The limits of science: Derek Burke

Is there anything science can’t explain? Do we need religious explanations at all? Some say not. One approach was to look for gaps in the scientific account and say “God does this”. The current debate about creationism is full of this. But it is a perilous path. Too often a scientific explanation has been found and then the “God of the Gaps” vanishes. As a Christian, I believe that there is an ultimate purpose in trying to explain the whole of the natural world. But could science and faith both be right? We all know that science works by asking “how” questions: “How does it work?” But we also ask “why” questions: “What purpose does my life have?” This is the sort of question that religious faith claims to answer but science can’t, and never will, because science is not set up to do this. So we have two sorts of questions and two sorts of answers, which complement each other.

Historically, keeping science out has not worked, and I, as a practising Christian, have nothing to fear from inquiry. My faith, though bound into history, is not as insecure as that. I’m happy to pursue science without arbitrary boundaries. But there are certain questions that involve experiments that should not be done – for instance, any involving human torture – and that must limit certain lines of inquiry. Ethical limits to experimentation need not block trying to explain something by science, but may block ways of getting data. So we need ethics and we need values, and these come from outside science. Science is not enough.

Hi Gareth, wow an actual conversation, a rare treat! Thanks for your response too.

" It's not a trivial point to argue that the "eyewitnesses" that I previously quoted endured imprisonment and death for the faith that they were advocating."

From Buddist monks burning themselves to death in protest at the supression of their faith to Islamic terrorist blowing themselves up with 'Allah Akbar' on their lips human beings seem predisposed to die for contridictory faith in alarming numbers, when the final Cathar stronghold was taken by Catholic Crusaders in the Albigensian Crusade history reports that not one of those captures took up the offer of 'Convert or Burn' and all chose a horrific death. That fact that martyrdom became an increasing problem in the early centuries of the church long after any possible eyewitness could have still been alive tends to support the point of view that the majority weren't basing their decisions on first hand witnessing of the proported events. We're a pretty strange species when all's said and done.

" For those atheists who occasionally argue that "extraordinary claims require extraordinary evidence", surely this is exactly the sort of evidence that they seek."

I'm afraid not, you still can't use the bible to prove the bible. It's often quoted that 'Absence of evidence is not evidence of absence', and this is true but does come with caveats. Firstly, absence of evidence certainly is not evidence for presence. Secondly, we have to assess (and it is admittedly not a perfect process) how likely it is that the events claimed would have left other evidence and the simple fact is that many of the events of the bible are highly public and dramatic and should have gotten a mention elsewhere, both the Romans and Jews maintained very good histories.

We have a pretty clear picture of how the four gospels developed from an earlier lost 'Q' manuscript and we can see developement of the story, so even if we assume that they are based on a single testimony it is still a single uncorroberated story teller not four individuals. Many of the 'unique' events also appear in other, previous, myths. The virgin birth, death, three days in the tomb and resurection appear in other stories of greek and Roman gods and demigods. Mithras is said to have turned water into wine iirc. One can only assume that the laws of physics and nature were suspended on a fairly regular basis until this time, or that it is more likely that we're dealing with another ernestly recorded myth.

Even the physically possible elements of the story pose problems, the method of the census is unlike any other before or since, doesn't match any recorded method and is totally impractical. Quirinius did indeed hold a census, but after Herod's death (Herod is succeeded by his son also Herod, but the younger H is specifically identified as a different individual in the bible). The slaughter of the innocents is not mentioned contemporously anywhere outside the bible despite wiping out a generation and the passover festival in which Barabas is freed so Christ can die in his place is manufactured out of whole cloth, presumably to cast blame on the Jews. Other historical and geographical errors also abound but I think I've more than laboured the point!

I'm off now, but I'll try and log on again at some point. Have a good evening/weekend!

Oh dear.
Let us be honest here. It isn’t that science does not provide answers to why questions. It answers many of them thoroughly and meaningfully. It is simply that people do not like the answers it gives. If evidence supported a pet theology who here really thinks it would not be heralded as answering the ‘why’?
Finding the answer to a question difficult to reconcile with personal intuition and training is not the same as not being able to suggest valid answers. Nor is it true that a rough answer cannot be formulated unless we know everything. We understand the geochemical and geophysical processes of this planets formation and evolution enough to answer ‘why’ it is like it is. The same goes for our understanding of ‘why’ biodiversity is what it is in relation to plate tectonics and genetic processes. We also understand the pressures on neurological development throughout evolution and can trace the developmental pathways through the fossil record. Neuroscience gives us fascinating insights into how the brain relates to animal behaviour, and in us. Our understanding of this is now shifting from correlation (such as personality changes after strokes coinciding with brain locations) to causation (as we change the genes in animals and vary their behaviour – see oxytocin and vasopressin experiments in field voles).
We really can formulate an answer to ‘why’ we are here – right now, doing what we are doing. It is simply that people do not like the answer being genes, mutation, selection and a large amount of luck. It is disingenuous to say that there is no ‘why’ answer though, when what is meant is that you don’t like the answer that the evidence suggests. And before you scurry back to God of the Gaps and say that without answering why the universe is here we cannot know about geology and biology I will point out that you argued against that, though more importantly available physics does not suggest the two are linked and the evidence regarding randomness in mutation makes it very difficult to understand how direction and fate are inserted. You do understand the meaning of random and it’s implications don’t you? Please don’t say you are just ignoring them because you are not so insecure as to think about them.

