Last Wednesday BBC 1 aired a factual programme by the Commonwealth’s Chief Rabbi, the Right
Honorable Lord Jonathan Sacks. It was entitled ‘Rosh
Hashanah: Science vs Religion’. As a
result of watching this programme and after having had a number of discussions
and heated arguments with people regarding the utility of science for
understanding reality, I want to explore a few things about this argument in
this blog post. I am afraid it is ranty
in nature. For this, I apologise. (Update: I can no longer find programme on iPlayer- so please excuse my lack of linking)
In the program, Lord Sacks met with three
scientists to discuss whether science and religion could not only coexist
peacefully on the same intellectual landscape, but whether they should strive
to actively work together to understand the nature of the universe and the
human condition. As part of his
investigation into whether science and religion could ever make happy
bedfellows, Sacks met with ‘neuroscientist’ Baroness
Susan Greenfield, ‘physicist’ Jim Al-Khalili and ‘evolutionary biologist’ Richard
Dawkins. (Their respective
‘fields’ are noted as such because they are probably all better known as
science communicators rather than full-time research scientists these days. It’s
not because I think they’re crap).
The scientists met with Sacks in various
corners of London, including the gorgeous Royal Society building, to chat about
such matters. What followed were three perfectly polite, accommodating and
anodyne conversations between scientist and rabbi. Nobody came across as a bigoted
pillock (heaven forbid) and the whole affair was quite civilized and British.
The problem is that, while civility and politeness are very decent ways of
ensuring calm and reasoned discussions, the whole exercise was frustratingly
insipid. No one said anything that properly addressed the very serious and real
questions of whether science and religion can both offer equally valuable
solutions to the conundrums society faces today or whether they should be
accorded equal respect in this case.
So I intend to delve a little deeper into
some of the outcomes of the conversations in that programme. I am sure the scientists
and the Chief Rabbi will be profoundly grateful for this enlightened
intervention.
I intend to rant about three specific
points that were made (or at least implied) during the show, which were not
given due care and attention in my arrogant opinion. My rants will ultimately
lead to my assertion that science must
be accorded hegemony in our quest to understand our universe.
The first question that I want to address,
and indeed one of the first questions Lord Sacks asked when he went to visit
Baroness Greenfield is: can science really understand human consciousness?
As a
neuroscientist, Greenfield was well placed to give an expert account of why the
realm of the human mind is fully accessible to scientific investigation. Unfortunately, this was not the case and
Greenfield merely hinted that even if understanding consciousness was a fully
tractable scientific problem, she was happy to accept that “science and
religion could both be different sides of the same coin” when we consider how
best to appreciate the intricacies of human consciousness.
Firstly, it would be entirely reasonable to
assume (and indeed essential to point out in this case) that understanding the
existence of consciousness is a highly achievable goal when we rely on science
alone. However, it may not be possible
to gain a full and comprehensive understanding at this particular moment in time.
Scientific breakthroughs don’t just happen when individuals have amazing
insights; they also happen when breakthroughs in technology and machinery allow
us to delve deeper into the universe (or any given system or phenomenon) than
before. When we can start probing at
ever smaller or larger scales, or can contemplate problems with ever-greater
computational complexity, we can start to understand things that were hitherto
inaccessible to us. It is reasonable to assume that neuroscience will
eventually benefit from such developments.
Therefore, future advances in functional
MRI combined with deeper insights into the physics of complex networks, will
yield more clues to the nature of how our minds work. When we combine these achievements with the
ability to model what happens in and between neurons, and gain a fuller
understanding of the evolution of consciousness in humans and other animals, we
will have the eventual ability to model human consciousness and understand its
nature and even its origins. This may
not happen tomorrow or even in the next ten years, but that does not mean that
science won’t eventually provide us with a valuable synthesis of knowledge
about the workings of the mind.
Furthermore, our understanding of
consciousness in the context of the human species (rather than the ‘human
creation’ made separate from animals) will hopefully go a long way to
solidifying what has been patently apparent for some time- that animals have
levels of consciousness, or at least similar underlying mechanisms that form
the basis of conscious thought that are entirely similar to ours. This shouldn’t come as a surprise at all given
that we are animals and our
evolutionary history can be charted all the way back to the last universal
common ancestor of the eukaryotes (at least).
