This link is to the audio recording on Premier Christian Radio. I was curious to know if Mike Behe would say anything new on his recent UK tour.
In this respect I found the debate beyween Mike Behe and Michael Reiss in Scotland this week particularly enlightening. I have to say that after hearing it I was even less impressed by the argument for I.D. than I was beforehand. Ironically this was in large part because he was debating not with a secularist, but with a very sincere Christian. Thus the 'well he would say that wouldn't he' type defence would not work.
In fact Michael Reiss makes a very good case for there being no need to even go down the I.D. road, for belief in God as the creator does not require this kind of limited view. To me the whole I.D. idea seems to be counter-productive - particularly as many 'prrofs' have been proven over and over to be fundamentally flawed. Conversely the supposed arguments against Evolution can so easily be refuted.
I do hope for the future health of the Christian religion that this gimmicky I.D. idea gets consigned to history sooner rather than later. It's a silly notion that may sell books and make some people feel good about themselves, but ultimately just takes many gullible people down a dead end.

Our genome is an unmitigated mess
Interesting book review in New Scientist of which the following is an extract. Read this and tell me you still believe in an omnipotent creator...
Lesch-Nyhan syndrome causes compulsive self-mutilation. Children eat their lips or fingers, and stab their faces with sharp objects. They feel the pain, but they cannot stop themselves. Why would a loving, all-powerful creator allow anyone to be born with such an awful disease?
Lesch-Nyhan is just one of the tens of thousands of genetic disorders discovered so far. At least a tenth of people have some kind of debilitating genetic disease, and most of us will become sick at some point during our lifetime as a result of mutations that cause diseases such as cancer.
The reason? Our genome is an unmitigated mess. The replication and repair mechanisms are inadequate, making mutations commonplace. The genome is infested with parasitic DNA that often wreaks havoc. The convoluted control mechanisms are prone to error. The huge amount of junk, not just between genes but within them, wastes resources. And some crucial bits of DNA are kept in the power factories - mitochondria - where they are exposed to mutagenic byproducts. "It is downright ludicrous!" declares John Avise, an evolutionary geneticist at the University of California, Irvine.
The human genome, Avise concludes, offers no shred of comfort for those seeking evidence of a loving, all-powerful creator who had a direct hand in designing us, as not just creationists but many believers who accept evolution think was the case. If some entity did meddle with life on Earth, it either did not know what it was doing or did not care, or both.

Does God exist? - (1) The Ontological Argument
Christian apologists are fond of "proving" that God exists using logic or philosophical arguments. Are the proofs mere word games, or is there more to them? One of the oldest widely disseminated arguments is the so called "Ontological" argument. In the late 11th Century St Anselm argued that we can deduce the existence of God from the mere idea of God. Just by thinking about what God is we can deduce that He exists. St Anselm's argument was:
Over time various philosphers have exposed the flaws in this argument.
Initially Anselm's contemporary, the monk Gaunilo, objected that logically one could prove anything exists by this argument. St Anselm's response was that this argument could only be applied to God, because only He could be perfect and unique.
But it was not until Emmanual Kant in the late 18th Century that the Ontological argument appears to be have been conclusively rebutted. Kant showed that the argument wrongly assumes that existence is a property. According to St Anselm the concept "God" contains contains the idea of existence. So the statement "God does not exist is a contradiction in terms. Therefore he must exist. But Kant claimed that existence does not add anything to, or define, a concept. To say something exists merely means that some object corresponds to the concept. Existence is not the same as a concept. Therefore it is not true that "God exists" must be true.
However, this argument is still used today in various forms, and with further justifications and explanations.
In future posts I'll summarize further arguments. Next will be the "Cosmological Argument"
By definition God is greater than which none can be conceived.
God can be conceived of as just an idea, or as really existing.
It is greater to exist than not to exist.
Therefore, God must exist.

Charles Kingsley on the fossil record
I've just recalled a quote by 19th century writer Charles Kingsley, made when discussing his doubt that God made the World complete with fossils that appear to predate the Creation. He said:
I do acknowledge, however, that most Christians do not subscribe to such a literal view.
"I cannot believe that God has written on the rocks one enormous and superfluous lie"I find myself ever more perplexed by the creationist view of the World. How can they sustain their belief, when every argument they produce can so easily be refuted, and when the much simpler rational solution is so blindingly apparent? I find it scary that people can be so intent on self delusion. Of what else are they capable?

