Darwin-L Message Log 35: 84–108 — July 1996
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.

Ahouse) Subject: analogy, archival thoughts (part 2 of 2) A smattering of thoughts on analogs of biological evolution from the DarwinL archives, continued. Holsinger, Kent E. (09/20/93) "Re: Culture, evolution and Lamarck" It strikes me in reading the discussion about the possibility of cultural evolution that an important distinction is being missed, viz. the distinction between Darwin's theory of evolution and his theory of evolution by natural selection. Darwin's theory of evolution consists of the assertion that all of life's diversity can be explained as a result of descent with modification from a a single common ancestor. Descent with modification is the _only_ process specified. It includes both the branching of lineages and transformation within lineages. It doesn't specify anything about the mechanism that produces the branching or the transformation. In fact, as Ernst Mayr is fond of pointing out, Darwin mostly ignored the problem of how branching happens, focusing instead on the mechanics of transformation within lineages. Darwin's theory of natural selection is one mechanism by which evolutionary change can happen. It is the idea that types with a superior "fitness" will be more greatly represented in succeeding generations than those with a lesser fitness. It is _not_ the only mechanism of evolutionary change, nor is it the only mechanism that Darwin proposed. Darwin envisioned both the inheritance of acquired characteristics and use & disuse of parts as important sources of evolutionary change. We now know that additional processes, like genetic drift, can lead to evolutionary change in a population in the absence of natural selection. Taking this distinction as a given, I can see no reason why we can't talk about (at least certain forms of) cultural evolution. It may be difficult to define the characteristics that are changing, but ask any biological taxonomist how they define a "character" of an organism and you'll see that the problem is not unique to culture. Given that we can identify some characteristics of a culture, say language practices, and given that those characteristics change over time it seems likely to me that the changes can be understood in the broad framework of descent with modification. In fact, my limited understanding of linguistics suggests that this is precisely the case, the similarity of Romance languages being due to their common heritage in classical Latin and the resemblance of Germanic, Romance, and other languages being due to their common heritage in Indo-European. There are, of course, interesting ways in which cultural evolution differs from biological evolution, e.g., greater reticulation among lineages (especially now) and the potential for inheritance of acquired characters (what _is_ education, after all?). These differences, however, have to do with the _mechanisms_ responsible for producing descent with modification. Thus, I see cultural evolution as a historical process that will share some of the features of biological evolution, simply because both are a process of descent with modification, even though the mechanisms underlying biological and cultural evolution are very different. Gerson, Elihu M. (09/23/93) "Heritability and cultural evolution" On Thu, 23 Sep Richard M. Burian said: >...At least one standard account of heri- >tability makes a trait heritable if there is higher [or, for that matter, >different] correlation between parent and offsping than between random >members of the parental and offspring generations. This way of looking at it puts us squarely in the middle of the ancient correlation-is-not-causaton discussion. Most usages of "heritability" (and similar terms that I've seen) assume or describe some causal connections between the characteristics of one generation and those of another, not just association. Correlations don't tell us anything about the cause of resemblances between parents and children. Thus, for example, if many people come down with an illness simultaneously, it may be impossible to determine from correlational data if the cause is contagion, heritable susceptibility, exposure to an irritant in the water supply, some combination of these, or something else altogether. > All of this removes one potential obstacle to theories of cultural >evolution. But as Holsinger points out, without a serious account of >mechanism of (cultural) evolutionary change, we don't really have such >a theory. True-- and we don't have any plausible theories of cultural evolution. Moreover, I think using the term "heritability" to refer to both biological and cultural transmission runs the risk of confusing processes which are very different in important respects. So I think we need a different term for the more general and abstract process which includes heritability on the one hand (i.e., biological transmission) and heritage or tradition (i.e., cultural transmission) on the other. And it will also be well to keep in mind that there are clearly many subkinds of each kind of transmission. I am particularly concerned to avoid arguments like: the contents of the second draft of my manuscript looks like the first draft of my manuscript, THEREFORE, keyboards (or maybe word processors) are what shapes the contents of manuscripts. Arguments of this form, in which lower-level (often genetic, often psychological) processes are awarded causal efficacy, and higher level (i.e., organizational, political) processes are ignored, are extremly common. They can be, and often are, used to justify the most terrible crimes, including genocide. So I think we should be very very clear in what we say and what we mean when we are dealing with these cross-level problems. I also think it is a good idea to keep in mind that the analysis of cross-level processes is very complex, and cannot be divided into a "so much of this, so much of that" way. Susan Oyama has done an outstanding analysis of nature-nurture controversies from this perspective: "The ontogeny of information", Cambridge U Press, 1985. Holsinger, Kent E. (09/24/93) "Re: Heritability and cultural evolution" Gerson makes a reasonable point in his reply to Burian. Using the term "heritability" to refer to both biological transmission and cultural transmission runs a risk. By failing to distinguish between them, on the basis of the _very_ different mechanisms underlying them, we may unwittingly make use of evolutionary principles that depend on biological heredity when trying to understand cultural evolution. It is important, however, to realize that there will be _some_ commonality between the processes, no matter how different the mechanisms underlying the transmission. Darwin's theory of natural selection, for example, requires only that offspring resemble their parents, i.e., that there is a _correlation_ between parental and offspring phenotypes. It does _not_ require any that any particular mode of transmission underly that correlation. In fact, Darwin got the mode of inheritance completely wrong. To the extent that we can make inferences about the characteristics of an evolutionary process from the fact of transmission alone, there are bound to be similarities between biological and cultural evolution. There are two aspects of cultural transmission that seem to have no counterpart in biological transmission (that I have been able to think of, at least). First, transmission isn't strictly unidirectional, from parent to offspring, in cultural transmission. Second, there is considerable horizontal transmission among individuals. Take attitudes towards homosexuality as an example. (I should note before proceeding that this entire discussion is based only on my _perception_ of attitudes, not on any actual data about them. Still, it serves to illustrate the point.) Attitudes among college-age students towards homosexuality seem clearly influenced by the environment in which they were raised, i.e., by their parents (at least in part). That's classical vertical transmission. However, students' attitudes are also influenced by the attitudes and behavior of their peers. I'm sure we all know of cases where a student who was adamantly anti-homosexual discovers that a friend is gay and, as a result, changes his attitude about homsexual behavior. (Of course, many times attitudes don't