Preface THIS Bow( has come into existence for both theoretical andpractical reasons. Despite the extraordinary successes of mechanistic reduction- ist molecular biology, there has been a growing discontent in the last twenty years with simple Cartesian reductionism as the universal way to truth. In psychology and anthropology, and especially in ecology, evolution, neurobiology, and developmental biology, where the Carte- sian program has failed to give satisfaction, we hear more and more calls for an alternative epistemological stance. Holistic, structuralist, hierarchical, and systems theories are all offered as alternative modes of explaining the world, as ways out of the cul-de-sacs into which re- ductionism has led us. Yet all the while there has been another active and productive intellectual tradition, the dialectical, which is just now becoming widely acknowledged. Ignored and suppressed for political reasons, in no small part be- cause of the tyrannical application of a mechanical and sterile Stalinist diamat, the term dialectical has had only negative connotations for most serious intellectuals, even those of the left. Noam Chomsky once remarked to one of us, who accused him in a conversation of being in- sufficiently dialectical, that he despised the term and that in its best sense dialectics was only another way of saying "thinking correctly." Now dialectics has once again become acceptable, even trendy, among intellectuals, as ancient political battles have receded into distant mem- ory. In psychology, anthropology, and sociology, dialectical schools have emerged that trace their origins to Hegel. In biology a school of dialectical analysis has announced itself as flowing from Marx rather than directly from Hegel. Its manifesto, issued at the Bressanone Con- ference in 1981 by the Dialectics of Biology Group, began, "A strange fate has overcome traditional Western philosophy of mind." The Bres- sanone Conference did show the power of dialectical analysis as a cri- viii PREFACE tique of the current state of biological theory, although it left for the fu- ture the constructive application of a dialectical viewpoint to particular problems and, indeed, an explicit statement of what the dialectical method comprises. As biologists who have been working self-consciously in a dialectical mode for many years, we felt a need to illustrate the strength of the dia- lectical view in biology in the hope that others would find a compelling case for their own intellectual reorientation. The essays in this book are the result of a long-standing intellectual and political comradeship. It began at the University of Rochester, where we worked together on theoretical population genetics and took opposite views on the desir- ability of mixing mental and physical labor (a matter on which we now agree). Later, working together at the University of Chicago and now at Harvard, in Science for Viet Nam and Science for the People, we have had more or less serious disagreements on intellectual and politi- cal tactics and strategy. But all the while, both singly and in collabora- tion, we have worked in a dialectical mode. Each of us separately has published a book that is dialectical in its explication, in the formulation of its problematic, and in the analysis of solutions (Richard Levins, Evolution in Changing Environments [Princeton University Press, 1968]; Richard Lewontin, The Genetic Basis of Evolutionary Change [Columbia University Press, 1974]). We believe that the considerable impact of these books, the one in ecology and the other in evolutionary biology, is a confirmation of the power of dialectical analysis. Both separately and together we have published scores of essays, applying the dialectical method, sometimes explicitly, sometimes implicitly, to scientific and political issues and to the relation of one to the other. In- deed, it is a sign of the Marxist dialectic with which we align ourselves that scientific and political questions are inextricably interconnected— dialectically related. This book, then, is a collection of essays written at various times for various purposes and should be treated by the reader accordingly. Ex- cept for their grouping under general categolies, the chapters do not have an ordered relation to one another. Material from some essays is recapitulated in others. The book does not follow a single logical devel- opment from first page to last but rather is meant to be a sampler of a mode of thought. That is why we have called it The Dialectical Biolo- gist rather than Dialectical Biology, which would announce a single co- herent project that we do not intend. od 1 PREFACE ix The particular essays we have chosen reflect a purely practical concern. Over the years much of what we have written has appeared in languages other than English and in publications not usually seen by biologists. We have repeatedly sent out photocopie of worn manuscripts, either in response to a request by someone who has heard a rumor of a certain essay or in an attempt to explicate a position. It seemed only sensible to collect these hard-to-find essays in one place, especially since they of- ten represent the best expression of our point of view. We have taken the opportunity to do some editing. For the most part the changes are trivial, but in a few cases we have added some fresh material or inserted paragraphs from other essays to illuminate the argument. In one case, we have eliminated a large chunk of irrelevant didactic material. After collecting these essays, we were dissatisfied. The assembled work illustrated the dialectical method, but it did not explain what dia- lectics is. Since the book is designed to be read by dissatisfied Carte- sians, ought we not explicitly state our world view? Except for a sketch of it in "The Problem of Lysenkoism," we nowhere touched on the subject. We then set about to write a chapter on dialectics—only to dis- cover that in twenty-five years of collaboration we had never discussed our views systematically! The final chapter in this book is an attempt to make explicit what had been implicit in our understanding. It is only a first attempt. Like everything else, it will develop in the future as a con- sequence of its own contradictions. We would like to express our gratitude to Michael Bradie, whose se- vere criticism improved the last chapter. We are immensely grateful, too, to Becky Jones, who helped make manageable order from a chaos of manuscripts, revisions, and additions.

