우리는 이 논문에서 앙리 베르그손의 작품 『창조적 진화』의 두 원천을 조명해 보고자 한다. 저자가 이 책에서 전개하는 견해는 당대의 과학적 소여들에 대한 분석에 기초하고 있을 뿐 아니라 멘 드 비랑으로부터 라베쏭으로 이어지는 프랑스의 유심론적 흐름에 그 기원을 둔다. 프랑스 유심론이 의식의 고유한 체험을 강조한다면 과학적 인식은 외부 세계에 대한 관찰과 이에 대해 과학자들이 제시하는 설명으로 이루어진다. 이러한 근대과학에 대한 반성과 유심론적 전통의 대조가 『창조적 진화』의 어려움의 원인인 동시에 독창성을 제공한다. 오늘날 우리는 생물학과 물리학의 발달에서 새로운 경향들의 출현으로 인해 베르그손이 논박하고자 (...) 노력했던 기계론적 사유로부터 어느 정도 자유로울 수 있다. 따라서 우리는 이 책의 주된 두 가지 원천을 분석하면서 이를 토대로 베르그손이 거기서 구체화하는 독창적인 사유를 조명해 보고자 한다.

One way to understand science is as a selection process. David Hull, one of the dominant figures in contemporary philosophy of science, sets out in this 2001 volume a general analysis of this selection process that applies equally to biological evolution, the reaction of the immune system to antigens, operant learning, and social and conceptual change in science. Hull aims to distinguish between those characteristics that are contingent features of selection and those that are essential. Science and Selection brings together (...) many of David Hull's most important essays on selection in one accessible volume. (shrink)

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from (...) molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions. The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

In this chapter, I shall consider a number of connections between various ideas of the theory of styles of reasoning and the issue of the contingency and inevitability of science. By ‘contingency issue’ it is meant the question as to whether the history of a particular branch of our science could have taken a different route and provided results incompatible with those of our actual science. Apart from Hacking’s recent comments, the discussions on the contingency issue have not involved the (...) notion of style of reasoning. I will fill this gap in the literature by drawing some important implications for the issue of contingency from the theory of styles of reasoning that I have developed so far. I shall address four fundamental questions. First of all, in the next section I shall discuss to which extent the emergence of styles of reasoning at a certain point of history is a contingent circumstance. In the following section I shall ask whether the endurance of styles of reasoning was inevitable by tackling the connected question as to why the styles are long lasting. Afterwards, I shall focus on the growth of knowledge by dealing with questions such as: if a certain style of reasoning continues to be employed and if Q is a ‘live question’, is science bound to converge on a single answer to Q? Finally, on the basis of my previous reflections I shall look into the question of the convergence of science in the long run. The answers to these questions will rely on some basic assumptions of the theory of style of reasoning and imply a picture of the evolution of sciences in which both contingency and inevitability play a key role.

Materialists argue that there is no place for God in the universe. Chance and contingency are all that structure our world. However, the materialists’ dismissal of subjectivity manifests a flawed metaphysics that invalidates their arguments against God. In this essay I explore the following: (1) How does personal metaphysics affect one's ability to do science? (2) Are the materialist arguments about contingency used to dismiss the importance of our place in the universe valid? (3) What are the implications of subjectivity (...) on belief and science? To answer the first question, I examine the later years of Sir Alfred Russel Wallace, one of the cofounders of evolution through natural selection with Darwin. His belief in nineteenth–century spiritualism profoundly affected his standing in the scientific community. I describe the effect of spiritualism on Wallace's science. To answer the second question, I use my own work in mathematical modeling of evolutionary processes to show that randomness, and contingency at one level, can actually be nearly deterministic at another. I demonstrate how arguments about chance and contingency do not imply anything relevant about whether there is a designer behind the universe. To answer the third question I begin by exploring a paradox of consciousness and show how the existence of subjective truths may provide a paradigm for sustaining a rational belief in God. These questions form the framework of a structured belief in a creator while yet embracing what science has to offer about the development of life on our planet. (shrink)

