise oblige the devout to behave far more intolerantly than most people today want to behave. (It is always worth reminding ourselves that not so very long ago people were banished, tortured, and even executed for heresy and apostasy in the most "civilised" corners of Christian Europe.)

So what is the prevailing attitude today among those who call themselves religious but vigorously advocate tolerance? There are three main options, ranging from the disingenuous Machiavellian —

1. As a matter of political strategy, the time is not ripe for candid declarations of religious superiority, so we should temporize and let sleeping dogs lie in hopes that those of other faiths can gently be brought around over the centuries.
— through truly tolerant Eisenhowerian "Our government makes no sense unless it is founded on a deeply held religious belief — and I don't care what it is" —

2. It really doesn't matter which religion you swear allegiance to, as long as you have some religion.
— to the even milder Moynihanian benign neglect —

3. Religion is just too dear to too many to think of discarding, even though it really doesn't do any good and is simply an empty historical legacy we can afford to maintain until it quietly extinguishes itself sometime in the distant and unforeseeable future.

It is no use asking people which they choose, since both extremes are so undiplomatic we can predict in advance that most people will go for some version of ecumenical tolerance whether they believe it or not. (It's just like Sir Maurice Oldfield's predictable denunciation of my subversive hypothesis about Kim Philby.)

We've got ourselves caught in a hypocrisy trap, and there is no clear path out. Are we like the families in which the adults go through all the motions of believing in Santa Claus for the sake of the kids, and the kids all pretend still to believe in Santa Claus so as not to spoil the adults' fun? If only our current predicament were as innocuous and even comical as that! In the adult world of religion, people are dying and killing, with the moderates cowed into silence by the intransigence of the radicals in their own faiths, and many afraid to acknowledge what they actually believe for fear of breaking Granny's heart, or offending their neighbours to the point of getting run out of town, or worse.

If this is the precious meaning our lives are vouchsafed thanks to our allegiance to one religion or another, it is not such a bargain, in my opinion. Is this the best we can do? Is it not tragic that so many people around the world find themselves enlisted against their will in a conspiracy of silence, either because they secretly believe that most of the world's population is wasting their lives in delusion (but they are too tenderhearted — or devious — to say so), or because they secretly believe that their own tradition is just such a delusion (but they fear for their own safety if they admit it)?

What alternatives are there? There are the moderates who revere the tradition they were raised in, simply because it is their tradition, and who are prepared to campaign, tentatively, for the details of their tradition simply because, in the marketplace of ideas, somebody should stick up for each tradition until we can sort out the good from the better and settle for the best we can find, all things considered. This is like allegiance to a sports team, and it, too, can give meaning to a life — if not taken too seriously. I am a Red Sox fan simply because I grew up in the Boston area and have happy memories of Ted Williams and Jimmy Piersall and Jackie Jensen and Carl Yastrzemski and Wade Boggs and Luis Tiant and Pudge Fisk, among others. My allegiance to the Red Sox is enthusiastic, but cheerfully arbitrary and undeluded. The Red Sox aren't my team because they are, in fact, the Best; they are "the Best" (in my eyes) because they are my team. I bask in the glory of their victory in 2004 (which was, of course, the Most Amazing and Inspiring Come-from-Behind Saga Ever), and if the team were ever to disgrace itself, I would be not just deeply chagrined but personally ashamed — as if I had something to do with it. And of course I do have something to do with it; my tiny personal contribution to the ocean of local enthusiasm and pride actually does buoy the players' spirits (as they always insist).

This is a kind of love, but not the rabid love that leads people to lie, and torture, and kill. Those who feel guilty contemplating "betraying" the tradition they love by acknowledging their disapproval of elements within it should reflect on the fact that the very tradition to which they are so loyal — the "eternal" tradition introduced to them in their youth — is in fact the evolved product of many adjustments firmly but delicately made by earlier lovers of the same tradition.

