The humanities and the
natural sciences are equally important in trying to make sense of the
world. However, neither approach
can claim “the advantage of being in touch with the world as it is apart from
anyone’s beliefs, allegiances, assumptions and theories.” (http://ow.ly/bNbUc)
And yet some of the most
prominent scientists publishing today seem to believe that science provides
wise insights into the world based on experiments conducted by logical,
rational methods, while the humanities (religion and philosophy for example)
rely on dogma, irrational faith, authority, subjectivity, and trust. Academic superstars such as Richard
Dawkins, Steven Pinker, Daniel Dennett, Lawrence Krauss, Stephen Hawking,
Richard Feynman, and John Gray come immediately to mind.
Two recent public
dustups have highlighted the unnecessary tension between science and the
humanities that reflects much modern academic thought. In one quarrel, philosophy and physics
squared off over a negative book review of Krauss’ A Universe From Nothing:
Why There is Something Rather Than Nothing. (http://ow.ly/bNbXU) In the other dispute, Dawkins and Pinker on a MSNBC
Sunday talk show exhibited the smug triumphalism of famous scientists who know
that their approach explains everything and that “religion clouds the minds of
those who, if they were only sufficiently educated, would arrive at the
conclusions supported by the overwhelming preponderance of scientific evidence and
reject the blind adherence to revealed or ecclesiastical authority that
characterizes religious belief” about global warming. (http://ow.ly/bNc0D)
David Albert, a
philosopher with a Ph.D. in theoretical physics, wrote the New York Times book
review that criticized Krauss for writing “that the laws of quantum mechanics
have in them the makings of a thoroughly scientific and adamantly secular
explanation of why there is something rather than nothing.” Albert draws attention
to the battle lines between physics and religion by quoting Dawkins who wrote
in the afterword to the book, “Even the last remaining trump card of the
theologian, ‘Why is there something rather than nothing?’, shrivels up before
your eyes as you read these pages.
If ‘On the Origin of the Species’ was biology’s deadliest blow to
supernaturalism, we may come to see ‘A Universe From Nothing’ as the equivalent
from cosmology. The title means
exactly what it says. And what it
says is devastating.” (http://ow.ly/bNbXU)
Albert is just as
devastating in pointing out that Krauss does “not have a clue about” where the
laws of quantum mechanics come from.
The fundamental laws of nature have “simply taken it for granted that
there is, at the bottom of everything, some basic, elementary, eternally
persisting, concrete, physical stuff…But the laws have no bearing whatsoever on
questions of where the elementary stuff came from, or of why the world should
have consisted of the particular elementary stuff it does, as opposed to
something else, or to nothing at all.”
After explaining why Krauss does not really understand
relativistic-quantum-field-theoretical vacuum states, Albert ends his review
with, “It seems like a pity…to think that all that gets offered to us now, by
guys like these, in books like this, is the pale, small, silly, nerdy
accusation that religion is, I don’t know, dumb.” (http://ow.ly/bNbXU)
Krauss called Albert
“moronic” and is described as believing that “philosophy, unlike physics, makes
no progress and is rather boring, if not totally useless.” In this assessment, Krauss seemed to
agree with Hawking’s declaration that philosophy is “’dead.’” (http://ow.ly/bNc6K)
Stanley Fish explores
similar themes because he watched the talk show where the host asked the
question, “If you hold to the general skepticism that informs scientific
inquiry…how do you respond to global-warming deniers…when they invoke the same
principle of open inquiry to argue they should be given a fair hearing.” Dawkins responded that in science you
can quote Professor So-and-So’s 2008 study, “’you can actually cite chapter and
verse.’” (http://ow.ly/bNc0D)
Fish pounces by noting
that Dawkin’s argument is “circular and amounts to saying that the chapter and
verse we find authoritative is the chapter and verse of the scripture we
believe in because we believe in its first principle, in this case the adequacy
and superiority of a materialist inquiry into questions religion answers by
mere dogma.” ((http://ow.ly/bNc0D
“With
this proverbial phrase, Dawkins unwittingly (I assume) attached himself to the
centuries-old practice of citing biblical verses in support of a position on
any number of matters, including, but not limited to, diet, animal husbandry,
agricultural policy, family governance, political governance, commercial
activities and the conduct of war.
