Does the Universe Need God?

I’ve had God on my mind lately, as I’ve been finishing an invited essay for the upcoming Blackwell Companion to Science and Christianity. The title is “Does the Universe Need God?“, and you can read the whole thing on my website by clicking.

I commend the editors, Jim Stump and Alan Padgett, for soliciting a contribution that will go against the grain of most of the other essays. As you might guess, my answer to the title question is “No,” while many of the other entries will be arguing “Yes” (or at least be sympathetic to that view). I think of my job as less about changing minds than informing — I want thoughtful people who are committed Christians reading this volume to at least understand where I am coming from, even if they don’t agree. Think of it as an elaboration of “Why (Almost All) Cosmologists Are Atheists,” which was a bit breezier.

Hopefully there is still a bit of time for tweaking the essay before the editors get back to me with their comments, so please let me know if you think I’m getting something importantly wrong. Again, the whole thing is here, but I’m including the final section (minus the footnotes) as a teaser below the fold. In the earlier sections I do more nitty-gritty cosmological stuff, talking about the Big Bang, the anthropic principle, and meta-explanatory maneuvers. In this section I finally evaluate the God hypothesis in scientific terms. …

Modal Logic and the Ontological Proof

The ontological proof for the existence of God (really “proofs” or perhaps “arguments,” as there are various versions) has popped up in the blogs a few times recently: e.g. Ophelia Benson, Josh Rosenau, Jerry Coyne. You’ve probably heard this one; it was most famously formulated by Saint Anselm, and most famously trashed by Immanuel “Existence is not a predicate” Kant. A cartoon version of it would be something like

  1. God is by definition a perfect being.
  2. It is more perfect to exist than to not exist.
  3. Therefore, God exists.

Now, this is a really cartoonish version of the argument — it’s not meant to be taken seriously. This kind of ontological proof is a favorite whipping-argument for atheists, just because it seems so prima facie silly. Just ask Jesus and Mo.

This kind of mockery is a little unfair (although only a little). What’s important to realize is that the ontological proof is perfectly logical — that is, the conclusions follow inevitably from the premises. It’s the premises that are a bit loopy.

It’s instructive and fun to see this in terms of formal logic, especially because the proof requires modal logic — an extension of standard logic that classifies propositions not only as “true” or “false,” but also as “necessarily true/false” and “possibly true/false.” That is, it’s a logic of hypotheticals.

So here is one formalization of the ontological argument, taken from a very nice exposition by Peter Suber. First we have to define some notation to deal with our modalities. We denote possibility and necessity via:

Just given these simple ideas, a few axioms, and a fondness for pushing around abstract symbols, we’re ready to go. Remember that “~” means “not,” a “v” means “or,” and the sideways U means “implies.” Take “p” to be the proposition “something perfect exists,” and we’re off: …

Theologians Lobby Successfully to Change Definition of Evolution

If anyone wants an example of why some of us object strongly to the “accommodationist” strategy of downplaying the incompatibility of science and (many types of) religious belief, Jerry Coyne’s blog post will help you out. A bit too much, actually — the more you really think about it, the angrier it will make you feel. No wonder why these atheists are all so strident!

Apparently the National Association of Biology Teachers characterizes used to characterize the theory of evolution in the following way:

The diversity of life on earth is the result of evolution: an unsupervised, impersonal, unpredictable and natural process of temporal descent with genetic modification that is affected by natural selection, chance, historical contingencies and changing environments.

That’s a good description, because it’s true. But some religious thinkers, along with their enablers within the scientific establishment, objected to the parts about “unsupervised” and “impersonal,” because they seemed to exclude the possibility that the process was designed or guided by God. Which they do! Because that’s what the theory of evolution says, and that theory is far and away our best understanding of the data. (Dysteleological physicalism.)

The shocking part of the story is that the objectors won. The National Association of Biology Teachers officially changed their description of evolution, to better accommodate the views of theologians.

This isn’t a brand new story, but I had never heard it before. Jerry seems a lot more calm about it than I am, so you should read his post for more. I’ll just quote one short paragraph from him:

In my classes, however, I still characterize evolution and selection as processes lacking mind, purpose, or supervision. Why? Because, as far as we can see, that’s the truth.

The truth still matters.

