I first watched Star Trek when I was 16 or 17 on black and white TV. It
was innovative and evoked many of the ideals of the 1960s that people
from different races and backgrounds could form a team that would
explore the universe. Spock is one of the great Sci-Fi icons. I
particularly liked his appearance in J.J Abrams' Star Trek movie from
2009, where Spock meets a younger version of himself through a time warp,
as can only happen in Sci-Fi.
From a philosophical perspective, Star Trek projected a positive, utopian scenario of human nature - envisioning a future where humans would overcome their tendency towards conflict. But it also envisioned a belief, recently expounded by Brian Cox in the final episode of his series, The Human Universe, that humans have a destiny to go beyond their Earth-bound existence.
There is a scene in Abrams' movie that is reminiscent of a scene in my novel, Elvene, where Spock is holed up in an ice cave. Such coincidences in storytelling are not uncommon, like finding the thread of a tune in a piece of music transferred into another work, though, in this case, quite unintentional, as Elvene was written many years before Abrams' Star Trek.
The newslink below to CBSNews is a very touching tribute.

Philosophy, at its best, challenges our long held views, such that we examine them more deeply than we might otherwise consider.

Genetic engineering is not an evil conspiracy
There is a lot of hysteria about GM foods and genetic engineering in general, yet it’s a path to providing benefit to all of humankind in the same way that all the scientific endeavours of the past 2 centuries have done for anyone living in a Western society. It’s true that science and technology has also provided us with military advances that could literally destroy the planet, but the technology that drove 2 world wars in the last century also gave us accessible air travel, computers and satellite navigation and communication, albeit the last are really consequences of the Cold War.
I’ve just finished watching Brian Cox’s BBC series, The Human Universe, and, in the last programme, he extols us to value knowledge for its own sake and not just to deliver economic gains, and to raise science to an enlightenment subject in education. He doesn’t use the term ‘enlightenment’ but I do because not enough people realise how enlightening it is and has been since the time of Copernicus, Galileo and Kepler.
In a recent episode of Catalyst, they provide a mini-doco (9 mins long) on the work of Prof David Craik, which promises breakthrough developments in medicine for the whole world using genetic engineering techniques.
I’m not sure if the programme can be accessed outside Australia, but essentially Craik has worked in the area of ‘cyclotides’, which are cyclic peptides found in nature. Cyclic peptides aren’t broken down in our bodies so we can use the structure on other peptides allowing us to deliver specific ‘drugs’ to combat specific diseases. This is molecular engineering, but we can also use plants as 'factories' to create these drugs and deliver them in their seeds to third world countries (genetic engineering).
The general public is very ignorant about the role of bio-molecular science and how the world can benefit from these interventions. Instead, genetically modified crops are seen as an evil conspiracy by corporations to control the world’s food production. The truth is that humanity has been genetically modifying crops for centuries - well before Darwin’s theory of natural selection - by artificially selecting genes in both crops and domestic animals. Almost nothing we eat hasn’t been genetically modified from its natural habitat due to human intervention.
As I’ve mentioned in other posts, very few politicians are science-literate, and many see science as a servant to economic policy and nothing more. The truth is that only science can save humanity from itself. As Brian Cox reminds us (more than once) we are ‘special’ and possibly unique to the universe, in that we can appreciate the much bigger picture of the whole universe and understand our place in it. We are the only species on the planet that has the ability to transcend our origins, and, arguably, we have an obligation to pursue that, and we can only do that through science.

That Mystery of Mysteries
I read an interesting article in the latest issue of Philsophy Now (Issue 105, Nov/Dec 2014) by Toni Vogel Cary titled, That Mystery of Mysteries, about the 2 centuries old debate regarding the theory of evolution and God-manipulated speciation. Toni Vogel Carey is introduced as ‘a philosophy professor in a former life, has written for twenty years… and serves on the US advisory board of Philosophy Now.’