The starting point for this article is the question of the relationship between Darwinism and Christian theology. I suggest that evolutionary theory presents three broad issues of relevance to theology: the phenomena ofcontinuity, naturalism, andcontingency. In order to formulate a theological response to these issues I draw on the semiotics (theory of signs) and cosmology of the American philosopher Charles Sanders Peirce. Peirce developed a triadic theory of signs, underpinned by a threefold system of metaphysical categories. I propose a semiotic (...) model of the Trinity based on Peirce's semiotics and categories. According to this model the sign‐processes (such as the genetic “code”) that are fundamental to life may be understood as vestiges of the Trinity in creation. I use the semiotic model to develop a theology of nature that addresses the issues raised by evolutionary theory. The semiotic model amounts to a proposal for a new metaphysical framework within which to understand the relationship between God and creation and between theology and science. (shrink)

Since Darwin, the idea of psychological continuity between humans and other animals has dominated theory and research in investigating the minds of other species. Indeed, the field of comparative psychology was founded on two assumptions. First, it was assumed that introspection could provide humans with reliable knowledge about the causal connection between specific mental states and specific behaviors. Second, it was assumed that in those cases in which other species exhibited behaviors similar to our own, similar psychological causes were at (...) work. In this paper. we show how this argument by analogy is flowed with respect to the case of second-order mental states. As a test case, we focus on the question of how other species conceive of visual attention, and in particular whether chimpanzees interpret seeing as a mentalistic event involving internal states of perception, attention, and belief. We conclude that chimpanzees do not reason about seeing in this manner, and indeed, there is considerable reason to suppose that they do not harbor representations of mental states in general. We propose a reinterpretation model in which the majority of the rich social behaviors that humans and other primates share in common emerged long before the human lineage evolved the psychological means of interpreting those behaviors in mentalistic terms. Although humans, chimpanzees, and most other species may be said to possess mental states, humans alone may have evolved a cognitive specialization for reasoning about such states. (shrink)

This paper addresses the relation between the intelligible and the material world in the works of the Neoplatonic philosopher Damascius (ca. 460-ca. 538 AD), who uses the theory of the Platonic Ideas in order to discuss the evolution from the One to the Manifold. This relation arises through specific laws that lead to the development of a harmonious cosmic system. The vertical and the horizontal segmentation of metaphysical causes is implemented in the process of the generation of the empirical world, (...) which is nevertheless imperfect in the sense that it is an image of the metaphysical world and is subject to generation and decay. The metaphysical world constitutes a normative basis for the beings of the world of experience to the same extent in the ontological as in the aesthetic and ethical area. The vertical segmentation cannot be understood without the horizontal because in that case the generation of tangible beings, which are complex realities, would be implausible. At the same time, the horizontal segmentation without the vertical would result in inactive metaphysical causes. The simple fact that the empirical world exists excludes such alternatives. (shrink)

Certains commentateurs de Bergson ont estimé que sa pensée était d'emblée spiritualiste et teintée de religiosité. On peut comprendre ainsi le beau texte de Louis Lavelle, "La pensée religieuse d'Henri Bergson", ou l'interprétation que Péguy fait de cette philosophie rationaliste du temps. Cette compréhension de Bergson peut d'ailleurs s'appuyer sur un texte du philosophe lui-même, à savoir Principes de métaphysique et de psychologie où Bergson explique que sa pensée vise à constituer une "science relative de l'absolu". Le présent volume tente (...) d'examiner dans quelle mesure il est possible de soutenir, l'instar d'Henri Gouhier, que l'oeuvre d'observation intérieure de Bergson a posé les bases du spiritualisme moderne.

The contingency of biological regularities—and its implications for the existence of biological laws—has long puzzled biologists and philosophers. The best argument for the contingency of biological regularities is John Beatty’s evolutionary contingency thesis, which will be re-analyzed here. First, I argue that in Beatty’s thesis there are two versions of strong contingency used as arguments against biological laws that have gone unnoticed by his commentators. Second, Beatty’s two different versions of strong contingency are analyzed in terms of two different stabilities (...) of regularities. Third, I argue that Beatty and his commentators have focused on the more ineffective trajectory stability version of the argument, whereas the constancy stability version provides a more substantial and applicable argument against the existence of biological laws. Fourth, I develop a counterexample to Beatty’s thesis. Finally, I discuss the possibility of evolution producing repeatable and general non-lawlike regularities and patterns by utilizing the notion of generative entrenchment and by criticizing the thesis of multiple realizability of biological properties.

