Defending Philosophy of Science, Conclusion

Here is the messy conclusion to the thread on the applicability of Philosophy of Science:

Johnny, I hate to join in this debate, as I’m not very interested in Philosophy of Science, but could you please read these questions again and answer them properly:

>Lolawalser:Next, is your contention that biochemistry and applied sciences have laboured all this time employing methods without the backing of “sound theory”? If it is, can you show it is true?

Let me simplify: do you think that all the achievements of biochemistry etc. have been serendipitous, discovered by methodologically blind people groping around?

You replied

>johnnylogic: theory may allows us to systematize, optimize, predict and control where we could not do so before.

Does that mean biochemists operate without any knowledge of biochemistry (which is the so-called “theory”)?

Does that mean they have not been capable of systematizing, optimizing, predicting and controlling anything before?

Do you realize how absurd such an argument sounds?

>Lolawalser:Now, assuming that it is true (to speed things up–I personally think it’s a ridiculous statement–Not Even Wrong), what does it tell you, if the achievements of science so far have been produced “without” the backing of sound theory–such as you envisage?

You did not reply to this question, but never mind.

>johnnylogic:What makes you think that science as currently practiced is optimal? How would you suggest our methods be improved, if not by reasoning about and a theory of its methods? This is just PoS.

Why do you think the enhancement or correction of methodology belongs to some metaphysical or “logical” (analytically) realm? Does it occur to you that methodology comes about according to the nature of the experiment at hand, and that modifying or changing methods is inherent to the work of doing science itself, rather than requiring a philosophy of praxis as a crutch to fall back on?

Let me put it another way – say you are an inventor, with a concept but no tools or materials. What would be your first step? Do you sit down to “theorize” about the practice of building? Or do you familiarize yourself with the science or engineering required, try to make an educated guess about what you need based on your learning and experience, and attempt to build your concept? And when aspects of your construction fail, or you realize what you have built is something different from the concept you envisaged, do you not automatically try other methods or expand your concept? This is a very simplistic example and I am no scientist, so someone can feel free to correct me here, but what I am getting to is that I think your ‘philosophy of (practice of) science’ sounds redundant to LolaWalser because it already is immanent in the act of doing science. Sure, you can specialize in a philosophy of a particular scientific method (but I don’t call that philosophy) when you are engaged with that scientific method, but do you realize how meaningless such a philosophy is by itself, as a field of its own, divorced from any reference to real data, actual experimentation, etc.?

>fluffy, pomo, intellectual onanism

These comments always make me chuckle, particularly in the light of tautological arguments with little or no definition of concepts, from allegedly critical, consistent and rigorous ‘philosophers’.

Yes, it is Existanai again; you may remember him from such threads as The Analytic/Continental Divide.

My reply and more below the fold:

Let me simplify: do you think that all the achievements of biochemistry etc. have been serendipitous, discovered by methodologically blind people groping around? Does that mean biochemists operate without any knowledge of biochemistry (which is the so-called “theory”)?

No. What reading of what I have posted would prompt these questions? Theory of scientific methodology, not an individual science. Science’s success has come with reflection about method (see Galileo’ or Newton’s writings for plenty of methodological talk) and it is certainly not serendipitous, but possibly suboptimal given the many outstanding methodological questions hanging about. Of course, how would we know if such considerations get shut down before we even consider them?

I have not claimed that there is a philosophical or theoretical prerequisite to doing science, just that it may help our scientific practice to reflect on and refine our methods with the logical, mathematical, and conceptual tools available to us.

Why do you think the enhancement or correction of methodology belongs to some metaphysical or “logical” (analytically) realm? Does it occur to you that methodology comes about according to the nature of the experiment at hand, and that modifying or changing methods is inherent to the work of doing science itself, rather than requiring a philosophy of praxis as a crutch to fall back on?

Where did you get “metaphysical” from? Replication would require us to be able to individuate components that do not magically arise from “the experiment at hand”. How are we to compare experiments and results without identifying relevant commonalities and differences? If we are to automate the practice, as is the goal in machine learning, we certainly must do more than wave our hands at context of experimentation and discovery– we are forced to model the process, which means using the aforementioned conceptual tools.

Wow–we have two people now that engage in debate, but are not interested in philosophy of science. Does anyone else want to try to satisfy this peanut gallery?

Existanai:

>Me: Does that mean biochemists operate without any knowledge of biochemistry (which is the so-called “theory”)?

>johnnylogic: What reading of what I have posted would prompt these questions?