She presents some interesting statistics that suggest ignorance in science this century is increasing rather than decreasing. For example: ‘In Great Britain, few besides evangelicals paid attention to creationism before 2002. But by 2006, a BBC poll showed that 4 out of 10 in the UK thought religious alternatives to Darwin’s theory should be taught as science in schools.’
She then gives equally scary anecdotes for the former Eastern European block countries, where, for example: ‘In 2006, Poland’s minister for education repudiated the theory of evolution, and his deputy dismissed it as “a lie”.’
She gives other examples, from various countries and educational institutions that should ring alarm bells for anyone interested in providing scientific tuition to future generations. Towards the end of her lengthy discussion that goes back to Herschel, Lyell and Darwin (of course), she cites a recent publication by Thomas Nagel, titled Mind & Cosmos (2012) (which I haven’t read, it must be stated) where ‘Nagel argues for “natural teleology”, a view of nature as forward-looking and purposeful, yet secular rather than deistic or theistic.’ And herein lies the rub: it is very difficult for us to believe that something like us (humans) could not be the consequence of some ‘cosmic plan’ (That Mystery of Mysteries), the why and wherefore we have speculated about ever since we gained the ability to think and imagine in a way that no other species can even cognise.
At the risk of going off on a complete tangent, I wish to reference an excellent BBC doco I saw recently called Apeman – Spaceman, the first of a 5 part series, Human Universe, presented by that cross between David Attenborough and a failed rock star, Brian Cox. Cox starts his programme, in a very Attenborough-like moment, attempting to cosy up to some baboons who live in the highlands of Ethiopia. Though not our closest relative and not even true baboons, Cox explains that, amongst the higher primates, they have the most complex social behaviours, second only to humans, and can even string together a series of vocalisations, thus combining sounds that have different meanings individually.
The point of this explication is to demonstrate the humungous gap that exists between humans and all other species on the planet, cognitively. One really cannot overstate this point, as many people prefer to believe that there is nothing ‘special’ about humans at all. But as Cox states explicitly, we are ‘unique’, certainly on planet Earth and possibly in the entire universe. We are unique because we are the only species that can speculate about, let alone comprehend, our place in the much larger scheme of things. It is from this unique cognitive vantage point that both religion and science arose.
If there is any one thing that defines humanity as a species it is surely curiosity. It is curiosity that has led us into space (the focus of Cox’s first episode) but also led us on an intellectual trail uncovering such wonders as mathematical calculus, nuclear physics, the human genome and every scientific discovery since we first grasped the art of writing down our thoughts so future generations could build an unassailable cumulative knowledge that has given us computers, air travel, smart phones and all the mod-cons we take for granted in Western societies the world over.
And this exceptional evolutionary ‘success’ also creates a paradox in popular Western thinking as Carey’s discussion exposes. Whilst we all accept the benefits that science has provided for us, without even thinking about them most of the time, many of us can’t accept that science has also provided an explanation for how Earthly species have developed, changed, evolved, gained ascendency and become extinct.
I believe there are 2 reasons for this. Firstly, scientific knowledge is always contingent on future discoveries. This means we never know everything, and, what’s more, we never will. There are limits to what we can know as I’ve discussed in another post. So how do I know that evolution is true? Because the biological knowledge that underpins the human genome project (DNA) also underpins the theory of evolution, completely unknown and unforeseen in Darwin’s time. This is a well documented and carefully studied case where future discoveries enhanced a contentious scientific theory beyond its originators’ (Darwin’s and Wallace’s) wildest imaginings.
But there is still a lot we don’t know about evolution: for example, how did DNA evolve and how did it originate? Did it come from outer space? In response, creationist and ID advocates can provide glib answers that, if taken seriously, close off any further avenues of investigation; effectively stemming the very curiosity that has given us what we have learned to date.
