Darwin-L Message Log 9: 211–233 — May 1994
Academic Discussion on the History and Theory of the Historical Sciences
Darwin-L was an international discussion group on the history and theory of the historical sciences, active from 1993–1997. Darwin-L was established to promote the reintegration of a range of fields all of which are concerned with reconstructing the past from evidence in the present, and to encourage communication among scholars, scientists, and researchers in these fields. The group had more than 600 members from 35 countries, and produced a consistently high level of discussion over its several years of operation. Darwin-L was not restricted to evolutionary biology nor to the work of Charles Darwin, but instead addressed the entire range of historical sciences from an explicitly comparative perspective, including evolutionary biology, historical linguistics, textual transmission and stemmatics, historical geology, systematics and phylogeny, archeology, paleontology, cosmology, historical geography, historical anthropology, and related “palaetiological” fields.

My favourite quotation, presented to students to warn against equating social and natural sciences: "We can predict that in the world of 1985 we shall have psychological theories that are as successful as the theories we have in chemistry and biology today." This was uttered 30 years ago by one of the great American geniuses of the 20th century, Herbert A. Simon, in "The Corporation: Will it be Managed by Machines?" repr. in Morris Philipson (ed.) _Automation: Implications for the Future_ (Random House-Vintage, 1962, p. 259.) The character of this prediction says more about current thought in the 1960s than the fact that it turned out wrong. I come to this theme from an undergraduate major in philosophy in the 1960s and specialization since the 1970s in science studies. A fundamental paradox is that practising philosophers read current science but practising scientists do not read current philosophy, with one rare and notable (Karl Popper.) The philosophy of science is now a mature discipline (Plato to Bacon to Whewell to living investigators like Bourdieu and the sociologists). But scientists interested in theory have found it more convenient to improvise whatever philosophy they need on a do-it-yourself basis, sometimes naively, than to borrow it from disciplinarized philosophy in the way they would borrow facts or theories from natural science disciplines outside their own fields. My own working hypothesis is that this reflects a structural difference between classes of disciplines: that the natural sciences strongly converge on single dominant paradigms and protocols, whereas the social sciences as well as the humanities tolerate diverse and even contradictory paradigms. Departments of psychology, economics, history, etc. contain individuals who believe each others' principles and methods are totally wrong, but for practical purposes coexist more or less peacefully. They know their paradigms conflict but keep quiet about it for the sake of material benefits (status of the discipline etc.) By contrast, rival paradigms in natural sciences from astrophysics to zoology rapidly generate research programmes to select between them, i.e. discover and converge on the one truth. So it should not be surprising that discussion in this list of taxonomy has not yet cited the oldest continuous literature on the subject. In disciplinarized philosophy this is the question of "universals:" whether such ideas as "virtue," "chair" or "arithmetic" belong to an independent universe of real Platonic forms, replicated in our experienced world with more or less accuracy, or are invented (Aristotelian) generalizations about the experienced world, with an asymptotic (i.e. progressive) relationship to perfect truth. -- | Donald Phillipson, 4180 Boundary Rd., Carlsbad | | Springs, Ont., Canada K0A 1K0; tel: (613) 822-0734 | | "What I've always liked about science is its independence from | | authority"--Ontario Science Centre (name on file) 10 July 1981 | _______________________________________________________________________________ <9:212>From ahouse@hydra.rose.brandeis.edu Sat May 28 11:36:24 1994 Date: Sat, 28 May 1994 12:38:34 -0400 To: darwin-l@ukanaix.cc.ukans.edu From: ahouse@hydra.rose.brandeis.edu (Jeremy Creighton Ahouse) Subject: no "right" answer for classifications? A few days ago Bonnie Blackwell wrote (as part of a response on Teaching phylogenies): >This leads me to believe that there is no "right" answer for classifications >merely one that is currently most acceptable given our current knowledge. In this area, classifying our planet's living forms, it seems to me that there _is_ a right answer. The arguments between methods are how to best uncover this answer (this somewhat tangled, often bifurcating, web of answers). Even non-cladists seem to share the belief in a single (possibly unknowable, certainly not, currently, fully known) branching pattern. Reticulation, noise, and the departure of history from minimum character state transitions make the job difficult for the phylogenetic taxonomist, but(!) none of this suggests that the ontological status of the "answer" is in trouble. So I am with David Baum: >By >starting from classification and moving to phylogeny there is a tendency to >view the classification AS the phylogeny rather than as an approximation >thereof. With the caveat that there are discussions of "regularities" in nature that give rise to the "belief" in the essential qualities of the taxonomic hierarchy (e.g. families as entities; as in angiosperm families defined primarily by flower structure*). It seems important to include an experience of this in teaching phylogenies as well. - Jeremy * Do any of you have a good reference to a good review of "reasons" for the priveleging of flower parts in (defining) plant families or dentition in mammals, or...? My feeling is that this becomes incresingly problematic. Recently structural biologists (after caving in on the possibility of calculating tertiary structure from the chain of amino acids) have begun to suggest that there is a taxonomy of higher level structures coiled coils, leucine zippers, etc... out of which they will be able to "predict" structures. I am uneasy about the status of this classification. Is this more than the wonderful human ability to classify? With some preference for ~7 categories per level? ____________________________________________________________________ Jeremy Creighton Ahouse (ahouse@hydra.rose.brandeis.edu) Biology Dept.

