Disclaimers, guidelines, policies and the like

With the publication of IBM’s blogging policies, there’s been a fair amount of discussion on the internal Sun bloggers’ alias about our own policy. Tim Bray has a piece on the subject over at ongoing. I’ve never bothered with a disclaimer on this blog, since (1) it’s not hosted at blogs.sun.com or any other Sun site, and (2) I have always felt that if a lawyer was out to get you, the degree of protection provided by a disclaimer would fall in the category “None at all”.* Nonetheless I have reluctantly decided to follow my colleague, and have shamelessly plagiarised the disclaimer from ongoing. I’ve also taken the opportunity to reorganize the sidebar, eliminate a few placeholders that I never got around to creating content for, and generally do a bit of spring cleaning.

My next laptop for Solaris?

Tulip have announced a rather unusual laptop. It’s based on the new AMD Turion CPU, the successor to the Athlon 64, so it should run Solaris 10 in 64 bit mode quite nicely. However what caught my eye was the limited edition Tulip E-Go Diamond version, which has some “unusual” styling touches:

“Tulip E-Go notebook inlaid with solid palladium white gold plates in which thousands of brilliant cut diamonds have been set. The quality is V.V.S. top-Wesselton and the total weight is 80.00 Crt. The brilliant cut diamonds are microscopic and pave set with surgical precision. This magnificent end result is possible thanks to the use of brilliant cut diamonds with a large variety of diameters. A unique square cut ruby has been set in both Tulip logos. For the Tulip E-Go diamond project, Marcel van Galen Design worked closely together with Design Department product engineering and Laurent de Beer Master Jewelry Designer. Consumer price € 283,000

Book recommendation: Japanese Graphics Now

While visiting the Museum of Fine Arts on Saturday, I picked up a Taschen book called Japanese Graphics Now. cover of bookA big, handsome coffee-table tome (600 pages, around $40) covering all aspects of contemporary Japanese graphic design. And the piece de resistance: “We’ve also thrown a DVD into the package, on which you’ll find a video tour of the coolest places to visit in Tokyo, interviews with art directors, filmmakers, and designers, and the latest and greatest television commercials from Japan.”

(The Suntory “cherubim” commercials are delightfully bizarre, as is the one for WOWOW. As for the video tour of Tokyo, it brought back so many memories for me…..)

Refuting the argument from fine tuning

In my earlier posting about Antony Flew’s Introduction to God and Philosophy, I noted that Flew had identified the “argument from fine tuning” as a “development” which future authors in this area should take into account. In this post, I want to explain what this argument involves, and why it is completely devoid of merit.

The argument from fine tuning is a derivative of the argument from design. (It is also one of several theories that have been associated with the phrase “anthropic principle”, but since this term has been applied to various mutually contradictory theses, wise people will avoid it.) One of its chief proponents is the former astronomer Hugh Ross. A summary version of the argument runs as follows:

There are many fundamental parameters in physics which determines what kind of a universe this is. Examples include the Plank’s constant, the mass and charge of the electron, the gravitational force constant, the speed of light, and many others. It turns out that if some of these numbers are slightly different than their actual values, our universe would not be able to support life. It is virtually impossible that the universe came to have these correct parameters for life by chance, because so many of these numbers must all lie in such a small range of values. So it appears that the constants of the universe were fine-tuned for life. The being who did this fine-tuning must be God; without such a being, there would be virtually no chance that life could exist. *

At first glance, it is tempting to argue against this proposition on its own terms, by examining the actual values of cosmological and physical constants and calculating whether or not the proposition describes the circumstances accurately. The web site from which this quotation is drawn cites one such argument, and goes into great detail to refute it. However this is (mostly) beside the point, for the following reason:

Every intelligent species that observes the universe that it lives in will find that the constants of its physical and cosmological models of this universe appear to be fine-tuned to support its own life – even if these constants are radically different from those in another universe, such as ours. If the constants of a particular universe are such that life is not possible, there will simply be no species to observe this fact. And we have no a priori reason to say how many possible universes fall into each category, and therefore no basis for asserting how likely or unlikely life is.