change.) That's an example of horizontal transmission. Similarly, parents sometimes change their attitudes about homosexual behavior as a result of learning that their son or daughter is gay/lesbian/bisexual. That's reverse vertical transmission. One of the significant questions in my mind is whether the extent of these alternative modes of transmission is so great that cultural and biological evolution share few interesting properties or if their extent is limited enough that there are significant similarities. Another is whether there are certain classes of cultural evolution, e.g., linguistic evolution, that are more similar to biological evolution than others, e.g., changes in sexual mores. Mayer, Gregory (09/24/93) "Re: Heritability and cultural evolution" In his posting of 23 September, Elihu Gerson cautions us against using the one term heritability for both biological and cultural transmission, for while they are similar, calling them the same thing might obscure important differences. I would like to endorse his call for careful use of language and terminology in discussing these phenomena. While heritability could be expanded in meaning to include cultural transmission, it might well be best to restrict it to its well defined biological meaning. It is not quite right to define heritability (in the quantitative genetics sense), as Richard Burian has, as the correlation of parents and offspring. It is indeed true that parent/offspring correlation is a common experimental design for estimating heritability, but it is not the definition of heritability, nor the best experimental design. Heritability is defined as the proportion of the total variance among individuals (= the phenotypic variance) that is due to genetic variance among individuals. The phenotypic variance also has an environmental component, and the genetic variance can be further decomposed into additive, dominance and interaction components. More complex analyses of the variance to include further complications such as, e.g. genotype/environment correlation, are possible. The key point is that heritability is not just a correlation among parents and offspring (which can be similar for all sorts of reasons), but, by definition, a genetic (in the biological sense) phenomenon. Quantitative geneticists design their experiments so as to be able to estimate the various components, genetic and non-genetic, of the phenotypic variance. Thus if we were interested in the heritability of dialect, the first experiment a quantitative geneticist would think of would be to raise offspring from one dialect group in a different dialect group. Experiments much like this have been done to study song dialects of birds. If we did such an experiment with humans, we would find the heritability to be zero: an American child, raised from birth by a Brazilian family in Brazil, would speak Portuguese. The same, I would wager, would be true of dialects. There is, of course, an interesting cultural transmission of language in our American/Brazilian gedanken experiment, but it does not involve a non-zero quantitative genetic heritability. The second point worth mentioning about this is that heritabilty is an analysis of _variance_, i.e. of differences among individuals, and says nothing about mean values. If we did Richard Burian's study of heritability within a stable dialect, we would again find zero heritability. This time it would not be zero contingently, as in the case of the American child in Brazil (it _could_ have been the case that language was inherited genetically in man, as it is, in part, in some birds; it just happens that it isn't). It would in this case be zero by definition, because there would be no differences among individuals, since, by the setup of the example, they all spoke the same dialect. Again, there would be an interesting cultural transmission of language, but the quantitative genetic concept of heritability would not be a useful analytic tool. Heritability is a way of relating differences among individuals to differences in their genes, environment etc. Those interested in the details of heritability in the quantitative genetic sense should look at D.S. Falconer, 1989, _Introduction to Quantitative Genetics_, Longman, Harlow, Essex, and for an account of the limitations of this approach at R.C. Lewontin, 1974, The analysis of variance and the analysis of causes, _Amer. J. Hum. Gen._ 26:400-411. Rindos, Dave (09/26/93) "Evolution Cultural Capacity" We have been seeing quite a bit on Cultural Evolution here, much of it quite provocative and well-expressed. But, I must admit, by and large, the comments are the usual ones I encounter on this topic. It seems that one of the major concerns is whether any THING exists which can be said to serve as the mode of inheritance and selection for culture. For example: From: "JOHN LANGDON" > To me, heritable implies genetic or some other biologically determined > change. Culture is not heritable and the evolution of culture is not better > than an analogy with organic evolution. What non-genetic systems do you > have in mind? I think it is pretty obvious that those of us working in this field take culture = inheritance system as a given. Defense of this assumption is not really that difficult (visit your local anthropology department :{) ), but no defense can stand against a principled assumption that heredity *must* equal genetics and therefore that non-genetic inheritance systems, BY DEFNITION, cannot evolve. Howevever, let me note that the evolution of the genetic CAPACITY for culture provides us with an interesting starting point in understanding the "naturalness" of the cultural inheritance system, especially for those with genetic-reductionist tendencies. One way to look at this is in terms of what Boyd and Richerson call the "argument from natural origins." My version runs more or less along these lines: Consider that the human *capacity* for culture is the result of GENETIC evolution which resulted in the various morpological changes characteristic of our line relevant to this capacity (the normal stuff about larger brain, etc etc). Put in rather simple terms, we are cultural *only* because our genes permit it. During the evolution of Homo, this genetic capacity for culture, of course, arose by means of normal, genetic evolution. The obvious conclusion to be derived from this observation would be that the *genetic* capacity for culture evolved because the genes permitting culture induced fitness. Consider now that culture is, in its manifestations (as opposed to the capacity) PURELY PHENOTYPIC -- put in other words, the *specific* behaviours induced and transmitted through a cultural system are not *in and of themselves* genetically determined (the obvious example here is language). Hence, *any* genetic selection for the cultural capacity had to the result of selection acting SOLELY upon the mainfestations of that capacity -- the culturally transmitted behaviours themselves. Now given the fact that the capacity for culture DID evolve (humans, after all, are cultural), and given the fact that the establishment of the cultural capacity required genetic change, and taking into account that it was not the CAPACITY per se that was selected (recall, the capacity itself does not exist as a focus for selection, only its manifestations in specific phenotypic behaviours), we are led to to the following: During the evolution of the genetic capacity for culture, (at least some) NON-genetically determined behaviours were of capable of inducing sufficiently high relative fitness to bring about a populational change in the genetic makeup of Homo. "Culturing" hominids were more fit than those whose behaviour was more strictly genetically determined. As a result of the genetic selection which occured, the human capacity for culture was established in our line. Yet the capacity for culture merely means that certain kinds of behaviours are determined by phenotype/phenotype transmission. The *specific* behaviours selected during the evolution of the genetic capacity for culture were NOT (by definition) genetically *determined*. But we must recognise that it must have been these very non-genetically ("culturally") determined behaviours which must have been increasing the fitness of the individuals, else we could never have the evolution of the genetic capacity to perform them. The advantages