The thirteen original essays in this book examine the status and development of the sciences in the eighteenth century. The last generation has seen a revolution in the methodology adopted by historians of science: The development of science is no longer described as a steady progress towards truth - certainties have given way to questions. The essays in this volume scrutinize these changing perspectives in historiography and recommend paths for future study. The eighteenth century has been a neglected and much-misunderstood (...) era in the development of science, all too often viewed as something of a trough between the towering achievements of the 'Scientific Revolution' and the nineteenth century. Yet it was a period of notable developments; it saw the establishment of such fields as electricity and heat, the 'chemical revolution', the new science of gases, the isolation of oxygen, the nebular hypothesis in cosmology, the foundation of rational mechanics, and the birth pangs of biology, geology and psychology. It was, indeed, an age when knowledge was in ferment. (shrink)

Sequential action makes up the bulk of human daily activity, and yet much remains unknown about how people learn such actions. In one motor learning paradigm, the serial reaction time (SRT) task, people are taught a consistent sequence of button presses by cueing them with the next target response. However, the SRT task only records keypress response times to a cued target, and thus it cannot reveal the full time‐course of motion, including predictive movements. This paper describes a mouse movement (...) trajectory SRT task in which the cursor must be moved to a cued location. We replicated keypress SRT results, but also found that predictive movement—before the next cue appears—increased during the experiment. Moreover, trajectory analyses revealed that people developed a centering strategy under uncertainty. In a second experiment, we made prediction explicit, no longer cueing targets. Thus, participants had to explore the response alternatives and learn via reinforcement, receiving rewards and penalties for correct and incorrect actions, respectively. Participants were not told whether the sequence of stimuli was deterministic, nor if it would repeat, nor how long it was. Given the difficulty of the task, it is unsurprising that some learners performed poorly. However, many learners performed remarkably well, and some acquired the full 10‐item sequence within 10 repetitions. Comparing the high‐ and low‐performers’ detailed results in this reinforcement learning (RL) task with the first experiment's cued trajectory SRT task, we found similarities between the two tasks, suggesting that the effects in Experiment 1 are due to predictive, rather than reactive processes. Finally, we found that two standard model‐free reinforcement learning models fit the high‐performing participants, while the four low‐performing participants provide better fit with a simple negative recency bias model.

En opposant comme deux substances irréductibles l’âme et le corps, Descartes n’explique pas l’unité qui est en l’homme. En décrivant l’effort comme une réalité intermédiaire entre le corps et l’âme, Maine de Biran ressaisit l’individualité même. Devant le mystère humain, il faut donc invoquer l’expérience biranienne et non la métaphysique cartésienne : il convient d’appréhender, avant toute analyse, l’unité d’un élan, qui se disperse peut-être, mais garde sa souplesse.

La derni re dition des Lettres sur les animaux, ouvrage de l'encyclop diste mineur Charles-George Le Roy, date de 1896. Cette nouvelle dition propose une pr sentation tr s respecteuse de la pens e originale de l'auteur, elle pr cise dans quelles circonstances les divers l ments du livre furent successivement publi s et retrace son volution depuis les articles HOMME (Morale) et INSTINCT de l'Encyclop die jusqu' l' dition compl te de 1802. L'introduction situe les Lettresdans l'uvre de (...) Le Roy qui, comptant l' criture parmi ses activit s, fut d'autant plus m l aux conflits d'id es de l' poque. Des documents in dits permettent d' tablir avec exactitude combien Le Roy a su mettre profit ses fonctions de lieutenant des chasses des Parcs de Versailles pour exercer ses talents d'auteur. A la lumi re de divers autres documents, et parmi eux des in dits, il appara t que Le Roy fr quentait quelques-uns des penseurs les plus connus de l' poque (Condillac, Buffon, Diderot, Helv tius, d'Holbach), ainsi que des personnalit s de la haute soci t (en particulier Mme de Marchais), deux mondes don't l'influence est perceptible dans les Lettres sur les animaux. Celles-ci font cho non seulement aux crivains que leur auteur connaissit personnellement, mais aussi aux nombreux autres qu'il avait lus, notamment Montesquieu, Voltaire, Rousseau. Inspir et nourri de ces contacts scientifiques, litt raires et philosophiques, Le Roy a su s'en d gager pour d velopper sa propre pens e et, l'image de l'excellent accueil que les contemporains et la post rit ont r serv l'ouvrage, ses id es ne peuvent qu' veiller un vif int r t.

Do traits evolve because they are good for the group, or do they evolve because they are good for the individual organisms that have them? The question is whether groups, rather than individual organisms, are ever “units of selection.” My exposition begins with the 1960’s, when the idea that traits evolve because they are good for the group was criticized, not just for being factually mistaken, but for embodying a kind of confused thinking that is fundamentally at odds with the (...) logic that Darwin’s theory requires. A counter-movement has arisen since the 1960’s, called multi-level selection theory, according to which selection acts at multiple levels, including the level of the group. After discussing the 1960’s attack on group selection and the concept’s subsequent revival, I examine Darwin’s views on the subject. I discuss what Darwin says about four examples: human morality, the barbed stinger of the honeybee, neuter workers in species of social insect, and the sterility of many interspecies hybrids. I argue that Darwin defended hypotheses of group selection in the first three problems, but rejected it in the fourth. I also discuss Darwin’s general views about the role of group selection in evolution. (shrink)

‘There are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns—the ones we don’t know we don’t know.’ —Donald Rumsfeld, 2003, President George W. Bush’s Secretary of Defense, on the subject of the U.S. government’s failure to discover weapons of mass destruction in Iraq.

For Plato and Aristotle, arete (traditionally translated as "virtue") was the essential object of human admiration and striving, and even the key to happiness. Their work continues to inspire reflection on fundamental questions of ethics and politics today, as the fourteen new essays collected here demonstrate. -/- Contributors: Lidia Palumbo, Eva Anagnostou-Laoutides, Ryan M.

First thoughts about classification inevitably turn to the simultaneously mundane and extraordinary ambition to capture the universe of all that there is and has been. This dream of the universal has two basic modes (and so the process begins!). First, I will follow the spirit of theos and logos as represented by the Platonic embrace of totality enshrined in Socrates’ scrupulous rejection of rhetorical dishonesty. Second, I will address the later part of the march to subjectivity as expressed by the (...) mechanics of atomism and Cartesian reduction. Following this move from theology to ontology, from in other words the post-synthetic to the post-analytic, I will connect with the sociological destruction of such pretensions to absolute classificatory veracity – a necessary pre-requisite for the engagement of reflexivity and classification to be found in the work of Georges Perec.