Consider the following thought experiment. In another possible universe, the cosmological and physical constants are such that large dense bodies such as planets cannot form; instead, stars are surrunded by shells of gas. Stable patterns can form in this gas due to some resonance phenomenon, and over time self-replicating patterns emerge. Since this patterns can change, and gas resources are finite, Darwinian evolution will occur, and one may suppose that in time intelligence may arise. Such cloud-creatures might develop cosmology and physics, and may think to themselves, “How fortunate we are that the constants of the universe are so finely tuned. If they were slightly different, solid planetary bodies might form that would gravitationally disrupt our fragile forms; life as we know it would be impossible!”

The proponents of the argument emphasize the “fine” in “fine tuning”, but this seems unwarranted. In any universe, every system of cosmological and physical science devised by a sentient species will include a wide range of constants and other fundamental properties. Some of these will be such that the overall system is particularly sensitive to their values; for others, the precise values will be relatively unimportant. Chance alone will dictate that some of these constants will seem to be finely balanced. Since these properties are largely emergent and are likely to be contingent in ways that we do not understand today, this “balance” may well be completely illusory. **

So where does this leave us? Every intelligent life form in any universe will necessarily perceive a “fine tuned” situation, whether it is true or not. There is no reason to believe that there is only one type of universe that might support life, no way to observe those universes that do not, no way to assess the significance of particular constants. (Indeed the argument is consistent with the hypothesis that a malevolent designer is manipulating physical constants to reduce the probability of life!) The bottom line is that the argument is a bust. It purports to derive an ontological statement from a contigent epistemological argument, but the unquantifiable character of the argument renders it meaningless.


* I struck out the final sentence because it is such a grotesque non-sequitur that I’m sure no reasonable person would want to be associated with it.

** In his important new book A Different Universe – reinventing physics from the bottom down, the Nobel physicist Robert Laughlin makes the point that many of the “laws” of chemistry and physics are dramatically insensitive to precise numbers, pure samples, and other properties that we might expect to be important. Since we only know the large-scale properties of one universe – this one – we are on very shaky ground if we presume certain kinds of sensitivity.

Antony Flew: at last, the book

The story so far…

Last year there was a flurry of media attention around the “revelation” that Antony Flew, the British philosopher, had renounced his lifelong atheism and now believed in god. The main impetus for this was the publication of a book and video of a “debate” between Flew and a number of Christian writers and philosophers. In response to questions from various people, Flew made a number of comments, which I documented in previous blog entries. He also advised people to wait for the new edition of his 1966 book God and Philosophy, and promised that the new introduction to that book would answer all questions. I have now obtained a copy of this. Now read on….

First, a comment on the book itself. It was out of print, and has now been reissued by Prometheus Books. Apart from a Publisher’s Forward and the new Introduction, the text is unchanged, so if you already have God and Philosophy (also published as God: A Critical Enquiry) you should only buy this if you really have to have the new Introduction – 7 pages, plus a page of end-notes. As for the place of this book in a library of the philosophy of religion, I’d recommend it only for “completists”; it has largely been superceded by newer treatments of the subject.

“But what does he say in the Introduction?”, I can hear you asking. The short answer is: nothing earth-shattering. Flew does not claim any particular position, whether atheist, desist, theist, or whatever. (Indeed if it were not for the Publisher’s Forward by Paul Kurtz of SUNY Buffalo, there would be little reason to pay much attention to the Introduction.) Rather, Flew lists a number of recent developments which “any intending successor to God and Philosophy would need to take into account”, but without indicating whether such developments have caused him to change his position. As Kurtz notes, there were four drafts of the Introduction submitted to Prometheus, and “it is up to the readers of his final introduction published below to decide whether or not he has abandoned his earlier views.”

Those who were looking for a definitive answer to l’affaire Flew can stop reading here. Those who would like to dig for clues will presumably want to learn which “recent developments” Flew considers significant. Let’s examine them in order.