for coding the determination of certain kinds of behaviours in the phenotypic, cultural, system were sufficiently great to "drive out" the earlier system which presumably had a more direct ("hard-wired") genetic determination for behaviour. From this logic we can be *certain* that CULTURALLY DETERMINED behaviours must be subject to selection -- else we would never have estabished the GENETIC capacity for culture. The genetic capacity could evolve only by means of the selection of the phenotypic, non-genetic, *expressions* of that capacity. From this, we can see that the selection of cultural behaviours was sufficent to bring about what amounts to a revolution in the genetic system of Homo -- culture replaced genes in the determination of much of the specifics of behaviour. Clearly, a lot of genetic fitness can arise from genes "giving up" control over certain kinds of specific behaviours and instead having genes (?"meta-genes?") which ALLOW the phenotypic system of transmission. It therfore seems pretty reasonable to presume that culture as *expressed* in specific behaviours was sufficiently fit that it could bring about this kind of genetic change (else we wouldn't observe culture!). Now to return to the question of "is culture an inheriance system on which selection can act?" It seems that selection of cultural behaviours MUST have occurred in the past -- else we would not have a capacity for culture. Yet AFTER the cultural capacity had been established WHY should we presume that the selection would stop? Certainly feed-back to the genetic system need no longer be occurring, but so what? If the selection of purely phenotypic variants (culture in its various *manifestations*) was sufficently powerful to bring about the GENETIC changes typical of modern Homo (the genetic *capacity* for culture), then why should selection not apply to these same traits afterwards? How in the world would selection "know" that the cultural capacity had been established, and why should selection of these phenotypic traits in their various manifestations, and hence the potential for evolution, cease? The obvious rejoinder would be that "without the genetic feedback there is NO evolution." While this would provide a neat, definitional solution to the problem, it would miss the very point of what I am saying: In the case of the evolution of the genetic cultural capacity, the genetic feedback was merely a CONSEQUENCE of the differing fitness of KINDS of phenotypes (those which were more or less "hard-wired" in the determination of behaviour). GENES, per se, were NOT being selected, phenotypes were. As a consquence of the relative superiority of phenotypic coding, genetic evolution occurred. Those demes capable of phenotypic coding of behaviour and hence of phenotypic evolutionary processes were more successful over time. So, at least in a sense, the evolution of the genetic capacity for culture, was also the evolution of culture as phenotypic inheritance system which could be subject to selection, and hence which could evolve. Had *HEREDITABLE* differences in phenotypically and culturally based fitness NOT correlated with the more "culturing" demes, then the selection of their particular genetic system (the hereditablility of which is NOT under question by even the most ardent doubters of culturally based heredity, selection and evolution) would never have occurred! We would not be cultural animals. Swann, Philip (10/01/93) "Greenfield on Language" I recently completed a "continuing commentary" on the following paper: Greenfield, P. M. (1991) Language, tools and brain: the ontogeny and phylogeny of hierarchically organized behavior. Behavioral and Brain Sciences, 14, 531-95 I have submitted this to BBS for publication and placed a copy on our anonymous ftp server (tecfa.unige.ch, dir /pub/tecfa-working-papers). The original article and my commentary cover a wide range of issues in the biology of language. Comments, arguments and such welcome. If you don't have access to ftp, I can e-mail a copy. Holsinger, Kent E. (10/01/93) " A parallel between linguistic and biological evolution?" Sally Thomason made an interesting observation (something I had always suspected was true, but wasn't sure about): > If you cut off contact between two halves of one speech community, > different changes will occur in the two groups' speech. Almost the same thing can be said in biology: If you cut off contact between two halves of a species, different changes will occur in the two groups. If you subsitute the phrase "gene flow" for "contact," you have (roughly) Ernst Mayr's classical description of the way in which allopatric differentiation occurs. In fact, I wonder whether both of these principles are both instances of a single more general principle. Does it seem reasonable to conclude that the following is true (I'm not entirely sure. I'm just throwing it out for discussion.): 1) Define a population as a group of interacting entities that a) reproduces itself and b) has the property that newly arisen entities within the population have characteristics that resemble, but do not necessarily duplicate, the characteristics of the population. 2) If such a population is divided into two or more groups, so that individuals in a group interact only with other individuals in their group and not with individuals in other groups, then a) the newly produced groups are populations and b) the characteristics of these populations will tend to diverge from one another through time. Actually, it occurs to me that I really have *two* questions about the above scenario. First, is it true? (I think I can make a pretty good argument for its truth in biology, but I'm not so sure about other fields.) Second, if it is true, is it interesting? Does it really tell us something informative, or is it so broad and general as to be uninformative? Langdon, John (10/01/93) "Re: A parallel between linguistic and biological evolution?" > > If you cut off contact between two halves of one speech community, > > different changes will occur in the two groups' speech. > > Almost the same thing can be said in biology: In my perspective, what species and languages have in common is that they are both properties held by populations and not individuals. A species should not be considered adequately defined by a single individual (although of necessity, that is where taxonomists often have to begin). Language is not language unless it is used to communicate among individuals. Therefore when the population is divided and becomes two populations, its property (e.g. language) also becomes two independent entities (two languages). Whether or not these two populations or two languages are different from one another is best answerable in retrospect after divergence has become more visible. > 1) Define a population as a group of interacting entities that > a) reproduces itself and > b) has the property that newly arisen entities within the population > have characteristics that resemble, but do not necessarily duplicate, > the characteristics of the population. > 2) If such a population is divided into two or more groups, so that > individuals in a group interact only with other individuals in their group > and not with individuals in other groups, then > a) the newly produced groups are populations and > b) the characteristics of these populations will tend to diverge from > one another through time. This is true if and only if we assume the changes between generations (under 1b above) will not be the same in both groups. It is easy to see why these are different in both species and languages-- variation within populations and some degree of randomness of changes. However, this assumption probably should be written into the model above. > Second, if it is true, is it interesting? Does it really tell us something > informative, or is it so broad and general as to be uninformative? Probably it is not informative for biologists and linguists who already understood this principle. But perhaps there are other systems that we have not though of as belonging to this class-- e.g. academic "schools" of theory. Gale, George (10/01/93) "Biological and linguistic change" Picard, Marc wrote to me "In regular sound change, expediency is the name of the game. The human vocal apparatus prefers certain combinations of sounds, and that's what speakers unconsciously strive for." I'd like to