Is intelligent design creationism? Dr. Stephen C. Meyer explains

Dr. Meyer explains the truth in the UK Telegraph.

Excerpt:

In 2004, the distinguished philosopher Antony Flew of the University of Reading made worldwide news when he repudiated a lifelong commitment to atheism and affirmed the reality of some kind of a creator. Flew cited evidence of intelligent design in DNA and the arguments of “American [intelligent] design theorists” as important reasons for this shift.

[…]Contrary to media reports, ID is not a religious-based idea, but an evidence-based scientific theory about life’s origins. According to Darwinian biologists such as Oxford University’s Richard Dawkins, living systems “give the appearance of having been designed for a purpose”.

But, for modern Darwinists, that appearance of design is illusory, because the purely undirected process of natural selection acting on random mutations is entirely sufficient to produce the intricate designed-like structures found in living organisms.

By contrast, ID holds that there are tell-tale features of living systems and the universe that are best explained by a designing intelligence. The theory does not challenge the idea of evolution defined as change over time, or even common ancestry, but it disputes Darwin’s idea that the cause of biological change is wholly blind and undirected.

[…]Consider an even more fundamental argument for design. In 1953, when Watson and Crick elucidated the structure of the DNA molecule, they made a startling discovery. Strings of precisely sequenced chemicals called nucleotides in DNA store and transmit the assembly instructions – the information – in a four-character digital code for building the protein molecules the cell needs to survive. Crick then developed his “sequence hypothesis”, in which the chemical bases in DNA function like letters in a written language or symbols in a computer code. As Dawkins has noted, “the machine code of the genes is uncannily computer-like”.

The informational features of the cell at least appear designed. Yet, to date, no theory of undirected chemical evolution has explained the origin of the digital information needed to build the first living cell. Why? There is simply too much information in the cell to be explained by chance alone.

The information in DNA (and RNA) has also been shown to defy explanation by forces of chemical necessity. Saying otherwise would be like saying a headline arose as the result of chemical attraction between ink and paper. Clearly, something else is at work.

DNA functions like a software program. We know from experience that software comes from programmers. We know that information – whether, say, in hieroglyphics or radio signals – always arises from an intelligent source. As the pioneering information theorist Henry Quastler observed: “Information habitually arises from conscious activity.” So the discovery of digital information in DNA provides strong grounds for inferring that intelligence played a causal role in its origin.

Thus, ID is not based on religion, but on scientific discoveries and our experience of cause and effect, the basis of all scientific reasoning about the past. Unlike creationism, ID is an inference from biological data.

It might be a good idea now to echo Meyer’s claim with something from the secular magazine Scientific American.

Excerpt:

As recently as the middle of the 20th century, many scientists thought that the first organisms were made of self-replicating proteins. After Francis Crick and James Watson showed that DNA is the basis for genetic transmission in the 1950s, many researchers began to favor nucleic acids over proteins as the ur-molecules. But there was a major hitch in this scenario. DNA can make neither proteins nor copies of itself without the help of catalytic proteins called enzymes. This fact turned the origin of life into a classic chicken-or-egg puzzle: Which came first, proteins or DNA?

RNA, DNA’s helpmate, remains the most popular answer to this conundrum, just as it was when I wrote “In the Beginning…” Certain forms of RNA can act as their own enzymes, snipping themselves in two and splicing themselves back together again. If RNA could act as an enzyme, then it might be able to replicate itself without help from proteins. RNA could serve as gene and catalyst, egg and chicken.

But the “RNA-world” hypothesis remains problematic. RNA and its components are difficult to synthesize under the best of circumstances, in a laboratory, let alone under plausible prebiotic conditions. Once RNA is synthesized, it can make new copies of itself only with a great deal of chemical coaxing from the scientist. Overbye notes that “even if RNA did appear naturally, the odds that it would happen in the right sequence to drive Darwinian evolution seem small.”

The RNA world is so dissatisfying that some frustrated scientists are resorting to much more far out—literally—speculation. The most startling revelation in Overbye’s article is that scientists have resuscitated a proposal once floated by Crick. Dissatisfied with conventional theories of life’s beginning, Crick conjectured that aliens came to Earth in a spaceship and planted the seeds of life here billions of years ago. This notion is called directed panspermia. In less dramatic versions of panspermia, microbes arrived on our planet via asteroids, comets or meteorites, or drifted down like confetti.

