Kuhn and Intelligent Design

As an admirer of Thomas Kuhn's work on the philosophy of science, I've had some discomfort with the positivist table-pounding that's tended to be associated with the pro-science counterattack against intelligent design. Since Noam Scheiber's new column attacks intelligent design by associating it with Kuhnian "postmodern" attacks on science, it seems that the time has come to spell out why I think one can -- and should -- be both a good Kuhnian and a good Darwinist.

Having thought about it some, I think the argument is actually rather straightforward. In Kuhnian terms, what Darwin did was "revolutionary science" -- he laid out a new paradigm for thinking about biology, the relationship of species to one another, and their origins. Kuhn points out that it's entirely typical of enterprises in revolutionary science that they don't really explain all the data. Instead, you have "anomalies" -- bits of data that don't obviously fit into the framework. Any honest appraisal of The Origin of Species needs to concede that there were, in fact, a lot of anomalies left by Darwin's initial formulation of his theory. Most notably, there were massive gaps in the fossil record and a lot of hand-waving associated with the account of how inheritance worked. On top of that, while Darwin did rebut the "watchmaker" argument with specific regard to the development of the human eye, there were many other apparent cases of "irreducible complexity" that Darwin didn't take on.

To the IDers, all this is supposed to show that Darwin was doing dubious work that we should be suspicious of. A Kuhnian, however, understands that this is entirely typical of revolutionary science. Copernicus, Einstein, Newton, and all the great names of science did work that was similarly problematic. Or, rather, not problematic at all. These are the great scientists of human history -- that's what great scientists do.

The reason we regard them as great isn't that their own work was free of anomalies, but that the paradigms they proposed were fruitful for doing what Kuhn called "normal science" -- applying to new paradigm to solve problems.

In the Darwinian case, post-Darwinian biologists (and others) kept doing research on these problems and progressively started solving them. We've found more and more fossils and consistently been able to fit them into a Darwinian framework to enhance our understanding of the history of life. Mendel's work was rediscovered, found to integrate very well with Darwinism, and launch a fruitful line of research into genetics. We were then able to further improve on Mendel's account with the development of molecular genetics, the discover of DNA, and all the bits of work that have come out of that. Beyond the human eye, scientists have had occassion to look at many, many other putatively "irreducibly complex" traits and propose Darwin-consistent accounts of their origins.

The upshot of this is that a Darwinian need not deny that, as IDers claim, the Darwinian account remains to some extent incomplete. What we claim for ourselves is that while it was initially promising it was, at the time, very incomplete and has steadily grown less and less incomplete. Therefore, the mere fact that some anomalies remain is hardly a decisive refutation. Many scientists are still working on these problems, expanding our command over the natural world, and we have good reason to anticipate that they'll continue to succeed.

Similarly, the brute fact that ID has a lot of problems doesn't refute it. The problem with ID is that, unlike real revolutionary science, it doesn't lead to any normal science. There are no ID-based research programs. Nothing has never been accomplished by applying the ID paradigm to a question in biology. All ID's scholarly (and "scholarly") proponents do is try to offer half-assed refutations of Darwin. You can quote Kuhn all you like, but you're not doing revolutionary science unless your purported revolution leads to some normal science. Intelligent design does not.

At the end of the day, I think this Kuhnian approach to the question is not only a more accurate account of ID's problems than a more naively positivistic one, but it puts the evolutionist on stronger ground. Let me quote the end of Noam's article:

When a proposition is empirically false, as both creationism and ID (to the extent that it makes empirical claims) are, you're free to assert its truth; you just can't call it science. The creationists had no problem with this; they just rejected any science that contradicted the Bible. But the IDers aspire to scientific truth. Unfortunately, the only way to claim that something empirically false is scientifically true is to question science's capacity for sorting out truth from falsehood, the same way postmodernists do.

I think that gets at the crux of the issue in a lot of ways. In some sense, it's not possible to demonstrate that creationism is mistaken. God -- being omnipotent -- could surely make the evidence come out whichever way He might see fit. The thing you can say about both creationism and intelligent design is that they're not science. That, however, depends on recognizing that science is fundamentally a social practice. Creationists refused to conform to the norms of that practice. IDers have managed to superficially ape the norms of the social practice but are not, in fact, participating in it.

This is something that you really can conclusively demonstrate. By contrast, if people simply choose not to accept the conclusions of science, there's really nothing you can do to stop them or to refute them. But you can say, both logically and politically, that what ought to be taught in science classes is science, that there are standards as to what constitutes science, and that intelligent design isn't it.

I agree with everything you say, except that the part about science being a "social practice" could use a touch-up.
It's true that the way particular scientists live and work and investigate constitutes a social practice.  And I like your formulation that the Creationists rejected it, while the ID'ers ape it.
What I don't like is the implication that science might be a *mere* social practice.  That would make it far too contingent and conventional.  Driving on the right hand side of the road is a "social practice" in our country; driving on the left is the "social practice" in the UK.
IF science were a "social practice" in that sense, Creationists would be within their rights to say "fine; we don't like that social practice and we prefer another".
But here's the thing:  what lies at the heart of science is not merely a social practice.  What underlies, shapes, and justifies that social practice is *the way reality is structured*.  The "social practice" of science has the structure it has, because it has consistently delivered the goods in revealing more and more about how the world really is.  The shape of the globe, the pressure of the atmosphere, the behavior of the atom--all of these were both discovered by science, and also influenced the way that science is done.
There is no other "social practice" that is anywhere near as successful at delivering knowledge, prediction, and control of the world.  Not studying the I Ching.  Not perusing liver entrails.  Not memorizing Genesis.  Those might be on equal footings with science to the extent that they too are "social practices".  But that just shows that science is more than a "social practice"; it's the social practice that best tracks the structure of the world.

Very good, Matt! That is one of the best arguments I have read about ID and creationism. All I would add is that a new theory, such as Relativity, does not make the previous theory, such as Newton's, wrong. It merely extends the understanding of the physical world. Newton's laws are still as good as they ever were and still provide excellent results when used to analyse things in the ordinary world. And, Einstein's theories still work as well as ever for things moving very, very fast, or with very high energies. Quantum theory doesn't refute either Einstein or Newton, but enables better understanding of very small things. And, I suspect string theory, if it gets accepted, will not refute the earlier theories, but extend the understanding of still more extreme events. ID, on the other hand, does nothing at all to help us to understand the physical world.

It really doesn't seem right to associate the IDers with Kuhn.  How could all of the other beliefs IDers hold, all of the religious beliefs that they're trying to sneak into the system, possibly withstand a Kuhnian or postmodern assault?

Science is not a "social practice". Science is a methodology. And the key point is, science is the best engine for generating real, unequivocal answers that humans have yet found.

