Ce livre clôt une vie de travail au point de rencontre de la philosophie et des sciences. C'est tout notre vieux monde qui est ainsi ausculté, du cosmos à la cellule vivante, du hériodonte à l'homme, avec Kant, Merleau-Ponty ou d'Espagnat, Hawking, Berthoz, Damasio ou Chandebois, mais surtout avec Bergson. Ce dernier est quelque peu occulté aujourd'hui. Cet ouvrage le réhabilite, sans toutefois méconnaître les progrès accomplis depuis Bergson par les neurosciences et la neurophysiologie.

'A fabulous journey through thirty years of political and intellectual ferment... will reorient our reading of Foucault's major works' Didier Eribon The Essential Works of Michel Foucault offers the definitive collection of his articles, interviews and seminars from across thirty years of his extraordinary career. This first volume, Ethics, contains the summaries of Foucault's renowned courses at the Collège de France, as well as key writings and candid interviews on ethical matters: from the role of the intellectual and philosopher (...) in society to friendship, sexuality and the care of the self and others. Edited by Paul Rabinow Translated by Robert Hurley and Others. (shrink)

In this paper I take up the question of the nature of the doxastic attitudes we entertain while inquiring into some matter. Relying on a distinction between two stages of open inquiry, I urge to acknowledge the existence of a distinctive attitude of cognitive inclination towards a proposition qua answer to the question one is inquiring into. I call this attitude “hypothesis”. Hypothesis, I argue, is a sui generis doxastic attitude which differs, both functionally and normatively, from suspended judgement, (...) full belief, credences, and acceptance. In closing, I point to the epistemological significance of hypothesis. More specifically, I contend that holding an attitude of hypothesis enables us to respond rationally to peer disagreement, and I suggest that such an attitude offers a suitable articulation of the view, originally put forward by Philip Kitcher, that cognitive diversity in inquiry has epistemic benefits.

Prenatal genetic testing is becoming available for an increasingly broad set of diseases, and it is only a matter of time before parents can choose to test for hundreds, if not thousands, of genetic conditions in their fetuses. Should access to certain kinds of fetal genetic information be limited, and if so, on what basis? We evaluate a range of considerations including reproductive autonomy, parental rights, disability rights, and the rights and interests of the fetus as a potential future (...) child. We conclude that parents should be able to access information that could be useful during pregnancy, but that testing for non-medical information should be limited. Next, we argue that the government lacks a compelling state interest in regulating prenatal genetic testing and propose that regulation should occur through medical professional organizations. Finally, we present a framework for determining what testing physicians should recommend, offer neutrally, or not offer at all. (shrink)

The 1809 essay Philosophical Investigations into the Essence of Human Freedom and Related Matters marked a turning point in Schelling’s thinking about freedom. In various early works he had endorsed a compatibilist account of free will, arguing that acts could be free in the sense required for morally responsible agency, while still being necessary from a causal and even a metaphysical point of view. In later work he would endorse an incompatiblist conception of freedom as involving radical choice between good (...) and evil and entailing contingency in nature. The Freiheitsschrift is a point of transition, in which Schelling has introduced the idea that freedom must involve a radical choice between good and evil, but has not yet concluded that such a requirement is inconsistent with the compatibilism of his early system.

A theoretical physicist and feminist theorist, Karen Barad elaborates her theory of agential realism, a schema that is at once a new epistemology, ontology, and ethics.

The relationship between Albert Einstein’s special theory of relativity and Hendrik A. Lorentz’s ether theory is best understood in terms of competing interpretations of Lorentz invariance. In the 1890s, Lorentz proved and exploited the Lorentz invariance of Maxwell’s equations, the laws governing electromagnetic fields in the ether, with what he called the theorem of corresponding states. To account for the negative results of attempts to detect the earth’s motion through the ether, Lorentz, in effect, had to assume that the laws (...) governing the matter interacting with the fields are Lorentz invariant as well. This additional assumption can be seen as a generalization of the well-known contraction hypothesis. In Lorentz’s theory, it remained an unexplained coincidence that both the laws governing fields and the laws governing matter should be Lorentz invariant. In special relativity, by contrast, the Lorentz invariance of all physical laws directly reflects the Minkowski space-time structure posited by the theory. One can use this observation to produce a common-cause argument to show that the relativistic interpretation of Lorentz invariance is preferable to Lorentz’s interpretation. (shrink)

