The Inevitability of Life and Consciousness

Kantian Naturalist brought up the subjects of autopoesis and organizational closure whereby biological systems maintain a distinctive form while being thermodynamically open. Not only do they achieve a low entropy state but they maintain it over time.

From Wikipedia:

Autopoietic systems are “structurally coupled” with their medium, embedded in a dynamic of changes that can be recalled as sensory-motor coupling. This continuous dynamic is considered as a rudimentary form of knowledge or cognition and can be observed throughout life-forms.

 

This is not yet the inner conscious awareness possessed by higher animals but it is a step in that direction. Continue reading

Behe and Co. in Canada

This past Friday, I bumped into Dr. Michael Behe, and again on Saturday, along with Drs. Brian Miller (DI), Research Coordinator CSC, and Robert Larmer (UNB), currently President of the Canadian Society of (Evangelical) Christian Philosophers. Venue: local apologetics conference (https://www.diganddelve.ca/). The topic of the event “Science vs. Atheism: Is Modern Science Making Atheism Improbable?” makes it relevant here at TSZ, where there are more atheists & agnostics among ‘skeptics’ than average.

On the positive side, I would encourage folks who visit this site to go to such events for learning/teaching purposes. Whether for the ID speakers or not; good conversations are available among people honestly wrestling with and questioning the relationship between science, philosophy and theology/worldview, including on issues related to evolution, creation, and intelligence in the universe or on Earth. Don’t go to such events expecting miracles for your personal worldview in conversation with others, credibility in scientific publications or in the classroom, if you are using ‘science’ as a worldview weapon against ‘religion’ or ‘theology’. That argument just won’t fly anymore and the Discovery Institute, to their credit, has played a role, of whatever size may still be difficult to tell, in making this shift happen.

A question arises: what would be the first question you would ask or thing you would say to Michael Behe if you bumped into him on the street?

Self-Assembly of Nano-Machines: No Intelligence Required?

In my research, I have recently come across the self-assembling proteins and molecular machines called nano-machines one of them being the bacterial flagellum…

Have you ever wondered what mechanism is involved in the self-assembly process?

I’m not even going to ask the question how the self-assembly process has supposedly evolved, because it would be offensive to engineers who struggle to design assembly lines that require the assembly, operation and supervision of intelligence… So far engineers can’t even dream of designing self-assembling machines…But when they do accomplish that one day, it will be used as proof that random, natural processes could have done too…in life systems.. lol

If you don’t know what I’m talking about, just watch this video:

Max’s Demon, a Design Detection Riddle

Suppose Max comes to you with a sealed but clear container consisting of two separate chambers with two visible certified thermometers mounted on the sides of the two chambers. Thermometer one reads 100 degrees and Thermometer 2 reads 10 degrees. Max tells you that the temperature differential you see is the result of tiny invisible demon that controls a microscopic door between the two chambers. As individual gas molecules approach the door, the demon quickly opens and shuts the door so that only fast molecules are passed into chamber one, while only slow molecules are passed into chamber two.

Your mission if you choose to accept it is to devise a way to objectively verify the demon’s design influence on the contents of the container?

As always when it comes to riddles like this there are few ground rules.

1) you may examine the container and it’s contents in any way you like as long as you don’t violate it’s physical integrity because that will let the demon escape and ruin the closed nature of the system.

2) The demon is invisible so efforts to view him directly won’t work

3) You may examine the thermometers to verify that they are functioning correctly or replace them with ones of your choosing if you like.

I don’t want to spoil the fun by sharing my proposed method for detecting the demon’s design until I hear some of your ideas.

What do you say is objective design detection possible in this case?

Dice Entropy – A Programming Challenge

Given the importance of information theory to some intelligent design arguments I thought it might be nice to have a toolkit of some basic functions related to the sorts of calculations associated with information theory, regardless of which side of the debate one is on.

What would those functions consist of?

In Slight Defense of Granville Sewell: A. Lehninger, Larry Moran, L. Boltzmann

The basic biochemistry textbook I study from is Lehninger Prinicples of Biochemistry. It’s a well regarded college textbook. But there’s a minor problem regarding the book’s Granville-Sewell-like description of entropy:

The randomness or disorder of the components of a chemical system is expressed as entropy,

Gag!

