Carroll on laws and causation

People have been asking me to comment on the remarks about causation made by atheist physicist Sean Carroll during his recent debate with William Lane Craig on the topic of “God and Cosmology.”  (You’ll find Craig’s own post-debate remarks here.)  It’s only fair to acknowledge at the outset that Carroll cannot justly be accused of the anti-philosophical philistinism one finds in recent remarks by physicists Stephen Hawking, Lawrence Krauss, and Neil deGrasse Tyson.  Indeed, Carroll has recently criticized these fellow physicists pretty harshly, and made some useful remarks about the role of philosophy vis-à-vis physics in the course of doing so.

Churchland on dualism, Part V

Paul Churchland has just published a third edition of Matter and Consciousness, his widely used introductory textbook on the philosophy of mind.  The blog Philosophy of Brains has posted a symposium on the book, with contributions from Amy Kind, William Ramsey, and Pete Mandik.  Prof. Kind, who deals with Churchland’s discussion of dualism, is kind to him indeed -- a little too kind, as it happens.  Longtime readers will recall a series of posts I did several years ago on the previous edition of Churchland’s book, in which I showed how extremely superficial, misleading, and frankly incompetent is its treatment of dualism.  Prof. Kind commends Churchland’s “clear writing style and incisive argumentation” as “a model for us all.”  While I agree with her about the clarity of Churchland’s style, I cannot concur with her judgment of the quality of the book’s argumentation, for at least with respect to dualism, this new edition is as bad as the old. 

Links not to miss

I’ve been out of town for most of a week.  Regular blogging will resume shortly.  Until then, some reading material from around the web.

At the Telegraph, historian Tim Stanley has some advice for conservatives tempted to despair.

David Oderberg’s new article “Natural Law and Rights Theory” is available online.  (Follow the link from the Articles page at David’s website.) 

Sally Satel and Scott Lilienfeld’s Brainwashed: The Seductive Appeal of Mindless Neuroscience is discussed over at National Review.  But Slate wonders whether the age of neuro-hype is already over.

At The Catholic Thing, Brad Miner is critical of what some Catholic bishops have had to say about immigration.

Fifty shades of nothing

Note: The following article is cross-posted over at First Things.

Nothing is all the rage of late.  Physicists Stephen Hawking and Lawrence Krauss have devoted pop science bestsellers to trying to show how quantum mechanics explains how the universe could arise from nothing.  Their treatments were preceded by that of another physicist, Frank Close (whose book Nothing: A Very Short Introduction, should win a prize for Best Book Title). New Scientist magazine devoted a cover story to the subject not too long ago, and New Yorker contributor Jim Holt a further book.  At the more academic end of the discussion, the medieval philosophy scholar John F. Wippel has edited a fine collection of new essays on the theme of why anything, rather than nothing, exists at all.  And now John Leslie and Robert Lawrence Kuhn have published The Mystery of Existence: Why Is There Anything At All?, a very useful anthology of classic and contemporary readings.

Craig on theistic personalism

Someone posted the following clip at YouTube, in which William Lane Craig is asked about me and about his view of the dispute between classical theism and theistic personalism:

Schliesser on the Evolutionary Argument against Naturalism

I commented recently on the remarks about Thomas Nagel’s Mind and Cosmos made by Eric Schliesser over at the New APPS blog.  Schliesser has now posted an interesting set of objections to Alvin Plantinga’s “Evolutionary Argument against Naturalism” (EAAN), which features in Nagel’s book.  Schliesser’s latest comments illustrate, I think, how very far one must move away from what Wilfred Sellars called the “manifest image” in order to try to respond to the most powerful objections to naturalism -- and how the result threatens naturalism with incoherence (as it does with Alex Rosenberg’s more extreme position).

Nagel and his critics, Part II

Whereas my First Things review of Thomas Nagel’s Mind and Cosmos accentuated the positive, the first post in this series put forward some criticisms of the book.  Let’s turn now to the objections against Nagel raised by Brian Leiter and Michael Weisberg in their review in The Nation.  

