    Book Review

    Paul Davies,

    The Mind of God: Science and the Search for Ultimate

    Meaning,

    Simon & Schuster (cloth), New York, 1992; Penguin, London

    (paper), 1993. pp. 254, USDlO.

    In a mock entry from a university course guide, Woody Allen gives the

    following subject description:

    PHILOSOPHY XXIXB: Introduction to God. Confrontation with the

    creator of the universe through informal lectures . . . and field trips.

    The prescribed text for this course might well be Paul Davies recent

    best-seller

    The Mind

    of

    God,

    since the idea of finding God on field trips

    is essentially the project of Davies book. This is the traditional conception

    of a Natural Theology or the project which David Hume described

    as experimental theism in his

    Dialogues Concerning Natural Religion

    published in 1779. The conception of a Natural Theology or natural

    religion was one used by eighteenth century writers to refer to the en-

    terprise of finding rational arguments and evidence for religious claims

    a

    posteriori

    instead of establishing these claims through revelation

    a priori.

    In reviewing the book here, some reactions and reflections are prompted

    by the unlikely event of having found myself on the Australian Television

    ABC Lateline program as the atheist philosopher of science on the

    same side of an issue with a Jesuit priest and theologian, Father Tony

    Kelly. The issue on which we were united was our common cause as

    consumers who have been misled by false advertising for Paul Davies

    book. Like Father Kelly, I was led to believe that Davies book reveals

    new grounds for the belief in God from the truly remarkable developments

    in physics and cosmology. Undoubtedly for different reasons, we were

    disappointed to find something rather less than the sensationalistic PR

    had promised. The book has been hailed as providing dramatic evidence

    from the frontiers of science for the existence of an intelligent purpose

    behind the perceived order in the Universe. Not an altogether novel claim,

    it is true; but we had been expecting profoundly new insights into the

    ultimate question of origins, life, the universe and everything. If not quite

    meriting an expose by ABC televisions consumer watchdog program

    The Investigators, nonetheless, I feel that Professor Davies owes his

    consumers an explanation.

    The complaint against Davies is not new. In 1937 the philosopher L.

    Susan Stebbing in her book

    Philosophy and the Phys icists

    complained of

    the popularizations by Sir Arthur Eddington and Sir James Jeans that

    they constitute a grave danger to thinking clearly (Stebbing, 1937, p.

    13). She protests that Some of our scientific guides, writing in moments

    of emotional exaltation, have found it easier to mystify the common reader

    than to enlighten him. While conceding their unquestionable greatness

    BOOK REVIEW

    as scientists, Stebbing nonetheless complains bitterly of their popular,

    non-technical writings:

    But neither Sir Arthur Eddington nor Sir James Jeans seems to care

    very much whether his method of presenting his views concerning the

    philosophical significance of physical theories may not make it more

    difficult, or even impossible, for the common reader to understand what

    exactly it is that has been said. Both these writers approach their task

    through an emotional fog; they present their views with an amount of

    personification and metaphor that reduces them to the level of revivalist

    preachers. (Stebbing, 1937, p. 13)

    This colourful portrayal is undoubtedly too harsh and too exaggerated

    to apply to Davies writing, but there is an important point to be made

    nonetheless. It is striking to notice the parallels: Just as Jeans offered

    the latest developments in physics for the discussion of the ultimate

    philosophical problem so, too, Davies appeals to science in his search

    for ultimate meaning. Stebbing complains particularly about Jeans wish

    to use scientific knowledge as the basis for a quite different enterprise -

    namely, philosophy. She says:

    There is, however, a certain obscurity . . . in the remark science ought

    first to be asked to tell all she can. It suggests a final and higher court

    of appeal. This suggestion is misleading. (Stebbing, 1937, p. 15)

    Jeans, like Davies, portrays science as providing some grounds for belief

    in transcendent realities. However, Stebbing protests that Surprisingly

    little attention has been paid to the significance of the fact that the stupend-

    ous conclusions are supposed to be established by means of speculations

    based upon recent developments in the physical sciences (Stebbing, 1937,

    p. 23).

