UD commenter ericB issues a Challenge!!!

I thought I would give a comment by a poster with the handle “ericB” a little more publicity as it was buried deep in an old thread where it was unlikely to be seen by passing “materialists / evolutionists”.

§§§§§§§§§§§§§§§§§§§§

Calling all evolutionists / materialists! Your help is needed! Alan Fox has not been able to answer a particular challenge, but perhaps you know an answer.

The issue is simple and the bar is purposely set low. The question is whether there exists one or more coherent scenarios for the creation of a translation system by unguided chemicals. Continue reading

Is there a Scientific Theory of Intelligent Design?

In a recent exchange at Uncommon descent I was referred by the “ineffable” Philip Cunningham (BA77) to an article at Evolution News and Views by the Discovery Institute attorney, Casey Luskin. Onward links lead me on to his Amazon review of Meyer’s “Darwin’s Doubt”. The article appears to be a response to a comment appended to the review by Nick Matzke [ETA Apparently the commenter Nick is not Nick Matzke, as Nick Matzkze points out below.]:

What’s the “scientific theory of ID”? Who or what is the designer and how can we tell? What did it do and how can we tell? How did it do it and how can we tell? Where did it do it and how can we tell? When did it do it and how can we tell?

Of herrings and miracles

Never one to turn down an opportunity for learning, I took the opportunity to read VJ Torley’s analysis of a clip of Stephen Fry on the wonderful ‘miracle of the herrings.’

Since I already know that people (even game show researchers and VJ Torley) can get facts wrong, and I am confident that most at TSZ don’t give a flying fish about the infallibility of Stephen Fry or anyone else, I’ll stick to what Torley’s article reveals regarding miracles, canonization, the Catholic Church, life, and everything.

1. The miracles performed by a candidate for sainthood don’t have to be authentic miracles.
2. One “miracle” is not sufficient to be declared a saint. Two inauthentic “miracles” are the minimum.
3. The probabilty of an erroneous witness report isn’t too high.
4. If only Hume had realised that witnesses are generally reliable, he would never had made his argument against the authenticity of miracles.
5. From 3, the probability that the testimony of a reliable witness is in error is 0.001
6. It takes 8 independent witnesses to warrant belief in a miracle.

Allowing me to conclude:

Sensory illusions are rare.
The statue of Fortuna really did speak (Plutarch’s Life of Coriolanus 37-38)
Asclepius healed thousands.
Melinda Braithwate in the fourth year (eighth grade) really would have ‘done it’ for a pound.
Darren Clowes really was eaten by wolves (also eighth grade).
Belief in many manifestations of the divine is warranted.

…I am now a Hindu.

Thanks VJ Torley!

My only confusion is as to why saints have to be attributed miracles at all, if the miracles don’t have to be real ones.

Is there an ‘Intelligent Design’ Community of Philosophers? A Response to Neil Rickert’s Hypothesis

Here is what started this conversation:

“At risk of being a bit off-topic, let me add that there is a far larger “intelligent design” community. I am talking about philosophy, particularly academic philosophy. Philosophers, as a group, tend to look at things from what I consider a[n] intelligent design perspective. That perhaps comes from Plato. Perhaps it is a natural way of thinking. To be clear, that particular intelligent design community is honest and largely non-political, unlike the religious version. And yes, there are “fine tuning” ideas coming from that community.” – Neil Rickert (http://theskepticalzone.com/wp/?p=2926&cpage=2#comment-27860)

I asked him:

“could you elaborate on this: “Philosophers, as a group, tend to look at things from what I consider a[n] intelligent design perspective”? … which philosophers, specifically who … which you suggest display a “natural way of thinking” about ‘intelligent design’?

I think I just found an even bigger eleP(T|H)ant….

I just checked out Seth Lloyd’s paper, Computational Capacity of the Universe,  and find, interestingly (although I now remember that this has been mentioned before), that his upper limit on the number of possible operations is 10^120 (i.e. 400 bits) rather than 10^150 (the more generous 500 bits usually proposed by Dembski).  However, what I also found was that his calculation was based  on the volume of the universe within the particle horizon, which he defines as:

…the boundary between the part of the universe about which we could have obtained information over the course of the history of the universe and the part about which we could not.

In other words, that 400 bit limit is only for the region of the universe observable by us, which we know pretty well for sure must be a minor fraction of the total. However, it seems that a conservative lower limit on the proportion of the entire universe that is within the particle horizon is 250, and could be as much as 10^23, so that 400 bit limit needs to be raised to at least 100,000, and possibly very much more.

Which rather knocks CSI out of the water, even if we assume that P(T|H) really does represent the entire independent random draw configuration space, and is the “relevant chance hypothesis” for life.

heh.

But I’m no cosmologist – any physicist like to weigh in?

A resolution of the ‘all-heads paradox’

There has been tremendous confusion here and at Uncommon Descent about what I’ll call the ‘all-heads paradox’.

