Dr. Walter L. Bradley (C.V. here) is the Distinguished Professor of Engineering at Baylor.

Here’s a bio:

Walter Bradley (B.S., Ph.D. University of Texas at Austin) is Distinguished Professor of Engineering at Baylor. He comes to Baylor from Texas A&M University where he helped develop a nationally recognized program in polymeric composite materials. At Texas A&M, he served as director of the Polymer Technology Center for 10 years and as Department Head of Mechanical Engineering, a department of 67 professors that was ranked as high as 12th nationally during his tenure. Bradley has authored over 150 refereed research publications including book chapters, articles in archival journals such as the Journal of Material Science, Journal of Reinforced Plastics and Composites, Mechanics of Time-Dependent Materials, Journal of Composites Technology and Research, Composite Science and Technology, Journal of Metals, Polymer Engineering and Science, and Journal of Materials Science, and refereed conference proceedings.

Dr. Bradley has secured over $5.0 million in research funding from NSF grants (15 yrs.), AFOSR (10 years), NASA grants (10 years), and DOE (3 years). He has also received research grants or contracts from many Fortune 500 companies, including Alcoa, Dow Chemical, DuPont, 3M, Shell, Exxon, Boeing, and Phillips.

He co-authored The Mystery of Life Origin: Reassessing Current Theories and has written 10 book chapters dealing with various faith science issues, a topic on which he speaks widely.

He has received 5 research awards at Texas A&M University and 1 national research award. He has also received two teaching awards. He is an Elected Fellow of the American Society for Materials and the American Scientific Affiliation (ASA), the largest organization of Christians in Science and Technology in the world. He is President elect of the ASA and will serve his term in 2008.

You can read more about his recent research in this article from Science Daily.

Below, I analyze a lecture entitled “Is There Scientific Evidence for an Intelligent Designer?”. Dr. Bradley explains how the progress of science has made the idea of a Creator and Designer of the universe more acceptable than ever before.

The MP3 file is here.

Evidence #1: The design of the universe

1. The correspondence of natural phenomena to mathematical law

  • All observations of physical phenomena in the universe, such as throwing a ball up in the air, are described by a few simple, elegant mathematical equations.

2. The fine-tuning of physical constants and rations between constants in order to provide a life-permitting universe

  • Life has certain minimal requirements; long-term stable source of energy, a large number of different chemical elements, an element that can serve as a hub for joining together other elements into compounds, etc.
  • In order to meet these minimal requirements, the physical constants, (such as the gravitational constant), and the ratios between physical constants, need to be withing a narrow range of values in order to support the minimal requirements for life of any kind.
  • Slight changes to any of the physical constants, or to the rations between the constants, will result in a universe inhospitable to life.
  • The range of possible ranges over 70 orders of magnitude.
  • Although each individual selection of constants and ratios is as unlikely as any other selection, the vast majority of these possibilities do not support the minimal requirements of life of any kind. (In the same way as any hand of 5 cards that is dealt is as likely as any other, but you are overwhelmingly likely NOT to get a royal flush. In our case, a royal flush is a life-permitting universe).

Examples of finely-tuned constants and ratios: (there are more examples in the lecture)

a) The strong force: (the force that binds nucleons (= protons and neutrons) together in nucleus, by means of meson exchange)

  • if the strong force constant were 2% stronger, there would be no stable hydrogen, no long-lived stars, no hydrogen containing compounds. This is because the single proton in hydrogen would want to stick to something else so badly that there would be no hydrogen left!
  • if the strong force constant were 5% weaker, there would be no stable stars, few (if any) elements besides hydrogen. This is because you would NOT be able to build up the nuclei of the heavier elements, which contain more than 1 proton.
  • So, whether you adjust the strong force up or down, you lose stars than can serve as long-term sources of stable energy, or you lose chemical diversity, which is necessary to make beings that can perform the minimal requirements of living beings. (see below)

b) The conversion of beryllium to carbon, and carbon to oxygen

  • Life requires carbon in order to serve as the hub for complex molecules, but it also requires oxygen in order to create water.
  • Carbon is like the hub wheel in a tinker toy set: you can bind other elements together to more complicated molecules (e.g. – “carbon-based life), but the bonds are not so tight that they can’t be broken down again later to make something else.
  • The carbon resonance level is determined by two constants: the strong force and electromagnetic force.
  • If you mess with these forces even slightly, you either lose the carbon or the oxygen.