  • Flew first draws attention to the “multiverse” theory, citing Geneziano and Paul Davies. He doesn’t explain why this is relevant, and in re-reading his treatments of the Cosmological Argument and other classical moves, I couldn’t see how they would be changed by replacing the Big Bang by a multiverse model. (One form of the multiverse idea would rehabilitate the notion of an infinite chain of causation. Since this would presumably remove any need for an “uncaused cause”, it wouldn’t give comfort to any theist.)

  • Secondly, Flew raises the “fine tuning argument”. His choice of words is careful, yet disturbing: he simply says that “whatever [its] merits or demerits, it must… be allowed that it is reasonable [for believers in theistic religions] to see [it] as providing substantial confirmation of their own antecedent religious beliefs.” But this, surely, is beside the point: believers have many reasons for their positions which are wholly out of the scope of rational inquiry. The fine tuning argument would only be relevant to a successor to God and Philosophy if it constituted a substantial move in the debate. And it doesn’t: it is a wholly specious proposition that falls apart under even a cursory examination. (I’ll defend this position in a subsequent blog posting, for reasons of space.)

  • The third point that Flew raises is that of abiogenesis: how the first forms of life on Earth might have arisen from inanimate matter. Flew is “delighted to be assured” that science has this question in hand, and cites Richard Carrier’s excellent papers on the subject.

  • The fourth “development” is puzzling. Flew simply draws attention to Roy Abraham Varghese’s book The Wonder of the World, and says that it “provides an extremely extensive argument of the inductive argument from the order of nature”. Now Flew’s review of this book is on the web. In it, he wrote “until a satisfactory naturalistic explanation has been developed, there would appear to be room for an Argument to Design at the first emergence of living from non-living matter…. You have in your book deployed abundant evidence indicating that it is likely to be a very long time before such naturalistic explanations are developed, if indeed there ever could be.” Thereafter Flew noted that his views diverged with Varghese. Yet just above we noted that Flew was “delighted” that the scientific accounts of abiogenesis were in good order. So which is it?

  • The fifth “development” cited by Flew is a “revival”, due to David Conway, of “the classical conception of philosophy” and the Aristotelian notion of god. If one re-reads the original text of God and Philosophy, it seems that Flew has already considered all of the points that he raises (at inordinate length) in this “development”; there is, literally, nothing new here.

  • Finally, Flew says that “mention must be made of the radically new and extremely comprehensive case for the existence of the Christian God made by Richard Swinburne in his Is There a God? Radically new? Why haven’t we been told?! In fact, as Flew is forced to admit, Swinburne’s argument, “is, like the fine tuning argument, something that [believers] may very reasonably see as… confirmation.” For myself, I found Swinburne’s arguments remarkably unoriginal: he merely recycles the Paley argument for design and then makes an unsupported move from designer to personal montheistic deity.

So what’s the verdict? My reading is that Flew got drawn into an unsustainable position, realized his mistakes (as noted in my earlier blog entries), backed off, and removed anything controversial from the Introduction. However he still felt compelled by duty of friendship to give a favorable reference to those that he corresponded with during 2004: Varghese, Swinburne, and Conway. The end result, despite Paul Kurtz’s attempt in the Forward to whip up a controversy, is a damp squib. Oh, well.

Another vaguely philosophical web quiz

Seems a bit over-simplified to me, but never mind….

You scored as Materialist. Materialism stresses the essence of fundamental particles. Everything that exists is purely physical matter and there is no special force that holds life together. You believe that anything can be explained by breaking it up into its pieces. i.e. the big picture can be understood by its smaller elements.

That atheistic theory of freezing water….

Nice cartoon in Salon today by Ruben Bolling: Creationists challenge the teaching of water’s freezing point. (As usual, click the thumbnail to view it. If you’re not a Salon subscriber, you may have to jump through a small hoop.)cartoon thumbnail
The punch line: The creationists found unlikely support among students in China and India. "Yes, America, we would like very much if you would teach your children religious dogma instead of science. We'd like their jobs."

Texan infidels

In her blog, Eike Rathke of the OpenOffice team skewers the idiots in Texas who want to ban suggestive cheerleading: “Why don’t they just burn some of them as it would be appropriate in God’s own country obeying God’s own laws?” Indeed. If you really believe in infallible, unalterable religious texts, you can’t afford to pick and choose.
