"Et toutes ces belles idées sur la liberté, elles sont appliquées quelque part? - Ensemble, non. Mais par petits bouts, oui. Enfin, je crois. - Hé bien, tu n'as qu'à aller voir." C'est ainsi que je fus arraché à la torpeur de ma bibliothèque. Depuis lors, je voyage à travers le monde avec une ambition simple : étudier les thèmes de philosophie politique qui me sont chers là où ils sont mis en oeuvre. Faire apparaître derrière les concepts des histoires, (...) des visages. Pour comprendre la tolérance religieuse, j'ai parcouru le Kerala, en Inde, où les grands monothéismes coexistent depuis la nuit des temps. Pour me faire une opinion sur le libre-échange, j'ai suivi dans son quotidien le directeur de l'Organisation mondiale du commerce. Pour tester la libéralisation des drogues, j'ai côtoyé les entrepreneurs de la marijuana au Colorado. Pour mieux saisir les enjeux du revenu universel, j'ai enquêté dans les villages brésiliens où il est expérimenté. Pour apprécier la réalité du micro-crédit, j'ai sillonné les bidonvilles de Lima. Et pour m'assurer des vertus de la liberté, j'ai rencontré ceux qui en sont privés, dans les "prisons ouvertes" finlandaises. Chemin faisant, j'ai perdu certains préjugés, découvert de nouvelles idées, croisé des auteurs insoupçonnés. Et j'ai acquis une conviction : les problèmes posés par la liberté se résolvent par... davantage de liberté. G.K. (shrink)

In an 1894 manuscript addendum to the seminal "How to Make Our Ideas Clear", which he had written in 1877, Charles Peirce stated that "there are many people who detect the authorship of my unsigned screeds; and I doubt not that one of the marks of my style by which they do so is my inordinate reluctance to repeat a word". However, if Peirce refrained from repeating words in one and the same sentence, he surely did not refrain from repeating (...) words throughout all his writings, as this brief report will show. Here, we present the results of a lexicometric analysis performed on the vocabulary present in the Collected Papers of Charles Sanders Peirce, as they were edited and published by... (shrink)

ABSTRACTIn this article I propose to interpret Austin's conception of perlocution in light of Peirce's philosophy of signs, through the lens of his notions of thirdness and speculative rhetoric in particular. I suggest that the traditional notion of speech genre, examined within the context of Peirce's semiotic framework, can make sense of the regularities and predictability that are characteristic of a large part of our discursive practices. More specifically, I argue that crystallized “habits of interpretation,” correlated to purposeful speech genres (...) instantiated in given circumstances of enunciation, could be construed as predetermining the range of future interpretive conduct. In that perspective, this process of determination could be thus conceived as relatively predictable, at least for communication situations activating well-defined speech genres. In the end, I suggest that Peirce's conception of rhetoric draws attention to the necessarily constrained interpretive habits of our discursive life, yielding an original perspective on the notion of perlocution.

This article focuses on discursive regularities that can generally be observed in text corpora produced in similar communication situations (medical interviews, political debates, teaching classes, etc.). One type of such regularities is related to the so-called ‘discourse genres’, considered as a set of tacit instructions broadly constraining the forms of utterances in a given discursive practice. Those regularities highlight the relatively regulated, non-random nature of most of our discursive practices and epitomize the necessary constrained creativity of meaning making in discourse. (...) In this perspective, we suggest that the concepts of Thirdness and Habit, as theorized by Charles S. Peirce, can be fruitful in describing the role and importance of such regularities in our sociodiscursive life. More specifically, we believe that discourse regularities are ideal case studies if one wishes to investigate instances of predictability in semiotic (discursive) processes. Overall, we suggest that their study can be one of many research orientations through which a prediction-based scientific conception of semiotics could be applied. (shrink)

The hypothesis that the particular linear tracks appearing in the measurement of a spherically-emitting radioactive source in a cloud chamber are determined by the positions of atoms or molecules inside the chamber is further explored in the framework of a recently established one-dimensional model. In this model, meshes of localized spins 1/2 play the role of the cloud-chamber atoms and the spherical wave is replaced by a linear superposition of two wave packets moving from the origin to the left and (...) to the right, evolving deterministically according to the Schrödinger equation. We first revisit these results using a time-dependent approach, where the wave packets impinge on a symmetric two-sided detector. We discuss the evolution of the wave function in the configuration space and stress the interest of a non-symmetric detector in a quantum-measurement perspective. Next we use a time-independent approach to study the scattering of a plane wave on a single-sided detector. Preliminary results are obtained, analytically for the single-spin case and numerically for up to 8 spins. They show that the spin-excitation probabilities are sometimes very sensitive to the parameters of the model, which corroborates the idea that the measurement result could be determined by the atom positions. The possible origin of decoherence and entropy increase in future models is finally discussed. (shrink)

