Science and Religion Part II


Did Lawrence Krauss really say that? Is Deism the thin end of the theist wedge?  Deism has been an exit point for faith, so perhaps it can also be an entry point? However, the second part of that statement looks as though it's there to keep the atheist gallery happy by signaling that Krauss  still has a gung-ho anti-religious stance. But I think he needs to brush up on just what theistic evolutionists are saying.

In his book The Blind Watchmaker, Richard Dawkins tells us:

Darwin made it possible to be an intellectually fulfilled atheist.

 (The Blind Watchmaker (1986), Chapter 1 “Explaining the Very Improbable” p. 6)

This view, I submit, is evidence of the Western Dualist paradigm which sees so-called natural forces and God's creative action as two very distinct and mutually exclusive modes of creation: For Richard it was an exclusive-OR between the "natural forces" of Darwinian processes and the supernatural power of God. But since Richard is an atheist he therefore votes for the natural forces party.

Western Dualism was historically expressed as deism; this is the view that God is to his created world as the skilled human artisan is to the automata of the 18th century. In both cases the created object is thought to have an animus of it's own, an animus by which it is able to function autonomously: Sci-fi stories where the created object runs out of the control of its creator tap into this paradigm. When pushed too hard deism leads to a creation cut adrift from its Creator and eventually death of God secularism: Somehow it is supposed that the cosmos is sufficiently self-provisioned to create and run itself. But as I've pointed out before the material of the cosmos has no property of aseity: The simple logic of the mathematical elementa of physics can't be the source of aseity: That logic necessarily starts with brute-fact contingencies, not aseity. In contrast, God being infinitely complex, could hide aseity in that complexity although we would be hard put to it to understand the infinite logic of aseity. Hence it is written: And without faith it is impossible to please God, because anyone who comes to him must believe that he exists and that he rewards those who earnestly seek him. (Hebrews 11:6). That verse is the axiomatic cornerstone of a successful epistemology in that it provides the template for its natural analogue: Viz: anyone who comes to the cosmos must believe that it is organised, coherent and rational and that it rewards those who earnestly seek that rationality. Without this epistemic assumption we move dangerously close to the nihilist abyss. But axiomatic belief that nature conforms to intelligible and ordered patterns of behavior doesn't necessarily entail a belief in the autonomous animus of nature or the connected idea that  if "natural forces did it God didn't do it!"

Is the axiomatic & metaphysical belief in the independent animus of nature right?  It seems that evangelical atheist PZ Myers thinks so; see the following comment which Myers posted in 2014. In this comment Myers is criticizing those evolutionists who seek common ground with "creationists" through theistic evolution, an approach Myers most definitely rejects...... 

Coyne also has some ire for the theistic evolutionist perspective, as well. So do I. I think it distorts the science in an ugly way. It’s effective with some soft creationists in the same way the approach I mentioned in the last paragraph works. You find common ground: “I believe in God, too!” Then, unfortunately, to bring them around to your side, what you then do is produce a mangled, false version of evolution — “It’s guided by a higher power!” — in order to get them to accept “evolution”. A gutless, mechanistically compromised version of evolution.

No thanks. Darwin’s great insight was that you don’t need an overseer guiding evolution — that local responses to the environment will produce efficient responses that will yield a pattern of descent and diversity and complexity. To replace “intent was unnecessary” with “God provided intent” does deep violence to the whole theory, and completely misses the point. (My emphases) 

And the point? The metaphysical idea of the animus of natural forces is clear here: Viz: you don’t need an overseer guiding evolution. The general notion here is that the physical laws are a kind of proactive guiding hand rather than a passive description of patterns of behavior sustained by God himself. 

But evolution as it is currently understood would not work without some kind of a priori information reservoir. See chapter 8 of this document where I discuss this question. It follows then that evolution isn't in fact a purely random process (something PZ Myers agrees with - see here). As such it displays a very constrained pattern of behavior; forget those claims about evolution being nothing but "randomness" because if standard evolution is to be viable any such randomness can only generate life if it is constrained within a very tight envelope defined by the natural physical regime - if this constraint didn't exist there would be no evolution. 