Beginning sporadically in the thirteenth century and culminating in the bourgeois revolution of the seventeenth and eigh- teenth, the structure of society has been inverted from one in which the qualities and actions of individuals were defined by their social posh tion to one in which, at least in principle and often in practice, individ- uals' activities determine their social relation. The change from a feu- dal world in which cleric and freeman, when they engaged in an exchange, were each subject to the laws and jurisdiction of his own sei- gneur, to a world in which buyer and seller confront each other, defined only by the transaction, and both subject to the same law merchant; from a world in which people were inalienably bound to the land, and the land to people, to a world in which each person owns his or her own labor power to sell in a competitive market—this change has redefined the relation between the individual and the social. The social ideology of bourgeois society is that the individual is onto- logically prior to the social. Individuals are seen as freely moving social atoms, each with his or her own intrinsic properties, creating social in- teractions as they collide in social space.

  • From Fox Keller, Back to Leibniz and on to Darwin
    Leibnizian Analysis in Metaphysics, Mathematics, Physics, Geology and Biology: From Fox Keller, back to Leibniz and on to Darwin Emily R. Grosholz I. Introduction The world of classical physics proposed a view of nature where systems behaved like machines: they were reducible to their parts, governed by universal laws (which were moreover time-reversal invariant), and thus representable by an axiomatized discourse where predictable events could be deduced, given the correct boundary conditions. Thus, the philosophers of science of the early and mid-twentieth century happily offered the Deductive-Nomological Model of Explanation (and Prediction). It fit Newton’s Principia, Book I, Proposition XI pretty well. However, it doesn’t really account for Book III, the development of the theory and practice of differential equations, the n-body problem, electro-magnetic phenomena, thermodynamics, atoms, galaxies or the expanding universe, limitations that even Thomas Kuhn, author of the revolutionary book The Structure of Scientific Revolutions, (University of Chicago Press, 1962) played down. But the philosophers did notice that the Deductive-Nomological Model of Explanation wasn’t a very good fit for biology, as after Darwin it struggled to account for natural history with its attendant one-way temporality, the emergence of novelty, and the intentionality and nested downwards complexity of living things, that seemed so stubbornly un-machine-like. The discovery of DNA and the rise of a new kind of machine, the computer, briefly encouraged philosophers (and scientists) to think that biology might finally look like a real science, populated by tiny robots that lend themselves to axioms and predictions; but, alas.

