Notes on "Morality without religion has no firm foundation"

Here are some notes I used for the debate: “Morality without religion has no firm foundation”

Notice the focus of this debate is not on god. God gets no mention. The question is specifically about religion. The question before us is: can morality have a firm foundation in the absence of religion. And so it’s on religion that I shall focus.

I think the answer is pretty clearly yes – morality can have at least as firm a foundation in the absence of religion as it can with it.

I want to start by outlining an alternative, non-religious approach to morality which I think is preferable to most traditional, religious approaches.

What are the characteristics of humanism?

1. First, humanists don’t believe in a God. They are atheists, or at least agnostics.

2. Secondly, humanists, like many sensible religious folk, are secularists. They favour an open, democratic society in which the state takes a neutral position with respect to religion.

3. Thirdly, humanists sign up to the idea that morality should focus on achieving human flourishing in this life, rather than on achieving fulfilment in some mythical life-to-come. Obviously they deny that morality is a matter of obeying the commands of supernatural beings, or doing good because of threats of divine punishment. However, there is no specific humanist theory of moral value. Some humanists are utilitarians, but plenty are not. Some are Kantians. And some even reject naturalism.

4. Fourthly, humanists believe in the importance of a certain kind of moral autonomy. They believe people should be encouraged to think and question, and ultimately make their own judgements about what is right or wrong, rather than defer to some external authority – be it religious or political – that will make the judgement for them.

Religions, by contrast, have typically placed far greater emphasis on deference to authority – to a text, a prophet, a leader, or a tradition whose pronouncements are to be accepted more or less without question.

Of course there are plenty of fairly liberal-minded clerics around today who would sign up to the Enlightenment ideal, but many don’t.

The mainstream religions have long track record of attempting to stifle dissent, shutting down and censoring criticism. Of dissuading children from asking certain sorts of “difficult” question.

A friend of mine, no longer a Catholic, tells me that, even today, half a century after her education at the hands of a traditional Catholic school, she still feels guilty if she dares to question a Catholic belief.

Many religions have, historically, focused on instilling such unquestioning, deferential attitudes among the faithful. In many places, they still do.

Visit the US Bible belt and you will find church signs that read “A free thinker is Satan’s slave”.

Indeed, Christian Churches have a long track record of attempting to stifle dissent and criticism by violent means.

Holy Inquisition last victim. Ancient history! Actually, the last victim died in 1824 – just over four of my lifetimes ago. Our freedom to question or reject religious teaching is a very recently won and precious freedom that we shouldn’t just assume will now be around forever.

And of course we’re not just talking about Christian obsession with thought-control. A poll conducted a few years ago of Young British Muslims found that 33% of them thought the appropriate penalty for anyone who leaves the Muslim faith is death.

Even today, several Muslim theocracies will execute anyone who leaves the Muslim faith.

Of course, atheists, too, have had a violent obsession with policing people’s thoughts. Stalin, Mao and Pol Pot were all concerned with forcing atheism on people.

But of course, Stalin, Mao and Pol Pot, while atheists, weren’t humanists. They certainly didn’t value moral autonomy – on encouraging individuals to think and question, any more than did the Holy Inquisition. You can’t blame humanism for the killing fields of Cambodia.

Now here’s what I think is an important advantage of a humanist approach to moral education over both authoritarian atheist approaches and traditional religious approaches.

It’s sometimes said that what motivated those who helped rescue Jews during the Holocaust was their religious conviction. In fact, religious conviction had little….

Philosopher Jonathan Glover says:

If you look at the people who shelter Jews under the Nazis, you find a number of things about them. One is that they tended to have a different kind of upbringing from the average person, they tended to be brought up in a non-authoritarian way, bought up to have sympathy with other people and to discuss things rather than just do what they were told.

Oliners: it was on their emphasis on reasoning in talking about morality with their children that marked out rescuers from non-rescuers. By contrast, the Oliners found that “religiosity was only weakly related to rescue”.

So, if we want to immunize future generations against this sort of moral catastrophe, this evidence at least suggest that our best bet is NOT to rely on religion, but on an approach to moral education that, as it happens, is promoted by humanism.

