There is a striking difference between the methodology of the young Einstein and that of the old. I argue that Einstein’s switch in the late 1910s from a moderate empiricism to an extreme rationalism should at least in part be understood against the background of his crushing personal and political experiences during the war years in Berlin. As a result of these experiences, Einstein started to put into practice what, drawing on Schopenhauer, he had preached for years, namely to use (...) science as his means of escaping from “the merely personal.” Whatever the exact sources of Einstein’s about-face, the older man has left us with a highly misleading picture of how the younger man achieved the successes that we still celebrate today. This has had a harmful influence on theoretical physics. If the young Einstein’s successes are any guide as to how successful theoretical physics is done, close adherence to general features of the empirical data is much more and mathematical elegance is much less important than the old Einstein wanted us to believe.

An exciting and highly original examination of the practices of truth-telling and speaking out freely (parr?sia) in ancient Greek tragedy and philosophy. Foucault discusses the difficult and changing practices of truth-telling in ancient democracies and tyrannies and offers a new perspective on the specific relationship of philosophy to politics.

The history of research on pseudoalleles, closely linked genes that have similar functions, is rich and complex. Because pseudoalleles’ proximity on the chromosome makes their distinction by the complementation tests traditionally used by geneticists difficult, and because they have similar functions, they were initially often considered as allelic forms of the same gene, hence their name. The Hox cluster is an emblematic example of a pseudoallelic gene complex. The first observations of pseudoalleles were made very early but remained puzzling until (...) a simple model explaining their formation and characteristics emerged in the middle of the 1930s. This model suggested that pseudoalleles originated by gene.. (shrink)

An ode to Schopenhauer by one of France's most famous living authors.

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)

The image of the “mirror” (鏡kagami) appears frequently in the philosophical texts of Nishida Kitaro (西田幾多郎1870-1945), where it assumes various functions. Mirror references first occur in meditations on the philosophies of Josiah Royce (1855-1916) and Henri Bergson (1859-1941). The most fascinating evocation here corresponds to the idea of a “self-enlightening mirror”, used to probe the philosophical ground for self-illumination. This idea seems to point back to Buddhist meaning that intervenes in Japanese intellectual history. We take this as our warrant for (...) establishing here, firstly, how Nishidean philosophical speculation can be critically related to the thought of Dogen (道元1200-1253); and, secondly, in what sense it has stimulated some contemporary approaches in Japanese philosophy (for example, those of Nitta, Ohashi, and Sakabe).

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.

In the Fall of 1900, Frederick T. Trouton started work on an ingenious experiment in his laboratory at Trinity College in Dublin. The purpose of the experiment was to detect the earth’s presumed motion through the ether, the 19th century medium thought to carry light waves and electric and magnetic fields. The experiment was unusual in that, unlike most of these so-called ether drift experiments, it was not an experiment in optics. Trouton tried to detect ether drift by charging and (...) discharging a capacitor in a torsion pendulum at its resonance frequency, which he hoped would set the system oscillating. (shrink)

We know very little about the history of the Belgian contribution to the European Construction from 1945 to the present. That wilt say that the historiography has to fill a gap, more particularly in the field of therole of leading men and pressure groups. The case of the European League for Economic Cooperation is a good one because it shows the determinant influence of a man and its friends over the « attentive opinion», not only in Belgium but also in (...) other European countries, at the beginning of the cold war about the so called European Challenge. But the birth and development of the ELEC show also that national problems could deeply influence an international initiative. The opposition of the Socialists in Belgium considerably hindered the international issue of the ELEC. (shrink)

La rencontre de Karl Barth permet à Henri Bouillard de manifester, d'une part, que la pensée barthienne évolue, et que, d'autre part, elle fait abstraction de l'expérience humaine et de son ouverture au surnaturel. Cela permet au théologien français d'établir que la relation de l'homme à Dieu est à la fois oeuvre de Dieu et oeuvre de l'homme, et en particulier que la connaissance de Dieu est une connaissance révélée et en même temps une connaissance naturelle, que l'analogie de la (...) foi ne va pas sans l'analogie de l'être, et que la morale et la politique sont hétéronomes dans leur inspiration et autonomes dans leur détermination.

Nous vivons dans un monde problématique, sans certitudes fixes. Désormais l’expérience est celle d’un flux héraclitéen. Nous sommes devenus des marins. Les intégristes voudraient jeter l’ancre en pleine tempête et les relativistes se laisser aller au fil du courant. La seule issue est d’apprivoiser le devenir dans un processus de problématisation, dont la démarche scientifique fournit le paradigme, processus qui articule doutes et certitudes sans remettre tout en question à chaque fois et qui permet des résultats provisoires certes mais suffisamment (...) assurés pour progresser. Il faut donc concevoir l’éducation comme problématisation. Ce qui implique de doter les jeunes de nouveaux types de repères : boussole et cartes avec lesquels ils pourront s’orienter eux-mêmes sur le fond d’un héritage, d’une expérience transmise. Une philosophie de l’éducation inspirée de la problématologie de John Dewey et de Michel Meyer, permet un autre regard sur l’évolution des normes éducatives, sur les schèmes qui les sous-tendent, sur le savoir et la culture scolaire, sur l’émancipation.