  • How a Generation Was Misled About Natural Selection
    Gabora, L. (2011). How a Generation Was Misled About Natural Selection. Psychology Today (online). http://www.psychologytoday.com/blog/mindbloggling How a Generation Was Misled About Natural Selection Subtitle: Natural Selection: How it Works, How it Applies to Culture Liane Gabora Department of Psychology, University of British Columbia Okanagan Campus, Arts Building, 333 University Way, Kelowna BC, V1V 1V7, CANADA For 'Mindbloggling' column, Psychology Today Abstract This article explains how natural selection works and how it has been inappropriately applied to the description of cultural change. It proposes an alternative evolutionary explanation for cultural evolution that describes it in terms of communal exchange. When science is explained to the general public it is necessary to simplify. Inevitably details get left out, details that some consider important, and the ‘sexy' parts of the story get played up. But so long as the overall picture is more or less right, scientists generally appreciate the efforts of popular science writers, the press, and in some cases their fellow colleagues, to make their work accessible to a wider audience. The public in turn benefits from the opportunity to see the world they live in from a new perspective, and consider questions they might not otherwise have considered. Sometimes, though, the baby gets thrown out with the bathwater. The ‘babyless' version of a scientific story may be a hit nonetheless. Unless one has advanced training in a highly specialized area of a scientific discipline, it may appear to make sense. In most cases, the 1 misrepresentation of science doesn't make much difference; life goes on as normal.

Both series were founded by Dr. Bryant Walker, Mr. Bradshaw H. Swales, and Dr. W. W. Newcomb. Occasionally the Museum publishes contributions outside of these series. Beginning in 1990 these are titled Special Publications and Circulars and each are sequentially numbered. All submitted manuscripts to any of the Museum’s publications receive external peer review. The Occasional Papers, begun in 1913, serve as a medium for original studies based principally upon the collections in the Museum. They are issued separately. When a sufficient number of pages has been printed to make a volume, a title page, table of contents, and an index are supplied to libraries and individuals on the mailing list for the series. The Miscellaneous Publications, initiated in 1916, include monographic studies, papers on field and museum techniques, and other contributions not within the scope of the Occasional Papers, and are published separately. Each number has a title page and, when necessary, a table of contents. A complete list of publications on Mammals, Birds, Reptiles and Amphibians, Fishes, Insects, Mollusks, and other topics is available.

  • The Fearless Vampire Conservator: Phillip Kitcher and Genetic Determinism*
    The Fearless Vampire Conservator: Phillip Kitcher and Genetic Determinism* 1. Introduction Genetic determinism is the idea that many significant human characteristics are rendered inevitable by the presence of certain genes; that it is futile to attempt to modify criminal behavior or obesity or alcoholism by any means other than genetic manipulation. Recent discussion of human cloning has revealed how real a possibility genetic determinism seems to many people. Surveying this discussion, developmental biologist Lewis Wolpert was amused to see so many ‘moralists who denied that genes have an important effect on behavior now saying that a cloned individual’s behavior will be entirely determined by their genetic make-up’ (Wolpert, 1998). His observation is accurate, and the vehemence of many attacks on behavioral genetics probably reflects an underlying belief that if genes affect behavior at all, then they must determine it. In fact, genes are very unlikely to be deterministic causes of behavior, for reasons I will come to in a moment. But if genetic determinism is unlikely to be true, why are we as a community so afraid of it? Wolpert seems to think that moral and political commentators on biology are simply ignorant, but the facts of which they are supposedly ignorant have been widely available for a very long time. Perhaps there is more to the strange persistence of genetic determinism. The psychologist Susan Oyama has famously compared arguing against genetic determinism to battling the undead: “But wait,” the exasperated reader cries, “everyone nowadays knows that development is a matter of interaction. You’re beating a dead horse.