When he formulated the program of neurophenomenology, Francisco Varela suggested a balanced methodological dissolution of the hard problem of consciousness. I show that his dissolution is a paradigm which imposes itself onto seemingly opposite views, including materialist approaches. I also point out that Varela's revolutionary epistemological ideas are gaining wider acceptance as a side effect of a recent controversy between hermeneutists and eliminativists. Finally, I emphasize a structural parallel between the science of consciousness and the distinctive features of quantum mechanics. (...) This parallel, together with the former convergences, point towards the common origin of the main puzzles of both quantum mechanics and the philosophy of mind: neglect of the constitutive blindspot of objective knowledge.

“Ontological emergence” of inherent high-level properties with causal powers is witnessed nowhere. A non-substantialist conception of emergence works much better. It allows downward causation, provided our concept of causality is transformed accordingly.

This paper takes issue with the exemplarist strategy of fostering virtue development with the specific goal of improving its applicability in the context of education. I argue that, for what matters educationally, we have good reasons to endorse a liberal account of moral exemplarity. Specifically, I challenge two key assumptions of Linda Zagzebski’s Exemplarist Moral Theory (2017), namely that moral exemplars are exceptionally virtuous agents and that imitating their behavior is the main strategy for acquiring the virtues. I will introduce (...) and discuss the notions of enkratic exemplars and injustice illuminators and show that we have good reasons to consider them moral exemplars although they fail to satisfy (either of) the key assumptions.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 25.2 (2001) 233-250 [Access article in PDF] Narrative Theory and Function: Why Evolution Matters Michelle Scalise Sugiyama I It may seem a strange proposition that the study of human evolution is integral to the study of literature, yet that is exactly what this paper proposes. The reasons for this are twofold. Firstly, the practice of storytelling is ancient, pre-dating not only the advent of writing, but (...) of agriculture and permanent settlement as well. Secondly, narrative is ultimately a product of the mind, which in turn is the product of a long history of evolution by natural selection. Thus, an understanding of why and how humans create and consume narrative requires an understanding of (1) features of ancestral environments and (2) features of the mind that made the emergence of this phenomenon possible.There can be little doubt that narrative emerged in human prehistory. Language, an obvious prerequisite for storytelling, is likely to have emerged by at least 50,000 and possibly 250,000 years ago, depending upon whether one places one's trust in archaeological or anatomical evidence. 1 The most reasonable estimate is offered by Geoffrey Miller, who points out that, given its universality, the language faculty must have emerged by the time ancestral Homo sapiens began migrating out of Africa approximately 100,000 years ago. 2 Although the oldest known written narrative (The Epic of Gilgamesh) dates back only 5,000 years, the written literary traditions of many ancient cultures are known to be rooted in longstanding oral traditions. 3 The fact that many modern foraging peoples have rich and complex oral traditions further suggests that the emergence of narrative is not linked to the development of agriculture 10,000 years ago. Moreover, other forms of symbolic expression, such as the cave paintings, Venus figurines, and engraved bone [End Page 233] and antler that have been found at various sites throughout Europe, date back approximately 30,000 years, and rock paintings in Australia may date back even farther. 4 Since humans were physiologically capable of speech long before they began producing these artifacts, storytelling is likely to be at least as ancient as these other representational forms. Indeed, one scholar situates the "dawn of the oral tradition" within this period (Pfeiffer, p. 189). Given, then, that modern humans (Homo sapiens sapiens) have been in existence for approximately 100,000 years 5 and are the only hominid species or subspecies known for certain to exhibit storytelling behavior, we can safely say that oral narrative is a product of our hunting-and-gathering past, likely to have emerged between 30,000 and 100,000 years ago.The universality of narrative is further testimony to its being an ancient cognitive phenomenon. Literate or not, all known cultures, past and present, practice storytelling. 6 Moreover, all normally developing humans acquire the ability to process and generate stories: studies of Western children indicate that the ability to tell stories emerges spontaneously between the ages of two-and-a-half and three, and children as young as thirty months can distinguish between narrative and non-narrative uses of language. 7 In contrast to reading, writing, and arithmetic, no special education is required for narrative competence to develop, nor is there any evidence that oral literacy is acquired through contact with other cultures; although subject matter is often exchanged between groups, the practice of storytelling itself arises independently among even the most isolated peoples. Nor does any type of culture have a monopoly on narrative sophistication: the stories of hunter-horticulturalist societies are no less observant, insightful, or artful than those of agrarian or industrial societies.As with language, narrative takes the same basic form across cultures, which David Bordwell and Kristin Thompson define as "a chain of events in cause-effect relationship occurring in time." Given the preponderance of human agents in narrative, most narrative theorists would probably modify this barebones description to include character (usually understood to have a human psychology), goal-oriented action, and resolution. Frank Kermode, for example, defines the "proprieties" of narrative as "connexity, closure, and character," and John... (shrink)