Naturalists who resort to aliens are still implicating intelligent causes to explain life, ironically enough.

Please share and re-tweet this post, because not understanding intelligent design is a mistake that virtually everyone in the mainstream media makes when discussing this topic. I would bet $100 that there is not a single journalist in the mainstream media who can define intelligent design by citing a peer-reviewed article or academic textbook, and then give an example of where proponents of ID think that intelligent design is evident in nature.

Here are the 2 playlists:

Stephen C. Meyer and Keith Fox debate intelligent design and evolution

From Justin Brierley’s “Unbelievable” podcast.

Details:

Stephen Meyer is a leading proponent of Intelligent Design who directs the Centre for Science and Culture at the Discovery Institute in Seattle. His most recent book “Signature in the Cell” claims to show that the DNA code is the product of intelligent mind, not naturalistic processes. Keith Fox is Professor of Biochemistry at Southampton University. He chairs the UK Christians in Science network but disagrees strongly with ID. They debate how life could have originated and whether design is allowed as an explanation in science.

The MP3 file is here.

Summary: (stuff in italics is my snarky paraphrase)

Meyer:

  • background and how he got interested in intelligent design
  • his research focus is on the origin of life – the first replicator
  • summarizes the history of origin of life studies
  • authored the book “Signature in the Cell”
  • the DNA enigma: where did the information in DNA come from?
  • naturalistic explanations of the DNA information have failed
  • but intelligent agents are known to be able to produce information
  • the best explanation of the information in DNA is that an intelligent agent authored it
  • Meyer’s book was named by atheist philosopher of science Thomas Nagel as a Times Literary Supplement Book of the Year in 2010
  • why is design so controversial? Many people think that Darwin explained why nature appears design
  • the Darwinian view is that nature can create the appearance of design using mutation and selection
  • however, Darwinian mechanisms cannot explain the origin of the first living cell, it assumes replication, and the origin of life is about where the first replicator comes from

Fox:

  • Meyer’s argument is not about the evolution of life after the first cell
  • Meyer’s case for design is about the origin of life
  • naturalists do not know a naturalistic explanation for the origin of life
  • there are a number of naturalistic hypotheses for the origin of life, like the RNA-first hypothesis
  • maybe in a few years one of them will turn out to be correct
  • what intelligent design is arguing from a gap in our current naturalistic knowledge to infer that God intervened in nature

Meyer:

  • that’s not what intelligent design is at all
  • the approach ID theorists use is the inference to best explanation
  • you evaluate all explanations, non-intelligent causes and intelligent causes
  • you prefer the best possible explanation
  • we know that minds are capable of producing information just like the information we find in DNA

Fox:

  • living cells replicate, so they have the ability to introduce mutations as they replicate and then some of those mutations can be selected
  • so maybe the process of replicating that living cells do created the first living cell
  • maybe the first living cell created itself, X brought X into being, self-creation, what’s irrational about that?

Meyer:

  • the issue is the origin of life – where did the first living cell come from?
  • you cannot appeal to the operations that a living cell can perform to explain the origin of the first living cell
  • there was no first living cell operating before the first living cell
  • there was no replication, mutation or selection before the first living cell
  • in fact, in my book I show that there is no known naturalistic mechanism that is able to produce the information needed for the first living cell
  • nothing can create itself, that is self-contradictory
Fox:
  • Well, you are just saying that because something is complex that God did it
Meyer:
  • Sadly, no. What I actually said needed to be explained was the information, not complexity
  • And we know from software engineering that the process of adding information to code is performed by programmers
  • in the absence of any adequate naturalistic explanation for information, we are justified in taking the explanation that we are familiar with – namely, intelligent agency – based on our uniform, universal experience of what causes information
Fox:
  • well, maybe we can appeal to the mutation and selection in existing living cells to explain the origin of the first living cell
  • maybe there were living cells before the first living cell, and then these other living cells created the first living cell
Meyer:
  • we can’t keep invoking mutation and selection when those processes are not operating prior to the origin of the first living cell
Fox:
  • well maybe some bare-bones self-replication molecule was a precursor to the first living cell
Meyer:
  • even to generate very limited replicator would require a large amount of information
  • the argument I am making is – where does the evolution come from?
Fox:
  • well, maybe we will think of an explanation for information that is naturalistic in 20 years
  • we’ve thought of explanations to things that were NOT information before
  • so maybe we will be able to think of something to explain information based on our ability to explain NOT information before