The nineteenth century theologian, author and poet Charles Kingsley was a notable populariser of Darwinian evolution. He championed Darwin’s cause and that of honesty in science for more than a decade from 1859 to 1871. Kingsley’s interpretation of evolution shaped his theology, his politics and his views on race. The relationship between men and apes set the context for Kingsley’s consideration of these issues. Having defended Darwin for a decade in 1871 Kingsley was dismayed to read Darwin’s account of the (...) evolution of morals in Descent of Man. He subsequently distanced himself from Darwin’s conclusions even though he remained an ardent evolutionist until his death in 1875. (shrink)

Stephen Jay Gould argued that replaying the ‘tape of life’ would result in radically different evolutionary outcomes. Recently, biologists and philosophers of science have paid increasing attention to the theoretical importance of convergent evolution—the independent origination of similar biological forms and functions—which many interpret as evidence against Gould’s thesis. In this paper, we examine the evidentiary relevance of convergent evolution for the radical contingency debate. We show that under the right conditions, episodes of convergent evolution can constitute valid natural experiments (...) that support inferences regarding the deep counterfactual stability of macroevolutionary outcomes. However, we argue that proponents of convergence have problematically lumped causally heterogeneous phenomena into a single evidentiary basket, in effect treating all convergent events as if they are of equivalent theoretical import. As a result, the ‘critique from convergent evolution’ fails to engage with key claims of the radical contingency thesis. To remedy this, we develop ways to break down the heterogeneous set of convergent events based on the nature of the generalizations they support. Adopting this more nuanced approach to convergent evolution allows us to differentiate iterated evolutionary outcomes that are probably common among alternative evolutionary histories and subject to law-like generalizations, from those that do little to undermine and may even support, the Gouldian view of life.

Recently, philosophers have sought to determine the nature of individuals relevant to evolution by natural selection or evolutionary individuals. The Evolutionary Contingency Thesis is a claim about evolution that emphasizes the role of contingency or dependency relations and chance-based factors in how evolution unfolds. In this article, I argue that if we take evolutionary contingency seriously, then we should be pluralists about the types of individuals in selection.

This paper is an overview of the philosophy of evolution – past, present, and future. It surveys the following topics: the neutralist/selectionist debate, the adapationist programme and its challenges, sociobiology, contingency, laws of biology, the species category problem, the species taxon problem, the tautology problem, fitness, units of selection.

Dès 1903, L'évolution de la mécanique signala, à l'attention du public, Pierre Duhem en tant que philosophe et historien des sciences. Le terme de mécanique étant pris dans son extension la plus large, l'auteur y retrace, dans un langage limpide, les transformations qui ont affecté la physique dans son ensemble. A partir d'une analyse attentive de la crise que traversait alors la science, Duhem formule plusieurs thèses profondes et originales, qui amèneront la conception générale de son ¶uvre célèbre, La théorie (...) physique. Cette édition a été augmentée de deux articles complémentaires. Une seule fois, Duhem s'est penché en historien sur la thermodynamique, son principal champ de recherche scientifique ; " Les théories de la chaleur " expliquent ses choix philosophiques. L'" Analyse de l'ouvrage de Ernst Mach : La Mécanique " témoigne d'une entente inattendue entre le savant-philosophe français et son homologue autrichien. (shrink)

Stephen Jay Gould argued that replaying the “tape of life” would result in a radically different evolutionary outcome. Some biologists and philosophers, however, have pointed to convergent evolution as evidence for robust replicability in macroevolution. These authors interpret homoplasy, or the independent origination of similar biological forms, as evidence for the power of natural selection to guide form toward certain morphological attractors, notwithstanding the diversionary tendencies of drift and the constraints of phylogenetic inertia. In this paper, I consider the implications (...) of homoplasy for the debate over the nature of macroevolution. I argue that once the concepts of contingency and convergence are fleshed out, it becomes clear that many instances of homoplasy fail to negate Gould’s overarching thesis, and may in fact support a Gouldian view of life. My argument rests on the distinction between parallelism and convergence, which I defend against a recent challenge from developmental biology. I conclude that despite the difficulties in defining and identifying parallelism, the concept remains useful and relevant to the contingency controversy insofar as it underscores the common developmental origins of iterated evolution.