focus in on the "prefer". Do you mean that certain sound sequences are, in some sense, more difficult than others? I assume that you do mean this, and would like some further sense of what the dfficulty might consist in. For example, in terms of the physical energy required to utter certain sequences, is there a preference for minima? Or, again to speak physically (I'm a philosopher of physics, after all!), is the path length of the sequence of motions in the cords (or other parts of the 'instrument') a minima--a preference? Or, is it just plain DIFFICULT to play the sequence, as, by analogy, certain chords would be difficult to finger on a guitar? Perhaps I'm being too literal here. Maybe by "prefer" Marc meant an esthetic evaluation, as in, the ear prefers to hear certain sounds. That would certainly be plausible, since, for example, the overall 'sound' of e.g., German is quite different from the overall 'sound' of e.g., French. Picard, Marc (10/01/93) "Biological and linguistic change" First, let me state that, to my knowledge, no phonologist has ever attributed any sound change to a desire for euphony or acoustic esthetics or whatever. Second, instead of using the terms 'easy' and 'difficult'in relation to spech sounds and their combinations - something which has proven to be notoriously difficult to measure or quantify in any useful way, as far as I am aware - I think it is much more productive to look at ASSIMILATION, which is the type of sound change I was discussing, as an attempt to get from here to there (an UNCONSCIOUS attempt, obviously) by the shortest possible route, on onehand, and by getting ready for what's coming next as soon as possible, on the other. The problem is that speakers can't see beyond their own noses, so to speak, so that having taken a shortcut here, they will often create a situation that is less than ideal, and which will also have a tendency to be changed. Here is a simple case in point, an example of which could most probably be found in the history of any language. Unstressed vowels have a tendency to be 'slurred' (laxed/reduced to schwa) and then deleted. More often than not, this leads to the buildup of consonant clusters which will almost beg to be reduced, leading to another change. These can pile up, as when Latin AUGUSTUM wound up as French /u/ (written AOUT with a circumflex on the U which indicates that an /s/ used to follow, cf. the family name DAOUST, and pronouncedas a short English 'oo'). _____________________________ _______________________________________________________________________________ <35:85>From ddennett@diamond.tufts.edu Tue Jul 23 16:37:19 1996 Date: Tue, 23 Jul 1996 17:37:17 -0400 (EDT) From: Daniel Dennett <ddennett@diamond.tufts.edu> To: darwin-l@raven.cc.ukans.edu Subject: Re: Reviews of Dennett Here's my reply to Orr, mentioned by Phillip Johnson.

Dennett One Fan's Pratfalls A Reply to H. Allen Orr's "Dennett's Strange Idea," Boston Review, Summer, 1996. When Professor Orr published his hostile review of Darwin's Dangerous Idea in the biology journal, Evolution, last February, I was not pleased. His review was full of falsehoods and misconstruals, but I had no recourse; that journal, like most academic journals, does not permit authors to respond to reviews. Luckily for me, Orr has been so eager to warn the world of my errors that he has restated his attack, with embellishments, in the Boston Review, which has invited me to respond. Months have passed, the damage has been done, but at least I get to set the record straight. I am grateful to Orr for embellishing his attack for the benefit of his lay readers, since these additions vividly expose his own errors and confusions, which were somewhat masked in the more professional version. In what follows I will concentrate on his criticisms of my understanding of his field: biology. I trust the readers of the Boston Review to have seen the flaws in his philosophical criticisms without my help, but a non-biologist might well suspect that, on his home ground, Orr's criticisms are as authoritative and devastating as he makes them out to be. They are not. Before getting to the meat of his criticism, Orr warns readers that my book is marred with factual errors, some scientific and some historical. Population genetic theory, for instance, does not prove that evolution by random change is faster than evolution by natural selection, as Dennett claims. I did indeed misspeak (p.126), but the result was ambiguity, not error. The issue is complicated: it depends on whether you're measuring the (average) speed of departure from a starting point in genetic space, or the speed of attainment of some particular evolutionary product. I meant the former, as the context ought to have made clear (I was in the process of observing that there has been plenty of time in evolutionary history for the sheer genomic diversity observed to accumulate). But I did couch my claim in terms that permitted Orr to put the false reading on it. Score one half point for Orr. He goes on: And it was Darwin's theory of sexual, not natural, selection that he called an 'awful stretcher.' I made no such claim. I entitled a chapter section "Natural Selection--an Awful Stretcher." The vivid epithet comes from Darwin, but it was I who applied it to natural selection. Orr, having already stretched too far in his effort to find a historical error to impute to me, topples over when he tries to elaborate: "Darwin branding natural selection a stretcher is about as plausible as Chomsky branding Universal Grammar a howler." What? Darwin branded sexual selection an awful stretcher in the very act of endorsing it--it is, after all, a special kind of natural selection, not an alternative! Here's what Darwin said (as I noted, when I introduced the term): "It is an awful stretcher to believe that a peacock's tail was thus formed; but, believing it, I believe in the same principle somewhat modified applied to man." Surely Darwin would have agreed, if asked, that natural selection was another awful stretcher he believed in. Orr's remark about Chomsky makes it appear that he thinks Darwin was dismissing sexual selection when he called it an awful stretcher, but I expect he knows better and simply got carried away by his desire to rub it in about my non- existent error. These are the only two "factual errors" he comes up with, and he judiciously grants them the status of "peccadilloes." There are some factual errors in my book that others have pointed out, but since Orr does not brandish any of them in his essay, I think we can conclude that they eluded his scrutiny. Let's turn, then, to his main criticisms about my book's supposed deep misunderstandings of biology. Orr concentrates on my criticism of Gould and Lewontin's famous attack on adaptationism, "The spandrels of San Marco and the Panglossian paradigm." Evolution--what Darwin called "descent with modification"--is an uncontroversial fact, as secure as any in science, but there is still controversy among biologists about just how many of these facts about evolution are to be explained by citing natural selection, the mechanism Darwin proposed as the most important force shaping evolution. To see what the issue is, consider the popular retort of software engineers when somebody finds a flaw in their program: "It isn't a bug, it's a feature." In other words, it's supposed to be that way; it was designed to work like that. Now is everything observable in the biosphere a "feature," an "adaptation" as an evolutionary biologist would call it? Are there no bugs, no undesigned bits, no historical accidents? Of course there are. Everybody agrees on that. Everybody does not agree on how important these non-adaptations are; the greater the role you give to natural selection, the more "adaptationist" you are, and the Gould/Lewontin essay was an attempt to swing opinion the other way. Orr begins by usefully perpetuating some of the misunderstandings I exposed in my discussion of Gould and Lewontin's central architectural metaphor for a non-feature: a "spandrel"--one of the curving wedges of masonry that serve as the transition from the domes of the Basilica di San Marco in Venice to the arches that hold them up. (I find this useful because some critics have wondered if any biologists have actually been confused on this score; my answer is yes--see, e.g., H. Allen Orr.) This is what he says: