PZ's first comment in full is:
&quo...Maarten,<br /><br />PZ's first comment in full is:<br /><br />"The nature of this god is always vague and undefined and most annoyingly, plastic — suggest a test and it is always redefined safely away from the risk. Furthermore, any evidence of a deity will be natural, repeatable, measurable, and even observable…properties which god is exempted from by the believers' own definitions, so there can be no evidence for it. And any being who did suddenly manifest in some way — a 900 foot tall Jesus, for instance — would not fit any existing theology, so such a creature would not fit the claims of any religion, but the existence of any phenomenon that science cannot explain would not discomfit science at all, since we know there is much we don't understand already, and adding one more mystery to the multitude will not faze us in the slightest.<br /><br />So yes, I agree. There is no valid god hypothesis, so there can be no god evidence, so let's stop pretending the believers have a shot at persuading us."<br /><br />AFAICT it is consistent with what you have written. The only difference would be that you may have examples of theistic claims that are not "vague and undefined" or "plastic". ID'ists sometimes make this claim -- but do they really hold to it in the face of discomfirming evidence, or does it get plastic in the end?<br /><br />MikeAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-24761391.post-91314811670422498442010-10-30T02:45:19.367+11:002010-10-30T02:45:19.367+11:00That's right, the burden of proof is on those ...That's right, the burden of proof is on those who exclude the supernatural a priori to provide a clear and consistent definition, I hadn't thought of it that way!Maarten Boudryhttps://www.blogger.com/profile/11113078577333909378noreply@blogger.comtag:blogger.com,1999:blog-24761391.post-23798083859704772452010-10-28T18:49:14.699+11:002010-10-28T18:49:14.699+11:00Like most words in natural language, the meaning o...Like most words in natural language, the meaning of "supernatural" is given by a cluster of associations that the word has for us. We have a pretty good idea of which entities get labelled "supernatural" in common parlance, even if it's difficult to say just what these entities have in common and there are questionable cases. There's no need for us to come up with a definition unless we are using the word in a way that makes such a definition necessary. IMN supporters do use the word in such a way. Since they are claiming that a certain type of hypothesis is necessarily excluded from scientific consideration, they need to say what type of hypothesis that is. So the onus is on them to say what _they_ mean by "supernatural". They usually fail to do so until challenged, and then come up with a wide variety of different definitions.<br /><br />I don't think PMN requires a definition, because it's only a vague guideline or attitude, not a definite rule. So the vague everyday usage of "supernatural" is sufficient. Scientists tend to ignore the sorts of hypotheses that might get labelled "supernatural" in everyday parlance. It doesn't matter if there's uncertainty about whether to label some hypothesis "supernatural", because scientists are not really interested in the label. If there's a questionable case, they should consider that case on its own merits, without regard to labels.<br /><br />There are plenty of other hypotheses that scientists routinely exclude, besides "supernatural" ones. Scientists don't keep asking themselves, "should I consider the hypothesis that an unknown extraterrestrial got into my laboratory and interfered with my experiment?". I would say that PMN is just a particular case of the more general principle that "extraordinary claims require extraordinary evidence".<br /><br />So in my view there was no need for Maarten et al to give their own definition of "supernatural".Richard Weinhttps://www.blogger.com/profile/18095903892283146064noreply@blogger.comtag:blogger.com,1999:blog-24761391.post-86556868812856629162010-10-28T12:45:25.705+11:002010-10-28T12:45:25.705+11:00I do not doubt that an unclear or even incoherent ...I do not doubt that an unclear or even incoherent definition of "supernatural" is a big problem. And really, I also believe that the best definition of supernatural would be an empty set: nature is everything that exists, even if it includes gods or souls.<br /><br />But the problem is, Massimo Pigliucci and Eugenie Scott apparently define supernatural as capricious - in one of the discussions over at his blog, MP went as far as saying "if it follows clear rules, why would you call it supernatural?"<br /><br />But what I have tried to point out over and over again is that many people do not use that definition. They will quite happily call magic or faith healing supernatural even if they expect it to work reproducibly and reliably (that seems to be the entire point of magic, no?). If you then go on and say, as the NCSE and MP do, that science cannot examine the supernatural, these believers will not understand this to mean that science cannot test claims that are nothing but goal post moving, which is trivially true anyway, but simply that science is forbidden from saying that faith healing does not work!Alex SLhttps://www.blogger.com/profile/00801894164903608204noreply@blogger.comtag:blogger.com,1999:blog-24761391.post-34166407736657249042010-10-27T21:35:05.063+11:002010-10-27T21:35:05.063+11:00I would suggest that as naturalists, it is far bet...I would suggest that as naturalists, it is far better to start by defining what "naturalism" means and work our what "supernatural" means by contrast. It is more productive to formulate a positive doctrine that we could then contemplate and justify or amend than to adopt the definitions and discourse of another worldview. <br /><br />For myself, I believe the fundamental doctrine of naturalism is the <i>Principle of the Uniformity of Nature</i> that Hume so long ago identified as the unjustified assumption underlying empiricism. Naturalistic universes are ones that are highly uniform, especially in some specific ways (such as causality). This makes them easily amenable to scientific inquiry. Current physics indicates that our universe is uniform to almost absurd levels (e.g. all types of fundamental particles exist everywhere, just in varying degrees). <br /><br />This leads by contrast to the idea that "supernatural" worlds are ones that are non-uniform. This does not necessarily imply that scientific investigation is precluded. If the non-uniformity is itself regular (e.g. prayer works, in defiance of the laws of physics), then the supernatural can be investigated scientifically. If the non-uniformity is taken to the extreme, a world with no uniformity at all would not allow science to work - but then again, it would not allow sentient creatures to exist, either, as that too is a uniformity. So from the weak anthropic principle, it arises that the type of non-uniformities that we could expect in our world if it is supernatural are probably amenable to scientific investigation. "Capricious" phenomena may, however, make such investigations impractically difficult.<br /><br />This is of course but one way to define the "supernatural". But it appears to me that this is a good way for a naturalist to do so.Yairnoreply@blogger.comtag:blogger.com,1999:blog-24761391.post-73350607880046625622010-10-27T20:54:31.315+11:002010-10-27T20:54:31.315+11:00Even worse, if you read PZ's posts with a beli...<i> Even worse, if you read PZ's posts with a believers eye, you will find it very hard not to understand them as an open admission that atheism is just another blind faith.