This article reviews, and offers supportive reflections on, the main points of Ernan McMullin's provocative 1998 article, “Cosmic Purpose and the Contingency of Human Evolution,’’ reprinted in this issue of Zygon. In it he addresses the important science-theology issue of how the Creator's purpose and intention to assure the emergence of human beings is consonant with the radical contingency of the evolutionary process. After discussing cosmic and biological evolution and critically summarizing recent solutions to this question by Keith Ward, John (...) Polkinghorne, Arthur Peacocke, Alvin Plantinga, and others, who presuppose in different ways that God is subject to time, McMullin compellingly argues for the traditional position, that God is unconditioned by time, and this enables God to work purposefully through contingency, randomness, and chance just as easily as through law-like regularity.

This essay moves along broad lines from molecular biology to evolutionary biology and ecology to theology. Its objectives are to: 1) present some recent scientific findings in the emerging field of epigenetics that indicate that it is “the genome in context,” not genes per se, that are important in biological development and evolution; 2) show that this weakens the gene-centric neo-Darwinist explanation of evolution which, in fact, shares a certain preformationist orientation with intelligent design theory; 3) argue that the evidence (...) against a gene-centric view in no way negates Darwin’s central idea of “descent with modification”; 4) argue that an embrace of the evolutionary story, with all of its contingency and apparent lack of directionality, is not only consistent with Christianity, but actually resonates with the notion of the self-emptying love of God in Jesus Christ; and finally 5) suggest that we are called through an ecological imperative to embrace our evolutionary story, to listen to our “genetic coding,” and to reclaim our grounding as a species in the natural world. Corrigendum (published in later issue of journal): There was an error in the paragraph describing the mode of action of the small temporally-expressed RNAs (stRNAs) lin-4 and let-7 from Caenorhabditis elegans. Instead of reading "These two stRNAs act by binding to the tails of their target messenger RNAs (mRNAs); this results in destruction of the target and an overall drop in the level of production of protein from agouti mRNA" [note that agouti mRNA is not a target of these stRNAs], the sentence should have read, "These two stRNAs act by binding to the tails of target messenger RNAs (mRNAs); this leads to inhibition of translation of the mRNAs into protein and a consequent drop in the levels of the corresponding target protein.".

Evolutionary biology since Darwin has seen a dramatic entrenchment and elaboration of the role of chance in evolution. It is nearly impossible to discuss contemporary evolutionary theory in any depth at all without making reference to at least some concept of “chance” or “randomness.” Many processes are described as chancy, outcomes are characterized as random, and many evolutionary phenomena are thought to be best described by stochastic or probabilistic models. Chance is taken by various authors to be central to the (...) understanding of fitness, genetic drift, macroevolution, mutation, foraging theory, and environmental variation, to take but a few examples. And for each of these notions, there are yet more stories to tell. Each weaves itself into the various branches of evolutionary theory in myriad different ways, with a wide variety of effects on the history and current state of life on Earth. Each is grounded in a particular trajectory in the history of philosophy and the history of biology, and has inspired a variety of responses throughout science and culture. This book endeavors to offer a cross-section of biological, historical, philosophical, and theological approaches to understanding chance in evolutionary theory. (shrink)

The normalized, deterministic conception of evolution espoused by Dennett is increasingly being challenged by theorists who, following Gould, emphasize the role that historical contingencies play in it. I explore the conflict between these views and argue that correcting our understanding of the relationship between nature’s systematic necessities and historical temporality can resolve it. The mathematically precise laws science formulates describe the systematic patterns of nature abstractly and, as abstractions, these laws do not preclude but allow for the contingencies of historical (...) time. Drawing on Heidegger and Hume, I argue that historical time is characterized by the ingression of the unprecedented future into the present. This is the ontological infrastructure that makes the evolution of unprecedented ontological alterities possible. (shrink)

Lawton’s contingency thesis states that there are no useful generalizations at the level of ecological communities because these systems are especially prone to contingent historical events. I argue that this influential thesis has been grounded on the wrong kind of evidence. CT is best understood in Woodward’s terms as a claim about the instability of certain causal dependencies across different background conditions. A recent distinction between evolution and ecology reveals what an adequate test of Lawton’s thesis would look like. To (...) date, CT remains untested. But developments in genome and molecular ecology point in a promising direction. (shrink)