Although spandrels are often decked out with mosaics, no one would seriously argue that spandrels are there because they provide such swell surfaces for mosaics. Instead, spandrels are there because they have to be--they are, it turns out, the inevitable by-product of putting a dome on rounded arches. "Inevitable by-product"? This is either flat false or true but irrelevant. If by "spandrel" Gould and Lewontin mean the particular structure used in San Marco (properly called a pendentive) then what they say is false; pendentives are one of many options, but they are probably the optimal engineering solution to the problem of supporting the dome--what I would call a Forced Move. In this sense, spandrels (pendentives) are adaptations par excellence. If, on the other hand, Gould and Lewontin mean by "spandrel" just "whatever you put in that place between the dome and the arches," then spandrels are trivially inevitable--you have to put something there. Gould himself has recently opted for this reading, but as I had already pointed out in my book, p272-3, this interpretation also disqualifies spandrels for their role as lead metaphor in Gould and Lewontin's biological argument. In this sense, architectural constraints present a problem, not a solution, in biology as much as in building, and that is where natural selection comes in. This has been much discussed recently, and the architectural engineer Robert Mark, in a fascinating article in the July issue of American Scientist, shows that my own amateur engineering (and architectural history) led me to underestimate the structural requirements for handling the forces of putting a large dome on arches. The pendentives are in fact not just aesthetic adaptations, as I had claimed, but also structural adaptations. So the San Marco "spandrels" are a doubly poor choice for eponymous non-adaptations. The mosaics on the pendentives are aesthetic design choices enabled by prior structural design choices. An example of one adaptation exploiting a prior adaptation hardly strikes a telling blow against adaptationism. But why are we quibbling about these fine points of architectural history? Why, indeed, do I pay such obsessive attention to Gould and Lewontin's attack on adaptationism? Orr expresses his bafflement. Why, after all, should a man hoping to export Darwinism from biology be so obsessed with defending the minutiae of adaptive storytelling within biology? I would not think the legitimacy of, say, cultural Darwinism hangs critically on whether selection is very important in biological evolution (as everyone, including Gould and Lewontin, believe) or is almost exclusively important (as Dennett believes). First, Orr strains to create a gulf that does not exist between me and the run of biologists. What, we may ask, is the difference between "very important" and "almost exclusively important"--the presumably dissenting view he attributes to me? It is Gould and Lewontin, in fact, who have had trouble clarifying their charge. Everybody agrees, as Orr says, that selection is very important, so just what are Gould and Lewontin saying? That it is not as important as some people think? If that had been their message, I would agree with John Maynard Smith that their paper was "on the whole, welcome." Orr quotes this verdict with approval, and so did I (p278), noting, however, that this was not their message--or at least it has not been Gould's version of their message. I think Orr's professed perplexity must be disingenuous. I make it crystal clear why I have to go to all this trouble clarifying these minutiae: Gould has persistently misrepresented the import of the Gould/Lewontin paper outside biology, and many have been taken in. My unshirkable task was to show the non- biologists that they have been seriously misled by Gould about this. In my book I list four propositions that are widely believed by non-biologists to have been demonstrated by Gould. The first two are relevant here: If you believe: (1) that adaptationism has been refuted or relegated to a minor role in evolutionary biology, or (2) that since adaptationism is 'the central intellectual flaw of sociobiology' (Gould, 1993a, p.319), sociobiology has been utterly discredited as a scientific discipline. . . then what you believe is a falsehood. (p.265) Well, are these truths or falsehoods? They are widely believed. Many non-biologists are under the weird misapprehension, thanks to Gould's rhetoric, that one is under no obligation to provide an adaptive account of the evolution of a complex competence or organ--such as human language. In some misguided quarters, indeed, adaptationist explanations of anything are automatically suspect! For more than a year before the publication of my book and on several occasions since then, I have repeatedly requested that he clarify his position on these propositions. Steve Gould is undeniably a Great Communicator. If these propositions are not what he meant, if over-eager readers have misunderstood him, he should find it both obligatory and easy to correct these widespread misapprehensions. If he meant them, he should either defend them against my charge of falsehood, or concede that he has misled his readers. He has not accepted my invitation to clarify his position, so it falls to me to explain to the world, at whatever length it takes, why these are not the take-home messages from Gould and Lewontin's article. The centerpiece of Orr's critique of my defense of adaptationism is his feigned astonishment that I omit any discussion of Motoo Kimura's neutral theory, "the most serious and famous of all challenges to selectionist story-telling." Here he plays a cute rhetorical trick: Boy oh boy, Dennett must be really out of it to have overlooked Kimura's work! Why on earth did he omit this? Was it because he never heard of it? Naw. Or because Kimura's book was too difficult for him to read? Naw. Or because he "doesn't want to let the cat out of the bag" about the fact that biologists have found out that "non-Darwinian" evolution is common? Naw. Having relieved himself of these snide but indefensible suggestions--as he himself so generously acknowledges--he arrives at the obvious truth: "Dennett is interested in Design . . . and the neutralist/selectionist controversy has nothing to say here." Right. It wasn't relevant. Kimura's theory is about typographical change, visible at the molecular level of the genome. As Orr says, "most evolution at the molecular level [my emphasis] is not caused by natural selection, but by 'genetic drift'." Before Kimura, theorists hugely underestimated the possible role of the accumulation of random mutations that are (as Orr notes) functionally equivalent. Kimura's work is wonderful, surprising, and still controversial; it claims (among other things) that the diversity observed at the molecular level could be much more the result of random genetic drift than many theorists--"selectionists"--had thought, but this aspect of selectionism has little or nothing to do with adaptationism, which is why I left it out. Oh, I could have had some fun with the fact that there are indeed some biologists-- Gould and Lewontin come to mind--who have often suggested to the lay public that Kimura's neutral theory is a rival to natural selection as an account of morphologic evolution (the shaping of complex phenotypic features), but as Orr as much as admits, this is not taken seriously among biologists. From all Orr's hooting one might get the impression, by the way, that I had nothing to say on these topics in my book, but in fact, I discuss the role of random genetic drift (p.125-6) and the ubiquitous possibility of typographically different but functionally equivalent genetic recipes for proteins (pp195-6, p287). Where Orr mentions functionally irrelevant differences in varieties of hemoglobin, I mention functionally irrelevant differences in lysozyme. Same points made, right down the line. In fact I also make all the other points about adaptation he goes on to explain for his lay readers, saying "Dennett never confronts these legitimate worries." (All of them? Yes. If you want to test my claim, you can go back and match page 30 of Orr's review with my pages 199, 248-249; I'll spare readers the tedious details.) One last point about Orr's understanding of central concepts in his own field before we turn briefly to the evolution of culture. I say