Thomas S. Kuhn’s The Structure of Scientific Revolutions was a watershed event when it was published in 1962, upending the previous understanding of science as a slow, logical accumulation of facts and introducing, with the concept of the “paradigm shift,” social and psychological considerations into the heart of the scientific process. More than fifty years after its publication, Kuhn’s work continues to influence thinkers in a wide range of fields, including scientists, historians, and sociologists. It is clear that The Structure (...) of Scientific Revolutions itself marks no less of a paradigm shift than those it describes. In Kuhn’s “Structure of Scientific Revolutions” at Fifty, leading social scientists and philosophers explore the origins of Kuhn’s masterwork and its legacy fifty years on. These essays exhume important historical context for Kuhn’s work, critically analyzing its foundations in twentieth-century science, politics, and Kuhn’s own intellectual biography: his experiences as a physics graduate student, his close relationship with psychologists before and after the publication of Structure, and the Cold War framework of terms such as “world view” and “paradigm.”.

"All art should become science and all science art; poetry and philosophy should be made one." Friedrich Schlegel's words perfectly capture the project of the German Romantics, who believed that the aesthetic approaches of art and literature could reveal patterns and meaning in nature that couldn't be uncovered through rationalistic philosophy and science alone. In this wide-ranging work, Robert J. Richards shows how the Romantic conception of the world influenced (and was influenced by) both the lives of the (...) people who held it and the development of nineteenth-century science. Integrating Romantic literature, science, and philosophy with an intimate knowledge of the individuals involved—from Goethe and the brothers Schlegel to Humboldt and Friedrich and Caroline Schelling—Richards demonstrates how their tempestuous lives shaped their ideas as profoundly as their intellectual and cultural heritage. He focuses especially on how Romantic concepts of the self, as well as aesthetic and moral considerations—all tempered by personal relationships—altered scientific representations of nature. Although historians have long considered Romanticism at best a minor tributary to scientific thought, Richards moves it to the center of the main currents of nineteenth-century biology, culminating in the conception of nature that underlies Darwin's evolutionary theory. Uniting the personal and poetic aspects of philosophy and science in a way that the German Romantics themselves would have honored, The Romantic Conception of Life alters how we look at Romanticism and nineteenth-century biology.

Several scholars and many religiously conservative thinkers have recently charged that Hitler’s ideas about race and racial struggle derived from the theories of Charles Darwin (1809-1882), either directly or through intermediate sources. So, for example, the historian Richard Weikart, in his book From Darwin to Hitler , maintains: “No matter how crooked the road was from Darwin to Hitler, clearly Darwinism and eugenics smoothed the path for Nazi ideology, especially for the Nazi stress on expansion, war, racial struggle, and racial (...) extermination.” In a subsequent book, Hitler’s Ethic: The Nazi Pursuit of Evolutionary Progress, Weikart argues that Darwin’s “evolutionary ethics drove him [Hitler] to engage in behavior that the rest of us consider abominable.” Other critics have also attempted to forge a strong link between Darwin’s theory and Hitler’s biological notions. In the 2008 film “Expelled,” a documentary defense of Intelligent Design, the Princeton trained philosopher David Berlinski, in conversation with Weikart, confidently asserts: “If you open Mein Kampf and read it, especially if you can read it in German, the correspondence between Darwinian ideas and Nazi ideas just leaps from the page.” John Gray, former professor at the London School of Economics, does allow that Hitler’s Darwinism was “vulgar.” Hannah Arendt also appears to have endorsed the connection when she declared: “Underlying the Nazis’ belief in race laws as the expression of the law of nature in man, is Darwin’s idea of man as the product of a natural development which does not necessarily stop with the present species of human being.” Put “Darwin” and “Hitler” in a search engine and several million hits will be returned, most from religiously and politically conservative websites, articles, and books.