The idea of an inevitable conflict between science and religion was decisively challenged by John Hedley Brooke in his classic Science and Religion: Some Historical Perspectives. Almost two decades on, Science and Religion: New Historical Perspectives revisits this argument and asks how historians can now impose order on the complex and contingent histories of religious engagements with science. Bringing together leading scholars, this volume explores the history and changing meanings of the categories 'science' and 'religion'; the role of publishing and (...) education in forging and spreading ideas; the connection between knowledge, power and intellectual imperialism; and the reasons for the confrontation between evolution and creationism among American Christians and in the Islamic world. A major contribution to the historiography of science and religion, this book makes the most recent scholarship on this much misunderstood debate widely accessible. (shrink)

Creation and evolution were historic allies against eternalism. However, Darwinism seemed to undercut cosmological theism and human dignity, and modern reconcilers of evolution and theology have not convinced opponents that they can preserve these concerns. Creationists find divine handiwork in natural order and freedom in human uniqueness. For them, even entropy and continuity of kinds are emblematic of the unity of nature and the needfulness of salvation. Anti‐evolutionists’ impatience and frustration are not well answered by dogmatic or mythicized science. Neither (...) is creation well served by reduction to merely empiric facts. Because creationism and evolutionism rest on the unabstractable categories of contingency and necessity, neither will disappear. (shrink)

The placenta arose during mammalian evolution, which is recent in evolutionary terms. Genetic changes underlying placental development remain identifiable by the new science of comparative genomics (approximately post‐2000). Randomly arising features of genomes including endogenous retroviruses and transposable elements have provided structural genes and gene‐regulatory motifs responsible for innovations in placental biology. Stochastic genetic events indeed contribute to new functionality. Theologically, random mutations are part of the strategy by which the divine purpose for humanity is attained. Placental function critically underlies (...) human brain development, and suboptimal function, associated with environmental conditions and maternal distress, contributes to mental health deficits in the offspring. Many enter life with handicaps arising from contingent events in utero, mandating understanding, compassion, and socioemotional support, imperatives native to moral including biblical values. The extended period of development afforded by placentation enables prenatal parenting, with implications for sensitive and devoted parental commitment. (shrink)

Peut-on établir un parallèle entre les sciences de la nature et les sciences humaines comme l'économie? La tentative est hardie et le résultat n'est pas garanti, car les unes et les autres n'appartiennent pas au même système de pensée. En outre, certains économistes ont voulu importer dans leur discipline des concepts nés dans le domaine des sciences dites "exactes", de façon à leur donner une connotation plus scientifique. Ce fut un échec. Malgré tout, les immenses progrès réalisés depuis le début (...) du XXe siècle, d'abord en physique, puis en biologie et enfin en neurosciences, ont eu un tel impact sur notre univers mental et sur notre manière de concevoir le monde que les sciences humaines ne pouvaient pas en sortir indemnes. Des notions aussi fondamentales que le temps, l'espace, la vie, la pensée, l'ordre, l'évolution, l'équilibre ne peuvent plus désormais être conçues comme elles l'étaient auparavant, et l'économie, de même que les autres sciences humaines, en a été profondément transformée. Il restera malgré tout une différence irréductible entre les sciences de la nature et les sciences humaines, car - Descartes l'avait déjà dit - la conscience de l'être humain, sa pensée, demeure rebelle à toute tentative de formalisation.

Determining whether a homoplastic trait is the result of convergence or parallelism is central to many of the most important contemporary discussions in biology and philosophy: the relation between evolution and development, the importance of constraints on variation, and the role of contingency in evolution. In this article, I show that two recent attempts to draw a black-or-white distinction between convergence and parallelism fail, albeit for different reasons. Nevertheless, I argue that we should not be afraid of gray areas: a (...) clarified version of S. J. Gould's earlier account, based on a separation of underlying developmental mechanisms from the realized trait, still represents a useful approach. (shrink)