In fact, if it can't be expressed in scientific terms, if theories can't be formulated and experiments can't be designed to test it, it isn't worth even discussing, unless you are satisfied with the sky-castles of philosophy.

That's the way science works. It starts with a theory, possibly incomplete. It continues through designing ways to test and expand on this theory, until after possibly many years, you have a fully fleshed-out theory - which might STILL be overturned tomorrow by new evidence. The antiscience crowd crows over the great mistakes in the history of science; what that don't "get" is, that's how science works. We know of these mistakes because some later scientist pointed them out and postulated a better explanation for whatever phenomoenon we might be talking about.

In science, we rely on Occam's Razor. There is no need to postulate invisible pink unicorns when a perfectly understandable explanation exists.

I agree with most of the rest of what you have to say.

Sheesh. Talk about missing the point.

Yes, Origin of Species codified revolutionary science at the time.  Yes, evolutionary theory is now normal science. Everybody believes it, the way everybody believed in Newton's law of gravity in 1898.  And he way everybody believed in the ether, as well.  Oh, and determinism. Can't leave that out.

Kuhn makes a couple of claims. One of them is that revolutionary science takes a while to settle in, because there are institutional and social pressures slowing down change.  Science is, by its nature conservative.  Scientists, for example, never bought the cold fusion thing, but they did normal science on the idea nonetheless, eliminating it as a source of revolution.

It's hard to think of something revolutionary that will overthrow natural selection, just as it is hard to think of something that will overthrow the round earth theory. There's a point where evidence accumulates to the point that we're not talking theory anymore, we're talking fact.  We don't happen to be at that point in a number of scientific areas, but we certainly are there wrt evolution.  In an associated realm, the origin of the first replicator is an interesting open question. 

But that's not what Noam (I don't, pardon me, know 'im, but we all seem to on first name, or abbreviated handle basis here) is talking about.  He's talking about some side observations that come from the acceptance or rejection of revolutions.  (Feyerabend makes these observations in a funnier, more pointed way in Against Method)  That is, societal norms play a role in how slowly or quickly an innovation is accepted.  Despite Einstein's contributions to the idea that the universe is probalistic and not deterministic, he never really believed it it--an underlying you-can't-really-call-it religious thing he had going rejected probabilistic models as incomplete.

Now THIS is the kind of thing post-modern folk like to talk about. Science isn't really about real reality. It's all relative to what we believe to be true in our culture and our social milieu.  What gets accepted, even among scientists, depends on what is socially acceptable.

What Noam is saying the IDers are trying to do is introduce social acceptability explicitly into the framework for evaluating the validity of scientific results.  That is, instead of our accepting or rejecting scientific (or historical or literary) ideas because of a hidden socio-cultural framework that only post-modernists can perceive, they we should just say out loud what we all know to be true--that there has to be a designer.

That is, we just freakin' know that if we find a watch, somebody made it. If we see blood stop flowing in a wound, of its own accord, and we find there are seven different clotting agents involved we just know that this didn't come about because God was throwing dice.  It had to be the result of conscious design. 

Scientists, the IDers say, deny this underlying knowledge exists. They  want to make it part of our understanding of the world--that how the world works is actually in relation to experiences and our social framework. We have to accept that there are true ideas other than those worked out in a a lab.

Now this is all a buncha hooey.  Kuhn doesn't say we embrace false theories because of social pressures.  Kuhn says that it isn't enough to be a better theory. You also have to win the institutional and political battles to get on top.  But he doesn't say that scientific truth is relative.

Complicating this is that "scientific truth" is tricky. Some questions are simply no longer open, like heliocentrism. Some questions are so open that the scientists sound like members of religious sects, like the origin of the universe and the various flavors of the anthropic principle.  Some are still having the details worked out, like whether there is a graviton or not, and if there isn't why is there this particle zoo, and if there is, why is it so hard to find?

So, to cut to the chase, Noam's point is simply that it is very ironic that the very people who reject post-modernism where it actually makes some sense, like whether morality is relative to culture instead of absolute, or that literary quality, or even the meaning of words, can be culturally dependent, or even individual reader dependent are the ones who want to introduce it where it doesn't make much sense.

To some degree, Kuhn is a red herring here. The post-modernists use him to say "even science is post-modern."  Well, to the degree anything is, science is the least of the post-modern disciplines. And it's pretty funny that the wingnuts choose that discipline to haul out the post-modern carbines.

That's typically what unsettles people about Kuhn.  It doesn't change Kuhn's point, though.

IF science were a "social practice" in that sense, Creationists would be within their rights to say "fine; we don't like that social practice and we prefer another".

Why aren't they "within their rights" to do this as regards the social practice of Western science?  I don't agree that it would be a good idea for them to do this, because I agree with you that Western science is the best social practice for finding things out about the world around us.  But I'm hard pressed to understand why they would have no moral right to reject Western science if that's what they think is best.

<i>All I would add is that a new theory, such as Relativity, does not make the previous theory, such as Newton's, wrong. It merely extends the understanding of the physical world.</i>

This is precisely wrong.  Einstein's theory of gravitation (geneal relatively) expressly says that Newton is entirely and completely wrong. There is no action at a distance. Bodies do not attract one another.  Space and time are not distinct, and there are no preferred spatial locations or preferred velocities.

It's true that when NASA calculates a launch, it uses Newtonian calculations. And they work fine. But the theory underlying those calculations is simply wrong.

In a comment I made a few minutes ago, I said that there questions that are still open. This is one of them. Einstein's theory of gravity does not work and play well with the other forces (strong, weak and electromagnetic).  Its lovely tale of geodesics and dimples in spacetime may be supplanted. But we will never return to believing that the Sun reaches out with invisible fingers and pulls the earth toward it.

I have a question for Matt and Tad Brennan.  I was exposed to a lot of bad readings of Kuhn as an undergraduate, and have never actually read him myself.  So I am looking for clarification on something.

The view that I remember being attributed to Kuhn was that, because of the whole anomaly thing, the movement from one scientific paradigm to another is underdetermined by the scientific data, and thus is best accounted for in terms of facts of a sociological nature.  That seems vaguely in the same ballpark as Matt's idea that we think of the scientific enterprise as primarily a social practice, but is obviously really different than what Tad is saying.

Did Kuhn say anything like that?  I am asking out of genuine curiosity.  The early 1990s was a terrible time to be receiving an undergraduate education in this country.  I am only just beginning to undo the damage.

A few things to point out-


First of all, Darwin's theory was developed from a pretty complete body of data of European animal and plant husbandry and coming up with an adequate explanation for a lot of familiar, pan-European barnyard breeding and plant cultivar phenomena.  Confirming the scope to extend to nondomesticated and exotic species via sufficient data was the point of the HMS Beagle expedition.  In essence, the core of evolutionary theory started out as a narrow hypothesis whose truth was never really in doubt, is beyond refutation, and whose extension to most living species was pretty straightforward.  The extension of it to all species, all space and all time and all organisms that have ever lived, is the trouble, not the foundation(s).