Are epistemic reasons merely a species of instrumental practical reasons, making epistemic rationality a specialized form of instrumental practical rationality? Or are epistemic reasons importantly different in kind? Despite the attractions of the former view, Kelly (2003) argues quite compellingly that epistemic rationality cannot be merely a matter of taking effective means to one’s epistemic ends. I argue here that Kelly’s objections can be sidestepped if we understand epistemic reasons as instrumental reasons that arise in light of the aims (...) held by social collectives of which we are members, rather than being fixed by our own individual goals. This social version of epistemic instrumentalism would not be subject to counterexamples that point to the failure of individual people to possess desires or goals that would account for all of the epistemic reasons we find it natural to attribute to them. I conclude by comparing the proposed view to the alternative version of instrumentalism defended by Kornblith (1993). I argue that the social view I sketch here has one noteworthy advantage. It better accounts for the intuitive distinctness of our practical and epistemic reasons for belief in cases where flouting epistemic norms would better help us to achieve our own individual goals.

Digital apps using Bluetooth to log proximity events are increasingly supported by technologists and governments. By and large, the public debate on this matter focuses on privacy, with experts from both law and technology offering very concrete proposals and participating to a lively debate. Far less attention is paid to effective incentives and their fairness. This paper aims to fill this gap by offering a practical, workable solution for a promising incentive, justified by the ethical principles of non-maleficence, beneficence, (...) autonomy and justice. This incentive is a free phone optimised for running such app. (shrink)

The issue of what is proper to nature, or life itself, is central to critical accounts of biomedicine and its complex interrelations with social, political and economic forces. These engagements, namely biopolitical accounts of medical practices and ethical-political critiques of biomedical discourse, grapple with the indistinction between the political and biological that biomedicine enacts. Making a significant contribution to both literatures, Ed Cohen’s A Body Worth Defending argues that the emergence of the concept of biological immunity signals the entry of (...) politics into life itself and, as such, constitutes a concrete example of biopolitics. This article examines Cohen’s account of how the political becomes biological, and the view of life it assumes. Seeking to open up the question of biology, it draws on the work of Georges Canguilhem, and New Materialist accounts of matter–meaning entanglement, to offer a reading of knowledge and life, or politics and biology, as ontologically entangled.

This paper focuses on the phenomenon of forming one’s judgement about epistemic matters, such as whether one has some reason not to believe false propositions, on the basis of the opinion of somebody one takes to be an expert about them. The paper pursues three aims. First, it argues that some cases of expert deference about epistemic matters are suspicious. Secondly, it provides an explanation of such a suspiciousness. Thirdly, it draws the metaepistemological implications of the proposed explanation.

While possessing moral understanding is agreed to be a core epistemic and moral value, it remains a matter of dispute whether it can be acquired via testimony and whether it involves an ability to engage in moral reasoning. This paper addresses both issues with the aim of contributing to the current debates on moral understanding in moral epistemology and virtue ethics. It is argued that moral epistemologists should stop appealing to the argument from the transmissibility of moral understanding to (...) make a case for their favorite view of moral understanding. It is also argued that proponents of exemplarist moral theories cannot remain neutral on whether the ability to engage in moral reasoning is a necessary component of moral understanding. (shrink)

Some critical philosophers of race have argued that whiteness can be understood as a technology of affect and that white supremacy is comprised partly of unconscious habits that result in racialized perception. In an effort to deepen our understanding of the affective and bodily dimensions of white supremacy and the ways in which affective habits are socially produced, I look to insights from situated affectivity. Theorists in this field maintain that affective experience is not simply a matter of felt (...) inner states, but rather socially and environmentally embedded and fundamentally relational. Jan Slaby presents the concept of an ‘affective arrangement’ as a way to approach affectivity in terms of relational dynamics unfolding within a particular setting. Applying this concept to the societal level, Paul Schuetze introduces the notion of ‘affective milieu.’ I argue that these notions of ‘affective arrangement’ and ‘affective milieu,’ together with an organicist account of habit, can help to illuminate the workings of white supremacy in the United States. My proposed account highlights the extent to which white supremacy is an affective, bodily phenomenon and how racist habits are formed over the course of learning and ongoing affective engagement, in the context of various social settings. Crucially, these affective habits are fully bound up with habits of appraisal, interpretation, and judgment, and therefore inseparable from how subjects come to see and understand their world.