The eminent historian and philosopher of biology, Michael Ruse, has written several books that explore the relationship of evolutionary theory to its larger scientific and cultural setting. Among the questions he has investigated are: Is evolution progressive? What is its epistemological status? Most recently, in "Darwin and Design: Does Evolution have a Purpose?," Ruse has provided a history of the concept of teleology in biological thinking, especially in evolutionary theorizing. In his book, he moves quickly from Plato and Aristotle to (...) Kant and such British thinkers as Paley and Whewell. His main focus, though, is on Darwin's theory and its subsequent fate. Ruse rests his history on some shaky historical and philosophic assumptions, particularly the unexamined notion that evolutionary theory is an abstract entity that is unproblematically realized in different historical periods. He also assumes that Darwin conceived nature as if it were a Manchester spinning loom -- a clanking, dispassionate machine. A more subtle analysis, which Ruse eschews, might discover that Darwin's conception of nature owed a strong debt to German Romanticism and that he contrived to infuse nature with moral and aesthetic values, not to suck them from nature. Ruse proves he is a thinker to contend with, and this essay is quite contentious. (shrink)

In a series of articles and in a recent book, What Darwin Got Wrong, Jerry Fodor has objected to Darwin’s principle of natural selection on the grounds that it assumes nature has intentions.1 Despite the near universal rejection of Fodor’s argument by biologists and philosophers of biology (myself included),2 I now believe he was almost right. I will show this through a historical examination of a principle that Darwin thought as important as natural selection, his principle of divergence. The principle (...) was designed to explain a phenomenon obvious to any observer of nature, namely, that animals and plants form a hierarchy of clusters. Theodosius Dobzhansky made this the motivating observation of his great synthesizing work, Genetics and the Origin of Species (1937): “the living world is not a single array of individuals in which any two variants are connected by a series of intergrades, but an array of more or less distinctly separate arrays, intermediates between which are absent or at least rare. . .

History of science and philosophy of science are not perfectly complementary disciplines. Several important asymmetries govern their relationship. These asymmetries, concerning levels of analysis, evidence, theories, writing, and training show that to be a decent philosopher of science is more difficult than being a decent historian. But to be a good historian-well, the degree of difficulty is reversed.

While strolling the streets of Amsterdam, Sidney Smith, the renowned editor of the Edinburgh Review, called the attention of his companion to two Dutch housewives who were leaning out of their windows and arguing with one another across the narrow alley that separated their houses. Smith remarked to his companion that the two women would never agree. His friend thought the seasoned editor had in mind the stubborn Dutch character. No, said Smith. Rather it was because they were arguing from (...) different premises. In recent articles, Stephen Ball (1988) and Bart Voorzanger (1987) have objected strongly to my defense of evolutionary ethics. In their reconstruction of my arguments, however, they have assigned to me premises different from those upon which my original defense stood. Their objections may demolish the arguments they have reconstructed, but fortunately my theory does not reside thereon. They have made Dutch objections. (shrink)