David Baum and Vince Sarich were trying to make this distinction, and I'd like to reinforce their positions. One of the most important advances in systematics in the last 25 years has been the explicit recognition that there are two different intellectual activities that are often conflated, namely phylogenetic reconstruction and classification. Confusion often arises (and has arisen here a little) because terms like "classification", "taxonomy" and "systematics" are sometimes used to refer to only classification, or only to phylogenetic reconstruction, or to both, or to both without a clear distinction made between the two. Phylogenetic reconstruction is an historical task. There was some true sequence of events that took place in the evolutionary past -- the past only happened one way. That sequence of evolutionary events ("the evolutionary chronicle") is phylogeny, and phylogenetic reconstruction is an historical enterprise: its purpose is to reconstruct or estimate that true sequence of events as well as possible. Any particular phylogenetic estimate (an evolutionary tree) may be a good or bad estimate of the true sequence of historical events, but that's still what it is: an estimate of some actual sequence of events. The object of classification, by contrast, is to group things. Things can be classified -- grouped -- whether they are genealogically connected or not. I can classify library books by the color of their binding, trees by their height, postage stamps by the number of perforations they have, and on an on. The product of classification -- a classification -- isn't an historical inference, it's a grouping. While it might make perfect sense to speak of classifying pieces of furniture, or library books, it doesn't make any sense to speak of estimating the phylogeny of furniture or library books, because pieces of furniture and books in a library aren't genealogically connected in ancestor-descendant relationships as organisms are. (In the case of books, an important exception is of course the transmission of a particular text through many copies. This is the field of stemmatics or textual transmission, and a stemma is indeed a textual phylogeny: an historical inference. But stemmatics is not what you learn in library school in a course on book classification.) A selection of contemporary works in systematics that discuss the basis for the distinction between classification and phylogenetic inference would include the following (among others): Ax, P. 1987. _The Phylogenetic System_. New York: John Wiley & Sons. de Queiroz, K. 1988. Systematics and the Darwinian revolution. _Philosophy of Science_, 55:238-259. Griffiths, G. C. D. 1974. On the foundations of biological systematics. _Acta Biotheoretica_, 23:85-131. O'Hara, R. J. 1993. Systematic generalization, historical fate, and the species problem. _Systematic Biology_, 42:231-246. Back in the very early days of Darwin-L the issue of phylogeny versus classification came up also, and at the time I posted a fairly long account of my own view of the situation; I append an edited version of it here for anyone who wasn't around at the time and who may be interested. --begin included message--------------- <1:173>From DARWIN@iris.uncg.edu Sat Sep 18 16:50:25 1993 Much discussion of "classification" in fact fails to make a very important distinction now made within evolutionary biology between two different activities: (1) classifying (making groups), and (2) reconstructing phylogeny (evolutionary history). Until this distinction is clearly made there really can't be any fruitful discussion of either classification or phylogeny. This whole subject has been _enormously_ clarified in the last 25 years or so, and all practicioners in the field now make this distinction clearly. Here's a sketch of my reading of the situation; I'm sure my views are not universally held in all their details, but neither are they unique. Every paragraph below could easily be given monographic treatment, and many have been; my aim here is just to give a broad sketch for those who have an interest in the subject but have not followed the literature closely. We have among our members some leading historians of systematics and some leading systematists, so I apologize if I do violence to any of their views in the interest of brevity. While my comments address evolutionary biology, I like to think they have implications for historical linguistics and stemmatics as well. The last 25 years has seen an enormous growth in the study of phylogeny, the evolutionary history of life. This was one of the great fields of study in the late 1800s, but for much of the early and mid-20th century phylogeny was comparatively negleced in favor of studies of evolutionary mechanisms and "species-level" problems. (This species-level work was enormously important of course, and it is still with us.) Since the mid 1960s, however, interest in phylogeny has grown enormously due to three factors: (1) the development of computational methods for dealing with large quantities of data; (2) the availability of data on comparative molecular anatomy, though this has not been as important to the conceptual development of the phylogenetics revolution as the popular press (and some molecular biologists) would have people believe; and most importantly (3) a new conceptual understanding of the relationship between the observed similarities and differences among organisms and the histories that can be inferred from those similarities and differences. This last factor is behind the method of "cladistic analysis" which has effected a revolution in the study of phylogeny, and which is now the standard method for reconstructing evolutionary history. The conceptual development of cladistic analysis