    Thus, Davies is among many scientists who have sought to go beyond

    the world revealed directly by science itself to the search for ultimate

    answers to the mystery of existence. Although he is clearly no New

    Age groupie, Davies speaks of mystical experiences and how they might

    provide the only route beyond the limits to which science and philosophy

    can take us, the only possible path to the Ultimate. Notwithstanding

    his cautious formulations and tentative speculations, Davies is taking a

    significant step beyond science into what he euphemistically calls meta-

    physics. Although he portrays this as a purely personal preference -

    seeing the glass as half full or as half empty, - and, therefore, as if it

    were not a substantive intellectual claim, here the physicist is taking a

    radical step into the realm of religion. Davies talk of mere preference

    for his view makes it sound as if it were a matter of indifference, there

    being no rational considerations for choosing one position rather than

    another. I believe that this is mistake. Talk of personal preference is

    perhaps a coy way of saying faith - a position held precisely because it

    is without rational warrant. It amounts to a concession - often explicit -

    4/13

    BOOK REVIEW

    that his view goes beyond what can be justified on scientific grounds as

    such, and, therefore, that his physics has no bearing at all on his belief.

    It is in this respect, ironically, that Davies, the quantum cosmologist

    and relativity physicist, is closer to the theologian. By going beyond sci-

    ence and outside the physical world (p. 171), and by preferring to see

    some cosmic purpose rather than meaninglessness, Davies has, in fact,

    endorsed the most popular, indeed the most notorious, argument for the

    existence of an intelligent God who made the world according to his divine

    plan. Calling this metaphysics as Davies has done is not an innocuous

    terminological matter and it should not disguise the character of the claim.

    In short, Davies new book is the most recent in the genre of Natural

    Theology based on the so-called Argument from Design.

    THE ARGUMENT FROM DESIGN

    Historically best known among these perhaps is William Paleys writing

    of 1802 which, like Davies book, is based on the conviction that the

    extraordinary order and pattern in nature could not be the result of

    mere chance. Paley employs the famous analogy of the intricately ordered

    mechanism of a watch which is evidence of the fact that its several parts

    are framed and put together for a purpose. Likewise, Paley argues, Every

    indication of contrivance, every manifestation of design, which existed in

    the watch, exists in the works of nature with the difference, he continues,

    that the contrivances of nature surpass the contrivances of art, in the

    complexity, subtlety, and curiosity of the mechanism. Echoing Paleys

    attitude, Davies, too, says Through my scientific work I have come to

    believe more and more strongly that the physical universe is put together

    with an ingenuity so astonishing that I cannot accept it merely as a brute

    fact. There must be, it seems to me, a deeper level of explanation (p.

    16).

    Paley was evidently unaware that his argument had been devastatingly

    rebutted by the philosopher David Hume twenty years earlier. Nearly

    three hundred years later, Davies makes no attempt to answer Humes

    criticisms either, though he aptly remarks It is all the more curious,

    therefore, that [the argument from design] has been resurrected in recent

    years by a number of scientists (p. 203). Curious indeed Especially since

    Davies himself does little more than re-state the apparent improbability

    of the innumerable, perfectly arranged conditions and to aver that it is a

    question of personal judgement.

    It is significant that Davies sees one problem in the difficulty of

    meusur-

    ing the

    degree

    of improbability of all the known coincidences. This is to

    miss the force of one of Humes counter-arguments. Granting even the

    highest degree of improbability, Hume asked: What would the world look

    like if it were, in fact, due entirely to chance? Clearly any world wil l

    look

    designed, however it came into being, and so it is not enough for advocates

    5/13

    204 BOOK REVIEW

    of the design argument like Davies to simply point to the remarkably

    ordered state of the universe. This is not a question of quantifying the

    degree of improbability, nor a question of personal judgement. It is the

    question of the plausibility of an inference which has not been strengthened

    one whit by the new evidence of modern physics since Paley. Paley already

    assumed the most complete and perfect design in the world and, therefore,

    the additional knowledge available since his time does not increase the

    force of his

    argument

    as such. The finely tuned physical constants imme-

    diately subsequent to the Big Bang are, in principle, no better evidence

    of design than the examples available to Paley.