3. Fine-tuning to allow a habitable planet

  • A number of factors must be fine-tuned in order to have a planet that supports life
  • Initial estimates predicted abundant life in the universe, but revised estimates now predict that life is almost certainly unique in the galaxy, and probably unique in the universe.
  • Even though there are lots of stars in the universe, the odds are against any of them supporting complex life.
  • Here are just a few of the minimal requirements for habitability: must be a single star solar system, in order to support stable planetary orbits, the planet must be the right distance from the sun in order to have liquid water at the surface, the planet must sufficient mass in order to retain an atmosphere, etc.

The best non-theistic response to this argument is to postulate a multiverse, but that is very speculative and there is no experimental evidence that supports it.

Evidence #2: The origin of the universe

1. The progress of science has shown that the entire physical universe came into being out of nothing (= “the big bang”). It also shows that the cause of this creation event is non-physical and non-temporal. The cause is supernatural.

  • Atheism prefers an eternal universe, to get around the problem of a Creator having to create the universe.
  • Discovery #1: Observations of galaxies moving away from one another confirms that the universe expanded from a single point.
  • Discovery #2: Measurements of the cosmic background radiation confirms that the universe exploding into being.
  • Discovery #3: Predictions of elemental abundances prove that the universe is not eternal.
  • Discovery #4:The atheism-friendly steady-state model and oscillating model were both falsified by the evidence.
  • And there were other discoveries as well, mentioned in the lecture.

The best non-theistic response to this argument is to postulate a hyper-universe outside of ours, but that is very speculative and there is no experimental evidence that supports it.

Evidence #3: The origin of life

1. The progress of science has shown that the simplest living organism contains huge amounts of biological information, similar to the Java code I write all day at work. This is a problem for atheists, because the sequence of instructions in a living system has to come together all at once, it cannot have evolved by mutation and selection – because there was no replication in place prior to the formation of that first living system!

  • Living systems must support certain minimum life functions: processing energy, storing information, and replicating.
  • There needs to be a certain amount of complexity in the living system that can perform these minimum functions.
  • But on atheism, the living system needs to be simple enough to form by accident in a pre-biotic soup, and in a reasonable amount of time.
  • The minimal functionality in a living system is a achieved by DNA, RNA and enzymes. DNA and RNA are composed of sequences of proteins, which are in turn composed of sequences of amino acids.

Consider the problems of building a chain of 100 amino acids

  • The amino acids must be left-handed only, but left and right kinds are equally abundant in nature. How do you sort out the right-handed ones?
  • The amino acids must be bound together using peptide bonds. How do you prevent other types of bonds?
  • Each link of the amino acid chain needs to be carefully chosen such that the completed chain with fold up into a protein. How do you choose the correct amino acid for each link from the pool of 20 different kinds found in living systems?
  • In every case, a human or other intelligence could solve these problems by doing what intelligent agents do best: making choices.
  • But who is there to make the choices on atheism?

The best current non-theistic response to this is to speculate that aliens may have seeded the Earth with life at some point in the past.

The problem of the origin of life is not a problem of chemistry, it is a problem of engineering. Every part of car functionality can be understood and described using the laws of physics and chemistry. But an intelligence is still needed in order to assemble the components into a system that has the minimal requirements for a functioning vehicle.

Stephen C. Meyer and Peter Atkins debate intelligent design

This dialog occurred in 2010 on the Unbelievable radio show.

I made a rough transcript, so please see below for that.

The MP3 file is here. (60 minutes)

Details:

The documentary film “Expelled” is presented by US Actor Ben Stein and makes the case that scientists who question Darwinian orthodoxy and support Intelligent Design are being “expelled” from academia.

As the UK edition of the DVD is released we ask “Is freedom of thought at stake or is Intelligent Design out of bounds when it comes to biological science?”

Stephen C Meyer is co founder of the Discovery Institute in the USA and a major proponent of Intelligent Design.

Peter Atkins is Professor of Chemistry at Oxford University and an outspoken atheist.

