We need not specify God's relative complexityThat's not quite true, Doctor B. While stupid engineers can create more sophisticated computers, this is precisely because they enjoy the benefits of a long and rich cultural inheritance, of advancing technology and scientific understanding, thus requiring them to generate very little innovation at any given step.
153. Comment #72971 by Dr Benway on September 23, 2007 at 4:41 pm
A pre-universal, singular deity does not enjoy this benefit, and must necessarily be tremendously more complex than anything it may create, precisely because anything it devises, it devises on its own, in a single 'generation'.I believe God must be more complex than His creation. But I haven't pondered the matter long enough to feel confident of my belief.

Quine (post 123, or #72723):If you read the whole section you will see that RD has not made the case that the anthropic principle implies naturalism, but just allows it (i.e. removes counter argument).If the counter argument is that the probability of a naturalistic origin of life is less than 1/10^40000 then it does nothing of the sort. I really cannot see why Dawkins would not mention that probability estimate and try to show why it is fallacious, but would rather bring in the fairly irrelevant issue of the anthropic principle and that there are a "billion billion" planets in the universe and whatnot, except if a) he is himself really confused, or b) he tries to confuse his readers.
He does, also, spend some time arguing that the anthropic principle is misused by religious apologists against naturalism.I am not aware that theists use the anthropic principle in relation to the problem of how the first self-replicating organism came into being, but I may be wrong. I mean there are a lot of fallacious arguments around. As for the anthropic principle it just states the obvious: reality must be so as to produce all the evidence we have. To call it "anthropic" is a misnomer; after all reality must be so as to produce comets, or as to produce rock-n-roll music (so one might have called it the "cometic principle" or the "rock-n-rollish principle"). The idea has nothing to do specifically with the origin of human life.

