Outside the System?

I recently came across this post on the BBC website, discussing the influence of human hunting activity on evolution. The basic point of the article is that humans have evolved/developed predatory abilities which are far beyond those of any other organism on the planet, and that as such we represent a major threat to the rest of the system.

Normally - so the theory goes - organisms develop, in part at least, as a consequence of an evolutionary arms race between prey and predator. So carnivores for example, become faster runners or develop sharper teeth and claws, while the herbivores they prey on become faster or larger or develop tougher skin or other defences.

The problem is that humans have an incredible ability to out-think their prey, and to develop tools or technology that can get round any or all of their defences, and they have been able to do this so quickly that evolution no longer has any chance of keeping up. The consequences of this are obvious - we have already wiped out many species and seem to be well on our way to wiping out an awful lot more!

All of this raises the question though: If evolution has been such a wonderful system up until now, then what has gone wrong? This system has worked effectively for billions of years, allegedly producing living organisms from non-organic matter and then producing the mind-blowing quantities and variety of flora and fauna that we see today. Has this system finally broken in the last couple of hundred thousand years? Has it finally unbalanced itself by producing this strange new species of super-predator which somehow seems to have the capacity to destroy the whole thing?

There is another way to read this story. It's not a scientifically precise or complete way of looking at it, but in many ways it's a lot more useful. This version of the story has been around a lot longer than modern science or evolutionary theory and can be found - yes alright, you've guessed it! - in the pages of the Bible.

This version of the story says that human beings were made, "in God's image". In ancient times, long before the advent of modern communication, if a king ruled over a large empire it was common for him to put statues of himself in the places he ruled over, to remind the inhabitants of who was in charge. In the same way, according to the Bible, God has left a living statue of himself on this planet - that is, you and me! According to the Bible then, it isn't an accident that human beings have intellectual and other capacities which are far beyond those of any other creature - we've been given these capacities by God because we are here with a job to do. We've been given control of this planet and He expects us to look after it for Him, and to show the world what He is like by our wise and careful stewardship of it.

Of course it doesn't take a genius to notice that this arrangement also seems to have gone rather wrong! But the problem is with us. We know that we have the capacity to be wise and careful stewards, but we often choose to be selfish and short-sighted instead. This again, is either a sign that evolution has gone very wrong (if you believe that version of the story), or that there are other forces beyond mere evolution which are at play.

So then, are we independent creatures with the capacity for moral choice who are meant to reflect the good God who made us, but often don't and - it seems - have become estranged from Him in some way? Or are we simply evolved beings whose existence represents the fact that the impersonal system that created us has now finally over-reached itself? Or could there - possibly - be elements of truth in both versions of this story...? What do you think...?

The lamentable state of Christian apologetics

For any readers who are unfamiliar with the term, "apologetics" (according to Dictionary.com) is "the branch of theology concerned with the defense or proof of Christianity".

In the western world at the moment, Christianity is under sustained intellectual attack, and I'm not sure we're doing a great job of defending ourselves. Many Christians learn about apologetics on theological courses, training schemes, and perhaps even through their local churches, but I think perhaps part of the problem is that we're often more concerned about bolstering our own intellectual confidence than in actually tackling the really difficult questions. It seems to me that Christians are often fed standard answers to difficult questions but are not really encouraged to think! It's much more comforting to feel as though you know the answer to something, than to ask, "But hang on a minute - does that really work? What might be the problems with that?" Then, when Christians who have been trained in this way come into contact with intelligent and well-read atheists who are more than happy to think like this, we suddenly find we're unprepared and out of our depth.

Part of the problem is in the perceived conflict between faith and scepticism. The sceptical mind will always ask, "but what about this?", whereas faith wants to believe, wholeheartedly and without question. Christians somehow need to have both. It's about being willing - even determined - to ask questions, accepting that you don't understand everything, and yet believing anyway - based on what you do know.

It is possible to be completely convinced of the truth of something, and yet be uncertain about many of the details - perhaps even many of the fundamentals. For example, the theory of evolution: 150 years ago, Darwin was convinced that life on earth had evolved through a process of evolution by natural selection and yet there were huge gaps in his knowledge and his theories which are still being uncovered today. Even now enough gaps remain to cause some scientists1 to question whether natural selection is sufficient, where others seem more than happy to stake their reputations on it.

Christians - especially Christian apologists - need to be honest, especially with themselves, about what they don't understand, and be willing to ask questions that will show up more gaps in their knowledge, rather than ones that will make them feel more confident. In my opinion, any apologist worth her salt should have a whole list of questions she can't answer - if she hasn't, then she hasn't been asking enough questions!


1. e.g. Colin Patterson, palaeontologist at the Natural History Museum, who wrote in his updated textbook on the subject, just before he died in 1998, "I am no longer certain that natural selection is the complete explanation, and I hope the new edition contains enough information ... for readers to understand the problem and judge the answer for themselves". (Note: Patterson believed wholeheartedly in evolution, he just wasn't convinced that natural selection alone was a sufficient explanation for it).

A Modern Creation Myth

No-one knows for sure exactly how the world started, since none of us were there to see it.

