We are all waiting for the ultimate book on Intelligent Design, written by R. Marks and W. Dembski. Instead we get a “textbook”, another attempt to explain the concepts to laymen. I got the impression that the authors used this setting to avoid the necessary rigour: they just do not define terms like “search” which they use hundreds of times. This allows for a lot of hand-waving, like the following sentence on p. 174:
“We note, however, the choice of an algorithm along with its parameters and initialization imposes a probability distribution over the search space”
That unsubstantiated claim is essential for their following proofs on “The Search for a Search”!
And then there are details like this one:
p. 130: “For the Cracker Barrel puzzle [we got] an endogenous information of I = 7.15 bits”
p. 138: “We return now to the Cracker Barrel puzzle. We showed that the endogenous information […] is I = 7.4 bits”
I tried to solve this conundrum, but I came up with I = 7.8 bits. I contacted the authors, but got no reply.
I gave it a generous two stars. By chance, I looked up my link to my comment today, but I could not find my review – though it was up there for at least a couple of months. Does anyone know what has happened? Surely, The Three Doctores would not steep so low to eliminate unwanted critique!
The original mission of TSZ, as intended by the U.K.’s Dr. Elizabeth Liddle, who promoted the site to apostate peers & ‘skeptics,’ often at anti-religious online forums, lists & discussion boards, has passed its due date. She & they (many of the early people who joined) shared the experience in common of being ‘expelled’ (banned) from the IDist blog Uncommon Descent (UD) & to have their own sandbox to critique UD was the main mission of TSZ. There was no ‘inspirational’ core that Liddle offered upon departure from her own site, but returning to it in November to talk mainly about UD again could only be a fool’s errand.
My argument here is that UD is by now pretty much outdated. UD is generally seen as oddball &/or gutter-level IDist discussion, far adrift from serious conversation on the topic. It is shrinking in relevance now year on year. It thus isn’t really worth ‘reporting’ on or ‘opposing’ UD at TSZ anymore, though that IDist site was the early focus of TSZ & what brought many (most) of the early participants together. Is UD really worth time for ‘skeptics’ nowadays?
More importantly, the new blog Peaceful Science (PS) has recently surpassed BioLogos in terms of daily & hourly regular traffic & far outreaches the topics that UD used to breach. It has actual scientists, elderly or retired ‘science & religion/worldview’ people who contribute often a LOT, woolly protestants & ‘unitarian’ (or maybe just one who posts as much as 5 people), pedantic ‘natural theologians’, & S. Joshua Swamidass actually just called one person a ‘prophet’ as a welcome greeting. PS even ‘welcomes’ atheists (Swamidass has made it a point to defend Freedom From Religion Foundation proponent who is a self-described ‘militant atheist’ against multiple Christians) & agnostics & patiently fields all legitimate ‘scientific’ questions. Are you skeptical of ‘Peaceful Science’ and a ‘Science of Adam’ as proclaimed by quasi-creationists, ideology-starved geneticists & fence-sitting ‘reformers’?
Search is a central term in the work of Dr. Dr. William Dembski jr, Dr. Winston Ewert, and Dr. Robert Marks II (DEM): it appears in the title of a couple of papers written by at least two of the authors, and it is mentioned hundreds of times in their textbook “Introduction to Evolutionary Informatics“. Strangely – and in difference from the other central term information, it is not defined in this textbook, and neither is search problem or search algorithm. Luckily, dozens of examples of searches are given. I took a closer look to find out what DEM see as the search problem in the “Introduction to Evolutionary Informatics” and how their model differs from those used by other mathematicians and scientists.

Yesterday, I looked again through “Introduction to Evolutionary Informatics”, when I spotted the Cracker Barrel puzzle in section 18.104.22.168 Endogenous information of the Cracker Barrel puzzle (p. 128). The rules of this variant of a triangular peg-solitaire are described in the text (or can be found at wikipedia’s article on the subject).
The humble authors1 then describe a simulation of the game to calculate how probable it is to solve the puzzle using moves at random: Continue reading →
But some of us have bought (or borrowed) the book nevertheless. As Denyse O’Leary said: It is surprisingly easy to read. I suppose she is right, as long as you do not try to follow their conclusions, but accept it as Gospel truth.
Dembski, Marks, and Ewert will never explain how their work applies to models of evolution. But why not create at list of things which are problematic (or at least strange) with the book itself? Here is a start (partly copied from UD): Continue reading →