There is a bit about this in post 108Ooh, I hadn't read this one. Maybe I'll respond to it while you
You know, like "rain comes from the clouds, music comes from the loudspeaker, so God must be coming from somewhere too". No wonder more thoughtful atheists felt embarrassed with TGD.I don't see why issues of causality would be unimpressive to a 'thoughtful' atheist. You can't satisfyingly and validly end problems of causation by asserting the existence of something somehow "uncreated", when by our only measure of causality the Big Bang itself is uncreated (it has no measurable cause because the local measure for causality, time, was included in the event), and this rightly has failed to satisfy our curiosity. If we are going to postulate extra-universal dimensions from which things can cause other things with their own local measurements, and we refer to the former as a cause, there are no grounds to conclude that our explanation has ended - we've just postulated that our time isn't the only measure of causality, so why should it stop there?
Don't naturalists of all stripes define the universe to be "self creating" at the Big Bang?Naturalists do not define the Universe as being a self, because it's development is one of non-conscious, interacting elements. They do not refer to stars as 'self creating' through the 'third-person' force of gravity, and they do not refer to species as 'self-creating' in response to external Darwinian selection, probably because that is such a stupid and meaningless way of putting it.
160. Comment #73054 by Dianelos Georgoudis on September 24, 2007 at 2:03 am
Coel (post 137, or #72823):Oh, come on. Dawkins discusses plenty of entirely spurious claims in TGD, and to good effect. If he thought that Hoyle's number is entirely spurious he would have demolished it. The fact that he didn't even mention the number, and much less tried to argue that it's fallacious, shows that Dawkins did not know how to do it. Hoyle is a Nobel level scientist you know, and here he is writing about a scientific matter. I think it's rather unlikely that his claim is "entirely spurious".Hoyle estimated that the probability for obtaining naturalistically the required set of enzymes for even the simples living cell (required for Darwinian evolution to start) was 1 in 10^40000. [. . .] Of course [Dawkins] never mentions how improbable that is supposed to be, I supposehe did not want to trouble his readers with estimates like 1/10^40000.The reason he doesn't discuss Hoyle's number is that it is entirely spurious.
The initial replicator would have been far simpler than that.That's what I too argued in post 132 above, and it's what Dawkins should have argued in TGD. But he didn't. Dawkins has done some work on the origin of life, so I can hardly assume that he was not aware of our simple argument. What I assume happens is that even concentrating on the idea of the simplest possible self-replicating organism nobody has been able to come up with a larger probability estimate that would make any difference in practice. To falsify Hoyle one should be able to build an argument (without begging the question of course) that the probability of the first self-replicating organism is larger than 1/10^50; anything bellow that would still be "impossible" for all practical purposes.
So of course the first replicator was not a whole cell; it was more likely just a molecule. Maybe it was a RNA polymerase ribozyme. SeeA replicating molecule by itself is not sufficient; you need a replicating organism that has the properties necessary for Darwinian evolution to take hold, and it seems to me that the RNA molecule by itself does not fit the bill. But suppose I am wrong and that it does. Then how probable is its spontaneous appearance of RNA anywhere in the universe? After all RNA is as complex as DNA. But my basic point is this: Dawkins certainly knows much more about this stuff than I, and he is demonstrably able to explain to a popular audience even complex and subtle ideas. Why should then I (or we) speculate here? Why didn't Dawkins himself in TGD explain on scientific grounds where Hoyle is wrong and why the naturalistic origin of life is a plausible hypothesis? The only answer I can think of is: because he did not know of any such scientific grounds. Which, again, is OK with science, but is not OK with Dawkin's project to show how trivially wrong theism is.
http://www-ssrl.slac.stanford.edu/research/highlights_archive/ligase.html
Dawkins's use of the anthropic principle here is entirely sensible and valid. He is saying that, yes, even the spontaneous assembly of a self-replicating RNA molecule is very likely highly improbable. But so what? It being highly improbable is amply good enough. Even if it had such a low probability of occurring that it had only a 1-in-a-billion chance of occurring in a wait of 1 billion years in a `testube' the size of the Pacific Ocean, that is still probable enough because there are a billion planets with billions of years each available.I am sorry Coel, but it seems to me you are dancing around the issue here. "Very likely highly improbable" means nothing at all and is a smokescreen in its own right. If the probability of the RNA molecule is anything like 1/10^40000 then it would not be probable to rise in a billion billion billion billion billion planets in a billion billion billion billion billion years. The facts are that Hoyle has claimed the 1/10^40000 number based on some scientific thinking, and Dawkins has written nothing in TGD to dispute that number he didn't even mention it.
161. Comment #73056 by Dianelos Georgoudis on September 24, 2007 at 2:14 am
Dr Benway (post 148, or #72906):Right. What do you think about the naturalist's stance who held that naturalism is not falsifiable (see post 142)? For example, if you actually experienced what you describe above, with scientific congresses going nuts, newspapers discussing that surprising phenomenon on their front pages for months, and so on, and then somebody came out and suggested that some alien race with a technology so far more advanced than ours as to be able to do what to us looks like magic must be playing games with us, wouldn't you find that explanation more reasonable than the explanation that the God as described in the Bible actually exists? Come to think of it, I think I would.Also in this context I wonder: what evidence would be sufficient for you?Can I play? How about: 1. Autopsy of all deaths this day forward reveals the words, "Yahweh here. Yes it's all true. Read your Bible!" inscribed on each femur.
Don't rebut me with my own point.Oops, you're right I did that, sorry. But then why did you write up in post 114 a good analogy for Dawkins's argument and then rebut it yourself in that same post? As you write the analogy works only "if naturalism is true", so you actually illustrate that Dawkins is begging the question which has been my main point all along.

If the probability of the RNA molecule is anything like 1/10^40000 then it would not be probable to rise in a billion billion billion billion billion planets in a billion billion billion billion billion years.I'm not a statistician or astrophysicist ot cosmologist, but in my wonderfully naive way, isn't the probability of life emerging spontaneously at some point in the universe actually 1? I mean, even with hoyles number of chance, think of the trillions and trillions of planets and trillions and trillions of galaxies that have existed over time. Our universe could be many googles older than what we can observe, its just that right now we can only see to about 15GA. So even by that stretch of the non-scientific mind, i can certainly see that the chance of life existing spontaneously is even with that small number, a pretty sure bet.

