KF vs Toronto & Petrushka

Over at UD, KF has started a new thread criticizing Toronto.  He had earlier started a thread criticizing Petrushka.

It would have been nicer if KF had joined here to launch his criticism, instead of taking pot shots from UD where it is my understanding that both Toronto and Petrushka have been banned.

In any case, this is where the two accused can set the record straight by explaining what they actually meant.  Others can join in.  I may add something later.

Let’s keep it polite.  No character attacks.  Let’s stick to clear explanations of positions that KF might have misunderstood.  And let’s remember the rules of The Skeptical Zone and keep it civil.

Open for discussion.

Science and quantification

Barry Arrington has started a new thread over at UD, where he argues that it is perfectly okay if CSI (complex specified information) cannot be quantified.

I responded, in a comment, that he seems to be making the case that CSI is not a scientific concept.  It occurred to me that folk here might want to have a discussion on what is required of a concept, for it to be part of a scientific theory.

It seems to me that, at the very least, the concept has to be defined precisely enough that one can form testable hypotheses.  Moreover, these hypotheses need to be testable by independent researchers, and the tests need to provide some kind of reliability (i.e. reasonable agreement between results obtained by independent researchers).  Perhaps that’s weaker that quantifiable.  However, I think even that weaker requirement is a problem for CSI, as it is currently “defined”.

The topic is open for discussion.

2nd Law of Thermodynamics — an argument Creationists and ID Proponents should NOT use

ID proponents and creationists should not use the 2nd Law of Thermodynamics to support ID. Appropriate for Independence Day in the USA is my declaration of independence and disavowal of 2nd Law arguments in support of ID and creation theory. Any student of statistical mechanics and thermodynamics will likely find Granville Sewell’s argument and similar arguments not consistent with textbook understanding of these subjects, and wrong on many levels. With regrets for my dissent to my colleagues (like my colleague Granville Sewell) and friends in the ID and creationist communities, I offer this essay. I do so because to avoid saying anything would be a disservice to the ID and creationist community of which I am a part.

I’ve said it before, and I’ll say it again, I don’t think Granville Sewell 2nd law arguments are correct. An author of the founding book of ID, Mystery of Life’s Origin, agrees with me:

“Strictly speaking, the earth is an open system, and thus the Second Law of Thermodynamics cannot be used to preclude a naturalistic origin of life.”

New categories and menu item

I’ve added a menu item called “Old but Active” where you can find threads that are still creating discussion but which have dropped off the front page.

I’ve also added two new categories, one for Upright Biped’s Semiotic Argument for ID and one for Granville Sewell’s (or anyone else’s) ideas about the 2nd Law of Thermodynamics.

I hope this will make things easier to find.  The search engine actually works fairly well, though.

James Barham on Mary Jane West-Eberhard and teleology

UD has featured a post by James Barham on the work of Mary Jane  West-Eberhard.  I shall be questioning Barham’s conclusions.

Unlike the subject of my previous column in this series, James A. Shapiro, she does not present her ideas as revolutionary or as a mortal threat to the Darwinian worldview.

In my opinion (as a non-biologist), she is entirely correct about that.

And yet, I shall argue that West-Eberhard—who is a researcher at the Smithsonian Tropical Research Institute in Panama, as well as a professor of biology at the University of Costa Rica—has made a foudational contribution to a new and revolutionary approach to evolutionary theorizing that bids fair (whatever her expressed intentions) to turn mainstream Darwinism on its head.

Perhaps it challenges the strawman version of Darwinism that creationists and ID proponents love to criticize.  But I don’t see it as any challenge at all to Darwinism. Continue reading

The theistic world view

There was apparently an October 2010 conference at Biola U., under the title “God & Evolution.”  Videos for some of the talks are now available, and I have listened to three of them.  The ones that I listened to were talks by Denyse O’Leary, John G. West and Jay W. Richards.

The talk by Denyse O’Leary was the first that I listened to, and it is startling.  The other two are mild by comparison.  Early in her talk, O’Leary says:

The problem with Darwinism is that it is a cultural mood.  It is not really a theory in science.  If you look at the actual science literature, what’s available to show Darwinism is negligible, piddling; the major claims are not met. Continue reading

Granville Sewell Doubles Down

As much as I hate to drive any traffic to Uncommon Descent, Granville Sewell has clarified his misunderstanding of the Second Law there recently.

Of particular note is his response to the argument that “The second law only applies to thermal entropy, and what is happening in this video does not result in a net decrease in thermal entropy, so there’s no conflict with the second law.”

In fact, it is universally recognized that the second law of thermodynamics applies to more than thermal entropy, it applies to other types of entropy, for example, the “X-entropy” associated with any other diffusing component X: as pointed out in my AML paper, these types of entropy are defined by the same equations as thermal entropy, and are equally quantifiable. And it is widely applied in physics texts to less quantifiable types of “entropy.”