Evidence that in fact it’s not a religious upbringing that’s required for a firm moral foundation, but the kind of philosophical approach promoted and practices by humanists.

Of course, there are plenty of liberal-minded religious folk who would endorse humanist view. So I don’t say this is an advantage over every form of religious upbringing. But it is far better, I’d suggest, than many forms of traditional religious upbringing - those that, too this day, still tend to dominate around much of the world.

In fact, what many religions encourage people to do cannot be done. Convenient though it might be, I cannot hand over responsibility for making moral judgements to some text, or prophet, or tradition. For suppose my chosen religious moral expert tells me to do some dreadful thing – to go a blow myself up in a supermarket, or slaughter every last Canaanite, say.

Clearly, if I do as I am told, I remain culpable. I can’t absolve myself of responsibility, by saying “But I was just obeying orders”, as I could if I’d been given bad chemical or medical advice, say. Morality is different. We all have an unavoidable responsibility to think and make our own judgement. It’s worth listening to others, even to religious people, for their advice. But, like it or not, you must take responsibility for making the judgements you do.

You have to choose which religion if any to follow, which interpretation of that religion, which leader, and so on. You have to decide whether you ought to follow the advice they give you. And in making that judgement you inevitably have to rely on your own moral compass.

So, like it or not, we do all have to make our own moral judgements. The supposed “firm foundation” that religions provide in the form of ancient texts, or gurus, or prophets, or religions, or traditions, to which can turn for moral certainties, are really not firm at all.

At the end of the day, we all - religious or not - have to make our own moral judgements, relying on our own moral intuitions and sense of what is right and wrong – which are themselves open to question. Better we face up to this fact rather than pretend it is not so.

But isn’t it clear that loss of religion has caused a great many social ills? That religion is necessary if morality is to flourish properly?

No. There’s no good evidence to support that view.

LOSS OF RELIGION HAS CAUSED SOCIAL PROBLEMS

1. Co-occurrence doesn’t establish causal connection. Many other changes: homes stand empty. People don’t know their neighbours or community.

2. 200 years ago 50 times more crime in UK than there is now. Yet far more religious.

3. When we look across world’s developed democracies, we find that those that are most religious – including, of course, the United States (where 43% of citizens claim to attend church weekly) – have the highest rates of homicide, sexually transmitted disease (STD), teen pregnancy and abortion. The least religious countries, such as Canada, Japan and Sweden, have the lowest rates.

4. As historian Francis Fukuyama points out, China also provides an important counter-example to the view that moral order depends on religion:

The dominant cultural force in traditional Chinese society was, of course, Confucianism, which is not a religion at all but rather a rational, secular ethical doctrine. The history of China is replete with instances of moral decline and moral renewal, but none of these is linked particularly to anything a Westerner would call religion. And it is hard to make the case that levels of ordinary morality are lower in Asia than in parts of the world dominated by transcendental religion.

5. To other cultures widespread Western assumption that people won’t be good without belief in God is baffling. Chinese writer Lin Yu Tang”:

To the West, it seems hardly imaginable that the relationship between man and man (morality) could be maintained without reference to a Supreme Being, while to the Chinese it is equally amazing that men should not, or could not, behave toward one another as decent beings without thinking of their indirect relationship through a third party.

6. Our basic morality is a pretty much universal feature of human societies, religious or not.

In many societies, morality has had little to do with religion, and yet those societies, while obviously not always perfect, have hardly been less moral than, say, their Christian or Muslim counterparts. Indeed, we find much the same basic morality.

Religion, it turns out, did not create morality. Rather, religions take a basic morality that is there anyway, probably written into our genes, and then rigidly codifies it and adds a few prohibitions of its own, usually concerning some foodstuffs and sexual practices. Then it says, “Voila! Religion has created morality!”

Economic quackery: the entirely illusory "skill" of the traders

A bit more on economic quackery. This is from an article published yesterday. The associated book by Kahneman looks very interesting. I previously noted this suspicious "skill". It's non-existent character is increasingly well-documented. But incredibly well rewarded!