In late September 1838, Darwin read Malthus's Essay on Population, which left him with “a theory by which to work.”115 Yet he waited some twenty years to publish his discovery in the Origin of Species. Those interested in the fine grain of Darwin's development have been curious about this delay. One recent explanation has his hand stayed by fear of reaction to the materialist implications of linking man with animals. “Darwin sensed,” according to Howard Gruber, “that some would object to (...) seeing rudiments of human mentality in animals, while others would recoil at the idea of remnants of animality in man.”116 With this link closed, Darwin hung the materialist chain around his own neck, where it rested most uncomfortably. Stephen Gould, supporting Gruber's argument, finds evidence for this reconstruction in Darwin's M and N notebooks, whichinclude many statements showing that he espoused but feared to expose something he perceived as far more heretical than evolution itself: philosophical materialism-the postulate that matter is the stuff of all existence and that all mental and spiritual phenomena are its by-products. No notion could be more upsetting to the deepest traditions of Western thought than the statement that mind-however complex and powerful-is simply a product of brain.117The proferred hypothesis suggests, then, that Darwin was acutely sensible of the social consequences of equating men with animals and therefore mind with brian, and that he thus shied from publically revealing his views until the intellectual climate became more tolerant.The history I have examined makes this hypothesis implausible. Even if Darwin warily explored the implications of his emerging theory in his notebooks, his subsequent study of Fleming, Wells, Brougham, and Kirby should have quieted any trepidation. If these natural theologians did not flinch at seeing human reason prefigured in the mind of a worm, should Darwin have? Moreover, he recognized in his M notebook that the thesis of evolutionary continuity between men and animals did not require an explicit avowal of his conviction that brain was the agent of thought.118 And in any case, his materialism was of a rather benign sort; at least he so expressed it in an annotation in Abercrombie's Inquiries concerning the Intellectual Powers (1838): “By materialism I mean, merely the intimate connection of thought with form of brain — like kind of attraction with nature of element.”119 This belief would have held little terror for British intellectuals, who were quite familiar — some even comfortable-with Locke's anti-Cartesian argument that there was nothing contradictory in supposing God could make matter to think.120 Finally, even if the intellectual atmosphere of early nineteenth-century Britain were inhospitable to Darwin's brand of materialism, there is little reason to believe he breathed a different air at mid-century while preparing his manuscript.That Darwin should not have feared suspicions of materialism, of course, does not mean that he did not. But I think there were other, more persistent sources of anxiety that kept him from rushing to publish: namely, the several conceptual obstacles he had to overcome if his theory of evolution by natural selection were to be made scientifically acceptable. Prominent among these were the problems surrounding his changing notions of instinct.The inertia of his older ideas about instinct at first made it hard for Darwin to gauge how far the theory of natural selection might be applied to behavior. By the early 1840s he finally felt ready to meet the challenge of the natural theologians by providing a naturalistic explanation for the wonderful instincts of animals. In his “Essays” of 1842 and 1844 one sort of instinct is, however, not considered-that of neuter insects. Yet Darwin seems to have appreciated the difficulties such instincts entailed at least by 1843, when he read Kirby and Spence. He simply required time to work out a solution to a problem he initially perceived as “fatal to my whole theory.” Even while writing the “Species Book” in the summer of 1857, he was still juggling several possible solutions compatible with natural selection. It was only a short time before he actually turned to work on the Origin of Species that he appears to have settled on a single explanation for the difficulties posed by the instincts of worker bees and ants. The force of his theory of community selection snapped the last critical support of the creationist hypothesis and, conveniently enough, also fractured the generalized Lamarckian account of the evolution of behavior. These results were worth waiting for. (shrink)

The present study fills a void in research on passion by examining for the first time the role of passion in physiological responses. The aim of the study was to investigate the role of passion, and the mediating role of cognitive appraisals, in the psychological and physiological responses to a stressful situation related to one’s passion. Students, who were passionate for their studies, completed the Passion Scale for their studies and the Cognitive Appraisal Scale. Then, they engaged in an education (...) task under stressful conditions, and a subsequent unrelated leisure task under no-stress. Physiological reactivity was measured throughout the entire session and their perceptions of situational vitality and positive and negative emotions were assessed directly after the education task. Results showed that harmonious passion positively predicted challenge appraisals that, in turn, were positively related to positive emotions, vitality, and positive cardiovascular adaptation while engaging in the stressful education task, but less so with the leisure task. On the other hand, obsessive passion positively predicted threat appraisals. In turn, threat appraisals were positively related to negative emotions, negatively associated with vitality, and not related to cardiovascular reactivity. The present findings suggest that HP creates the onset of an adaptive psychological and physiological response whereas the response is less adaptive with OP. (shrink)

Just before Ernst Haeckel’s death in 1919, historians began piling on the faggots for a splendid auto-da-fé. Though more people prior to the Great War learned of Darwin’s theory through his efforts than through any other source, including Darwin himself, Haeckel has been accused of not preaching orthodox Darwinian doctrine. In 1916, E. S. Russell, judged Haeckel's principal theoretical work, Generelle Morphologie der Organismen, as "representative not so much of Darwinian as of pre-Darwinian thought."1 Both Stephen Jay Gould and Peter (...) Bowler endorse this evaluation, and see as an index of Haeckel’s heterodox deviation his use of the biogenetic law that ontogeny recapitulates phylogeny.2 Michael Ruse, without much analysis, simply proclaims that “Haeckel and friends were not true Darwinians.”3 These historians locate the problem in Haeckel’s inclinations toward Naturphilosophie and in his adoption of the kind of Romantic attitudes characterizing the earlier biology of Goethe. These charges of heresy assume, of course, that Darwin’s own theory harbors no taint of Romanticism and that it consequently remains innocent of the doctrine of recapitulation. I think both assumptions quite. (shrink)

