Edward Feser with a terrifically chippy review of a Lawrence Krauss book in First Things...
A critic might reasonably question the arguments for a divine first
cause of the cosmos. But to ask “What caused God?” misses the whole
reason classical philosophers thought his existence necessary in the
first place. So when physicist Lawrence Krauss begins his new book by
suggesting that to ask “Who created the creator?” suffices to dispatch
traditional philosophical theology, we know it isn’t going to end well...
Ouch...
Krauss simply
can’t see the “difference between arguing in favor of an eternally
existing creator versus an eternally existing universe without one.” The
difference, as the reader of Aristotle or Aquinas knows, is that the
universe changes while the unmoved mover does not, or, as the
Neoplatonist can tell you, that the universe is made up of parts while
its source is absolutely one; or, as Leibniz could tell you, that the
universe is contingent and God absolutely necessary. There is thus a
principled reason for regarding God rather than the universe as the
terminus of explanation.
One can sensibly argue that the
existence of such a God has not been established. (I think it has been,
but that’s a topic for another day.) One cannot sensibly
dispute that the unchanging, simple, and necessary God of classical
theism, if he exists, would differ from our changing, composite,
contingent universe in requiring no cause of his own.
Krauss’
aim is to answer the question “Why is there something rather than
nothing?” without resorting to God”and also without bothering to study
what previous thinkers of genius have said about the matter. Like
Richard Dawkins, Stephen Hawking, Leonard Mlodinow, and Peter Atkins,
Krauss evidently thinks that actually knowing something about philosophy and theology is no prerequisite for pontificating on these subjects. Nor is it merely the traditional theological answer to the question at
hand that Krauss does not understand. Krauss doesn’t understand the
question itself...
Why are "smart" people so often tempted to do this?
The bulk of the book is devoted to exploring how the
energy present in otherwise empty space, together with the laws of
physics, might have given rise to the universe as it exists today. This
is at first treated as if it were highly relevant to the question of how
the universe might have come from nothing”until Krauss acknowledges
toward the end of the book that energy, space, and the laws of physics
don’t really count as “nothing” after all. Then it is proposed that the
laws of physics alone might do the trick”though these too, as he
implicitly allows, don’t really count as “nothing” either.
His final proposal is that “there may be no fundamental theory at all”
but just layer upon layer of laws of physics, which we can probe until
we get bored. But this is no explanation of the universe at all. In
particular, it is nowhere close to what Krauss promised his reader”an
explanation of how the universe arose from nothing ”since an endless series of “layers” of laws of physics is hardly “nothing.” His book is like a pamphlet titled How to Make a Million Dollars in One Week that turns out to be a counterfeiter’s manual.
The helpful distinction between narrative/story and explanation-- or simply a coherent and consistently-applied definition of explanation-- would keep Krauss out of trouble.
The spate of bad books on philosophy and religion by prominent scientists”Dawkins’ The God Delusion , Hawking and Mlodinow’s The Grand Design , and Atkins’ On Being
, among others”is notable not only for the sophomoric philosophical and
theological errors they contain but also for their sheer repetitiveness
. Krauss’ fallacious account of how something can come from nothing,
though presented as a great breakthrough, and praised as such by Dawkins
in his afterword, is largely a rehash of ideas already put forward by
Hawking, Mlodinow, and some less eminent physics popularizers. Dawkins
has been peddling the “Who created the creator?” meme since the
eighties.
Critics have exposed their errors and fallacies
again and again. Yet these writers keep repeating them anyway, for the
most part simply ignoring the critics. What accounts for this? To
paraphrase a famous remark of Ludwig Wittgenstein’s, I would suggest
that a picture holds these thinkers captive, a picture of the
quantitative methods of modern science that have made possible
breathtaking predictive and technological successes.
What
follows from that success is that the methods in question capture those
aspects of reality susceptible of mathematical modeling, prediction, and
control. It does not follow that there are no other aspects of reality.
Again, hubris and basic errors in logic...
But as E. A. Burtt noted over half a century ago in his classic book The Metaphysical Foundations of Modern Physical Science
, the thinker who claims to eschew philosophy in favor of science is
constantly tempted “to make a metaphysics out of his method,” trying to
define reality as what his preferred techniques can measure rather than
letting reality dictate what techniques are appropriate for studying it.
He is like the drunk who thinks his car keys must be under
the lamppost because that is the only place there is light to look for
them”and who refuses to listen to those who have already found them
elsewhere.
Without a trace of irony, Krauss approvingly cites
physicist Frank Wilczek’s unflattering comparison of string theory to a
rigged game of darts: “First, one throws the dart against a blank wall,
and then one goes to the wall and draws a bull’s-eye around where the
dart landed.” Yet that is exactly Krauss’ procedure. He defines
“nothing” and other key concepts precisely so as to guarantee that only
the physicist’s methods he is comfortable with can be applied to the
question of the universe’s origin”and that only a nontheological answer
will be forthcoming.
And then the ironic punchline:
To the centuries-old
debate over why any universe exists at all, Krauss’ book
contributes”precisely nothing.