A Sense of Doubt

Jerry Coyne, cheerful fire-breathing atheist that he is, gets invited to a church to talk about evolution. That’s not how it worked out, as people were more interested in talking about the relationship between science and religion. You can guess what happened — or maybe not. There was a productive two-hour conversation in which both sides learned something.

That’s pretty much the same thing that happened when I visited a Chicago church back in the day. There’s obviously a selection effect at work: the kinds of churches that invite atheists in for conversations are generally ones that enjoy some kind of open dialogue. Not that it’s all warm hugs and pleasant disagreement; I noticed that the older generation in my audience was a lot less open to even thinking about some of the points I raised, while Jerry had to fend off someone who thought that math and science had led to Nazi Germany.

Jerry concludes that the harmful aspects of religion are correlated with the certainty displayed by its adherents. This is a true but subtle point, as of course there are those who love to accuse scientists and/or atheists of unwarranted certitude. I think the difference is that we feel relatively sure about some things, while we’re quite ready to admit that we don’t know the answer to other questions, and we have a clear notion of where the distinction lies. But I would think that, wouldn’t I?

Conversations like these are enormously helpful. The trick is that it’s much easier — on both sides — to be polite and interactive in person, while the temptation to lecture people from on high is irresistible in other contexts, where it’s easier to think of the opposition as cartoons rather than real people.

Religion and Truth

One thing that religions typically do — although certainly not the only one — is to make claims about how the world works. How important are those claims to what religion really is, and how we should think about it?

PZ Myers has posted a very interesting letter from Stephen Asma that talks about this issue. Asma earlier wrote a critique of New Atheism in the Chronicle of Higher Education, to which PZ responded, but I think the new letter is more interesting than the previous salvos. Russell Blackford has also chimed in.

This is a very healthy discussion to be having — moving a bit beyond the caricatures of atheism by believers, and of religion by atheists. Much of what Asma says I find quite persuasive. The crux is something like this:

My argument is that religion helps people, rightly or wrongly, manage their emotional lives. And while it doesn’t do very much for me and other skeptics (I prefer art), I would be very inattentive if I failed to notice how much relief and comfort it gave to other people.

Asma wants to consider the aspects of religion that are closer to those of art or literature than those of science. There’s no question that religions have beneficial effects along with their bad ones. If we’re being rational about it, we should try to understand how those effects work, even if our only agenda is to find some sort of acceptable substitute.

If we were starting from scratch I would put it this way: some of the sense of wonder and anticipation of possibility that defines us as human is often categorized under the heading of “religion.” We can raise questions about the truthfulness of religion’s attempts to describe how the world works, while at the same time respecting some of the careful thought that religious people have put into understanding the human condition.

But … there’s usually a “but.” I have to wonder about these attempts to completely downplay the role of truth-claims in religious belief. In my experience, when I hear someone arguing that the important aspects of religion are moral or aesthetic, and the statements about how the world works are an unfortunate bit of historical baggage, it usually is not coming from a religious person, but rather from a sympathetic non-believer. My impression is that the way a religion views the world is actually quite important to a typical believer. I have in mind both very specific kinds of claims, that God created the world some number of years ago or that we are sorted into various afterlives depending on our Earthly track record, or more vague ones, that God allows the world to be or that moments of transcendence represent connection with a higher power. I don’t think these are unimportant to most religious believers, even most very sophisticated ones (I could be wrong).

And, needless to say, views about how the world works are very often central to the other aspects of religious belief. If you really believe in Heaven and Hell, you’d be crazy not to let that belief influence your view of morality here on Earth.

So, while I’m all in favor of understanding the nature of religious belief and also exhibiting a willingness to learn from believers who have thought long and hard about philosophy or ethics or what have you, I don’t foresee having a truly open and respectful dialogue without putting questions of how the world really works front and center. If we took a religion and removed from it any claims about how the world works, leaving a set of ideas about morality and human life, would it make sense to even call the result a religion? It would be more like a philosophy or worldview, and those are things that even we atheists are more than happy to engage with.

Still, we don’t always do a good job of that engagement. I look forward to the day when “atheism” as a worldview takes difficult emotional human questions more seriously in a public way.

Wicked Company

wickedcompany
Via 3 Quarks Daily, an Economist review of what looks like a fun book: Philipp Blom’s A Wicked Company: The Forgotten Radicalism of the European Enlightenment.