Discussions of reproducibility are casting doubts on the credibility of experimental outcomes in the life sciences. Although experimental evolution is not typically included in these discussions, this field is also subject to low reproducibility, partly because of the inherent contingencies affecting the evolutionary process. A received view in experimental studies more generally is that standardization (i.e., rigorous homogenization of experimental conditions) is a solution to some issues of significance and internal validity. However, this solution hides several difficulties, including a reduction (...) of external validity and reproducibility. After explaining the meaning of these two notions in the context of experimental evolution, we import from the fields of animal research and ecology and suggests that systematic heterogenization of experimental factors could prove a promising alternative. We also incorporate into our analysis some philosophical reflections on the nature and diversity of research objectives in experimental evolution. (shrink)

On propose quelques réflexions sur le concept de temps, tout d'abord rappelant la diversité des expériences et des consciences du temps, et montrant comment le temps des sciences et de la physique est relié à cette expérience et à cette conscience qui en est prise, notamment en ce qui concerne le rapport entre l'instant et la durée. On s'efforce ensuite de tirer deux leçons des développements sur le concept de temps tel qu'il se présente en physique. La première est que (...) le concept de temps est construitpar la pensée, et ne nous est pas directement donné, soit par la nature, soit par notre «sens interne». Cela apparait, notamment, avec l'introduction du temps comme paramètre de la dynamique par Galilée, puis avec la définition du temps «absolu et mathématique » par Newton en vue de constituer le «temps instantané» de la loi fondamentale de la mécanique, et enfin avec la critique des limites de cette conception qui aboutit à la formulation de la relativité du temps et de son lien de constitution à l'espace (construction de l'espace-temps). La seconde leçon est que le temps se définit et se détermine par les phénomènes(et les objets) de la nature (qui se ramènent aux propriétés de la matière), alors qu'on a longtemps cru l'inverse. Cela apparait notamment avec la soumission du temps, dans la reconstruction du concept effectuée par Einstein, d'abord à des principes physiques(avec la relativité restreinte), ensuite avec sa détermination, conjointement à l'espace (dans l'espace-temps), par les champs de gravitation, qui sont des propriétés de la matière. Ce caractère est également confirmé par la deuxième loi de la thermodynamique et par les développements récents de la cosmologie. (shrink)

Ignace Meyerson (1888-1983), juif polonais naturalise francais a 35 ans, medecin, licencie en sciences et en philosophie, est le fondateur de la psychologie historique et comparative. Prenant pour objet d'enquete tout ce que les hommes ont produit, conserve et transmis, il affirme que la variation de ces oeuvres dans l'espace et dans le temps suppose que l'esprit humain soit lui-meme le lieu d'une histoire. La methode de Meyerson consiste a construire, a partir des faits de civilisation documentes par les sciences (...) humaines, la genealogie des fonctions psychologiques - poles de l'activite mentale tels que la memoire, la perception de la couleur ou la personne elle-meme - et a montrer ainsi leur evolution et leur contingence. En etendant ce programme aux civilisations anciennes, Jean-Pierre Vernant et Marinette Dambuyant, disciples de Meyerson, ont confirme la pertinence de cette approche genetique et comparatiste. Refusant l'abstraction philosophique, le determinisme sociologique ou l'analyse structurale, la psychologie historique a ete l'une des voies du renouvellement des sciences humaines. Son originalite est d'accorder au registre psychologique autant le role de moteur que de matiere dans la transformation de l'experience humaine. (shrink)

Après trente ans de suppression, le rétablissement de la sociologie en Chine au début des années 1980 et son développement jusqu’à aujourd’hui offrent un cas critique d’analyse des conditions politiques, sociales et intellectuelles d’existence de la discipline. Comment cette science supprimée, violemment critiquée puis réhabilitée par le régime communiste se reconstruit-elle ? L’article présente le processus de reconstitution de la discipline, en mettant en lumière les formes d’engagement des différentes générations de chercheurs, les ressources qu’ils mobilisent ainsi que les débats (...) qu’ils soulèvent. Il analyse ensuite les productions sociologiques et leurs évolutions à partir de deux perspectives,les transformations de la société chinoise et la question de la modernisation.After being banned for thirty years, sociology has been allowed again in China in the early 80s, and its development to date provides a critical case for the study of the political, social and intellectual conditions essential for the existence of the discipline.