Mutual funds are run by highly experienced and hardworking professionals who buy and sell stocks to achieve the best possible results for their clients. Nevertheless, the evidence from more than 50 years of research is conclusive: for a large majority of fund managers, the selection of stocks is more like rolling dice than like playing poker. Typically at least two out of every three mutual funds underperform the overall market in any given year.

More important, the year-to-year correlation between the outcomes of mutual funds is very small, barely higher than zero. The successful funds in any given year are mostly lucky; they have a good roll of the dice. There is general agreement among researchers that nearly all stock pickers, whether they know it or not – and few of them do – are playing a game of chance.

The subjective experience of traders is that they are making sensible educated guesses in a situation of great uncertainty. In highly efficient markets, however, educated guesses are no more accurate than blind guesses.

Some years ago I had an unusual opportunity to examine the illusion of financial skill up close. I had been invited to speak to a group of investment advisers in a firm that provided financial advice and other services to very wealthy clients. I asked for some data to prepare my presentation and was granted a small treasure: a spreadsheet summarising the investment outcomes of some 25 anonymous wealth advisers, for each of eight consecutive years. Each adviser's score for each year was his (most of them were men) main determinant of his year-end bonus. It was a simple matter to rank the advisers by their performance in each year and to determine whether there were persistent differences in skill among them and whether the same advisers consistently achieved better returns for their clients year after year.

To answer the question, I computed correlation coefficients between the rankings in each pair of years: year 1 with year 2, year 1 with year 3, and so on up through year 7 with year 8. That yielded 28 correlation coefficients, one for each pair of years. I knew the theory and was prepared to find weak evidence of persistence of skill. Still, I was surprised to find that the average of the 28 correlations was 0.01. In other words, zero. The consistent correlations that would indicate differences in skill were not to be found. The results resembled what you would expect from a dice-rolling contest, not a game of skill.

No one in the firm seemed to be aware of the nature of the game that its stock pickers were playing. The advisers themselves felt they were competent professionals doing a serious job, and their superiors agreed. On the evening before the seminar, Richard Thaler and I had dinner with some of the top executives of the firm, the people who decide on the size of bonuses.

We asked them to guess the year-to-year correlation in the rankings of individual advisers. They thought they knew what was coming and smiled as they said "not very high" or "performance certainly fluctuates". It quickly became clear, however, that no one expected the average correlation to be zero.

Our message to the executives was that, at least when it came to building portfolios, the firm was rewarding luck as if it were skill. This should have been shocking news to them, but it was not. There was no sign they disbelieved us. How could they? After all, we had analysed their own results, and they were sophisticated enough to see the implications, which we politely refrained from spelling out. We all went on calmly with our dinner, and I have no doubt that both our findings and their implications were quickly swept under the rug and that life in the firm went on as before. The illusion of skill is not only an individual aberration; it is deeply ingrained in their culture. Facts that challenge such basic assumptions – and thereby threaten people's livelihood and self-esteem – are simply not absorbed. The mind does not digest them. This is particularly true of statistical studies of performance, which provide base-rate information that people generally ignore when it clashes with their personal impressions from experience.

The next morning, we reported the findings to the advisers, and their response was equally bland. Their own experience of exercising careful judgment on complex problems was far more compelling to them than an obscure statistical fact. When we were done, one of the executives with whom I had dined the previous evening drove me to the airport. He told me, with a trace of defensiveness: "I have done very well for the firm and no one can take that away from me." I smiled and said nothing. But I thought: "Well, I took it away from you this morning. If your success was due mostly to chance, how much credit are you entitled to take for it?"

Cognitive illusions can be more stubborn than visual illusions. When my colleagues and I in the army learned that our leadership assessment tests had low validity, we accepted that fact intellectually, but it had no impact on either our feelings or our subsequent actions. The response we encountered in the financial firm was even more extreme. I am convinced that the message that Thaler and I delivered to both the executives and the portfolio managers was instantly put away in a dark corner of memory where it would cause no damage.

