“Life as evolving software?” – Chaitin
In a recent post at Uncommon Descent, vjtorley links to this paper by Gregory Chaitin, and a talk by Chaitin:
Anyone have any comments? To me, his paper seems to report a rather strange evolutionary model.
Critical thinking means never having to say you’re certain.
This was originally intended as a brief reply to the comment by William J Murray but it sort of grew into something a little longer so I thought, since everyone else is doing it, I’d put it up here.
William J Murray:
I think that any fair reading of UD will show that the vast majority of pro-ID posters there, and certainly the moderators and subject contributors, are not “anti-science” at all, nor “sneer” at science; rather, they have what is IMO a legitimate concern over the anti-religious, anti-theist, pro-materialist agenda that many of those currently in positions of power in the institutions of science blatantly demonstrate.
I would agree that not all contributors to UD are anti-science but there is, nonetheless, a prominent strand of such thinking there. Many of the original posts mock the speculative excesses of evolutionary psyschology, for example, or seem to gloat over instances of where science has apparently got it wrong. Those occasions where the author of such comments has got it wrong themselves pass largely unremarked. The overall impression is of an anti-science advocacy site.
Upright BiPed’s Semiotic Argument for Design
In a post here at Uncommon Descent, Upright Biped makes what he calls his Semiotic Argument for Design, which he has been challenging me to refute for some time now, but which I have been struggling to understand. So it was good to see it summarised in one place, and I’d like to take a look at it piece by piece, and with your help, try to figure out what he’s getting at (I’m assuming he’s a he, which I don’t normally do, but I think he said something once that implied he was).
It’s a response to Larry Moran who dropped by from his Sandwalk blog to talk about onion genomes, but we don’t have to worry about onions too much, I don’t think, as UBP is making a more fundamental claim.
Honeys, I’m home!
Thanks for keeping the site warm for me 🙂
Gotta lot of threads to catch up on, by the looks of things.
Still a bit gobsmacked by the number of Christians on Uncommon Descent who seem to think that William Lane Craig’s apologia for the divine command to genocide has any merit, and it’s left me somewhat sick of heart, but reassuring that Timaeus, and some others also find it abhorrent.
The idea that any action is good if you think that God commanded it seems to me so self-evidently dangerous that I simply cannot imagine how anyone can entertain it for a moment. And that’s only one of the problems with it.
For those out of the loop, the hoohah started here:
Why I refuse to debate with William Lane Craig
I think Dawkins’ excuse rings hollow, myself, but his link to Craig’s essay on the genocide of the Canaanites made my blood run cold.
Is materialism a form of dualism? I think maybe it is.
While I tend to see materialism, or any ism really, as misguided attempts to to translate the epic poem of reality into a language of limits, the universe to an Upanishad, the unknown and unexpected cuisine of eternity into bite sized morsels of processed food by-product. Ultimately, I think isms, including materialism narrow the minds of the porters stuck with the baggage. Like a person forced to wear a hat two sizes too small, like a fundamentalist’s child taught to feel shame at the first whiff of curiosity about something potentially interesting, isms discourage freestyle boogie on the cranial dance floor. They attempt to definitively answer the important question, “Why?”*. At least, that is my general attitude. I can and occasionally do trot out tome lubricant for my neurons in order to formulate a logical support for the idea, but I just ran across a printed copy of this paper in a file folder which accidentally traveled with me this week.

Truth, free will, logic
Questions about truth, free will, logic have been raised in another thread. To help clarify the discussion, let’s separate those from the “necessary premise” discussion.
Here’s an example of the argument being raised:
True statements can only be expected to exist, and we can only expect to be able to deliberately discern them, if we assume the universe is governed by logic (necssarily rationally ordered) and if we assume for ourselves the libertarian free will causative capacity to discern them.
This seems a rather strange claim, given then many people believe that our best and most reliable true statements are those coming from science, and based on describing our world in terms physical causation. Moreover, science is often considered to provide our best examples rationality and logical reasoning.