in the last 30 years or so has been as important to systematics as the development of the law of superposition -- that upper strata are younger than lower ones -- was long ago to geology. The briefest sketch of the long view of this subject would go like this (many of these statements could be qualified; there is an increasing body of published literature on this). Beginning in the 1600s and 1700s there was an enormous increase in factual knowledge of natural diversity on the part of European scientists. The notion of a linear "chain of being" which had been the principal organizing system for diversity up until that time came, as a consequence, to be challenged in the late 1700s and early 1800s, and a variety of other arrangements were conceived for the diversity of life, including maps, stars, circles, nets, and trees. Notice that I spoke here of _arrangements_. It is entirely true that many students of diversity were engaged in classification and published classifications. But many theorists even during this early period argued that "classification" was not the right intellectual model for understanding and representing the structure of living diversity. In simplest terms, classifications are based on group-within-group relations; _arrangements_ may be based on group-within-group relations but also on some sort of positional relations in an abstract space: taxa are not only contained within other taxa, they are also near and far, between, above or below other taxa. Think of the difference between a printed listing of states, counties, and cities (group-within-group), and contrast that with a map of those same places showing their positions in geographical space. The chain of being is an example of a linear _arrangement_; it is not strictly speaking a classification because it contains a linear axis along which taxa must be placed. The term "system" was often used as a synonym of "arrangement", and people came to speak of "the natural system" -- that is, the true arrangement of the diversity of life. From this notion of system we derive the term "systematics" which is used for the field today. Many important workers in the early 1800s directly contrasted classifications (which they regard as inferior) with systems/arrangements, among them Macleay and Alfred Russel Wallace. One sometimes hears people say "a natural system of classification", but to the workers in the past or the present who make the distinction between classifications and systems/ arrangements, a natural system of classification is an oxymoron: the reason such people speak of natural systems is because nature isn't arranged in classes. A very special conflict arose once people accepted the notion of evolution and it became clear that the true arrangement of living diversity (the natural system) is a tree. This conflict arose because there are two kinds of tree diagrams: (1) "logical trees" representing classificatory relations, and (2) historical, genealogical trees: "trees of history". I can make a "logical tree" showing the classification of furniture into chairs and tables, and then into desk chairs, dining chairs, lounge chairs, etc. Such a "tree" however is purely a classificatory device that has nothing whatever to do with evolutionary, genealogical, "trees of history", in which the root is an actual organism or population that lived in the past. One of the most troublesome problems in the history of systematics has been the confusion of logical trees and trees of history, that is, classifications and phylogenies. It is an empirical fact that people within and without the field of systematics have found "group thinking" to be easy and intuitive, but "tree thinking" (historical/genealogical tree thinking) to be extremely difficult. It is possible to see the seeds of this confusion in the classification chapter (XIII) in the first edition of the _Origin of Species_ where Darwin distinguishes precisely between classification and arrangement in several places (and here he owes much to an earlier paper by Wallace, I believe) but doesn't really develop all the consequences that result from this distinction, especially in view of the fact that many traditional groups were clearly not whole branches of the evolutionary tree (the logical and genealogical trees did not match). Because the full implications of the classification/phylogeny distinction were not genuinely internalized in systematics until quite recently, some people have spoken of the Darwinian revolution in systematics -- the idea that systematics is really about reconstructing evolutionary history, and that the natural system is in fact the sequence of events (the "chronicle") that make up the evolutionary past -- as being effected only within the last 20 years or so. Now, is classification as a particular kind of intellectual activity a valuable thing to study from the point of view of the history of systematics? Absolutely it is, in precisely the same way that phlogiston theory is important to study in the history of chemistry, and astrology is important to the history of astronomy. And it is certain that there are elements of "group thinking" still present in systematics today that need to be eliminated; study of classification will help us to understand why these persist and how people regard them. But theoretical considerations of "classification" as a distinct intellectual practice are not relevant to the contemporary _practice_ of systematics, which has as its task the reconstruction of evolutionary history. There is nothing that sounds more utterly barren today than the debates of the 1970s over "my way of classifying is better than your way of classifying." --end included message----------------- Bob O'Hara, Darwin-L list owner Robert J.