Why do investors, both amateur and professional, stubbornly believe that they can do better than the market, contrary to an economic theory that most of them accept, and contrary to what they could learn from a dispassionate evaluation of their personal experience? The most potent psychological cause of the illusion is certainly that the people who pick stocks are exercising high-level skills. They consult economic data and forecasts, they examine income statements and balance sheets, they evaluate the quality of top management, and they assess the competition. All this is serious work that requires extensive training. Unfortunately, skill in evaluating the business prospects of a firm is not sufficient for successful stock trading, where the key question is whether the information about the firm is already incorporated in the price of its stock. Traders apparently lack the skill to answer this crucial question, but they appear to be ignorant of their ignorance.

Britain's harmful "quack" economic cure

Editorial from the New York Times, Oct 14th.

For a year now, Britain’s economy has been stuck in a vicious cycle of low growth, high unemployment and fiscal austerity. But unlike Greece, which has been forced into induced recession by misguided European Union creditors, Britain has inflicted this harmful quack cure on itself.

Austerity was a deliberate ideological choice by Prime Minister David Cameron’s ruling coalition of Conservatives and Liberal Democrats, elected 17 months ago. It has failed and can be expected to keep failing. But neither party is yet prepared to acknowledge that reality and change course.

Britain’s economy has barely grown since the budget cuts began taking effect late last year. The most recent quarterly figures showed the economy flat-lining, with growth at 0.1 percent.

New figures released this week reported Britain’s highest jobless numbers in more than 15 years. Independent analysts expect unemployment — now 8.1 percent — to keep rising in the months ahead. The government has kept its promise to slash public-sector jobs — more than 100,000 have been lost in recent months. But its deficit-reduction policies have failed to revive the business confidence that was supposed to spur private-sector hiring.

Drastic public spending cuts were the wrong deficit-reduction strategy for the weakened British economy a year ago. And they are the wrong strategy for the faltering American economy today. Britain’s unhappy experience is further evidence that radical reductions in federal spending will do little but stifle economic recovery.

A few years of robust growth would go far toward making swollen federal deficits more manageable. But slashing government spending in an already stalled economy weakens anemic demand, leading to lost output and lost tax revenues. As revenues fall, deficit reduction requires longer, deeper spending cuts. Cut too far, too fast, and the result is not a balanced budget but a lost decade of no growth. That could now happen in Britain. And if the Republicans have their way, it could also happen here.

Austerity is a political ideology masquerading as an economic policy. It rests on a myth, impervious to facts, that portrays all government spending as wasteful and harmful, and unnecessary to the recovery. The real world is a lot more complicated. America has no need to repeat Mr. Cameron’s failed experiment.


[end]

Incidentally, here's a report about that Observer letter penned by 100 leading figures (incl economists) telling Osborne he needs a Plan B - Plan A has caused disaster (as was widely predicted).

Here are my thoughts on the "quackery" charge. As I've mentioned previously, the one thing to ask about any major Tory economic policy is: "Cui bono?" - who, primarily, benefits? And the answer is always exactly the same: the very rich and/or big business (or at least what they perceive to be in their self-interest: obviously it's not in their interest to screw the economy as they appear to have done).

I am open to persuasion that some right-wing economic policies are in the best-interests of the nation. But I can't see there's much evidence to support any such policies. At best, the evidence leaves it unclear whether any given preferred right-wing policy is better (and I notice that quite often the case "for" turns out to be articulated by people from "think-tanks" that are, in effect, little more than PR companies for the rich/big business guys that fund them).

Once we apply the "Cui bono?" test, it's very hard to avoid the conclusion that what primarily drives Tory economic policy is not evidence, per se, but what the rich and powerful perceive to be in their self-interest. Who, of course, ain't necessarily even that bright.

The "evidence" is then gerrymandered and cherry-picked to justify their preferred policies. Those who question it are accused of "outdated" thinking.

That is, indeed, quackery.

Thanks for all the feedback re WLC debate

Apologies if I do not respond to every comment. There have been a lot.

I'm genuinely grateful for all the feedback - positive and negative. I want to believe what's true, of course. So counter-arguments are to be welcomed - especially if they're good ones!

Apparently I will burn in hell for all eternity for failing to believe in Craig's God, if he exists. So would prefer not to get this wrong.

I'm in Sweden for a few days from tomorrow, so won't be posting much if at all.