But for Myers the existence of those highly constrained patterns of behavior must mean that evolution has all it needs in terms of physical resources and therefore doesn't need any further input from deity.  Viz: Darwin’s great insight was that you don’t need an overseer guiding evolution.  For Myers somehow those very constrained patterns sustain themselves and have an intrinsic animus to do so. Well, that's understandable given his atheism; he's actually following in the footsteps of those deists who conceived that God was to nature's mechanisms as man was to his automata and therefore God can at least stand back if not take leave of absence altogether while nature performs according to its own inner drives. 

But for (non-deist) theists like myself, the origin and sustenance of those strange and very contingent laws of behavior can not be either self-created or self-sustaining; they require deity in constant attendance and therefore in that sense for Christian evolutionists God must be the ever-present and immanent "why" behind the "how". What justification does Myers have for claiming that theistic evolutionists have produced a mangled, false version of evolution..... a gutless, mechanistically compromised version of evolution.....To replace “intent was unnecessary” with “God provided intent” does deep violence to the whole theory, and completely misses the point? Just what violence is being done to the theory and what point is being missed?  Yes, to imagine that there is a God behind the scenes constantly creating, sustaining & managing natural patterns, patterns which have no aseity of their own will no doubt seem to Myers eccentric to the point of crankiness. But if he could humor the theistic evolutionists for a while he might then realize that their cranky extra-evolutionary obsession does no violence to the theory itself since it doesn't change the patterns of behavior or add anything observationally to them; they remain the same.  This also voids Krauss' criticism: There is no necessary internal inconsistency in theistic evolution because it doesn't necessarily change the observable evolutionary patterns of behavior. 

Theistic evolution is in fact a interpretation layered on top of the science and what does change is the intuitive opinion about the meaning of those patterns: Viz: For Myers his intuition is that we need look no further for explanation than in a very contingent natural pattern; for him those patterns are just brute facts and that is the end of the matter (See Bertrand Russell's opinion here which is analogous). But for theists like myself this leaves us with an empty and meaningless absurdity: In my opinion that absurdity can only be dispelled by the intuition that those patterns have an intentionality about them..... so it's all down to a difference in intuition. Although I have no strong commitment to affirming standard evolutionary mechanisms I find nothing absurd about theistic evolutionist's notion that God is the creative force in a standard evolutionary scenario.

In a post on Panda's Thumb, mathematician Jason Rosenhouse tells us about his book entitled "The Failures of Mathematical Anti-Evolutionism".  In his book he challenges anti-evolutionist's misuse of mathematical results such as the second law of thermodynamics, a law which fundamentalists and de-facto IDists never seem understand (Perhaps with one notable exception). But for reasons other than  his useful critique of anti-evolutionism the following paragraph by Rosenhouse is notable (In particular see the two sentences I've emboldened):

Sometimes the anti-evolutionists invoke a mathematical principle rather than carry out a calculation. They go on at length about the “No Free Lunch” (NFL) theorems, for example. These are legitimate mathematical results that establish the non-existence of a universally successful search algorithm. Dembski, sometimes with various coauthors, has argued that since evolution is in some way analogous to a combinatorial search, these theorems imply that any success that it has can only result from intelligent tailoring of nature’s fitness landscapes to the “algorithm” of natural selection. But once again the theorem plays only a rhetorical role in the argument. Since nature’s fitness landscapes arise ultimately from the laws of physics, Dembski and his collaborators are really just asking why the universe has just the properties it does. It’s a reasonable question, but it’s not one biologists need to worry about, and it’s not one to which the NFL theorems make any contribution toward answering.

(Note: What Rosenhouse refers to as the Fitness Landscape I refer to as  The Spongeam). 