The article first describes the discipline’s reconstitution process, focusing on the commitment patterns of different generations of sociologists, on the resources they mobilize, as well as on the debates they raise. The sociological productions and their evolutions are eventually analysed through two perspectives, the transformations of the Chinese society and the issue of modernization. (shrink)

La période est à la transgression. Transgresser est en effet la nécessité même de l'ordre. Tel est le principe de base de tout pouvoir dès lors qu'il se proclame souverain. Autrement dit, il n'est de pouvoir que transgresseur. Telle est aussi l'énigme de la puissance attribuée à l'État depuis son élaboration principielle par Jean Bodin jusqu'aux énoncés de Carl Schmitt dont la formule "est souverain celui qui décide de la situation exceptionnelle", a permis au XXe siècle de donner un autre (...) contenu, dictatorial, à la question de la souveraineté. L'évolution récente de cette notion prise au piège de la fondation des grands ensembles plurinationaux telle l'Union européenne, réactualise la question de l'adéquation de la souveraineté avec la nation. C'est dans cette logique qu'une archéologie de cette notion paraît indispensable pour évaluer sa double évolution dont la première, transcendante et de type vertical, la fait descendre de la toute-puissance divine jusqu'à son incarnation populaire à travers ses séquences ecclésiales (le souverain pontife), royales, nationales et populaires. Une seconde évolution à partir de la Révolution française, que l'on peut qualifier d'horizontale, l'instaure sur le versant de son incarnation imaginée au sein de la nation, souveraineté nationale, ou au plan de l'universalité des citoyens, souveraineté populaire. Qu'elle soit fondée sur une représentation imaginée collective de soi, la nation, ou sur une identité citoyenne étendue à tous, le peuple, la question de la souverainetén'est soluble que dans cette double identité, nationale et populaire à travers la question de la démocratie qui apparaît ici fondamentale pour restituer au souverain-peuple la légitimité des choix qu'il opère au travers de la délégation de ses compétences aux représentants qu'il se donne. En fin de compte, la souveraineté est avant tout toute-puissante, et ainsi, il n'y a de puissance politique que découlant d'elle. (shrink)

This study concerns the ideas of one particular philosopher, Henri Bergson, whose views of time, intuition, and creativity have had a significant impact on art, literature, and the humanities, both in his time and in our own. Although it is generally recognized that Bergson's ideas have significantly impacted the arts and the humanities, it has not been recognized how they have also had a creative influence on the sciences as well. Nor has it been realized that this was one of (...) his most basic contentions. Bergson's conception of intuition--his fundamental insight into reality--was not limited to fugitive insights into human existence. By realizing previously unsuspected possibilities for research and discovery, his endeavors were also meant to make possible new advances in the sciences. If it enabled his cousin by marriage, Marcel Proust, to explore human memory in depth, it also inspired psychologists like Daniel Schachter to use Bergson's ideas to make real contributions to contemporary memory science. If his notion of creative evolution brought many thinkers to a belief in human creative freedom, it brought others (notably Alexis Carrel and Pierre Lecomte de Noüy) to a scientific study of biological time. Among his successful speculations was the theory of the Big Bang cosmology. 'Getting Bergson Straight' shows many points at which Bergson's ideas anticipated future developments in the sciences. This was seen clearly by the Nobel Prize-winning physicist Luis de Broglie who viewed Bergson's physics as presaging quantum physics. Thus, the text is well situated for arts, humanities, social science, and natural science classrooms studying creative thinking and/or intellectual history. (shrink)

RésuméDepuis les débuts de l'humanité, l'être humain s'est préoccupé de conserver les aliments en vue de les rendre plus longtemps comestibles. Au fil du temps, différentes méthodes pour préserver la nourriture ont été découvertes et perfectionnées, et ces techniques se trouvent décrites dans beaucoup d'œuvres. Ce travail décrit la connaissance des techniques de conservation qu'avaient les habitants de la péninsule ibérique ainsi que les développements qu'ils leur ont apportés. Il s'attache à étudier les divers procédés mis au point entre leieret (...) lexviesiècle, de façon à évaluer leur apport historique respectif. Les œuvres choisies et consultées sont : L.J.M.

