Readers’ comments on my free will piece—and my responses

January 3, 2012 • 6:59 am

The readers’ comments on my USA Today piece on free will did show the expected religious pushback, but not as much as I expected.  Before we get to them, I’ll deal with two other religious critics.

****

Predictably, at his own website the Thinking Christian says that the assumption of natural laws that absolutely determine our choices is an unjustified a priori conclusion, not supported by science itself. (Nope, it’s a conclusion based on experience.) The implicit view is that God interferes in these laws from time to time, and this may determine our “free will.” Oh, and I’m accused of denying free will because I’m pushing atheism:

Why would Coyne care to write about this, anyway? What’s the point, if we’re only “meat computers,” as he said later in the article?

I think he’s flogging (as the Brits would say it) naturalistic atheism here, under the guise of science. Elsewhere and frequently he has demonstrated a strong need to deny God. He is willing to give up humans to do so. For a being who cannot choose is not, as Aristotle described us, a rational animal. Such a being bears no resemblance to anything the ages and the sages have considered human.

At the end of his article he writes,

“. . . by losing free will we gain empathy, for we realize that in the end all of us, whether Bernie Madoffs or Nelson Mandelas, are victims of circumstance — of the genes we’re bequeathed and the environments we encounter. With that under our belts, we can go about building a kinder world.”

There are other, better ways to gain empathy. The Christian way of love and humility gains empathy without sacrificing humanness.

I’m not giving up humans: we exist, we have feelings, we interact with each other, and we act in the world, and those acts have effect. All I deny is that we can, at any moment, behave in any way different from what we did.

And yes, I do deny that there’s any evidence for God or contracausal choice.  If that makes me “sacrifice” humanness, then so be it.  I doubt that anyone who knows me would suggest that I am less than human or treat others that way.  And I deny free will—at least the contracausal form—on the basis of science, not atheism.

****

At First Things, run by Discovery Institute Fellow Wesley Smith, he has the usual response that denying free will means that “anything goes”:

The attack on free will is an attack on human exceptionalism, religion, and moral accountability–and a way of promoting and justifying relativism.  It is a means of allowing anything and judging nothing because whatever we do, it wasn’t essentially us doing it, anyway.  But somehow the I Robot peddler thinks we will be able to choose to use this information to build a better world! He ends:

“With that under our belts, we can go about building a kinder world.”

What?  We can take knowledge and apply it?  That contradicts Coyne’s entire thesis.

We see clearly here how determinism angers and upsets the religious. That much is predictable.  But Smith doesn’t seem to realize that words can affect actions.  And even though my words about free will were something I had no choice about writing, they can still affect peoples’ brains to help them have more empathy toward miscreants and people who are victims of circumstance.  OF COURSE we can apply knowledge in a deterministic world!

****

 

What I did find in the USA Today comments was resistance to the idea of contracausal free will, and this I fully expected.  From the answers, I remain convinced that many or most people are dualists—they really do believe in the ghost in the machine.  So before we begin inundating the average person with more “sophisticated” (i.e., compatibilist) notions of free will, shouldn’t we first convince them that their choice are predetermined by scientific laws?  For some reason some compatibilists aren’t too keen about doing that, perhaps become they sense that people will resist the “sophisticated” notions if they’re stripped of the kind of free will they want.  But it’s not our job to sugar-coat the pill by ignoring convenient and widespread fictions.  Our job is to tell the truth.

Here are some readers’ comments, with my brief responses below them.

This is religiously-based resistance, and the idea of dualism is implicit in boththe citation to Lewis and the obeisance to God as the source of morality, kindness, and mystery. And here we also see the reason for resistance: because free will (like the idea of evolution) appears to strip people of all meaning.  The similarity to religious arguments against evolution is striking!

And, by the way, did I ever claim that I said anything new? My article was trying simply to disseminate the idea that many (but not all!) philosophers and neuroscientists agree on

Two other points:  the fact that our thinking processes arose through evolution doesn’t make them faulty; our senses have evolved by and large (but not completely) to detect truth in the world, and our big brains have constructed the epiphenomenon of science to test the conclusions of our senses.  And we’re meaning-making organisms, too.  Natural selection has vouchsafed us brains that require love, that require activity, that require children, and seek pleasure and enjoyment. Those are all sources of meaning.  The only “meaning” we don’t have is the kind that requires a god.

What can I say about that? That’s similar to this comment:

LOL!

Enough.  One thing I didn’t expect was to be compared to Nazis and Communists, and I’m not sure what the official Party lines were about free will.  I suspect there weren’t any, but perhaps readers can enlighten me.