And from the textbook written by our very own Larry Moran:

Boltzmann Brains and evolution

In the “Elon Musk” discussion, in the midst of a whole lotta epistemology goin’ on, commenter BruceS referred to the concept of a “Boltzmann Brain” and suggested that Boltzmann didn’t know about evolution. (In fact Boltzmann did know about evolution and thought Darwin’s work was hugely important). The Boltzmann Brain is a thought experiment about a conscious brain arising in a thermodynamic system which is at equilibrium. Such a thing is interesting but vastly improbable.

BruceS explained that he was thinking of a reddit post where the commenter invoked evolution to explain why we don’t need extremely improbable events to explain the existence of our brains (the comment will be found here).

What needs to be added is that all that does not happen in an isolated system at thermodynamic equilibrium, or at least it has a fantastically low probability of happening there.  The earth-sun system is not at thermodynamic equilibrium.  Energy is flowing outwards from the sun, at high temperature, some is hitting the earth, and some is taken up by plants and then some by animals, at lower temperatures.

Organisms and Machines

In the “The Disunity of Reason” thread, Mung suggested that “the typical non-theist will insist that organisms are machines, including humans.” And there is a long tradition of mechanistic metaphysics in Western anti-theism (La Mettrie is probably the most well-known example). However, I pointed that I disagree with the claim that organisms are machines. I’m reposting my thoughts from there for our continued conversation.

A machine is a system with components or parts that can be partially isolated from the rest of the system and made to vary independently of the system in which they are embedded, but which has no causal loops that allow it to minimize the entropy produced by the system. It will generate as much or as little heat as it is designed to do, and will accumulate heat until the materials lose the properties necessary for implementing their specific functions. In other words, machines can break.

What makes organisms qualitatively different from machines is that organisms are self-regulating, far-from-equilibrium thermodynamic systems. Whereas machines are nearly always in thermodynamic equilibrium with the surrounding system, organisms are nearly always far from thermodynamic equilibrium — and they stay there. An organism at thermodynamic equilibrium with its environment is, pretty much by definition, dead.

The difference, then, is that machines require some agent to manipulate them in order to push them away from thermodynamic equilibrium. Organisms temporarily sustain themselves at far-from-equilibrium attractors in phase space — though entropy catches up with all of us in the end.

It is true that some parts of an organism can break — a bone, for example. But I worry that to produce a concept general enough that both breaking and dying are subsumed under it, one can lost sight of the specific difference that one is trying to explain.

Indeed, that’s the exact problem with Intelligent Design theory — the ID theorist says, “organisms and machines are exactly the same, except for all the differences”. Which is why the ID theorist then concludes that organisms are just really special machines — the kind of machines that only a supremely intelligent being could have made. As Fuller nicely puts it, according to ID “biology is divine technology”.

What is obvious to Granville Sewell

Granville Sewell, who needs no introduction here, is at it again. In a post at Uncommon Descent he imagines a case where a mathematician finds that looking at his problem from a different angle shows that his theorem must be wrong. Then he imagines talking to a biologist who thinks that an Intelligent Design argument is wrong. He then says to the biologist:

“So you believe that four fundamental, unintelligent forces of physics alone can rearrange the fundamental particles of physics into Apple iPhones and nuclear power plants?” I asked. “Well, I guess so, what’s your point?” he replied. “When you look at things from that point of view, it’s pretty obvious there must be an error somewhere in your theory, don’t you think?” I said.

As he usually does, Sewell seems to have forgotten to turn comments on for his post at UD. Is it “obvious” that life cannot originate? That it cannot evolve descendants, some of which are intelligent? That these descendants cannot then build Apple iPhones and nuclear power plants?

As long as we’re talking about whether some things are self-evident, we can also discuss whether this is “pretty obvious”. Discuss it here, if not at UD. Sewell is of course welcome to join in.

2LOT and ID entropy calculations (editorial corrections welcome)

Some may have wondered why me (a creationist) has taken the side of the ID-haters with regards to the 2nd law. It is because I am concerned for the ability of college science students in the disciplines of physics, chemistry and engineering understanding the 2nd law. The calculations I’ve provided are textbook calculations as would be expected of these students.

Entropy and Disorder from a creationist book endorsed by a Nobel Laureate

Here is an online creationist/ID book.
From http://www.ccel.us/gange.app.html#App

“I was particularly pleased with Dr. Gange’s refusal of the idea of materialism, and the convincing arguments supporting that refusal. In fact, the book will be a welcome response to materialism. Good luck, for a good book!”