The philosophy of >science is now a mature discipline (Plato to Bacon to Whewell to living >investigators like Bourdieu and the sociologists).

I offer in return an equally chiding but very cordially-intended response: First of all, it would seem to me that both philosophy and science, as things produced by communities of people in particular historical contexts, partake equally of do-it-yourself improvisation, and that there have been at least one or two philosophers in the history of that field whose work might be labeled scientifically "naive", just as there have been scientists to whom the label "philosophically naive" might be applied. Donald gives as a possible example of scientists' inattention to the philosophical literature the absence of any reference to essentialism in our recent discussions here on teaching "taxonomy": >So it should not be surprising that discussion in this list of taxonomy >has not yet cited the oldest continuous literature on the subject. In >disciplinarized philosophy this is the question of "universals:" whether >such ideas as "virtue," "chair" or "arithmetic" belong to an independent >universe of real Platonic forms, replicated in our experienced world with >more or less accuracy, or are invented (Aristotelian) generalizations >about the experienced world, with an asymptotic (i.e. progressive) >relationship to perfect truth. My reply to this will distinguish pedagogy from current research. With respect to pedagogy, I think Donald would find that many if not most introductory courses in evolutionary biology include some treatment of essentialism (which is what he is asking about), particularly with respect to the notion of species, and an explanation of how evolutionary biology replaced essentialism by what we call population thinking -- one of the core ways of seeing the world that is built into evolutionary biology. In my freshman seminar on Darwin, for example, we read about Plato's cave and assorted other essentialist views, and contrast them with a populational view of species under which there are no essences/types. As another example, if you look in the appealing book _Darwin for Beginners_ by Jonathan Miller and Borin Van Loon (New York, 1982), you will also find a pedagogical treatment of essentialism. Now are these presentations (mine included) highly sophisticated interpretations? Certainly not; they are simplified practical expositions for beginning students. A more thorough and sophisiticated treatment of the history of essentialism in systematics would indeed be very interesting, and I understand Darwin-L member Gordon McOuat in Cambridge is working in this area; I am looking forward to reading what he writes. But essentialism certainly is discussed in a simplified pedagogical form very widely by evolutionary biologists. Now with respect to contemporary research and the teaching of contemporary ideas (rather than the historical background of the field), essentialism and Platonic universals are not much discussed, quite simply because they are false and play no part in contemporary systematic practice. When one views the object of systematics not as a classificatory one, but rather as an historical one -- namely the reconstruction of evolutioanry history, as I argued in a recent message -- then it becomes even more clear why essentialism is irrelevant. At the same time, however, there is a very substantial literature on essentialism and species-as-universals versus species-as-particulars in the "meta-systematic" literature (contrary to Donald's implications). In general terms, though, it has been the systematists who have had to "correct" the philosophers, the latter having traditionally (though not much any more, and certainly not on Darwin-L! ;-) failed to understand that species aren't universals and don't have essences. A very tiny sample of this vast literature would include: Ghiselin, M. T. 1974. A radical solution to the species problem. _Systematic Zoology_, 23:536-544. Ghiselin, M. T. 1987. Species concepts, individuality, and objectivity. _Biology and Philosophy_, 2:127-143. Hull, D. L. 1978. A matter of individuality. _Philosophy of Science_, 45:174-191. Mayr, E. (Various works on population thinking versus essentialism; I don't have the references at hand.) (Mayr has had an explicit anti-essentialist/anti-Platonic theme in almost all his writings for 50 years, and Ghiselin has similarly argued against species-as-universals in a great many papers.) But here's what surprises me in this general context (continuing in collegial chiding mode): As someone who has spent a bit of time among philosophers (many of whom I count as good friends and colleagues), I have observed that there are few sub-disciplines within philosophy that are more marginalized than philosophy of history. In comparison to the amount of attention that is given to philosophy of science, or ethics, or aesthetics, or any of a number of other fields, the attention given to the philosophical basis of history, historical inference, and historical representation is very slight. Why might that be? If evolutionary biology is an historical science, and if at least some of its intellectual affinities lie with history, historical linguistics, stemmatics, stratigraphy, etymology, archeology, historical geography, and so on, then why don't we hear more people talking about the work of William Dray, or Louis Mink, or Robin Collingwood, or Arthur Danto, or Morton White? (All of them 20th-century philosopers of history.) Why is there so little philosophy of historical linguistics (there is lots of philosophy of language, but that's completely unrelated) and so little philosophy of geology? These are of course very complex questions, and every field, including philosophy, has a lot of historical inertia that keeps it moving toward certain classes of problems and away from others. One of my hopes in creating Darwin-L was that a forum of this kind might help to reduce such disciplinary inertia, and enable people to explore some intellectual relations that they may not have been particularly conscious of before. Thanks to questions like Donald's and the participation of everyone here we seem to be doing an excellent job of that very thing. Bob O'Hara, Darwin-L list owner Robert J.

(The Essay appears at the head of Agassiz's Contribution to the Natural HIstory of the United States). That the essay is significant is evident, albeit obliquely, by the reference in E. Lurie's biography of Agassiz that he was preparing for Harvard U.P. an edition of the Essay, presumably for appearance in the early sixties. Query: did this essay ever appear under Lurie's editorship. If not, why not? The Essay is certainly a fascinating piece of work and well worth the study.