    There can be no doubt about the awe-inspiring nature of the insights

    available from science which, as Davies rightly notes, has been the basis

    for frequent expression among scientists of a deep reverence and wonder

    akin to religiosity. Such feelings, however, must be sharply distinguished

    from their

    warrant

    for theological conclusions, though Davies pays too

    little attention to such crucial philosophical issues. Indeed, although Dav-

    ies is a superlative expositor of science, my enthusiasm for his work is

    tinged with misgivings. I do not wish to be ungenerous for, after all, the

    theology or metaphysics turns out to be an entirely secondary and inci-

    dental matter for Davies. Despite all the hype surrounding its promotion,

    in a book of over two hundred pages, barely a few pages altogether are

    devoted to these questions. Above all, Davies is correct in his view that

    insofar as the ultimate questions are meaningful at all and susceptible of

    any answers, then it is the enterprise of science which has been providing

    them. It is difficult, then, to reconcile this attitude with Davies apparent

    view that there can be some other enterprise to answer these questions.

    Thus, the very considerable virtues of Davies, popular book are, at the

    same time, its vice. Whereas the more overtly mystical and occult writings

    may be more readily relegated to New Age enthusiasm, it is precisely the

    scientific authority and respectability of Davies work which accords its

    underlying thesis an undue weight.

    Thus, I feel a certain ambivalence about Davies book since one could

    hardly wish for a better antidote to the persistent popularity of purveyors

    of paranormal. Sti ll, if the promotion and reception of Davies book are

    any indication, it is not the physics which is being enthusiastically dis-

    cussed, but its alleged support for the belief in an intelligent creator. The

    deep intellectual content may be in danger of being overlooked by the lay

    public in favour of its take-home message. The title of his book is an

    undeniably wonderful metaphor. But Davies own minimal preference for

    some highly attenuated principle behind the order in the world will be a

    subtlety lost on his audience. Though more apt, it is certain that if the

    book had been titled

    Modern Physics for the Layman

    it would have

    generated little excitement, nor prompted a special Easter edition of a

    TV current affairs program, inter alia. So my concern is occasioned by

    the alacrity with which Davies theological thesis has been seized upon

    despite the notorious inadequacy of the arguments themselves. Indeed, it

  • 7/25/2019 Review of Davies mind of God

    6/13

    BOOK REVIEW

    205

    must be said that Davies scarcely gives anything like an argument at all

    for the inference from the science to the metaphysics. The few gestures

    towards these questions do not even clearly reveal Davies own views until

    the end of the book where they are offered almost as a casual aside and

    afterthought. If it were not for the promotion of the book as a theological

    treatise one might have politely ignored its amateur philosophical perora-

    tions.

    However secondary to the book as a whole, Davies use of the term

    God does go significantly beyond mere metaphor, and in this regard he

    differs from other physicists who have spoken in similar ways. Most not-

    able among these, of course, is Einstein. Citing such scientists who have

    expressed a profound sense of awe for the apparent design in the universe

    is unobjectionable as far as it goes, but Davies neglects to indicate that

    atheism can be just as easily reconciled with these feelings as belief in an

    intelligent creator. In particular, although Einstein frequently and fam-

    ously referred to God as a way of expressing his views, these were little

    more than irreverent and striking metaphors. These references were

    merely the evocative personifications of a universe full of wonder but free

    of any purpose. Einstein spoke articulately of the experience of mystery

    and even of the Reason that manifests itself in nature but he left no

    doubt of his disdain for the idea of a God who rewards and punishes his

    creatures, or has a wil l of the kind that we experience in ourselves

    (Einstein, 1954, p. 11). Einstein spoke of the knowledge and emotions

    which constitute true religiosity as being the experience of mystery itself

    and the awareness and a glimpse of the marvellous structure of the

    existing world (Einstein, 1954, p. 11). It is important to notice that these

    sentiments do not seek to go

    beyond

    the apprehension of an order in the

    world or beyond the sense of mystery itself to anything else. It was in

    virtue of his possession of these non-transcendent feelings that Einstein

    emphasized that in this sense, and in this alone, I am a deeply religious

    man (Einstein, 1954, p. 11). Despite a common attempt to recruit Einstein

    to the cause of more traditional religious sentiments, his use of the term

    religious, just like the term God was slightly ironic rather than literal.