Our image of Darwin is hardly that of a German metaphysician. By reason of his intellectual tradition—that of British empiricism—and psychological disposition, he was a man of apparently more stolid character, one who could be excited by beetles and earthworms but not, we assume, by abstruse philosophy. Yet Darwin constructed a theory of evolution whose conceptual grammar expresses and depends on a certain kind of metaphysics. During his youthful period as a romantic adventurer, he sailed to exotic lands and returned (...) to construct a theory that attacked the citadels of orthodoxy. In the long process of theory construction, he explored difficult philosophical questions—for instance, the nature of reason and the mind-body problem. Moreover, he founded that theory.. (shrink)

One hundred years ago, Flexner emphasized the role of science in medical education. With a 21st-century perspective, the question may be posed anew: is science relevant to medical education and practice? If so, then which areas of science are fundamental to learning and making ongoing decisions in medicine? The answers to these questions should determine what is needed in the preparation of an undergraduate student for medical school.Educators and students alike question the relevance of current premedical requirements, and there is (...) concern that these in fact diminish student interest in medical or biomedical research careers.

The sciences of ethology and sociobiology have as premisses that certain dispositions and behavioural patterns have evolved with species and, therefore, that the acts of individual animals and men must be viewed in light of innate determinates. These ideas are much older than the now burgeoning disciplines of the biology of behaviour. Their elements were fused in the early constructions of evolutionary theory, and they became integral parts of the developing conception. Historians, however, have usually neglected close examination of the (...) role behaviour has played in the rise of evolutionary thought. (shrink)

Our image of Herbert Spencer is that of a bald, dyspeptic bachelor, spending his days in rooming houses, and fussing about government interference with individual liberties. Beatrice Webb, who knew him as a girl and young woman recalls for us just this picture. In her diary for January 4, 1885, she writes: Royal Academy private view with Herbert Spencer. His criticisms on art dreary, all bound down by the “possible” if not probable. That poor old man would miss me on (...) the whole more than any other mortal. Has real anxiety for my welfare—physical and mental. Told him story of my stopping cart horse in Hyde Park and policeman refusing to come off his beat to hold it. Want of public spirit in passers-by not stopping it before. “Yes, that is another instance of my first principle of government. Directly you get state intervention you cease to have public spirit in individuals; that will be a constantly increasing tendency and the State, like the policeman, will be so bound by red-tape rules that it will frequently leave undone the simplest duties.”1 Spencer appears a man whose strangled emotions would yet cling to a woman whose philosophy would be completely alien to his own, as Webb’s Fabian Socialism turned out to be. Our image of Darwin is more complex than our image of Spencer. We might think of him nestled in the bosom of his large family, kindly, and just a little sad. The photo of him taken by Julia Cameron reveals the visage of an Old Testament prophet, though one, not fearsome, but made wise by contemplating the struggle of life on this earth. These images have deeply colored our reaction to the ideas of each thinker. The pictures are not false, but they are cropped portraits that tend to distort our reactions to the theories of each.

If religion means a commitment to a set of theological propositions regarding the nature of God, the soul, and an afterlife, Ernst Haeckel (1834-1919) was never a religious enthusiast. The influence of the great religious thinker Friedrich Daniel Schleiermacher (1768-1834) on his family kept religious observance decorous and commitment vague.2 The theologian had maintained that true religion lay deep in the heart, where the inner person experienced a feeling of absolute dependence. Dogmatic tenets, he argued, served merely as inadequate symbols (...) of this fundamental experience. Religious feeling, according to Schleiermacher’s Über die Religion (On religion, 1799), might best be cultivated by seeking after truth, experiencing beauty, and contemplating nature.3 Haeckel practiced this kind of Schleiermachian religion all of his life. Haeckel’s association with the Evangelical Church, even as a youth, had been conventional. The death of his first wife severed the loose threads still holding him to formal observance. The power of that death, his obsession with a life that might have been, and the dark feeling of love forever lost drove him to find a more enduring and rational sub-. (shrink)

