Parfit on brute facts

Derek Parfit’s article “The Puzzle of Reality: Why Does the Universe Exist?” has been reprinted several times since it first appeared in the Times Literary Supplement in 1992, and for good reason.  It’s an admirably clear and comprehensive survey of the various answers that have been given to that question, and of the problems facing some of them.  (Unsurprisingly, I think Parfit’s treatment of theism, though not unfair, is nevertheless superficial.  But to be fair to Parfit, the article is only meant to be a survey.)

Christians, Muslims, and the reference of “God”

The question of whether Christians and Muslims worship the same God has become the topic du jour in certain parts of the blogosphere.  Our friends Frank Beckwith, Bill Vallicella, Lydia McGrew, Fr. Al Kimel, and Dale Tuggy are among those who have commented.  (Dale has also posted a useful roundup of articles on the controversy.)  Frank, Fr. Kimel, and Dale are among the many commentators who have answered in the affirmative.  Lydia answers in the negative.  While not firmly answering in the negative, Bill argues that the question isn’t as easy to settle as the yea-sayers suppose, as does Peter Leithart at First Things.  However, with one qualification, I would say that the yea-sayers are right.

Papal fallibility (Updated)

Catholic doctrine on the teaching authority of the pope is pretty clear, but lots of people badly misunderstand it.  A non-Catholic friend of mine recently asked me whether the pope could in theory reverse the Church’s teaching about homosexuality.  Said my friend: “He could just make an ex cathedra declaration to that effect, couldn’t he?”  Well, no, he couldn’t.  That is simply not at all how it works.  Some people think that Catholic teaching is that a pope is infallible not only when making ex cathedra declarations, but in everything he does and says.  That is also simply not the case.  Catholic doctrine allows that popes can make grave mistakes, even mistakes that touch on doctrinal matters in certain ways.

Poverty no, inequality si

Philosopher Harry Frankfurt is famous for his expertise in detecting bullshit.  In a new book he sniffs out an especially noxious instance of the stuff: the idea that there is something immoral about economic inequality per se.  He summarizes some key points in an excerpt at Bloomberg View  and an op-ed at Forbes.

Fulford on sola scriptura, Part II

Let’s return to Andrew Fulford’s reply at The Calvinist International to my recent post on Feyerabend, empiricism, and sola scriptura.  Recall that the early Jesuit critique of sola scriptura cited by Feyerabend maintains that (a) scripture alone can never tell you what counts as scripture, (b) scripture alone cannot tell you how to interpret scripture, and (c) scripture alone cannot give us a procedure for deriving consequences from scripture, applying it to new circumstances, etc.  In an earlier post I addressed Fulford’s reply to point (a).  Let’s now consider his attempt to rebut the other two points.

Feyerabend on empiricism and sola scriptura

In his essay “Classical Empiricism,” available in Problems of Empiricism: Philosophical Papers, Volume 2, philosopher of science Paul Feyerabend compares the empiricism of the early moderns to the Protestant doctrine of sola scriptura.  He suggests that there are important parallels between them; in particular, he finds them both incoherent, and for the same reasons.  (No, Feyerabend is not doing Catholic apologetics.  He’s critiquing empiricism.)

Causality and radioactive decay

At the Catholic blog Vox Nova, mathematics professor David Cruz-Uribe writes:

I… am currently working through the metaphysics of St. Thomas Aquinas as part of his proofs of the existence of God… [S]ome possibly naive counter-examples from quantum mechanics come to mind.  For instance, discussing the principle that nothing can change without being affected externally, I immediately thought of the spontaneous decay of atoms and even of particles (e.g., so-called proton decay).

This might be a very naive question: my knowledge of quantum mechanics is rusty and probably out of date, and I know much, much less about scholastic metaphysics.  So can any of our readers point me to some useful references on this specific topic? 

Meta-comedy

While we’re on the subject of Steve Martin, consider the following passage from his memoir Born Standing Up.  Martin recounts the insight that played a key role in his novel approach to doing stand-up comedy:

In a college psychology class, I had read a treatise on comedy explaining that a laugh was formed when the storyteller created tension, then, with the punch line, released it... With conventional joke telling, there's a moment when the comedian delivers the punch line, and the audience knows it's the punch line, and their response ranges from polite to uproarious.  What bothered me about this formula was the nature of the laugh it inspired, a vocal acknowledgment that a joke had been told, like automatic applause at the end of a song...

Olson contra classical theism

A reader asks me to comment on this blog post by Baptist theologian Prof. Roger Olson, which pits what Olson calls “intuitive” theology against “Scholastic” theology in general and classical theism in particular, with its key notions of divine simplicity, immutability, and impassibility.  Though one cannot expect more rigor from a blog post than the genre allows, Olson has presumably at least summarized what he takes to be the main considerations against classical theism.  And with all due respect to the professor, these considerations are about as weak as you’d expect an appeal to intuition to be.

