The complexity of the physiological phenotype currently prevents us from identifying an integrative measure to assess how the internal state and environmental conditions modify life‐history strategies. In this article, it is proposed that shorter telomeres should lead to a faster pace‐of‐life where investment in self‐maintenance is decreased as a means of saving energy for reproduction, but at the cost of somatic durability. Inversely, longer telomeres would favor an increased investment in soma maintenance and thus a longer reproductive lifespan (i.e., slower (...) pace‐of‐life). Under this hypothesis, telomere dynamics could be such an integrative mediator, which will assemble the information about oxidative stress levels, inflammation status and stress reactivity, and relate this information to the potential lifespan of the organism and its pace‐of‐life strategy. The signaling function of telomere dynamics can also reach over generations, a phenomenon in which the telomere lengths of gametes would provide a channel through which offspring would receive information about their environment early in their development, hence increasing the possibilities for developmental plasticity. -/- .

In a letter to theologian Thomas Burnet in the early 1680s, Newton suggests a chymical interpretation of the Mosaic account of Creation. He postulates that the System of the World, the Sun, the Earth and its landforms were formed through a succession of separations and coagulations from a “common Chaos”. The seas and the mountains resulted from the irregular coagulation of the parcel of Chaos assigned to our planet, in the same way as a saltpeter solution coagulates. All the transformations (...) of the primeval Chaos are performed by a formative force that played on a large scale the role alchemical theories attributed to ferments. That force is gravitation, which Newton associates in this text with the spirit of God. In this respect, the philosopher’s reconstruction has much in common with the chrysopoetic treatises that develop the analogy between the alchemical Magisterium and Genesis. Newton himself had drafted commentaries around these readings, in a period close to the time of his letter to Burnet. (shrink)

Policy-makers use different decision-making strategies and base their decisions – more or less explicitly – on both expert knowledge and opinions in order to cope with the sheer complexity of societal challenges and the political environment. Most politicians rely to some extent on personal ideology in the implementation of public policies. Potential decision biases such as ‘repair service behavior’ – the human tendency to try fixing what appears to be most problematic at first – also influence decision-making. While ideology plays (...) a prominent role in politics, we know too little about its effect on political decision-making. Some researchers would argue that the use of ideology and repair service behavior facilitate the decision process, while others suggest that it adversely affects the ability to make objective decisions. Using a political microworld simulation that reproduces complex real-world problems, we investigate the effects of repair service behavior and personal ideology on performance in a dynamic decision-making task. Although repair service behavior was not associated with performance, the results suggest that personal ideology significantly impaired goal attainment. Despite clear instructions to be as objective as possible and think critically in completing the task, ideology was powerful enough to disrupt objective policy-making, as indicated by the deviation from optimal scores and the overall microworld task goal, i.e., to win votes and be re-elected by the end of the game.

Although being generally safe, the use of Deep Brain Stimulation has been associated with a significant number of patients experiencing postoperative psychological and neurological harm within experimental trials. A proportion of these postoperative severe adverse effects have lead to the decision to medically prescribe device deactivation or removal. However, there is little debate in the literature as to what is in the patient’s best interest when device removal has been prescribed; in particular, what should be the conceptual approach to ethically (...) guide the decision to remove or maintain implants. The purpose of this article is to examine the ethical issues raised when patients refuse brain device explantation despite medical prescription. In order to illustrate these issues, we report and discuss a clinical case involving a patient suffering from treatment resistant depression who experienced forms of postoperative self-estrangement, as well as suicidal attempts, but who resists giving consent to device explantation.

Motivated by the search for a Hamiltonian formulation of Einstein equations of gravity which depends in a minimal way on choices of coordinates, nor on a choice of gauge, we develop a multisymplectic formulation on the total space of the principal bundle of orthonormal frames on the 4-dimensional space-time. This leads quite naturally to a new theory which takes place on 10-dimensional manifolds. The fields are pairs of \,\varpi )\), where \\) is a 1-form with coefficients in the Lie algebra (...) of the Poincaré group and \ is an 8-form with coefficients in the dual of this Lie algebra. The dynamical equations derive from a simple variational principle and imply that the 10-dimensional manifold looks locally like the total space of a fiber bundle over a 4-dimensional base manifold. Moreover this base manifold inherits a metric and a connection which are solutions of a system of Einstein–Cartan equations. (shrink)