The paradox, briefly stated:

If you flip an apparently fair coin 500 times and get all heads, you immediately become suspicious. On the other hand, if you flip an apparently fair coin 500 times and get a random-looking sequence, you don’t become suspicious. The probability of getting all heads is identical to the probability of getting that random-looking sequence, so why are you suspicious in one case but not the other?

In this post I explain how I resolve the paradox. Lizzie makes a similar argument in her post Getting from Fisher to Bayes, but there are some differences, so keep reading.

Getting from Fisher to Bayes

(slightly edited version of a comment I made at UD)

Barry Arrington has  a rather extraordinary thread at UD right now, ar

Jerad’s DDS Causes Him to Succumb to “Miller’s Mendacity” and Other Errors

It arose from a Sal’s post, here at TSZ, Siding with Mathgrrl on a point,and offering an alternative to CSI v2.0

Below is what I posted in the UD thread.

Siding with Mathgrrl on a point,and offering an alternative to CSI v2.0

[cross posted from UD Siding with Mathgrrl on a point, and offering an alternative to CSI v2.0, special thanks to Dr. Liddle for her generous invitation to cross post]

There are two versions of the metric for Bill Dembski’s CSI. One version can be traced to his book No Free Lunch published in 2002. Let us call that “CSI v1.0”.

Then in 2005 Bill published Specification the Pattern that Signifies Intelligence where he includes the identifier “v1.22”, but perhaps it would be better to call the concepts in that paper CSI v2.0 since, like windows 8, it has some radical differences from its predecessor and will come up with different results. Some end users of the concept of CSI prefer CSI v1.0 over v2.0.

VJ Torley on Order versus Complexity

VJ has written, by his standards, a short post distinguishing order from complexity (a mere 1400 words). To sum it up – a pattern has order if it can be generated from a few simple principles. It has complexity if it can’t.  There are some well known problems with this – one of which being that it is not possible to prove that a given pattern cannot be generated from a few simple principles.  However, I don’t dispute the distinction. The curious thing is that Dembski defines specification in terms of a pattern that can  generated from a few simple principles. So no pattern can be both complex in VJ’s sense and specified in Dembski’s sense.

At the heart of this the problem is that Dembski has written a paper that most IDers would find unacceptable if they took the trouble to understand it.  But they don’t quite have the courage to say they disagree. That is why this comment from  Eric Anderson made me chuckle:

Second, why is it so hard for some people to get it through their heads that the issue is not “order”? Is this really hard to understand, or just that so many people haven’t been properly educated about the issues?

I wonder which one it is in William Dembski’s case?

Appendix

TJ has written a 4000 word appendix to this post. I haven’t time to read it all but it appears that he accepts that some of his original OP was wrong. It is rare for people to admit they are wrong in heated Internet debates so all credit to him. In particular he appears to accept that there is considerable confusion about order, complexity, and specification within the ID community (why else the need to propose his own definitions?).

What would be really nice would a similar admission from Eric Anderson that the ID community needs to sort out its own definitions before complaining that others are incapable of understanding them.

The eleP(T|H)ant in the room

The pattern that signifies Intelligence?

Winston Ewert has a post at Evolution News & Views that directly responds to my post here, A CSI Challenge which is nice. Dialogue is good.  Dialogue in a forum where we can both post would be even better.  He is extremely welcome to join us here 🙂

 

In my Challenge, I presented a grey-scale photograph of an unknown item, and invited people to calculate its CSI.  My intent, contrary to Ewert’s assumption, was not:

…to force an admission that such a calculation is impossible or to produce a false positive, detecting design where none was present.

but to reveal the problems inherent in such a calculation, and, in particular, the problem of computing the probability distribution of the data under the null hypothesis: The eleP(T|H)ant in the room

The Laws of Thought

aren’t.

They are perfectly valid rules of reasoning, of course.  Wikipedia cites Aristotle: :

  • The law of identity: “that every thing is the same with itself and different from another”: A is A and not ~A.
  • The Law of Non-contradiction: that “one cannot say of something that it is and that it is not in the same respect and at the same time”
  • Law of Excluded Middle: “But on the other hand there cannot be an intermediate between contradictories, but of one subject we must either affirm or deny any one predicate.”

And of course they work just fine for binary, true-or-false, statements, which is why Boolean logic is so powerful.

But I suggest they are not Laws of Thought.

Specification for Dummies

I’m lookin’ at you, IDers 😉

Dembski’s paper: Specification: The Pattern That Specifies Complexity gives a clear definition of CSI.