Secondly, ID is transparently an ideological halfway house.  It's an admission that physical science and the scientific method can no longer be rejected by the Creationists.  They pretend it's an ideological halfway house for their opponents..the truth is, of course, that it's one for their own adherents/children.


The point of ID is itself curiously and ironically evolutionary- clearly it's going to have to move, argumentwise and as rhetorical emphasis, to ever more semantic and elusive/dubious claims as biological research dismantles all the 'irreducible' complexity.


In sum, ID is necessarily going to undergo the theological shift that is the hallmark of Modernity.  The God of Nature theory, aka strict theism, is going to hollow out and there will be a migration of the agenticity of God into the human Imagination, i.e. nontheism.


The way to deal with IDers and Creationists is to publicly Not Believe them.  In the end this an argument about consensus of imagination and rigor of argument; Science has little or nothing to say about imagination (nor should it) and there's simply no bargaining about rigor with people who don't know what it really is.  That is why Dawkins and Gould refused to "debate" the Creationism activists- and rightly so.

In the first place, Kuhn is primarily speaking about the scientific community, not the community at large. I don't doubt you were told that Kuhn argues that science reflects broader social movements, but this is a more typical passage:

Because it demands large-scale paradigm destruction andmafor shifts in the problems and techniques of normal science, the emergence of new theories is generally preceded by a period of pronounced professional insecurity.  As one might expect, this insecurity is fenerated by the persistent failure of the puzzles of normal science to come out as they should.  Failure of existing rules is the prelude to a search for new ones. 

(pp66-67 of the UChicago paperback, 2nd edition)

 

For example, special relativity caused a big ruckus, but the ruckus was in the air already, because of the Michaelson-Morley experiments. The Lorenz transformations had already been worked out.

Thank you JayAkcroyd. I'd add that the relevant issue if one wants to invoke Kuhn to discuss Darwin is not Darwin and Huxley vs. Wilberforce but why actual readers of scientific publications in the mid to late 19th century turned to Darwin over Lamarck (whose theory of evolution had a much greater following than predecessors of Darwin earlier in the 19th century).

Sundog,
In fact, if it can't be expressed in scientific terms, if theories can't be formulated and experiments can't be designed to test it, it isn't worth even discussing, unless you are satisfied with the sky-castles of philosophy.

That's a pretty good definition of positivism. Of course, your statement is itself not testable and therefore not worth discussing, according to your own understanding. That's the performative contradiction of positivism- as well as various forms of relativism and extreme scepticism. don't dismiss the value of philosophy so quickly.

Intelligent design is lousy science.

If you say that the complexity of life implies an intelligent designer, I reply that your desinger seems to be very complex and must have a designer. And that designer must have one, so must the next designer. and so on and so forth.

Next thing you know, you can't get a parking spot at the mall cause of all the intelligent designers who are their shopping.

I have no particular dispute with Matt's analysis, but I think it's fair to say that practicing scientists don't view it this way, which is why their criticism of ID pseudoscience may sound positivist and may not be to Matt's taste. But think we ought to defer to the scientists in this regard, because they, and not Kuhnian philosophers, are the stakeholders. I.e., scientists are the ones who want high school to teach kids science as it is practiced.

As I said on Brad DeLong's blog, when you teach high school French, you do not address the "controversy" over whether to pronounce certain final consonants, because there is none in the mind of a French speaker. Likewise, there is no controversy over the correctness of at least some version of evolutionary theory within the mind of a practicing biologist. Now I personally think that evolution is objectively true while French is a cultural construct, but at the very least I think that every pedagogical precedent requires the teaching of biology in terms of how biologists work, so I don't see how you can even begin to make an argument for putting ID in our schools.

 Any honest appraisal of The Origin of Species needs to concede that there were, in fact, a lot of anomalies left by Darwin's initial formulation of his theory

The problem is that biologists don't spend their time appraising Darwin's writing. I think it's fair to say that most scientists find it jarring to hear "Darwinian" as a noun applied to a kind of person (it might be acceptable as an adjective in some contexts, such as a description of a model).

While Darwin's work was seminal and Kuhn would call it a paradigm shift, the basic idea is second-nature to practicing biologists, who feel free to extend the principles of natural selection to their observations without any reference to Darwin, or even Mendel. I can tell you from personal experience that computer scientists usually learn about universal machines without studying Turing or Church, though their work was seminal. Physicists rarely read Newton or even someone as recent as Bohr. This is because the principles get distilled over time and the distilled principles are generally easier to grasp removed from the baggage introduced to make them palatable when they were new.

Actually, I think this falls into Kuhn's view (I only read the comic book version so apologies): Practicing scientists aren't interested in the paradigm as such, but spend their time solving problems within the paradigm. This is what biologists have been doing. The work has been quite fruitful in producing a series of falsifiable hypotheses and empirical demonstrations or refutations. I know that view of science may sound quaint to a savvy historian of science, but quaint or not, it is actually formalized in the kind of experimental protocol one must follow to get papers published. At the very least, scientists accept the scientific method as a convenient fiction for explaining their job.

Now creation scientists, young earthers and IDers alike, have been milking their own paradigm for just as long. As far as I can tell, all they have to show for it are endless variations on why they can't imagine evolution happening. Scientists have trouble imagining some of it happening as well, which is why they work out the consequences in the form of predictions and make observations to confirm those predictions. As each unimaginable part is shown to happen (adaptation of some characteristics like color, direct evidence of speciation occurring, in silico evolution of "irreducibly complex" subsystems) the creationists simply retreat into the next area not fully understood and insist that this part at least is unimaginable. (*)

The positivist defense in its simplest form is that you can't teach ID in science class because it's not science: it does not follow the scientific method. Or, if you prefer, it's not what scientists claim to do, and it's not what the vast majority of scientists actually do. Likewise, it may be possible to find a Frenchman who thinks there is an impressionist painter whose name is pronounced "mo-NETT" but this would not be sufficient cause to revamp our high school language departments. 

(*) There are plenty of anecdotes from science about why "it's just unimaginable" is a poor refutation. For instance, there is a phenomenon called the Poisson spot--roughly you will see a faint bright spot in the center of the shadow of a sphere. Poisson came up with this as an attempt to refute Fresnel's analysis of light as a wave, claiming the wave theory was wrong because this consequence was impossible. Science does not evaluate theories based on whether they conform to human prejudice but by whether they are consistent with observation.

This a bit off topic, but I'll say it anyway: the intelligent design "debate" is a red herring.  It's another example of the corporate GOP using the earnest convictions of the religious right as a trojan horse for corporate policies. 