Rosenhouse's comment at the end here is comparable to one made by mathematical biologist Joe Felsenstein (See below); namely, that the a priori information content demanded by standard model evolutionary mechanisms is found in the fitness landscape and this information in turn must be implicit in the physical regime. ID guru William Dembski drew attention to the fact that this a priori information must be present somewhere. But what Dembski did not show was that this information wasn't present in someway in the physical regime. He more or less admitted as such in this lecture.  De facto IDists misused NFL theory in that it was assumed by many of them with dualist habits of mind to imply that natural forces in the form of evolutionary mechanisms had been eliminated from the inquiry - in fact those proposed mechanisms were still very much part of the inquiry.  As Felsenstein said in a comment on this blog post of mine

If the laws of physics are what is responsible for fitness surfaces having "a huge amount of information" and being "very rare object[s]" then Dembski has not proven a need for Intelligent Design to be involved. I have not of course proven that ordinary physics and chemistry is responsible for the details of life -- the point is that Dembski has not proven that they aren't.

The question of direct Intelligent Design thus shifts from ad-hoc paranormal interventions to the origins of the contingent information implicit in the cosmic physical regime; it is this, according to Felsenstein, which has made standard evolutionary mechanisms  possible. As Felsenstein went on to say:

Biologists want to know whether normal evolutionary processes account for the adaptations we see in life. If they are told that our universe's laws of physics are special, biologists will probably decide to leave that debate to cosmologists, or maybe to theologians.

Now there's a challenge for the theologians! As with the quote from Lawrence Krauss we see a crack in the wall of atheism through which light is streaming!

So, the conclusion is that whether or not life has arisen via standard evolutionary mechanisms, either way we talking about Hard Creationism in so far as a huge reservoir of a priori contingent information is required to resource creation and in particular evolutionary mechanisms.  But the hardened atheist response is unlikely to concur even with Krauss's admission that because the universe is an amazing place then deism isn't an implausible postulate. To neutralize any amazement about cosmic contingency some kind of multiverse is often resorted to. Multiverse postulates are intended to reduce the surprisal value of our information rich universe to the level of trivial expectation by placing it in an all but infinite sea of pure randomness.

The Western deist response, which at least gives a starting role to God (but thence forth God is retired from the scene), partly has its origins in a reaction to the automata of the enlightenment. But for myself I think it likely that the information input from deity is on-going and not a once-for-all act.

Brian Cox on The Cosmic Perspective

Brian Cox's "Sunset of Mankind"*

Brian Cox: The contemporary (and in the last analysis, nihilist)
 guide to the Cosmic Perspective

According to my reading of Brian Cox's Wiki page he's not an outright atheist which I suppose makes him agnostic. He always comes over as Mr. Nice Guy, completely genuine in his atheism agnosticism. For me he challenges the Christian fundamentalist tendency to use Romans 1:18ff as an indictment on outgroups, sometimes as a pretext to accuse them of suppressing the truth in their wickedness. That, I believe, is not true of Brian Cox; he's entirely genuine in his expression of what I would identify as his resigned nihilistic world view. Let's remember that Romans 1 was written in Roman times and was addressing a very different cultural landscape of myriad minor gods and contrasting it with Judeo-Christianity's strict monotheistic creationism.

In Brian's latest series, Universe, he does his best to wring out some kind of meaning & comfort from his depiction of an eons long cosmic history that ends in the absurdity of meaninglessness and darkness. From my perspective the story Brian tells, although intriguing & aesthetic, has a denouement that is dreary and devoid of eternal hope. He charts the relatively brief flicker of human civilization which according to Brian must, in the vast expanse of cosmic time, ultimately be snuffed out like a candle and forgotten. Brian might be agnostic but really his is an atheistic view of the cosmos which gives no cognizance to the theistic possibilities of agnosticism; in fact I would go as far as to say it is not unlike H. G. Wells' nihilistic vision of the destiny of human civilization we find in Wells' book "The Time Machine". 