3. What can we say about sacred values?

We are here on Earth to do good to others. What the others are here for, I don't know. — W. H. Auden

For many years now, you and I have been shushed like children and told there are no simple answers to the complex problems that are beyond our comprehension. Well, the truth is there are simple answers. They are just not easy ones. — Ronald Reagan, inaugural address as governor of California, January 1977

If our tribalism is ever to give way to an extended moral identity, our religious beliefs can no longer be sheltered from the tides of genuine inquiry and genuine criticism. It is time we realized that to presume knowledge where one has only pious hope is a species of evil. Wherever conviction grows in inverse proportion to its justification, we have lost the very basis of human cooperation. — Sam Harris, The End of Faith

In order to adopt such a moderate position, however, you have to loosen your grip on the absolutes that are apparently one of the main attractions of many religious creeds. It isn't easy being moral, and it seems to be getting harder and harder these days. It used to be that most of the world's ills — disease, famine, war — were quite beyond the capacities of everyday people to ameliorate. There was nothing they could do about it, and since "'ought' implies 'can,'" people could ignore the catastrophes on the other side of the globe — if they even knew about them — with a clear conscience, since they were powerless to avert them in any way. Living by a few simple, locally applicable maxims could more or less guarantee that one lived about as good a life as was possible at the time. No longer.

Thanks to technology, what almost anybody can do has been multiplied a thousandfold, and our moral understanding about what we ought to do hasn't kept pace (Dennett, 1986, 1988). You can have a test-tube baby or take a morning-after pill to keep from having a baby; you can satisfy your sexual urges in the privacy of your room by downloading Internet pornography, and you can copy your favorite music for free instead of buying it; you can keep your money in secret offshore bank accounts and purchase stock in cigarette companies that are exploiting impoverished Third World countries; and you can lay minefields, smuggle nuclear weapons in suitcases, make nerve gas, and drop "smart bombs" with pinpoint accuracy. Also, you can arrange to have a hundred dollars a month automatically sent from your bank account to provide education for ten girls in an Islamic country who otherwise would not learn to read and write, or to benefit a hundred malnourished people, or provide medical care for AIDS sufferers in Africa. You can use the Internet to organize citizen monitoring of environmental hazards, or to check the honesty and performance of government officials — or to spy on your neighbors. Now, what ought we to do?

In the face of these truly imponderable questions, it is entirely reasonable to look for a short set of simple answers. H. L. Mencken cynically said, "For every complex problem, there is a simple answer . . . and it is wrong." But maybe he was wrong! Maybe one Golden Rule or Ten Commandments or some other short list of absolutely nonnegotiable Dos and Don'ts resolves all the predicaments just fine, once you figure out how to apply them. Nobody would deny, however, that it is far from obvious how any of the favored rules or principles can be interpreted to fit all our quandaries. As Scott Atran points out, the commandment "Thou shalt not kill" is cited by religious opponents of the death penalty, and by religious proponents as well (2002, p. 253). The principle of the Sanctity of Human Life sounds bracingly clear and absolute: every human life is equally sacred, equally inviolable; as with the king in chess, no price can be placed on it — aside from "infinity," since to lose it is to lose everything. But in fact we all know that life isn't, and can't be, like chess. There are multitudes of interfering "games" going on at once. What are we to do when more than one human life is at stake? If each life is infinitely valuable and none more valuable than another, how are we to dole out the few transplantable kidneys that are available, for instance? Modern technology only exacerbates the issues, which are ancient. Solomon faced tough choices with notable wisdom, and every mother who has ever had less than enough food for her own children (let alone her neighbour's children) has had to confront the impracticality of applying the principle of the Sanctity of Human Life.

Surely just about everybody has faced a moral dilemma and secretly wished, "If only somebody — somebody I trusted — could just tell me what to do!" Wouldn't this be morally inauthentic? Aren't we responsible for making our own moral decisions? Yes, but the virtues of "do it yourself" moral reasoning have their limits, and if you decide, after conscientious consideration, that your moral decision is to delegate further moral decisions in your life to a trusted expert, then you have made your own moral decision. You have decided to take advantage of the division of labor that civilisation makes possible and get the help of expert specialists.