First some stage setting is in order.  As I indicated in the previous post, Mind and Cosmos is mostly devoted to the positive task of spelling out what a non-materialist version of naturalism might look like.  The negative task of criticizing materialist forms of naturalism is carried out in only a relatively brief and sketchy way, and here Nagel is essentially relying on arguments he and others have developed at greater length elsewhere.  Especially relevant for present purposes is a line of argument Nagel put forward in what is perhaps his most famous piece of writing -- his widely reprinted 1974 article “What Is It Like to Be a Bat?” -- and developed further in later works like The View From Nowhere.

Cosmological argument roundup

A year ago today I put up a post with the title “So you think you understand the cosmological argument?”  It generated quite a bit of discussion, and has since gotten more page views than any other post in the history of this blog.  To celebrate its first anniversary -- and because the argument, rightly understood (as it usually isn’t), is the most important and compelling of arguments for classical theism -- I thought a roundup of various posts relevant to the subject might be in order.

Atheistic teleology?

There has been a lot of talk in the blogosphere and elsewhere about former atheist blogger Leah Libresco’s recent conversion to Catholicism.  It seems that among the reasons for her conversion is the conviction that the possibility of objective moral truth presupposes that there is teleology in the natural order, ends toward which things are naturally directed.  That there is such teleology is a thesis traditionally defended by Catholic philosophers, and this is evidently one of the things that attracted Libresco to Catholicism.  A reader calls my attention to this post by atheist philosopher and blogger Daniel Fincke.  Fincke takes issue with those among his fellow atheists willing to concede to Libresco that an atheist has to reject teleology.  Like Libresco, he would ground morality in teleology, but he denies that teleology requires a theological foundation.

Natural theology, natural science, and the philosophy of nature

Physicist Robert Oerter has added some further installments to his series of posts on my book The Last Superstition, including a reply to some of my criticisms of his criticisms of the book.  I will respond to his latest remarks in a forthcoming post, but before doing so it seemed to me that it would be useful to make some general remarks about certain misunderstandings that have not only cropped up in my exchange with Oerter and in the combox discussions it has generated, but which frequently arise in disputes about natural theology (and, for that matter, in disputes about natural law ethics and about the immateriality and immortality of the soul).  In particular, they tend to arise in disputes about what we might call classical natural theology -- natural theology grounded in philosophical premises deriving from the Aristotelian, Neo-Platonic, and/or Scholastic traditions.

Reading Rosenberg, Part X

And now we reach, at long last, the end of our detailed critical look at Alex Rosenberg’s The Atheist’s Guide to Reality.  In this final post I want to examine what Rosenberg has to say about a set of philosophical arguments he regards as “among the last serious challenges to scientism” (p. 228).  The arguments in question all entail that the realm of conscious experience -- what common sense says we know only “from inside” (p. 238), from a point of view “somewhere behind the eyes” (p. 222) -- cannot be accounted for in terms of neuroscience or physical science more generally.  In his treatment of these arguments, we get Rosenberg simultaneously at his best and at his worst.

Reading Rosenberg, Part IX

Our long critical look at Alex Rosenberg’s The Atheist’s Guide to Reality now brings us at last to that most radical of Rosenberg’s claims -- the thesis that neither our thoughts nor anything else has any meaning whatsoever.  To the reader unfamiliar with recent philosophy of mind I should emphasize that the claim is not merely that our thoughts, actions, and lives have no ultimate point or purpose, which is hardly a novel idea.  It is far more bizarre than that.  Consider the following two sequences of shapes: “cat” and “^\*:”  We would ordinarily say that the first has meaning -- it refers to animals of the feline sort -- while the latter is a meaningless set of marks.  And we would ordinarily say that while the meaning of a word like “cat” is conventional, the meaning of our thoughts about cats -- from which the meaning of the word in question derives -- is intrinsic or “built in” to the thought rather than conventional or derived.  What Rosenberg is saying is that in reality, both our thoughts about cats and the sequence of shapes “cat” are as utterly meaningless as the sequence of shapes “^\*:”  Neither “cat” nor any of our thoughts is any more about cats or about anything else than the sequence “^\*:” is about anything.  Meaning, “aboutness,” or intentionality (to use the technical philosophical term) is an illusion.  In fact, Rosenberg claims, “the brain does everything without thinking about anything at all.”