Yet, I have had arguments with people (and attended talks by eminent
‘thinkers’) where they have flat-out denied that consciousness is a tractable
problem for evolutionary biology (or science in general).
That consciousness is complex and
remarkably difficult to model, and that it gives rise to subjective thought and
appreciation does not mean it is beyond the reach of empiricism. Just because we currently assume that human
consciousness is infinitely richer and more profound than ‘animal’
consciousness, this doesn’t mean it has to have come from somewhere other than
natural selection either.
Raymond Tallis, the “poet, cultural critic,
philosopher and [ex]-physician” actually claimed during a talk of his that
“something like human consciousness would never be selected for by evolution”.
Not only did this sadly demonstrate a terrible misunderstanding
regarding the passivity of natural selection as a process, but also seemed to
stem from an assumption that consciousness exists outside, or beyond the
entirely map-able, dissectible and model-able structures of brain tissue! If brain tissue is thoroughly accessible to
scientific investigation then arguably, so is consciousness. For this not to be true, consciousness will have
to exist somewhere beyond the confines of our brains. Perhaps that’s why Paris
Hilton favors such ridiculously large handbags…
An
entirely empirical understanding of the true nature of human thought and its
influence on our behaviour may also have profound consequences for how we
understand psychoses and other neurological conditions. It may come to
influence how we punish (or rehabilitate!) psychopaths when they murder people,
or how we define future crime and punishment systems in general. It may yield remarkable and vital insights
into human suffering that would provide us with a much stronger understanding
of the human condition than intuition or experience can provide. Therefore, it
is essential to use science to understand consciousness. Science will provide us with a far more
accurate synthesis of knowledge than insight or philosophy ever could.
I would also argue that understanding human
consciousness as a divine creation instead of a biological one will always
result in us relegating our fellow non-human animals to more lowly ranks, less
deserving of compassion. This will suck
for animal welfare.
The next point stems from the conversation
Lord Sacks had with Jim Al-Khalili: Both happily reached the conclusion that
they felt a sense of wonder at the enormity and majesty of the universe. They
agreed that they really only differed in their views where Sacks questioned the
underlying purpose and reason for the universe’s existence and Al-khalili
professed an interest only in how it came to exist.
This is all very unsurprising, but what
frustrated me was the implication that the dispassion required for doing science
prohibits us from developing any sense of wonder or profundity for the world
because it reduces us to impartial, observers.
Why were Sacks an Al-khalili both so determined to stress that they
shared a wonder of the universe in common?
Is asking how something works
less fulfilling than asking why it
exists?
This notion that science somehow drains all
sense of wonder from the world by reducing it to a series of ‘mere facts’ seems
to demonstrate a simple inability to find those facts as interesting or
fulfilling as fictions. From the intricate creation of a human life, to the
majesty of love or the even the question of why we are here, that science
should seek to corrode any sense of awe we might have for such things is an
utter fallacy.
It is true that scientists must keep
passion and hopeful intuition in check when designing experiments and analysing
results. This all seems rather mundane if you take limited delight in data
gathering and analysis (though some would argue that they find these pursuits
positively heavenly). The careful, rigorous and objective study of reality may
well reduce it to a series of facts, but why should these facts be considered
paltry or disappointing in the face of a more supernatural understanding? Is
love really rendered boring or unsatisfying when we study oxytocin or speak of
the advantages of pair boding? Is our appreciation of the wonders of nature
really predicated upon such flimsy foundations that we can’t cope when
presented with the real facts about how they work?
Science may not give us angels, gods or the
ability to plumb hitherto untapped depths in our psyches to reveal superpowers,
but it does give us the most pragmatic and efficient tools with which to
alleviate human suffering in all of its many guises. It also provides us with a long-running
narrative about the world that is far richer in its complexity and far more
nuanced than anything religious texts or traditions can provide.