Renowed historian E.P. Thompson (1924-1993) single-handedly changed the marxist understanding of class and class consciousness in his pivotal book The Making of the English Working Class (1963). Thompson not only took issue with the economic and technological determinism that plagued marxist theory, he also took issue with philosophers — Althusser, Foucault, Horkheimer, Adorno, Marcuse, etc. — who variously described history as a process without a subject. Thompson was wary of philosophers. He nonetheless approvingly quotes Maurice Merleau-Ponty (1908-1961) in his polemical (...) essay The Poverty of Theory (1978). This surprising reference went unnoticed to this day. Following Thompson’s original reference to Merleau-Ponty’s The Structure of Behavior (1942) leads one to a number of observations that the french philosopher made to history, social classes and class counsciousness in works such as Phenomenology of Perception (1945), Sense and Non-Sense (1948) and the Adventures of the Dialectic (1955). Those various observations show that Thompson and Merleau-Ponty shared the same phenomenological understanding of class consciousness. (shrink)

Investigating the neo-Kantian origins of structuralism and culturalism, this article analyses the development of Cassirer's thought by following his intellectual progression from knowledge to culture, and from culture to praxis. The article is in two parts. In the first part, the author presents an analysis of Cassirer's relational conception of knowledge. In the second part, the critique of knowledge is superseded by a critique of culture. The author analyses Cassirer's anthropological philosophy of symbolic forms and critically compares it to Simmel's (...) vitalist theory of culture. The article ends with a plea for a practical sociology inspired by Cassirer's return to Kant's practical philosophy. (shrink)

Among the casualties of the rush to relativism is a central tenet of classical thought: that great works of literature are great in and of themselves and not because of the needs and values of their time. This “canon-based view,” supply taken for granted by Johnson, Arnold, Pope, and Eliot, has long since been shown the door by views ranging from Marxism to today’s cultural studies. These views hold that the great works become great because of the values and concerns (...) of their own times, and they remain effectual, if they do, because of the ways they speak to their times’ concerns. There are no transhistorical values and concerns, though of course there is a past to culture and its works continue their indirect .. (shrink)

An argument opposing the unrestricted use of quantification in modal logic has been put forward by Quine. Central to this argument are the two phrases, The Morning Star, The Evening Star.One form of the argument is obtained by considering the following two statements: It is necessary that the Morning Star is identical with the Morning Star. It is not necessary that the Evening Star is identical with the Morning Star.

Aristotle considered the plot the most important element in tragedy. By μῦθυς--from which our word "myth" comes--he meant an imitation of action--of action in the "real world," that is. Here, as elsewhere in Greek literary criticism, "imitation" does not mean simply "exact reproduction." To what extent it may mean something like "symbolic," or otherwise "oblique," representation, is hard to determine. It will be enough, for our purposes, to think of "imitation" as exact reproduction with allowance made simply for the transference--always (...) radically transforming--into another medium: from life into art. What, then, did Aristotle mean by "action"? The noun πρᾶξις takes us back to the verb πράττω. Action meant a "doing" to Aristotle, rather as poetry meant to him a "making." Such a "doing," then, is a time-crossing event, in fact an event whose nature is closely involved with its temporal status. Such an event has a personal agent, or vehicle, and transacts with other persons, or more generally, with the "other." In fact, the notion of a transaction is especially fitting to describe action, for that notion emphasizes the dialogue-like structure of action, which always involves its agent with "the world," whether of people or of things. Plot, for Aristotle, was the turning of such action into art. (shrink)

We resolve a useful formulation of the question how a statistician can coherently incorporate the information in a consulted expert’s probability assessment for an event into a personal posterior probability assertion. Using a framework that recognises the total information available as composed of units available only to each of them along with units available to both, we show: that a sufficient statistic for all the information available to both the expert and the statistician is the product of their odds ratios (...) in favour of the event; that the geometric mean of their two probabilities specifies a contour of pairs of assertions in the unit-square that yield the same posterior probability; that the information-combining function is parameterised by an unknown probability for the event conditioned only on the unspecified information common to both the statistician and the expert; and that an assessable mixing distribution over this unspecified probability allows an integrable mixture distribution to represent a computable posterior probability. The exact results allow the identification of the subclass of coherent probabilities that are externally Bayesian operators. This subclass is equivalent to the class of combining functions that honour the principles of uniformity and compromise. (shrink)