165. Comment #73084 by Dianelos Georgoudis on September 24, 2007 at 4:16 am
Robert Maynard (post 149, or #72909):The important point to make is that there is no ex nihilo design in nature [snip]My understanding of traditional theism's "creation ex nihilo" is that God created the material universe out of nothing in the sense that God first created physical space and time and matter themselves, and that these things did not exist previous to God's creative act. But I am not sure that traditional theism claims that design in nature was ex nihilo too. Obviously "design" is a mental concept, and I suppose a traditional theist would argue that the design in nature (physical laws, the species, you name it) was not ex nihilo but rather represents order that God's intelligence imposed on the already existing physical space, time and matter.
[cont] and all design work in nature takes place from a darwinian perspective, as a cumulative process of algorithmic selection from a pool of random variation.Agreed. Indeed many theists agree with that. But it's important to note that Darwinian evolution does not contradict the thesis that God designed the species; that's just a logical fallacy that many people (both naturalists and theists) commit. In short the proposition "The complexity of the species can be explained through Darwinian evolution" does not imply "God did not design the species". If you think otherwise I invite you to present an argument for how the former implies the latter. I think you'll see that the former proposition only implies the falsity of Biblical literalism and the belief that, for example, God first built some man-sized doll out of clay and then blew air in its nostrils and lo and behold the doll became Adam.
We must credit human inventions all the way back to a point where we must begin crediting Darwinian selective pressures which gave us the cognitive prowess and the dexterous physiology required to develop tools.Well, just a moment :-) Are you sure you are not here changing the meaning of the concept "personal design", or if you prefer "intentional design"? I mean let's take some example of such design, say von Neumann creating the design of modern computers, or Beethoven creating some of his sonatas, or the Los Alamos crew creating the first atom bomb. Are you saying that it's not really they that did the designing, but rather they and all their ancestors including prokaryotic bacteria of 2.5 billion years ago? Because if you do, that's not the meaning of the word "design" as normally used, and I don't think that's Dawkins's meaning either. After all Dawkins in page 31 of TGD defines the God hypothesis thus: "There exists a superhuman, supernatural intelligence who deliberately designed and created the universe and everything in it, including us." That hypothesis says nothing about what that intelligence consists of or about its origin, except that that intelligence designed the universe we observe around us and everything in it. So the God hypothesis, as defined by Dawkins, allows for that designing intelligence to have evolved by some means too. As a matter of fact it allows for that intelligence to be some kind of alien race living in some unknown world where they have the capability of designing and creating universes like ours (an idea from Sagan's "Contact"). Dawkins thinks it's easy to show that all such possibilities are "almost certainly" false. He believes that it's almost certainly true that we are not designed by any intentional agency and that's that. (It is in the context of justifying this thesis that he uses, without justification, the premise that an intentional designer must be at least as complex as what he/she/it designs. And that's the claim I am here disputing. And to dispute that I can very well point out potential examples of intentional design, whether driven by one person or a group of persons, where what's designed is more complex then the designer(s)).
In order to know and plan the continuity of the Universe, one must possess the cognitive complexity to be capable of representing the entire causal history of this universe as simulation. Beyond the stuff of physics, this requires predictive knowledge of every cognitive agent, that's including (but not limited to) the mind of every human that will ever live. The complexity required to conceive of this complexity far exceeds the complexity being conceived. Even if we were to restrict or entirely remove complete foreknowledge from our hypothetical deity's 'abilities', the computational complexity required to observe every variable in the universe in a single instance exceeds the complexity IN the universe by many orders of magnitude. Omega of story. :PWhy do you think that a being of sufficient cognitive ability to design the universe should be very complex (let's leave aside the stronger "more complex than the universe" issue). Why exactly must an intelligent being be complex? I know it appears to be obvious, but have you considered why it appears to be so? Because we are used to thinking naturalistically, i.e. thinking in terms of machines and their capabilities. So we imagine that a mind powerful enough to design the universe must be some kind of frightfully complex brain, having many parts and bits and pieces all working together in a precisely choreographed manner. But I trust you see that this kind of thinking is contingent on the truth of naturalism; it takes naturalism's view of reality and projects it on the theistic view of reality. If naturalism is not true then there is no reason whatsoever why a powerful mind must be complex. But to implicitly assume naturalism while countering theism is, once again, to beg the question.