We applaud the wisdom of this course in all other important areas of decision-making (don't try to be your own doctor; the lawyer who represents himself has a fool for a client, and so forth). Even in the case of political decisions, like which way to vote, the policy of delegation can be defended. When my wife and I go to Town Meeting, I know that she has studied the issues that confront our town so much more assiduously than I have that I routinely follow her lead, voting the way she tells me to vote, even if I'm not sure just why, because I have plenty of evidence for my conviction that if we did take the time and energy to thrash it all out she'd persuade me that, all things considered, her opinion was correct. Is this a dereliction of my duties as a citizen? I don't think so, but it does depend on my having good grounds for trusting her judgment. Love is not enough. That's why those who have an unquestioning faith in the correctness of the moral teachings of their religion are a problem: if they themselves haven't conscientiously considered, on their own, whether their pastors or priests or rabbis or imams are worthy of this delegated authority over their own lives, then they are in fact taking a personally immoral stand.

This is perhaps the most shocking implication of my inquiry, and I do not shrink from it, even though it may offend many who think of themselves as deeply moral. It is commonly supposed that it is entirely exemplary to adopt the moral teachings of one's own religion without question, because — to put it simply — it is the word of God (as interpreted, always, by the specialists to whom one has delegated authority). I am urging, on the contrary, that anybody who professes that a particular point of moral conviction is not discussable, not debatable, not negotiable, simply because it is the word of God, or because the Bible says so, or because "that is what all Muslims [Hindus, Sikhs . . . ] believe, and I am a Muslim [Hindu, Sikh . . . ]," should be seen to be making it impossible for the rest of us to take their views seriously, excusing themselves from the moral conversation, inadvertently acknowledging that their own views are not conscientiously maintained and deserve no further hearing.

The argument for this is straightforward. Suppose I have a friend, Fred, who is (in my carefully considered opinion) always right. If I tell you I'm against stem-cell research because "my friend Fred says it's wrong and that's all there is to it," you will just look at me as if I was missing the point of the discussion. This is supposed to be a consideration of reasons, and I have not given you a reason that I in good faith could expect you to appreciate. Suppose you believe that stem-cell research is wrong because that is what God has told you. Even if you are right — that is, even if God does indeed exist and has, personally, told you that stem-cell research is wrong — you cannot reasonably expect others who do not share your faith or experience to accept this as a reason. You are being unreasonable in taking your stand. The fact that your faith is so strong that you cannot do otherwise just shows (if you really can't) that you are disabled for moral persuasion, a sort of robotic slave to a meme that you are unable to evaluate. And if you reply that you can but you won't consider reasons for and against your conviction (because it is God's word, and it would be sacrilegious even to consider whether it might be in error), you avow your willful refusal to abide by the minimal conditions of rational discussion. Either way, your declarations of your deeply held views are posturings that are out of place, part of the problem, not part of the solution, and we others will just have to work around you as best we can.

Notice that this stand involves no disrespect and no prejudging of the possibility that God has told you. If God has told you, then part of your problem is convincing others, to whom God has not (yet) spoken, that this is what we ought to believe. If you refuse or are unable to attempt this, you are actually letting your God down, in the guise of demonstrating your helpless love. You can withdraw from the discussion if you must — that is your right — but then don't expect us to give your view any particular weight that we cannot discover by other means — and don't blame us if we don't "get it."

Many deeply religious people have all along been eager to defend their convictions in the court of reasonable inquiry and persuasion. They will have no difficulty at all with these observations — aside from confronting the diplomatic decision of whether they will join me in trying to convince their less reasonable coreligionists that they are making matters worse for their religion by their intransigence. And here is one of the most intractable moral problems confronting the world today. Every religion — aside from a negligible scattering of truly toxic cults — has a healthy population of ecumenical-minded people who are eager to reach out to people of other faiths, or no faith at all, and consider the moral quandaries of the world on a rational basis. In July 2004, the fourth Parliament of World Religions was held in Barcelona,3 and it brought thousands of people of different religions together for a week of workshops, symposia, plenary sessions, performances, and worship services, all enjoined to observe the same principles:

listen and be listened to so that all speakers can be heard speak and be spoken to in a respectful manner develop or deepen mutual understanding learn about the perspective of others and reflect on one's own views, and discover new insights. [Pathways to Peace, the Parliament program]