  • Ser Judía Y Puertorriqueña En La Obra De Aurora Levins Morales
    116 | Cuaderno Internacional de Estudios Humanísticos y Literatura:CIEHL International Journal of Humanistics Studies and Literature La doble identidad cultural: ser judía y puertorriqueña en la obra de Aurora Levins Morales Amarilis Hidalgo de Jesús Bloomsburg University of Pennsylvania El estudio de la temática hebrea o literatura judía en la literatura puertorriqueña ha sido generalmente obviado por la crítica literaria dentro y fuera de Puerto Rico, o su mención o estudio ha sido minimizado. No sólo ha existido una relación entre la comunidad hebrea y Puerto Rico desde hace muchos años,1 sino que también en la primera parte del siglo XX surgió un vínculo social y económico entre la comunidad judía sefardita de Nueva York,2 debido a sus raíces judeo españolas o portuguesas, y después la comunidad Ashkenazi,3 y la diáspora puertorriqueña en la ciudad. Los lazos, historias y circunstancias culturales de dichas comunidades quedaron plasmadas en algunas obras de los escritores puertorriqueños en Nueva York o en la de sus decendientes. Sin embargo, proponer aquí que ha habido, tanto en Nueva York como en Puerto Rico, una gran cantidad de escritores judeo-puertorriqueños es plantear una falacia, aunque sí es cierto que en el trayecto de la historia literaria puertorriqueña han surgido voces literarias de extracción cultural y religiosa judeo-puertorriqueña. De estas obras se tiene conocimiento de la poco conocida historia oral del personaje principal, un judío-puertorriqueño, de Los infortunios de Alonso de Ramírez de Carlos de Sigüenza y

  • Darwin & Progress
    Darwin & Progress Robert J. Richards, reply by Richard C. Lewontin December 15, 2005 Issue New York Review of Books In response to: The Wars Over Evolution from the October 20, 2005 issue To the Editors: In his review of Michael Ruse’s Evolution– Creation Struggle and Peter Richerson and Robert Boyd’s Not by Genes Alone [NYR, October 20], Richard Lewontin offers typically insightful analyses of the conflict that has arisen between creationists and IDers on the one hand and evolutionary biologists on the other. As well, he offers salutary cautions about the application of general models of cultural change based on evolutionary theory. He may be quite right that a deep fear of meaninglessness urges many individuals to fly to higher, governing powers and to reject the Darwinian slough of chance. Though Lewontin seems to agree with Ruse that some scientists mount the pulpit in trying to extend evolutionary considerations into all corners of human life, he yet chides him for locating the nub of the dispute in two different notions of progress, that characterizing Darwinism and that endemic to the old-time religion—the one leading nowhere in particular, the other to the ultimate transformation. Lewontin supposes that Darwin kept the ideology of progress from sullying his own theory. He offers as an index of Darwin’s freedom from taint the presumed fact that the word “evolution” (which in the embryological domain had been used to describe a predetermined unfolding) is absent from the first edition of the Origin. Well, not exactly. Rather famously the last sentence of the book hits the rhetorical high mark with “endless forms most beautiful and wonderful have been and are being evolved.” Later editions do not shy from use of the noun form of the word, nor does the Descent of Man.

  • Adaptationism
    Adaptationism Peter Godfrey-Smith and Jon F. Wilkins For the Blackwell Companion to the Philosophy of Biology [Draft K, Final. July 2006] 1. Introduction 2. The Development of the Debate 3. Varieties of Adaptationism 4. The Role of Zoom and Grain 1. Introduction The "adaptationism" debate is about the role of natural selection in relation to other evolutionary factors. The term "adaptationist" is used for views that assert or assume the primacy, or central importance, of natural selection in the project of explaining evolutionary change. This "central importance," however, can take a variety of forms. The debate can also involve questions about how natural selection operates, and what sorts of outcomes it tends to produce. But most discussion of adaptationism is about the relative significance of selection, in comparison with the various other factors that affect evolution. The term "adaptationism" is only a few decades old, but the debate itself is an extension of long-running debates that reach back to the early days of evolutionary theory in the late 19th century. Darwin himself constantly fine-tuned his claims about the relations between natural selection and other evolutionary factors, especially in successive editions of the Origin of Species. Many of the topics covered in recent debates can also be recognized in debates about gradualism, the role of mutation, and the significance of 1 Mendelism to evolutionary theory in the early 20th century (Provine 1971). During the early years of the "evolutionary synthesis," the debate between R. A. Fisher and Sewall Wright was in large part a debate about the role of subtle non-selective factors such as population structure and random drift (Fisher 1930, Wright 1932).