Winsor] I show: that he wrote it between January of 1854 and July of 1856 (the references to the Origin of Species were added later) that his view that there are multiple parallels (affinity, embryology, fossils, geography) and that they contain profound meaning was typical of his day that the idea that evolution could explain those parallels threatened him because it implied a lack of superintending divinity that an original idea he proposed in the essay was that not just the category "species" but the whole nested set of categories (genus, family, order, class, embranchement) were pure intellect, the categories of God's thoughts I argue that this idea evolved in the context of his teaching, and his famous case study method of teaching (one dead fish for a week) was designed to impress it on his students that other biologists failed to find this idea useful that it is deeply wrong - a pushing of essentialism to such an extreme that its wrongness becomes obvious Some of you may also be interested in my article "Louis Agassiz and the species question" Studies in History of Biology, 1979, 3:89-117.

There is a short entry for him by Melville H. Hatch in the _Dictionary of Scientific Biography_ (1975). He was a student at Williams College in Massachusetts, and then did advanced work with Agassiz at Harvard from 1857-1864. He specialized in the systematics of Orthoptera (grasshoppers, et al.) and fossil beetles, apparently, and had a rather tragic personal life. The DSB suggests the following sources: On Scudder and his work, see J. S. Kingsley, William L. W. Field, T. D. A. Cockerell, and Albert P. Morse, "Appraisals of Scudder as as a Naturalist," in _Psyche_, 18(1911), 174-192, with portrait; and Alfred Goldsborough Mayor, "Samuel Hubbard Scudder 1837-1911," in _Biographical Memoirs, National Academy of Sciences_, 17(1919), 79- 104, with portrait and bibliography of 791 titles.

While literally true, I think this remark rather complacent. Philosophers of science -- by and large -- take it as part of their task to inform themselves of one or more sciences in a detailed way, so that they do not end up with a philosophy primarily consisting of ignorant puffings of an armchair experimentalist. When scientists wax philosophical, the story is largely different. Perhaps the thinking is that philosophy is largely just refined common sense, and they've got as much common sense as anyone. The result, however, is quite commonly putrid philosophy. I would take issue with just about everything else the original communicant said, however. Popper is not exactly a contemporary philosopher of science -- his main contribution dating from 1934 -- even if he is still alive. Scientists have also caught up with Kuhn, whose main work in philosophy of science was written ca. 1960. And I take exception to citing *sociologists* as representative of contemporary philosophy of science.

It consisted of letters on the question of whether a theist could be a good scientist. He remarked on the fact that most of the correspondents, holders of the degree of doctor of philosophy, were advancing arguments that would be greeted with derision in his second-year undergraduate tutorial group in philosophy! Scientists know that science is conceptually challenging, but often assume that the humanities and the social sciences make no comparable intellectual demands. This leads those so minded to believe that they can pontificate with impunity in areas they have made little effort to comprehend. He is also right to point out that many working scientists have moved beyond Popper; I was part of a group that worked through Kuhn's book with atom-torturing scientists at this institution more than fifteen years ago!

Hineline) Subject: Re: Essentialism, philosophers, and scientists To: darwin-l@ukanaix.cc.ukans.edu Date: Tue, 31 May 1994 06:57:30 +119304128 (EDT) Donald Phillipson is to be commended for raising the question of the relation of philosophy to the practice of science and for beginning a healthy debate on the matter, substantively aided by Bob O`Hara's gently "chiding" rejoinder. Bob's comments on the marginality of the philosophy of history were quite temperate; one has only to look at mainstream philosophy of science to note the marginal place of historical explanation (e.g.: the notion of the "explanation sketch" in the logical empiricist tradition). Although Kevin Korb is sympathetic to much of the discussion, he takes "exception to citing *sociologists* as representative of contemporary philosophy of science." But he gives no reasons for taking exception. Perhaps his reasons are related to disciplinary boundaries, perhaps not. But sociological question, particularly those arising out of the sociology of scientific knowledge (SSK) offer hope of a more rigorous philosophy of historical explanation in science, even if that promise has yet to be fulfilled. This is especially true when certain tenets of SSK are used in the history of science to understand historical sciences. One example of an open question that transcends these disciplinary boundaries is the nature of scientific "problems." The term "problem" can be used to designate any sort of question in or about science. But careful attention to primary sources suggests that certain questions, designated "problems," are especially perplexing. Often, the designation signals the intersection of several disciplines or subdisciplines in the sciences, and difficulties in agreeing on methods, kinds of evidence, and strategies of argument. "The species problem" has been recently discussed on this list; other examples are the "coral reef problem," and the "granite problem." When these and similar examples of "problems" in science are examined through case studies, I suggest that the difficulties of integrating causal and historical explanation will become somewhat more apparent, if no less perplexing. Once dis- entangled by the joint efforts of scientists, historians, philosophers, and sociologists of science, a philosophy of science may begin to emerge that is applicable to the practice of historical explanation in science. In the meantime, scientists can hardly be faulted for applying "common sense" as a default philosophy of science. Mark L.