This: “My point is that methods should be backed by sound theory.”

And this: “To quote a scientist, “There is nothing more practical than a good theory.”"

And this: “However, theory may allows us to systematize, optimize, predict and control where we could not do so before. ”

Etc.

Apparently it’s still not clear to you. If you need a good theory to to systematize, optimize, predict and control where we could not do so before, your implication is that 1) methods as they exist today are insufficient for the work of science, and/or 2) could be much improved, consequently leading to ‘better science’, and/or 3) there are some ‘a priori’ truths regarding science or scientific methodology, a la Kantian metaphysics, that determine the scope of what science can or should discover, and if these a priori truths are established, science will flourish, in whatever pre-defined way.

Firstly, you have not even attempted to explain what you mean by science, which is diverse by definition and by method. There is always crossover of course – you can study part of a tree bark at a subatomic (physics), molecular (chemistry – bonding etc.), or cellular (biology) level, but to state the obvious again, there is also enough distinction that an expert in quarks doesn’t become an expert in barks. What makes ‘scientific method’ in theoretical physics, which is often purely mathematical at first, has little or nothing in common with the scientific methodology of a botanist.

In the first case, if the current methods are insufficient, then that does not explain how science in whatever form continues to be effective, reliable, and in practice, so your suggestion is useless. In the second case, if you want to suggest ‘improvement’, then you can only do it through science itself, which in my opinion is well within the domain of science and not philosophy – you cannot establishes rules for botanical methodology through pure logic, and you cannot gather black holes and white dwarfs in a laboratory to carry out tests on them. Even assuming that you want to separate the thinking-through of methodology from science, and call it a philosophy, then such philosophy can only exist as a highly specialized field that supplements a particular kind of scientific research. Because when it’s decontextualized, it loses any meaning and value. Again, since you have not attempted to define anything, I can only assume that by philosophy you mean the current academic practice, and not all of philosophy since the start of recorded time.

If, however, you think a philosophy of science can and should transcend the work of science, that its ideas or principles are above and beyond specific, topical methodology, then you are merely engaging in metaphysics. Whatever the philosophical value of Kant etc., I think anyone who even vaguely remembers science from their school days should understand that a search for ‘a priori’ principles of knowledge are completely redundant and unnecessary where the work of science is concerned, as evinced by the existence and effectiveness of all of science itself. A physicist does not need to know whether a reality exists within or beyond the physical reality he is studying, or an ulterior knowledge exists beyond his physics, because they have no bearing at all on his study, reasoning or conclusions, which are in any case self-consistent. Whatever the philosophical implications of such a rejection, they don’t matter to physics because physics is defined by restricting itself to the observable, palpable, testable, and so on. So a hunt for such transcendent principles is utterly pointless.

All the examples you have provided, of recent philosophers having a dialog with and ‘aiding’ scientists, is merely the critical thinking of one person coming to the help of another, an example of seeking other ways of approaching a problem, other opinions, even from outside one’s field in the hope of breaking out of one’s own limited approach – because everyone’s mind is limited in some way and requires a little inspiration or shaking up once in a while. This, for you, is academic philosophy, but not for me – it is philosophical, certainly, but no more or no less than what non-philosophers are capable of (a point I have made before.) To oversimplify the point greatly, there is the famous anecdote of Kekule making a breakthrough with the structure of benzene, establishing that it was a ring of carbon, a notion that apparently came to him when he dreamt or thought of a snake eating its own tail; based on such an anecdote, however, I wouldn’t really want to hypothesize about the usefulness of dreaming to science, although I’m sure there’s a little history of that too.

>Where did you get “metaphysical” from?

See above.

>Theory of scientific methodology, not an individual science. Science’s success has come with reflection about method (see Galileo’ or Newton’s writings for plenty of methodological talk) and it is certainly not serendipitous, but possibly suboptimal given the many outstanding methodological questions hanging about. Of course, how would we know if such considerations get shut down before we even consider them?

Galileo and Newton were establishing a foundation for further work, or defending themselves against arbitrariness and untested faith, so your example is redundant (like your earlier examples). Since the beginning of this thread you have been conflating the historical practice of science, ancient philosophy, the foundations of modern scientific method, and mostly contemporary academic philosophy, when doing so makes the very premise of your argument invalid because you can then equate almost anything in philosophy before 1800 with almost anything in science before 1800. As we’re all aware these fields were not even distinct until two to three centuries ago and even now, people like yourself insist on there being underlying principles or ‘commonalities’ when the world is perfectly content to operate with complexity and diversity and difference. Why is that so hard to accept?