They both feature in “Expelled” and join Justin to debate the pros and cons of Intelligent Design theory.

Mark Haville who is bringing the film to the UK also joins the discussion.

Note: The transcript below is quite snarky and may include paraphrases of Dr. Atkins for the sake of humor.

My rough transcript of the Meyer-Atkins debate

Stephen Meyer:
– started researching on ID while doing his PhD at Cambridge
– the question is whether the information-bearing properties in DNA require a designer
– what cause is adequate to explain the digital code that in the simplest living cell
– alternative explanations like self-organization and RNA-first have failed
– so the best explanation for functional sequences of parts is an intelligent designer
– Darwinists have responded to this argument with insults and suppression of dissent

Peter Atkins:
– intelligent design is creationism
– there is no science at all in it
– information can emerge without an intelligent designer
– structures emerge spontaneously, no agent is needed to generate the structure
– information in DNA is also a structure

Stephen Meyer:
– structure and information are two different things
– many structures emerge spontaneously
– structure may be like the vortex that occurs when water goes down a drain

Peter Atkins:
– the vortex is information

Stephen Meyer:
– structures are different from functionally-specified digital information
– in DNA, there is a 4-digit alphabet that is used to create code sequences
– the thing to be explained is where do the functional sequences come from

Peter Atkins:
– information can grow without an agent
– the second law of thermodynamics
– the universe is falling into disorder
– but there are local abatements of chaos that create information
– evolution can cause the amount of information to grow

Stephen Meyer:
– that’s just an assertion
– I agree that energy flow through a system can produce spontaneous order
– but spontaneous order is not the same thing as information

Peter Atkins:
– spontaneous order is the same as information

Stephen Meyer:
– it’s not order that needs to be explained it’s specified complexity

Peter Atkins:
– what do you mean by specified complexity?

Stephen Meyer:
– the chemical bonds that connect to each letter do not determine the letter
– the chemical bonding sites will accept any letter as easily as any other
– any one of the 4 bases (letters) can attach at any place along the backbone

Peter Atkins:
– the selection of which letter comes next is determined by evolution

Stephen Meyer:
– that is just an assertion
– there is no physical process that sequences the letters to have a function

Peter Atkins:
– do you believe in evolution? YES OR NO!

Mark Haville:
– for him to answer the question you have to define the word
– do you mean macro or micro? biological or stellar? directed or undirected?

Peter Atkins:
– undirected molecules to man evolution by natural processes

Stephen Meyer:
– but even Dawkins doesn’t believe in evolution then
– you’re including the origin of life from non-living matter in evolution
– Dawkins says that there is no known naturalistic explanation for that

Mark Haville:
– you need to define your terms

[They discuss of the movie Expelled and the case of Richard Sternberg]

Stephen Meyer:
– the problem is people don’t want to talk about the science
– they denounce dissent as unscientific
– they will not debate about whther natural causes can explain the information
– I want to talk about the science

Peter Atkins:
– ID people raise interesting questions for naturalists to work on
– but you want to tell us what the answer is (intelligence) before we begin
– you start from the idea that an intelligence was involved

Justin Brierley:
– but you start with the idea that natural mechanisms can explain everything!

Stephen Meyer:
– for Dr. Atkins, only explanations based on material processes are valid

Peter Atkins:
– that is correct

Stephen Meyer:
– but we think that the activities of mind can explain some effects
– e.g. – the best explanation of the Rosetta stone is a mind

Peter Atkins:
– but we naturalists think of minds as material as well

Stephen Meyer:
– that’s a materialist pre-supposition on your part
– we would have to have a debate about mind and body

Mark Haville:
– I think that the materialist position is socially dangerous
– the problem with naturalism is that it is an ideology
– the ideology pushes absurdities, e.g. – the universe came from nothing uncaused
– and naturalists exert power over others to force them to believe nonsense

Stephen Meyer:
– science progresses as the result of scientists disagreeing
– both sides agree to the facts
– the debate is about the interpretation of those facts
– and one side is being ruled out a priori based on the pre-supposition of materialism

Peter Atkins:
– why do you say that an intelligence is involved in DNA but not general relativity

Stephen Meyer:
– it is always logically possible that intelligence can be invlved in any effect
– the main thing is that explanations based on intelligence should not be ruled out

Peter Atkins:
= well you can’t appeal to any non-material process in expaining anything
– those are the rules

Moderator:
– what does intelligent design have to do with religion?

