© 2017. The American Astronomical Society. 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)

A dual-language edition presenting Descartes's original Latin text of his greatest work, with a facing-page authoritative English translation.

Desde o ano de 1643, Descartes (1596-1650) e a princesa Elizabeth (1618-1680) já trocavam cartas a respeito da geometria, da metafísica e até da física cartesiana. Todavia, no ano de 1645, por conta de um grave estado melancólico da princesa, houve uma intensa correspondência entre ambos. À princípio, o debate se mantinha em torno das condições especificas da princesa. O tema central girava em torno de questões fisiológicas e morais (ou psicofisiológicas). À medida, porém, em que a troca de correspondência (...) se intensificava, o debate ia tornando-se cada vez mais teórico, passando pela discussão da Vida Beata, de Sêneca, até forçar Descartes a apresentar os primeiros esboços de sua própria concepção moral. Dessa troca de correspondência, escolhemos duas cartas de setembro de 1645: uma do filósofo a Elizabeth (carta CDIII) e outra da princesa a Descartes carta (CDVI). (shrink)

This study examined the hypothesis that conditional reasoning involves visual short-term memory resources (Johnson-Laird, 1985). A total of 147 university students were given measures of verbal and visual short-term memory capacity and a series of concrete and abstract conditional reasoning problems. Results indicate that there is a positive correlation between verbal working memory capacity and reasoning with both concrete and abstract premises. A positive correlation was also obtained between visual working memory capacity and reasoning with concrete premises.

The notions of perceptual normativity and optimality have generated much discussion in the last decade or so in the literature on Merleau-Ponty. Husserl’s position on the topic has been far less extensively investigated. Surprisingly, however, Husserl wrote a great deal about the question of perceptual optimality. Not only are there a considerable number of important passages scattered throughout the manuscripts, the archive also contains a few important full texts on precisely this issue. Given the role of fulfillment for Husserl’s concept (...) of intentionality, this should not really come as a surprise, since the teleological nature of the fulfillment structure terminates in an experience of the optimum. Hence, however marginal this topic might seem at first glance, reflecting on it rapidly leads us to the heart of Husserl’s project and sheds further light on his conception of intentional experience.

A Egmond, le 16 avril 1648, un peu moins de deux ans avant sa mort, Descartes s'entretient avec un étudiant hollandais en théologie, Frans Burman. Le jeune homme de vingt ans présente au philosophe de courts extraits de ses principales oeuvres publiées (Méditations métaphysiques, Principes de la philosophie, Discours de la méthode) que l'auteur en personne se charge d'expliquer, répondant aussi aux objections de son interlocuteur. Ce texte possède donc un statut décisif dans le corpus cartésien car il s'agit d'un (...) commentaire des points les plus délicats de la philosophie de Descartes par lui-même. Ce faisant, il ne se contente pas de répéter ce qu'il a déjà écrit sur le doute, la connaissance sensible, l'existence de Dieu, le mouvement de la matière ou encore la santé du corps, il ne cesse au contraire d'approfondir, de nuancer, voire de transformer les thèses sur lesquelles il est interrogé. Ce texte interdit ainsi de faire de la pensée de Descartes une "doctrine" stable et immuable. Il donne plutôt à voir de manière éclatante une pensée en marche, celle d'un philosophe majeur et reconnu qui accepte pourtant de remettre sur la table de travail les points essentiels d'une oeuvre déjà constituée en fonction des questions précises qui lui sont posées. Bien plus qu'un simple résumé de sa philosophie, cet Entretien montre l'inlassable exigence de l'effort de la pensée cartésienne à la conquête de sa propre clarté. (shrink)

Most twentieth‐century European philosophers have attempted to think anew the Kantian question about the necessary conditions of experience. A rapid survey of last century's European philosophy would easily show that in spite of the various criticisms formulated against the very project of transcendental foundationalism, the vast majority of the philosophers in the so‐called Continental tradition have not abandoned the project of formulating transcendental arguments altogether. These transcendental inquiries into the conditions of possibility of all these phenomena are certainly more immediately (...) visible in the early works, especially those on Husserl, but a patient reading would show that they are still very much present in the later writings as well. The overcoming of classical transcendentalism at work in deconstruction is indeed the outcome of an ultra‐transcendental strategy. In Of Grammatology, Derrida exposes this ultra‐transcendental logic for the first time when he famously claims that a “pathway” through the transcendental is necessary. (shrink)