Robert Maynard (post 153, or #72923):Learning involves perceiving new observations, or through reflection, building on prior observations. If a deity could "learn" how to create a universe, what precisely was it observing and reflecting upon when it did so?Maybe, some other toy universe that deity created before ours. Why not? Some naturalists seriously think that we may all exist in a computer simulation (see www.simulation-argument.com ). I mean the possibilities for a superhuman learning designer are infinite; use your imagination. Dawkins in TGD claims that all these designers of our universe "almost certainly" do not exist.

173. Comment #73355 by Robert Maynard on September 24, 2007 at 8:29 pm
Are you sure you are not here changing the meaning of the concept "personal design", or if you prefer "intentional design"? Are you saying that it's not really they that did the designing, but rather they and all their ancestors including prokaryotic bacteria of 2.5 billion years ago?Well, no, because if you kept reading you would see the line "Were [our prokaryotic ancestors] mindlessly reproducing with that end in mind?" I was implying "no", which you'd know if you had read the next line. "That's not design, bub".
So the God hypothesis, as defined by Dawkins, allows for that designing intelligence to have evolved by some means too. As a matter of fact it allows for that intelligence to be some kind of alien race living in some unknown world where they have the capability of designing and creating universes like ours.It says "supernatural". Did.. did you miss that? Because there's a word in the phrase "natural selection" which doesn't mix with a word meaning "above nature". I don't know what else to say to that..
The existence of the physical universe as understood by naturalism is not a given; what is given is our experience of the phenomenal universe. And a complex (i.e. "brain-like") mind able to produce/simulate that experience for all of us turns out to be several orders of magnitude less complex than the simplest naturalistic description of the universeI'm not clear on what you're saying here. Is it -
174. Comment #73370 by Dianelos Georgoudis on September 24, 2007 at 10:10 pm
Janus (post 154, or #72930):Well, yes and no. After all if the designer is much simpler it's not quite clear why it requires an explanation. In fact it's not even clear why an explanation of an explanation is required in any case. For example Einstein's general relativity hypothesis that mass bends spacetime in a particular manner is a powerful explanation for a series of phenomena; but it hardly makes any sense to ask: "But how do you explain that mass bends spacetime in this way?" Or, rather, whether that latter question is meaningful or not, and if it is whether one has an answer or not, does not in any way weaken general relativity's explanatory power. Now, before you argue that contrary to general relativity the God hypothesis does not explain anything let me point out that in our context that's irrelevant, because Dawkins is not arguing that the God hypothesis is wrong because it does not explain anything but because there is not a further explanation for it. In short he is asking: "If the existence of a designing God is the best explanation for the existence of the universe then what explains the existence of God?" But apart from the very bad logic behind that question, it turns out it admits a simple answer: "I don't know what explains the existence of God, but the existence of God is still the best explanation for the existence of the universe".Here is what he writes on page 109: "A designer God cannot be used to explain organized complexity because any God capable of designing anything would have to be complex enough to demand the same kind of explanation in his own right".Dawkins' statement is valid whether or not it's true that a designer must be at least as complex as the thing he designed.
Neither I nor Dawkins claim that because "we know of no irrefutable objections to the claim that the universe is comprehensible" therefore it is comprehensible.Well, when you wrote "We have to assume that the universe is comprehensible as long as there remains a possibility that it is" it sounded to me like you meant that, but now you clarify I misunderstood you.
What [Dawkins and I] do claim is that if our goal is to explain order and complexity in general (whether it's life or the laws of physics or anything else), the ultimate explanation for order and complexity cannot be something that is ordered and complex.Why not? Certainly Einstein's general relativity is both ordered and complex, and I don't see any reason why it can't therefore be the "ultimate explanation" for the phenomena it describes.
I don't think that Dawkins has ever said or implied that intelligence, complexity, and improbability are equivalent.I meant "equivalent" in the sense of "closely related". And his 747 argument makes little sense without assuming that he believes that the more intelligent something is the more complex, and the more complex the more improbable. But he justifies neither. What's more had he justified that in the physical universe and in some particular sense of "complex" it's true that the more complex the more improbable, it would be still be question begging to apply this premise beyond naturalism's concept of reality.