I would be interested in references to the physics texts in which his concept of entropy is “widely applied” but he seems to have inadvertently disabled comments on his post. Perhaps it will provoke discussion here instead.

Apologies

Yesterday, I upgraded some plug-ins, and one of them contained an error.  As a result, yesterday member contact details were visible on the members page.  I have temporarily deleted everything on that page, and will restore it to how it was later, now that they have corrected the error.  I have now installed the correct update, and restored the page.

In future I will immediately check all visible pages after an update to prevent this happening again.  Apologies to all for not being quicker off the mark, and thanks to Rich for the tip-off.

Is Any Form Of Atheism Rationally Justifiable?

Definition of God:   First cause, prime mover, objective source of human purpose (final cause) and resulting morality, source of free will; omnipotent, omniscient and omnipresent inasmuch as principles of logic allow. I am not talking in particular about any specifically defined religious interpretation of god, such as the christian or islamic god.

Definition: Intellectual dishonesty occurs when (1)one deliberately mischaracterizes their position or view in order to avoid having to logically defend their actual views; and/or (2) when someone is arguing, or making statements against a position while remaining willfully ignorant about that position, and/or (3) when someone categorically and/or pejoratively dismisses all existent and/or potential evidence in favor of a conclusion they claim to be neutral about, whether they are familiar with that evidence or not.

Gil Dodgen on “Transparent Lunacy”

In a recent UD post, Gil has been more specific than he often is, so I thought I would respond here:

The resolution of the debate about the creative powers of natural selection is dead simple and utterly trivial to figure out.

  1. Natural selection throws stuff out. Throwing stuff out has no creative power.
  2. Existing biological information, mixed and matched, can be filtered by natural selection, as in sexual reproduction, but nothing inherently new is created.
  3. Random errors can produce survivability quotients, but only in circumstances in which overall functional degradation supports survival in a pathological environment (e.g., bacterial antibiotic resistance), and only given massive probabilistic resources and a few trivial mutational events capable of producing the survival advantage.
  4. Random errors are inherently entropic, and the more complex a functionally-integrated system becomes, the more destructive random errors become. Anyone with any experience in even the most elementary engineering enterprise knows this.

To his first, I cite this:

Cornelius Hunter vs William Dembski?

Cornelius Hunter has posted an odd argument:

Is there evidence for evolution? Sure, there is plenty of evidence for evolution. But there are significant problems with evolution. There is plenty of evidence for evolution just as there is plenty of evidence for geocentrism. But the science does not bode well for either theory.

So the evidence for evolution follows this general pattern: Even at its best, it does not prove evolution to be a fact. And furthermore, the evidence reveals substantial problems with evolution.

So how can evolutionists proclaim evolution to be a fact with such fervor? There seems to be a glaring mismatch between the evidence and the truth claims of evolutionists. The answer is that evolutionists use contrastive reasoning. Evolution is not claimed to be a fact based on how well it fits the evidence, but rather on how poorly the alternative fits the evidence. Evolution is proved by the process of elimination.

In other words, Hunter is arguing directly against Dembski:.

In eliminating chance and inferring design, specified complexity is not party to an argument from ignorance. Rather, it is underwriting an eliminative induction. Eliminative inductions argue for the truth of a proposition by actively refuting its competitors (and not, as in arguments from ignorance, by noting that the proposition has yet to be refuted)

Is purpose necessary to acquire any apparently purposeful effects?

For purposes of this discussion.

.
Chance = non-teleological causes that happen to result in particular effects via regularities referred to as “lawful” and stochastic in nature.

.
Purpose = teleological causes that are intended to result in particular effects; the organization of causes towards a pre-defined future goal.

.
My question is: can chance causes generate all of the effects normally associated with purpose,but without purpose? IOW, is purpose necessary to produce all, most, or some apparently purposeful effects, or is purpose, in effect, only an associated sensation by-product or side-effect that isn’t necessary to the generation of any particular effect normally associated with it?

The LCI and Bertrand’s Box

Tom English has recommended that we read Dembski and Marks’ paper on their Law of Conservation of Information (not to be confused with the Dembski’s previous LCI from his book No Free Lunch). Dembski also has touted the paper several times, and I too recommend it as a stark display of the the authors’ thinking.

Most people won’t take the time to carefully read a 34-page paper, but I submit that the authors’ core concept of “conservation of information” is very easily understood if we avoid equivocal and misleading terms such as information, search, and target. I’ll illustrate it with a setup borrowed from Joseph Bertrand.

The “Bertrand’s box” scenario is as follows: We’re presented with three small outwardly identical boxes, each containing two coins. One has a two silver coins, one has two gold coins, and one has a silver coin and a gold coin. We’ll call the boxes SS, GG, and SG. We are to randomly choose a box, and then randomly pull a coin from the chosen box.