that natural selection is an algorithmic process, and hence is "substrate neutral"--it doesn't matter what material the algorithm is executed in, so long as the recipe is followed. Orr says, correctly, This substrate neutrality argument is supremely important to Dennett. It--and nothing else--explains why selection can be lifted from its historical base in biology. It is what makes Darwinism so dangerous. He goes on: "But Dennett slips here." It is Orr who has slipped, falling flat on his face with his proposed counterexample to my claim that natural selection is a substrate neutral process: "blending inheritance." Orr says: Evolution would quickly grind to a halt, for instance, if inheritance were blending, not particulate. With blending inheritance, the genetic material from two parents seamlessly blends together like different colored paints. With particulate Mendelian inheritance, genes from Mom and Dad remain forever distinct in Junior. This substrate problem [sic] was so acute that turn-of-the-century biologists--all fans of blending inheritance--concluded that Darwinism just can't work. Modern evolutionary genetics was born in 1930 when Sir Ronald Fisher cracked this problem: Population genetics shows that particulate Mendelian inheritance saves the day. It is just the kind of substrate [sic] needed for evolution by natural selection to work. Orr is right that Mendel saved the day for Darwin (a point of history I discuss in somewhat greater detail in my book), but this was a triumph for substrate neutrality! Mendel--and Fisher, too, for that matter--was clueless about what the substrate was. (It's DNA, of course, but that wasn't discovered until 1953, by Crick and Watson.) Mendelian genes are a paradigm case of substrate neutrality; they are pure data structures, whose material composition is irrelevant just so long as they obey the combinatorial rules Mendel laid down. The field of population genetics thrives to this day in almost complete independence of any concern with the nitty-gritty biochemistry of the substrate-- just the way software engineering is conducted by people who need know little about the electronics or physics of their silicon substrate. The problem with blending inheritance is the code, not the substrate; it would be just as hopeless a system to use in evolutionary software engineering as it would be in carbon-based biological evolution. Orr has apparently missed this fundamental point about the abstractness of evolutionary theory, and having missed it, he compounds his confusions when he turns to my exploitation of Richard Dawkins' concept of memes in defense of a Darwinian theory of cultural evolution. His "basic problem" with any attempt at such a theory is that we are "very ignorant of how humans hold ideas in their heads. . . So how can we possibly conclude that the process 'must be' Darwinian?" Well, population geneticists were very ignorant of how organisms held genes in their bodies until recently, but this did not stop Fisher and his colleagues from establishing (in a substrate neutral way) the soundness of the modern synthesis, did it? Orr comes close to contradicting himself here, and doesn't notice. But then his whole discussion of memes is inattentive to detail. Orr says: "the fitness of memes is strangely tautological. While we can often point to ecological reasons why certain genes are fitter than others, a meme is deemed 'fit' only because it is common." This is obviously false, belied by many of the examples discussed in my book. He goes on: "'Elvis is alive' is certainly a fit meme, but it is neither true nor helpful." Has he been paying attention at all? This independence of meme fitness from truth and utility (to us) is the single most important feature of the meme's-eye view of cultural evolution. He continues: "Last, Dennett confesses [sic] that memes often show a Lamarckian, not Darwinian, style of evolution, in that acquired traits get passed on," ignoring the fact that I explain why the "charge" that cultural evolution is Lamarckian misses the mark entirely (p355). Given this obliviousness, his "astonishment" that I would point out how difficult--and maybe impossible--it will be to establish a predictively powerful science of memetics counts for little or nothing. There are many uncontroversially evolutionary phenomena in biology that also defy formal scientific inquiry by being either computationally intractable or bereft of accessible data. Ancient memes, like ancient genes for soft body parts, leave almost no fossil traces. The genetic contributions to many complex abilities in many species are both practically unresearchable and utterly indubitable. For instance, does Orr doubt that there is an evolutionary account--probably forever inaccessible, alas--of the nest-building behaviors in birds? He interprets my cautious discussion of the prospects for memetics as "backing off" from stronger claims about memes, but this retreat is a figment of his imagination. (Aficionados will recognize this trick as an instance of the Gould two-step, exposed by me several years ago in the New York Review of Books.) Orr's other criticisms of memes follow the same pattern as his earlier criticisms of my biology. Once again, he reiterates points I make myself about important problems to be solved, but he treats these problems as clearly insoluble, without giving any arguments or acknowledging that he is following me. He claims that I have overlooked--or deliberately suppressed--trenchant criticisms of memetics from within biology, but he doesn't mention any. I deal with all the criticisms that I have encountered in the literature. If he knows of others, he should have referred to them specifically. One final point: Orr's failure to understand substrate neutrality leads him to miss the otherwise obvious point that in any theoretical analysis of the evolution of a cultural phenomenon, say, morality, there can be complex interplay between genetic and memetic sources of design; substrate neutrality means that the work of evolution can be accomplished in either medium (at different rates, under the same or different selection pressures) and combined in the final product. He apparently thinks that any account of the evolution of morality must either be all genetic or all cultural. He asks, at one point: "Is it obvious that genetic changes are required for such a thing? [No. It is false.] Where are Dennett's trusty memes when we need them? [Right under his nose.]" Orr might want to look at some of the literature I cited on these topics, such as the recent theoretical work by Philip Kitcher, an alumnus of Lewontin's lab. It's substrate neutral, all the way. I will not comment on Orr's critical treatment of the more purely philosophical parts of my book, beyond noting that the charitable interpretation would be that he doesn't understand the difference between serious criticism and the mug's game of quoting out of context. I suppose I must cite at least one instance, so as not to leave unsubstantiated criticisms floating in the air, as he has done: those who are curious may consider as exhibit A his abuse of my discussion of "bait-and-switch" in evolutionary theory. One does not lightly undertake the task of dislodging heroes from their pedestals so that their ideas can be critically assessed in the same arena with the ideas of ordinary mortals. So I expected to be treated fairly roughly by their fans, especially in their home town. Gould and Lewontin and Chomsky have so far all chosen to leave the counter-attack to others, my criticisms being too far beneath their notice, one gathers, to merit any detailed public response. The attacks I have seen to date--of which Orr's is the best, by the way--have been long on sneering and short on substance. It's been surprisingly easy to take, since my task has been far from thankless. Indeed, the thanks I have been receiving from biologists around the world has been most gratifying. _______________________________________________________________________________ <35:86>From DARWIN@iris.uncg.edu Wed Jul 24 00:05:51 1996 Date: Wed, 24 Jul 1996 01:05:43 -0500 (EST) From: DARWIN@iris.uncg.edu Subject: July 24 -- Today in the Historical Sciences To: darwin-l@ukanaix.cc.ukans.edu Organization: University of NC at Greensboro JULY 24 -- TODAY IN THE HISTORICAL SCIENCES 1794: CHRISTIAN HEINRICH PANDER is born at Riga, Latvia.