This reminds me of the following argument: "'Exists physically' is redundant. To say something exists is to say it exists physically. God is not supposed by theists to be a physical thing. Therefore God does not exist." :-) You see where I am driving at? In fact "to exist" does not mean "to exist physically", and "comprehensible" does not mean "comprehensible naturalistically". To change these words' meaning in this sense is the most clear case of question begging I know. Consider that by doing such you are only manipulating yourself into dogmatism. Dogmatism, by the way, does not characterize those who are too confident in their beliefs; after all nobody accuses mathematicians of dogmatism. Dogmatism is the loss of cognitive flexibility, the loss of freedom of thought. It's about losing the ability to actually consider or grasp what the other person is saying.You mean comprehensible naturalistically.No, I mean comprehensible. "Comprehensible naturalistically" is redundant. To say that the universe is natural is to say that it is comprehensible.
If you disagree with me, here's an easy way to prove me wrong: Give me one example of a supernatural "explanation" which doesn't amount to giving up on explaining complexity and order.Well, I don't want to divert this discussion from TGD to my own ontological views, but I think it's pretty easy to answer your question: I don't want to give up trying to explain the subjective part of my experience of life, indeed I don't want to give up trying to explain the huge fact that I am a conscious being in the first place. I find that naturalism fails to explain consciousness, because there is absolutely no reason why a material system should become conscious: there is absolutely no objective evidence (or physical phenomenon) that requires the consciousness hypothesis, therefore no reasoning based on naturalism's epistemology (the so-called "methodological naturalism") can possibly explain consciousness. On the other hand theistic thinking can explain consciousness. As it does explain a huge number of things related to consciousness, including why we experience a physical environment, why we experience natural and moral evil, why love feels like it does, why we possess intentional will, the meaning of beauty, the meaning of death, why there is (or at least appears) not to be any physical evidence for God, why living is so ethically challenging, how come objective morality exists, and so on and so forth.
[The fine-tuning of the fundamental constants] is not a difficult problem for naturalism, it's a difficult problem for the human intellect.Or to be more exact: a difficult problem for the intellect of those humans who believe in naturalism. You do see that the fine-tuning of the fundamental constants does not represent any difficulty whatsoever for the intellect of theists.
Fine-tuning can either be explained by science, or it can't be explained at all.It's a common naturalistic fallacy to believe that science is there to solve naturalism's problem. Fine-tuning is not a scientific problem; science creates models of phenomena and these constants are part of these models, so they are part of what science so successfully does. It's naturalism with its belief that science not only explains phenomena but also describes reality that must explain how come reality is so fine-tuned for life.
Where? Maybe you believe that consciousness, even though entirely unnecessary for explaining any physical phenomenon, is a scientific problem too? That's another fallacy, indeed one that many scientists commit also. But nothing fails like failure.Another extremely hard and purely naturalistic problem is consciousness.See above.
So the creation by us of what is arguably the most momentous technological achievement possible will have no designer at all? That's not how most people understand the concept of "designer". And you see where I am driving at: How a designer brings about some creation is irrelevant. That God created the species through something as smart and beautiful as natural evolution only makes me marvel even more at God's intelligence.If somebody writes a program using evolutionary algorithms (i.e. algorithms that mimic natural evolution), and that program finally achieves to create an intelligent program that passes the Turing test (i.e. displays human-like intelligence), then who is the designer?No one, the programmer would have figured out how to mimic evolution, but evolution would have shaped this new intelligence.

Robert Maynard (post 158, or #72976):If the Universe as it exists is the result of intent, I can't imagine how different it might look if it was the result of naturally emerging laws and forces.Well, there are many ways to answer this. The easy answer would be to point at the fundamental physical constants and argue that they evidence intent. A better answer though is to point out that any naturalistic universe would lack phenomenal consciousness. A naturalistic universe (with its fine-tuned constants) would evolve life, and intelligence, and culture, and finally philosophical discussions about consciousness, but would not have any actual consciousness in it. Dawkins's own meme theory can explain how a human brain without the capacity for conscious experience could produce philosophical arguments about consciousness. After all meme theory can explain all intelligent behavior without recourse to the presence of consciousness.