The rest reads as if your faith is above theology as well. More secure than discoveries in science as well as realities in theology and philosophy! King of your own meaning perhaps, but let us not pretend that the evidence is with you just because you have placed your claim to nobility outside the discussion of your fellow human beings.

I am ‘insecure’ enough to listen to what is being discovered about the world, but I am not so insecure as to think it a bad thing.

OK, Derek - "Why?" Why would your god, having a perfectly good spiritual world to dance around in, need to create a separate, physical, temporal world in the first place - was he/she/it/they bored? Why, having done that, did "he" tell us a load of codswallop about how "he" had done it, and let us think that was the absolute truth until, 2500 years later, we began to find out stuff that completely contradicted the story. Why did "he" need to "send his only begotten son" to die horribly to save us from "sin" - was that the only way "he" could think of to save us from something he'd made up in the first place. And why, having presumably (if "he" created us) did he give us questioning, rational minds, which serve us very well in all other areas of our lives, and then tell us that when it came to "him" we mustn't use them.

Sorry, does this article actually have a purpose?

What a load of tosh!

Bil's picture

oops, I see Roh has already pointed that out.
It is the massive "god-shaped hole" in all religious assertions.

Bil's picture

“What purpose does my life have?” This is really bad science (almost as bad as believing the patently absurd and inherently illogical ideas of religion). You have made a massive leap in assuming there should be any purpose. Please explain to me why there should be a 'purpose', or do you have to pre-suppose a deity for that? You realy shouldn't be calling yourself a scientist when you are writing this stuff. It is very silly.

P.J.'s picture

As an aside, while it doesn't invalidate the article in and of itself I think it is indicative of the sloppy thinking involvedin it's writing that after explicitly saying that religion asks 'Why' questions Mr Burke illustrates it with a question formulated to begin 'What...'.

This entire article is very nicely demolished by Carolyn Porco's much better submission to this same series.

P.J.'s picture

"But we also ask “why” questions: “What purpose does my life have?” This is the sort of question that religious faith claims to answer"

Yes but the key word is 'claims', with no evidence to back it up religion's answers on these matter have no more standing than their God of the Gaps claims that you rightly repudiate. The moment they provide evidence to back up these assertions we're back in the domain of the scientific method.

Clearly there's evidence. Whether you come to the view that you agree with the Biblical case for Christ or not is a different matter, but to assert that the Bible advances no evidence at all is absurd. Three examples from different New Testament writers spring to mind:

"For we did not follow cleverly devised stories when we told you about the coming of our Lord Jesus Christ in power, but we were eyewitnesses of his majesty." (2 Peter 1:16)

"That which was from the beginning, which we have heard, which we have seen with our eyes, which we have looked at and our hands have touched —this we proclaim..." (1 John 1:1)

"Many have undertaken to draw up an account of the things that have been fulfilled among us, just as they were handed down to us by those who from the first were eyewitnesses and servants of the word. With this in mind, since I myself have carefully investigated everything from the beginning, I too decided to write an orderly account for you, most excellent Theophilus, so that you may know the certainty of the things you have been taught." (Luke 1:1-4)

In addition, it’s clear that the majority (although not all) of the content of the Bible takes the form of historical narrative, containing events and words relating to specific people in particular places. I suggest that it’s for individual people to consider this evidence and draw their own conclusion as to whether Jesus’ claims are true or not. But for you to assert that there is “no evidence” rather suggests that you would rather that other people take your own view than that they engage with the evidence for themselves. Personally, I prefer an evidential Christianity to your atheism of the gaps.

Then 'The Lord of the Rings' is clearly evidenced then since it says within it that Bilbo took the narration directly from Frodo and wrote it in the great red book that already contianed the tale of his own journey to battle the dragon Smaug. You can't use the bible claiming to be true as evidence that it is true. The Bible claiming to be true is not evidence that the Bile is true, that's just circular reasoning.

Niether is the incorporation of real people and places, if you really think that it is evidence that outlandish tales are true I'd suggest you stay away from that issue of Spiderman where Obama comes to New York and meets him. The 'Sharp' novels may be worth avoiding to. And Blackadder.... (ad infinitum). Of course you don't, it's just more special pleading for this particular book.

But if you prefer please read 'evidence' as "credible evidence, but please feel free to look at the subject yourself" because I'd hate to suggest that in the absence of external evidence one can dismiss tales of virgin births, resurrections (multiple though strangely unmentioned by other historical sources) , water walking and miraculous catering as far better evidence that this book might just be another book of myths, folklore and mis-remembered history rather than the divine revelation of an undetected pan dimensional superbeing.