The second reason is that our intuition and common sense can let us down when it comes to scientific knowledge. There are 2 well-known examples: Einstein’s theories of relativity and quantum mechanics. Relativity theory tells us that clocks run slower when they travel faster (relative to another clock) and clocks run faster in lower gravity (like on satellites as opposed to ground level, Earth). Intuition and common sense tell us that this can’t be true, yet the GPS in your mobile phone or in the Sat-Nav of your car depend on relativity for their accuracy.
Quantum mechanics tells us that a particle can exist in superposition with itself: an electron can go through 2 slits at once and interfere with itself on the other side, though if we try and determine which slit it goes through then it will only go through one of them. Yet quantum mechanics is not only the most empirically successful theory in the entire history of science, it underpins every electronic device you use, from TVs to computers to washing machines.
As I’ve stated many times on this blog in a variety of contexts, the biggest mystery of the universe is that it created the means to understand itself, through us. As I’ve also stated, more recently, the biggest difference between religion and science is that religion maintains the universe is teleological and science tells us that it’s not. So how do I reconcile this? Basically, I argue that ‘purpose’ has evolved, meaning there was no pre-ordained plan. It’s like God really did cast a set of dice and allowed the universe to find its own purpose. Einstein famously said, "God does not play with dice", but chaos and quantum theory suggest otherwise.
Addendum: This is a related post that I wrote a few years back, where, in the final paragraph, I come to a similar conclusion.

Ursula Le Guin's acceptance speech at the American Book Awards 2014
An acerbic commentary on the publishing industry from someone who's been in it for a long, long time; very successfully, I might add.
I've added Neil Gaiman's intro because it says so much about both of them.
I came across this by accident; posted as recently as November last year.
I'm a huge fan: Left Hand of Darkness, The Dispossessed and the Earthsea Quartet, which I re-read not that long ago. She's one of the greats: up there with Isaac Asimov, Robert Heinlein, Frank Herbert and Arthur C Clarke.

With a Little Help from my Friends (Cologne Concert)

Just a small tribute to someone who gave us something special. An inspiration and a legend.
'With a Little Help From my Friends' never fails to give me goose bumps, but on this occasion both these songs make me teary-eyed in their final moments.

Theory, knowledge and truth
Bear with me while I give a little backstory. Julia Zemiro, the effervescent host of RocKwiz (a brilliant show for those who are missing out) has made a TV series called ‘Home Delivery’ where she takes a celebrity (all comedians, either UK or Oz) back to their home town. In a recent episode she took Ruth Jones, an award-winning UK comedienne back to her home town in Wales. As part of the tour, she visited her church where a number of events in her life took place, apparently.
Given the context, Julia asked her if she was a ‘believer’. I thought Jones’ answer so candid and honest, it’s worth repeating. She said she believes there is something ‘greater than us’ but we really ‘have no idea’. Maybe not her exact words but certainly her sentiment. It was the admission of ignorance and humility that struck me – so different to any theological statement one cares to hear. And I realised, by the sheer contrast implicit in her statement, why I have such an issue with the Church; well, any church, basically. Because they all claim to know what they can’t possibly know and preach it with the absolute certainty that dogma requires.
And despite what they all claim, there is no text anywhere in the world that can tell us what, if any, greater purpose there is. Now, I’m not opposed to the idea that there could be a greater purpose and I have no problem with people believing that (like Ruth Jones). I only have a problem when they claim to know what that purpose is and what one must do (in this life) to achieve it.
When I was a philosophy student, a lecturer made the salient point that there are things one believes and things one knows and it’s important to keep in mind that what one believes should be contingent upon what one knows and not the converse. This is perfectly logical, even common sense, yet it’s extraordinary the mental gymnastics some people will perform to maintain a contrary position. To give an example, I read an account where William Lane Craig, in a conversation with the author of a Christian text, defended his belief that Mary conceived Jesus without having sex.