Colorful flocks of differently robed priests and gurus, nuns and monks, choirs and dancers, all holding hands and listening respectfully to one another — it was all very heartwarming, but these well-intentioned and energetic people are singularly ineffective in dealing with the more radical members of their own faiths. In many instances they are, rightly, terrified of them. Moderate Muslims have so far been utterly unable to turn the tide of Islamic opinion against Wahhabists and other extremists, but moderate Christians and Jews and Hindus have been equally feckless in countering the outrageous demands and acts of their own radical elements.

It is time for the reasonable adherents of all faiths to find the courage and stamina to reverse the tradition that honors helpless love of God — in any tradition. Far from being honorable, it is not even excusable. It is shameful. And most shameful are the priests, rabbis, imams, and other experts whose response to the sincere requests from their flock for moral guidance is to conceal their own inability to give reasons for their views about the tough issues by hiding behind some "inerrant" (read "above criticism") interpretation of the sacred texts. It is one thing for a well-meaning layperson with a deep allegiance to a religious tradition to delegate authority to his or her religious leaders, but it is quite another for those leaders to pretend to discover (thanks to their expertise) the right answers in their tradition by a process that has to be taken on faith and is inaccessible to even the most well-meant criticism.

As so often before, we should grant that it is entirely possible that this evasive question-ducking rationale is entirely free-floating. In other words, it is surely possible for people to believe in all innocencethat their love of God absolves them from the responsibility to figure out reasons for these hard-to-fathom commands from their beloved God. We need make no accusations of insincerity or guile, but respecting someone's innocence does not oblige us to respect his belief. Here is what we should say to such a person: There is only one way to respect the substance of any purported God-given moral edict: consider it conscientiously in the full light of reason, using all the evidence at our command. No God that was pleased by displays of unreasoning love would be worthy of worship.

Here is a riddle: how is your religion like a swimming pool? And here is the answer: it is what is known in the law as an attractive nuisance. The doctrine of attractive nuisance is the principle that people who maintain on their property a dangerous condition that is likely to attract children are under a duty to post a warning or to take stronger affirmative action to protect children from the dangers of that attraction. It is an exception to the general rule that no particular care is required of property owners to safeguard trespassers from harm. Unenclosed swimming pools are the bestknown example, but old refrigerators with their doors not removed, machinery or stacks of building materials, or other eminently climbable objects that could be an irresistible lure to young children have also been deemed attractive nuisances. Property owners are held responsible for harms that result when they maintain something that can lure innocent people into harm.

Those who maintain religions, and take steps to make them more attractive, must be held similarly responsible for the harms produced by some of those whom they attract and provide with a cloak of respectability. Defenders of religion are quick to point out that terrorists typically have political, not religious agendas, which may well be true in many or most cases, or even in all cases, but that is not the end of it. The political agendas of violent fanatics often lead them to adopt a religious guise, and to exploit the organizational infrastructure and tradition of unquestioning loyalty of whichever religion is handy. And it is true that these fanatics are rarely if ever inspired by, or guided by, the deepest and best tenets in those religious traditions. So what? Al Qaeda and Hamas terrorism is still Islam's responsibility, and abortion-clinic bombing is still Christianity's responsibility, and the murderous activities of Hindu extremists are still Hinduism's responsibility.