As to the question of how much space to give each period, or chapter: consider the following remarks of the late Otto Neugebaer. In true classical and medieval tradition, he divided his monumental History of Ancient Mathematical Astronomy (3 vols.) into five *books*. Book III, devoted to Egypt, gets about ten pages. Neugebauer introduces it as follows (p. 559): Egypt has no place in a work on the history of mathematical astronomy. Nevertheless I devote a separate *book* to the subject in order to draw the reader's attention to its insignificance which cannot be too strongly emphasized in comparison with Babylonian and Greek contribution to the development of scientific astronomy. Strong stuff. Nevertheless, it draws attention to another important point--it is the professional and moral responsibility of the historian to make a decision concerning the relative emphasis to give each chapter, phase, period, whatever, of the subject he is dealing with. I don't think the solution lies in any simple ratio of years covered/pages in the book. Since this issue is intimately connected with another--the emphasis given in Western or European writings to Western or European traditions, etc., let me make one more remark--and tie this posting into another issue that has come up, namely the work of Thomas Kuhn, who passed away only recently. IMHO, the way to give the contributions of other, non-western traditions to the human scientific enterprise their due recognition is not simple to allocate *x* more pages to their efforts in the various encyclopaediae, but to attempt to fit the evolution of their scientific cultures into paradigms such as those of Kuhn--to try to see if what Kuhn says applies to all human science, or just modern European science. (All this, of course, to the extent that his ideas are acceptable at all). I have tried ever so gingerly to do this in respect to the work of Moses Maimonides, who worked in Egypt, in the second half of the twelfth century (a few pages of an article I published in Israel Oriental Studies, vol 13, 1993, contain some very brief remarks). In short, I reject the two extremes--the mushy fuzzy all things are just constructs, etc.; and the attempt to avoid judgment by dry criteria; and I call upon historians (who are not strictly speaking *scientists*) to exercise judgment, explain their decitions, and take responsibility for their writings.

Indeed. The majority of the humanities and even social science professors with whom I have discussed the adaptationist program have pointed to Gould's popular books as proof positive that biologists have "rejected" the primacy of natural selection in the evolutionary process. This, of course, is simply not true. While Gould may not have meant to have conveyed this naive vision of evolutionary science to non-scientists, he has very effectively done so!

The easiest way to see this in 2 dimensions (i.e. on paper) is to compare a photograph of the earth from space to the projection. Better yet, look at a globe, and see the 3 dimensions. There are other equal or near equal area projections that do not distort shape as much. Also, the projection was devised by someone else earlier, but not used much other than by Peters. The sources for this are various cartography books I've flipped through; the only author I can recall is John Campbell, but I'm not sure it was in his book that I got this information.

In English, we draw analogies between motion in space and motion in time. We literally say "the future lies ahead," and "looking backward" means "considering our past." If we imagine ourselves physically traveling through time during our lives, we normally "look to the future" and, I propose, see ourselves as walking "forward" in time. We try to put troublesome events in the past "behind us," so that the path before us (in the future) is unobstructed. The Chinese also equate space and time, but in a different way. In Chinese, the same character ("qian" second tone in HanYu PinYin; "mae" in Japanese) is used both for "front" and "forward" in space, AND "earlier" in time. Similarly, the antonym character ("hou" fourth tone in Mandarin; "ushiro" and "ato" in Japanese) means both "behind" and "later". This gave me immense trouble when I was starting to learn Mandarin, because it is the reverse of the English relationship! Now, the analogy between time and space is pretty pervasive in all cultures that I know; and I think it's amazing that the analogies are inverse between languages. However, even within one language there are inconsistencies in the analogy. In English, the word "before" functions like Chinese "qian": it can mean "in front of me" or "happened earlier." And in Chinese, "xiang qian kan," which one might say to a friend who's had recent troubles, literally "look forward," does in fact mean "look to the future." Actually, the differing analogies seem to come from a variation in reference frame. If I look as an impassive observer (NOT one in the middle of a metaphorical passage through time) at several events coming up in the future: (time --->) me.....................a.....B......c............. it certainly does look like event a is "before" B in both temporal and physical senses, and that event c is both "behind" B and "after" it, just like the Chinese would naturally say. But if I, the observer, am looking at things relative to my OWN "walk" through time, -> ...............a.........ME..........b............ then I am facing event b, which is ahead of me in my future. Behind me is event a, in the past, just like we normally say in English. Whether this is evidence of greater SELF-centeredness in Western (at least English-language) culture than in Asian culture may be a question best left unanswered. And, a final thought: the first time I asked my Chinese teacher about this, he replied that of COURSE events in the future correspond to the "back," and vice versa: we can see what's in front of us, just like we know what's happened in the past; but we can see neither the future nor what's behind us.

That way, the number of years on a page shrinks as population grows. Similarly, except to a geologist it makes sense for an atlas to give more and bigger maps of Europe than of Siberia: the number of people to a page ought to be roughly constant. Another quibble with the Peters Projection: the aspect ratio is too low. A case can be made for drawing the equator twice as long as a meridian (true average length), or pi times (true length at the equator) ... there may be other "ideals"; but the Peters atlas uses a ratio <2, and I can't see a good reason for it.