The Biblical creation account in Genesis is, in my view, a God-inspired myth.  It's a story, set within the cosmos according to the way the Jews understood it at the time, which attempts to encapsulate what they knew about God, the world He created, and our place within that world.

Nowadays, modern science has uncovered a lot more about the way the world works and has advanced various theories regarding it's history.  None of these theories are complete and what we think we know is constantly being challenged and refined.

Here is a modern "creation myth" based on the generally accepted current understanding.  (I prefer to think of it as supplementing, rather than replacing the original).  I found it in Arthur Peacocke's "Paths from Science Towards God":

There was God. And God was All-That-Was. God's Love over-flowed and God said, 'Let Other be. And let it have the capacity to become what it might be, making it make itself - and let it explore its potentialities.'

And there was Other in God, a field of energy, vibrating energy - but no matter, space, time or form. Obeying its given laws and with one intensely hot surge of energy - a hot big bang - this Other exploded as the Universe from a point twelve or so billion years go in our time, thereby making space.

Vibrating fundamental particles appeared, expanded and expanded, and cooled into clouds of gas, bathed in radiant light. Still the universe went on expanding and condensing into swirling whirlpools of matter and light - a billion galaxies.


Five billion years ago, one star in one galaxy - our Sun - became surrounded by matter as planets.  One of them was our Earth.  On Earth, the assembly of atoms and the temperature became just right to allow water and solid rock to form.  Continents and mountains grew and in some deep wet crevice, or pool, or deep in the sea, just over three billion years ago, some molecules became large and complex enough to make copies of themselves and became the first specks of life.

Life multiplied in the seas, diversifying and becoming more and more complex.  Five hundred million years ago, creatures with solid skeletons - the vertebrates - appeared.  Algae in the sea and green plants on land changed the atmosphere by making oxygen.  Then three hundred million years ago, certain fish learned to crawl from the sea and live on the edge of land, breathing that oxygen from the air.

Now life burst into many forms - reptiles, mammals (and dinosaurs) on land - reptiles and birds in the air.  Over millions of years the mammals developed complex brains that enabled them to learn.  Among these were creatures who lived in trees.  From these our first ancestors derived and then, only forty thousand years ago, the first men and women appeared.  They began to know about themselves and what they were doing - they were not only conscious but self-conscious.  The first word, the first laugh were heard.  The first paintings were made.  The first sense of a destiny beyond - with the first signs of hope, for these people buried their dead with ritual. The first prayers were made to the One who made All-That-Is and All-That-Is-Becoming - the first experiences of goodness, beauty and truth - but also of their opposites, for human beings were free.

The Fear of Science

A few days ago I caught part of this programme on Channel 4: http://www.channel4.com/programmes/genius-of-britain/episode-guide/series-1/episode-5

Near the end they showed a two-way interview between Richard Dawkins and Stephen Hawking.  During the interview, Hawking asked Dawkins why he was “so obsessed with God”, which I found quite amusing! I was also interested though, to hear Dawkins’ response. Dawkins said (paraphrased – I can’t remember his exact words) that science was all about asking questions and trying to understand things and he felt that belief in God got in the way of this because it encouraged people to use God as an explanation for anything they couldn’t understand.

To be honest I think this is a bit weak as many Christians are also scientists and this doesn’t appear to stop them from doing what they do.  In fact, the belief in an ordered world, which stemmed from a belief in a God of order, underpinned much early scientific research.  I do often wonder though, whether for many people, religious belief does sometimes present a barrier to honest scientific enquiry. I certainly think this is the case for many Creationists (in the narrowest sense of that word). It seems to me that hard-line Creationists have a very strong pre-defined view of what the world should be like, so that any “science” they employ is bent entirely towards proving this picture, rather than towards investigating what’s actually out there with an open mind.

On the flip side however, I think Dawkins actually does something very similar with his hard-line approach towards natural selection. He’s been quoted many times for saying that Darwin made it possible for him to be an “intellectually fulfilled atheist”. Dawkins doesn’t like mystery – he doesn’t like the unexplainable – and he believes that natural selection is able to explain everything about how the biological world – including humans – came to be the way that it is. But although most scientists (excluding Creationists) now accept that evolution has happened, there is no universal agreement on whether natural selection is the sole cause. Many (if not most) scientists would be happy to accept that there is still a significant amount of “mystery” around our understanding of what exactly has taken place.

For some Christians though, there can be a significant amount of fear involved in uncovering this mystery. What if we do manage to understand everything? Where would this leave God? If God is in the gaps in our understanding, where does He go if the gaps disappear? What if the things we discover disprove everything we thought we knew about the world?

First of all I think it’s extremely arrogant to assume that we will ever know or understand everything. For every answer we find there are - and always will be - a lot more questions. And if God is real, as Christians believe, then the mind of God will always be beyond ordinary human investigation.

Secondly though, what if the things that we discover disprove what we thought we knew? Well then, we should take it like men (or women)! Christians should have nothing to fear from the truth – it’s the foundation of our religion! If the truth we discover isn’t quite what we thought it was then obviously we have some learning to do! If God is real then we have nothing to fear from discovering His Universe. We should always be prepared to be surprised by God – and also by the truth!