As Sam Harris argues in his brave book The End of Faith (2004), there is a cruel Catch-22 in the worthy efforts of the moderates and ecumenicists in all religions: by their good works they provide protective coloration for their fanatical coreligionists, who quietly condemn their open-mindedness and willingness to change while reaping the benefits of the good public relations they thereby obtain. In short, the moderates in all religions are being used by the fanatics, and should not only resent this; they should take whatever steps they can find to curtail it in their own tradition. Probably nobody else can do it, a sobering thought:

If a stable peace is ever to be achieved between Islam and the West, Islam must undergo a radical transformation. This transformation, to be palatable to Muslims, must also appear to come from Muslims themselves. It does not seem much of an exaggeration to say that the fate of civilization lies largely in the hands of "moderate" Muslims. [Harris, 2004, p. 154]

We must hold these moderate Muslims responsible for reshaping their own religion — but that means we must equally hold moderate Christians and Jews and others responsible for all the excesses in their own traditions. And, as George Lakoff has noted, we need to prove to those Islamic leaders that we hear their moral voices, and not just our own:

We depend on the goodwill and courage of moderate Islamic leaders. To gain it, we must show our goodwill by beginning in a serious way to address the social and political conditions that lead to despair. [2004, p. 61]

How can we all keep the cloak of religious respectability from being used to shelter the lunatic excesses? Part of the solution would be to make religion in general less of a "sacred cow" and more of a "worthy alternative." This is the course somewhat haplessly followed by some of us brights — atheists, agnostics, freethinkers, secular humanists, and others who have liberated themselves from specifically religious allegiances. We brights are quite aware of all the good that religions accomplish, but we prefer to channel our charity and good deeds through secular organizations, precisely because we don't want to be complicit in giving a good name to religion! This keeps our hands clean, but that is not enough — any more than it is enough for moderate Christians to avoid giving funds to anti-Semitic organizations within Christianity, or for moderate Jews to restrict their charity to organizations that are working to secure peaceful coexistence for Palestinians and Israelis. That is a start, but there is more work to be done, and it is the unpleasant and even dangerous work of desanctifying the excesses in each tradition from the inside. Any religious person who is not actively and publicly involved in that effort is shirking a duty — and the fact that you don't belong to a congregation or denomination that is offending doesn't excuse you: it is Christianity and Islam and Judaism and Hinduism (for example) that are attractive nuisances, not just their offshoot sects.

Any vicious cult that uses Christian imagery or texts as its protective coloration should lie heavily on the conscience of all who call themselves Christians, for instance. Until the priests and rabbis and imams and their flocks explicitly condemn by name the dangerous individuals and congregations within their ranks, they are all complicit. I know many Christians who are privately sickened by many of the words and deeds done "in the name of Jesus," but expressions of dismay to close friends are not enough. In Darwin's Dangerous Idea, I wrote about the brave Muslims who dared to speak out publicly against the obscene travesty of the fatwa pronounced on Salman Rushdie, author of The Satanic Verses, condemned to death for his heresies, and urged, "Let us all distribute the danger by joining hands with them" (p. 517n). But here is the truly distressing Catch-22: if we non-Muslims join hands with them, we thereby mark them as "puppets of the enemies of Islam" in the eyes of many Muslims. Only those within the religious community can effectively start to dismantle this deeply immoral attitude, and multiculturalists who urge us to go easy on them are exacerbating the problem.

4. Bless my soul: spirituality and selfishness

He who has the most toys when he dies wins. — Well-known materialist slogan

Yes, we have a soul; but it's made of lots of tiny robots. — My materialist slogan 

Consider the two utterly different meanings of the word "materialistic." In its most common everyday sense, it refers to somebody who cares only about "material" possessions, wealth, and all its trappings. In its scientific or philosophical sense, it refers to a theory that aspires to explain all the phenomena without recourse to anything immaterial — like a Cartesian soul, or "ectoplasm" — or God. The standard negation of materialistic in the scientific sense is dualistic, which maintains that there are two entirely different kinds of substance, matter and . . . whatever minds are supposedly made of. The apparent bridge tying the two meanings together is obvious enough: if you don't think you have an immortal soul, then you don't believe you'll get your reward in heaven, so . . . you might as well go for whatever you can get in this material world. If we asked people what term was the negation of materialistic in the everyday sense, they might very well settle on spiritual.