GOP-backers like Exxon-Mobil and RJ Reynolds want to undermine the scientific method because it stands in the way of their profits.  Nothing complicated there: science cannot be bought off...and if the scientific method is followed, global warming will be real and cigarettes will cause cancer in 100 out of 100 studies.  Thus, the GOP must attack science itself.

The intelligent design debate is a GOP classic.  Like judges, scientists are generally respected and liked by Americans.  But evolution is the chink in science's armor - fewer than 50% of Americans believe only evolution should be taught in classrooms.  Through that small hole, the GOP can drive a truck.  They can't challenge science head on - but they can rely on evolution to politicize it.  As liberals and democrats rally to evolution's defense, they inadvertantly politicize science itself.  Once that happens, the GOP knows the gloves can come off.

The goal is to politicize scientists the same way they have politicized judges and jouralists.  All they need to do is muddy the waters of public opinion; create a little of the public cyncism we see with judges and journalists and tag it to scientists.  Once people are unsure how they feel about studies they see on the news, the GOP money advantage comes into play.  The same goes for the GOP's political superiority...once scientists become legitimate political targets, they can be personally attacked and discredited.

It's not complicated.  Look at what Republicans did to jouralists.  For years, the "liberal media" smear wasn't taken seriously.  Then one morning journalists woke up and realized that most Americans think they're biased.  Judges are next on the agenda.  Then scientists.

pjs -- The early 90s was an appaling time to be reading about Kuhn!  (But then again, so was the 70s and 80s, though they were appalling in different ways. . . . )

 You've got the basic idea of underdetermination right.  Kuhn didn't come up with the term, but his view is certainly associated with the idea. 

In it's Kuhnian variant, the idea that scientific theories are underdetermined by the data for them comes from the observation that, throughout the history of science, big theoretical shifts always seem to happen before anyone could plausibly claim that evidence for the new theory is decisive.  An old example of Kuhn's is the Copernican Revolution.  The old geocentric model of the universe fit the existing astronomical data better than Copernicus' heliocentric model.  And in fact, contrary to popular mythologizing, the data fit the old geocentric model well into Galileo's time.  By the time scientists had tinkered sufficinetly with the new theory, and had the instruments to take better observations, most scientists already believed the new theory anyway.  (Of course, the church didn't, but that's a different story.)

 So how would a historian of science go about explaining the shift from an old theory to a new one, if not by appeal to evidence convicing scientists?  Some non-empirical considerations had to have convinced scientists like Copernicus.  Like, say, considerations of theoretical simplicity.  But when you're talking about theoretocal simplicity, you're in a much more vague, subjective area than when you're talking about the data on astronomical charts,  In very real ways, scientists can disagree over what counts as simpler.  Values come in to play, etc.   And you're off to the sociological races.

Matt's right that this should absolutely not make people think a Kuhnian picture of science liscenses anything-goes relativism.  But it does point towards a view that sees an important role for social institutions (journals, conferences, research institutes, peer review, etc) in explaining why science is so good at producing  real and lasting knowledge.

This point about animal and plant husbandry  is worth emphasizing, for a couple of reasons. First, most people aren't really aware that one reason we use the phrase "natural selection" is in opposition to selection of traits by people through breeding. Darwin spent a lot of time studying controlled selection, which left him primed to observe it occurring naturally.

Second, in the context of the discussion, while the idea was revolutionary, it certainly didn't spring fully grown from Darwin's brow.  As Kuhn says usually happens, these ideas were around at the time.  The revolution was more a precipitating out of ideas  in the air than it was an AHA moment by Darwin.  It's this idea that post-modernists have conflated into scientific revolution coming in the context of social or cultural change.  Yes, the ideas are around at the time of the revolution. But they are around inside the shuttered world of the scientist.

The idea of ID as a halfway house for the creationists, rather than a fundamentalist camel's nose under the door to the science lab of your local junior high school is an interesting one.  It's consistent with some of the discomfort we're seeing from some of the IDers as the program has become as prominent as it has. 

It may be that the Wedge was not the primary goal of a lot of these folks--that they were just trying to ease in to the god-fearing the idea that maybe, just maybe, all of geology, astronomy, biology and most of physics isn't wrong.

Having read Kuhn back in the dark ages, the 1970s, doesn't he argue that facts, something the Royal Society of the 17th Century was so anxious to report, do not speak for themselves.  For facts to make sense there needs to be an explanatory theory that gives life to those facts.  The paradigm behind the theory is socially constructed.  Since all of the heros of the scientific revolution, Newton, Boyle and Descartes were seeking God's work in nature there is nothing incompatible between science and religion if religion is not taken to be a literal reading of one view of religion.


The trouble with ID as science is how do you disprove it?  What fact or set of facts would falsify it?  Given that ID is really a neatly altered version of Creationism demonstrate the problem with ID.  They need ID to be true no matter what the facts or rather the failure of ID to explain the known facts.  I presume that even if scientists sometime also sound like then need Evolution to be true they could tell you what it is that would demonstrate to them that it is a false theory and a new one is needed.

avatar IF science were a "social practice" in that sense, Creationists would be within their rights to say "fine; we don't like that social practice and we prefer another".   They already have that right.  What they don't have is the right to advertise their social practice falsely as "science" and foist it on unsuspecting students.   While I agree with you that science is more than set of conventions, and is in fact the best hope we have for grasping reality, I contend that even the weak assumption that it is a set of conventions is sufficient to keep ID out of high school biology textbooks, just as my "controversial theory" about the painters "mah-NETT" and "mo-NETT" should be enough to disqualify me from teaching high school French (another social construct).   Actually, the battle over whether evolution is "true" is less of a serious problem in practice; the main stakeholders are biologists and they have it right. If a lot of non-biologists don't... well, they also don't know how their TVs work, or think that shuttle astronauts are "outside the pull of gravity", or fail to grasp intuitively that a million is very very different quantity from a billion. I mean, I wish that popular understanding of science and mathematics were much better. But at the very least we have to avoid the catastrophe of a generation of students having to waste their time learning and later unlearning misconceptions about a non-existent "controversy." It would be far better for creationists to pull their kids from biology class than to muddy it up with their pseudoscience.

I believe the answer to this is that Kuhn is being used as a "fence" around this discussion.  To say that "Creationists would be within their rights to say "fine; we don't like that social practice and we prefer another". is really incomplete.  All the arguements I have heard from that side say that creationism, ID, whatever, IS science and needs to be included as such.
I guess I also have difficulty with "social practice".  Maybe I'm not schooled in this area well enough, but I think that putting ID on the same footing as (and within) science lies in the same realm as the national news media giving "equal time" to the Swiftboaters for Truth simply because they have a different opinion.  Is there a "legitimicy factor" in the definition of "social practice"?