“Reason Rally”: Doubleplusgood newspeak for groupthink!

There is a view of life which conceives that where the crowd is, there also is the truth, and that in truth itself there is need of having the crowd on its side.  There is another view of life which conceives that wherever there is a crowd there is untruth, so that (to consider for a moment the extreme case), even if every individual, each for himself in private, were to be in possession of the truth, yet in case they were all to get together in a crowd -- a crowd to which any sort of decisive significance is attributed, a voting, noisy, audible crowd -- untruth would at once be in evidence.

For a “crowd” is the untruth.

Søren Kierkegaard, “That Individual”

One of the symptoms of groupthink is the members’ persistence in conveying to each other the cliché and oversimplified images of political enemies embodied in long-standing ideological stereotypes…

When a group of people who respect each other’s opinions arrive at a unanimous view, each member is likely to feel that the belief must be true.  This reliance on consensual validation tends to replace individual critical thinking and reality-testing.

Irving Janis, Groupthink: Psychological Studies of Policy Decisions and Fiascoes, Second edition

I have always hated mobs.  Thus I dislike mass demonstrations with their slogans and banners, marches and sit-ins, and all the rest of the obnoxious apparatus of modern protest.  Usually the cause is bad, and the participants are ignorant yahoos.  But I dislike such rallies even when the cause is good and the participants well-meaning.  They may sometimes be necessary, but they are always regrettable and to be avoided if possible.

Reading Rosenberg, Part VIII

And now, dear reader, our critical look at Alex Rosenberg’s The Atheist’s Guide to Reality brings us to the pseudoscience du jour.  Wittgenstein famously said that “in psychology there are experimental methods and conceptual confusion” (Philosophical Investigations, II, xiv, p. 232).  He might as well have been talking about contemporary neuroscience -- or, more precisely, about how neuroscience becomes distorted in the hands of those rich in empirical data but poor in philosophical understanding.  Every week seems to bring some new sensationalistic claim to the effect that neuroscience has “shown” this or that -- that free will is an illusion, or that mindreading is possible, or that consciousness plays no role in human action -- supported by arguments notable only for the crudeness of the fallacies they commit.  

Tyler Burge has given the label “neurobabble” to this modern intellectual pathology, and Raymond Tallis calls it “neurotrash,” born of “neuromania.”  I’ve had reason to comment on it in earlier posts (here and here) and an extreme manifestation of the disease is criticized in the last chapter of The Last Superstition.  M. R. Bennett and P. M. S. Hacker subject neurobabble to detailed and devastating criticism in their book Philosophical Foundations of Neuroscience, and Tallis does a bit of housecleaning of his own in Aping Mankind.  Neurobabble is a key ingredient in Rosenberg’s scientism.  Like so many other contemporary secularists, he has got the brain absolutely on the brain, and maintains that modern neuroscience vindicates some of his more outrageous metaphysical claims.  In particular, he thinks that so-called “blindsight” phenomena establish that consciousness is irrelevant to our actions, and that neuroscientist Benjamin Libet’s experiments cast doubt on free will.  (Jerry Coyne, in a recent article, has made similar claims about free will.  What I’ll say about Rosenberg applies to Coyne as well.)

Reading Rosenberg, Part VII

Pressing on through Alex Rosenberg’s The Atheist’s Guide to Reality, we come to Rosenberg’s treatment of morality.  Followed out consistently, Rosenberg says, scientism entails nihilism.  As Rosenberg is keen to emphasize, this is not the same as moral relativism or moral skepticism.  It is not the claim that moral truth is relative, or that it is real but unknowable.  Nor is it the claim that everything is morally permitted.  It is a far more radical and disturbing claim than any of these views.  Nihilism, as Rosenberg understands it, is the view that there is no such thing as being “morally permitted” or “morally prohibited” in the first place.  For there is, given Rosenberg’s scientism, no intrinsic value in the world of the sort that is necessary for morality to be intelligible.  Morality -- not just commonsense or traditional morality, not just religious morality, but all morality, morality as such, including any purported secular, liberal, permissive morality -- is therefore an illusion.  