Science dorks

Suppose you’re trying to teach basic arithmetic to someone who has gotten it into his head that the whole subject is “unscientific,” on the grounds that it is non-empirical.  With apologies to the famous Mr. Parker (pictured at left), let’s call him “Peter.”  Peter’s obviously not too bright, but he thinks he is very bright since he has internet access and skims a lot of Wikipedia articles about science.  Indeed, he proudly calls himself a “science dork.”  Patiently, albeit through gritted teeth, you try to get him to see that two and two really do make four.  Imagine it goes like this:

You’re not who you think you are

If I’m not me, who the hell am I?

Douglas Quaid (Arnold Schwarzenegger) in Total Recall

If you know the work of Philip K. Dick, then you know that one of its major themes is the relationship between memory and personal identity.  That is evident in many of the Dick stories made into movies, such as Do Androids Dream of Electric Sheep? (which was adapted into Blade Runner, definitely the best of the Dick film adaptations); “Paycheck” (the inferior movie adaptation of which I blogged about recently); and A Scanner Darkly (the movie version of which is pretty good -- and which I’ve been meaning to blog about forever, though I won’t be doing so here). 

Then there are the short stories “We Can Remember It for You Wholesale” (the first part of which formed the basis of the original Total Recall and its pointless remake), and “Impostor” (the basis of a middling Gary Sinise movie).  These two stories nicely illustrate what is wrong with the “continuity of consciousness” philosophical theories of personal identity that trace to John Locke.  (Those who don’t already know these stories or movies should be warned that major spoilers follow.)

Present perfect

Dale Tuggy has replied to my remarks about his criticism of the classical theist position that God is not merely “a being” alongside other beings but rather Being Itself.   Dale had alleged that “this is not a Christian view of God” and even amounts to “a kind of atheism.”  In response I pointed out that in fact this conception of God is, historically, the majority position among theistic philosophers in general and Christian philosophers in particular.  Dale replies:

Three comments. First, some of [Feser’s] examples are ambiguous cases. Perfect Being theology goes back to Plato, and some, while repeating Platonic standards about God being “beyond being” and so on, seem to think of God as a great self. No surprise there, of course, in the case of Bible readers. What’s interesting is how they held – or thought they held – these beliefs consistently together. Second, who cares who’s in the majority? Truth, I’m sure he’ll agree, is what matters. Third, it is telling that Feser starts with Plato and ends with Scotus and “a gazillion” Scholastics. Conspicuous by their absence are most of the Greats from early modern philosophy. Convenient, because most of them hold, with Descartes, that our concept of God is the “…idea of a Being who is omniscient, omnipotent and absolutely perfect… which is absolutely necessary and eternal.” (Principles of Philosophy 14)

Nietzschean natural law?

Some years ago, at an initially friendly dinner after a conference, I sat next to a fellow Catholic academic, to whom I mildly expressed the opinion that it had been a mistake for Catholic theologians to move away from the arguments of natural theology that had been so vigorously championed by Neo-Scholastic writers.  He responded in something like a paroxysm of fury, sputtering bromides of the sort familiar from personalist and nouvelle theologie criticisms of Neo-Scholasticism.  Taken aback by this sudden change in the tone of our conversation, I tried to reassure him that I was not denying that the approaches he preferred had their place, and reminded him that belief in the philosophical demonstrability of God’s existence was, after all, just part of Catholic doctrine.  But it was no use.  Nothing I said in response could mollify him.  It was like he’d seen a ghost he thought had been exorcised long ago, and couldn’t pull out of the subsequent panic attack.

Do machines compute functions?

Robert Oerter has now replied to my most recent post about his criticisms of James Ross’s argument for the immateriality of the intellect.  Let me begin my rejoinder with a parable.  Suppose you presented someone with the argument: All men are mortal; Socrates is a man; therefore, Socrates is mortal.  He says he is unconvinced.  Puzzled, you ask him why.  He replies that he is surprised that you think Socrates is mortal, given that you believe in the immortality of the soul.  He adds that all you’ve done in any case is to make an epistemological point about what we know about Socrates, and not really given any reason to think that Socrates is mortal.  For though the conclusion does, he concedes, follow from the premises, and the premises are supported by the evidence, maybe for all we know there is still somehow more to men than what the premises tell us.

Why Is There Anything At All? It’s Simple

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

I thank John Leslie and Robert Lawrence Kuhn for their gracious and substantive response to my recent comments on their fine anthology The Mystery of Existence: Why Is There Anything At All?  In the course of my earlier remarks, I put forward a “friendly criticism” to the effect that John and Robert had paid insufficient attention in their book to the tradition of classical theism, which has its philosophical roots in Aristotelian and Neo-Platonic thought and whose many illustrious representatives include Augustine, Anselm, Avicenna, Maimonides, and Aquinas.  Though there are selections from some of these writers, they are very brief, and the bulk of the theological selections in the book are from recent writers of what has sometimes been called a “theistic personalist” or “neo-theist” bent.  John and Robert have offered a lively defense of their approach.  In what follows I’d like to respond, pressing the case for the primacy of the classical theistic tradition.