Purpose Cybersecurity in healthcare has become an urgent matter in recent years due to various malicious attacks on hospitals and other parts of the healthcare infrastructure. The purpose of this paper is to provide an outline of how core values of the health systems, such as the principles of biomedical ethics, are in a supportive or conflicting relation to cybersecurity. Design/methodology/approach This paper claims that it is possible to map the desiderata relevant to cybersecurity onto the four principles of (...) medical ethics, i.e. beneficence, non-maleficence, autonomy and justice, and explore value conflicts in that way. Findings With respect to the question of how these principles should be balanced, there are reasons to think that the priority of autonomy relative to beneficence and non-maleficence in contemporary medical ethics could be extended to value conflicts in health-related cybersecurity. Research limitations/implications However, the tension between autonomy and justice, which relates to the desideratum of usability of information and communication technology systems, cannot be ignored even if one assumes that respect for autonomy should take priority over other moral concerns. Originality/value In terms of value conflicts, most discussions in healthcare deal with the conflict of balancing efficiency and privacy given the sensible nature of health information. In this paper, the authors provide a broader and more detailed outline. (shrink)

This special issue of the Journal Law, Medicine & Ethics takes up the concern of informed consent, particularly in times of controversy. The dominant moral dilemmas that frame traditional bioethical concerns address medical experimentation on vulnerable subjects; physicians assisting their patients in suicide or euthanasia; scarce resource allocation and medical futility; human trials to develop drugs; organ and tissue donation; cloning; xenotransplantation; abortion; human enhancement; mandatory vaccination; and much more. The term “bioethics” provides a lens, language, and guideposts to the (...) study of medical ethics. It is worth noting, however, that medical experimentation is neither new nor exclusive to one country. Authors in this issue address thorny subjects that span borders and patients: from matters dealing with children and vaccination to the language and perception of consent. (shrink)

Over the last decades the problem of the existence of Byzantine philosophy has been posed in terms of the determination of its status, its function, and its subject matter. To a certain extent, this approach to Byzantine philosophy has been motivated by the increasing disciplinary autonomy reached by the other branches of what is nowadays called «medieval philosophy». A series of significant scholarly achievements over the last twenty years have contributed to the development of more-or-less well defined scholarly fields (...) of research concerning the medieval Latin, Arabic, and Jewish philosophical traditions. In regard to Byzantine philosophy the situation is much more complicated. In the first chapter of his La philosophie médiévale, Alain de Libera devotes his first words to the retarded scholarly development of the study of Byzantine philosophy. He claims that Byzantine philosophy has been mainly ignored and misunderstood, and has not been deeply studied. However, from the second half of the twentieth century one can find relevant and extremely important attempts to establish not only the basic features and developments, but the very existence of Byzantine philosophy. In this Forschungsbericht I shall attempt to reconstruct the scholarly debate on this topic, testing the main interpretive attitudes against some concrete cases of thinkers who lived in the area of the Eastern Roman Empire and who are labelled by most modern historians as «Byzantine».