Ernst Haeckel’s popular book Nat¨urliche Sch¨opfungs- geschichte (Natural history of creation, 1868) represents human species in a hierarchy, from lowest (Papuan and Hottentot) to highest (Caucasian, including the Indo-German and Semitic races). His stem-tree (see Figure 1) of human descent and the racial theories that accompany it have been the focus of several recent books—histories arguing that Haeckel had a unique position in the rise of Nazi biology during the first part of the 20th century. In 1971, Daniel Gasman brought (...) the initial bill of particulars; he portrayed Haeckel as having specific responsibility for Nazi racial programs. He argued that Darwin’s champion had a distinctive authority at the end of the 19th century, throwing into the shadows the myriads of others with similar racial attitudes.1 But it was not simply a general racism that Haeckel expressed; he was, according to Gasman (1971: 157–159), a virulent anti-Semite. Since its original publication, Gasman’s thesis has caught on with a large number of historians, so that in the present period it is usually taken as a truism, an obvious fact of the sordid history of biological thought in the first half of the 20th century.2 Perhaps the most prominent scholar—at least among historians of biology—to adopt and advance Gasman’s contention was Stephen Jay Gould. In his first book, Ontogeny and Phy- logeny (1977), Gould took as his subject Haeckel’s principle of recapitulation, the proposal that during ontogeny the developing embryo went through the same morphological stages as the phylum passed through in its evolutionary descent. So according to this conception, the human embryo begins as a one-celled creature, then takes on the form of an ancient invertebrate (e.g., a gastraea), then of a primitive vertebrate, then of an early mammal, then of a primate, and finally of a distinct..

Chapter III contains several puzzles and unexpected features. The first puzzle regards the chapter’s relationship to Chapter IV: Natural Selection. Both chapters treat of natural selection, so what distinguishes them? Is it that Chapter IV indicates the intelligence behind nature’s selections and Chapter III introduces the analog of intelligence? And is it that Chapter III suggests that natural selection performs an eliminative function, while Chapter IV shows the positive impact of selection? In Chapter IV, and in many subsequent chapters, natural (...) selection, Darwin says, operates only for the good of each individual creature, though Chapter III suggests it destroys most individuals. Darwin asserts that he uses the term “struggle” metaphorically, which raises the question of the explanatory weight his metaphors carry, such metaphors as "the face of nature.” There are a number of unexpected features of Darwin’s analysis displayed in the chapter: for example, his introduction of a new concept of the selective environment and the several experiments he performs to establish his theory, e.g., from mathematical and thought experiments to controlled empirical experiments. Chapter III is a rich though puzzling chapter. (shrink)

In 1914, James Leuba, a psychologist at Bryn Mawr, conducted several surveys of scientists and college students regarding their religious beliefs, publishing his findings in a 1916 book titled The Belief in God and Immortality. Among scientists generally, 41.8 percent indicated they were believers in a personal God (defined as a being to whom one could pray, expecting a response), whereas 41.5 percent expressed disbelief in such a God and 16.7 percent declared themselves to be agnostic. Among elite scientists (those (...) with an asterisk by their names in James McKean Cattell's American Men of Science), the percentage of believers was lower, at 31.6 percent. Among elite biologists, the subset who believed in God was even smaller—16.9 percent. In 1996 and 1998, Edward Larson and Larry Witham replicated Leuba's study, publishing their findings in the April 23, 1997, and July 23, 1998, issues of Nature. Their surveys revealed that of all scientists questioned, 39.3 percent professed belief in a personal God, about the same as in the 1914 study. However, among elite scientists—now defined as members of the National Academy of Sciences—the proportion who were believers had plummeted to 7 percent, with biologists showing the least religious conviction at 5.5 percent. In the general population of the United States, some 86 percent profess belief in the existence of a personal God, according to a 1999 Gallup poll. These figures dramatically indicate the great no-mans land separating the religious convictions of ordinary citizens from those of the scientific community, especially its leading members. This dissensus has fueled many of the bitter battles recently fought over evolution and stem cells and has ignited explosive devices laid along several political byways. (shrink)

Scholars have usually given Darwin’s theory a neo-Darwinian interpretation. A more careful examination of the language of Darwin’s notebooks and the language of the Origin of Species indicates that he reconstructed nature with a definite purpose: the final goal of man as a moral creature. In the aftermath of the Origin, Darwin, however, became more circumspect.

