Caught in the net

Some of the regular readers and commenters at this blog have started up a Classical Theism, Philosophy, and Religion discussion forum.  Check it out.

Philosopher Stephen Mumford brings his Arts Matters blog to an end with a post on why he is pro-science and anti-scientism.  Then he inaugurates his new blog at Philosophers Magazine with a post on a new and improved Cogito argument for the reality of causation.

Speaking of which: At Aeon, Mathias Frisch discusses the debate over causation and physics.

The Guardian asks: Is Richard Dawkins destroying his reputation?  And at Scientific American, John Horgan says that biologist Jerry Coyne’s new book “goes too far” in denouncing religion.

Pigliucci on metaphysics

At Scientia Salon, philosopher Massimo Pigliucci admits to “always having had a troubled relationship with metaphysics.”  He summarizes the reasons that have, over the course of his career, made it difficult for him to take the subject seriously.  Surprisingly -- given that Pigliucci is, his eschewal of metaphysics notwithstanding, a professional philosopher -- none of these reasons is any good.  Or rather, this is not surprising at all, since there simply are no good reasons for dismissing metaphysics -- and could not be, given that all purported reasons for doing so themselves invariably embody unexamined metaphysical assumptions.  Thus, as Gilson famously observed, does metaphysics always bury its undertakers.

Accept no imitations

Given that he’s just become a movie star, Alan Turing’s classic paper “Computing Machinery and Intelligence” seems an apt topic for a blog post.  It is in this paper that Turing sets out his famous “Imitation Game,” which has since come to be known as the Turing Test.  The basic idea is as follows: Suppose a human interrogator converses via a keyboard and monitor with two participants, one a human being and one a machine, each of whom is in a different room.  The interrogator’s job is to figure out which is which.  Could the machine be programmed in such a way that the interrogator could not determine from the conversation which is the human being and which the machine?  Turing proposed this as a useful stand-in for the question “Can machines think?”  And in his view, a “Yes” answer to the former question is as good as a “Yes” answer to the latter.

Summer web surfing

My Claremont Review of Books review of John Gray’s The Silence of Animals is now available for free online.

Keith Parsons has now wrapped up our exchange on atheism and morality at The Secular Outpost.

The latest from David Oderberg: “Could There Be a Superhuman Species?”  Details here.

Liberty Island is an online magazine devoted to conservatism and pop culture.  Music writer extraordinaire (and friend of this blog) Dan LeRoy is on board. 

James Franklin asks “What is mathematics about?”  (See also his new book An Aristotelian Realist Philosophy of Mathematics.)

What’s around the web?

John Searle is interviewed at New Philosopher.  He’s in fine Searle form (and well-armed, as you can see from the photo accompanying the interview):  “It upsets me when I read the nonsense written by my contemporaries, the theory of extended mind makes me want to throw up.”

Jeremy Shearmur is interviewed at 3:AM Magazine about his work on Karl Popper and F. A. Hayek.  Standpoint magazine on Hayek and religion.

A memorial conference for the late E. J. Lowe will be held this July at Durham University. 

Steely Dan is being sued by former member David Palmer.  GQ magazine looks back on Steely Dan’s Aja, and The Quietus celebrates and cerebrates the 40^th anniversary of Pretzel Logic.  Donald Fagen’s book Eminent Hipsters is reviewed in City Journal and in the New York Observer.

Some varieties of bullsh*t

Harry Frankfurt’s famous essay “On Bullshit” first appeared back in 1986 and was republished a few years ago in book form.  Though it has surely attracted too much attention from people who get an adolescent thrill out of the idea that they can do philosophy in a way that involves repeatedly saying the word “bullshit,” Frankfurt’s thesis is serious and important.  Bullshitting, Frankfurt argues, is not the same thing as lying.  The liar, like the truth-teller, cares about what is true.  The difference is that the truth-teller conveys it while the liar wants to cover it up.  The bullshitter, by contrast, doesn’t really care one way or the other about the truth.  He isn’t using his communicative faculties for the sake of conveying either truth or falsehood, but rather for some other end, such as promoting himself.

Man is Wolff to man

As a follow-up to my series of posts on the critics of Thomas Nagel’s Mind and Cosmos, let’s take a look at philosopher Robert Paul Wolff’s recent remarks about the book.  Wolff is not nasty, as some of the critics have been -- Nagel is Wolff’s “old friend and one-time student” -- but he is nevertheless as unfair to Nagel as some of them have been. 

Most of his post is not about Nagel at all, but consists of an anecdote about Edward O. Wilson and some remarks about the wealth of knowledge Wolff has found in the biology books he’s read.  The point is to illustrate how very meticulous good scientists can be, and how much they have discovered about the biological realm.  All well and good.  But so what?  What does that have to do with Nagel?

The return of final causality

I commend to you the late historian of philosophy Paul Hoffman’s paper “Does Efficient Causation Presuppose Final Causation?  Aquinas vs. Early Modern Mechanism.”  The paper appeared in the 2009 volume Metaphysics and the Good: Themes from the Philosophy of Robert Merrihew Adams, edited by Samuel Newlands and Larry Jorgensen, and I am pleased to find that it is available online.  It is part of a growing number of works by contemporary thinkers outside the Thomistic orbit which sympathetically reconsider or even defend (as Hoffman does) something like an Aristotelian conception of teleology.