Stephen Meyer:
– creationism is about understanding the istory of life using the Bible
– intelligent design is about using the same method of inquiry as Darwin
– we know that information arises from intelligent causes
– humans create information all the time by using intelligence to sequence parts

Moderator:
– are intelligent design proponents disreputable?

Stephen Meyer:
– what’s disreputable is shutting down debate by setting arbitrary rules

Peter Atkins:
– we are both interested in the same questions

Moderator:
– why won’t you let Stephen publish his papers then?

Peter Atkins:
– because it breaks the pre-suppositions of naturalism and materialism

Stephen Meyer:
– you’re shutting down inquiry by using an arbitrary definition of science

Mark Haville:
– we need to define the word science
– science should be based on what we can observe empirically
– we can observe micro-evolution empirically
– but Darwinism goes beyond what is observable to postulate macro-evolution

Peter Atkins:
– but paleobiology is replete with evidence

Stephen Meyer:
– paleobiology uses a method of inference that I think is valid
– but intelligent design uses the same mode of reasoning which is also valid

Peter Atkins:
= you’re intellectually lazy
– we’re smart, we’re using our brains

Moderator:
– you’re saying that appeals to intelligent causes ends science?
– is ID the view that some things are too complex to be explained with naturalism?

Peter Atkins:
– yes, and to teach children that materialism is false is child abuse

Stephen Meyer:
– let’s drop the insults and the rhetoric and focus on the arguments
– the ID argument is not based on what we don’t know, it’s based on what we DO know
– first, we can ask what undirected natural processes can and cannot do
– second, we can ask what we know about intelligent causes from our own experience
– what we do know seems to me to require an intelligent agent as a cause

Peter Atkins:
– GOD! Do you mean God!? Do you mean God!?

Stephen Meyer:
– I personally mean God, but all that the arguments proves is a generic intelligent cause
– and I am using the same method of investigation that Darwin used to get there
– what we know from our experience is that a mind is needed to create information

Peter Atkins:
– NONSENSE! ABSOLUTE NONSENSE!

Stephen Meyer:
– in my book, I list 10 predictions made by ID, so it’s not a science-stopper
– furthermore, the enterprise of science began with th goal of understanding God
– consider the earliest scientists, people like James Boyler and Johannes Kepler

Peter Atkins:
– that was 300 years ago, we’ve moved on

Mark Haville:
– what about Max Planck then?

Stephen Meyer:
– how about James Clark Maxwell?

Mark Haville:
– we need to focus on the facts

Peter Atkins:
– what do you mean by the facts?

Mark Haville:
– well the fact is that Darwinism has no mechanism to produce new information

Peter Atkins:
– well copying errors introduces beneficial mutations

Stephen Meyer:
– let’s focus on where we get the first information from the simplest organism
– you can’t account for the first organism by appealing to copying errors
– to add functionality to a program, you need new lines codes from an intelligence
– once you have life, you can generate some new information
– but you can’t generate macro-evolution either

Peter Atkins:
– if we give you your explanation for teh origin of life, will you give this up

Stephen Meyer:
– of course! I’m a former theistic evolutionist
– but right now the evidence is not there for it
– we have to decide these questions based on what we see with our own eyes today

Peter Atkins:
– but I pre-suppose materialism as the starting point of all explanations
– you’re just intellectually lazy to abandon my pre-supposition

Stephen Meyer:
– why is it is less intellectually lazy to insist that materialism is true
– we are making plenty of predictions, and isn’t that what science is about?
– consider Junk DNA – you guys said it had no use
– now we know it has a use

Peter Atkins:
– naturalists were open to the idea that junk DNA might have a use before ID

Moderator:
– Dr. Meyer, what about the wall that locks out intelligence as an explanation?