    He leaves no doubt of his meaning where he says

    The religious geniuses of all ages have been distinguished by the kind

    of religious feeling, which knows no dogma and no God conceived in

    mans image; . .

    . Hence it is precisely among the heretics of every age

    that we find men who were filled with this highest kind of religious

    feeling and were in many cases regarded by their contemporaries as

    atheists . . . (Einstein, 1954, p. 38)

    Elsewhere, Einstein explained that the attitude which he took to be

    religious in the highest sense of the word was derived from the experience

    of science itself and the striving for the rational unification of experience.

    Here Einstein says that the path to genuine religiosity does not lie

    through various fears or blind faith, but through striving after rational

  • 7/25/2019 Review of Davies mind of God

    7/13

    BOOK REVIEW

    knowledge. It is in this spirit that Einstein speaks of the intense experi-

    ence of successful intellectual advance through which one is moved by

    profound reverence for the rationality made manifest in existence. These

    are quite unambiguous statements of an uncompromising rationality which

    steadfastly refuses to go beyond the warrant of scientific reason itself.

    Despite its idiom, this attitude is diametrically opposed to the kind of

    transcendent mysticism which Davies embraces. A secondary, but perhaps

    telling, point is the fact that Davies has seemingly failed to see how widely

    Einsteins view diverges from his own. He lists Einstein among other

    notable scientists whom he describes as having also espoused mysticism

    (p, 226). This is an egregious misrepresentation of Einstein who expressed

    awe at the comprehensibility of the world, describing the comprehen-

    sibi lity itself as the greatest mystery.

    Above all, Einstein says that science purifies the religious impulse of

    the dross of its anthropomorphism (Einstein, 1954, p. 49). Of course, it

    is this anthropomorphism which is at the heart of the Argument from

    Design and it is crucial to notice that the apprehension of the design itself

    does not warrant any inference to an intelligent designer. The existence

    of order and regularity are not themselves evidence of such purpose, and

    Einstein addressed himself explicitly to this most common motivation for

    belief in a transcendent being, arguing on the contrary:

    The more a man is imbued with the ordered regularity of all events the

    firmer becomes his conviction that there is no room left by the side of

    this ordered regularity for causes of a different nature. For him neither

    the rule of human nor the rule of divine will exists as an independent

    cause of natural events. (Einstein, 1954, p. 48)

    In these remarks Einstein is clearly on the side of Hume against Davies,

    expressing a view which the philosopher Bertrand Russell called A Free

    Mans Worship - the reverence of an atheist. The view is sharply at odds

    with that of Davies, and my concern has been to suggest that the vast,

    undeniably wonderful insights of physics and cosmology do not warrant

    conclusions concerning intelligent purpose behind it all. To be blunt, for

    all the extraordinary sophistication of modern science, the argument is

    hardly better than the animism of primitive cultures which ascribed intell i-

    gence and purpose to trees and rocks. Whether applied to rocks or to the

    universe as a whole, the argument makes essentially the same analogy

    and is equally bad in both cases. Indeed, as Hume noted, it is arguably

    even more extravagant to compare the entire cosmos to human artefacts

    since the universe is not just one among other things with which it may

    be compared.

    The difficulties in Davies position are to be seen in the arbitrary scholas-

    tic distinctions he is forced to make once he has been prepared to counten-

    ance divine intervention or artifice in creating the universe according to

    some intelligent purpose. In his television remarks, Davies declined to

  • 7/25/2019 Review of Davies mind of God

    8/13

    BOOK REVIEW 207

    accept anything like the miracle of Christs resurrection on the grounds

    of the scientists preference for a world governed by strict, universal law

    - a good Humean answer. But one divine intervention more or less should

    make no difference. The possibility of an intelligent creation is no more

    consistent with the principles of science than the more mundane suspen-

    sions of the laws of nature. By accepting the possibility of metaphysical

    events transcending what can be known by science (p. 171), Davies has

    renounced the very principled intellectual grounds to which he appeals

    for rejecting miracles. Although Davies clearly prefers a highly attenuated

    notion of intelligent purpose, being just a little bit theological is like being

    a little bit pregnant. In the end, the difference between Professor Davies

    and the Jesuit priest is the difference between one big miracle and lots of

    little ones - a matter of minor theological disputation and who gets to

    wear the cassock. For a God who can make the whole universe in a Big

    Bang, the odd resurrection should be childs play.