Ptolemy's method of fitting the data with epicycles (basically "wheels within wheels") can fit any data.  While this wasn't conclusively proved until Fourier, it was long suspected.  Ptolemy came up with a Rube Goldberg machine, which was a useful calculation tool (for predicting eclipses and the positions of planets), but it had no explanatory power.


Copernicus' original model didn't fit the data as well as Ptolemy's, but it was vastly simpler.  And working scientists' other principle, that they value even more than falsifiability, is Occam's Razor.


You could add epicycles to Copernicus's model as well, but you need fewer of them and they take a regular form.  I suspect that Kepler was fooling around with epicycles when he hit on the right answer, that planetary orbits are ellipses.


Ever since the Copernican Revolution, scientists have been worried about overfitting the data, so a key test is whether a theory can fit data that was not known, or at least not used, when the theory was formulated.   Ptolemy's system would completely fail such a test.

It's true that when NASA calculates a launch, it uses Newtonian calculations. And they work fine. But the theory underlying those calculations is simply wrong.

Oh boy, did you open a can worms there. LOL I wonder how long it will be before this shows up again.

Secondly, ID is transparently an ideological halfway house.  It's an admission that physical science and the scientific method can no longer be rejected by the Creationists.

Exactly! Reading the recent NYT articles on ID gave me what I think is an important insight: the "irreducible complexity" folks such as Behe and Dembski all talk about design and components. Now you can read this and  let yourself get caught up in wheels within wheels, which is the rhetorical intent; alternatively, you can look for falsifiable hypotheses and refute them, and "mathematical ID" is especially vulnerable since it purports to be falsifiable.

But I have a better idea. Why not gloat? Surely there's time for a little victory dance. I mean, did I hear it right or did the vitalists just offer unconditional surrender to the materialists on the front page of the NYT? They agree that the transformation from a single cell containing DNA to a complex organism requires nothing but the physics and chemisty inherent in the system. This is an amazing admission. I mean, there is no scientific proof for it. It was a contentious point until quite recently, and has been the subject of debate for millennia (see Lucretius and others).

We're only beginning to unravel the physical processes of biology, and it's quite counterintuitive. We know that DNA encodes protein, and that a leopard has spots, but that's a far cry from understanding what changes to component proteins give spots instead of stripes. And that might be one of the simpler questions of morphogenesis. We can tweak fruit flies genes to get legs instead of antennas, but don't have film footage of what happened in between. So there are tons of gaps here. Once it was shocking and nihilistic to reject vitalism and propose that living things are in effect elaborate machines. But the "elaborate machine" theory has tons of gaps. Isn't God in those gaps?

Scientists are not primarily in the business of refuting religious belief, but scientists who happen to be proselytizing atheists (there are some but not so many as creationists think) may find a handy arsenal in science. What I say is this. If religious zealots want to pick a fight by looking for God in the gaps, why should we let them choose the gappiest bits of science. Interpreting the fossil record is like doing detective work only without the body. Why don't they pick some gaps in molecular biology? There are plenty of gaps there. Could it be they're chicken? Could it be that they are less likely to dismiss as "blind faith" those hypotheses that might actually be confirmed in the lab and published in next month's Nature?

Maybe we really need a counteroffensive at this point. Instead of focusing on underdetermined science, let's focus on the falsifiable underpinnings of religious belief that have since been proven false. Because there are tons of them. Bring the rumble to our turf. I mean, it's not really in my nature to rub people's noses in it, but the fact is that the material worldview has basically won every dispute thus far.

I think you're talking some kind of post-Kuhn dialectic here.

You: 

The old geocentric model of the universe fit the existing astronomical data better than Copernicus' heliocentric model.  And in fact, contrary to popular mythologizing, the data fit the old geocentric model well into Galileo's time.

In fact, what Kuhn says is that unresolved problems rise to the level of counter-example of the current paradigm rather than as problems to be dealt with.  This is what Chapter 7 is about.

Kuhn: 

On the contrary, what we previously called the puxxles that constitute normal science only exists because no paradigm that provides a basis for scientific research solves all the problems....(E)very problem problem that normal science sees as a puzzle can be seen, from another viewpoint, as a counter-instance and a source of crisis.

 "Better" is a normative term here.  The question is what failures of data evidence matter, and the degree to which they matter. The claim that elements outside the evidence plays a role (Einstein's famous "So much the worse for God, then" comment comes to mind.) is, I believe, not Kuhn's.

He does point out that there was, for example, a period of time where Newton's theories were performing pretty poorly in settled areas of research. But he doesn't claim the continued acceptance in the face of that poor performance was due to extra-scientific evaluation criteria, such as elegance. Rather the ability of Newton to explain previously untractable problems led to a commitment to a new paradigm, and converted those things that Newton couldn't explain into the "puzzles" of normal science, rather than the "counter-examples" that lead along with a new theory that explains the counter-examples to a paradigm shift. 

He makes a major point (which I think is the ultimate source of your view that elegance or some other criterion playes a role) that it is not enough to have counter-examples. The contrary evidence won't be seen as counter-examples until the new paradigm recasts them as such. You have to have the theory and the problems at the same time to get a paradigm shift.

The Lorentz transformations were normal science, resolving the problems presented by the Michaelson-Morley experiments.  Special relativity was a paradigm shift that recast those experiments as a counter-example, while retaining the Lorentz transformations as a tool inside the new paradigm.

Sundog,
Philosophy is, in part, an ongoing, 2500 year old conversation about what we can be said to know- the limits of what we can know. At it's best it can help temper some of the one-sidedness that we usually bring with us in our understanding of the world.

Even science can be one-sided in its attempts to limit the sphere of what can be known or said to be true to empirical-testable statements.

I think the days of grand metaphysical speculation are probably over. But post metaphysical philosophy can still help us examine our use of words and concepts and point out contradictions.

I think Matt's post here is a good example of the contributions a philosopher can make to ongoing controversies like this ID thing.

Our frustration with ID shouldn't make us so defensive that we retreat into a positivism that excludes much meaningful and needed dialogue that cannot be put into an empiricist straightjacket.

avatar

I don't get the joke. Are you saying that because the calculations work, the theory is right?

avatar

That's the way science works. It starts with a theory, possibly incomplete.

Not that I disagree with this general overview of scientific practice, in very broad terms, but it's equally reasonable to say that science starts with data, and attempts to fit explanations to it. This view goes back to Francis Bacon and still has adherents today. (I don't know how or whether this is relevant to Kuhn's views; it's been too long since I read him.)

avatar

Our frustration with ID shouldn't make us so defensive that we retreat into a positivism that excludes much meaningful and needed dialogue that cannot be put into an empiricist straightjacket.

 

You're really missing the point here, in my humble opinion.

For instance, are these statements "philosophy"?