>If we are to automate the practice — we are forced to model the process, which means using the aforementioned conceptual tools.

Why automate anything? I’ve answered this too above.

>it may help our scientific practice to reflect on and refine our methods with the logical, mathematical, and conceptual tools available to us.

A philosopher or series of philosophers or scientist arguing for carefully established rules of method does not convert ‘scientific methodology’ into philosophy any more than the original, philosophical hypotheses about the universe make astronomy a philosophical or humanitarian field. We are covering the same ground again: if you do want to call all critical thinking philosophy, then science and engineering and architecture and even, say, manufacturing or industrial design are ‘philosophy’, or at least their ‘theoretical’ parts are. And if they are not philosophy, then you have to stop and define the differences, as any non-fluffy, non-onanistic philosopher is expected to do. And yet again, if the question is irrelevant, we are free to call both critical thinking and the current academic field philosophy. And you should not be insisting on the importance of ‘philosophy of science’ as something above and beyond the work of science itself, or we will soon also need a ‘philosophy of sports’ to tie up all critiques of sport with the sports themselves, to ’round out’ the athletes and further modify the ‘underpinnings of their applied technique’.

———————————————–

In brief, your argument is weak if not terrible. It’s certainly not up to the high standards of ‘logic’ you’ve set up, as evidenced by your dismissal of so-called ‘pomo’ figures.

And since we are only going round in circles, let me offer you a way out with a cue from the fluffy onanists:

At what point can critical thinking about a subject be said to have become systematized? In other words, at what point along the way from the ‘naive’ biology of Aristotle to the current science of biology did observation and inference establish a model called science? In what category should we place medicine, or psychology, if they both rely on scientific method but do not have the consistency or predictability or blunt applicability of other sciences?

These are interesting questions about science that, on the one hand, require a knowledge of science and, on the other, do not try to take the place of science but merely offer a perspective or history of it, and attempt to investigate cultural and other issues that may or may not be of scientific concern. These are some of the types of questions attempted by the so-called post-modernists you look down on, and, even if one does not agree with their conclusions, their arguments are far more sophisticated and mature in that they do not attempt to pose as an essential part of science or claim to be ‘aiding’ science. If they do end up aiding science, that is incidental, not a call for the creation of a new faculty at universities.

If the above is what you mean by “philosophy of science” – or perhaps questions concerning bioethics, or the role of political manipulation of science to serve right-wingers, etc. then yes, there is a “philosophy of science”, that is of some interest. But it certainly doesn’t exist as a template for all science – there are no Forty Seven Commandments or whatever.

>Does anyone else want to try to satisfy this peanut gallery?

The ‘peanut gallery’ does not seek satisfaction but, at the very least, a well-exemplified, well-reasoned and non-tautological argument from self-professed philosophers or philosophy hobbyists.

He has a mighty big chip on his shoulder.

My reply:

My statement about “fluffy pomo onanists” was meant in parody of a mistaken view of philosophy, so try not to take it personally; I do not dismiss “continental” philosophy the way that you dismiss analytic philosophy.

Firstly, you have not even attempted to explain what you mean by science, which is diverse by definition and by method.

I have (see #33). You have chosen to overlook it. I am not interested in giving the sufficient and necessary conditions for membership in the set Science.

What makes ‘scientific method’ in theoretical physics, which is often purely mathematical at first, has little or nothing in common with the scientific methodology of a botanist…etc.

Really? Is human reasoning so heterogeneous so as to not admit any common description? I’m not suggestion some totalizing, once-and-for-all purely logical characterization of science. I’ll settle for understanding parts, as we can.

Even assuming that you want to separate the thinking-through of methodology from science, and call it a philosophy, then such philosophy can only exist as a highly specialized field that supplements a particular kind of scientific research. Because when it’s decontextualized, it loses any meaning and value.

Is this true in all contexts?

All the examples you have provided, of recent philosophers having a dialog with and ‘aiding’ scientists, is merely the critical thinking of one person coming to the help of another, an example of seeking other ways of approaching a problem, other opinions, even from outside one’s field in the hope of breaking out of one’s own limited approach – because everyone’s mind is limited in some way and requires a little inspiration or shaking up once in a while. This, for you, is academic philosophy, but not for me – it is philosophical, certainly, but no more or no less than what non-philosophers are capable of (a point I have made before.)

