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 The physicist Fred Hoyle famously said: The chance that higher life forms might have emerged in this way is comparable to the chance that a tornado sweeping through a junkyard might assemble a Boeing 747 from the materials therein. I agree with that assertion, but that conclusion can’t be formally derived from the 2nd law of thermodynamics (at least those forms of the 2nd law that are stated in many physics and engineering text Read More ›

Sal C has begun a series of UD posts on entropy, thermodynamics and info challenges. I have thought it important to highlight the macro-micro info gap issues underscored by Jaynes et al, and to raise the issue of spontaneously moving from Darwin’s Pond-state to cell-state (whether in increments or not does not materially affect the point) without intelligently directed organising work. This sets the context for the design inference on OOL, in light of the significance of our broad base of experience on the source of FSCO/I: Materials + Energy sources + IDOW –> FSCO/I Where FSCO/I is evident from functional specificity and complexity of organised entities. Such may also directly store information in physical data structures such as control Read More ›

The common belief is that adding disorder to a designed object will destroy the design (like a tornado passing through a city, to paraphrase Hoyle). Now if increasing entropy implies increasing disorder, creationists will often reason that “increasing entropy of an object will tend to destroy its design”. This essay will argue mathematically that this popular notion among creationists is wrong. The correct conception of these matters is far more nuanced and almost the opposite of (but not quite) what many creationists and IDists believe. Here is the more correct view of entropy’s relation to design (be it man-made or otherwise): 1. increasing entropy can increase the capacity for disorder, but it doesn’t necessitate disorder 2. increasing an object’s capacity Read More ›

In the next video for the Engineering and Metaphysics conference, we have our keynote speaker, Walter Bradley, author of The Mystery of Life’s Origin (the book which kicked off the Intelligent Design movement). Here Bradley presents an overview of the cosmological case for design. Lots of interesting information from the man who started it all! There are a few breaks in the video due to tape changes.

In Bejan’s “Design in Nature”, Bejan promotes what he calls the “constructal law,” which states, “For a finite-size system to persist in time (to live), it must evolve in such a way that it provides easier access to the imposed currents that flow through it.” Bejan has denied that this relates at all to any ultimate form of design, but is this claim correct? In our next Engineering and Metaphysics video, Halsmer and Odom look into the constructal law and whether it indicates design, as well as other, new aspects the constructal law might be applicable to.

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.”