I personally believe that there is a naturalistic explanation for the origin of life.Eh? Like, now I'm totally confused!
the smartest stance naturalists can assume vis-a-vis people using the argument from design is: "Science does not yet know how life started, but it's working on it . it may take a while; this may turn out to be a very hard problem. If you in the meanwhile prefer to believe that the best explanation for the appearance of life is to posit some supernatural action then be my guest."Seriously though, why?

Robert Maynard (post 166, or #73057):This discusses problems in abiogenesis probability calculations.Thanks for the link. I am not qualified to judge the particulars (even though others have pointed at some mathematical errors in his reasoning), but I think what Ian Musgrave there does is on the right track, namely to take Hoyle's scientific claim and try to counter it on scientific grounds. But that's not what Dawkins in TGD did. So my argument stands: Dawkins starts his "central" chapter 4 by claiming that Fred Hoyle's claim of the improbability of life is spurious but then proceeds to counter Hoyle's claim using not science but an apparently very weak philosophical argument (his "ultimate Boeing 747") and then toping it all with the question begging issue of the "planetary version of the anthropic principle". Why would Dawkins fail to respond on scientific grounds unless he didn't know how?

If we don't currently know 'exactly' how abiogenesis can take place, and all the factors involved, it should be simple to reason that such calculations are based on shaky premises to begin with.

Coel (post 169, or #73079):Oh, for example the its replicating fidelity should be neither too precise nor too error-prone. Natural evolution takes hold only if there are replication errors but not too many. Also, while discussing the probability of life taking hold on a planet it's in fact an error to only consider the probability of the appearance of the first evolutionary viable replicating organism; for natural evolution to take hold that organism must find itself in the appropriate environment too, so the probability of that must be taken into account also. In fact Dawkins commits a slight technical error on page 135 when he writes "The origin of life only had to happen once". The appearance of the first viable self-replicating organism must have happened at least once of course, but maybe the conditions of our universe are such that a viable self-replicating organism must independently come into being billions of times before a viable process of natural evolution takes hold somewhere. (For roughly the same reason that not any one spark can put a forest ablaze.)A replicating molecule by itself is not sufficient; you need a replicating organism that has the properties necessary for Darwinian evolution to take holdWhat other property other than self-replication do you think is required?
I doubt that just one molecule can be alive, in the sense of being a viable organism that can start natural evolution. You mention "The Blind Watchmaker"; it's a long time since I read that book but I doubt Dawkins claims that much there. Self-replicating molecules probably played some role in the process that resulted in the appearance of the first viable organism, but I am pretty positive that the molecules themselves did not fit the bill.Then how probable is its spontaneous appearance of RNA anywhere in the universe?I honestly don't know, but it sure as hell is not Hoyle's number (which is not for one molecule but instead for the vast number of specific, interacting molecules in a highly complex, highly evolved modern cell).
Hoyle's number is based on the utterly unfounded idea [snip]I keep reading expressions such us "utterly spurious", "utterly unfounded", and so on. So why then did Dawkins fail to show that on scientific grounds in TGD? He did discuss Hoyle's probability estimate you know (he just did not print the actual number).

Lauregon (post 175, or #73182):It means that how it is like to experience life is directly caused by God and cannot be understood on any mechanical (read naturalistic) principles. Rather the subjective part of our experiential life can only be understood on intentional (read spiritual) principles. Not to put a fine point on it: when you see something that strikes you as beautiful you are seeing a reflection of God's objective beauty. You don't have to agree with any of these of course, but that's what I mean.(I believe that God interacts with us in the non-objective part of our experiential life but that's another issue.) - DianelosWhat exactly does that mean?
please explain what you see as the proper response and relationship of humans to the "God" you believe in.To try to become more similar to how God is, and hence to come closer to God.