This is a common and erroneous objection to contracausal free will: why do anything if everything is determined? First, doing nothing at all—being nihilistic—is also pre-determined. And maybe whether you relapse or not is determined, but that doesn’t mean that you’re necessarily going to relapse.  The interventions of friends, or entry into drug programs, are environmental influences that can change one’s brain in a way that can reduce the possibility of relapse.  Of course whether you enroll in a program, or whether your friends help you, are also actions that are predetermined, but that doesn’t mean that our actions don’t have real consequences, and we should realize that. (See my response to Tom Clark below.)

Another fallacy: determinism means we can’t weigh things rationally because our judgments are “pre-wired.” That’s simply not true. Our prewiring is largely a rational one!

Our brains have evolved to weigh inputs in a way that produces the most adaptive output, and that usually (but not always) involves rational judgment.  If I see the tracks of a big felid on the savannah, and then hear rustling in the bushes nearby, I am going to be wary.  That’s determined, and it’s rational. If we want to eat berries, we avoid those that we know have made other people sick. Rational again.  If we want to persuade someone to do our bidding, we take into account the aspects of their personalities that are amenable to appeal.  We not only have brains that evolved to make “reasoned” judgments (though those judgments, or outputs, are determined completely by the inputs), and we are also organisms who learn, and learning often involves learning how to make rational choices.

This comment, which I hear often, is completely irrelevant to my claims. I don’t care whether the brain processes information the same way a computer does. (And, by the way, computers are capable of learning, too!).  What matters is not how the processing is done, but only whether, given a series of inputs, there will always be one predetermined output (absent any non-deterministic quantum effects). I predict that there will be, and I think most philosophers agree with me here.  They are, by and large, physical determinists, though they might also be compatibilists.

Well, what this person “believes” isn’t what I think is true. I “chose” to write the article only in the sense that I did it instead of anything else, and maintain that I couldn’t have done otherwise given my background: my genes and my environment. And yes, I think we are automatons of a sort.  If Mr. Miller thinks I could have chosen otherwise, let him adduce his best evidence and arguments. I can adduce my own arguments, which I claim are more persuasive, that I could not have done otherwise, and that my “choice” was the only choice I could have made. Therefore, in common parlance, it wasn’t a “choice” at all except that it is one of many things that I could have done in principle according to an outside observer.

I find this incoherent.  What is “limited” free will? A little ghost in the machine? Why would big things be determined or predestined and little ones not.  Still, I prefer this view to one claiming that nothing is predestined.

Mr. Clark has been a respected critic of my views on free will on this site and now at USA Today.  He is a determinist and a compatibilist. I agree with him on the former but not on the latter.  I haven’t read all of his many writings on the subject, but I have read many of them, and do think I understand his viewpoint, which is concisely expressed in the above. (I wish, though, that he’d have stated at the outset for the other readers that he agrees that all of our actions are predetermined by scientific laws. He does sort of imply that by saying “we ourselves are fully caused.”)

I guess in the end Tom and I simply differ in what we think of as “free will.”  I use the term (and I do define it) as the form of contracausal free will that I think most people intuitively accept: at any moment could I have made a different choice?  The answer is “no.”  In that sense, yes, I think it’s true that we “pretend” to make choices: we think that we can decide whether to get the soup or salad, but the laws of physics have decided the salad before I order.  Let me clarify further: I don’t maintain that all phenomena are analytically reducible to the laws of physics. Many have their own form of analysis, including Mendelian genetics, history, and archaeology.  I also agree that there are emergent properties that ultimately devolve to the laws of physics but are more profitably analyzed on a macro level (i.e., the behavior of crowds of humans at a football game).

I am still a bit puzzled by Mr. Clark’s stance. His assertion, for example, that “we retain our causal powers, even as we ourselves are fully caused,” confuses me.  If our actions ultimately devolve to physical laws, then what does it mean to say “we have causal powers”? Does it mean that our actions have consequences? If that’s so, then I fully agree. If I hit someone in the nose, he bleeds. All I claim is that those actions (the hitting and bleeding) are predetermined.  In the same way, the actions of a computer programmed to weld cars could be said to reflect that computer’s “retaining its causal powers” even though its program makes it “fully caused.” In what way, except in complexity, do we differ from such a computer?

And yes, the appearance of human choice making is real, but we have to admit that it’s an appearance alone: we could not have done otherwise.  It’s like consciousness, which is a real phenomenon in some sense, because we feel conscious. But it’s also illusory in the sense that there is no little “me” sitting in the brain, being aware and directing our activities.