However, I wish there were more affable atheists and agnostics around like Brian. Ironically, I feel I have more in common with his epistemic attitudes than I do with vociferous fundamentalists like Ken Ham.

In the following interleave format I provide a selection of Brian's comments around the subject of meaning that I found in the first episode of his Universe series. This isn't a verbatim transcript and it's highly selective in its quotes.

***

Brian: There are 200 billion stars in our Galaxy and 2 trillion Galaxies in the universe.

My Comment: Breath taking statistics in one sense, but in terms of the computational resources needed to create living complexity those stats are actually quite miniscule. Take the logarithm of those figures and you end up with small numbers. 

Brian: The universe is vast, terrifying and incomprehensible. It's only natural for us live out our lives oblivious of it. There are two perspectives: We are grains of sand adrift in an infinite indifferent ocean or nature's most magnificent creation.

My Comment: Yes, Brian's right, the Universe is vast, terrifying and incomprehensible. It's incomprehensible because on the face of it is devoid of anthropic significance & relevance, an utterly anti-anthropic enigma to average opinion; better to remain abstracted by commonplace necessities!  And yes, Christian theists have been hard put to it to make full sense of it all since the demise of the Ptolemaic Solar System. As for the two perspectives, I'll vote for the second perspective; the human organism is a magnificent creation, an informational miracle, an organized material contingency of unparalleled surprisal and completely unwarranted by any logic known to man.  If the configurations of life really were the result of a mere random selection you could search all the grains of dust across the visible universe and not find an example of life.

Brian: The story of the cosmos is surely the greatest story ever told. 

My Comment: Certainly a great story but not quite the greatest story in my opinion. The greatest story is the the revelation of the story of salvation (Philippians 2:1-11). 

Brian: The Sun has created the things which brings meaning to the cosmos - life & human beings. Ancient cultures deified the Sun. 

My Comment: The traditional deification of the Sun is seen here to have a metaphorical truth. This metaphor recognizes that without the Sun life wouldn't happen.  The prehistoric agriculturalists understood the importance of the Sun and the cycles of the heavens. Not surprisingly then, they saw those cycles as having divine significance.  It is this tendency to deify the heavens (and nature) that Genesis 1 tries to head-off

Brian: Far back at the beginning gravity began to sculpt the universe in hydrogen and helium. The thing that brings meaning to the universe is life and life is just complex chemistry.  The Sun had power to turn planets into worlds. Quite by chance the earth formed. 

My Comment: In this first episode of Universe Brian repeats more than once his view that he sees meaning exclusively intrinsic to the very ephemeral appearance of life; nowhere else is meaning to be found. If the chances he talks of failed to bring about the existence of life then there would be no meaning; in Brian's world meaning is captive to chance. Brian uses that emotionally loaded word "just"; Viz: "life is just complex chemistry".  But given that this chemistry, if appropriately configured, generates the conscious first person perspective there is no "just" about it far as I'm concerned; this is a highly anthropocentric feature of matter. Chemistry has been miraculously provisioned to generate consciousness, if used rightly. The human mind is more than the third person perspective, a perspective which is bound to only see the first person perspective as a complex organization of interacting particles (i.e. chemistry). 

Brian: How can the complexity of life emerge completely naturally in the universe: It's the huge temperature difference between the Sun and the cold of space which creates life. This temperature difference allows for the building of complexity.  Life is miraculous! 

My Comment:  In talking about life emerging "completely naturally" I guess Brian is thinking of its emergence being sufficiently provisioned by the natural laws of physics. The extremely low entropy of the Hot Sun/Cold Space temperature difference is exploited by those laws to create the low entropy configurations of life. Many naïve Christian young earthists still falsely believe the second law of thermodynamics is an outright barrier to the emergence of life, not realizing that entropy is a crude parameter which only measures the statistical weight of a total system. Entropy is an extensive rather than an intensive variable and therefore given that the 2nd law only pertains to this extensive variable it is not in-and-of-itself sufficient condition to rule out the possibility of increases in order in localized pockets of the system; the second law only tells us about the inevitably increasing statistical weight of the whole system. Crystal formation is a simple case in point: Crystal formation entails a considerable local increase in order although the overall system in which crystals are formed increases in entropy. 