Moderator: Change topics: the Dover decision

Meyer:

  • the Discovery Institute opposed the policy that causes the trial
  • the wording of the statute was poor
  • the judge was completely wrong in his decision
  • young earth creationists used the phrase “intelligent design” to cover their agenda
  • intelligent design is an inference using the normal methods of science
Fox:
  • intelligent design is a science stopper because it stops looking for a naturalistic explanation
  • everything in nature must have a naturalistic explanation
  • everything has to be explained using matter and time and chance
  • it just has to be that way!!!!
Meyer:
  • well, what luck would you have explaining an effect like Mt. Rushmore?
  • can you explain that using matter,time and chance?
  • Mt. Rushmore was the product of intelligence, not wind and erosion
  • similarly, there is information in the cell, and we know that intelligence causes information
Fox:
  • So you are saying that we don’t understand and therefore an intelligence is necessary?

Meyer:

  • no I am saying we DO understand and we are making an inference based on that understanding
  • you are the one who is insisting on a material explanation because you pre-suppose materialism
  • we know that minds have causal powers, and we can infer mind as an explanation from information
Fox:
  • well nature is a seamless chain of material causes and effects
Meyer:
  • agents can act without violating the laws of nature
  • even humans can act as intelligent agents to create information in books, and they don’t violate the laws of nature
  • intelligent causes are real, and they explain effects in nature
Fox:
  • you’re trying to impose on science something to do with meaning and purpose
Meyer:
  • no that’s not what we’re doing, we’re inferring from from the fact that we ourselves are known causes of information to the fact that an intelligence cause is the best explanation for information in the cell
Fox:
  • but I am a materialist, I need a materialist explanation
Meyer:
  • mind IS an answer to the how question
  • we infer to mind in many other scientific disciplines, like cryptography, archaeology, etc.
  • a materialist might accuse an archaeologist of engaging in a “scribe-of-the-gaps” argument, but the best explanation of an artifact with information is a scribe
  • we are inferring that mind is the cause from the nature of the effect: information
Moderator: is it appropriate to call DNA “information”

Fox:

  • well DNA is just a molecular polymer, any reference to information is just by analogy
Meyer:
  • DNA is a molecular polymer, but it also exhibits the property of specified complexity
  • the arrangement of bases, which function as machine instructions in a software program, for performings task in the cell
  • we have observed that the property of specified complexity always comes from an intelligence
Fox:
  • well, maybe there are other sequences that would work, so maybe it’s really not uncommon to develop functioning sequences by chance alone, without an intelligence
Meyer:
  • you can measure how precise the functional specificity is in DNA and proteins

Moderator: is Shannon information the same as functional information

Meyer:

  • Shannon information refers to the sequences of digits or symbols that do not necessarily have any function, i.e. – a four character string QSZX has as much Shannon information as WORD. However, only the latter is functional against the pattern of the English language. There are arrangements of DNA bases and amino acids that have the same number of symbols/characters as a functional sequence would have, but they have no biological function – they do not exhibit specified complexity
Fox:
  • Well, maybe there are lots and lots of sequences of DNA and proteins so that it is fairly easy to get a functional one by chance

Meyer:

  • DNA sequences that are functional are extremely rare, protein sequences are even more rare
  • this is not my opinion, this is what the research shows – functional protein sequences are rare
Fox:
  • well maybe there are other functional sequences that are occur before the first functional sequence that are precursors to the first functional sequence
  • maybe there are billions of years of replication, mutation and selection before the first replication, mutation and selection

Meyer:

  • you can’t get to the first selectable functional sequence by appealing to precursor selectable functional sequences – there are no selectable functional sequences before the FIRST one
  • you have to get the first selectable functional sequence by chance alone, because there is nothing to mutate or select before the first replicator
  • the chance hypothesis has been rejected because the minimal amount of information for the simplest replicator is too high to get by chance alone, given the resources, including time, that are available

Moderator: Keith are you confident that naturalism will be able to substantiate these naturalism-of-the-gap speculations that you offer in response to Meyer’s actual science that we have today? 