Ironically, there seem to be two very different kinds of people who hold that there could never be scientific evidence for the 'supernatural'<br />- atheists like PZ Myers ans Steve Zara, who want to make clear that believers don't even stand a chance of convincing them, because they will never budge<br />- accomodationist and theologians like Eugenie Scott, John Haught & Robert Pennock, who want to make sure that science has no (negative) bearing on the supernatural, so that religion is safeguarded.<br />(I'm not sure where Massimo Pigliucci fits in here!)<br />Both positions are counterproductive, because they come off as dogmatic and closed-minded. I would say especially for the accomodationists: if they explicitly leave open the possibility of supernatural intervention, why do they exclude it a priori as a matter of methodology? Now all the ID pundits are whining that God is already “disqualified at the outset”.

Which at least to me, does not seem to be the idea, I guess? He is also an atheist, but he likes to bash atheist scientists for daring to reject god based on lack of evidence, and thinks that only philosophers are qualified to comment on the issue.<br /><br />Even worse, if you read PZ's posts with a believers eye, you will find it very hard not to understand them as an open admission that atheism is just another blind faith.

"...<a href="http://www.askwhy.co.uk/truth/420GouldNOMA.php" rel="nofollow">Wednesday, 10 July 2002 at www.askwhy.co.uk</a>:<br />"Eugenie Scott... made a distinction between methodological and philosophical naturalism to leave a scientific gap for God. She says science adopts naturalism simply as a methodological tool for doing research, but this methodological tool does not dismiss God. The naturalist who denies the existence of God is a naturalist in a philosophical sense -- the physical world is all there is. She is saying that Christians who wants to practice science can pretend that Nature is all there is in the lab, and then they can resume their belief that God is all important instead when they leave it. For Scott, naturalism is not a scientific conclusion, but an assumption of the scientific method, and so science cannot inform us as to the existence of God. Since Scott admits that religion has nothing to say about anything natural, then NOMA must be true.<br /><br />"What is ignored is that the scientific method could not work unless naturalism was true in practice. If the finger of God waggled incessantly in everyday affairs according to His whims and the prayers of individual Christians, then science would notice it because effects that are uncaused would be commonplace. Gould admits that a personal God would contradict the scientific evidence. If the God behind the universe works in subtle ways, and entirely through natural laws, as some theistic scientists say, it is impossible to infer His presence. It is therefore more parsimonious to assume His absence. The best that can be had from Scott’s argument seems to be that God is absent in practice! If God is what most people think of as God, NOMA is invalid."AskWhy!