And this brings me to the fundamental epistemological divide that exists between science and religion, as we see it discussed and abused in the so-called Western world. Because science is essentially about knowledge, about what we know as opposed to what we might speculate and philosophise about, even though the boundaries sometimes get a bit blurred.
The success of science, over a period of 2500 years, if one wants to go back to Thales and Pythagoras, has arisen from a combination of theory, mathematics and empirical evidence. Now, whilst there is not a lot of mathematics in the biological sciences, it’s the discovery of DNA, with its inherent ‘software-like’ code that underpins all of biology and evolutionary theory in particular. And like the other disciplines of science, mathematics (in the form of knot theory) is informing us as to how DNA actually manages to function.
But out of that triumvirate, it is empirical evidence that ultimately holds sway. We can find truth in mathematics independently of any physical parameters, but when we apply our mathematics to physical theories, only physical evidence tells us if the theory is true. An example is string theory, which is a mathematical model of the universe predicting up to 11 dimensions, yet, whilst no evidence can be found to confirm it, it really does remain just a theory. Whereas Einstein’s theories of relativity (the special and general theory) are proven facts, as is quantum mechanics. Evolution, I would argue, is also a fact, simply because the evidence that proves it’s true could just as readily prove it’s wrong (the evidence is not neutral). So theories can be facts and not ‘just a theory’.
But all scientific knowledge is contingent on future knowledge which is how it has evolved. For example, Newton’s theories were overtaken by Einstein’s theories, yet the equations governing relativity theory reduce to Newton’s equations when relativistic effects are negligible. As someone once pointed out (John Worrall, London School of Economics, 1989) it’s the mathematics that survives from one physical theory to the next that informs us what aspect of the original theory was true. Again, referring to Newton and Einstein, gravity obeys an inverse square law in both their theories.
As I’ve described on another post when I reviewed Noson S. Yanofsky’s excellent book, The Outer Limits of Reason, there are limits to knowledge at all levels. So science acknowledges that it’s impossible to know everything, yet there is every reason to believe that our knowledge will increase for as long as humanity can survive. At the end of my last post, I pointed out that an implication of Godel’s Incompleteness Theorem is that mathematics is infinite, which means that there is no end to what we can discover.
So where does philosophy sit and where does religion sit amongst all this scientific knowledge? Well, I would suggest that there is an interface between science and philosophy that will always exist because philosophy quests for answers that are currently beyond our reach, some of which, like multiverses and Artificial Intelligence, may be resolved or may not.
A few years back, I said that religion is the mind’s quest to find meaning for its own existence, and I think that this is a perfectly logical and healthy thing for a mind to do. But religion, as it has evolved culturally, is full of mythology dressed up as truth. That is not to say that the figures who feature prominently in these religions are necessarily fictional, but the stories that have arisen in their wake are mythological in content. People like Jesus, Mohammed, Buddha, even Confucius, never wrote anything down so we are left with their ‘sayings’ (Mohammed was illiterate, which is why the Quran is probably in verse). But myth is very hard to shake once it takes hold in the collective consciousness of a population, and once it becomes ‘religion’ it becomes heretical to even question it.
Unfortunately, much of the debate between science and religion stems from what people think constitutes truth. Truth can exist in fiction, but in the form of life-lessons rather than narrative facts. When people believe that a narrative containing mythical elements is true, they will often argue that the mythical elements really happened by giving them supernatural attributes (like the example provided by Craig above). This is anathema to a scientifically trained mind and as far from any truth they would care to entertain.
So when people use the Bible as a criterion for scientific truth, it is certain to create conflict. Four hundred years ago, Galileo was threatened with torture by the Vatican for proposing that the Earth went round the Sun instead of the converse, as was then believed. The Vatican’s contention was that this contradicted a passage in the Bible that claims that God stopped the Sun moving in the sky. Now, we all know (thanks to pure science) that God could not have stopped the sun moving in the sky because the sun doesn’t move at all relative to the Earth’s orbit.