Education theorists have emphasized that transformative learning is not simply a matter of students gaining access to new knowledge and information, but instead centers upon personal transformation: it alters students’ perspectives, interpretations, and responses. How should learning that brings about this sort of self-transformation be understood from the perspectives of philosophy of mind and cognitive science? Jack Mezirow has described transformative learning primarily in terms of critical reflection, meta-cognitive reasoning, and the questioning of assumptions and beliefs. And within mainstream (...) philosophy of mind, there has been a long-standing assumption that cognition and thought are brain-based, computational, disembodied processes that occur separately from emotion and affect. According to this view, selftransformation might be construed as the forging of new neural connections and the development of new cognitive “programs.” However, I will argue that the literature on embodiment and enactivism that has emerged in recent years offers us a different and more productive way to conceptualize the intended effects of transformative learning. From the standpoint of enactivism, the experience of transformative learning is thoroughly bound up with the cognitive shifts that it involves, and it also involves significant changes to the neurobiological dynamics of the living body. Moreover, personal transformation is not simply something that happens to subjects, but rather a process in which they are actively and dynamically engaged. In addition, this enactivist approach emphasizes that the learning process is fully embodied and fundamentally affective. From a phenomenological perspective, personal transformation can be understood as a pronounced alteration in cognitive-affective orientation; and from a neurobiological perspective, the development of new habits of mind can be understood as the formation of highly integrated patterns of bodily engagement and response. The upshot is that it is not just subjects’ brains that are altered over the course of transformative learning, but also their overall bodily and affective attunement to their surroundings. (shrink)

Historians and philosophers of science have examined the relationship between language and practice for a long time. Scholars have made important contributions to the field by attending to the social, cultural and economic contexts in which scientific paradigms are created and re-created. However, this article posits that while it is true that scientific practice and the artifacts they generate are both socially and discursively constructed and therefore, inextricable from the human contexts that produce them, these artifacts are not only texts (...) to be deciphered, but material things. This essay shows that the recalcitrant material dimension of my case study, a robotic moth, shapes the results of an experiment into the laws of aerodynamics in ways incommensurate with exclusively textual and/or rhetorical critiques.

Before philosophy, time was not problematized, it was a pure common-sensical matter. There were various experiences of time, and, accordingly, different words to name it. Whitehead’s solution of the temporal conundrum lies in the concept of “creative advance of (...) nature” that is systematically elucidated only in Process and Reality (1929) To understand the creative advance of nature, one needs to interpret the togetherness of its three aspects —creativity qua concrescence, efficacy qua transition, vision qua initial subjective aim—, and this provides us with the core meaning of time: (i) genuine novelty appears in the World, (ii) past events are, so to speak, ontologically memorized, and (iii) there is an upward trend in terms of “intensity” of events. These three complementary requirements refresh in their own way the Greek triple understanding of time: time is “aiôn,” lived duration (outside physical time) and destiny, but it is also “chronos,” causal time, and “kairos,” timeliness or the appropriate moment for action. -/- Michel Weber is Director of the Centre for Philosophical Practice (Brussels) and Adjunct Professor at the Department of Educational Foundations of the University of Saskatchewan. His current research program mainly addresses the Ayurvedic understanding of the anchoring of the mind in the body and of the expression of the body in the mind. (shrink)

This essay argues for two complementary theses, one pertaining to epistemology and the other to politics. First, unless philosophy adopts a radical empiricist standpoint and seeks the uttermost generalities, it cannot differentiate itself from yet another form of limited expertise and becomes useless. Second, both radical empiricism and imaginative pragmatism lead the philosopher towards the left end of the political spectrum, i.e., to a radically progressive politics.

This book traces how such a seemingly immutable idea as measurement proved so malleable when it collided with the subject matter of psychology. It locates philosophical and social influences reshaping the concept and, at the core of this reshaping, identifies a fundamental problem: the issue of whether psychological attributes really are quantitative. It argues that the idea of measurement now endorsed within psychology actually subverts attempts to establish a genuinely quantitative science and it urges a new direction. It relates (...) views on measurement by thinkers such as Holder, Russell, Campbell and Nagel to earlier views, like those of Euclid and Oresme. Within the history of psychology, it considers contributions by Fechner, Cattell, Thorndike, Stevens and Suppes, among others. It also contains a non-technical exposition of conjoint measurement theory and recent foundational work by leading measurement theorist R. Duncan Luce. (shrink)

Here I investigate the possibility of a phenomenological approach to Christianity, with the understanding that this would not be a matter of proposing an interpretation, but that such an “approach” would be able to lead directly to the heart of Christianity. I will say immediately that a phenomenology that would be able to undertake such a task is not the historical phenomenology that was born with Husserl. Only an ideal phenomenology that would become what is required would be able (...) to respond to our investigation. This ideal phenomenology is a phenomenology of life. (shrink)

We argue, in the spirit of some of Jean-Yves Jaffray’s work, that explicitly incorporating the information, however imprecise, available to the decision maker is relevant, feasible, and fruitful.