In the course of my research on this book, I found one opinion expressed in slightly different ways by people across the spectrum of religious views: "man" has a "deep need" for "spirituality," a need that is fulfilled for some by traditional organized religion, for others by New Age cults or movements or hobbies, and for still others by the intense pursuit of art or music, pottery or environmental activism — or football! What fascinates me about this delightfully versatile craving for "spirituality" is that people think they know what they are talking about, even though — or perhaps because — nobody bothers to explain just what they mean. It is supposed to be obvious, I guess. But it really isn't. When I've asked people to explain themselves, they typically beg off, along the lines of Louis Armstrong's oft-quoted reply when asked what jazz was: "If you gotta ask, you ain't never gonna get to know." This will not do. To see for yourself just how hard it is to say what spirituality is, take a stab at improving on this parody, boiled down from many frustrating encounters: "Spirituality is, you know, like, it's like paying attention to your soul or having deep thoughts that really move you, and not just thinking about who's got nicer clothes and whether to buy a new car and what's for dinner and stuff like that. Spirituality is really caring and not being just, you know, materialistic."Along with this common and unreflective view of spirituality goes a stereotype of the atheist: atheists lack "values"; they are careless, self-centered, shallow, overconfident. They think they know it all, and yet they completely miss out on the spirit. (You really can't be a good person unless you have a spiritual life.)

Now let me try to put better words in their mouths. What these people have realized is one of the best secrets of life: let your self go. If you can approach the world's complexities, both its glories and its horrors, with an attitude of humble curiosity, acknowledging that however deeply you have seen, you have only just scratched the surface, you will find worlds within worlds, beauties you could not heretofore imagine, and your own mundane preoccupations will shrink to proper size, not all that important in the greater scheme of things. Keeping that awestruck vision of the world ready to hand while dealing with the demands of daily living is no easy exercise, but it is definitely worth the effort, for if you can stay centered, and engaged, you will find the hard choices easier, the right words will come to you when you need them, and you will indeed be a better person. That, I propose, is the secret to spirituality, and it has nothing at all to do with believing in an immortal soul, or in anything supernatural.

The psychologist Nicholas Humphrey has explored in some depth the relationship between belief in "psychic forces" and the everyday sense of morality. He notes that almost all stories of the paranormal, of extrasensory perception and clairvoyance and talking to deceased friends and relatives at seances, have a "somewhat self-righteous aura to them — a tag of holiness, a certain touch-menot feel" (1995, p. 186). And although this may be due in part to the fact that so often the stories deal with the most emotionally sensitive areas of people's lives, he has another explanation:

. . . it originates with what is, arguably, one of the most remarkable confidence tricks our culture has played on us. This has been to persuade people that there is a deep connection between believing in the possibility of psychic forces and being a gracious, honest, upright, trustworthy member of society....

He deftly enunciates the free-floating rationale:

Whether or not people have had any explicit religious education, they have all been exposed to the idea that some kind of supernatural parent figure watches over them and cares for them. It may easily follow therefore that people's sense of justice and propriety persuades them that, if such a figure does exist, then not to believe in him would be ungrateful in the extreme — and only wicked children could possibly be so ungrateful. But, if unbelievers are generally wicked, it is natural (though hardly logical) to assume that believers are generally good. So whether or not a person believes in this supernatural parent becomes in itself a measure of his moral virtue.... The absurd, but quite widely accepted result has been that every paranormal story we hear is supposed to be automatically worthy of attention and respect. [pp. 186-87]

I have come to accept that this alignment of moral goodness with "spirituality" and moral evil with "materialism" is just a frustrating fact of life, so deeply rooted in our contemporary conceptual scheme that it amounts to a prevailing wind against which materialistic science has to strain. We materialists are the bad guys, and those who believe in anything supernatural, however goofy and gullible the particular belief, have at least this much going for them: they're "on the side of the angels."

This familiar phrase was born, by the way, in the Oxford Union, a debating society at Oxford University, in a speech by Benjamin Disraeli in 1864, in response to the challenge of Darwinism:

"What is the question now placed before society with a glib assurance the most astounding? The question is this — Is man an ape or an angel. My Lord, I am on the side of the angels." 