POSTSCRIPT

I was asked to prepare some questions for Craig for the Q&A session at the end. In fact I was never given the opportunity to ask any. But I had prepared a couple. Here they are:

NUCLEAR QUESTION

You claim to just know in your heart, with utter certainty, that God exists and Christianity is true.

I want you to imagine that you have become President of the United States. Imagine also that there’s a red button on the table.

You know that pressing the button will bring about a nuclear holocaust, unleash unimaginable horror, and bring about a nuclear winter that will render humankind extinct with a decade or two.

It now suppose it seems to you that God wants you to press the button. In fact it seems as clearly and unambiguously true that this is what God wants you to do as it seems true to you that God exists.

My question is: what would be the reasonable thing for you to do, and why?

[p.s. I am pretty sure Craig would say "Press the button". Which is worrying. Let's hope he never stands for office.]

LYING QUESTION

You believe that every human knows in his or her heart that your God exists. So there’s no excuse for unbelief.

So am I just, well, lying when I say “There is no God”, and when I tell you I have no such inner knowledge? For, according to you, I'm telling you something that I know not to be true, right?

Follow up point: If I know God has not made himself known in my heart, but Craig’s God is one who makes himself known in every human heart, then I can know immediately that Craig’s God does not exist.

Prof Craig says he just knows his god exists. It turns out, that, if he's right, I can just know he doesn’t!

CELEBRITY WOO EXAMPLES QUICKLY PLEASE

Help needed. I quickly need some examples of celebrities buying into or endorsing, e.g. miracles cures, new age philosophers, psychics, mediums, ghost stories, homeopathy and other alt. medicines. Any examples and/or links of celebrity woo v gratefully received. Bigger the celebrity and the more recent the better.

Thanks!

My remaining notes from the Craig debate

Here are my remaining notes prepared for the debate on God's existence with William Lane Craig. These anticipated Craig's likely responses to my attacks on hos moral and resurrection arguments. I didn't really use this stuff on the night, except a little in Q&A session at the end. Notice I was also ready for the ontological argument.


2. CRAIG’S POSSIBLE DEFENCES OF MORAL ARGUMENT

IF NO GOD, THEN WE’RE NOT SPECIAL. WE’RE JUST ANIMALS, LIKE OTHER ANIMALS. THEY HAVE NO MORAL DUTIES TO EACH OTHER. SO NEITHER DO WE.

It doesn’t follow from the fact that we are animals that we are not special. We can still be, and are, special in all sorts of ways.

Unlike other animals we can write poetry, contemplate the great questions of philosophy, derive a profound sense of meaning and enjoyment from great works of art. We are rational agents capable of reflecting on the moral consequences of our actions.

In fact, it’s this last difference between us and other animals that explains why they’re not morally responsible but we are – why lions can’t murder, but we can.

I’m not insisting this fact is also sufficient to make us objectively morally significant. But Professor Craig has not explained why it isn’t.

IF NO GOD THEN NO OBJECTIVE MORAL VALUES BECAUSE – IF THERE’S NO GOD, THEN WE ALL END UP AS DUST, AND THE UNIVERSE ENDS IN HEAT DEATH, SO WHAT DOES IT ULTIMATELY MATTER HOW WE BEHAVE?

This is an obviously fallacious argument. Just because two roads end at the same destination doesn’t entail that it doesn’t matter which one we take. It doesn’t follow from the fact that we inevitably and permanently die that it doesn’t matter how we live. It does not follow from the fact that it doesn’t matter to how the universe ends how I treat you to, that it doesn’t matter how I treat you.

CRAIG SAYS THAT I REJECT BELIEF IN GOD ON THE BASIS OF APPEARANCE, YET WON’T ACCEPT THE EXISTENCE OF OBJECTIVE MORAL VALUES ON THE BASIS OF APPEARANCE. I AM IN EFFECT, GUILTY OF A DOUBLE STANDARD.

This is to overlook the fact that the appearance of immense gratuitous suffering, plus the assumption the appearance is reliable, immediately delivers the conclusion there’s no God, while the appearance of objective moral values, plus the assumption that the appearance is reliable, does not immediately deliver the conclusion there is a God. You need the further premise that if there’s no god there are no objective moral values. And that premise is (i) not obviously true, (ii) very widely rejected by moral philosophers, including even Christian philosophers. So, if we’re going to start trusting appearances, appearance is far more of a direct threat to theism than it is to atheism.