1. Intelligence doesn't "appear" at a late stage of evolution. It seems to be inherent in nature.

2. Before there is intelligence in action, there is the potential for intelligence. This must precede the Big Bang and still exists at a subtle level of Nature.

3. The primary evidence for intelligence in the universe isn't design but consciousness. In some mysterious way Nature knows what it is doing.

4. Chaos and orderliness coexist, one being necessary for the other.

5. Evolution manipulates chaos the way an artist manipulates paint, to turn basic ingredients into complex forms.

6. Consciousness may exist in photons, which seem to be the carrier of all information in the universe.

7. The creative principle is eternal.

 I say no, obviously not. This is "pop" philosophy with pseudoscientific babble thrown in to make it palatable to the people who don't know science but who feel better if they hear a "science word" here and there.

This is akin to wondering if atoms are really tiny solar systems. It's just complete nonsense. It's stuff to discuss over a bong in your dorm room.

If you are asking me to take this stuff seriously, if you are implying that these are valid philosophical points and that Science is foolish to dismiss them, then I'm sorry, we have an intellectual disconnect that I don't see how to overcome.

The theory is right because its predictions match observation to measurable precision within the applicable domain.

What part of this could be wrong? There may be some misconceptions about "why" certain things predicted by the theory happen that way, but science in the current sense doesn't really deal with the question of why. Classical physics is a perfectly valid theory of how dynamic systems behave within a useful range.

If that's true, so are epicyles. Both will give you good results up to a certain precision, though the reason behind it turned out to be wrong. So what's the difference?

Science does indeed sometimes deal with "why". Why do the planets move as they do in the nighttime sky? Because they travel in ellipses. Why does gravity work? Because of the shape of spacetime.

avatar

Matthew,

Your last sentence says it all! Philosophical and theological discussions and musings are fine, but they are not science. Enough said.

avatar
In fact, if it can't be expressed in scientific terms, if theories can't be formulated and experiments can't be designed to test it, it isn't worth even discussing, unless you are satisfied with the sky-castles of philosophy.

Wow. That leaves, uh, let's see... most of life! What is love? What makes a work of art "good." Why does my boss have to be such an annoying jerk -- THAT LAST ONE WAS PURELY HYPOTHETICAL, STEVE.

Seriously, tone down the rhetoric, man. I personally think that epistemology is fantastically interesting and worth talking about, and directly gets to questions about the difficulty with people, even scientists, thinking they know what is "really real." You don't have to agree, but if you want to people to respect the social norms of science it would help to show respect to other social norms, like not knocking other peoples' beliefs as foolish (saying they're not science is fine).

avatar

If that's true, so are epicyles. Both will give you good results up to a certain precision, though the reason behind it turned out to be wrong. So what's the difference?

An epicycle theory isn't minimal, but it's not obvious to me that it is not "true". Actually, models with epicyles can be more useful than the pure theory. For instance, it may be more convenient to shift to a coordinate system in which the earth is stationary and contend with coriolsis forces, depending on what you're trying to calculate. Obviously, scientists adhere to Occam's razor and prefer simpler theories that explain the same observations. But when one model that made accurate predictions is replaced by another simpler one, the usual conclusion is that the new one is better, not that the old one was false.

Why does gravity work? Because of the shape of spacetime.

In this case, the "shape of spacetime" is itself an abstraction only meaningful insofar as it is a way of making verifiable predictions. For spacetime literally to have a "shape" in the intutive sense almost requires it to be embedded in a higher-dimensional flat Euclidean space. Far from explaining the why of anything that would just seem to defer the question. In fact, there's a theory that matches some observations. We use the word "shape" to describe part of the theory only because it's a way to grasp it in our mind, not because that explains anything.

BTW, in very conventional classic physics you can shift to high-degree coordinate systems. A system with n degrees of freedom can always be thought of as particle with a trajectory through n-dimensional space. We may consider the theory dealing with a such a particular to be both true and nearly minimal in the sense of Occam's razor, but we also understand that the n-dimensional space is merely an abstraction. The use of such abstraction is so commonplace that it is dangerous to try and evaluate theories in terms of whether things "really are" that way and only obviously meaningful to focus on prediction and confirmation.

avatar

No I am saying that because the calculations work and the theory is wrong, IDers will say that the observations on evolution are correct, but the theory is still wrong, just like Newtons were on gravity.


IMHO ID is a a wedge issue designed by the people who fund other extreme right wing causes that use propaganda to influence the electorate. It is emotional, reduced to simple phrasing, and easily repeated, and diparages intellectuals. Sounds like Mein Kaumpf to me.

avatar

The theory is right because its predictions match observation to measurable precision within the applicable domain.

An alternative view is attributed to George Box: "All models are wrong. Some models are useful." He was talking about statistical models rather than scientific theories, but I think the general idea is the same. All theories are contingent, and at some point the mapping between the theory and the real world breaks down, if for no other reason than that theories have limited scope in their descriptive and predictive abilities. (Not that I think most practicing scientists hold this kind of radical scepticism in the front of their minds as they're working, and I certainly don't think ID deserves serious scientific attention, but if we're outside the realm of logic, a theory is always open to question in principle.)

avatar

Wow. That leaves, uh, let's see... most of life! What is love? What makes a work of art "good." Why does my boss have to be such an annoying jerk -- THAT LAST ONE WAS PURELY HYPOTHETICAL, STEVE.

Nope, sorry. Those things - except perhaps the bit about your boss - are perfectly explainable by science. No mysticism needed.

Some people have this confused idea - "there are things science can explain, and things it cannot."  IMHO, that is merely muddled thinking. There are things science can't explain yet - that is all.

I apologize if my point of view offends you. A strictly skeptical worldview seems harsh to some; it's really not. I just spent my childhood and youth being fed phony answers; I don't settle for anything but the real thing now, and there's only one place to get that.

 

avatar

For instance, it may be more convenient to shift to a coordinate system in which the earth is stationary and contend with coriolsis [sic] forces, depending on what you're trying to calculate.

Oops, that should be coriolis. But to put it another way, I wouldn't argue about the "truth" of an epicycle theory if the guy at the other end is aiming long-range artillery.

avatar

Well, now, I certainly agree that there is no set of equations explaining gravitation that rise to the level of fact. And I certainly agree that within a certain domain the Newtonian equations work fine.

But I also know that the domain of events that Einstein's equations can describe contains Newton's and includes events that are within Newton's that Newton's equations can't explain (unless you define Newton's equation's domain to be those events that his equations predict accurately, in which case I have my own theory of gravitation involving my dog and a collection of objects that have different degrees of gravitational force.)

So I'm content in saying that Newton is wrong--that there are events that are part of his domain that he cannot predict accurately.

avatar

It no longer matters if the theory is right, a credible scientiest has already stated that it was wrong.


This isn't about science and it isn't about religion, ID is political manipulation.