This study evaluated the integration of psychology ethics into an introductory psychology course. Students in two general psychology sections were exposed to an infusion of psychology ethics in teaching, research, and clinical practice, whereas students in two sections were exposed to traditional course content. Students completed a pre and post-test assessment including a psychology ethics questionnaire and open-ended responses to three ethics case studies. Students in the ethics group displayed a statistically significant increase in scores on both measures from pre (...) to post-test. However, students in the traditional group showed no improvement in scores. (shrink)

Human activity is permeated by norms of all sorts: moral norms provide the 'code' for what we ought to do, norms of logic regulate how we ought to reason, scientific norms set the standards for what counts as knowledge, legal norms determine what is lawfully permitted and what isn't, aesthetic norms establish canons of beauty and shape artistic trends and practices, and socio-cultural norms provide criteria for what counts as tolerable, just, praiseworthy, or unacceptable in a community or milieu. Given (...) the diversity of norm-governed phenomena prevailing in our everyday experience, it is not surprising that the question of normativity has recently generated important debates in philosophy. However, the more specific question concerning the nature and function of 'norms in perceptual experience' has received comparatively little attention. This volume brings together scholars from philosophy of mind, philosophy of perception, and phenomenology to explore this question. (shrink)

In his collection of essays Having the World in View (2009), John McDowell draws a distinction between empirical experience (conceived as the conceptual activity relevant to judgment) and empirical judgment (i.e., the full-fledged assertoric content itself ). McDowell’s latest proposal is that the form of empirical experience is transferable into judgment, but it is not itself a judgment. Taking back the view he advanced in Mind and World, McDowell now believes that perception does not have propositional content as such, but (...) the content of perception can, however, always be actualized in a judgment. There is, in other words, a strict parallelism between the deliverances of sensibility and potential future judgments of experience. The early Husserl disagrees with this and recognizesexplicitly the existence of coherent forms of perceptual engagement with the world that is independent of the mastery of language and the use of concepts.Perception constitutes—together with certain other embodied practices—our primary mode of access to the world, and this occurs before and independently ofour thinking activity. However, the realization of the centrality of time for intentionality will lead Husserl after 1905 to recognize a kind of lawfulness internal tothe sensuous materials themselves, prior to any egoical achievement. The most immediate consequence of this paradigm change is that the very idea of non-conceptual content now seems unwarranted. Indeed, if time is that which keeps the process of sense formation unified even at the lowest levels of constitution, then the world-disclosing activity of the ego cannot be discontinuous with the conceptual realm. Against this background, it will be argued that the dialectic between the conceptual and non-conceptual ultimately makes no sense on a phenomenological basis. Once temporality has entered the scene, the only meaningful opposition that stands is that between the conceptual and pre-conceptual spheres. (shrink)

Law-enforcement agencies are increasingly able to leverage crime statistics to make risk predictions for particular individuals, employing a form of inference that some condemn as violating the right to be “treated as an individual.” I suggest that the right encodes agents’ entitlement to a fair distribution of the burdens and benefits of the rule of law. Rather than precluding statistical prediction, it requires that citizens be able to anticipate which variables will be used as predictors and act intentionally to avoid (...) them. Furthermore, it condemns reliance on various indexes of distributive injustice, or unchosen properties, as evidence of law-breaking. (shrink)

Theory of Literature was originally published in 1949. It is not a textbook introducing the young to the elements of literary appreciation nor a survey of the techniques employed in scholarly research. The authors have sought to unite "poetics" (or literary theory) and "criticism" (evaluation of literature) with "scholarship" ("research") and "literary history" (the "dynamics"of literature, in contrast to the "statics" of theory and criticism).