Does Michel Henry’s Phenomenology of life include an ethical and political dimension? It appears that the writings about Marx already include such aspects, especially in reference to the problem of social determinism. More generally, however, our attention must be focused on what Henry calls the transcendental genesis of politics which accounts for the lack of autonomy of the political field, just like in the case of economics. Politics may then be analyzed against that background, for instance in the writings on (...) totalitarianism and democracy. The frame given by transcendental genesis is also tied to the fundamental opposition between barbarism and culture which pervades the axiological implications of Henry’s work. Because culture is always referring to a “culture of life,” it allows connecting life and its immanent reality with ethical/political questions. (shrink)

L’importance des sources néoplatoniciennes de la philosophie première de Jankélévitch s’inscrit dans la lignée de l’enseignement de Bréhier qui le met sur la voie d’une « négation libératrice ». La fidélité à Bergson et la lecture de Schelling ne pouvaient néanmoins que reconduire la tentative de dépassement de la logique qui en résulte à une forme d’expérience pure qui recherche la plénitude dans une adéquation à la vie. Ainsi, « l’évanouissante entrevision » à laquelle Jankélévitch nous condamne à tendre sans (...) jamais l’atteindre, rivés que nous sommes à notre finitude, marque-t‑elle tout autant une forme de distance vis-à-vis de la philosophie de Plotin. La compréhension de cet héritage critique pourra ainsi nous permettre de mieux cerner ce qui sépare le vitalisme de Jankélévitch de l’idéalisme néoplatonicien, c’est-à-dire ce qui demeure incompatible entre la logique de la vie et la dialectique de la pensée.

The prominent Russian philosopher Nikolai Lossky and his ex-student Nicolai Hartmann shared many metaphysical and epistemological views, and Lossky is likely to have influenced Hartmann in adopting several of them. But, in the case of axiological issues, it appears that Lossky also borrowed from the axiologies of Hartmann and the latter's Cologne colleague, Max Scheler. The links between the theories of values of Scheler and Hartmann have been studied abundantly, but never in relation to Lossky. In this paper, I examine (...) the manifold relationships – similarities, differences, borrowings, criticisms, and possible influences – between Lossky's axiology and those of Scheler and Hartmann on four key interweaving issues: (1) their ontological realism with regards to the objectivity of values, (2) their epistemological theories of the intuition of values, (3) their ontological definitions of "value", i.e., whether values are relations, qualities, essences, powers, meanings, etc., and (4) their theories of the stratification of values.

The SIMS model offers an embodied perspective to cognition and behaviour that can be applied to organizational studies. This model enriches behavioural and brain research conducted by social scientists on emotional work (also known as emotional labour) by including the key role played by body-related aspects in interpersonal exchanges. Nevertheless, one could also study a more vocal aspect to smiling as illustrated by the development of strategies in organizations. We propose to gather face-to-face and voice-to-voice interactions in an embodied perspective (...) taking into account Lakoff and Johnson's (1980) theory of conceptual metaphors. (shrink)

Les thèses que Proudhon développe sur les femmes, l’amour et le mariage n’expriment pas seulement sa misogynie personnelle, elles remplissent aussi une fonction centrale dans sa théorie de la justice.

Condition de leur complémentarité, l’inégalité foncière entre femmes et hommes sanctifiée dans le mariage rend seule possible l’émergence d’une société d’hommes libres (...) et égaux. (shrink)

Parmi les philosophies qui tentent de faire face à la crise de la rationalité, certaines, plus radicales que d’autres, en proposent une fondation reposant sur des principes qui se veulent exempts de toute présupposition. Ainsi K. O. Apel entend opérer une refondation de la rationalité éthique et cognitive en considérant les activités communicationnelles et argumentatives. Il s’agit d’élaborer une «pragmatique transcendantale» dont le processus d’étayage auto-réflexif s’appuie sur la «contradiction pragmatique» dans laquelle tombent ses éventuels contradicteurs. Une telle prétention n’est-elle (...) pas exorbitante ? Les sceptiques grecs ont élaboré une approche pragmatique du sens qui leur permet d’éviter la disqualification de leur énonciation, ce qui permet, en transposant leurs conceptions à la lumière des théories contemporaines du langage, d’échapper à la critique de Apel. On peut dès lors reconnaître le caractère constitutif de l’activité communicationnelle, sans prétendre en proposer une fondation ultime de type transcendantal, ni préjuger de son orientation éthique. Resterait à se demander s’il est possible de reconstruire une rationalité minimale compatible avec la posture sceptique. (shrink)

