He even found a seat in the overcrowded flight lounge.

In “Confessions of an Atheist Darwin-Doubter”( Evolution News & Views, May 21, 2012), James Barham explains why a reasonable atheist can easily doubt Darwin:

By the 1980s, I had become conversant with the standard critiques of neo-Darwinism, such as Karl Popper’s. Also, from my classical studies, I was familiar with Aristotle. So, I knew there were problems with Darwinism as a metaphysical system, and that alternatives existed. Gradually, too, I became conscious of a growing cognitive dissonance between my Darwin-inspired philosophical materialism and reductionism, and my first-person experience of the fundamental importance of purpose, value, and meaning for human existence. I was familiar with various schemes that had been proposed for explaining away the latter, such as Daniel Dennett’s “intentional stance,” but I could see they were just evading the issue. So, I was left with a contradiction between two aspects of my mental life that I had no idea how to resolve.

Then, one day while browsing in the stacks — this was around 1988 — I stumbled across an essay collection entitled Self-Organizing Systems: The Emergence of Order (ed. F. Eugene Yates; Plenum Press, 1987). This volume was devoted to efforts that were then underway to use dynamical systems theory as a means of modeling the operation of various physiological systems. I immediately had the experience of the scales falling from my eyes. I saw in a flash that the concept of a nonlinear oscillator — and its associated “basin of attraction” — might be a way to model the end-directed, or teleological, feature of biological functions. (A basin of attraction — or “attractor,” for short — is a mathematical representation of dynamical behavior as a “trajectory” through an abstract multidimensional space.) And upon this foundation, I could already vaguely see that an emergentist metaphysics might be erected which might provide a robustly realist, yet rigorously scientific, account of the phenomena of purpose, value, and meaning.

I was aware of well-known criticisms of both of the then-current reductionist accounts of function: the “causal-role” theory and the Darwin-inspired “selected-effects” theory. In a nutshell, the problem is that neither theory can explain the normative character of biological processes in a coherent manner. (Biological processes are “normative” in the sense that they may either succeed or fail in fulfilling their functions.) With respect to the “causal-role” theory, there is no way to distinguish between functional and non-functional parts of a biological system without presupposing the normative character of the overall system as a whole — which begs the question at issue. … More.

Actually, it seems to be a trend. One thing the New Atheists have done, for which the public is surely in their debt, is to render atheism and Darwinism so odious that people who would not have questioned the Darwinists’ circled wagons and circular reasoning before now find that they must.

Eugene S @6: "Could you expound on this please. Thanks." Sure. This is a basic principle of information theory. The ability to carry any meaningful information depends on the ability of the medium to carry different digits (symbols, characters, molecules, whatever is being used) in aperiodic sequence. In contrast, self-organization posits that there is some kind of law-like process that causes certain elements to come together. This produces a repetitive sequence (like crystals), rather than an aperiodic sequence. Think of the simplest example: a two-bit digital code of ones and zeroes. With that code I can convey anything. However, now imagine that there is some kind of natural affinity between ones and zeroes that causes them to react with each other and self-organize in a particular way. Let's say, for example, that every time I have a zero it is always followed by a one. Now imagine trying to create a message or convey information with this two-bit system. I start writing my DVD, but every time I write a zero, it automatically places a one after it. I have now lost the ability to ever write zero-zero, or any string of zeroes. The information carrying capacity of the medium has been reduced. Further, if we have an additional self-organizational tendency, say every time we write a one it is followed by a zero, then I have now lost all ability to ever convey any information with this code. Every time I write a zero it is followed by a one; every time I write a one it is followed by a zero. I end up with '0101' over and over again in a repetitive pattern. This kind of repeating pattern is what we have with crystals (a law-like, self-organizing structure), but it is useless for conveying information. Similarly, if DNA nucleotides had a self-organizing tendency, say A and T interacted such that T always followed A, we would have a similar reduction in information-bearing capacity. Now every time we see an A it will automatically be followed by T. What that means in practice is that instead of 4 digits (A, T, C, G) we now have only a 3-digit code (AT, C, G). This significantly reduces our information-bearing capacity (in just 3 digits it drops from 64 to 27, and as we add digits the discrepancy is exponential). A lot of chemical analysis has been done with nucleotides to see if there is any affinity between the nucleotides and not much of consequence has been found. More importantly, in our DNA the nucleotides don't even interact in a meaningful way. They are suspended in the backbone, thereby ensuring that no self-organizing tendency exists between the nucleotides and that every possible combination is equally likely. Those who study DNA and information have recognized that it is precisely this ability for complete freedom in ordering the nuclotides that gives DNA its information-bearing capacity. Just to anticipate a potential question I should also briefly mention the following. The information-reducing problem still exists if, instead of an absolute tendency for T to follow A, there is a likelihood of T following A. In that case rather than having an absolute self-order, we simply have a statistical likelihood of the self-order. In either case, the ability to have an aperiodic information-rich sequence is reduced. ----- Thus, to the extent that two molecules tend to interact with each other (self-organize in some way), to that extent their information carrying capacity will be reduced. A lot of self-organizationalists tend to forget about this in their excitement to explain life as arising as some kind self-organizing manifestation of matter (typically because they have given up on 'chance' as a viable explanation and are turning to 'necessity' as the alternative). Incidentally, it was, in part, Dean Kenyon's recognition of this inverse proportionality between self-organization and information-bearing-capability that led him to ultimately repudiate his own self-organizational theory and consider design as an alternative. (He had already rejected chance as a realistic option.)Eric Anderson

Eric, Indeed, the ability of a medium to carry information is inversely proportional to the likelihood of it self-organizing. Could you expound on this please. Thanks.Eugene S

Self-organization is anathema to information-rich systems, particularly those that have symbolic representations, like DNA/RNA. Indeed, the ability of a medium to carry information is inversely proportional to the likelihood of it self-organizing. Not sure why this is lost on some self-organizing proponents. Thus, self-organization is, from a logical standpoint, inherently incompatible with the existence of complex specified information. Darwinism on the other hand is logically compatible with complex specified information in the sense that it is at least logically possible for chance changes plus some kind of filter to produce complex specified information. Unfortunately for Darwinism, there is no evidence that complex specified information in life came about this way, and indeed, the probabilities preclude this as a live possibility in our current universe. In summary, as an explanation for life: (i) self-organization is not logically possible; (ii) Darwinism is logically possible, just not actually possible.Eric Anderson

That leaves me wondering why he would have ever taken Darwinism to be a metaphysical system.
Because it is not based on actual science.Joe

We're all happy for his willingness to come out as a Darwin-doubter, but is believing in Self-Organizing Systems any better? How do you explain how matter gains the wisdom and ability to organize itself? Doe anyone see a problem here?tjguy