If by science you mean all the methods of mathematics, logic, experiment, and critical thinking in general, then I guess we have to do it through science. Nothing like forcing the answer definitionally! Who’s being tautological? The activities of institutionally and self-described philosophers in following their line of inquiry are not doing philosophy; they are just critically thinking. OK. I am just interested in the questions. I don’t care what label you give it.

As we’re all aware these fields were not even distinct until two to three centuries ago and even now, people like yourself insist on there being underlying principles or ‘commonalities’ when the world is perfectly content to operate with complexity and diversity and difference. Why is that so hard to accept?

I am content with both difference and sameness– to the extent we find helpful similarities in method, we may systematize; where we cannot find common ground, we wont. I am no enemy to diversity. Good strawmanning, though.

>If we are to automate the practice — we are forced to model the process, which means using the aforementioned conceptual tools.

Why automate anything? I’ve answered this too above.

There are very good practical reasons to automate scientific processes, including the production of expert systems for diagnostics, AI for exploratory satellites and robots (NASA), filtering spam, etc. There are also good theoretical reasons, as programming theories of inference tends to make clear the assumptions being made, and reveal relevant constraints (computational, time, etc.).

>Does anyone else want to try to satisfy this peanut gallery?

The ‘peanut gallery’ does not seek satisfaction but, at the very least, a well-exemplified, well-reasoned and non-tautological argument from self-professed philosophers or philosophy hobbyists.

Happily, I do not see it my duty to convince you, when your conclusions is forgone. I have tried to provide examples of philosophers of science aiding science, historically, and contemporarily (which was the original question), but you have defined that possibility out of being; you selectively ignore the content of my posts and you fill the gaps in with uncharitable assumptions.

I have a more than full time job, a young child, and a fence in need of building, so I will leave you to dance with your straw men.

True to my word, Existanai has the last post:

>I am not interested in giving the sufficient and necessary conditions for membership in the set Science.

Not needed, but your definition as stated would apply to a number of things, such as architecture. Although I am no scientist of any stripe myself, I think you just don’t get how multifarious and complex the various sciences are, and speaking of them all together as “science” only makes one’s argument analogous to those of religious fanatics who lump everything outside religion as one great mass of heresy.

>Is human reasoning so heterogeneous so as to not admit any common description?

Again, human reasoning does not by itself constitute philosophy or require philosophy to exist.

>I’ll settle for understanding parts, as we can.

Well, good – learn and do science. Those are the ‘parts’ you speak of.

>Me: Because when (philosophy of science) is decontextualized, it loses any meaning and value.

> johhnylogic: Is this true in all contexts?

How many decontextualized contexts can you think of? Sorry – your question is so amusing I couldn’t resist. Seriously, how many cases can you think of where a philosophy of science as I described it, being an appendage to a scientific area of research and used by the particular scientists to think about their own practice, is meaningful outside of the particular scientific field?

>If by science you mean all the methods of mathematics, logic, experiment, and critical thinking in general, then I guess we have to do it through science… Who’s being tautological?

Again, you simply don’t understand that science is too much of a blanket term (and even as a blanket term, not well enough defined by you.) Each science will have its own approach, methodology etc. to solve its own kinds of problems, and it does not need to refer to a philosophy textbook to discover for itself what the most effective methods of investigation, research etc. are.

>The activities of institutionally and self-described philosophers in following their line of inquiry are not doing philosophy; they are just critically thinking.

No, this is what you fail to get again. If you are following a line of inquiry within certain bounds, well and good. If you are trying to wax poetic about already existing, self-consistent fields and offer pretty hypotheses with no practical/professional understanding of the field itself, in the hope that your pretty hypotheses are some day going to supplement, or ‘improve’, or reinvent some of those fields, then – to put it very gently – your ideas are as relevant as all metaphysical imaginings, and whether you are a philosopher or a waitress or a tennis player, your imaginings have equal weight (or lack thereof) to the science in question, and should not necessarily be considered representative of your profession :) .

Anyone can offer some valuable help to science. This does not necessarily make them de facto scientists, or philosophers of science, etc. whatever their professional designation. It does not necessarily elevate the ‘help’ to the level of science either.

>There are very good practical reasons to automate scientific processes

Sorry, my question was intended to be: why do you think you need ‘philosophy’ to automate anything in science? Why do you think science is deficient in creating its own solutions?

>I have tried to provide examples of philosophers of science aiding science, historically, and contemporarily

These examples are not what you claim them to be.