It is the story of the scandalous Paris salon run by Baron Paul Thierry d’Holbach, a philosophical playground for many of the greatest thinkers of the age. Its members included Denis Diderot (most famous as the editor of the original encyclopedia, but, Mr Blom argues, an important thinker in his own right), Jean-Jacques Rousseau, the father of romanticism, and the baron himself; even David Hume, a famous Scottish empiricist, paid the occasional visit.

I have a special fondness for these guys, having taught a course about them. As much as I am a forward-thinking person, the modern mode of expression by freethinkers (pounding out passionate diatribes on our keyboards) isn’t quite as much fun as gathering in a salon among good food and drink to denounce hypocrisy and spread the Enlightenment message.

Apparently Blom’s historical account has a contemporary message:

Even today, and even in secular western Europe, the bald and confident atheism and materialism of Diderot and Holbach seems mildly shocking. We still cling stubbornly to the idea of an animating soul, a spiritual ghost in the biological machine. For Mr Blom, the modern, supposedly secular world has merely dressed up the “perverse” morality of Christianity in new and better camouflaged ways. We still hate our bodies, he says, still venerate suffering and distrust pleasure.

This is the message of Mr Blom’s book, hinted at but left unstated until the closing chapters. He believes the Enlightenment is incomplete, betrayed by its self-appointed guardians. Despite all the scientific advances of the past two centuries, magical thinking and the cultural inheritance of Christianity remain endemic.

Sounds pretty darn accurate. Let’s order some bottles of wine and get this job finished!

Stephen Hawking Settles the God Question Once and For All

Stephen Hawking has a new book coming out (The Grand Design, with Leonard Mlodinow). Among other things, he points out that modern physics has progressed to the point where we don’t need to invoke God to explain the existence of the universe. This is not exactly a hot flash — I remember writing an essay making the same point for a philosophy class my sophomore year in college — but it makes news because it’s Hawking who says it. And that’s absolutely fine — Hawking has a track record of making substantial intellectual contributions, there’s every reason to listen to him more than random undergraduates waxing profound.

This issue is, of course, totally up my alley, and I should certainly blog about it. But I can’t, because I’m on hiatus! (Right?) So, as an experiment, I made a video of myself talking rather than simply typing my words into the computer. Radical! Not sure the amount of information conveyed is anywhere near as large in this format, and obviously I didn’t sweat the production values. I fear that some subtleties of the argument may be lost. But if we’re lucky, other people elsewhere on the internet will also talk about these questions, and we’ll get it all sorted out.

Let me know if the Grand Video Experiment is worth repeating and improving, or whether it’s just a waste of time.

Something that I should have said, but didn’t: there doesn’t need to be some sophisticated modern-physics answer to the question “Why is there something rather than nothing?” The universe can simply exist, end of story. But it’s still fun to think carefully about all the possibilities, existence and non-existence both included.

Reluctance to Let Go

There’s a movement afoot to frame science/religion discussions in such a way that those of who believe that the two are incompatible are labeled as extremists who can be safely excluded from grownup discussions about the issue. It’s somewhat insulting — to be told that people like you are incapable of conducting thoughtful, productive conversations with others — and certainly blatantly false as an empirical matter — I’ve both participated in and witnessed numerous such conversations that were extremely substantive and well-received. It’s also a bit worrisome, since whether a certain view is “true” or “false” seems to take a back seat to whether it is “moderate” or “extreme.” But people are welcome to engage or not with whatever views they choose.

What troubles me is how much our cultural conversation is being impoverished by a reluctance to face up to reality. In many ways the situation is parallel to the discussion about global climate change. In the real world, our climate is being affected in dramatic ways by things that human beings are doing. We really need to be talking about serious approaches to this problem; there are many factors to be taken into consideration, and the right course of action is far from obvious. Instead, it’s impossible to broach the subject in a public forum without being forced to deal with people who simply refuse to accept the data, and cling desperately to the idea that the Earth’s atmosphere isn’t getting any warmer, or it’s just sunspots, or warmth is a good thing, or whatever. Of course, the real questions are being addressed by some people; but in the public domain the discussion is blatantly distorted by the necessity of dealing with the deniers. As a result, the interested but non-expert public receives a wildly inaccurate impression of what the real issues are.