Fox:

  • well, it is hard to know for sure because it was just a fluke event
  • but there’s nothing irrational or unscientific or miraculous about it – the fluke would have a material explanation
  • there is nothing that we can detect that would implicate God, my speculations about a fluke which I cannot observe or measure or test would all be compatible with an atheistic worldview that omits God as a causal entity

Meyer:

  • where are those material processes that could account for this fluke then?
  • the whole point of this argument is that the information in DNA transcends the material components in the sequence
  • it’s the arrangement of the material parts/letters/characters/symbols/instructions that needs to be explained
Fox:
  • Well, I just have a different philosophy of science that rules out intelligent causation a priori

Meyer:

  • Yes, that’s the difference between us – you pre-suppose that all explanations of natural phenomena must exclude intelligent causes

There is a bit more where Meyer talks about how parts of the cell are implementations of various design patterns (Gang of Four design patterns) that are used by software architects who design software.

What is the case for intelligent design?

Everyone knows that blog posts and Java programs are the result of an intelligent agent, who arranges symbols into long, improbable sequences that have function. I write blog posts and I write Java programs, and both are the result of my intelligence sequencing letters by typing into my keyboard. Now what should we infer if we look at the universe and we see similar sequences that have functions?

This article from Evolution News explains how a person can look at the universe, find functional sequences of symbols, and infer a designer. (H/T J Warner Wallace of Please Convince Me)

Excerpt:

Intelligent design is a scientific theory that holds some aspects of life and the universe are best explained by reference to an intelligent cause. Why? Because they contain the type of complexity and information that in our experience comes only from intelligence.

As a result, intelligent-design theorists begin by studying how intelligent agents act when they design things. Intelligence is a process, or a mechanism, which we can observe at work in the world around us. Human designers make a great dataset for studying how intelligent agency works.

When we study the actions of humans, we learn that intelligent agents produce high levels of complex and specified information (CSI). Something is complex if it’s unlikely, and specified if it matches some independent pattern. William Dembski and Stephen Meyer explain that in our experience, only intelligent agents produce this type of information:

  • “[T]he defining feature of intelligent causes is their ability to create novel information and, in particular, specified complexity.” (William A. Dembski, No Free Lunch: Why Specified Complexity Cannot Be Purchased without Intelligence, p. xiv (Rowman & Littlefield Publishers 2002).)
  • “Agents can arrange matter with distant goals in mind. In their use of language, they routinely ‘find’ highly isolated and improbable functional sequences amid vast spaces of combinatorial possibilities.” (Stephen C. Meyer, “The Cambrian Information Explosion,” inDebating Design (edited by Michael Ruse and William Dembski; Cambridge University Press 2004).)

Meyer further explains that in our experience, only intelligence produces high levels of CSI:

[W]e have repeated experience of rational and conscious agents — in particular ourselves — generating or causing increases in complex specified information, both in the form of sequence-specific lines of code and in the form of hierarchically arranged systems of parts. … Our experience-based knowledge of information-flow confirms that systems with large amounts of specified complexity (especially codes and languages) invariably originate from an intelligent source, from a mind or personal agent.” (Stephen C. Meyer, “The origin of biological information and the higher taxonomic categories,” Proceedings of the Biological Society of Washington, Vol. 117(2):213-239 (2004).)Thus, in our experience, high levels of complex and specified information — such as in codes and languages — arise only from intelligence. By assessing whether natural structures contain the type of complexity — high CSI — that in our experience comes only from intelligence, we can construct a positive, testable case for design.

And what happens when we study nature? Well, the past 60 years of biology research have uncovered that life is fundamentally based upon:

  • A vast amount of complex and specified information encoded in a biochemical language;
  • A computer-like system of commands and codes that processes the information.
  • Molecular machines and multi-machine systems.

But where in our experience do things like language, complex and specified information, programming code, or machines come from? They have one and only one known source: intelligence.

One of the strangest things about intelligent design is how many people use the phrase without even being able to define it or point to an academic book or paper where the concept is defined.  There are several places where information is found in nature: the origin of life (“biological information”) and Cambrian explosion (“higher taxonomic categories”) are two of them. There is no known naturalistic method of producing large amounts of functional information in these two areas. But we know that human intelligence are capable of creating the sequences – we’ve seen it done. Intelligent design is the view that functional information sequences in nature are the result of intelligence. That’s all we know that can produce it.