>I do not see it my duty to convince you, when your conclusions is forgone… I will leave you to dance with your straw men

This is quite amusing, because you haven’t even bothered to directly reply to many of the questions you were asked. This is especially ironic in light of the fact that as a non-scientist (like myself), heading a group of mostly non-scientists, about what you call the philosophy of science, you barely address any valid criticism from the only two or three scientists on this board. Never mind me – if you can’t convince them, and can’t post at least one clear example of the philosophy of science ‘improving science’, how much more progress are you going to make in the broader world? Do you always hope to appeal to people within the inner circle of your kind of reasoning? If so, why go to all the trouble of elaborating a ‘philosophy’ for the good of hundreds of other fields and millions of people all of whom you shoehorn under the label ‘science’?

The great strawman in all of your own arguments is that science as it exists now is incapable of devising solutions to its own problems, and somehow needs something ‘added’ to it, some ‘performance booster’ as it were – and that’s what your little philosophy of science is there to provide.

It’s not my duty to convince you either, but I at least offered ways for you to bolster your argument.

All of us have greater priorities, by the way. So, if I don’t hear from you – take care and have fun.

I am quite done with trying to explain my position to an unsympathetic bore with selective attention.

Defending Philosophy of Science

I seem to have a gift for being drawn into trenchant conversations. The latest involves the usefulness of philosophy of science:

I stated:

…normative PoS has little bearing on what we (a geotechnical engineering consulting firm) do. This worries me a bit.

LolaWalser, asked:

Why does this worry you?

I think that the philosophy of science should work to advance the sciences and, in turn, the sciences should take methodological recommendations (in part) from PoS. I see problems in both directions. I worry that philosophers, with some important exceptions, do not perform the requisite work to bring PoS into the implementation level, and scientists ignore the potentially helpful insights and recommendations of philosophers and other methodologists.

For example, many sciences need to select models (curves) from data in order to make predictions and make important decisions. Model selection is a nontrivial philosophical problem with practical consequences. The usual method in many businesses involves using Excel’s built-in curve fitting by selecting a trend line from a set of equations of varying degrees and eyeballing the fit. This is “good enough” in some ways, but it certainly could be better, given the research done in the subject, and given the problem of over fitting (that is, ramping up the number of parameters to perfectly fit the data as well as noise).

A great example of applied PoS is Causation, Prediction, and Search, Second Edition by Peter Spirtes, Clark Glymour, and Richard Scheines. Therein they set forth a formal theory of causal inference involving Bayesian networks. Blurb: “The authors show that the relationship between causality and probability can also help to clarify such diverse topics in statistics as the comparative power of experimentation versus observation, Simpson’s paradox, errors in regression models, retrospective versus prospective sampling, and variable selection.” The authors have (with the help of others) developed TETRAD– a software implimentation of their philosophical/formal ideas.

Your thoughts? Can/should philosophy of science be applied? How? Examples?

LolaWalser’s condescending reply and more below the fold:

I think that the philosophy of science should work to advance the sciences and, in turn, the sciences should take methodological recommendations (in part) from PoS.

Do you also think philosophy of art should work to “advance art’”? What about, um, the philosophy of LOVE and its subject? :)

Frankly (and I’m fairly sure I speak for a large number of my colleagues) I have no interest in philosophy of science–NOW, after 16 years of benchwork. Once upon a time, a gentler, high-schoolish time, I may have entertained some such notions of philosophy–well, not exactly “advancing” science (science has done remarkably well all on its own, pre- and post-Popper et al.)–but at least, I don’t know, mattering to it. As it turns out (she said, eyeing her Philosophiae Doctor wistfully), it doesn’t.

But perhaps I’m a narrow-minded intellectual hick–and after all, what’s true for my science/field may not be true for another. Still, as far as I can glean from my fairly wide trade reading (I have never in my entire professional career TALKED about PoS with my colleagues–nobody brings it up), it doesn’t appear scientists in general think PoS any more useful or pertinent than I do. What’s the problem?

Could it be that it’s naive, useless and ultimately simply wrong to imagine modern philosophers “advancing” science, because they seem to have no idea of the realities and practicalities of research?

scientists ignore the potentially helpful insights and recommendations of philosophers and other methodologists.

I’d love to see a demonstration of a real life example of a scientific study which would have profited from professional insight from philosophers.