Free will is the same kind of illusion. What is important to me is to show how science dispels the contracausal notion of free will (which I believe many if not most people still entertain), and to pass that along.  Clark has a different end, and I don’t fault him for using his own definition of free will..

In the end, Clark and I seem to agree largely on the principles and differ mostly in the semantics.  I define “free will” as I did above, and claim that that is how most people think of it.  And I think it’s part of the job of neuroscientists and psychologists to dispel that notion of free will.

How do Clark and I differ?  He defines free will, I think, as the non-coerced actions of people, actions that have real effects on the world and that “cause” things.  (If I’m wrong about this, I ask him to clarify below.)  That’s fine with me; if that’s his definition of free will, then yes, that definition is compatible with determinism.  My concern has been only to deal with the notion of contracausal free will, and to say why compatibilist stances, while palatable to philosophers, may not be palatable to the general public, many of whom desperately need (often for religious reasons) to believe in dualism. So it comes down to a semantic problem, I guess.  The important issue for me is determinism of “choices”, and I guess most of us agree on that.

Finally, I think I did make the point in my article that we shouldn’t confuse determinism with fatalism, so I can’t be faulted for that.

Winners: National Geographic photo contest

January 2, 2012 • 1:34 pm

Via The Atlantic we have the winners, honorable mentions, and just plain great pictures from the annual National Geographic photo contest. There were so many great ones that I couldn’t limit myself to just one or two, so I’m highlighting fifteen.  Captions are from The Atlantic.

As always, click to enlarge:

“Splashing”, Grand Prize Winner and winner of the Nature category. This photo was taken when I was taking photos of other insects, as I normally did during macro photo hunting. I wasn’t actually aware of this dragonfly since I was occupied with other objects. When I was about to take a picture of it, it suddenly rained, but the lighting was just superb. I decided to take the shot regardless of the rain. The result caused me to be overjoyed, and I hope it pleases viewers. Location: Batam, Riau Islands, Indonesia. (© Shikhei Goh)

“Sulfuric Fire Festival”, honorable mention in Places category. Once a year, Formosa fishermen’s unique sulfuric fire fishing ritual is handed down from generation to generation. Location: Taipei (© Hung-Hsiu Shih)

An unexpected side-effect of the 2010 flooding in parts of Sindh, Pakistan, was that millions of spiders climbed up into the trees to escape the rising flood waters; because of the scale of the flooding and the fact that the water took so long to recede, many trees became cocooned in spiders webs. People in the area had never seen this phenomenon before, but they also reported that there were less mosquitos than they would have expected, given the amount of standing water that was left. Not being bitten by mosquitoes was one small blessing for people that had lost everything in the floods. (© Russell Watkins)

My second favorite:

“The Hunt”, honorable mention in Nature category. I personally believe that, beyond the formal representation of reality, mediated by the technical instruments necessary to fix an image in time, photography is made of insights. The shot is the last act of image capturing and in many ways the easiest part of the whole process. This panning effect, even in its imperfection, with the chromatic harmony of the background, with all the needless information eliminated and the luck of having the big cat’s lifted tail in symmetry with the impala horns, brings the observer inside the hunting without distractions. Location: Kenya, Masai Mara National Reserve(© Stefano Pesarelli)

“Waterway to Orbit”, honorable mention in Places category. Space shuttle Endeavour STS-130 launches into orbit toward the east, as the stars and waning crescent moon trail toward the west, leaving a beautiful reflection on the Intracoastal Waterway in Ponte Vedra, Florida.

Tickling a penguin

January 2, 2012 • 9:38 am

Penguins, like kittehs, like tummy rubs.  If you don’t get a frisson of pleasure from this video, you’re at the wrong website. It’s Cookie, a baby fairy penguin (Eudyptula minor) at the Cincinnati Zoo, who is being treated for a foot ailment (note the “sock” on her foot).

On free will: my new piece in USA Today

January 2, 2012 • 5:31 am

I’ve written an op-ed piece that is online at the latest USA Today: “Why you don’t really have free will.

My views won’t surprise regular readers, many of whom of course object to such views.  To these detractors I’ll respond as did Hitchens at 7:03 (but, since I love my readers, without the invitation to posterior osculation): “I can’t find a seconder usually when I propose this but I don’t care. I don’t need a seconder. My own opinion is enough for me. And I claim the right to have it defended against any consensus, any majority, anywhere, any place, anytime.”