The complexity of pattern (any pattern) is defined in terms of Shannon Complexity.  This is pretty easy to calculate, as it is merely the probability of getting this particular pattern if you were to randomly draw each piece of the pattern from a jumbled bag of pieces, where the bag contains pieces in the same proportion as your pattern, and stick them together any old where.  Let’s say all our patterns are 2×2 arrangements of black or white pixels. Clearly if the pattern consists of just four black or white pixels, two black and two white* , there are only 16 patterns we can make:

Patterns1And we can calculate this by saying: for each pixel we have 2 choices, black or white, so the total number of possible patterns is 2*2*2*2, i.e 24  i.e. 16. That means that if we just made patterns at random we’d have a 1/16 chance of getting any one particular pattern, which in decimals is .0625, or 6.25%.  We could also be fancy and express that as the negative log 2 of .625, which would be 4 bits.  But it all means the same thing.  The neat thing about logs is that you can add them, and get the answer you would have got if you’d multipled the unlogged numbers.  And as the negative log of .5 is 1, each pixel, for which we have a 50% chance of being black or white, is worth “1 bit”, and four pixels will be worth 4 bits.

Protein Space and Hoyle’s Fallacy – a response to vjtorley

‘vjtorley’ has honoured me with my very own OP at Uncommon Descent in response to my piece on Protein Space. I cannot, of course, respond over there (being so darned uncivil and all!), so I will put my response in this here bottle and hope that a favourable wind will drive it to vjt’s shores. It’s a bit long (and I’m sure not any the better for it…but I’m responding to vjt and his several sources … ! ;)).


“Build me a protein – no guidance allowed!”

The title is an apparent demand for a ‘proof of concept’, but it is beyond intelligence too at the moment, despite a working system we can reverse engineer (a luxury not available to Ye Olde Designer). Of course I haven’t solved the problem, which is why I haven’t dusted off a space on my piano for that Nobel Prize. But endless repetition of Hoyle’s Fallacy from multiple sources does not stop it being a fallacious argument.

Dr Torley bookends his post with a bit of misdirection. We get pictures of, respectively, a modern protein and a modern ribozyme. It has never been disputed that modern proteins and ribozymes are complex, and almost certainly not achievable in a single step. But

1) Is modern complexity relevant to abiogenesis?

2) Is modern complexity relevant to evolution?

Prizegiving!

Phinehas and Kairosfocus share second prize for my CSI challenge: yes, it is indeed “Ash on Ice” – it’s a Google Earth image of Skeiðarárjökull Glacier.

But of course the challenge was not to identify the picture, but to calculate its CSI. Vjtorley deserves, I think, first prize, not for calculating it, but for making so clear why we cannot calculate CSI for a pattern unless we can calculate “p(T|H)” for all possible “chance” (where “chance” means “non-design”) hypotheses.

In other words, unless we know, in advance, how likely we are to observe the candidate pattern, given non-chance, we cannot infer Design using CSI. Which is, by the Rules of Right Reason, the same as saying that in order to infer Design using CSI, we must first  calculate how likely our candidate pattern is under all possible non-Design hypotheses.

As Dr Torley rightly says:

Professor Felsenstein is quite correct in claiming that “CSI is not … something you could assess independently of knowing the processes that produced the pattern.”

And also, of course, in observing that Dembski acknowledges this in his paper, , Specification: The Pattern That Signifies Intelligence, as many of us have pointed out.  Which is why we keep saying that it can’t be calculated – you have to be able to quantify p(T|H), where H is the actual non-design hypothesis, not some random-independent-draw hypothesis.

DonaldM, at UD, asks…

…an odd, but revelatory, set of questions:

1. How do you know scientifically (and I emphasize “scientifically” here because I want to make it clear that theological, metaphysical or philosophical opinions – while important for other reasons – have no bearing on the question at hand) that the properties of the Cosmos are such that any apparent design we observe in natural systems can not be actual design, even in principle?

I don’t.

2. How do you know scientifically that Nature (or the Cosmos) is a completely closed system of natural cause and effect? (Recall Dawkins claim that a universe superintended by a Deity would look much different than ours as he says in The God Delusion several times)

I don’t.

3. How do you know scientifically that the properties of biological systems are such that any apparent design we observe in them can not be actual design, even in principle? (The Blind Watchmaker and Dawkins’s claim that “Biology is the study of complicated things that give the appearance [emphasis mine] of having been designed for a purpose.”)

I don’t.

4. How do you know scientifically that no supernatural being, if such actually existed, could ever take any action within nature itself that would produce observable phenomenon or effect any change in the arrangement of matter or energy anywhere in the Cosmos?

I don’t.

Does anyone here?  And does any one make any such claims?  I don’t.

Is Darwinism a better explanation of life than Intelligent Design?

I recently bumped a post by keiths: Things That IDers Don’t Understand, Part 1 — Intelligent Design is not compatible with the evidence for common descent as it had come up in a recent discussion.  Vjtorley has responded on UD with a post called Is Darwinism a better explanation of life than Intelligent Design?

I’ve unbumped keiths’ post, as the thread was getting rather long, and in any case, it would be good to respond to vjtorley, who is, of course, very welcome to come over here in purpose.  I like Dr Torley, and do hope he will drop by, but in any case, the loudhailer seems to work reasonably well!

Feel free to continue the discussion that had been renewed on keiths’ post in this one (or on the old one if you like, using the link).