Film is a powerful medium that can influence audience’s perceptions, values and ideals. As filmmaking evolved into a serious art form, it became a powerful tool for telling stories that require us to re-examine our ideology. While it remains popular to adapt a literary novel or text for the screen, filmmakers have more freedom to pick and choose the stories they want to tell. This freedom allows filmmakers to explore narratives that might otherwise go unheard, which include stories that feature (...) marginal figures, such as serial killers, as sympathetic protagonists, which is what director Patty Jenkins achieves in her 2003 film Monster. Charlize Theron’s transformation into and performance as Aileen Wuornos, and Jenkins’s presentation of the subject matter, make this film an example of rogue cinema. In addition, Aileen Wuornos is portrayed as a clear example of the rogue character. This character trope frequently defies social standards, suffers from past trauma, is psychologically complex, and is often exiled. As a prostitute and social outcast, Aileen Wuornos exists on the fringes of society and rejects the hegemonic power structure and later heteronormativity of society, which makes her a rogue figure. While there are several aspects to consider when analyzing Jenkins’s film, my intention is to argue that this film is an example of rogue cinema because of its content. In order to accomplish this task, I examine Theron’s bodily transformation and her performance as Wuornos. Furthermore, I look at how Jenkins handles the depiction of romantic love and gendered violence and argue that her treatment of this content renders this film rogue. (shrink)

I argue that the coincidence of statue and matter is a special case of a common linguistic phenomenon: the use of partitive terms to individuate uses of non-count nouns (NCNs). By marking partitives and NCNs, we can easily account for the intuition that a statue and its matter are identical.

Science and philosophy still lack an overarching theory of consciousness. We suggest that a further step toward it requires going beyond the view of the brain as input-output machine and focusing on its intrinsic activity, which may express itself in two distinct modalities, i.e. aware and unaware. We specifically investigate the predisposition of the brain to evaluate and to model the world. These intrinsic activities of the brain retain a deep relation with consciousness. In fact the ability of the brain (...) to evaluate and model the world can develop in two modalities, implicit or explicit, that correspond to what we usually refer to as the unconscious and consciousness, and both are multilevel configurations of the brain along a continuous and dynamic line. Starting from an empirical understanding of the brain as intrinsically active and plastic, we here distinguish between higher cognitive functions and basic phenomenal consciousness, suggesting that the latter might characterize the brain’s intrinsic activity as such, even if at a very basic level. We proceed to explore possible impacts of the notion of intrinsic cerebral phenomenality on our understanding of consciousness and its disorders, particularly on the diagnosis and management of patients with disorders of consciousness.

What is mathematics about? Does the subject-matter of mathematics exist independently of the mind or are they mental constructions? How do we know mathematics? Is mathematical knowledge logical knowledge? And how is mathematics applied to the material world? In this introduction to the philosophy of mathematics, Michele Friend examines these and other ontological and epistemological problems raised by the content and practice of mathematics. Aimed at a readership with limited proficiency in mathematics but with some experience of formal logic (...) it seeks to strike a balance between conceptual accessibility and correct representation of the issues. Friend examines the standard theories of mathematics - Platonism, realism, logicism, formalism, constructivism and structuralism - as well as some less standard theories such as psychologism, fictionalism and Meinongian philosophy of mathematics. In each case Friend explains what characterises the position and where the divisions between them lie, including some of the arguments in favour and against each. This book also explores particular questions that occupy present-day philosophers and mathematicians such as the problem of infinity, mathematical intuition and the relationship, if any, between the philosophy of mathematics and the practice of mathematics. Taking in the canonical ideas of Aristotle, Kant, Frege and Whitehead and Russell as well as the challenging and innovative work of recent philosophers like Benacerraf, Hellman, Maddy and Shapiro, Friend provides a balanced and accessible introduction suitable for upper-level undergraduate courses and the non-specialist.