If I need to learn better modelling or statistical analysis, I’ll turn to mathematicians; for help with experimental design, first of all to people with practical experience. I couldn’t begin to trust a person with no practical knowledge of experimental research (students, of course, are there to gain that knowledge). I couldn’t begin to trust someone who has had less math than I did (we might run into some geographical/national differences here as well… European scientific education, at pre-grad school levels especially, tends to be considerably more rigorous than the American one) and above all, did not use those skills in the situations I’m encountering.

Can/should philosophy of science be applied? How? Examples?

My answer: Doesn’t apply/Don’t know any. However! One way to determine whether PoS can contribute to science would be to have mature, finished PoSers (the more advanced their degrees the better) study science–go through the whole process, of course, grad school to postdoc to, ahem, probably another postdoc…

If these candidates perform significantly better than mere non-philosophical scientists (appropriately matched for age etc.–maybe also throw in a control group of, I don’t know, sociologists? art historian-scientists?–don’t want my experimental design called in question here!), your case is made.

A great example of applied PoS

I’ll look this up and report if I find a way to use it.

Lastly, I hope I didn’t sound unfriendly–and there was no intention to offend. Simply trying to convey a bit of your average scientific Joe’s view.

I tried my best to be civil in my response:

LolaWalser,

I had anticipated this sort of reaction from a scientist. Generally, there is a great deal of contempt for philosophy, perhaps due to its construal as being synonymous with fluffy, pomo, intellectual onanism. This is wrong. I’ll try to explain.

Frankly (and I’m fairly sure I speak for a large number of my colleagues) I have no interest in philosophy of science–NOW, after 16 years of benchwork.

This is a strange group for you to sign-up for. ;)

I’d love to see a demonstration of a real life example of a scientific study which would have profited from professional insight from philosophers.

When I have time, I’ll chose a specific example I am most familiar with, but for the time being:

Scientific disciplines founded by or having major contributions from philosophers: logic (Aristotle, Frege, Russell and countless others), economics (Adam Smith, Hume), psychology (William James), computer science (Godel, Church, logician precursors), probability theory, welfare economics (Rawls, Nozick), sociology (Auguste Comte, Marx), physics (Mach, Reichenbach)…

Methodological and conceptual contributions: inductive methods (Bacon, Mill), bayesian inference methods (Carnap), bayesian statistics (Ramsey, Seidenfeld), causal discovery (Spirites, Glymour), belief revision (Levi), object language/metalanguage distinction (Carnap), the role of simplicity in inference (Aristotle, Ockham)…

Problems faced by scientific inquiry and identified by philosophers: the problem of induction (Hume), underdetermination of theory by evidence (Quine), Dutch book problem (Ramsey)…

Specific software for discovery: *edit* MYCIN (created by a student of Hempel’s), TETRAD…

The history of science is to a large degree intermingled with philosophy. See History of Tweentieth Century Philosophy of Science for more details.

Now, you might be tempted to make an ad hoc move to say that when it was helpful, it was science (or math/logic), and when not, it is philosophy, but that is a philosopher’s (re)definition game. ;)

No offence taken, by the way.

LolaWalser couldn’t resist further rudeness:

I had anticipated this sort of reaction from a scientist.

Glad I didn’t disappoint!

Generally, there is a great deal of contempt for philosophy,

There is? You shock me. Yes, I’m well aware of the travails of postmodernism and its spats with science, but, first, we don’t all need to be lectured on what philosophy is (or was) beyond this category or cajoled into “tolerating” it. I love classical philosophy and if I were talking to an ancient Greek I’d very proudly describe myself as a philosopher to hiim. (I still sometimes talk of science as “practical philosophy” but only to people who don’t need my background and idiosyncrasies explained.)

This is a strange group for you to sign-up for. ;)

Actually, I didn’t sign up for it, nor do I intend to. Unless you wish to pay me to jeer from the sidelines… :) No, sorry, as I said I personally have no interest in PoS, but I will be checking occasionally to see what sort of crowd you draw.

When I have time, I’ll chose a specific example I am most familiar with, but for the time being:

Really, a specific example of a scientific study which would profit from professional philosopher’s insight is all I need. I certainly DON’T need this appallingly condescending rundown of history of philosophy and science. Are you SERIOUS?! I’ve been to school, sir–probably for much longer than you. I’ve even read a few books on the subjects!

Look, I’ll try to keep my good humour (I started replying to your post as I was reading it, never expecting this ridiculous “History of philosophy for dummies” capsule) and assume you’re simply naive, or have never in your whole life talked to a scientist. How in the world do you expect me to have graduated HIGH SCHOOL without philosophy? History? Logic? Mathematics?