Over the last four hundred or so years, human beings have achieved something truly amazing: we understand the basic rules governing the operation of the world around us. Everything we see in our everyday lives is simply a combination of three particles — protons, neutrons, and electrons — interacting through three forces — gravity, electromagnetism, and the strong nuclear force. That is it; there are no other forms of matter needed to describe what we see, and no other forces that affect how they interact in any noticeable way. And we know what those interactions are, and how they work. Of course there are plenty of things we don’t know — there are additional elementary particles, dark matter and dark energy, mysteries of quantum gravity, and so on. But none of those is relevant to our everyday lives (unless you happen to be a professional physicist). As far as our immediate world is concerned, we know what the rules are. A staggeringly impressive accomplishment, that somehow remains uncommunicated to the overwhelming majority of educated human beings.

That doesn’t mean that all the interesting questions have been answered; quite the opposite. Knowing the particles and forces that make up our world is completely useless when it comes to curing cancer, buying a new car, or writing a sonnet. (Unless your sonnet is about the laws of physics.) But there’s no question that this knowledge has crucial implications for how we think about our lives. Astrology does not work; there is no such thing as telekinesis; quantum mechanics does not tell you that you can change reality just by thinking about it. There is no life after death; there’s no spiritual essence that can preserve a human consciousness outside its physical body. Life is a chemical reaction; there is no moment at conception or otherwise when a soul is implanted in a body. We evolved as a result of natural processes over the history of the Earth; there is no supernatural intelligence that created us and maintains an interest in our behavior. There is no Natural Law that specifies how human beings should live, including who they should marry. There is no strong conception of free will, in the sense that we are laws unto ourselves over and above the laws of nature. The world follows rules, and we are part of the world.

How great would it be if we could actually have serious, productive public conversations about the implications of these discoveries? For all that we have learned, there’s a tremendous amount yet to be figured out. We know the rules by which the world works, but there’s a lot we have yet to know about how to live within it; it’s the difference between knowing the rules of chess and playing like a grandmaster. What is “life,” anyway? What is consciousness? How should we define who is a human being, and who isn’t? How should we live together in a just and well-ordered society? What are appropriate limits of medicine and biological manipulation? How can we create meaning and purpose in a world where they aren’t handed to us from on high? How should we think about love and friendship, right and wrong, life and death?

These are real questions, hard questions, and we have the tools in front of us to have meaningful discussions about them. And, as with climate change, some people are having such discussions; but the public discourse is so badly distorted that it has little relationship to the real issues. Instead of taking the natural world seriously, we have discussions about “Faith.” We pretend that questions of meaning and purpose and value must be the domain of religion. We are saddled with bizarre, antiquated attitudes toward sex and love, which have terrible consequences for real human beings.

I understand the reluctance to let go of religion as the lens through which we view questions of meaning and morality. For thousands of years it was the best we could do; it provided social structures and a framework for thinking about our place in the world. But that framework turns out not to be right, and it’s time to move on.

Rather than opening our eyes and having the courage and clarity to accept the world as it is, and to tackle some of the real challenges it presents, as a society we insist on clinging to ideas that were once perfectly reasonable, but have long since outlived their usefulness. Nature obeys laws, we are part of nature, and our job is to understand our lives in the context of reality as it really is. Once that attitude goes from being “extremist” to being mainstream, we might start seeing some real progress.

The World Science (and Faith) Festival

I have to agree with Jerry Coyne here: the program on Faith and Science at this year’s World Science Festival is a mistake. I went to last year’s Festival, and I have great respect for Brian Greene and Tracy Day for bringing together such a massive undertaking. It would be better if they didn’t take money from the Templeton Foundation, but money has to come from somewhere, and I’m not the one paying the bills. I don’t even mind having a panel that talks about religion — it’s a big part of many people’s lives, and there are plenty of issues to be discussed at the intersection of science and religion.

But it would be a lot more intellectually respectable to present a balanced discussion of those issues, rather than the one that is actually lined up. The panelists include two scientists who are Templeton Prize winners — Francisco Ayala and Paul Davies — as well as two scholars of religion — Elaine Pagels and Thupten Jinpa. Nothing in principle wrong with any of those people, but there is a somewhat obvious omission of a certain viewpoint: those of us who think that science and religion are not compatible. And there are a lot of us! Also, we’re right. A panel like this does a true disservice to people who are curious about these questions and could benefit from a rigorous airing of the issues, rather than a whitewash where everyone mumbles pleasantly about how we should all just get along.