The paper is organized around two ideas that come out in Steve Crowell’s Normativity and Phenomenology in Husserl and Heidegger and that I discuss critically in turn. The first concerns the reach of Crowell’s claim according to which the connection between intentionality, meaning and normativity is necessary in all forms of intentional experience. I make my point by considering the case of imagining experiences, which are—I argue—meaningful, intentional, but not necessarily normative in any relevant sense. The second question is about (...) Crowell’s criticism of the role of bodily self-awareness in Husserl’s phenomenology of perception. While Crowell is right to maintain that the norm of proper functioning relevant to bodily skills can’t be understood as arising from a system of kinaesthetic sensations alone, I argue that bodily self-awareness still has a normative role to play in perception inasmuch as it allows me to cast my own experience in evaluative terms.

Presentation times of study words presented in the Deese/Roediger and McDermott (DRM) paradigm varied from 20 to 2000 ms per word in an attempt to replicate the false memory effect following extremely short presentations reported by . Both in a within-subjects design (Experiment 1) and in a between-subjects design (Experiment 2) subjects showed memory for studied words as well as a false memory effect for related critical lures in the 2000-ms condition. However, in the conditions with shorter presentation times (20 (...) ms in Experiment 1; 20 and 40 ms in Experiment 2) no memory for studied words, nor a false memory effect was found. We argue that there is at present no strong evidence supporting the claim for a nonconscious basis of the false memory effect. (shrink)

This is the first book in which contemporary scientists and mystics share with us-in their own words-their views on space, time, matter, energy, life, consciousness, creation and on our place in the scheme of things. The book is also the story of an American philosopher who-with these dialogues-ventures into ground-breaking territory, and of her search in America, Europe, India and Nepal for people whose work is at the center of our understanding of reality.

Chaos theory is a rapidly growing field. As a technical term, chaos refers to deterministic but unpredictable processes being sensitively dependent upon initial conditions. Neurobiological models and experimental results are very complicated and some research groups have tried to pursue the neuronal chaos. Babloyantz's group has studied the fractal dimension (d) of electroencephalograms (EEG) in various physiological and pathological states. From deep sleep (d=4) to full awakening (d>8), a hierarchy of strange attractors paralles the hierarchy of states of consciousness. In (...) epilepsy (petit mal), despite the turbulent aspect of a seizure, the attractor dimension was near to 2. In Creutzfeld-Jacob disease, the regular EEG activity corresponded to an attractor dimension less than the one measured in deep sleep. Is it healthy to be chaotic? An active desynchronisation could be favourable to a physiological system. Rapp's group reported variations of fractal dimension according to particular tasks. During a mental arithmetic task, this dimension increased. In another task, a P300 fractal index decreased when a target was identified. It is clear that the EEG is not representing noise. Its underlying dynamics depends on only a few degrees of freedom despite yet it is difficult to compute accurately the relevant parameters.What is the cognitive role of such a chaotic dynamics? Freeman has studied the olfactory bulb in rabbits and rats for 15 years. Multi-electrode recordings of a few mm2 showed a chaotic hierarchy from deep anaesthesia to alert state. When an animal identified a previously learned odour, the fractal dimension of the dynamics dropped off (near limit cycles). The chaotic activity corresponding to an alert-and-waiting state seems to be a field of all possibilities and a focused activity corresponds to a reduction of the attractor in state space. For a couple of years, Freeman has developed a model of the olfactory bulb-cortex system. The behaviour of the simple model without learning was quite similar to the real behaviour and a model with learning is developed. (shrink)

While common sense and rationality often have been viewed as two distinct features in a unitifed cognitive map, this this volume offers novel, even paradoxical views of the relationship. Touching on various disciplines, it considers what constitutes human rationality, behavior, and intelligence.