    Of course, once we get into these questions of detail, there are many

    deep problems for the theologian, as Hume noted two centuries ago. Why

    monotheism? The existence of design does not support the inference to a

    single designer, since it could just as well have been a committee of gods.

    Likewise, Hume suggests that the assumption of perfection in the world

    is questionable, since we have no standard for comparison. Perhaps, Hume

    wrote, this world was only the first rude assay of some infant deity, who

    afterwards abandoned it, ashamed of his lame performance; it is the work

    only of some dependent, inferior deity; and is the object of derision to

    his superiors. Alternately, Hume suggests that the world might be the

    production of old age and dotage in some superannuated deity

    (Dia-

    logues, Part V, 1970, p. 53).

    SPIDERS BELLY?

    Davies emphasis on what he does best - that is, physics and cosmology

    - has perhaps caused him to overlook the relevance of other disciplines

    to his claims. Davies argument makes an appeal to a mind of some kind

    to explain the order in the world. But the phenomena of intelligence and

    purposive action are increasingly being understood through psychology,

    neuroscience and AI as complex, mechanical workings of animal and

    human brains. Even without the insights of modem cognitive science, it

    is hard to see how these biological phenomena could be seriously extrapol-

    ated as the mechanisms underlying the entire universe. The brain is not

    fundamentally more appropriate for such metaphysical purposes than any

    other organ, and the universe could with equal warrant be a cosmic

    kidney. This is the extravagant animism or anthropomorphism which

    Hume trenchantly criticized as the grossest and most narrow partiality

    by which we make ourselves the model of the whole universe

    (Dialogues,

    Part III, 1970, p. 38). He asks:

  • 7/25/2019 Review of Davies mind of God

    9/13

    208

    BOOK REVIEW

    . . .

    yet why select so minute, so weak, so bounded a principle as the

    reason and design of animals is found to be upon this planet? What

    peculiar privilege has this little agitation of the brain which we call

    thought, that we must thus make it the model of the whole universe?

    sound philosophy ought carefully to guard against so natural an

    illusion. (Dialogues, Part II, 1970, p. 28)

    Later in the Dialogues, Hume makes the same point with biting irony:

    The Brahmins assert that the world arose from an infinite spider, who

    spun this whole complicated mass from his bowels . . . Here is a species

    of cosmogony which appears to us ridiculous because a spider is a little

    contemptible animal whose operations we are never likely to take for

    a model of the whole universe. But still here is a new species of anal-

    ogy . . . And were there a planet wholly inhabited by spiders . . . this

    inference would there appear as natural and irrefragable as that which

    in our planet ascribes the origin of all things to design and intelli-

    gence . . . Why an orderly system may not be spun from the belly as

    well as from the brain, it wil l difficult for him to give a satisfactory

    reason. (Dialogues, Part VII, 1970, p. 67)

    As noted earlier, Davies expression of a mere preference suggests

    that his brief for a Creator is a rather attenuated one, having no particular

    probative force. But this disclaimer seems inconsistent with the fact that

    an argument is, after all, being offered. If his preference is to be anything

    other than blind faith which might distinguish the scientist from the aver-

    age church-goer, then Davies position is not a matter of indifference and

    arbitrary choice. The professed indifference cannot be reconciled with

    giving an argument supposedly gaining some cogency from modern phys-

    ics.