The reflection on the preconditions and evolution of science has played a decisive role in the development of Ernst Cassirer's philosophy, contributing to its functional and thus inherently pluralistic and holistic view of knowledge. To present Cassirer's conception of physics as an open symbolic formation enables us to reveal and study the radical features of his epistemological model: (1) the fundamental process of generating sense-units and meaning in its constitutive character for each attempt of objectification, (2) its driving and structuring (...) dynamics that touches and transforms all elements of knowledge, the a priori included, (3) the strategies of justification that allow maintaining the claim of truthfulness in spite the fact that Cassirer's open model integrates contingency and transitoriness as an inherent part of knowledge. It thus becomes clear that Cassirer's term 'symbol' cannot be reduced to its habitual representational acceptation, for its key theoretical function is to overcome the inconsistencies of dualistic epistemological models. It is this re-orientation, a kind of 'second Copernican revolution', that allows Cassirer to go beyond traditional dichotomies and to propose a larger frame in which to appreciate the diversity of human understanding.

In this paper, I analyze George Gaylord Simpson's response to the molecularization of evolutionary biology from his unique perspective as a paleontologist. I do so by exploring his views on early attempts to reconstruct phylogenetic relationships among primates using molecular data. Particular attention is paid to Simpson's role in the evolutionary synthesis of the 1930s and 1940s, as well as his concerns about the rise of molecular biology as a powerful discipline and world-view in the 1960s. I argue that Simpson's (...) belief in the supremacy of natural selection as the primary driving force of evolution, as well as his view that biology was a historical science that seeks ultimate causes and highlights contingency, prevented him from acknowledging that the study of molecular evolution was an inherently valuable part of the life sciences.

What is it for history to matter? Stephen Gould argued that unpredictability is part of the answer. For example, the “fact“ that repeated replays of the history of life would end differently every time is a sign that history matters to the course of evolution. But there is a problem here: if a particular point in the past leaves open alternative possible futures, then in what sense does that point in the past matter with regard to which of the outcomes (...) occurs? We argue that unpredictability is central to the importance of history. However, it is not the unpredictability of the future, but rather the unpredictability of the past itself that is the key. History matters when a particular future depends on a particular past that was not bound to happen, but did. (shrink)

In contrast to Christian theology that has ignored science, this essay suggests that a credible doctrine of God as creator must take into account scientific understandings of the world. The introduction of the principle of inertia into seventeenth‐century science and philosophy helped change the traditional idea of God as creator (which included divine conservation and governance) into a deist concept of God. To recapture the idea that God continually creates, it is important to affirm the contingency of the world as (...) a whole and of all events in the world. Reflecting on the interrelationship of contingency and natural law provides a framework for relating scientific theories of a universal field, the concept of emergent evolution, and the theological concept of eternal divine spirit active in all creation.

In recent years there has been a renewed interest in the design argument, which states that the seemingly purposeful features of the natural world point to the existence of a supernatural designer. The purpose of this article is to give a brief survey of the fine-tuning of the fundamental constants in physics and cosmology, and complexity in biology, and their potential implications for the design argument. Contingency in the history of the earth and the evolution of life on earth is (...) also discussed, and some of the problems associated with inferring design from scientific investigations of nature are evaluated. It is concluded that an unambiguous detection of design in nature is not possible, but that this does not eliminate the demand for an ultimate explanation of the existence of the universe and the life it harbours.

This paper argues that besides mechanistic explanations, there is a kind of explanation that relies upon “topological” properties of systems in order to derive the explanandum as a consequence, and which does not consider mechanisms or causal processes. I first investigate topological explanations in the case of ecological research on the stability of ecosystems. Then I contrast them with mechanistic explanations, thereby distinguishing the kind of realization they involve from the realization relations entailed by mechanistic explanations, and explain how both (...) kinds of explanations may be articulated in practice. The second section, expanding on the case of ecological stability, considers the phenomenon of robustness at all levels of the biological hierarchy in order to show that topological explanations are indeed pervasive there. Reasons are suggested for this, in which “neutral network” explanations are singled out as a form of topological explanation that spans across many levels. Finally, I appeal to the distinction of explanatory regimes to cast light on a controversy in philosophy of biology, the issue of contingence in evolution, which is shown to essentially involve issues about realization.