Stephen Meyer:
– if these are interesting questions, then we should allow freedom of inquiry
– that’s how science advances

Peter Atkins:
– for all their science-talk really they are just saying God did it
– people who don’t agree with me are not using their brains, like I do
– to give up on my pre-supposition of materialism is a denial of humanity

Mark Haville:
– there are important issues that are affected by our view of origins
– everyone who hasn’t seen Expelled movie should definitely see it

Stephen C. Meyer and Marcus Ross lecture on the Cambrian explosion

Access Research Network is a group that produces recordings  of lectures and debates related to intelligent design. I noticed that on their Youtube channel they are releasing some of their older lectures and debates for FREE. So I decided to write a summary of one that I really like on the Cambrian explosion. This lecture features Dr. Stephen C. Meyer and Dr. Marcus Ross.

The lecture is about two hours. There are really nice slides with lots of illustrations to help you understand what the speakers are saying, even if you are not a scientist.

Here is a summary of the lecture from ARN:

The Cambrian explosion is a term often heard in origins debates, but seldom completely understood by the non-specialist. This lecture by Meyer and Ross is one of the best overviews available on the topic and clearly presents in verbal and pictorial summary the latest fossil data (including the recent finds from Chengjiang China). This lecture is based on a paper recently published by Meyer, Ross, Nelson and Chien “The Cambrian Explosion: Biology’s Big Bang” in Darwinism, Design and Public Education(2003, Michigan State University Press). This 80-page article includes 127 references and the book includes two additional appendices with 63 references documenting the current state of knowledge on the Cambrian explosion data. 

The term Cambrian explosion describes the geologically sudden appearance of animals in the fossil record during the Cambrian period of geologic time. During this event, at least nineteen, and perhaps as many as thirty-five (of forty total) phyla made their first appearance on earth. Phyla constitute the highest biological categories in the animal kingdom, with each phylum exhibiting a unique architecture, blueprint, or structural body plan. The word explosion is used to communicate that fact that these life forms appear in an exceedingly narrow window of geologic time (no more than 5 million years). If the standard earth’s history is represented as a 100 yard football field, the Cambrian explosion would represent a four inch section of that field.

For a majority of earth’s life forms to appear so abruptly is completely contrary to the predictions of Neo-Darwinian and Punctuated Equilibrium evolutionary theory, including:

  • the gradual emergence of biological complexity and the existence of numerous transitional forms leading to new phylum-level body plans;
  • small-scale morphological diversity preceding the emergence of large-scale morphological disparity; and
  • a steady increase in the morphological distance between organic forms over time and, consequently, an overall steady increase in the number of phyla over time (taking into account factors such as extinction).

After reviewing how the evidence is completely contrary to evolutionary predictions, Meyer and Ross address three common objections: 1) the artifact hypothesis: Is the Cambrian explosion real?; 2) The Vendian Radiation (a late pre-Cambrian multicellular organism); and 3) the deep divergence hypothesis.

Finally Meyer and Ross argue why design is a better scientific explanation for the Cambrian explosion. They argue that this is not an argument from ignorance, but rather the best explanation of the evidence from our knowledge base of the world. We find in the fossil record distinctive features or hallmarks of designed systems, including:

  • a quantum or discontinuous increase in specified complexity or information
  • a top-down pattern of scale diversity
  • the persistence of structural (or “morphological”) disparities between separate organizational systems; and
  • the discrete or novel organizational body plans

When we encounter objects that manifest any of these several features and we know how they arose, we invariably find that a purposeful agent or intelligent designer played a causal role in their origin.

Recorded April 24, 2004. Approximately 2 hours including audience Q&A.

You can get a DVD of the lecture and other great lectures from Access Research Network. I recommend their origin of life lectures – I have watched the ones with Dean Kenyon and Charles Thaxton probably a dozen times each. Speaking as an engineer, you never get tired of seeing engineering principles applied to questions like the origin of life.

The Cambrian explosion lecture above is a great intermediate-level lecture and will prepare you to be able to understand Dr. Meyer’s new book “Darwin’s Doubt: The Explosive Origin of Animal Life and the Case for Intelligent Design“. The Michigan State University book that Dr. Meyer mentions is called “Darwin, Design and Public Education“. That book is one of the two good collections on intelligent design published by academic university presses, the other one being from Cambridge University Press, and titled “Debating Design: From Darwin to DNA“. If you think this lecture is above your level of understanding, then be sure and check out the shorter and more up-to-date DVD “Darwin’s Dilemma“.

Mark D. Linville: does Darwinian evolution make morality rational?