    PYROTECHNIC ENGINEERING

    Quite aside from the Argument from Design and its difficulties, the very

    question of the creation of the universe is not unproblematic. Davies

    certainly emphasizes the impossibility of reconciling traditional concep-

    tions of a Beginning and a Creator with modern physics, but it remains

    that he does not appear to rule out the very legitimacy of such questions

    as emphatically as others have done. Adolf Grtinbaum (1989), for exam-

    ple, has drawn attention to the importance of distinguishing the question

    of the origin of the universe from what he calls the pseudo-problem of

    its creation. Interestingly, the problem does not arise uniquely for big

    bang theories, since the out-of-favour steady state theory also required

    the formation of matter out of nothing and without external cause. It is

    noteworthy that modern cosmological theories can be seen to make more

    acute the difficulties of traditional First Cause arguments for the existence

    of God rather than make them more plausible. Despite the suggestiveness

    of a Beginning with its biblical overtones, recent physics makes a first,

    uncaused cause of the universe less believable. The problem arises from

    the illegitimacy of talking about causes or other events prior to the big

    bang. As Grtinbaum (1989) and Smith (1988) have noted, the concept of

    a cause itself is illegitimately extrapolated from the familiar notions of

    event and agent causation in the world to serve as explanation of the

    origin of the entire universe. This is, at the very least, an extension which

    requires defence, since it is not simply the unproblematic application of

    the ordinary notion of cause as it may appear. That is, the problem of

    the cause of the entire universe is not the same as the problem of the

    cause of any other event. First, as Grtinbaum (1989, p. 379) notes, there

    are vastly many cases of causation which do not involve human purpose

    or other conscious intentions of an agent. Therefore, even if one could

    legitimately posit an external cause of the entire universe, it by no means

    follows that such a cause must be the intentions of any conscious being

    or designer. The temptation to postulate causes of this kind is the sort

    of anthropomorphism or animism noted earlier. Second, and more funda-

    mental, ordinary agent causation involves only the

    transformation

    of mat-

    ter-energy and not its creation ex nihilo. Thus, the kind of cause being

    supposed to explain the origin of the universe is quite different from its

    everyday counterpart. For this reason, as Grtinbaum notes, the conclusion

    does not follow from the premise deductively. Nor is it even supported

    by it inductively (1989, p. 380).

    Davies is, of course, fully aware of these points (Davies, 1992, p. 58)

    but nonetheless he suggests with apparent equanimity that if one insists

    on a reason for the big bang, then this reason must lie beyond physics.

    However, it is not clear that there can be any rational appeal in this way

    beyond physics. The illegitimacy of supposing an external cause of the

    universe is essentially the same difficulty posed by any claims which go

    beyond what is strictly warranted by our best available scientific theories.

    The stratagem is a familiar one among proponents of the paranormal:

    our current scientific ignorance about some matters is taken to warrant

    extravagant conclusions about the inadequacy of science to deal with the

    phenomena in question. On this reasoning, we ought to posit revolutionary

    anomalies at the forefront of every scientific discipline.

    This difficulty confronts the very notion of a Creator of the universe

    who was responsible for the Big Bang since there was not only no matter,

    but no time before the Big Bang either. However difficult to comprehend

    in an intuitive sense, modem cosmological theories assert that the universe

    began to exist over ten bill ion years ago out of literally nothing, without

    being caused to do so. Smith (1988) explains . . . the singularity is not

    even an event, that is, a point in 4-dimensional space-time; it is not a

    part of but a boundary or edge of the 4-d-space-time continuum (1988,

    p. 48), and as Davies himself says, No special act of creation is needed.

    Paradoxically, in remarks such as this one, Davies book clearly offers a

    case as much for atheism as for the belief in God. Davies appears not to

    posit a creator in this sense contrary to the physics, but then it remains

    difficult to understand exactly how he conceives of the designer who is

    nevertheless somehow beyond or outside the physical world (p, 171).

    It is important to forestall a common misunderstanding which appears

    to give some comfort to laymen and which is encouraged by Davies. It

    will not do to mystify by referring to ultimate questions and metaphysics

    since these are empty labels without further explanation. Such remarks

    are commonly taken to imply that science has nothing to say about certain

    issues such as ultimate origins. However, this is misleading because mod-

    ern physics is not

    silent

    about causes of the universe prior to the Big Bang,

    it actually rules them out. Smith (1989, p. 51) explains this by analogy with

    the limitations upon our knowledge of events entailed by the Heisenberg

    Uncertainty Principle. The impossibility of knowledge in this case, too, is

    not due to our ignorance of the correct theory, but is a limitation upon

    possible knowledge actually specified by the theory itself. Grtinbaum, too,

    has emphatically made the point that questions such as What happened

    before t = O? or What caused the big bang? are based on assumptions

    which are denied by the model to which these questions are being posed.