Article Summary. The epistemology of disagreement studies the epistemically relevant aspects of the interaction between parties who hold diverging opinions about a given subject matter. The central question that the epistemology of disagreement purports to answer is how the involved parties should resolve an instance of disagreement. Answers to this central question largely depend on the epistemic position of each party before disagreement occurs. Two parties are equally positioned from an epistemic standpoint—namely, they are epistemic peers—to the extent that (...) they have roughly equal access to the evidence and comparable intellectual resources. When one party is epistemically better positioned than the other—that is, when one is an epistemic superior—it is widely agreed that this party should retain their belief while the other party—the epistemic inferior—should revise their opinion in the direction of what the epistemic superior believes. Addressing the central question is a complex task when the disagreeing parties are epistemic peers. Three main answers can be distinguished. Conciliatory answers mandate that both parties revise—i.e. lower their confidence in—their beliefs upon the occurrence of peer disagreement. Steadfast answers allow both parties to retain their respective beliefs, thereby committing them to demote the epistemic position of the interlocutor. The third group of answers suggests that the solution to peer disagreement depends on whether either party is highly justified in holding their belief. If either party is highly justified, then it is rational that this party retains its view. If neither party is highly justified, both should revise. The epistemology of disagreement addresses further important questions such as: whether the occurrence of disagreement opens the doors to skepticism and/or relativism; what the consequences of epistemic disagreement on intellectual character are; what laypeople should do when experts disagree with each other; and whether disagreement among groups can be treated in the same way as disagreement among individuals.

Scientists working on the wave theory of light in the 19 th century took it for granted that there had to be a medium for the propagation of light waves. This medium was called the luminiferous [= “light carrying”] ether. One of the central questions about this medium concerned its state of motion. There were two options: (1) The ether is completely undisturbed by matter moving through it (stationary or immobile ether); (2) Matter drags along the ether in (...) its vicinity and/or in its interior (dragged-along ether). Stellar aberration provided the main argument for the first option (even though a special dragging effect in the case of transparent matter had to be built into the theory to account for refraction). Polarization provided the main argument for the second option. These two options and the arguments pro and con will be explained in more detail below. (shrink)

The popular conception of the Renaissance as a culture devoted to order and perfection does not account for an important characteristic of Renaissance art: many of the period's major works, including those by da Vinci, Erasmus, Michelangelo, Ronsard, and Montaigne, appeared as works-in-progress, always liable to changes and additions. In Perpetual Motion, Michel Jeanneret argues for a sixteenth century swept up in change and fascinated by genesis and metamorphosis. Jeanneret begins by tracing the metamorphic sensibility in sixteenth-century science and (...) culture. Theories of creation and cosmology, of biology and geology, profoundly affected the perspectives of leading thinkers and artists on the nature of matter and form. The conception of humanity (as understood by Pico de Mirandola, Erasmus, Rabelais, and others), reflections upon history, the theory and practice of language, all led to new ideas, new genres, and a new interest in the diversity of experience. Jeanneret goes on to show that the invention of the printing press did not necessarily produce more stable literary texts than those transmitted orally or as hand-printed manuscripts—authors incorporated ideas of transformation into the process of composing and revising and encouraged creative interpretations from their readers, translators, and imitators. Extending the argument to the visual arts, Jeanneret considers da Vinci's sketches and paintings, changing depictions of the world map, the mythological sculptures in the gardens of Prince Orsini in Bomarzo, and many other Renaissance works. More than fifty illustrations supplement his analysis. (shrink)

Einstein’s 1905 paper on special relativity suggests that relativistic mechanics is simply a matter of adjusting Newton’s to make it Lorentz invariant. Einstein, for instance.

In 1907, Einstein set out to fully relativize all motion, no matter whether uniform or accelerated. After five failed attempts between 1907 and 1918, he finally threw in the towel around 1920, setting himself a new goal. For the rest of his life he searched for a classical field theory unifying gravity and electromagnetism. As he struggled to relativize motion, Einstein had to readjust both his approach and his objectives at almost every step along the way; he got himself (...) hopelessly confused at times; he fooled himself with fallacious arguments and sloppy calculations; and he committed what he later allegedly called the biggest blunder of his career: he introduced the cosmological constant. There is a very uplifting moral to this somber tale. Although Einstein never reached his original destination, the harvest of his thirteen-year odyssey is quite impressive. First of all, what is left of absolute motion in general relativity is far more palatable than absolute motion in special relativity or Newtonian theory. And general relativity does seem to eliminate absolute space. More importantly, from a modern physics point of view, Einstein produced a spectacular new theory of gravity based on what he called the equivalence principle. This principle says that inertial and gravitational effects are due to one and the same structure, the inertio-gravitational field, which in Einstein’s theory is represented by a metric tensor field. In addition to laying the foundations of this theory, Einstein, among other things, launched relativistic cosmology, suggested the possibility of gravitational waves, gave the first sensible definition of a space-time singularity, and caught on to the intimate connection between general covariance and energy-momentum conservation, an example of the general connection between symmetries and conservation laws of Noether’s theorems. These results more than make up for the—at least by the standards of modern philosophy of science—rather opportunistic way in which they were obtained.. (shrink)