Nyhart <LKNYHART@macc.wisc.edu> Subject: Re: Essentialism, philosophers, and scientists To: darwin-l@ukanaix.cc.ukans.edu I was interested to read Mark Hineline's discussion of the nature of scientific "problems" as especially perplexing questions, often at the intersection of several disciplines or subdisciplines. It reminded me of a slightly different take on the "history of questions" in science developed by Nicholas Jardine. In his essay "The significance of Schelling's 'Epoch of a wholly new natural history': an essay on the realization of questions" (in R.S. Woolhouse, ed., _Metaphysics and Philosophy of Science in the Seventeenth and Eighteenth Centuries_; Kluwer 1988, pp. 327-350), Jardine proposes that we reconsider the history of science as the history of the "validation and invalidation of questions." One reason that Oken and Schelling seem so strange to us, Jardine suggests, is that they addressed "what are for the most part, from our standpoint, _unreal_ questions" (338). Jardine suggests that to understand how questions become viewed as valid or invalid, we need to look both at natural historians' methodological and epistemological commitments, on the one hand, and their day to day practices, and see how they inform one another. What does this have to do with Hineline's discussion of scientific "problems"? I wonder whether those areas viewed as "problems" might be especially valuable nexes for investigating the validation and invalidation of questions. Within a big, intractable problem like "the species problem," can we trace certain questions and approaches that became invalidated, and others that became validated (perhaps NOT directly in relation to Darwinian evolution--or is it impossible to disentangle anything about "the species problem" from Darwinism?)? Food for thought, anyway.

Philosophers probably think he is an historian, and historians like me may think of him as a philosopher. But the idea Nyhart cites is repeated and developed further in his book The Scences of Inquiry: On the reality of questions in the sciences, Oxford (Clarendon Press) 1991 It has a chapter on "legitimation and history" discussing the way scientists use the history of science to establish or strenghten theories or disciplinary divisions. But if that implies we must beware of believing what scientists tell us about their own past, the burden on us very few professional historians of science becomes heavy indeed, since at the end of the book Jardine tells philosophers and scientists that they have to pay more attention to the history of science. Which is why I am reading Peter Novick That Noble Dream:the ideal of objectivity in the American Historical profession and formulating a plan to look at how systematists have in fact constructed and used history. Maybe it isn't all merely legitimating, maybe some of it is enlightening? People on this list seem to feel history can be uncovered and is worth knowing...

In our own Artificial Life group at UCLA the subject of emergence has come up numerous times, and although David Tinker was not present he has captured much of what was said. What we arrived at as a definition follows Luc Steels' formalization which goes something like this: "Given a system with a global behavior completely determined by the local behaviors of its components, a global behavior can be said to be EMERGENT if it requires a set of descriptors which is different from the set required to describe the local behaviors." Someone on Darwin-L asked rhetorically whether anyone in evolution still believed in Teleology. It would be interesting to rephrase that question to ask whether any phenomena explained as teleological in a non-computational paradigm could be subsumed under the the computational paradigm of emergence? I suspect so. I also have a nagging suspicion that emergence is central to biological evolution and possibly also to cultural evolution, if not the entire range of natural phenomena. I've breached the subject with Gould, Rapoport, and Mayer who have all commented that the field of Alife is "rich." To obviate any misunderstandings, in my view evolution is a change in gene (or trait) frequency in a population over time (I will not use the word "progress)." And cultural evolution can come about through both Darwinian and Lamarckian mechanisms {appeal to authority: Mayer}. I must admit I'm having difficulty keeping up with this thread on several bulleting boards, but even though the postings are sporadic, they are fruitful.