Intellectual responsibility for such matters has passed in the modern
era from the Bible to academic departments bearing the names of the enumerated
topics. We still cite chapter and
verse – we still operate on trust – but the scripture has changed (at least in
this country) and is now identified with the most up-to-date research conducted
by credentialed and secular investigators.” ((http://ow.ly/bNc0D
I have written
before about the assumptions all scientists make about the world we are trying
to understand when we do science. (http://ow.ly/bNcdw)
“The astronomer John Barrow notes ‘the practice of
science…rests upon a number of presuppositions about the nature of reality.’ He
identifies nine such presuppositions:
▪
The external
world is external to our minds and is the source of our sensations.
▪
The external
world is rational
▪
The world be
analyzed locally without destroying its structure
▪
The
elementary entities do not possess free will.
▪
The
separation of events from our perception of them is a harmless simplification
▪
Nature
possess regularities which are predictable
▪
Space and
time exist
▪
The world can
be described by mathematics
▪
These
presuppositions hold in an identical fashion everywhere and every when.
(The World Within the World, New York: Oxford University Press,
1988).”
Fish also understands that
religious believers and scientists both operate by assuming things, albeit
different things, about reality
People
like Dawkins and Pinker do not survey the world in a manner free of assumptions
about what it is like and then, from that (impossible) disinterested position,
pick out the set of reasons that will be adequate to its description. They begin with the assumption (an act
of faith) that the world is an object capable of being described by methods
unattached to any imputation of deity, and they then develop procedures… that
yield results, and they call those results reasons for concluding this or that. And they are reasons, but only within
the assumptions that both generate them and give them point. (http://ow.ly/bNc0D)
Although readers responded by
“pouring the proverbial ton of bricks on my head,” Fish held his ground in a second
blog posting. Fish points out that
both science and the humanities work.
Therapy “enhances the ability to socially interact, at least sometimes,”
and religion “gives meaning and direction to life, at least for some people.”
“The…qualifications in the previous sentence acknowledge that the certainty
these practices give us is, at least from the perspective of the long run,
provisional.” (http://ow.ly/bNbUc)
But as I have written before the
truths of science are provisional as well. (http://ow.ly/bNcdw)
“Lys Ann Shore and Karl Popper add to my doubts that
science will tell me what is really going on. Shore has written, ‘The quest for
absolute certainty must be recognized as alien to the scientific attitude,
since scientific knowledge is fallible, tentative, and open to revision and
modification (Hagen, 1995).’
The Stanford Encyclopedia of Philosophy summarizes
Popper’s philosophy of science (http://plato.stanford.edu/entries/popper/):
‘Scientific theories, for him, are not inductively
inferred from experience, nor is scientific experimentation carried out with a
view to verifying or finally establishing the truth of theories;
rather, all knowledge is provisional, conjectural, hypothetical—we can
never finally prove our scientific theories, we can merely (provisionally)
confirm or (conclusively) refute them; hence at any given time we have to
choose between the potentially infinite number of theories which will explain
the set of phenomena under investigation. Faced with this choice, we can only
eliminate those theories which are demonstrably false, and rationally choose
between the remaining, unfalsified theories. Hence Popper’s emphasis on the
importance of the critical spirit to science—for him critical thinking is the
very essence of rationality. For it is only by critical thought that we can
eliminate false theories, and determine which of the remaining theories is the
best available one.’
Popper
thought there are only two kinds of scientific theories: those that have been
proven to be wrong and those that have yet to be proven wrong.”
The humanities and the natural
sciences are both useful in my quest to better understand the world I find
myself living in. In Part II of
this blog post, I will examine the backlash of some humanists who reject the
prevailing conventional modern wisdom that science explains everything.