The study of human origins is a kaleidoscopic field, a multitude of objects, reflections, and disciplines a swirl in an ever-changing tumult. The extreme diversity of the elements of information that are indispensable to this field of study (teeth, bones, apes, genes, ancient objects, present-day objects, biomechanical factors, cultural constructions …) appears all by itself to be enough to consign any attempt at synthesis to the realm of the Utopian. It hardly seems reasonable to expect the disparate sciences that fuel (...) the field (paleoanthropology, archaeology, molecular biology, physics, psychology, and others) and the contradictory conceptions of scientific activity that they defend (human sciences, natural sciences, experimental sciences, exact sciences) to be joined with any regularity. As for formulating an overall problematics of the interdependent phenomena encountered in the field, one would have to be more than optimistic to entertain such dreams. And yet this is exactly the program that prehistory and paleoanthropology are laboring to construct tinder the label “the study of the origins of man,” an expression that includes both diachronic processes (human evolution) and activities or behaviors from particular moments, elements that are exceedingly difficult to compare given the separation of their geographic and temporal contexts.

Animals have evolved complex foraging strategies to obtain a nutritionally balanced diet and associated fitness benefits. Recent research combining state-space models of nutritional geometry with agent-based models (ABMs), show how nutrient targeted foraging behavior can also influence animal social interactions, ultimately affecting collective dynamics and group structures. Here we demonstrate how social network analyses can be integrated into such a modeling framework and provide a practical analytical tool to compare experimental results with theory. We illustrate our approach by examining the (...) case of nutritionally mediated dominance hierarchies. First we show how nutritionally explicit ABMs that simulate the emergence of dominance hierarchies can be used to generate social networks. Importantly the structural properties of our simulated networks bear similarities to dominance networks of real animals (where conflicts are not always directly related to nutrition). Finally, we demonstrate how metrics from social network analyses can be used to predict the fitness of agents in these simulated competitive environments. Our results highlight the potential importance of nutritional mechanisms in shaping dominance interactions in a wide range of social and ecological contexts. Nutrition likely influences social interactions in many species, and yet a theoretical framework for exploring these effects is currently lacking. Combining social network analyses with computational models from nutritional ecology may bridge this divide, representing a pragmatic approach for generating theoretical predictions for nutritional experiments.

l'Histoire du scepticisme d'Érasme à Spinoza de Richard H. Popkin n'est pas seulement le récit des diverses doctrines sceptiques qui traversent le XVIe et le XVIIe siècle: un fil conducteur confère à l'ensemble sa cohérence. Mieux, une conception générale de la philosophie moderne sous-tend ses analyses. Selon Popkin en effet, toute la philosophie, depuis la Renaissance jusqu'aux lumières, s'est trouvée confrontée à la tâche de surmonter la «crise pyrrhonienne», née en contexte de querelle religieuse, et qui très vite s'étend à (...) tout le savoir. Popkin a ainsi proposé une interprétation originale mais peut-être aussi parfois contestable de la modernité, en particulier dans la mesure où il ne distingue pas assez nettement le scepticisme ancien du moderne, et où il ne prend pas en compte la spécificité du fidéisme.

A system of natural deduction rules is proposed for an idealized form of English. The rules presuppose a sharp distinction between proper names and such expressions as the c, a (an) c, some c, any c, and every c, where c represents a common noun. These latter expressions are called quantifiers, and other expressions of the form that c or that c itself, are called quantified terms. Introduction and elimination rules are presented for any, every, some, a (an), and the, (...) and also for any which, every which, and so on, as well as rules for some other concepts. One outcome of these rules is that Every man loves some woman is implied by, but does not imply, Some woman is loved by every man, since the latter is taken to mean the same as Some woman is loved by all men. Also, Jack knows which woman came is implied by Some woman is known by Jack to have come, but not by Jack knows that some woman came. (shrink)

Contemporary capitalism is in effect, if not in intent, Deleuzian. As a network of networks, it is rhizomatic, flexible, chaosmotic, evolving, expanding.