Alovrin (post 177, or #73307):Your reading of The God Delusion seems to be coloured by the fact you think, said god exists.... somewhere.You may well be right; perhaps it's psychologically impossible to think about what other people say about reality in a way that is completely neutral to how one thinks about reality. But I try not to let my own preconceptions color my criticism of the book. So when I show that somewhere Dawkins is committing a fallacy (more often than not the fallacy of begging the question) I am not myself begging the question. That is, I am not saying "Theism is true and therefore Dawkins is wrong in what he says there", but rather "Dawkins there assumes that naturalism is true, which in the context of arguing that theism is false amounts to begging the question". There is big difference. After all it's a criticism a naturalist too might have made, and indeed a criticism that some well known naturalists such as Nagel and Orr have made (see post 85 above)
So this would seem to invalidate a lot of your criticism, as you would be unwilling to accept the premise of the book.If you mean that the premise of the book is that naturalism is true, then you are right that I am unwilling to accept it. Neither should I accept it. If Dawkins wants to show that the there "almost certainly" is no God he must not use as premise that "almost certainly" naturalism is true. Why not? Because naturalism means precisely that there are no supernatural powers such as God, so if Dawkins does the above he is basically writing an entire book to sell the tautology that as there is almost certainly no God, there is almost certainly no God. Which is true, but also a trivially true argument that carries no weight whatsoever. A theist could equally well write a book arguing that as there almost certainly is a God, there almost certainly is a God. Makes no sense whatsoever.

Robert Maynard (post 178, or #73355):If I understand you correctly then, and please correct me if I am wrong, you are saying that there are no designers in our society because there is actually no design either. All our technological and artistic civilization does not include any actual designs. It's the result of some kind of automatic process, basically a blind Darwinian process working both on the levels of genes and of memes.Are you sure you are not here changing the meaning of the concept "personal design", or if you prefer "intentional design"? Are you saying that it's not really they that did the designing, but rather they and all their ancestors including prokaryotic bacteria of 2.5 billion years ago?Well, no, because if you kept reading you would see the line "Were [our prokaryotic ancestors] mindlessly reproducing with that end in mind?" I was implying "no", which you'd know if you had read the next line. "That's not design, bub".
For me "supernatural" denotes anything one posits beyond the nature we ourselves can see, i.e. the physical universe around us (and just maybe other parallel universes that follow our universe's kind of mechanical laws). So anybody who is claiming a transcendental world beyond our physical universe which may be of a quite different kind than our universe is claiming a "supernatural" world by definition. Now it seems that you are saying that, according to your definition of "supernatural", if in that transcendental world beyond our universe anything similar to natural evolution exists then it is not really supernatural. Well, that definition is fine with me, for I can then argue that the God who designed and created our universe and all in it is not really supernatural but rather completely natural. You see in my understanding God is a dynamic, qualitatively growing, and indeed evolving being, as for me the whole of reality is a dynamic, qualitatively growing, and indeed evolving personal reality which transcends the physical/mechanical universe we observe around us. And please don't think that this is just my own personal understanding, see for example "process theology".So the God hypothesis, as defined by Dawkins, allows for that designing intelligence to have evolved by some means too. As a matter of fact it allows for that intelligence to be some kind of alien race living in some unknown world where they have the capability of designing and creating universes like ours.It says "supernatural". Did.. did you miss that? Because there's a word in the phrase "natural selection" which doesn't mix with a word meaning "above nature". I don't know what else to say to that..
OK, let me clarify my meaning. Consider the (Kolmogorov) complexity of two worlds, which we shall here call "E" (for experiential) and "M" (for material). E consists of about 7 billion subjects experiencing life exactly like we do, and 1 person imposing order in their experience (in particular imposing the physical facts and laws present in their experience of physical phenomena). M consists of an actual physical universe of the dimensions, complexity and laws that our physical universe has, and in which 7 billion people exist experiencing it (how that universe actually produces experience is irrelevant; we assume it does). I estimate that the complexity of E is many orders of magnitude less than M's. For details please see the latter part of post 1166 (or #55061) in the McGrath thread. Please note that I don't consider that result especially significant, but I think it does show that a theistic hypothesis is not necessarily more complex than a naturalistic hypothesis.The existence of the physical universe as understood by naturalism is not a given; what is given is our experience of the phenomenal universe. And a complex (i.e. "brain-like") mind able to produce/simulate that experience for all of us turns out to be several orders of magnitude less complex than the simplest naturalistic description of the universeI'm not clear on what you're saying here. Is it "What our mind can perceive is more complex than our mind"?
Given our experiential paradigm, the amount of complexity we can phenomenologically perceive with our evolved sensory apparatus is actually a lot less complex than what is there.Yes, exactly my point.
I'm also necessarily referring to the state of these atoms, where they're going, what speed they're moving at, things like that.Yes exactly, that's needed to compute the complexity of M.