Actually, I do have a seconder:  Sam Harris, whose new book Free Will is due out out in March. His views are largely confluent with mine.

I’m sure I’ll hear from the usual defenders of compatibilism: the idea that physical determinism, on which I think most of us agree, is perfectly compatible with free will. And my feeling about compatibilism is pretty much the same as Sam’s, which he expresses in his upcoming book (quoted with permission):

As I have said, I think compatibilists like Dennett change the subject: They trade a psychological fact—the subjective experience of being a conscious agent—for a conceptual understanding of ourselves as persons. This is a bait and switch. The psychological truth is that people feel identical to a certain channel of information in their conscious minds. Dennett is simply asserting that we are more than this—we are coterminous with everything that goes on inside our bodies, whether we are conscious of it or not. This is like saying we are made of stardust—which we are. But we don’t feel like stardust. And the knowledge that we are stardust is not driving our moral intuitions or our system of criminal justice.

Compatibilists resemble theologians in many ways, not the least of which is that they both engage in endless lucubrations trying to show that something that doesn’t exist, but that is hugely important for our psychological well-being, really does exist in some form or another.  People hate the idea that they aren’t agents who can make free choices, just as they hate they idea that there might not be a Protective Father in heaven.

Some sophisticated philosophers who defend compatibilism also resemble sophisticated theologians: their language is fancy, but the content remains thin.  There’s another resemblance, too: as science (in this case neuroscience) does away with the traditional notion of free will, just as science did away with the traditional arguments for a Great Designer, philosophers simply make a philosophical virtue out of scientific necessity.  That’s precisely what theologians do with the God problem.

In the end, we simply aren’t agents who can make free choices among alternative courses of action. What we do is determined not by our own agency, but by physical laws. All else is rationalization.

I predict, because I claimed that dispensing with free will makes hash of many religious views, that the most flak I’ll get for this piece will not be from philosophers, academics, or smart secularists, but from the faithful.

Finally, I’ll quote Sam again from a piece he wrote earlier this year at PuffHo,:

The problem with compatibilism, as I see it, is that it tends to ignore that people’s moral intuitions are driven by a deeper, metaphysical notion of free will. That is, the free will that people presume for themselves and readily attribute to others (whether or not this freedom is, in Dennett’s sense, “worth wanting”) is a freedom that slips the influence of impersonal, background causes. The moment you show that such causes are effective–as any detailed account of the neurophysiology of human thought and behavior would– proponents of free will can no longer locate a plausible hook upon which to hang their notions of moral responsibility. The neuroscientists Joshua Greene and Jonathan Cohen make this same point:

Most people’s view of the mind is implicitly dualist and libertarian and not materialist and compatibilist . . . [I]ntuitive free will is libertarian, not compatibilist. That is, it requires the rejection of determinism and an implicit commitment to some kind of magical mental causation . . . contrary to legal and philosophical orthodoxy, determinism really does threaten free will and responsibility as we intuitively understand them (Greene J & J. Cohen. 2004).

Michael Ruse channels Walt Whitman

January 1, 2012 • 1:47 pm

Remember these lines from “Song of Myself,” one of Whitman’s poems in Leaves of Grass?

Do I contradict myself?
Very well then I contradict myself,
(I am large, I contain multitudes.)

That solipsistic verse always reminds me of the “some-scientists-are-religious” argument for accommodationism, but now it also reminds me of Michael Ruse.  Yes, he is large, and yes, he contains multitudes.  And this week he contradicts himself in a spectacularly muddled piece at the Chronicle of Higher Education, “The nature of morality: replies to critics“. In it, he defends his assertion that there is an objective morality that has been bred into us by natural selection, buttressing in turn his argument that there are “ways of knowing” that don’t come from science. (In this case the “way of knowing” is that there are objective moral truths vouchsafed us by natural selection. You can read his original argument here.)  This was part of a larger attack on scientism.

I don’t want to go into detail about the piece; if you want to wade through the marsh of his logic, such as it is, be my guest.  I just want to point out two contradictions.  But first the amusing and requisite dismissing of New Atheists and yours truly:

Well, I thought the Mormons were touchy, but they can’t hold a candle to the New Atheists, who are all over me for my views on the limits of science and, more particularly, the evolutionary-based nature of morality.  .  .