    As Grtinbaum says, someone who seeks to pose such questions is entitled

    to reject the physical models in question by giving theoretically good

    reasons for postulating the existence of causes and times before t = 0.

    But, it is not possible to take the physics to be correct and, at the same

    time, to complain that the model fails to answer the questions which it

    actually rules out as illegitimate. Davies gives the appearance of wanting

    to have it both ways.

    Thus, while Davies gives a good exposition of the official answers pro-

    vided by the standard Big Bang theory on these questions (e.g. p. 48), it

    remains at the same time that he encourages precisely the kind of illegit-

    imate questions which Grtinbaum warns against. Playing on the very

    intuitions and assumptions which are denied by the theory, here and in

    his earlier book

    Superforce

    (1984) Davies repeatedly poses such question-

    begging puzzles to express dissatisfaction with the answers provided by

    the orthodox account. In sections whose very titles sin against Grtinbaums

    strictures (What Caused the Big Bang? and Did God Cause the Big

    Bang?), Davies persistently implies that there must be a genesis paradox

    or enigma requiring further explanation: We will not have explained the

    existence of the universe until we have traced the source of the primeval

    energy. Thus Davies speaks of a vital energy which triggered our universe

    into life (1984, p. 193) and he questions the adequacy of the official

    answer, since We can still ask how the vacuum acquired the energy in

    the first place. These locutions in terms of triggering and what must

    have happened in the first place clearly encourage the very conceptions

    which we saw Grtinbaum protest against.

    Half a century ago, Stebbing accurately diagnosed Davies quest for

    ultimate meaning when she said that physicists of her time, like those of

    the nineteenth century, were apt to suffer from

    the defect of a

    too

    hasty passage from physics to metaphysics (Stebbing, 1937, p. 197). More

    particularly, she cites the new tendency towards idealism as an unwar-

    ranted inference from the abandonment of nineteenth century concep-

    tions. Undeniably, the revolutionary advances of the twentieth century

    appear to have suggestive affinities with non-materialist philosophies.

    These affinities are what Arthur Koestler (1972) mischievously called a

    negative rapprochement whereby the strange conceptions of quantum

    physics and relativity theory appear to give some warrant or excuse for

    the truly bizarre claims of parapsychology. This is a piece of sophistry and

    a play on words since, however different from the materialistic, mechanis-

    tic theories of the nineteenth century, the new physics provides no more

    support for paranormal or mystical claims than the earlier physics. Davies

    explicitly invoked the same spurious, if suggestive, arguments in his earlier

    book (Davies, 1983, p. 8). Echoing Koestler, Davies wrote that with the

    revolution in their subject, modern physicists seemed to turn common-

    sense on its head and find closer accord with mysticism than materialism.

    I believe that, in the end, Davies book is misleading because of its

    ambivalence. The irony is that, apart from its obiter dicta, its actual

    substance could just as easily be construed as an eloquent case for atheism.

    Its very reticence on the metaphysical questions is a disservice since its

    theology is insinuated rather than argued. Davies and like-minded physi-

    cists might make it clearer that they do not speak in their capacity as

    scientists when they express their preference for metaphysical answers

    to ultimate questions. A more appropriate stance on such questions is

    to argue for them openly or to acknowledge their illegitimacy. The notion

    that we might meaningfully go beyond what our best science itself can

    certify is highly suspect and would require more defence than Davies

    gives. The appropriate humility would refuse to even ask questions which

    are actually ruled out by our science. In this regard, I concur with David

    Humes sentiment: . . . I cannot, for my part, think that so wild and

    unsettled a system of theology is, in any respect, preferable to none at

    all (Hume, 1779/1970, p. 53). Or, as Wittgenstein famously wrote in his

    Tractatus,

    Whereof one cannot speak, thereof one should remain silent.

    More prosaically perhaps, the attitude is captured best by a Woody Allen

    character when asked a deep question about the meaning of it all; he

    replies How should I know? I cant even figure out how this can-opener

    works