Mad dogs and eliminativists

As an epilogue to my critique of Alex Rosenberg’s paper “Eliminativism without Tears,” let’s take a brief look at Rosenberg’s recent interview at 3:AM Magazine.  The interviewer styles Rosenberg “the mad dog naturalist.”  So perhaps in his bid to popularize eliminative materialism, Rosenberg could put out a “Weird Al” style parody of the old Noël Coward song.  Or maybe he and fellow eliminativist Paul Churchland could do a re-make of ZZ Top’s classic Eliminator album.  Don’t know if they’re sharp-dressed men, but they’ve got the beards.  (I can see the video now: The guys, electric guitars swaying in unison and perhaps assisted by Pat Churchland in a big 80s hairdo, set straight some benighted young grad student who still thinks the propositional attitudes are worth salvaging.  Romance ensues, as does a job at a Leiter-ranked philosophy department…)

Eliminativism without truth, Part III

Now comes the main event.  Having first set out some background ideas, and then looked at his positive arguments for eliminativism about intentionality, we turn at last to Alex Rosenberg’s attempt to defend his position from the charge of incoherence in his paper “Eliminativism without Tears.”  He offers three general lines of argument.  The first purports to show that a key version of the objection from incoherence begs the question.  The second purports to give an explanation of how what he characterizes as the “illusion” of intentionality arises.  The third purports to offer an intentionality-free characterization of information processing in the brain, in terms of which the eliminativist can state his position without implicitly appealing to the very intentionality-laden notions he rejects.  Let’s look at each argument in turn.

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.

Mind and Cosmos roundup

My series of posts on the critics of Thomas Nagel’s Mind and Cosmos has gotten a fair amount of attention.  Andrew Ferguson’s cover story on Nagel in The Weekly Standard, published when I was six posts into the series, kindly cited it as a “dazzling… tour de force rebutting Nagel’s critics.”  Now that the series is over it seems worthwhile gathering together the posts (along with some related materials) for easy future reference.

Mackie’s argument from queerness

In his book Ethics: Inventing Right and Wrong, J. L. Mackie famously put forward his “argument from queerness” against the objectivity of moral values.  The argument has both a metaphysical aspect and an epistemological aspect.  Mackie writes:

If there were objective values, then they would be entities or qualities or relations of a very strange sort, utterly different from anything else in the universe.  Correspondingly, if we were aware of them, it would have to be by some special faculty of moral perception or intuition, utterly different from our ordinary ways of knowing everything else. (p. 38)

Mackie’s claim is that we simply have no good reason to believe either in such odd entities as objective values or in an odd special faculty of moral knowledge.  We can explain everything that needs to be explained vis-à-vis morality by analyzing values in terms of our subjective responses to certain events in the world, and Ockham’s razor favors this approach to the alternative given the latter’s “queerness.”

Rosenhouse keeps digging

Here’s a conversation that might occur between grown-ups:

Grown-up #1: I haven’t read Nagel’s book or much of the positive commentary on it, but based on what I’ve seen in the popular press it all seems like a lot of absurd intellectual silliness based on caricature and sheer assertion.

Grown-up #2: Jeez, don’t you think you ought to read it before making such sweeping remarks?  You’re hardly going to get a good sense of the content of a set of complex philosophical arguments from a couple of journalistic pieces!

Grown-up #1: Yeah, I guess so.  Fair enough.

And here’s a conversation between a grown-up and Jason Rosenhouse:

The whole man

My recent review of Michael Gazzaniga’s Who’s in Charge? Free Will and the Science of the Brain is now available online at the Claremont Review of Books website.  And while you’re on the subject of philosophical anthropology, you might also take a look at William Carroll’s recent Public Discourse article “Who Am I? The Building of Bionic Man.”

Craig versus Rosenberg

Theist philosopher William Lane Craig debated atheist philosopher Alex Rosenberg at Purdue University on February 1.  You can watch the debate here.  I put forward my own detailed critique of Rosenberg’s book The Atheist’s Guide to Reality in a ten-part series of posts, of which you can find a roundup here.  As I’ve said before, one of Rosenberg’s strengths is that he is willing consistently to follow out the implications of scientism (however absurd and self-defeating, as we saw in the series of posts just referred to) in a way many other atheists do not.  Another is that, as this event indicates, he has (as a certain other prominent atheist famously appears not to have) the courage and intellectual honesty to debate the most formidable defenders of theism.

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.

Ray Bradbury (1920 - 2012)

When Ray Bradbury was twelve years old, he went to a carnival and encountered Mr. Electrico, a performer who sat in an electric chair with current running through him so that his hair stood up and an electrical sword he held would glow.  Touching the sword to the young Bradbury’s head, Mr. Electrico exclaimed: “Live forever!”  Alas, Mr. Electrico’s command has gone unheeded, for Bradbury died last Tuesday at 91 -- long-lived, to be sure, but well short of forever.

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.