I. Introduction : Organization: University of Toronto, Biochemistry : Date: Wed, 11 Nov 1992 15:50:22 GMT : The recent spate of articles in talk.origins on "emergent properties" : generated some heat, but not much light! My colleague, Larry Moran, : objects to the term because he suspects (wrongly) that it is based on : non-mechanistic or vitalistic superstition, and (rightly) that the term : implies there is an obstacle to the reductionist agenda in biology. : Other postings imply that the term "emergent properties" is tautologous, : and not unique to biology; it has been claimed that everything has emergent : properties, so the adjective "emergent" is meaningless. : I think the topic is worth further exploration, and submit this article to : stimulate discussion. I hope that we have not seen the last word on this : topic. : First, I do not think there is a satisfactory closed definition of the term : "emergent", nor is it universally used by the research school most concerned : with such properties, the 'Artificial Life' community. Nevertheless I : believe the concept is so well accepted in this community that the term can : be used casually with the assurance that it is understood. I turned to my : well-thumbed copy of "Artifical Life I" and searched in the annotated : bibliography and in the index for terms like "emergent" - see below for the : results. Nowhere did I find a definition that would satisfy Larry Moran, but : in re-reading the articles I found many clues to a definition. So, being : willing to be called a fool, I will essay a definition: ============================================================================= : A system may be said to possess "emergent properties" when (a) it is composed : of a collection of entities, (b) it has global properties, obeying well- : characterised rules that may be used for predictive purposes, that arise from : non-linear combinations of local interactions among the entities, and (c) the : rules do not depend specifically on the chemical nature of the entities." ============================================================================= : Glosses: : By "entities" I mean systems which may exist independently, and which : make up the system by simple addition to it. Thus the protein molecules : in a crystal are entities in this sense, but the atoms in a molecule are : not "entities" composing the molecule. : By "non-linear" I simply mean the mathematical connotation, as in "non-linear : function". I wished to use this term in the definition rather than the : less general adjective "non-additive". : =========================================================================== : Now some questions and tentative answers. : 1. Do such systems exist? : : Yes they do. Three systems with emergent properties that have been : well examined are (a) artificial neural networks, (b) organisms that : exhibit schooling or flocking behaviour, and (c) cellular automata. : 2. You say that the properties are independent of chemical nature of the : entities. Does this mean you espouse a non-mechanistic view? : : Not at all. Let's take flocking behaviour as an example. It appears : to arise when entities have a mechanism for detecting spatial proximity : of identical entities and a feedback mechanism for maintaining a range : of postions relative to their neighbours. Essentially identical : behaviour can arise in organism as diverse as fish, insects and birds. : It could also arise in collections of robots made out of Lego (tm) - all : that is required is there be physical mechanisms for _instantiating_ : the local interactions. If I were studying sandpipers, say, I would : certainly hope to elucidate the physiological and biochemical mechanisms : of recognition and feedback, and to learn how the relevant genes have : evolved to optimise these interactions for efficient flocking behaviour. : The _instantiation_ of the behaviour does depend on mechanisms which : obey the laws of physics and chemistry, but the behaviour itself trans- : cends these laws. : 3. Aren't these rules merely empirical inventions that will be unnecessary : when we understand the mechanisms fully? : : I don't think so. The work in this area indicates many of the "rules" : governing such properties are universal, and have a formal logical : structure and grammar. In the sense that thermodynamics is a formal : system independent of any specific physical system, so are the laws : governing emergent properties. However, it is true that like : thermodynamics, "emergo-dynamics" will be ultimately related to : lower-level physical theories. : 4. Aren't all properties of matter "emergent" - e.g. the properties of : water? : : Not in the sense I have defined. The properties of water depend : absolutely on the specific interactions of water molecules, whereas : the properties I have called "emergent" would arise no matter what : entities are involved. : 5. Simple things like flocks and cellular automata don't convince me - : these are just computer games. Is there any evidence that *real* : biological behaviour can be 'explained' by such notions? : : I'm glad you asked. See the amazing chapter by P. Hogeweg (cited below) : in which he models such high-level behaviours as bumblebee sociology. : The fact that successful models of living systems can be constructed : out of computer instructions or Lego indicates that the properties being : modelled are 'real' ones. : 6. Wait a minute! I'm beginning to think you are a Moravecian (see Hans : Moravec, "Mind Children"). Do you really think biological properties : including (choke) consciousness could arise in machines? Is Data (in : Star Trek) really human after all? Do you think human beings are : machines? : : Yes. In fact, my conviction that my humanity has "emerged" from the : properties of molecules contributes mightily to that emergent property : of me, that I call a "religious world-view". : 7. How can I learn more about such area so that I can critically discuss : this topic on talk.origins? : : Start with the "Artificial Life" volumes from the Santa Fe insitute, : published by Addison Wesley. In my next posting, I'll re-post a : *long* annotated bibliography that was prepared by G. Miller and P. Todd, : and posted in sci.bio a year ago. : ----- : Bibliography and Footnotes: : ========================== : >From the annotated bibliography, in C.G.

It would certainly be nice to see an historical trajectory of the referents to the term and its auxilliary concepts, and its relation to discussions of teleology, reductionism, vitalism, etc. I can offer the following recent sources, but all refer to deterministic computational emergence, a referent which cannot be more than a few decades old. It would be enlightening to know in what ways computational emergence is congruent with pre-computational definitions of the term. An answer to that question would likely have to wait for the results of computational approaches to pre-computationally formulated problems in t he biological and social evolutionary sciences. Nevertheless, it does seem that we now have a computational method for dealing with some problems which were intractable when Kroeber was formulating his arguments on the "superorganic" in 1917. ========== CELLULAR AUTOMATA: Gutowitz, Howard, editor 1991.

Surely he can't mean (and you can't mean) the knowledge one acquires from living in a culture becomes incorporated in one's genome and thereby inherited by one's offspring. What can be meant be saying that Lamarckian mechanisms are involved in cultural evolution? ------------------------------------------------------------------ Gary A.