Necessary premises
In another thread, WJM has frequently made arguments similar to this:
As I have said repeatedly, premises that support one’s arguments are only necessary if one wishes to develop a rationally coherent worldview. One is always, of course, free to believe whatever they wish – rationally justifiable or not.
Several of the other participants in the discussion have found such statements to be unsatisfying. This post is intended as a place where we might hope that WJM will fill in some of the gaps.
Empiricism vs. Rationalism
In another thread, WJM writes:
Also, when I say I must accept such a prioris in order to even hope to deliberately establish a rational worldview, that means that without such premises, reason (logic) itself breaks down into nonsense.
WJM is laying out the case for rationalism. Typically, rationalism is described as assuming innate knowledge. However, some instead assume a priori knowledge. Thanks to WJM, I now have an inkling on what might be intended by “a priori knowledge.”
The opposing philosophical position is that of empiricism, that knowledge comes through the senses. Most of those posting here (self included) seem to be empiricists, while WJM is clearly standing for some version of rationalism.
This is intended as a stub topic, to allow comments specifically addressing the rationalism vs. empiricism debate.
William Lane Craig
is on a debate tour of Britain. Apparently Polly Toynbee pulled out of debating him. I heard on Uncommon Descent that a replacement had been found. (I’d emailed WLC to volunteer myself! – but I guess it has to be Somebody.)
I’m starting this thread to house any comments about the tour and the debate.
Religion’s misguided missiles
Nearly ten years ago, on the 15th September, 2001, I read this piece in the Guardian, by Richard Dawkins.
I was a theist then, a catholic, in fact, by conversion, in my early twenties, having been baptized in the Episcopal Church of Scotland, sung at matins every Sunday until from age 8 to 11, sent to a Quaker boarding school, where I was devout, if rebellious, and became a Friend, later being confirmed at a High Church Anglican church in Devon, and finally, having married a catholic, feeling I had “come home” to the catholic church.
Leo Behe on atheism
There’s an interview with Leo Behe, son of Michael Behe, that has just been published by the Humanist and is available online. Several blogs have commented on it. Since Leo Behe discusses some of the issues that have arisen here (and were unfortunately deleted), this interview might be something we would like to discuss.
In brief, Leo Behe was raised a catholic. But he has since become an atheist.
Atheism and Theism: both statements about nature?
In the previous thread, Jet Black made the following comment in response to one of my comments:
Atheism is a statement about gods, not a statement about nature. You just seem to be making them synonyms. This is precisely the same trick that creationists and religious people often try to play; implicitly claim that a bunch of things are synonymous, reject one, and then by induction, you reject them all.

I disagree. Here’s why: Continue reading
Remainders
Ilion, a regular poster at Uncommon Descent, linked to an argument for God that he makes on his blog, here. I found it interesting because it was exactly the argument (though more succinctly expressed, I think) that kept me a theist for most of my life):
The reality of minds in a material world (thus, every human being who has ever existed) is proof that atheism is false. If atheism were indeed the truth about the nature of reality, then we would not — because we could not — exist. But we do exist. Therefore, atheism is not the truth about the nature of reality.
My position was that as every one of us (I assume) has the experience I have of being aware – being a mind – and thereby of being a unique self – there must be something unique to me, that inhabits me, that is not simply a material body, which, I assumed, could carry on perfectly well, zombie-fashion, were that essential self to go on vacation for a bit. Which made an after-life perfectly reasonable: (I knew my body would cease to function, but as my self seemed to be unarguably independent of the body it inhabited, there seemed no reason to assume that it would not continue to exist independently once that body ceased to function).

The Two Lizzies
I wrote this story a while back, and posted it on a couple of forums. But I often find I need to link to it (it was written to make a point!) so I’m reposting it here. Hoping it might generate some discussion 🙂
The Two Lizzies
Lizzie was a single mum, with a one-year daughter, Beth. Lizzie wanted to get back to her job in neuroscience – she’d left tantalizing data unanalyzed – but she loved her daughter, and wanted to give her a good start in life.
Lizzie heard about an experimental technique, whereby she could be in two places at once. Perfect! She thought. I can stay at home with Beth AND go back to work.