I think it's fair to say that these days it's used to describe supposed phenomena that <i>mustn't</i> be explained by science: once a miracle is explained, it's no longer a miracle.<br /><br />I think we can have all kinds of arguments about meanings, but they aren't of any use unless we look at motives, and the motivation for what seems to me to be a pointless division of the world into natural and supernatural seems clear: to define ideas that aren't vulnerable to destruction by science and reason. The point of the supernatural is that there should be a "behind the scenes" of the universe, which humans have access to, so we can avoid the consequences of a vast and unfeeling universe.Steve Zarahttps://www.blogger.com/profile/16867968082532563442noreply@blogger.comtag:blogger.com,1999:blog-24761391.post-18592442825230299612010-10-25T19:47:11.840+11:002010-10-25T19:47:11.840+11:00At the risk of beating my own drum, I'm anothe...At the risk of beating my own drum, I'm another one who's been saying this for years, though not as eloquently as Russell or the three Bs. The recognition that there are two meanings of "methodological naturalism" in use is important. I've referred to these in the past as <i>a priori</i> MN and rule-of-thumb MN (IMN and PMN respectively).<br /><br />It seems to me that supporters of IMN like it for two reasons. They see it as useful for keeping religion out of science (as an argument against ID) and for keeping science out of religion (its role in "accommodationism").<br /><br />As an argument against ID it can be counterproductive (as well as fallacious).<br />1. It distracts from all the good arguments against ID, the scientific arguments. ID advocates can focus on the argument from IMN and give the impression that ID critics have nothing else.<br />2. It undermines the argument from authority against ID. ID advocates can claim that scientists have have an <i>a priori</i> rule that prevents them from accepting ID regardless of the scientific evidence, so their knowledge of science is irrelevant.<br />3. There may be people who haven't considered the science in detail but can see that the argument from IMN is fallacious. They are liable to think, "I've seen the ID critics make one fallacious argument, so I'm going to be a lot more skeptical about everything else they say".Richard Weinhttps://www.blogger.com/profile/18095903892283146064noreply@blogger.comtag:blogger.com,1999:blog-24761391.post-86769894688580027622010-10-25T17:46:05.774+11:002010-10-25T17:46:05.774+11:00Steve, our comments must have been made at the sam...Steve, our comments must have been made at the same time. You write, "nature looks increasingly, etc." So my question is (and I would ask PZ Myers the same): Do you want to say that <i>what we know now</i>, from our scientific discoveries, makes any assumption of the supernatural existing nonsensical, or that any definition of supernatural whatsoever was incoherent <i>from the get-go</i>, even 6000 years ago, and science could thus never have found evidence for it to start with?<br /><br />If it is the first, then there does not seem any basis for disagreement, but it also does not seem to be the point. I do not think that Jerry Coyne, Russell Blackford or any other reasonable person expects science still to be able to find evidence for the supernatural now, with all that we already know making it extremely unlikely. The claim is that it could have turned out differently, that we could not have known 6000 years ago that we find ourselves in a universe where disembodied intelligence is very likely impossible, that was very likely not created fully formed just a few years earlier, or where we were very likely not bestowed with immortal, immaterial souls that survive the death of our bodies and can be spoken to through a shamanic trance.<br /><br />Don't get me wrong: I would also call all these phenomena part of nature, if they existed. But that is not very helpful. The question then simply becomes: if we call ghosts, souls and faith healing fuzzlegarb instead of supernatural, could science have found evidence for the fuzzlegarb?Alex SLhttps://www.blogger.com/profile/00801894164903608204noreply@blogger.comtag:blogger.com,1999:blog-24761391.post-69272005609216337662010-10-25T16:14:04.591+11:002010-10-25T16:14:04.591+11:00Of course, science cannot investigate the supernat...<i>Of course, science cannot investigate the supernatural if we define "the supernatural" as "whatever cannot be investigated by science"!</i><br /><br />That seems to be the trick. Massimo Pigliucci and Eugenie Scott simply define "supernatural" as a synonym of "capricious". And when you point out that claims of capriciousness could be made for all other phenomena (cryptozoology, quack medicine, etc.), the answer is that you are not allowed to do that in these cases. But for god, you are. And so help me, but that special privilege seems to be granted to the faithful <i>for the sole purpose of being able to say that science cannot examine the supernatural</i>. Kinda frustrating.<br /><br />Others make the much more interesting point that there is no coherent definition of supernatural. To your example of disembodied intelligence, they would in essence reply that we know that this is impossible. But how do we know that it is (very likely) impossible? Only because of scientific evidence that we have accumulated!

But then I also have a problem with naturalism. They both seem to be outdated descriptions of a reality whose true "nature" looks increasingly beyond anything we can easily understand. I wrote an article at RD.net recently that was referred to by PZ and Coyne on this subject, and seemed to kick off this Gnu Atheist discussion, expressing position of refusal to accept the possibility of evidence for God/supernaturalism. I'm probably a bit too fundamentalist for you about this, but I think a new approach is needed rather than conceding that terms like "supernatural" are meaningful. I really don't think that they are. They express a desire for what reality should be like rather than a coherent position on what reality could be like.Steve Zarahttps://www.blogger.com/profile/16867968082532563442noreply@blogger.com