Recently, an increasing number of scholars have been showing interest in old-fashioned racism again. While recent studies on old-fashioned racism apparently increase our knowledge of this psychological theory of racism, the studies actually shed light on a different type of racism, namely offensive racism. The aim of this text is to argue that psychological theories of racism, like old-fashioned racism and modern racism, depend on societies’ social norms. I will show that questionnaires are highly sensitive to social norms, and if (...) there is change in social norms, the original measurement object alters. The theory of old-fashioned racism implicitly assumes agents that follow (or conform to) the social norm to behave prejudiced. Today, however, this social norm does not exist in Western societies. If agents express the same prejudices today, they indicate their willingness to breach the social norm to behave unprejudiced. Thereby, classic old-fashioned racism measures reflect a new kind of racism today. (shrink)

In _Battling to the End _René Girard engages Carl von Clausewitz, the Prussian military theoretician who wrote _On War_. Clausewitz, who has been critiqued by military strategists, political scientists, and philosophers, famously postulated that "War is the continuation of politics by other means." He also seemed to believe that governments could constrain war. Clausewitz, a firsthand witness to the Napoleonic Wars, understood the nature of modern warfare. Far from controlling violence, politics follows in war's wake: the means of war have (...) become its ends. René Girard shows us a Clausewitz who is a fascinated witness of history's acceleration. Haunted by the French-German conflict, Clausewitz clarifies more than anyone else the development that would ravage Europe. _Battling to the End _pushes aside the taboo that prevents us from seeing that the apocalypse has begun. Human violence is escaping our control; today it threatens the entire planet. (shrink)

Le présent essai porte sur la question de la place de la critique des religions en philosophie et dans l'espace public. C'est une discussion franche avec des philosophes québécois qui défendent la liberté de religion comme si cette liberté était la forme exemplaire des libertés fondamentales d'une société démocratique. Les croyances religieuses échappent-elles à la science? Est-il vraiment rationnel de croire que la nature est l'œuvre d'une intelligence surnaturelle? Pourquoi la croyance religieuse est-elle érigée en norme? Quelle est la place (...) de la religion à l'école? Peut-on dissocier la morale de la religion? Sans aller jusqu'à conclure que les religions doivent être éliminées ou que la science détient le monopole de la vérité, il ressort de cette analyse rigoureuse que l'attitude de traitement préférentiel des religions est injuste envers les non-croyants et qu'elle est en bonne partie la cause de la querelle sur la laïcité. " La position que défend ici Doyon est somme toute pérenne : sans aller jusqu'à remonter à Lucrèce et à quelques autres auteurs de l'Antiquité, elle est nettement celle qui se déploie à partir du Siècle des Lumières, et que diversement et de manière complémentaire formulent en France des gens comme Condorcet, D'Holbach, Buisson et d'autres. L'incontournable question que nous laisse ce bel ouvrage est dès lors de savoir s'il faut modifier cette position canonique ou si ce n'est pas plutôt pour s'en être éloigné que nous faisons aujourd'hui face aux difficultés qui sont les nôtres." – Normand Baillargeon, extrait de la préface.

According to the standard view on the issue, the habit of marking questions with a particular typographical sign in Greek and Latin script does not arise prior to the eighth or ninth century. This period is generally credited with the ‘invention’ of the question mark (excepting Syriac evidence, which points to the fifth and sixth centuries). The purpose of the present article is to correct this view. It argues that the first indication for the use of a typographical sign that (...) marks questions can actually be detected no later than during the reign of Emperor Hadrian (a.d. 117–38), that is, more than half a millennium before the traditional date of the invention. The chief witness is Nicanor of Alexandria, who does not seem to have used question marks himself, but criticizes the misappropriation of another punctuation mark to that purpose. He thus indirectly testifies to the existence of question marks. Comparable traces can also be found later in the exegetical works of some Christian commentators. (shrink)

A concise summary of Nicanor’s theory of punctuation that has recently been discovered in a codex mixtus of the 15th century throws precious new light on a topic of some complexity. The general picture that emerges from the new extract does not substantially differ from that of the other known summary, which has been the starting point for all modern reconstructions of Nicanor’s theory. Therefore, these reconstructions need not be rewritten on a larger scale. The two summaries nevertheless display some (...) telling differences in how they explain and present the details, not least when read against the backdrop of Nicanor’s actual practice that can be derived from the relevant scholia to Homer. The purpose of the present article is to assess the new discovery especially with regard to these differences and their effects on how Nicanor’s theory is to be reconstructed. (shrink)