Any scientist with a modicum of interest in
the world will assert that understanding the universe with science is awe-inspiring
and provides sufficient fulfillment to be on par with the spiritual wonder of
believing in an intelligent power. Science charts the clockwork steps of the celestial
dance; watches the death throes of stars, probes into the very building blocks
of matter and guesses at the wonders yet to be discovered beyond the visible
universe. Science delves deeper, further, higher, faster and with more
precision than any other method with which we strive to understand reality. Why
must we look to religion to provide wonder for us when reality, un-augmented by stories and non-empirical appreciation,
already does a good enough job?
My final bugbears came from the meeting of
Sacks and Dawkins. Both spoke of the
virtues of encouraging children to question assumptions about the nature of the
world, whether from the perspective of the Jewish faith or from Dawkins’s
favored secular stance. Naturally
Dawkins repeated his oft-spoken assertion that indoctrinating children into any
belief-system for which there is no supporting evidence was tantamount to
abuse.
Sacks’s rejoinder was that providing children
with a strong sense of identity and heritage is important. He argued that religious
belief encourages our children to view the world within the confines of a
well-structured morality and provides them with the sense of belonging and
identity that they need to grow into well-rounded people.
However, this presumes that those children
introduced into no faith or belief system are wandering lost in a barren
wasteland of confusion and cultural isolation. It is true that children
provided with a ready-made religious understanding of the world are endowed
with parables, traditions and teachings that offer clearly defined moral
guidance and a framework with which to understand or at least appreciate the
nature of reality. Belonging to a faith, is belonging to something. Arguably, those
with no religious or strong cultural traditions to cleave to are surely all the
poorer for this deficiency.
I would argue that this is nonsense. Evolutionary biology demonstrates that there
is a deep homology between the human species and all other species on the
planet, regardless of whether they happen to be plant, animal, bacteria or
slimemold. We are related, albeit distantly, to all other forms of life on our
planet. Of course we can go further than this; Carl Sagan said that we are all
made of star stuff. The atoms in us have come from the vastness of space. We
are intricately woven into the very fabric of our reality, and the stuff of our
bodies will continue to be part of that reality long after our minds have
ceased to marvel at its wonders. Can
there really be any better or more profound heritage than this one that we all
share?
Science also tells us that there are no
significant genetic differences among human beings. The construct of ‘race’ is
simply that, a mere construct. We are not as different from one another as we
are prone to thinking. Therefore, is it not better to belong to one universal
heritage were we are all of equal value than to belong to one of many smaller
groups, in which our beliefs are partisan? Is it really preferable to strive to define
ourselves as separate from the rest of humanity for the sake of having a
stronger, more concentrated identity? Surely this sort of tribalism or in-group
vs out-group thinking is the wellspring of all sectarian violence?
I am not advocating some weird intellectual
communism or a bland existence in which culture and tradition are quashed for
the sake of uniformity. I am simply suggesting that were we all to understand
ourselves in the way science shows us to be (connected to everything and
everyone) compassion and empathy for those around us, be they human or animal
would be remarkably more intuitive and sustainable. As Darwin said, ‘there is
grandeur in this view of life’, far more so than the stories that any subset of
humanity can come up with.
Perhaps if there had been more time, these
arguments would have been raised in response to Sacks’s questions. There is nothing wrong in entertaining views
of the world that are alternative to the evidence that scientific investigation
has provided. Providing that we do not
attempt to foist our intuitive beliefs upon others, we should be free to
construct our own belief-systems if we wish to. However, for its shear utility,
accuracy, testability and assumed ignorance, science is the best tool we have
to understand our world and ourselves.
Yet science goes beyond mere understanding: the legacy left by science
has afforded us the ability to improve and enhance our lives in ways that are
far more profound than any human-lead religious movement. Science is a universal leveler and a trustworthy
guide since evidence reigns
supreme.
Yet science is certainly a dangerous tool
as well as a useful one. When used for
evil means the applications of science can yield terrible outcomes. But the onus is on us to ensure that we are
compassionate and responsible custodians of this tool. Perhaps religion reminds us of the need for such
compassion (though it does a rather poor job of regulating its own tendencies
for intolerance and destruction) but human morality is not grounded in religion
alone. We do not need organized religion
to foster widespread compassion for our fellow human beings. Compassion comes from knowing what it is to be
human and knowing what it is to be human is one of the things that science is continuing
to do best.