This essay focuses on Charles S. Peirce’s grammar of representation and its relevance for a logical conception of scientific inquiry. Closely relying on Peirce’s writings, one of his important trichotomies of signs will be discussed in particular: that distinguishing between substitutive signs, or “semes”, informational signs, or “phemes”, and persuasive signs, or “delomes”. According to Peirce, these three categories of signs result from an extension of the traditional division between “terms”, “propositions”, and “arguments” to all signs, understood as the foundational (...) elements with and on which the scientific mind operates. It is shown that such an extended view of logic, conceived as a “semiotic”, or general doctrine of signs, is consistent with Peirce’s metaphysical views on truth and reality. Logic-as-semiotic, and its three corresponding branches of stecheotic, critic, and methodeutic, is thus conceived as a requisite normative trivium for the practice of scientific inquiry, whose purpose is to represent reality truthfully. In the end, we aim to remind that Peirce’s semiotic epistemology must necessarily be contextualized within the frame of his comprehensive philosophy of the scientific “settlement of opinion”.

This essay attempts an overview of Peirce’s pragmaticist doctrine of the truth of propositions. Relying on his writings, I try to characterize his conception of the real and discuss the ways in which his peculiar scholastic metaphysics, opposing that of nominalists, is a central tenet of the pragmaticist view of truth which he strived to develop. Peirce conceived indeed real possibilities and real necessities to be just as real as actualities, those realities corresponding in nature to qualities (“firsts”), laws (“thirds”), (...) and existents (“seconds”), respectively. More specifically, I detail the peculiar mode of being of each kind of real elements and show that all three categories must be recognized at once in true propositions. This led Peirce to conclude that if propositions are general signs indeed and, as such, along with terms and arguments, are necessarily dependent on mind, it does not in the least preclude those propositions to be about, nor true of, a real world – a position which actually constitutes a necessary prerequisite for any meaningful conception of scientific inquiry. I believe that a focus on such interrelations between Peirce’s categorial account of the real and Peirce’s pragmaticist conception of truth constitutes an ideal testament to the systematic nature of his thought, which is an aspect often deflated in unspecialized literatures.

This paper reconsiders Frank Ramsey's essay on subjective probability (1926) as a consistent way to articulate logic, rationality and knowledge. The first part of the essay builds an axiomatic theory of subjective probability based on ‘formal logic’, defining rationality as choice-consistency. The second part seems to open up different horizons: the evaluation of degrees of belief by ‘human logic’. Because of the interest Keynes (1931) had taken in ‘human logic’, it was considered to be a possible alternative to the formal (...) logic underlying the neoclassical theory of individual behaviour. The analysis of Ramsey's method in the entire paper, the relation between logic and rationality it constructs and the conception of uncertainty it reveals, lead me to note on the contrary that Ramsey's human logic was a complementary logic rather than an alternative to formal logic. Defining a standard to evaluate beliefs formation according to a frequentist criterion, it completes a normative representation of rationality which supports an original theory of knowledge that appears more in line with further developments of neoclassical methodology than with Keynesian economics.

Un révolutionnaire sommeille en chaque Français, prêt hier comme aujourd'hui à briser les rentes et les privilèges. Dans le même temps, un expert l'observe et le dirige, planifiant autoritairement la société. Et un geek lui tape sur l'épaule, l'entraînant dans le monde inconnu des nouvelles technologies qui fourmille de promesses et de menaces. Ces trois influences parfois contradictoires nous font tourner la tête. Gaspard Koenig propose donc de les interpréter à la lumière d'une nouvelle philosophie politique, fondée sur l'autonomie (...) individuelle. Car ce dont la France a besoin, ce n'est pas d'un énième diagnostic économique, mais de principes solides dont on pourra déduire des réformes radicales. Revenons au modèle révolutionnaire, ce «jacobinisme libéral» incarné par le député du tiers état Isaac Le Chapelier. Rejetons la tentation planiste, léguée par le régime de Vichy et responsable encore aujourd'hui de tant d'injustice et d'exclusion. Apprenons à maîtriser l'utopie numérique, en imaginant un nouvel humanisme qui réponde aux défis de la Silicon Valley et un Etat 2.0 qui nous redonne le contrôle de notre destin numérique. Pays des libertés, la France meurt de servitude volontaire. Terminons, enfin, notre Révolution! Et chacun deviendra son propre maître. (shrink)