Lizzie made an appointment for the procedure. She was told that she would undergo a whole body scan under anaesthetic, and every atom in her body would be identified and located. Then a random half would be selected and displaced one meter to her left, making two sparse copies of Lizzie. Fresh atoms, identical to those missing from each copy would then be added, resulting in two identical Lizzies where there had once been one.

Search space
A curious couple of days for me at Uncommon Descent!
I’ve always wondered why people who are skeptical about Darwinian evolution aren’t persuaded by the power of evolutionary algorithms to find creative solutions.
There seems to me to be a deep misunderstanding of a) the nature of search space (and its structure) and b) the role a Designer plays in a GA.
The oddest objection I find is the objection that the Designer designs the fitness function. If the ID of ID is the fitness function, then ID is the environment! Because that’s the analog surely.
Which is nicely Earth Motherish, I guess.
God, or the HPoC, require …
…a paradigm where ‘explanation’ means something different than the modern usage of the term.
I wrote this in response to a question about supernatural events but I think it applies to Chalmers’ ‘Hard Problem of Consciousness‘ also:
Me: Who said I was unattached and objective? Find me a single example of a supernatural event.
Other guy: Jesus’ resurrection.
Me: Perfect example. We’ll assume that Jesus’ resurrection was a real event, witnessed by millions. A team of doctors pronounce him dead as a doorknob. He turns blue, rigor mortis sets in, and the doctors take his liver and heart for transplant patients so we know he’s as dead as they come. No tricks.
Now, the next morning, a team of scientists representing every known discipline with every possible piece of testing equipment starts monitoring the cadaver. They have EEG, MRI, CAT, mass spectrometers, chemical analysis teams, scales, x-ray machines, scopes up his ass and forced through his urethra, down his throat, in his ears and nose and around his eyes up his femoral artery, cloud chambers to measure the particle interactions, and a cop with the insta cocaine detector kit snipping bits of his hair at 2 second intervals to make sure his carcass doesn’t commit a crime. After watching the decaying flesh vigilantly all morning, suddenly the systems reanimate. Brain waves start registering, a heart regrows and starts pumping, the liver develops and the gall-bladder fills with bile. Jesus takes a breath. Witnessing the monitoring devices with a mix of awe, fascination and horror, the eyelids flicker and Jesus sits up. The cop’s test turns positive and Jesus nonchalantly waves his hand and the test turns negative.
What do you think the scientists do?
What does a theist mean by ‘God’?
Crazy little thing called God:
In ancient times, unusual physical events apparently scared the shit out of the locals, even the local philosophers. Events like lightning, earthquakes, meteors, floods and things of that nature prompted fears and speculations about the wrath of some critter, a critter much more powerful than ourselves, that suffered petty jealousy and fits of rage. The goal, assuming such a being, becomes appeasement. That is a highly rational belief. Bad things are bad. It’s worth investigating ways to avoid them. It’s probably why Richard Simmons became a celebrity.
About the penguins…
I don’t know why, but I’ve always had an affinity for penguins, and a chinstrap has been my avatar for a while at Talk Rational. I tend to parse the chinstrap as a smile!
Anyway, when I was googling for images for this blog, I came across these beautiful argumentative chinstraps, photographed by Arthur Morris. Check out his blog, Birds as Art – he has some awesome photos. It’s in the blogroll.
Atheism and moral condemnation
In another very interesting discussion on Uncommon Descent, Chris Doyle asked:
1. Why should… a miserable atheist bother with life at all?
2. How do you dissuade an atheist from free-riding?
And later, in a post on another thread:
…how can any atheist condemn Breivik in terms that can be reconciled with their worldview? If life is meaningless and we face oblivion then nothing really matters – there is no wrong or right, because there is no Good or Evil: even the purpose we forge for ourselves is an act of self-deception if the atheistic worldview is true.
I’m reposting selected portions of my original response below, because, although the conversation has continued in a lively fashion since then, Chris gave me an opportunity to think though my views on this, and I thought like to invite him, or anyone else who wants to continue the discussion, the opportunity to do so in the quieter backwaters of this blog.