Historians, the good ones, mark a century by intellectual and social boundaries rather than by the turn of the calendar page. Only through fortuitous accident might occasions of consequence occur at the very beginning of a century. Imaginative historians do tend, however, to invest a date like 1800 with powers that attract events of significance. It is thus both fortunate and condign that Abiology@ came to linguistic and conceptual birth with the new century. Precisely in 1800, Karl Friedrich Burdach, a (...) romantic naturalist, suggested that his coinage Biologie be used to indicate the study of human beings from a morphological, physiological, and psychological perspective.i Many other neologisms of the period (and Burdach issued quite a few) were stillborn or survived only for a short while. Biologie, though, fit the time, and with slight adjustment received its modern meaning two years later at the hands of the Naturphilosoph Gottfried Reinhold Treviranus. In his multi-volume treatise Biologie, oder Philosophie der lebenden Natur (1802-1822), Treviranus announced: AThe objects of our research will be the different forms and manifestations of life, the conditions and laws under which these phenomena occur, and the causes through which they have been effected. The science that concerns itself with these objects we will indicate by the name biology [Biologie] or the doctrine of life [Lebenslehre].@ii Jean-Baptiste de Lamarck, also in 1802, employed the term with comparable intention.iii In the work of both of these biologists, the word became immediately associated with the theory of the transmutation of speciesCa new term in recognition of the new laws of life.

Through the last half of the nineteenth century and the first part of the twentieth, no scientist more vigorously defended Darwinian theory than the German Ernst Haeckel (1834–1919). More people learned of the new ideas through his voluminous publications, translated into numerous languages, than through any other source, including Darwin’s own writings. He enraged many of his contemporaries, especially among the religiously orthodox; and the enmity between evolutionary theory and religious fundamentalism that still burns brightly today may in large measure (...) be attributed to Haeckel’s unremitting attacks on the ingressions of religion into science. Though he retained a life-long friendship with and the support of Darwin, some in the scientific community who were critical of evolutionary theory—Emil Du Bois-Reymond, Rudolf Virchow, and Louis Agassiz, for instance—accused him of deception. That charge has been renewed in our time based on seemingly incontrovertible evidence. In a Science magazine article published in 1997, ‘‘Haeckel’s Embryos: Fraud Rediscovered,’’ Haeckel, was indicted of having intentionally misrepresented embryological development (Pennisi 1997). The article reported that the work of Michael Richardson and his colleagues demonstrated this malfeasance through a comparison of Haeckel’s illustrations of early-stage embryos with photographs of the same species at a comparable stage (see Fig. 1). The photos showed embryos of various species that differed among themselves and certainly from Haeckel’s images. The differences were striking and the implication obvious: fraudulent misrepresentation. Richardson, as quoted in the article, affirmed the charge: ‘‘It looks like it’s turning out to be one of the most famous fakes in biology’’. (shrink)

In 1853, two decades after Goethe’s death, Hermann von Helmholtz, who had just become professor of anatomy at Königsberg, delivered an evaluation of the poet=s contributions to science.1 The young Helmholtz lamented Goethe=s stubborn rejection of Newton =s prism experiments. Goethe=s theory of light and color simply broke on the rocks of his poetic genius. The tragedy, though, was not repeated in biological science. In Helmholtz=s estimation, Goethe had advanced in this area two singular and “uncommonly fruitful” ideas.2 The poet (...) recognized, first, that the anatomical structures of various kinds of animals revealed a unity type underlying the superficial differences arising from variability of food, habit, and locality. His second lasting achievement was the related theory of the metamorphosis of organisms: the thesis that the various articulations within an organism developed out of a more basic kind of structure—that, for instance, the different parts of plants were metamorphosed leaves or that the various bones of the animal skull were but transformed vertebrae. These two general morphological conceptions, according to Helmholtz, grounded the biology flourishing at 1 mid-century. Goethe came to these ideas, Helmholtz shrewdly maintained, as the result of a poetically intuitive conception.3 He described, for instance, Goethe=s immediate recognition, while playfully tossing around a sheep=s skull on the Lido in Venice, that the fused bones of the battered cranium consisted of transmuted vertebrae. This experience resulted in the poet=s vertebral theory of the skull, which became a standard conception in later morphology.4 Poetic intuition thus liberated an idea initially embedded in matter and made it available to the analytic understanding of the scientist. Forty years later, in 1892, at the meeting of the Goethe Society in Weimar, Helmholtz returned to reexamine the poet=s scientific accomplishments, and, it would seem, implicitly his own; for by the end of his career, Helmholtz himself had achieved a position in German culture only a few steps below that of Goethe.5 His evaluation of Goethe=s achievements in physical science was now more complex than his earlier assessment had been.