All rights reserved.We present new observations of the low-mass companion to HD 984 taken with the Gemini Planet Imager as a part of the GPI Exoplanet Survey campaign. Images of HD 984 B were obtained in the J and H bands. Combined with archival epochs from 2012 and 2014, we fit the first orbit to the companion to find an 18 au orbit with a 68% confidence interval between 14 and 28 au, an eccentricity (...) of 0.18 with a 68% confidence interval between 0.05 and 0.47, and an inclination of 119°with a 68% confidence interval between 114°and 125°. To address the considerable spectral covariance in both spectra, we present a method of splitting the spectra into low and high frequencies to analyze the spectral structure at different spatial frequencies with the proper spectral noise correlation. Using the split spectra, we compare them to known spectral types using field brown dwarf and low-mass star spectra and find a best-fit match of a field gravity M6.5 ±1.5 spectral type with a corresponding temperature of K. Photometry of the companion yields a luminosity of log=2.88 ± 0.07 dex with DUSTY models. Mass estimates, again from DUSTY models, find an age-dependent mass of 34 ±1 to 95 ±4 M Jup. These results are consistent with previous measurements of the object. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Journal of the History of Ideas 61.3 (2000) 415-432 [Access article in PDF] Christiaan Huygens's Attitude toward Animals Nathaniel Wolloch The debate on the status of animals has interested people since ancient times. In the early modern era this debate reached one of its most historically important and sedulous stages, drawing the attention of some of the most famous minds in Europe. Curiously enough, the historiography of this debate (...) has failed to take cognizance of the part played in it by the famous Dutch scientist Christiaan Huygens (1629-95), renowned for his invention of the pendulum clock, founding of the wave theory of light, and discovery of the true shape of the rings of Saturn, to name only a few of his prolific and varied activities. 1 While Huygens's contribution does not occupy a historically central part in this debate, which did not usually directly engross his attention, it is possible, based on some of his writings and activities, to piece together a picture of his general attitude toward animals. Such a study, as presented here, reveals more than anecdotal importance, since it both entails and affords an enlightening discussion of the connection between philosophy, science, and the treatment of animals, a discussion, moreover, which is relevant to the understanding not only of the early modern debate on animals, but also to the current debate of this issue. [End Page 415]One of the most prevalent features of the development of the attitude toward animals has been the recurrence of anthropocentric arguments. Such arguments were exhibited both by theriophiles (lovers of animals) and anti-theriophiles. 2 A significant instance of this is the recurring argument that harming animals is not bad in itself but rather because it might lead to the harming or corruption of human beings. While such an approach in effect states that those who are kind to animals would also be kind to human beings, it also implies that cruelty toward animals is excusable if committed to advance good causes, such as science and medicine. 3 Such anthropocentric views ultimately derive from both classical culture and philosophy, and especially the notion, rooted in biblical cosmology, according to which all of nature was given to man for his use by God, i.e., man was given the stewardship of nature. 4Theriophilic views which tend to regard animals as sentient beings in their own right became relatively common in early modern times. The most influential of these theriophiles was Michel de Montaigne, known for his love and praise [End Page 416] of animals, 5 and among the many theriophiles influenced by his views one of the most important was his disciple Pierre Charron. 6However, the most influential early modern view of animals, which became the main reference-point for the debate on animals, was anti-theriophilic. This was the Cartesian theory of the "beast-machine," which viewed animals as mere automata, devoid of an immortal soul as possessed by human beings; they were regarded as devoid of mind, and their behavior was compared to that of a clock. Descartes himself seems to have been rather agnostic regarding this issue. He did not deny animals some capacity for feeling but claimed that it was more probable they were senseless automata than beings with souls like human beings. 7 However, while many theriophiles attacked the beast-machine theory, its anti-theriophilic implications were developed and radicalized by various seventeenth-century Cartesians beyond what Descartes himself probably intended. The most prominent example of this was the leading Cartesian Nicolas Malebranche. The French intellectual Bernard Le Bovier, sieur de Fontenelle, related how he saw Malebranche, a generally kind man, kick a pregnant bitch, and when confronted with his (Fontenelle's) alarm, regarded this act as inconsequential, claiming that she did not feel a thing. 8 As cruel as the beast-machine [End Page 417] theory may seem, however, one should remember that it tried to explain away the suffering of animals. It implied that had such suffering been proven to exist, it would have required moral consideration. The views of Spinoza... (shrink)

This article examines the use of dialogues in two texts which functioned superficially as scientific handbooks for women: Aphra Behn's translation of Bernard le Bovier de Fontenelle's Entretien sur la pluralité des Mondes and Elizabeth Carter's Sir Isaac Newton's Philosophy Explained for the Use of Ladies (1739) translated from Francesco Algarotti's Il Newtoniasnismo Per le Dame (1737). Original texts exploit the female figure for the scientific cause, but at first glance, both of the original texts appeared generous to the (...) ‘fair sex’. However, neither text is as sympathetic as it initially appears. The confused gender messages emitted by these texts are further complicated by the fact that they were translated by women. (shrink)

ArgumentThis essay explores how and why women involved themselves in the sciences in eighteenth-century Italy. Using the case study of Diamante Medaglia Faini, a poet who attempted to become a mathematician, it argues that the image of the woman natural philosopher was shaped by the visible presence of woman in scientific institutions in the mid-eighteenth century and by the tradition of popular scientific writing, best embodied in the works of Bernard le Bovier de Fontenelle and Francesco Algarotti, that made (...) the woman natural philosopher an important literary protagonist. Becoming a scientist, in other words, was both a reality and a fiction. The tensions between these two different images shaped the terrain in which women pursued science. (shrink)