Piece of advice: never underestimate the general education of a stranger. Is it because Americans seem to have lower expectations when it comes to schooling?

Now, you might be tempted to make an ad hoc move to say that when it was helpful, it was science (or math/logic), and when not, it is philosophy, but that is a philosophers (re)definition game. ;)

Is it now? Told you I’m a philosopher!

It is quite clear philosophers are feeling a bit rudderless these days, toppling from all-encompassing “love of wisdom” to… indeed, I’m not sure what.

Trying to maintain the peace, I ignored LolaWalser’s tone and tried to address her concerns:

Wow. I didn’t expect such a relatively rarified subject to recieve so much immediate attention– I am pleasantly suprised. I should clarify my modest claims.

PoS, in order to be a more fruitful discipline, should pay attention to implementation-level concerns in science and try to meet what I call Hausman’s challenge (“Philosophers of science have learned a great deal about science, but the knowledge falls short of any usable algorithm for scientific practice or theory choice,” Daniel M. Hausman, The Philosophy of Economics: An Anthology, Introduction): PoS should aim for providing such usable methods, though they have thusfar not (largely) met this goal. PoSt is well situated to do this because of its theoretical, interdisciplinary nature and emphasis on logical and mathematical tools. Also, philosophy has always been the incubator of sciences

I do not claim that PoS is, or should be, the sole authority in things methodological, nor that it always meets this goal. Some work by philosophers of science is junk (maybe even a majority of it), but this does not mean that philosophers have nothing to contribute.

My infodump in #5 was meant to illustrate the many contributions of philosophers to science, many of which can be used to refute the claim that philosophers do not, or cannot, advance science, as I understood LolaWalser to be making.

LolaWalser:

[Quoting a response I made to another discussant] Biochems have more rigorous standards than some disciplines, particularly those out of the research field, and in the applied sciences. My point is that methods should be backed by sound theory.

More rigorous standards of what?

Next, is your contention that biochemistry and applied sciences have laboured all this time employing methods without the backing of “sound theory”? If it is, can you show it is true?

Now, assuming that it is true (to speed things up–I personally think it’s a ridiculous statement–Not Even Wrong), what does it tell you, if the achievements of science so far have been produced “without” the backing of sound theory–such as you envisage?

And thank you for this quote, it provides a fitting conclusion:

“Philosophers of science have learned a great deal about science, but the knowledge falls short of any usable algorithm for scientific practice or theory choice,”

Yeesh. Again, trying to clarify:

Biochems have more rigorous standards than some disciplines, particularly those out of the research field, and in the applied sciences. My point is that methods should be backed by sound theory.

More rigorous standards of what?

More rigorous standards of experimentation, modeling and methodology in general.

Next, is your contention that biochemistry and applied sciences have labored all this time employing methods without the backing of “sound theory”? If it is, can you show it is true?

Now, assuming that it is true (to speed things up–I personally think it’s a ridiculous statement–Not Even Wrong), what does it tell you, if the achievements of science so far have been produced “without” the backing of sound theory–such as you envisage?

To quote a scientist, “There is nothing more practical than a good theory.” We are able to do quite a lot without theory in many areas of human endeavor. However, theory may allows us to systematize, optimize, predict and control where we could not do so before. I could imagine breeders making the same argument before Mendelian genetics.

What makes you think that science as currently practiced is optimal? How would you suggest our methods be improved, if not by reasoning about and a theory of its methods? This is just PoS. Can you give me a specific example of PoS and how it is as useless as you claim?

Philosophers of science are concerned with the understanding the nature, methods, theoretical products and success of the sciences. PoS uses the traditional methods of philosophy (conceptual analysis, explication) to this end, but also mathematical, logical and naturalistic methods are used as well. If you wish to call people who pursue such questions methodologists or gavagai, I don’t care– I’m just interested in the questions. Basically, science involves the use of hypothesis formation, modeling, experimentation, and test in an effort to discover, explain, predict and control natural phenomena. PoS and science are primarily distinguished by the level of abstraction and can benefit from each other (see Machine Learning and the Philosophy of Science (PDF) by Jon Williamson for an excellent overview of a mutually beneficial interaction between the disciplines).

I sometimes wonder why I bother with these exchanges.