Reading Rosenberg, Part VI

Let’s continue our detailed critical look at Alex Rosenberg’s The Atheist’s Guide to Reality.  In the previous installment, we took a detour to consider how some of Rosenberg’s problematic views in the philosophy of biology are developed more systematically in his book Darwinian Reductionism.  Here we return to the text of Atheist’s Guide and to the subject of religion, though we are not quite done considering what Rosenberg has to say about biological matters.  For he argues that Darwinism not only makes theism unnecessary (as he falsely assumes), but is positively incompatible with it: “You can’t have your Darwinian cake and eat theism too,” insists Rosenberg.  In particular, he thinks Darwinism is incompatible with the idea that God is omniscient.  How so?

Reading Rosenberg, Part V

In the previous installment of our look at Alex Rosenberg’s The Atheist’s Guide to Reality, we began to examine what Rosenberg has to say about biological phenomena.  This time I want to take a brief detour and consider some of what Rosenberg says about the subject in his book Darwinian Reductionism.  I noted that while Atheist’s Guide pushes a generally uncompromising eliminative materialist line, Rosenberg resists the “eliminativist” label where issues in the philosophy of biology are concerned, and presents his views in that field as reductionist.  Darwinian Reductionism (a more serious book than Atheist’s Guide, and of independent interest) explains why.

Reading Rosenberg, Part IV

Alex Rosenberg’s dubious use of physics was the focus of the previous installment of our look at his new book The Atheist’s Guide to Reality.  In this post we’ll look at his dubious biological claims.  “When physics disposed of purposes,” Rosenberg tells us, “it did so for biology as well.”  Now as I’ve noted before, in fact modern physics has not “disposed” of purposes at all, if what Rosenberg means by this is that physics has somehow established the metaphysical claim that the material world is devoid of objective teleological features.  All it has done is to make the purely methodological move of confining itself to non-teleological descriptions of the phenomena it studies.  This no more shows that teleology doesn’t exist than the fact that I am confining my comments in this post to Rosenberg’s work shows that no other philosophers exist.  Moreover, the non-teleological methodology of modern physics rules out irreducibly teleological explanations in biology only if you buy into Rosenberg’s “physics or bust” brand of scientism, which he has given us no good reason to do.

Reading Rosenberg, Part III

Continuing our look at Alex Rosenberg’s The Atheist’s Guide to Reality, we come to Rosenberg’s treatment of the question “Where did the big bang come from?”  As serious students of the cosmological argument for the existence of God are aware, most of its defenders historically (including key figures like Aristotle, Aquinas, and Leibniz) are not arguing for a temporal first cause of the world.  Their claim is not that God must have caused the world to begin (though some of them believe that He did, for independent reasons) but rather that He must continually be sustaining the world in existence, and would have to be doing so even if the universe had no beginning.  But there is a version of the cosmological argument that does argue for a temporal first cause of the world, namely the kalām cosmological argument.  Rosenberg does not explicitly address any specific version of either argument, but he is, in effect, trying to rebut them both.

Reading Rosenberg, Part II

We saw in part I of this series that Alex Rosenberg’s new book The Atheist’s Guide to Reality is less about atheism than it is about scientism, the view that science alone gives us knowledge of reality.  This is so in two respects.  First, Rosenberg’s atheism is just one implication among others of his scientism, and the aim of the book is to spell out what else follows from scientism, rather than to say much in defense of atheism.  Second, that it follows from his scientism is thus the only argument Rosenberg really gives for atheism.  Thus, most of what he has to say ultimately rests on his scientism.  If he has no good arguments for scientism, then he has no good arguments either for atheism or for most of the other, more bizarre, conclusions he defends in the book.

So, does Rosenberg have any good arguments for scientism?  He does not.  In fact, he has only one argument for it, and it is quite awful.