Newatheist (post 182, or #73382):I am afraid this comes from reading TGD ;-) In fact only the most primitive theistic views (i.e. religious fundamentalism or Biblical literalism) have any trouble with scientific knowledge, including natural evolution. And there are many many theists who do not share these naive beliefs, and therefore have no trouble with science whatsoever (e.g. liberal Christians). There is even Newton, arguably the greatest scientist of all times, was a theist. As for modern times, in 1993 a Quaker won the Nobel prize in physics :-) That a theist's ontologically beliefs necessarily contradict science is just another naturalistic myth, one that unfortunately TGD fosters.I personally believe that there is a naturalistic explanation for the origin of life.Eh? Like, now I'm totally confused!

Brother john writes:He, by the way, if anyone, could show Richard that theology too is cumulative. His booklet, quoted above. is an example of just such cumulative theology, that starts on the shoulders of so many past writers (and ages) and moves forward.How, in theology, does one distinguish a movement forward from a movement sideways or a movement backwards? Personal preference? I think that that was Dawkins's point: that theology is not cumulative since there is no way of telling whether a change makes it "more correct" or "less correct".

Goldy (post 184, or #73392):I believe the question about the designer is because if everything is designed, then surely something must have designed the designer.It's an error to take a rule or property that is valid in one domain and simply apply it in another domain. For example: From the fact that atoms are countable it does not follow that numbers are countable. From the fact that it is reasonable to ask for the cause of some events (e.g. why is there some spilled milk on the floor) it does not follow that it is reasonable to ask for the cause of the universe, not to mention of reality itself. (In fact quantum mechanics teaches that it is not reasonable to ask for the cause of very small events either.) From the fact that physical space has several dimensions it does not follow that time should have several dimensions too. From the fact that A is explained by B it does not follow that B must be explained by some C. From the (dubious) fact that intelligent people have a more complex brain it does not follow that God, being hugely more intelligent, should be hugely more complex too as Dawkins apparently thinks. And, indeed, from the (claimed) fact that we people living in the natural world (and we are designers too) have been designed by a supernatural designer it does not follow that that supernatural designer must "surely" be designed too. That's all really very bad logic.

Goldy (post 188, or #73450):Well, say you are looking at an apple on the table. Sure, some particular electro/physical processes are taking place in your brain while you are doing this, but this does not imply that you are not really looking at an apple on the table, does it? A common naturalistic confusion is to think that because there is a correlation between brain processes and experience, experience somehow is less real. For example some naturalists point out that religious experiences can be induced by eating a particular kind of Mexican mushroom, implying that therefore when one is having religious experiences one is not really experiencing God. But that's like saying that the fact that the experience of light can be induced artificially (say by closing your eyes and applying sudden pressure to your eyeballs) implies that when we experience light we are not "really" experiencing it.Not to put a fine point on it: when you see something that strikes you as beautiful you are seeing a reflection of God's objective beauty. You don't have to agree with any of these of course, but that's what I mean.and I thought it was because of the electrical and hormonal etc impulses in the brain. I'm not 100% sure any god is present there

I asked myself, where did this thread go wrong? Think I found the problem: Janus said the creator must be complex. Dianelos introduced the more specific (and therefore more difficult to support) claim: "at least more complex than anything it creates." That's how we got stuck in that irrelevant debate about whether stupid engineers can create clever computers.
We need not specify God's relative complexity. "Pretty damn complex" will suffice. Janus' original point stands.
Janus:Couldn't have said it better.