All the bullshit posted on this thread is not going to translate into simple sound bites that the non scientist, non political animal can sink their teeth into. Godless Scientist, Atheist Scientists, Religious Bigots all do, and they may very well be true, and they damn sure translate into energizing the base of the Republican party. All this fine edumacation on display, and no one has a clue.


If this all Josh and Matt have got to write about maybe they ought to switch careers or parties, because they ain't helping the Democrats.

avatar

So I'm content in saying that Newton is wrong

Me too, but only because he didn't set the right restrictions on the applicability of his theory or assign the right error bars. But Newtonian physics as now understood is by all evidence a true theory.

avatar

One way to think about the right's attempt to politicize science is the various ways they label the scientists they disagree with, issue by issue.

Evolution - scientists who only want evolution taught in classrooms are easy targets.  They are atheists, agnostics and secular humanists (translation: liberals).  Moreover, they are elitists who would tell Americans how to teach their children.

Global Warming - scientists who claim global warming exists are radical environmentalists, conspiracy buffs, and alarmists.  They intentionally muddy their results to further their agenda or overreact to insignificant data.

Food Science - vegetarians and obesity alarmists who hate corporations and want to tell Americans what to do.  They hate freedom and your spoiled, fat little kids.

Social Sciences - a no brainer.  Everybody knows American universities have been infiltrated by leftists, god-hating liberals.

When you look at the big picture, you see that it's not just science under attack.  Republicans are trying to undermine something even more fundamental: the idea of mutally agreed upon, objective facts.  Science can't be trusted.  All journalism is biased.  Universities are infected with liberals.  There is no objective truth.  Believe in mysticism.  Believe in conspiracy.  Question everything you see in the media, regardless of its source.

The more the concept of mutally agreed upon, objective facts erodes, the easier it becomes for the GOP machine to influence things using money and propaganda.  On every level.  People who believe nothing can be convinced of anything.

I guess I also have difficulty with "social practice". Maybe I'm not schooled in this area well enough, but I think that putting ID on the same footing as (and within) science lies in the same realm as the national news media giving "equal time" to the Swiftboaters for Truth simply because they have a different opinion. Is there a "legitimicy factor" in the definition of "social practice"?

Well but I think Matt's point is that ID is a social practice separate from science, that it does *not* fit within science. 

The comparison with the Swiftboaters for Truth campaign hints at a common, and in my opinion, flawed, interpretation of... hmm...  references to the social world, I guess?  On one side of this misinterpretation are those relativists who seem to think that all social practices are of equal value -- or to put it another way, that the question of a practice's value is meaningless.  On the other side are those scientists who seem to think that describing a practice as "social" is a kind of slur -- it marks a practice as less pure, and, well, sort of fake, compared to "real" science. 

In my opinion, neither side of this divide is accurate, because -- going back to your comment about the Swiftboaters' "legitimacy factor" -- calling something a social practice has nothing to do with its legitimacy.  It does not grant equivalent legitimacy to all such practices, as some relativists may suggest, nor does it automatically de-legitimize such practices, as some scientists may suggest.  Legitimacy is a separate (and meaningful -- contrary to how some relativists would have it)  question. 

But it's not really necessary to go to the legitimacy question to make the point that ID shouldn't be taught in public school science classes -- it's only necessary to point out that it's not science.  You could compare it to attempts to teach non-science social practices of various degrees of legitimacy in a science class -- like, say, yoga, a practice that, while it is not science, has, in my opinion, a great deal of legitimacy.  Or say, socialist ideology, a practice that is not science and that, in my opinion, has little legitimacy.  In both cases, putting the question of legitimacy aside, we can clearly say that doing yoga is not doing science, and doing socialism is not doing science.

Sundog,
Those enboldened statements are maybe better said to be the sort of statements that both scientists and philosophers might want to take a critical look at- each in their own way.

I'm not a defender of ID. Far from it. What drew my attention to this post and string of comments was my sympathy for what I saw to be Matt's point- which I tried to paraphrase in my own far from perfect way in my statement about frustration and straightjackets- that scientistst sometimes overstep the bounds of reason by using "positivistic" type reasoning in their arguments against ID. Hence that little jab at what I saw to be a contradiction in your earlier comment.

So, when it comes to criticizing ID- I'm on board. Though I do wonder what folks who are sympathetic to ID get out of it in terms of meaning. My speculation is that some folks feel threatened in their identity as persons somehow by evolutionary theory. And I think that positivism tends to feed that sense of threat. So I think that positivism might be a problematic  philosophy of science and also might be part of what feeds the fuels of distrust of science. But that's just my meager attempts to work out why ID finds a home in the popular imagination. And that's a different concern than the argumentation against what passes for ID theory that you are interested in.

avatar
Nope, sorry. Those things - except perhaps the bit about your boss - are perfectly explainable by science.

Science can explain relative aesthetic judgements?

Some people have this confused idea - "there are things science can explain, and things it cannot." IMHO, that is merely muddled thinking.

IMHO, your assertion here is itself muddled. Relative aesthetic judgements, ethics, speculative questions like "what existed before the physical universe we can observe" are all completely outside the domain of science. The last may be dismissed as irrelevant, even if it's an interesting question to some. The first certainly cannot be dismissed if one's profession is in the arts. The second question is of profound importance, even to scientists (e.g., "is it ethical to clone people?") despite the fact that science cannot provide an answer -- "is it ethical" is not a question which can be answered using the tools of science. The answer depends entirely upon the interplay and relative weight of certain sets of cultural values, and there's not one "right" answer other than whatever consensus society can arrive at.

The underlying issue of the WWJD-ID debate is simply anti-intellectualism, and has nothing to do with the silly specifics of this revision of ID theory. As a belief system, it doesn’t even have the sophistic appeal of deconstructionism for example.

ID is simply a computational failure. It's the "I give up" theory. It’s intellectual laziness, combined with fancy, familiar to every cartographer who ever wrote “beyond here be dragons.”

avatar

All the bullshit posted on this thread is not going to translate into simple sound bites that the non scientist, non political animal can sink their teeth into.

Here's one problem: What are Republicans selling? Certainty. Owenz gives a nice list. What do people read in the papers instead about scientists? "Scientists discover previously unknown X," and "New theory in X contradicts previous thought". It's in the nature of science to question received wisdom, but the process doesn't lend itself to sound bites. People don't like uncertainty. Given a choice between believing a religious leader or book that presents eternal truths, in contrast to a scientist who doesn't even speak the same language in explaining things, of course people are going to go with the former.

Solutions are not easy. Here are a few obvious possibilities, none of which seem especially workable:

  1. Push the authoritarian slogan, "Leave science to the scientists." Or at least try to convince people that scientists should be trusted when they say something abot their field.