Date: Tue, 31 May 94 20:05:00 PDT Gary Cziko is of course correct. I apparently did not make my point clearly enough. I will try again... Biological evolution is often defined as a change in allele frequency in allele (gene) frequency in a population over time. I will make a parallel statement for culture, using biological evolution as a metaphor, by saying that cultural evolution may be defined as a change in trait (artifacts, fashions, ideas, styles, themes, etc.) frequency in a population over time. I do not mean to imply that cultural traits can be inherited as biological alleles. I do mean to imply, that applying the Lamarckian and Darwinian modes of evolution to culture can be a fruitful way of looking at cultural change. We could call this adapting a biological metaphor for the social sciences, or alternatively we could expand the concept of evolution to include non-biological (that is cultural) phenomena. Many anthropologists choose the latter. Among those who do, most argue that cultural evolution is entirely Lamarckian. I would say that it is both Lamarckian and Darwinian. Ernst Mayr made the same statement (for both) at a presentation to the Center for the Study of Evolution and the Origin of Life at UCLA a few months back.

Mark wrote: >One example of an open question that transcends these disciplinary >boundaries is the nature of scientific "problems." The term "problem" >can be used to designate any sort of question in or about science. But >careful attention to primary sources suggests that certain questions, >designated "problems," are especially perplexing. Often, the designation >signals the intersection of several disciplines or subdisciplines in the >sciences, and difficulties in agreeing on methods, kinds of evidence, and >strategies of argument. "The species problem" has been recently discussed >on this list; other examples are the "coral reef problem," and the >"granite problem." Lynn followed: >I was interested to read Mark Hineline's discussion of the nature of >scientific "problems" as especially perplexing questions, often at the >intersection of several disciplines or subdisciplines. It reminded me >of a slightly different take on the "history of questions" in science >developed by Nicholas Jardine. In his essay "The significance of >Schelling's 'Epoch of a wholly new natural history': an essay on the >realization of questions" (in R.S. Woolhouse, ed., _Metaphysics and >Philosophy of Science in the Seventeenth and Eighteenth Centuries_; >Kluwer 1988, pp. 327-350), Jardine proposes that we reconsider the >history of science as the history of the "validation and invalidation >of questions." One reason that Oken and Schelling seem so strange to >us, Jardine suggests, is that they addressed "what are for the most >part, from our standpoint, _unreal_ questions" (338). I offer a couple of additional items here, first a quotation from the philosopher John Dewey about questions/problems. Dewey was a representative of the pragmatist school of philosophy which was much influenced by Darwin and historical thinking, and this quotation appears in Dewey's essay on _The Influence of Darwinism on Philosophy_ (New York, 1910): Old ideas give way slowly, for they are more than abstract logical forms and categories. They are habits, predispositions, deeply engrained attitudes of aversion and preference. Moreover, the conviction persists -- though history shows it to be a hallucination -- that all the questions that the human mind has asked are questions that can be answered in terms of the alternatives that the questions themselves present. But in fact intellectual progress usually occurs through sheer abandonment of questions together with both of the alternatives they assume -- an abandonment that results from their decreasing vitality and a change of urgent interest. We do not solve them: we get over them. Old questions are solved by disappearing, evaporating, while new questions corresponding to the changed attitude of endeavor and preference take their place. (The reason I happen to know this particular quotation, coincidentally enough, is that I used it in a paper of my own on the species "problem", in which I argued that it is a problem of the sort that needs to be gotten over rather than solved.) Second, in the context of studying questions and problems (from an historical point of view) it is interesting to note that one person who advocated such an approach was the philosopher Robin Collingwood, one of the rather marginalized figures who spent a good deal of time writing on the philosophy of history. And like Jardine, who as Polly mentioned began his career as a systematist, Collingwood earlier in the century worked both as an archeologist (Roman Britain was his specialty) and as a philosopher. An accessible and brief account of Collingwood's views can be found in the chapter "Question and Answer" in R. G. Collingwood, _An Autobiography_ (Oxford, 1939). A later reprint of Collingwood's autobiography (1978) contains an introduction by Stephen Toulmin. (By the way, is Nicholas Jardine any relation to Sir William Jardine, prominent 19th-century naturalist and author?) Polly's project on the uses systematists make of the history of their own discipline sounds absolutely fascinating, and I bet it will generate some very interesting results. I have come across a couple of really interesting papers that address how scientists see themselves in historical context, and both might be of interest here: MacIntyre, Alisdair. 1977. Epistemological crises, dramatic narrative, and the philosophy of science. _Monist_, 60:453-472. Rouse, Joseph. 1990. The narrative reconstruction of science. _Inquiry_, 33:179-196. Another paper that gives some consideration to the particular rhetorical aspects of historical science is: Miller, Carolyn S., & S. Michael Halloran. 1993. Reading Darwin, reading nature; or, on the ethos of historical science. Pp. 106-126 in: _Understanding Scientific Prose_ (Jack Selzer, ed.). Madison: University of Wisconsin Press.