Have you ever heard an atheist tell you that naturalistic evolution is an answer to the moral argument? I have. And I found a good reply to this challenge in the book “Contending With Christianity’s Critics“. The chapter that responds to the challenge is authored by Dr. Mark D. Linville. It is only 13 pages long. I have a link to the PDF at the bottom of this post.

First, a bit about the author:

Blog: The Tavern at the End of the World
Current positions:

  • PhD Research Fellow
  • Tutoring Fellow in Philosophy

Education:

  • PhD in Philosophy with a minor in South Asian Studies and a specialization in Philosophy of Religion, University of Wisconsin-Madison
  • MA in Philosophy, University of Wisconsin-Madison
  • MA in Philosophy of Religion, Trinity Evangelical Divinity School
  • MA in Theology, Cincinnati Christian Seminary
  • BA in Biblical Studies, Florida Christian College

Here is his thesis of the essay:

Darwin’s account of the origins of human morality is at once elegant, ingenious, and, I shall argue, woefully inadequate. In particular, that account, on its standard interpretation, does not explain morality, but, rather, explains it away . We learn from Darwin not how there could be objective moral facts, but how we could have come to believe—perhaps erroneously—that there are.

Further, the naturalist, who does not believe that there is such a personal being as God, is in principle committed to Darwinism, including a Darwinian account of the basic contours of human moral psychology. I’ll use the term evolutionary naturalism to refer to this combination of naturalism and Darwinism. And so the naturalist is saddled with a view that explains morality away. Whatever reason we have for believing in moral facts is also a reason for thinking naturalism is false. I conclude the essay with a brief account of a theistic conception of morality, and argue that the theist is in a better position to affirm the objectivity of morality.

And here’s a sample to get your attention:

But even if we are assured that a “normal” person will be prompted by the social instincts and that those instincts are typically flanked and reinforced by a set of moral emotions, we still do not have a truly normative account of moral obligation. There is nothing in Darwin’s own account to indicate that the ensuing sense of guilt—a guilty feeling—is indicative of actual moral guilt resulting from the violation of an objective moral law. The revenge taken by one’s own conscience amounts to a sort of second-order propensity to feel a certain way given one’s past relation to conflicting first-order propensities (e.g., the father’s impulse to save his child versus his impulse to save himself). Unless we import normative considerations from some other source, it seems that, whether it is a first or second-order inclination,one’s being prompted by it is more readily understood as a descriptive feature of one’s own psychology than material for a normative assessment of one’s behavior or character. And, assuming that there is anything to this observation, an ascent into even higher levels of propensities (“I feel guilty for not having felt guilty for not being remorseful over not obeying my social instincts…”) introduces nothing of normative import. Suppose you encounter a man who neither feels the pull of social, paternal or familial instincts nor is in the least bit concerned over his apparent lack of conscience. What, from a strictly Darwinian perspective, can one say to him that is of any serious moral import? “You are not moved to action by the impulses that move most of us.” Right. So?

The problem afflicts contemporary construals of an evolutionary account of human morality. Consider Michael Shermer’s explanation for the evolution of a moral sense—the “science of good and evil.” He explains,

By a moral sense, I mean a moral feeling or emotion generated by actions. For example, positive emotions such as righteousness and pride are experienced as the psychological feeling of doing “good.” These moral emotions likely evolved out of behaviors that were reinforced as being good either for the individual or for the group.2

Shermer goes on to compare such moral emotions to other emotions and sensations that are universally experienced, such as hunger and the sexual urge. He then addresses the question of moral motivation.

In this evolutionary theory of morality, asking “Why should we be moral?” is like asking “Why should we be hungry?” or “Why should we be horny?” For that matter, we could ask, “Why should we be jealous?” or “Why should we fall in love?” The answer is that it is as much a part of human nature to be moral as it is to be hungry, horny, jealous, and in love.3

Thus, according to Shermer, given an evolutionary account, such a question is simply a non-starter. Moral motivation is a given as it is wired in as one of our basic drives. Of course, one might point out that Shermer’s “moral emotions” often do need encouragement in a way that, say, “horniness,” does not. More importantly, Shermer apparently fails to notice that if asking “Why should I be moral?” is like asking, “Why should I be horny?” then asserting, “You ought to be moral” is like asserting, “You ought to be horny.” As goes the interrogative, so goes the imperative. But if the latter seems out of place, then, on Shermer’s view, so is the former.