Yet still, in the 21st Century, we have people (like Ken Ham) claiming that the book of Genesis, which is full of mythological events like a snake that talks and a woman made from a man’s rib and a man made from dirt and a piece of fruit that turns people evil, nevertheless overrules all of modern science. I apologise on behalf of all Australia for unleashing Ken Ham onto the modern world, where he clearly doesn’t belong.
I once posted a question on his website asking for the nomination of one scientific discovery in the past 2500 years that has been made from studying the Scriptures. Not surprisingly, I never received a reply.
A few hundred years before Christ was born, Euclid, who was Librarian at the famous Library of Alexandria, wrote his seminal text, The Elements. This is arguably one of the most important texts ever written, certainly more important than any religious text as it contains real transcendental truths in the form of mathematical proofs. Mathematics is the only knowledge we have that transcends the Universe. As John Barrow quipped in one of his many books (citing Dave Rusin): Mathematics is the only part of science you could continue to do if the Universe ceased to exist.
It is hard to go past mathematics if you want truths, especially truths that are independent of humanity and the Universe itself. Of course, not everyone agrees with this Platonic sentiment, but it’s hard to avoid when one considers that there are an infinite number of primes that we can’t possibly know or an infinite string of digits in pi that we know must exist yet can’t possibly cognise. Mathematics is transcendent simply because it embraces infinity on so many levels.
To quote Barrow again, in a slightly more serious tone:
Mathematics is part of the world, and yet transcends it. It must exist before and after the Universe. Most scientists and mathematicians… work as though there were an unknown realm of truth to be discovered.
Given the context, Julia asked her if she was a ‘believer’. I thought Jones’ answer so candid and honest, it’s worth repeating. She said she believes there is something ‘greater than us’ but we really ‘have no idea’. Maybe not her exact words but certainly her sentiment.

So when people use the Bible as a criterion for scientific truth, it is certain to create conflict. Four hundred years ago, Galileo was threatened with torture by the Vatican for proposing that the Earth went round the Sun instead of the converse, as was then believed. The Vatican’s contention was that this contradicted a passage in the Bible that claims that God stopped the Sun moving in the sky. Now, we all know (thanks to pure science) that God could not have stopped the sun moving in the sky because the sun doesn’t move at all relative to the Earth’s orbit.
Yet still, in the 21st Century, we have people (like Ken Ham) claiming that the book of Genesis, which is full of mythological events like a snake that talks and a woman made from a man’s rib and a man made from dirt and a piece of fruit that turns people evil, nevertheless overrules all of modern science. I apologise on behalf of all Australia for unleashing Ken Ham onto the modern world, where he clearly doesn’t belong.
I once posted a question on his website asking for the nomination of one scientific discovery in the past 2500 years that has been made from studying the Scriptures. Not surprisingly, I never received a reply.
A few hundred years before Christ was born, Euclid, who was Librarian at the famous Library of Alexandria, wrote his seminal text, The Elements. This is arguably one of the most important texts ever written, certainly more important than any religious text as it contains real transcendental truths in the form of mathematical proofs. Mathematics is the only knowledge we have that transcends the Universe. As John Barrow quipped in one of his many books (citing Dave Rusin): Mathematics is the only part of science you could continue to do if the Universe ceased to exist.
It is hard to go past mathematics if you want truths, especially truths that are independent of humanity and the Universe itself. Of course, not everyone agrees with this Platonic sentiment, but it’s hard to avoid when one considers that there are an infinite number of primes that we can’t possibly know or an infinite string of digits in pi that we know must exist yet can’t possibly cognise. Mathematics is transcendent simply because it embraces infinity on so many levels.
To quote Barrow again, in a slightly more serious tone:
Mathematics is part of the world, and yet transcends it. It must exist before and after the Universe. Most scientists and mathematicians… work as though there were an unknown realm of truth to be discovered.