In addition, there’s a pretty good evolutionary explanation for why the appearance of objective moral value can’t be trusted.

IF THERE’S NO GOD THEN WE ARE JUST COLLECTIONS OF MOLECULES. WE CAN HAVE NO MORAL OBLIGATIONS TO COLLECTIONS OF MOLECULES.

Craig us here assuming that if we are collections of molecules then that’s all we are. But of course we are much more than that, even on a non-theistic view. We are collections of molecules that can write poetry, contemplate the great questions of philosophy, derive a profound sense of meaning and enjoyment from great works of art. We are also rational agents capable of reflecting on the moral consequences of our actions.

This, many philosophers would say, explains why we are special, why we matter, even if a mere glass of water does not. I cannot see how Professor Craig yet succeeded in showing this view to be wrong.

3. CRAIG’S POSSIBLE DEFENCES OF RESURRECTION ARGUMENT.

I USED A UFO CASE TO ILLUSTRATE THE POINT THAT WE SHOULD EXPECT A FEW BAFFLING, HARD TO EXPLAIN REPORTS TO CROP UP ANYWAY, WHETHER OR NOT THERE’S ANY TRUTH TO SUCH REPORTS. THE SAME GOES FOR MIRACLE CLAIMS. PROF CRAIG HAS ATTACKED MY SUGGESTION BY INSISTING HIS MIRACLE STORY IS NOT VERY LIKE MY UFO STORY.

Well, yes, obviously it isn’t. My UFO reports come directly from first-hand eye witnesses. Craig’s Biblical reports do not. My UFO story involved hard supporting data – a blip on a radar scope. Craig’s story lacks any such hard data. The reports I referred to came from police officers – trained eyewitnesses with no ideological axe to grind. Craig’s reports come via wide-eyed true believers about whom we know almost nothing.

Yes, of course there are differences between the cases. Pointing that out does nothing to undermine the moral I drew.


YOU MAY SAY I HAVE FAILED TO OFFER ANY DECENT ALTERNATIVE EXPLANATION OF WHAT WAS REPORTED.

True. But that’s entirely to overlook the fact that I explained why our inability to come up with an intuitively plausible-sounding mundane explanation of such reports doesn’t give us much reason to suppose a miracle happened.

THE DISCIPLES DIED FOR WHAT THEY BELIEVED. THE POLICEMEN DIDN’T.

Sure it may be hard to explain why early Christian would die for their beliefs if those beliefs weren’t true. But followers of even ludicrous new cults often go to their deaths – consider the followers of Heaven’s Gate and Jim Jones.



SECOND REBUTTAL – PART FOUR

4. ONTOLOGICAL ARGUMENT

It’s possible a maximally great being exists.

…Therefore, a maximally great being exists.

This argument has no force at all against the evidential problem of evil. In fact, ironically, it actually serves to reinforce my conclusion. For if I can use the evidential problem of evil to show there’s actually no god – that the conclusion of Craig’s ontological argument is false - then the validity of the argument entitles me to draw the further conclusion that’s it’s not even possible that god exists!

So my thanks to Professor Craig for furnishing me with an argument that serves actually to amplify my conclusion – allowing me to move from: there’s no god to: necessarily, there’s no god.

FOLLOW UP: I suppose Prof Craig might say: but there’s intuitive support for the first premise that it’s possible that a maximally great being exists. Such a being is conceivable. There’s no logical contradiction involved in supposing such a being exists. And that’s good reason to suppose such a being is metaphysically possible.

But as anyone familiar with developments in philosophical logic over the last half century can tell you, conceivability or imaginability provides no guarantee of metaphysical possibility. For example, though they are actually identical, it seems conceivable that the evening star is not the morning star. Yet, if they are identical at the actual world – and they are - then they’re identical at every possible world in which they exist. So, despite the fact that I can imagine or conceive of them not being identical, it’s not metaphysically possible for them to fail to be identical.