Eliminativism without truth, Part II

We’re looking at Alex Rosenberg’s attempt to defend eliminative materialism from the charge of incoherence in his paper “Eliminativism without Tears.”  Having set out some background ideas in an earlier post, let’s turn to the essay itself.  It has four main parts: two devoted to arguments for eliminativism, and two devoted to responses to the charge of incoherence.  I’ll consider each in turn.

Eliminativism without truth, Part I

Suppose you hold that a good scientific explanation should make no reference to teleology, final causality, purpose, directedness-toward-an-end, or the like as an inherent and irreducible feature of the natural order.  And suppose you hold that what is real is only what science tells us is real.  Then you are at least implicitly committed to denying that even human purposes or ends are real, and also to denying that the intentionality of thought and the semantic content of speech and writing are real.  Scientism, in short, entails a radical eliminativism.  Alex Rosenberg and I agree on that much -- he defends this thesis in The Atheist’s Guide to Reality and I defend it in The Last Superstition.  Where we differ is over the lesson to be drawn from this thesis.  Rosenberg holds that scientism is true, so that eliminativism must be true as well.  I maintain that eliminativism is incoherent, and constitutes a reductio ad absurdum of the scientism that leads to it.  I responded to Rosenberg at length in a series of posts on his book.

In his paper “Eliminativism without Tears,” Rosenberg attempts in a more systematic way than he has elsewhere to respond to the charge of incoherence.  Rosenberg kindly sent me this paper some time ago, and I note that it is now available online.

A Christian Hart, a Humean head

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

In a piece in the March issue of First Things, David Bentley Hart suggests that the arguments of natural law theorists are bound to be ineffectual in the public square.  The reason is that such arguments mistakenly presuppose that there is sufficient conceptual common ground between natural law theorists and their opponents for fruitful moral debate to be possible.  In particular, they presuppose that “the moral meaning of nature should be perfectly evident to any properly reasoning mind, regardless of religious belief or cultural formation.”  In fact, Hart claims, there is no such common ground, insofar as “our concept of nature, in any age, is entirely dependent upon supernatural (or at least metaphysical) convictions.”  For Hart, it is only when we look at nature from a very specific religious and cultural perspective that we will see it the way natural law theorists need us to see it in order for their arguments to be compelling.  And since such a perspective on nature “must be received as an apocalyptic interruption of our ordinary explanations,” as a deliverance of special divine revelation rather than secular reason, it is inevitably one that not all parties to public debate are going to share.

Whose nature? Which law?

You’ve got your natural law.  You’ve got your natural rights.  You’ve got the state of nature.  Then there’s naturalism.  And laws of nature.  And the supernatural.  There’s St. Paul’s natural man and the Scholastics’ natura pura.  There’s nature and nature’s God.  There’s natural science, natural history, natural selection, natural theology, natural philosophy, and the philosophy of nature.  There’s the Baconian scientist putting nature on the rack, and Galileo telling us that the book of nature is written in the language of mathematics.  And let’s not forget the literal books, like Lucretius’s On the Nature of Things, Hume’s Treatise of Human Nature, Richard Rorty’s Philosophy and the Mirror of Nature, and Edward O. Wilson’s On Human Nature.  There’s Emerson’s essay “Nature.”  For fans of underground comics, there’s Mr. Natural; for fans of obscure superheroes too preposterous ever to get their own billion-dollar-grossing film adaptations, there’s Nature Boy.  There’s Oliver Stone’s movie Natural Born Killers and Robert Redford in The Natural.   There’s Ringo Starr singing “Act Naturally,”  Aretha Franklin’s “(You Make Me Feel Like) A Natural Woman,” the Steely Dan album Two Against Nature, and that stupid Gilbert O’Sullivan tune.  

There are natural disasters, natural resources, natural gas, and dying of natural causes.  There’s natural beauty, but also freaks of nature.  There’s going back to nature and getting a natural high.  There are Mother Nature, nature hikes, all natural foods, natural family planning and natural childbirth.  There’s the natural order, and second nature.  There are natural numbers.  There are all the examples I didn’t think of.  There are blog posts that are starting to sound like George Carlin routines.

The metaphysics of romantic love

Traditional natural law theory is often accused of reducing sexual morality to mere anatomy, the proper fitting together of body parts.  The charge is unjust.  To be sure, because we are animals of a sort, the natural ends of our bodily organs cannot fail to be partially definitive of what is good for us.  But because we are rational animals, our bodily goods take on a higher significance, participating in our intellectual and volitional powers.  These goods, the rational and the bodily, cannot be sundered or compartmentalized, because man is a unity, not a ghost in a machine.  Even eating participates in our rationality -- food becomes cuisine, and a meal becomes in the normal case a social occasion.  Sex is no different, and the ends toward which it is aimed by nature are as rational, as distinctively human, as they are bodily and animal.