In the course of his work on optics and electrodynamics in systems moving through the ether, the 19th-century medium for light waves and electric and magnetic fields, Lorentz discovered and exploited the invariance of the free-field Maxwell equations under what Poincaré later proposed to call Lorentz transformations. To account for the negative results of optical experiments aimed at detecting the earth’s motion through the ether, Lorentz, in effect, assumed that the laws governing matter interacting with light waves are Lorentz (...) invariant as well. Like Lorentz, Einstein first encountered the Lorentz transformations in electrodynamics. Unlike Lorentz, for whom the transformation merely provided convenient mathematical substitutions, but like Poincaré, Einstein recognized that the Lorentz-transformed quantities are the measured quantities for the moving observer. More importantly, Einstein recognized that the Lorentz invariance of all physical laws had nothing to do with electrodynamics per se, but reflected the kinematics in a new relativistic space-time, to be named after Minkowski who worked out its geometry a few years later.

Scientists working on the wave theory of light in the 19th century took it for granted that there had to be a medium for the propagation of light waves. This medium was called the luminiferous [= “light carrying”] ether. One of the central questions about this medium concerned its state of motion. There were two options: (1) The ether is completely undisturbed by matter moving through it (stationary or immobile ether); (2) Matter drags along the ether in its (...) vicinity and/or in its interior (dragged-along ether). Stellar aberration provided the main argument for the first option (even though a special dragging effect in the case of transparent matter had to be built into the theory to account for refraction). Polarization provided the main argument for the second option. These two options and the arguments pro and con will be explained in more detail below. (shrink)

The transformations undergone by research and science in the name of the so called "knowledge economy" cover the decisions of scientific policies and the "management" of research, and also the meaning of scientific activities (devoted to innovation) and even more fundamentally the very structure of the sciences (transformed to technosciences). The science that is contributing to capitalist competitiveness (and to the current economic crisis) is not the same as that which would be able to contribute "to the conception and democratic (...) carrying out of another form of globalization and another European project". However, this is not self-evident, and it needs to be thought about since it is not simply a matter of returning to the science of the 20th century that opened the way to technoscience. (shrink)

Postural instability and balance impairment are disabling symptoms in patients with acute unilateral peripheral vestibular hypofunction. Vestibular rehabilitation is known to improve the vestibular compensation process, but its effect on posture recovery remains poorly understood, little is known about when VR must be done, and whether the degree of vestibular loss matters is uncertain. We analyzed posture control under static and dynamic postural tasks performed in different visual conditions [eye open ; eyes closed ; and optokinetic stimulation] using dynamic posturography. (...) Non-linear analyses of the postural performance were performed in two groups of patients with UVH subjected to the same VR program based on the unidirectional rotation paradigm and performed either early or later after vertigo attack. Distribution of the angular horizontal vestibulo-ocular reflex gain values recorded on the hypofunction side before rehabilitation differentiated two distinct sub-groups with aVOR gains below or above 0.20. The postural performance of the four sub-groups of patients with UVH tested before VR showed significantly altered postural parameters compared with healthy controls. Greater instability, higher energy to control posture, larger sway without feedback corrections, and lower time of automatic control of posture were observed in static conditions. The four sub-groups recovered near-normal postural performance after VR in the EO and EC conditions, but still exhibited altered postural performance with optokinetic stimulation. In dynamic posturography conditions and before VR, the percentage of patients able to perform the postural tasks with EC and optokinetic stimulation was significantly lower in the two sub-groups with aVOR gain <0.20. After VR, the improvement of the postural parameters depended on the stage of rehabilitation and the degree of vestibular hypofunction. The best balance function recovery was found in the sub-group with early VR and pre-rehabilitation aVOR gain above 0.20, the worst in the sub-group with late rehabilitation and aVOR gain below 0.20. These differences were seen when the vestibular input remains the main sensory cue to control balance, that is, on unstable support without vision or altered visual motion cues. These findings extend to dynamic balance recovery the crucial roles of early rehabilitation and degree of vestibular hypofunction which we have already highlighted for vestibulo-ocular reflex recovery.