One might thus observe that if morality is anything at all, it is irreducibly normative in nature. But the Darwinian account winds up reducing morality to descriptive features of human psychology. Like the libido, either the moral sense is present and active or it is not. If it is, then we might expect one to behave accordingly. If not, why, then, as a famous blues man once put it, “the boogie woogie just ain’t in me.” And so the resulting “morality” is that in name only.

In light of such considerations, it is tempting to conclude with C. S. Lewis that, if the naturalist remembered his philosophy out of school, he would recognize that any claim to the effect that “I ought” is on a par with “I itch,” in that it is nothing more than a descriptive piece of autobiography with no essential reference to any actual obligations.

When it comes to morality, we are not interested in mere descriptions of behavior. We want to know about prescriptions of behavior, and whether why we should care about following those prescriptions. We are interested in what grounds our sense of moral obligation in reality. What underwrites our sense of moral obligation? If it is just rooted in feelings, then why should we obey our moral sense when obeying it goes against out self-interest? Feelings are subjective things, and doing the right thing in a real objective state of affairs requires more than just feelings. There has to be a real objective state of affairs that makes it rational for us to do the right thing, even when the right thing is against our own self-interest. That’s what morality is – objective moral obligations overriding subjective feelings. I wouldn’t trust someone to be moral if it were just based on their feelings.

Philip E. Johnson lectures on science, evolution and religion

I found this fun lecture by the grandfather of the big-tent intelligent design movement, Berkeley law professor Philip E. Johnson.

I’ll bet you guys have all heard of him, but you’ve never heard him speak, right? Well, I was a young man, I used to listen to Phil’s lectures and his debates with Eugenie Scott quite a bit. This is one of my favorite lectures. Very easy to understand, and boilerplate for anything else in the origins debate. This is a great lecture – funny, engaging and useful. You will definitely listen to this lecture several times if you listen to it once.

The MP3 is here. (91 minutes, 62 megabytes)

The Inherit the Wind stereotype

  • Many people get their understanding of origins by watching movies like “Inherit the Wind” (or reading science fiction)
  • The actual events of the Scopes trial are nothing like what the movie portrays
  • The law forbidding the teaching of evolution was symbolic, not meant to be enforced
  • The actual Scopes trial was a publicity stunt to attract attention to Dayton, TN to bring business to the town
  • The ACLU advertised for a teacher who would be willing to be sued
  • They found a substitute physical education teacher who would be willing to “break” the law
  • The movie is nothing like the actual events the movie is a morality play
  • The religious people are evil and stupid and ignorant and bigoted
  • The scientists and lawyers are all intelligent, romantic, and honest seekers of the truth
  • The religious people think that the Bible trumps science and science is not as reliable as the Bible
  • The movie argues that the reason why there is ANY dissent to evolution is because of Biblical fundamentalism
  • The movie presents the idea that there are no scientific problems with evolution
  • The movie says that ONLY Biblical fundamentalists who believe in 6 day, 24-hour creation doubt evolution
  • The movie says that Biblical fundamentalism are close-minded, and not open to scientific truth
  • The movie says that people who read the Bible as making factual claims are misinterpreting the Bible
  • The movie says that smart people read the Bible for comfort and feelings and arbitrary values, not for truth

Guided evolution and methodological naturalism

  • What scientists mean by evolution is that fully naturalistic, unguided, materialistic mechanisms caused the diversity of life
  • Scientists do not allow that God had any real objective effect on how life was created
  • Scientists think that nature did all the creating, and any mention of God is unnecessary opinion – God didn’t DO ANYTHING
  • Scientists operate with one overriding rule – you can only explain the physical world with physical and material causes
  • Scientists DO NOT allow that God could have done anything detectable by the sciences
  • Scientists WILL NOT consider the idea that natural, material processes might be INSUFFICIENT for explaining everything in nature
  • You cannot even ask the question about whether natural laws, matter and chance can explain something in nature
  • Intelligent causes can NEVER be the explanation for anything in nature, and you can’t even test experimentally to check that
  • Scientists ASSUME that everything can be explained with natural laws, matter and chance – no questioning of natural causes is allowed
  • Where no natural explanation of a natural phenomenon is available, scientists SPECULATE about undiscovered natural explanations
  • The assumption of naturalistic sufficiency is called “methodological naturalism”
  • To question the assumptions that natural is all there is, and that nature has to do its own creating, makes you an “enemy of science”
  • But Johnson says that naturalists are the enemies of science, because they are like the Biblical fundamentalists
  • Naturalists have a presumption that prevents them from being willing to follow the evidence where it is leading
  • Experiments are not even needed, because the presumption of naturalism overrides any experimental finding that falsifies the sufficiency of natural causes to explain some natural phenomenon