Logicians Liberation League

Bob “The Maximum Leader” Meyer‘s manifesto of the “Logicians Liberation League”, recently quoted by Branden Fitelson in the context of promoting formal epistemology:

Do not be deceived, Establishment pigs (this means you too, Establishment dogs). The subservience of past generations of logicians does not mean that we shall bear forever our treatment as animals (you barnyard fowl). We are human beings (you swine). You are living in a day when logicians will not any longer endure your taunts, your slurs, your insults (you filthy vermin). In the name of A. N. Whitehead and B. Russell we gather; in the spirit of R. Carnap and A. Tarski, we march; by the word of W. V. O. Quine, we shall prevail. Beware you snakes of the Philosophical Power Structure, which you have created and which you maintain to put down the logician; you have caged the eagle of reason, the dove of wisdom, and the lark of a definite, precisely formulated formal system, with exact formation rules, a recursive set of axioms, and clear and cogent rules of inference, and you have made them your pigeons. Oh, you filterable viruses, we will shake you off and fly once more.

Viva la revolucion! You can read it in its entirety, here.

Art and Android Epistemology

While researching a bit on android epistemology for a wikipedia post, I came upon a reference to The Intelligent Design of Jenny Chow” (NYT Review):

Jennifer Marcus, an agoraphobic 22-year-old genius with obsessive-compulsive disorder who was raised in Southern California but born in China. Since she can’t bring herself to step outside her door, let alone work through the bureaucratic red tape of an adoption agency, she decides to build a robot out of obsolete missiles, name it “Jenny Chow,” and send it on a journey to find her mother.

Interestingly, the playwright of Rolin Jones happened upon the seminal book in AE (aptly names Android Epistemology) while doing research for his play and found inspiration in it:

He dusted off an eclectic tome called Android Epistemology, which had never been taken out by a student. “The pages were still stuck together,” he recalls. “I was amazed that somebody had written 250 pages on the theoretical epistemology of thinking, breathing robots.”

I’ll have to forward this reference to Clark, he would probably find it amusing.

It’s a pity that the book languished on some shelf, instead of being read by students of philosophy, and machine learning; I believe that this more applications-oriented approach to epistemology is the future of the subject, rather than the scholasticism of traditional epistemology.

Anyway, here is the text of my entry on android epistemology:

Android Epistemology
From Wikipedia, the free encyclopedia
Jump to: navigation, search

Android epistemology is an approach to epistemology considering the space of possible machines and their capacities for knowledge, beliefs, attitudes, desires and for action in accord with their mental states. Thus, android epistemology incorporates artificial intelligence, computational cognitive psychology, computability theory and other related disciplines.

Philosophy in Runtime

In the past few months I have been challenged to defend computational philosophy, particularly philosophical modeling. Philosophical modeling, like scientific modeling, is a formalization process. However, instead of capturing real-world phenomena, philosophical modeling captures thought experiments.

The process of encoding a thought experiment in a formal system is, itself, beneficial in the same way as standard conceptual analysis: hidden assumptions are unburied and seemingly simple ideas yield refined notions. But, in a way, encoding is more honest–the process is not satisfied until you reach a syntactic, algorithmic level of explicitness and, once our intuitions are encoded, further light may be cast during runtime. Will your thought experiment crash, loop endlessly, or churn away at intractable problems? Do your assumptions actually lead to your conclusions? Do they yield more than expected? Less? As any programmer knows, what we program to happen and what actually happens can be quite different.

Philosophers often use formal systems to reinforce their arguments, but they are typically piecemeal and the most significant assumptions (often unintentionally) remain outside the formalism. Computers are well suited to explore certain features of complex systems like thought experiments. With a computer, philosophers may encode their thought experiments and systematically explore their features. This cannot be matched by armchair speculations. We are prone to errors in inference and unconscious biases, and simply do not have the time or energy to consider the complex interactions of philosophical presuppositions.

I should note that this methodology is not completely foreign to philosophers. Here are a few examples:

  • Daniel Dennett uses cellular automata as a toy world to test our thoughts about evolution, model making, and free will (Darwin’s Dangerous Idea, ‘Real Patterns’ in Brainchildren, Freedom Evolves).
  • Grim, Marr and St. Dennis programmed logical and game theoretic systems to illuminate standard philosophical problems in The Philosophical Computer.
  • Lastly, in John Pollock’s essay ‘Procedural Epistemology’ (in The Digital Phoenix) he reports about OSCAR, an epistemological agent, to demonstrate his philosophical theories.

In the last essay we are encouraged to "put our model where our mouth is" when it comes to our epistemological theories. Indeed we should, in epistemology and elsewhere.