To be fair, however, life in its complexity of organization is a very different kettle of fish to simple crystals. But to prove that localized increases in order can't happen and that life can't evolve requires a much more thorough understanding of the implications of the natural physical regime and whether it allows for the probable existence of localized pockets of complex organisation. In particular there is neither proof nor disproof of the mathematical existence of the spongeam, the necessary condition for evolution. The spongeam is a structure in configuration space that considerably constrains the random diffusive dynamic of conventional evolution. This structure entails an overall increase in entropy with time and yet pockets of complex order may be permitted if the channels of the spongeam funnel evolutionary migration through regions of complex order.  But at least one fundamentalist seems to have twigged that the analytical difficulties here are such that he has advised the 2nd law not be used as a way of trying to refute evolution. 

Brian rightly sees life as a miracle. But in what sense does he see it as a miracle? Is he aware that any physical system which generates life in a relatively short cosmic time must have a miracle of contingency at its heart? (See here for more)

Brian: We exist because of the sun. We don't need to invent imaginary gods to explain the universe. We can replace them with the real thing; everything has been created and crafted  by stars. 

My Comment:  This really does look like the sort of thing an atheist would say.  It also looks like the classic exclusive-OR of dualism, that is, the "God did it" or "natural forces did it" paradigm where the suggestion is that if it's one then it's not the other. I criticize this false dualism more fully here

Brian: But dark will eventually descend as the stars fade. Red dwarfs like Trappist-1 (already 7 billion years old)  will, 5 billion years from now, see our Sun flicker and fade way forever. The death of the Sun is just one of many and cosmically speaking is an inconsequential event. But it would be the end of a glorious time of art, music, poetry and science and that does matter. The fragility of our lives makes them valuable. 

My Comment: But valuable only to us, otherwise, according to Brian, our lives are of no significant import in the wider cosmic context.  

Brian's prognostications here are very reminiscent of H. G. Wells' The Time Machine a story which contrasts the halcyon days of human civilization with its eventual & inevitable demise when seen  in the big picture. The Sunset of Mankind, Wells called it in his chapter 6. The above is Brian's Sunset of Mankind. His quoting a glorious time of art, music, poetry and science  is a bit one sided though: The history of humanity includes many, many brutally ugly injustices & sins, injustices & sins that will never be called to account & settled according to Brian's Sunset picture (Or Wells' picture for that matter). 

Brian: In 10 trillion years the last star (which will be a red dwarf) will fade. The universe becomes a void without light, life or meaning. The darkness will last forever. As the stars fade so does all possibility of  life and meaning. The stars illuminated the dark and allowed us to illuminate it too. 

My Comment: The anti-climax to end all anti-climaxes!  Brian is asking us to gain some comfort from the idea that we are, or rather were, a tiny island of meaning which is eventually and inevitably swallowed up by the dark abyssal deep of chaos (See Genesis 1:2). The kaoskampf ends in defeat for humanity on this account. If Brian is agnostic and caught between atheism and theism he's not giving much space to the possibilities of theism. Perhaps he's hoping for a revelation and a ray of light to break through the gloom.  That, we can only leave in the hands of the Almighty Himself. 

***

Notice that in order to sketch out his grim prognostication for humanity Brian has assumed it's just a case of extrapolating the laws of physics far into the future. But there is an asymmetry between past a future: The past provides us with observational evidence of itself in terms of the signals it sends us; a consequence of increasing entropy. There are no such signals and therefore no such observations to be made of the future. See this book where I take up this question with a Genesis 1 literalist & fundamentalist who thinks that for scientists reconstructing the past is just a case of back-extrapolation rather than of observation and therefore treats the past and future symmetrically and as equally speculative.