The misalignment of goodness with the denial of scientific materialism has a long history, but it is a misalignment.5 There is no reason at all why a disbelief in the immateriality or immortality of the soul should make a person less caring, less moral, less committed to the well-being of everybody on Earth than somebody who believes in "the spirit." But won't such a materialist care only about the material well-being of the people? If that means only their housing, their car, their food, their "physical" as opposed to "mental" health, no. After all, a good scientific materialist believes that mental health — spiritual health, if you like — is just as physical, just as material, as "physical" health. A good scientific materialist can be just as concerned about whether there is plenty of justice, love, joy, beauty, political freedom, and, yes, even religious freedom as about whether there is plenty of food and clothing, for instance, since all of these are material benefits, and some are more important than others. (But for goodness' sake, let's try to get food and clothing to everybody who needs them as soon as possible, since without them justice and art and music and civil rights and the rest are something of a mockery.)

That should correct the understandable logical confusion. There is also the factual misconception to correct: plenty of "deeply spiritual" people — and everybody knows this — are cruel, arrogant, selfcentered, and utterly unconcerned about the moral problems of the world. Indeed, one of the truly nauseating side effects of the common confusion of moral goodness with "spirituality" is that it permits untold numbers of people to slack off on the sacrifice and good works and hide behind their unutterably sacred (and impenetrable) mask of piety and moral depth. It's not just the hypocrites, though there are always plenty of them around. There are many people who quite innocently and sincerely believe that if they are earnest in attending to their own personal "spiritual" needs, this amounts to living a morally good life. I know many activists, both religious and secular, who agree with me: these people are deluding themselves. Auden's sardonic quip may shake our faith in the obviousness of the imperative to help others, but it certainly does nothing to suggest that just taking care of one's own "soul" is anything but selfish. Consider, for instance, those contemplative monks, primarily in Christian and Buddhist traditions, who, unlike hardworking nuns in schools and hospitals, devote most of their waking hours to the purification of their souls, and the rest to the maintenance of the contemplative lifestyle to which they have become accustomed. In what way, exactly, are they morally superior to people who devote their lives to improving their stamp collections or their golf swing? It seems to me that the best that can be said of them is that they manage to stay out of trouble, which is not nothing.

I am under no illusions about how hard it will be to undo the centuries of presumption that tend to merge "spirit" and "goodness." Since "team spirit" is obviously good, how can the denial of "spirit"be anything but bad? Even deep in the trenches of cognitive neuroscience, I find annoying echoes and shadows of this prejudice, with us "hardheaded" materialists forever on the defensive against the now practically extinct species of "tenderhearted" dualists, who seem (to the laypeople at least) to occupy the moral high ground simply because they still believe in the immateriality of souls. It's an uphill battle, but perhaps it will go better for us when it is fought in broad daylight.

But what about that hunger for spirituality that so many of my informants think is the mainspring of religious allegiance? The good news is that people really do want to be good. Believers and brights alike deplore the crass materialism (everyday sense) of popular culture and yearn not just to enjoy the beauty of genuine love but to bring that joy to others. It may often have been true in the past that for most people the only available road to that fulfilment involved a commitment to the supernatural, and more particularly to a specific institutional version of the supernatural, but today we can see that there is a bounty of alternative highways and footpaths to consider.

Chapter 10 The widely prevailing opinion that religion is the bulwark of morality is problematic at best. The idea that heavenly reward is what motivates good people is demeaning and unnecessary; the idea that religion at its best gives meaning to a life is jeopardized by the hypocrisy trap into which we have fallen; the idea that religious authority grounds our moral judgments is useless in genuine ecumenical exploration; and the presumed relation between spirituality and moral goodness is an illusion.

Chapter 11 The research described in this book is just the beginning. Further research is needed, on both the evolutionary history of religion and on its contemporary phenomena, as they appear to different disciplines. The most pressing questions concern how we should deal with the excesses of religious upbringing and the recruitment of terrorists, but these can only be understood against a background of wider theories of religious conviction and practice. We need to secure our democratic society, the home base for this research, against the subversions of those who would use democracy as a ladder to theocracy and then throw it away, and we need to spread the knowledge that is the fruit of free inquiry.