In my research I have been tracking down the links between Charles Darwin's readings and contacts in political economy at the time of his struggles over the problems of learning, habit, and moral sense, and their relation to the problems of evolution by descent (i.e. his 1838 deliberations and musings). Most interesting among these contacts are his readings of the work of Harriet Martineau. Marineau was a sharp student of the emerging science of economics, and here writings on this subject outsold other writers of the period by a wide margin, include such notables as Mill and Dickens. What I found most interesting is Martineau's method, here claims about the differing methods of the natural and the moral & political sciences. In the context of our recent communications on the role of narrative in science, and in the historical sciences in particular, what stuck out was Martineau's method of presenting economics ideas in the form of particular instances and what she called 'illustrations'. Martineau began her work with only a limited background in economics, writing on popular topics discussing such things as changes in the division of labor over time, etc., building on the spatterings of Adam Smith and others that she had run into. But shortly thereafter, in 1927, Martineau ran across Jan Marcet's _Conversations on Political Economy_. Martineau, in here _Autobiography_, recalls: (quoting from _Harriet Martineau: First Woman Sociologist_ by Susan Hoecker-Drysdale, Oxford: Berg. 1992). "great was my surprise to find that I had been teaching [Political Economy} unawares, in my stories about Machinery and Wages. It struck me at once that the principles of the whole science might be advantageously conveyed in the same way -- not by being smothered up in a story, but by being exhibited in their natural workings in selected passages of social life. It has always appeard very strange to me that so few people seem to have understood this. Students of all manner of physical sciences afterwards wanted me to 'illustrate' things of which social life (and therefore fiction) can afford no no illustration. I used to say till I was tired that none but morel moral and political science admitted of the method at all. (_Auto., I: 138). I strikes me, however, than in fact this is just also the method that Darwin used to explain and support his own conception of the science of biology "the whole science advantageously conveyed in or by being exhibited in the natural workings in selected passages of biological life", hense Darwin's later careful particular studies of earthworms, etc. What I am looking for is direction to anything in the literature discussing Harriet Martineau and here work in political economy and scientific method (she was a translator of Comte) in connection with Darwin and his explanatory project. Any help would be appreciated.

Gell-Mann writes: "The complexity at a given time of an evolving system (whether a complex adaptive system or a nonadaptive one) does not supply a measure of what levels of complexity it or its descendents (literal or figurative) may attain in the future. To fill that need, we introduced earlier the concept of potential complexity [i.e. when a modest change in a scheme permits a complex adaptive system to create a great deal of new effective complexity over a certain period of time, the modified schema can be said to have a greately increased value of potential complexity with respect to that time interval.] To define it, we consider the possible future histories of the system and average the system's effective complexity at each future time over those histories, with each one weighted according to its probability. (The natural unit of time for this purpose is the average interval between random changes in the system.) The resulting potential complexity, as a function of time in the future, tells us something about the likelihood that the system will develop into something highly complex by that time, perhaps even by spawning a whole new kind of complex adaptive system. In the example we discussed earlier, potential complexity would distinguish emerging humans from the other great apes, even through their effective complexity at the time was not much different. Likewise, a planetary surface with a significant probability of generating life within a certain time would be distinguished from one on which life was not a serious possibility."

In the course of my research I found that Hennig obviously misunderstood the method of *reciprocal illumination* which he cites from an ethnologist in his 1950 book (p.26). In 1966 (*Phylogenetic Systematics*) he mentioned this method several times. On p.21 he characterizes it as *checking, correcting, and rechecking of the Anglo-Saxon authors*. This phrase is literally taken from Klaus Guenther's contribution to *Fortschritte der Zoologie* 1956, vol 10 p.48. In my opinion, the method of *reciprocal illumination* as described by e.g. Wilhelm Dilthey is by no means identical with *checking, correcting, and My questions to the group: 1. Does anybody know of *Anglo-Saxon authors* who translated or circumscribed *wechselseitige Erhellung* (reciprocal illumination) by *checking, correcting, and rechecking* before 1956? 2. Could anybody tell me who first equalized *reciprocal illumination* to the *hermeneutic circle* or *hermeneutic spiral*, respectively? I see that the whole affair immediately touches the problem of proper methodology in historical science, but I do not want to go into this discussion right here. Thank you for any comment.

That's not what you asked for, but it's a start toward understanding Gould.

Schmidt - Werner Winter Assisted by L.Isebaert (Bibliographical Editor) and Jens Elmegaard Rasmussen (Executive Editor) In persuance of a congressional decision made at the Tocharian Colloquy held by the Indogermanische Gesellschaft at Saarbruecken in October 1995, a new editorial board has been formed with the objective to issue the journal _Tocharian and Indo-European Studies_ (TIES) which was discontinued by the untimely death of its founder Joerundur Hilmarsson in 1992. Explorations into the possibility of continuing the journal on Icelandic hands having proved negative, the plan is now to bring out the journal in Copenhagen in a shape and at a price not too much out of comparison with its earlier policy. Due to old and sentimental connections between Iceland and Denmark, it just may be realistically hoped that the Danish government will allot the necessary fundings to the project. An indispensable condition, however, is that there exist a full manuscript of the first volume by October 1st of this year. Therefore, authors are urged to send manuscripts for publication in TIES, Vol.7 as soon as possible, and not later than August 1st, if need be in preliminary form to allow a final touch to be given during the last weeks available for the editorial preparations. This is admittedly a very tight schedule, but we feel it is in everybody's interest that we seize the present opportunity rather than wait for the next chance which is a whole year later. And indeed, the lack of the journal just may have led to an accumulation of ready or semi-ready papers for which the proper outlet can now be provided. You will be doing a great favour to the community of Tocharian and Indo-European studies and a continued tribute to the memory of Joerundur Hilmarsson by sending a paper to the address printed below. If you can, please help us in the process by adding a diskette; you will cause the least amount of problems by using WordPerfect 5.1, but most systems can be handled, and anything is helpful. If you indicate an e-mail or fax address, the executive editor can give you the board's decision on your paper within two or three weeks. The typographical appearance of the volume will be slightly standardized, but as a matter of principle the choice of textual organization is free. What we need now, is the papers themselves, we can do aesthetics later. We strongly appeal to scholars in and around the intersection of Tocharian and Indo-European studies to receate the important journal that TIES used to be. This is a job that deserves to be done, and together we can do it.