What can natural selection and mutation actually do?

  • what evolution has actually been observed to do is explain changing populations of moths and finches
  • finches with smaller or larger beaks are observed to have differential survival rates when there are droughts or floods
  • no new body plan or new organ type has been observed to emerge from these environmental pressures
  • the only kind of evolution that has been observed is evolution within types – no new genetic instructions are created
  • in textbooks, only confirming examples are presented – but what is required is a broad pattern of gradual development of species
  • if you look at the fossil record, what you see in most cases is variation within types based on changing environments
  • the real question is: can natural law and chance be observed to be doing any creating of body plans and organ types?

What kind of effect requires an intelligent cause?

  • the thing to be explained in the history of life is the functional information sequences
  • you need to have a sequence of symbols or characters that is sufficiently long
  • your long sequence of characters has to be sequenced in the right order to have biological function
  • the only thing that can create long sequences of functional information is an intelligent cause
  • intelligent design people accept micro-evolution – changes within types – because that’s been observed
  • the real thing to be explained is the first living cell’s functional information, and the creation of new functional information

Critical response

The next 15 minutes of the lecture contain a critical response from a philosophy professor who thinks that there have been no developments in design arguments since Aquinas and Paley. He basically confirms the stereotypes that Johnson outlined in the first part of the lecture. I recommend listening to this to see what opposition to intelligent design really looks like. It’s not concerned with answering scientific questions – they want to talk about God, the Bible and Noah’s ark. It’s our job to get people like this critic to focus on the science.

Here’s my snarky rendition of what he said:

1) Don’t take the Bible literally, even if the genre is literal.

  • all opposition to evolution is based on an ignorant, fundamentalist, literal reading of the Bible
  • the Bible really doesn’t communicate anything about the way the world really is
  • the Bible is just meant to suggest certain opinions and experiences which you may find fetching, or not, depending on your feelings and community
  • if Christians would just interpret the Bible as myths and opinions on par with other personal preferences, then evolution is no threat to religious belief

2) As long as you treat the design argument as divorced from evidence, it’s not very effective

  • the latest and best version of the design argument is the old Paley argument which involves no experimental data, so I’ll critique that
  • this 200-year old argument which doesn’t rely on science has serious problems, and unnamed Christians agree with me!
  • Christians should NOT try to prove God’s existence using evidence from the natural world (as Romans 1 says), and in fact it’s “Pelagianism” to even try
  • Christians should divorce their faith from logic and evidence even though the Bible presents faith as being rooted in reason and evidence
  • Christians should not tie their faith to the science of today, because science is always changing and the theism-friendly evidence of today might be overturned tomorrow
  • It’s a good idea for me to critique the arguments of 1000-year old people who did not know anything about the cosmic fine-tuning argument – that’s fair!
  • I find it very useful to tell people that the argument from design is false without mentioning any design arguments from DNA or cosmic fine-tuning
  • We need to assume that the natural world is explainable using only natural causes before we look at any evidence
  • We should assume that natural causes create all life, and then rule out all experimental evidence for intelligent causes that we have today
  • As long as you accept that God is a personal opinion that has nothing to do with reality, then you can do science
  • The non-Christian process theologian Teilhard de Chardin accepts evolution, and therefore so should you
  • Remember when theists said God caused thunder because he was bowling in the clouds and then we found out he didn’t? Yeah well – maybe tomorrow we’ll find out that functional sequences of amino acids and proteins have natural causes! What would you do then?

3) What the Bible really says is that you should be a political liberal