I’m not as much of an anti-Templeton fundamentalist as some people are; I won’t take money from them, but I will cooperate with institutions and organizations that do take money from them, even as I grumble about it. (Money laundering as the route to moral purity.) But this event is a perfect example of the ultimately pernicious influence that Templeton has. I disagree with Jerry and others who consider Templeton money a “bribe” to people who are willing to go along with their party line; I have no doubt that Ayala, Davies, Pagels and Jinpa will express only views that they sincerely hold and would still hold in the absence of any monetary reward. What Templeton does is that it hands people with those views a giant megaphone. Francisco Ayala is a respected scientist who happens to believe that science and religion complement each other rather than coming into conflict; that’s fine, although somewhat unremarkable. But then he wins the Templeton Prize, and that exact same opinion gets plastered all over the media.

Panels like this one at the WSF are the same story. Maybe exactly the same event would have been organized even if Templeton had nothing to do with the Festival; but I doubt it. (Update: upon reflection, I don’t know what the process was by which the event was organized, and I shouldn’t cast dark aspersions in the absence of evidence. My real point is that I don’t think that the panel should have happened the way it did, and I don’t want to detract from that.) Plenty of science festivals and museums seem to get along perfectly well without discussing religion at all. And if you did want to discuss it, there’s no way that an honest investigation into how scientists feel about religion would end up leaving out some fully committed atheists who would be pretty uncompromising towards belief.

Four hundred years after Galileo turned his telescope on the heavens, it’s incredibly frustrating that we still have debates over whether the world can be described in purely naturalistic terms, rather than accepting that insight as an amazing accomplishment and moving on to the hard work of articulating its consequences. It’s a shame that the World Science Festival is helping to keep us back, rather than moving us forward.

What to do about the Pope?

When it comes to religion, I’m more interested in scientific and philosophical questions — Does God exist? Can science say anything about the supernatural? — than in sociological or political ones — Is religion good and or evil?, etc. So there was not much temptation to wade in on Pope Benedict’s recent troubles, or the wider issue of sex scandals in the Catholic Church.

Now, happily, that temptation has dipped to zero, since Phil Plait has done such a good job. Read the whole thing, as they say. Roughly, Phil notes that the Pope seems to be responsible for some very bad things; that he should be brought to justice for any wrong-doings; that there is some relevance to concerns of the skeptical community, insofar as the Church invokes supernatural explanations; but finally, that the strategy should not be simply one of proclaiming superiority and tarring religion as evil and demanding heads on plates. Catholics and other believers, whether we disagree with them or not, are human beings who will understandably be upset and troubled at the recent news. We don’t help to convert them to atheism or naturalism or skepticism by shoving the shortcomings of their leaders in their faces in the midst of a crisis; reason and rational discourse should be more our style. It’s a nuanced argument, which means it’s guaranteed to be misunderstood and caricatured, since even God can’t control the natural impulses of the internet.

Let’s be clear: I want religion to vanish. I think that religious beliefs are wrong, and that the world would be a better place if everyone accepted the real world for what it is. And I believe that many of the actions of the Church when it comes to pedophilia certainly deserve the label “evil,” whatever one might think of the people who perpetrated them.

So the question is, how to bring about the rationalist utopia in which people’s actions are based on reason and reflection rather than faith and hierarchy? I agree with Phil’s answers, as I’ve argued in other contexts. One of the primary tenets of a rationalist philosophy should be that we should be especially skeptical about claims that we want to be true. Our personal preferences don’t have any effect on the truth, so we need to guard against confirmation bias and lazy acceptance of ideas that make us happy. One great example is the idea that we’re going to make the world a better and more rational place by telling everyone how much smarter we are than everyone else, and how evil and stupid our enemies are. The Pope’s recent actions, it seems clear, are some combination of evil and stupid. But now is just not the time for patting ourselves on the back. A lot of people have been deeply hurt, directly or indirectly, and we should be able to show just a modicum of restraint. Not giving up or keeping quiet, but picking our spots. After all, we don’t have to win by being obnoxious — we can win by being right.