Uniformitarianism...
Yes, it really is in the dictionary. Came across it completely by accident. Guess there's a weird sort of parallel with people who apparently can open up the Bible at random and find words that seem to fit the need.
"Uniformitarianism - the concept that the earth's surface was shaped in the past by gradual processes, such as erosion, and by small sudden changes, such as earthquakes, rather than by sudden divine acts, such as Noah's flood."
Cool huh?

One way Street?
I can understand how someone who believes in a God can become a non-believer, but I’m puzzled as to how a thoughtful and well informed atheist can go the other way, and “convert” to Deism. Though I note that some Christian websites take great pleasure in showcasing people who have made this leap.
As a small child I believed in all sorts of illogical things, from a jolly fellow called Father Christmas, to the Tooth Fairy who would leave money under my pillow. Gradually as I became more aware of the rational reality of the World around me these acts of faith were discarded. Along the way I learnt why parents went along with these bizarre concepts, in their sincere and thoughtful belief that it would make our childhood more wonderful and full of joy. Understandable and maybe laudable, but no way to continue to live one's life as a fulfilled adult.
Last to go, after an immense struggle to hold onto it, was my belief in the Christian God. For months - even years - before I finally admitted it, I struggled and tortured myself to hang onto my belief, but I just could not do it. Everything around me screamed that this belief could not be upheld.
When I finally accepted my new state it was probably the most wonderfully liberating moment in my entire life. To borrow from Biblical parlance, it was as if the shackles that weighed me down were cast off, and I became intoxicated by the light of reason and the loss of fear. Suddenly the World made sense, and I could experience the joy of being, without questioning everything for otherworldly meaning, without doubting my motives, or being ashamed of any ideas that did not fit into the Christian view of the World.
Since that time my journey has been one of great excitement, and I have found inner peace that I had not thought possible. It does not matter that there is no higher being, no higher purpose to life. This World is so incredibly awe inspiring that there is no need for anything else, and the Gods worshipped by the mainstream religions appear so petty and tawdry when compared to the wonderful symmetry and rationality of an evolved Universe. Yes, there are gaps in our understanding of the natural Universe, but almost every month some new part of the jigsaw is discovered that brings us closer to a fuller understanding. As short lived and physically restrained humans there will remain some things our minds are not equipped to understand, such as the unimaginable vastness of space and of time. We will most likely, however, find better ways to explain them conceptually, and that will have to suffice.
I cannot prove the non-existence of God, any more than I can prove the non-existence of fairies, but that is insufficient reason to devote my life to belief in a God. The arguments for belief are surely so self-serving and circular that I still find it incredible that so many people can suspend belief in everything they learn about our pysical nature, and instead make a blind leap into belief in Gods who are so full of contradictions and who often exhibit signs of human frailty and imperfection. For everything around us we can find a reason that does not include a God, despite the tortuous, circular arguments put forward by the apologists, which so often are the result of selective misquotation or which exhibit basic flaws in logical reasoning. And the argument that deists too readily propose that "we are too imperfect to comprehend the workings of God" is such a cop out for any action or lack of action that cannot be explained satisfactorily in terms of innate human morality.
I intend to find someone who has made this apparent leap from non-belief to belief, to try to understand the motivation, and the truth that this person has found that I have not. I feel that there may well be a fault in me that I cannot find empathy with these people, who I have to assume are still sane and rational.
I will come back to this again…

New dinosaur discovery solves evolutionary bird puzzle
From a news report today:
"A newly discovered fossil has shed light on why a group of dinosaurs looks like birds, say scientists. Haplocheirus Sollers may not be as charismatic as T. rex or as agile as a pterodactyl but it's thought to solve a long standing puzzle. Researchers believe its short arms and large claw show how bird-like dinosaurs evolved independently of birds."
Those who promote "Intelligent Design" are keen to point to apparent gaps in fossil records, and a lack of evidence of transitional creatures. This seems to ignore the fact that new fossils are being found all the time, and each time something like this is found it fills further gaps.
By contrast, I am not aware of any new discoveries which add weight to the argument for Intelligent Design. Any suggestions?