Eugene Wigner, Nobel Laureate in Physics

The book had an appendix on thermodynamics.

“We noted earlier that entropy can be correlated-but not identified-with disorder. And we said, moreover, that this correlation is valid in only three cases-ideal gases, isotope mixtures, and crystals near zero degrees Kelvin. The truth of the matter is illustrated by considering the two chemically inert gases, helium, and argon.(7) In our mind’s eye we imagine two balloons, one filled with helium and the other with argon. First, we lower the temperature of both balloons to zero degrees Kelvin. This makes all the gas molecules stop moving in either balloon. Next, we get the molecules moving by heating both balloons to 300 degrees Kelvin (room temperature). Were we to mathematically calculate the increase in entropy, we would find that it was 20 percent higher in the argon balloon than in the helium balloon (154 v. 127 joules per mole per degree Kelvin). But since helium molecules are ten times lighter than argon molecules, they are moving three times faster and thus are more disordered. Here, then, is an example where higher entropy is accompanied by lower disorder, thereby demonstrating that we cannot identify one with the other. In the particular example cited, the greater argon entropy comes from the closer quantum translational energy levels identified with its greater molecular mass as described by the Sackŭr-Tetrode equation.

Configuration and Configurational Entropy

From Wiki:

http://en.wikipedia.org/wiki/Configuration_entropy

In statistical mechanics, configuration entropy is the portion of a system’s entropy that is related to the position of its constituent particles rather than to their velocity or momentum. It is physically related to the number of ways of arranging all the particles of the system while maintaining some overall set of specified system properties, such as energy. The configurational entropy is also known as microscopic entropy or conformational entropy in the study of macromolecules. In general, configurational entropy is the foundation of statistical thermodynamics.[1]

A Designed Object’s Entropy often Increases with Its Complexity

[This is an abridged version of a post at UD: A Designed Objects Entropy Must Increase for Its Design Complexity to Increase, Part 2. I post it under a different title at TSZ, because upon consideration, the new title should be above reproach. What I put forward should happily apply to man-made designs. A student recently wanted to challenge his professors regarding the 2nd law and evolution, and I pointed him to my essay. If that student is a creationist, at least I feel I did my job and made him understand science better than he would from most creationist literature. Hence, the rather torturous discussions at TSZ and UD had benefit in furthering this student’s understanding of science. If he is going to reject Darwinism, he should reject it for good reasons, not because of the 2nd law.]

In order for a biological system to have more biological complexity, it often requires a substantial increase in thermodynamic entropy, not a reduction of it, contrary to many intuitions among creationists and IDists. This essay is part II of a series that began with Part 1

Wolfram’s “A New Kind of Science”

I’ve just started reading it, and was going to post a thread, when I noticed that Phinehas also brought it up at UD, so as I kind of encouragement for him to stick around here for a bit, I thought I’d start one now:)

I’ve only read the first chapter so far (I bought the hardback, but you can read it online here), and I’m finding it fascinating.  I’m not sure how “new” it is, but it certainly extends what I thought I knew about fractals and non-linear systems and cellular automata to uncharted regions.  I was particularly interested to find that some aperiodic patterns are reversable, and some not – in other words, for some patterns, a unique generating rule can be inferred, but for others not.  At least I think that’s the implication.

Has anyone else read it?

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.”

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.

Granville Sewell vs Bob Lloyd

Bob Lloyd, professor emeritus of chemistry at Trinity College Dublin, wrote an opinion article in Mathematical Intelligencer (MI) commenting on Sewell’s not-quite-published AML article. This was mentioned in a previous thread, where Bob briefly commented. Granville was invited to participate but never showed up.

In response to Lloyd, Sewell submitted a letter to the editor. On advice of a referee, his letter was rejected. (Rightly so, in my view. More on that later.) Sewell has now written a post on Discovery Institute’s blog describing his latest misfortune. The post contains Sewell’s unpublished letter and some of the referee’s comments. I invite you to continue the technical discussion of Sewell’s points started earlier.

A Second Look at the Second Law…

…is the title of Granville Sewell’s manuscript that almost got published in Applied Mathematics Letters last year. It was withdrawn at the last minute by the editor, but you can still download the manuscript from Sewell’s web page. The purpose of this thread is to discuss the technical merits of Sewell’s arguments.