  2. Improve science education (but how?) enough to convince people that conflicts with their religious beliefs should be resolved in favor of what works in the real world.
  3. Give up on Kansas, and take our knocks.

I don't like any of these choices. I'm sure there are others, but I come back to the thought of how Copernicus might have convinced his contemporaries that his theory about the solar system was correct, even though it removed humans from the center of the universe and cast doubt on a great many other beliefs by implication. We probably think, "Given the influence of religious thinking at the time, Copernicus hardly had a chance, at least in the short term." How different is it today?

avatar

Science can explain relative aesthetic judgements?

Evolutionary psychology, at least in the abstract if not as now practiced, could probably tell you a lot about the human perception of beauty, though it might be hopeless to carry it down to the individual level.

avatar

though it might be hopeless to carry it down to the individual level.

Not necessarily. Aesthetic judgment is certainly open to empirical analysis:

Ramachandran, V. S. and Hirstein, W. 1999. The science of art: A neurological theory of aesthetic experience. J. Conscious. Stud. 6, 6-7, 15-51.

(I should say that I haven't read the article myself, but know it only indirectly through the work of a colleague, so there's no endorsement implied. My colleague's work looks at correlations between low-level visual features and aesthetic judgment of artificially generated scenes.)

Let me know when we have any significant results from philosophy.

Let me know when we have any significant results from science. Your satellite radio was created by an engineer, not a scientist. I took personal offense to your comment, as someone who has degrees in philosophy and electrical engineering.

Philosophers of science often smirk at scientists who have an unsophisticated view of the philosophy of science. Most seem to subscribe to Popperian ideas of falsifiability distinguishing science and pseudoscience. Meanwhile, scientists and mathematicians look at engineers and scoff at engineers' unsophisticated understanding of modern science and mathematics.

By the way, philosophers make plenty of contributions to computer science, artificial intelligence, and legal academia, among other fields.

The post-modernists use him to say "even science is post-modern."  Well, to the degree anything is, science is the least of the post-modern disciplines. And it's pretty funny that the wingnuts choose that discipline to haul out the post-modern carbines.

Well put. Excellent lead-up and closing line.

We were playing with Zen Koans the other day, and this one seems appropriate again:

Hogen, a Chinese Zen teacher, lived alone in a small temple in the country. One day four traveling monks appeared and asked if they might make a fire in his yard to warm themselves.

While they were building the fire, Hogen heard them arguing about subjectivity and objectivity. He joined them and said: "There is a big stone. Do you consider it to be inside or outside your mind?"

One of the monks replied: "From the Buddhist viewpoint everything is an objectification of mind, so I would say that the stone is inside my mind."

"Your head must feel very heavy," observed Hogen, "if you are carrying around a stone like that in your mind."

 

avatar

Relative aesthetic judgements, ethics, speculative questions like "what existed before the physical universe we can observe" are all completely outside the domain of science.

This sentence nicely defines the problem.

In your view, consciousness and the associated questions arising out of it are some sort of spiritual phenomenon. A critical thinker rejects such a supposition. There is nothing that is "outside the domain of science." The very idea is nonsensical to one who trusts the scientific process.

Further discussion will get us nowhere, because you either don't understand or don't believe in what science is about.  I would not be so arrogant as to instruct you in what critical thinking is all abut, but you might find it an instructive course of investigation.

Wow...great conversation.


To use Occum's Razor on ID it is easy to see why it should not be taught as "science".  The whole argument of the ID'ers is that since the universe is so complex and can't be completely explained it can therefore be said that a higher form of intelligence/life created all we see.  The problem is the proof is not quantifiable by observation.


It is like Ed Witten's great work on "String Theory".  Witten worked out the math showing that there probably many different dimensions (over 10) in the universe that exist even though we can not perceive them using our senses, as proposed in the String Theory.  Until it can be quantified, by observation, that these other dimensions exist it is impossible to prove or disprove the String Theory.  That means, although it might be true, it is more philosophy then science, just like ID.  Therefore the existence of over 10 dimensions in the universe shouldn't be taught as scientific fact just as ID shouldn't...

avatar
Not necessarily. Aesthetic judgment is certainly open to empirical analysis

Sure, an impoverished analysis. A text on neurological systems might tell you what is going on in the brain when you see certain figures/colors, etc. Evolutionary psychologists might be able to explain why certain colors evoke certain emotions more often then others, but neither of these things can answer questions like "how skilled is this painter vs. this other painter" or, more fundamentally, "what is the artist saying?" or "is it good?"

avatar

Let me know when we have any significant results from science. Your satellite radio was created by an engineer, not a scientist.

 

Heh. Someone else smack this one out of the park; I'm tired of trying to explain what science is.

If you are offended by anything I have to say, I request that you simply ignore me from now on. This is an intellectual discussion and your personal feelings are irrelevant.

Sundog - one point which you might be missing is that philosophy is necessary to make the sort of intuitive leaps that for example led Einstein to his discoveries. Philosophy is not just "sky castles" it's an exercise in attempting to frame the unknown using.

For example, here is a philosophical issue regarding animism, which goes to your initial posts. Where does life originate? What lives? Those aren’t questions we have to ask. But, if we ask them, they lead to theories, experiments, and eventually usable technology.

For example, are we simply the sum of our material parts? Where then does our consciousness come from? Does life exist in all things? Is consciousness simply something which occurs when a pattern is formed in unconscious inanimate matter? How does life self assemble? Are there principles which can be extrapolated into manufacturing on the nano-scale for example.

Taking that further, can man construct life in the lab? How about mad made living things constructed on the molecular level from inorganic matter? If those were assembled into something as complex as a sheep or even human being, is it alive? Conscious? At what point? Can it be tested? Those questions have direct implication for bio-ethics and shape research and discovery today for example.

avatar

Sure, an impoverished analysis.

That's meant to be pejorative, I guess, but science is all about boiling down questions to the essentials. As for the examples of judging whether a painter is good or not, or what an artist is saying--what takes these beyond scientific analysis? Suppose that I could build a machine (my background is in artificial intelligence) that produced statements when shown a piece of art that fell within the variation of human subjects when shown the same art? My machine would at least implicitly (some would even say explicitly) embody a theory of aesthetics.

On the production side, there's Harold Cohen's Aaron system, of course.

But I suppose we're straying pretty far from Kuhn and ID.

avatar

Nick, those are of course good points. I am confusing my personal disdain for philosophy with my disdain for how Chopra is abusing it.

In my mind, philosophy is good for just that: formulating questions. But it never seems to provide answers. That's fine, I don't think it's for getting answers.

But the stuff Chopra is peddling is not philosophy, in my mind. It is just sheer speculation backed by nothing but air. And it offends me mightily that he wraps it all up in a package with patently absurd pseudoscientific ideas and hopes we'll swallow it.