Here, lest I be accused of ignoring criticism, let me reply to three objections that have been leveled. The person these days who seems to find my thinking most offensively incorrect is the Chicago biologist Jerry Coyne. It is a strange world when my biggest critic is not some evangelical Young Earther, but the head of America’s major evolution society. [JAC: it’s a strange world when one of the people who defends religion most ardently is not one of the faithful, but an avowed atheist.] Half joking, I suggested that I should be grateful for the publicity and put him on my payroll. He in turn suggests that a payment of 50 bucks would be appropriate and I have just written and sent a check—although if he goes on claiming that Alvin Plantinga has a “liberal faith,” I shall want my money back.

I haven’t gotten the damn check yet, but I’ll entertain readers’ suggestions about how to spend the dough.

And now the contradictions:

  • First, the complaint that since I think morality is a product of evolution through natural selection, I must therefore be using science to justify my ethical claims. I too am committing the naturalistic fallacy. Not so. Distinguish between an explanation of the origin of something and its justification.

But later on he says:

My position is that evolutionary biology lays on us certain absolutes. These are adaptations brought on by natural selection to make us functioning social beings. It is in this sense that I claim that morality is not subjective.

Does anyone sense a contradiction there? Or can the philosophers among us use some casuistry to show that there’s a difference between saying that evolution doesn’t give us moral absolutes and that evolution does give us moral absolutes? That sounds like a job for Plantinga (aka Superman).

  • Contradiction two; Ruse says:

I fully expect that societies that have different views from ours about the nature of women and gays and whatever will have different moral codes about women and gays and whatever. It is not the morality itself that is different.

He uses the example of abortion here: some people differ on whether a fetus counts as a human being.  But that is a difference in morality, and anti-abortion activists are not going to abandon their views if you tell them that the three-month-old fetus isn’t human.  Telling them that a fetus that young isn’t conscious, for instance, or can’t survive outside the womb, isn’t going to make them suddenly think, “Whoa; I didn’t know that. I’m pro-choice now!”

I defy you to read that column and not think that Ruse is either philosophically muddled or simply phoned in the piece without thinking about it. Whatever the truth, he owes me another fifty bucks.

Lying for Jesus: Humans lived with dinosaurs

January 1, 2012 • 12:38 pm

If people ever say we’re exaggerating the ravages of creationism in the United States, have a look at this video. Check out the title in the subject line. The answer, of course, is a resounding, “YES! Praise Jesus!”

Non-American readers: be prepared to be gobsmacked by the stupidity here.

Eric Hovind and Paul Taylor are your hosts at this 30-minute episode on the Creation Today show. For most of the show Hovind is lecturing to kids.  I can’t think of anything more vile than promulgating such lies to children.

Hovind comes off, I must say, as a bit unhinged: as an amalgam of Jimmy Swaggart and Soupy Sales.

[vodpod id=ExternalVideo.1009484&w=425&h=350&fv=]

Among the highlights:

  • 4:02: Hovind claims to prove that dinosaurs are mentioned in the Bible (as “dragons”) and concludes without doubt that those dragons were really dinosaurs. (He later says that dragons are mentioned 35 times in the Bible, and Hovind determined that at least 23 of those refer to real dragons.)
  • 5:00: Hovind claims that the dinosaurs faced a “very hostile environment” after the Flood. But how did they survive it? He doesn’t mention that they were on the Ark.  And the dinos went extinct because of the debilitating post-flood climate.  How do we know? Because the human lifespan dropped from over 900 years before the flood (Methuselah) to 400, then 200, then 100.
  • 7:42: People also helped bring about the extinction of dinosaurs: they were killed for meat, to protect the kids, and even for medicinal purposes (ancient remedies called for “dragon blood”).
  • 10:45.  The Bible refers to dragons and serpents breathing fire.  Since the Bible is literally true, Hovind has to show that dinos could do that.  But of course they couldn’t. What does he do: had adduces “animals alive to day with those kinds of capabilities.” He’s apparently referring to bombadier beetle.  How that proves that reptiles breathed fire is beyond me.
  • More proof: the walls of Babylon had dragons engraved on them.  And of course there are the stories of Beowulf and Grendel, and St. George and the dragon. More evidence!
  • The Grand Canyon has Native American carvings of dragons!
  • 17:13: Hovind asserts that “behemoth” mention in the Book of Job was “obviously” a dinosaur
  • 20:25: Satan twisted God’s creation by making scientists say that dinosaurs really lived million years ago
  • 22:25:  Hovind offers the kids a choice between evolution (obviously disproven) and a creator.
  • 23:20:  Hovind tells the kids that evolutionists are deceiving people about the evidence we have to support our theory. (I’m checking myself for horns).

Of all the horrible aspects of religion, the worst is the imperative to brainwash kids with lies that support your own faith.