The two major options on which the current debate on the interpretation of quantum mechanics relies, namely realism and empiricism, are far from being exhaustive. There is at least one more position available, which is metaphysically as agnostic as empiricism, but which shares with realism a committment to considering the structure of theories as highly significant. The latter position has been named transcendentalism after Kant. In this paper, a generalized version of Kant's method is used. This yields a reasoning that (...) one is entitled to call a transcendental deduction of some major formal features of quantum mechanics. (shrink)

Por Laura Fraga de Almeida Sampaio, tradutora do livro A aula inaugural, que Foucault pronunciou ao assumir a cátedra vacante no Collège de France pela morte de Hyppolite, pode ser considerada um texto de ligação entre suas obras, datadas dos anos 60, como História da loucura, As palavras e as coisas, A arqueologia do saber, centradas predominantemente na análise das condições de possibilidade das ciências humanas, e as que se seguiram a maio de 68, como Vigiar e punir, voltados ao (...) exame da microfisica do poder. Foucault desvenda a relação entre as práticas discursivas e os poderes que as permeiam. Ao perceber os diversos procedimentos que cerceiam e controlam os discursos da sociedade, o autor comprova que "o discurso não é simplesmente aquilo que traduz as lutas ou os sistemas de dominação, mas aquilo pelo que se luta, o poder de queremos nos apoderar". Na segunda parte do texto, Foucault anuncia a direção em que prosseguirá suas investigações no decorrer dos cursos no Collège de France, apontando para o que denomina o "conjunto crítico" e o "conjunto genealógico" e lança o projeto de estudo das interdições que atingem o discurso da sexualidade. A este trabalho dedicará muitos anos, após a publicação do primeiro volume da História da sexualidade, em 1976: A vontade de saber (uso dos prazeres, vol.2, O cuidado de si, vol, 3, ambos de 1984).

Que comprenons-nous du monde dans lequel nous vivons? Alors que celui-ci est entièrement pénétré par les technologies numériques, alors qu'elles modifient en profondeur nos pratiques intellectuelles, nous manquons singulièrement de moyens pour les comprendre. Puisque les machines et les algorithmes constituent une partie de notre réalité, il est de première importance, non seulement de savoir utiliser les outils numériques, mais, plus profondément, de s'approprier ce nouvel univers symbolique auquel nous appartenons tous.

Toute science, admet-on, commence par détacher un objet en le rendant indépendant des sujets et des situations. Mais cette conception étroite de la connaissance scientifique laisse subsister des zones d'ombre. La conscience n'est pas un objet. Elle est ce sans quoi rien ne pourrait être pris pour objet. La conscience n'est pas détachable des sujets, car elle s'identifie à ce qui est vécu par un sujet. De façon analogue, en physique quantique, un phénomène n'est pas dissociable de son contexte expérimental, (...) car il s'identifie à ce qui se manifeste à grande échelle au laboratoire. Que faire pour ne pas laisser ces cas extrêmes de côté? Généraliser la méthode scientifique. Ne plus la borner à définir et à caractériser des objets, mais l'étendre à la coordination directe des expériences. Telle est la révolution de pensée qu'il faut accomplir pour résoudre, ou plutôt dissoudre, deux questions-limites de la science : le problème de l'origine de la conscience et le paradoxe du "chat de Schrödinger" en physique quantique.

Les sciences de la nature construisent des symboles spécifiques pour saisir adéquatement la réalité de la nature. La puissance de leurs symboles est telle que la pensée scientifique déborde ce réel, l’anticipe, le reconstruit et finalement le réalise et le prolonge sur le plan technique. Mais quel est le point de départ de la symbolisation scientifique? Comment peut-elle, couplée à la technique, réaliser la réalité même de la nature? Enfin, le langage spécifique des sciences de la nature peut-il s’autonomiser par (...) rapport aux langues « naturelles », relatives à des groupes humains et parlées spontanément? L’enjeu consiste à montrer, tout à la fois, les limites et la puissance des symboles des sciences de la nature que sont la physique et la chimie. (shrink)

The Nietzschean inspiration in Reiner Schürmann’s thinking is considerable, and he acknowledged it openly. Indeed, in a number of ways he presents Nietzsche as a forerunner of most of his own themes: the pluralizing of the origin, the relativizing of law, the negation of every dominant arche, the refusal of goals or of conscious finality, the primacy of praxis over theoria, and the affirmation of ontological play, among others. Because his more hidden aim is to find a common ground between (...) Heidegger and Nietzsche, it is difficult for him to give an account of Heidegger’s deconstruction of Nietzsche. But he utilizes a strategy that avoids openly disagreeing with Heidegger, which he rarely does. The strategy consists of arguing that Nietzsche’s fundamental concepts as interpreted by Heidegger do not actually refer to Nietzsche, but merely to modern technology. Heidegger’s texts on Nietzsche deal formally with Nietzsche, but materially with Technology. “Heidegger substitutes within the History of Being the technological moment for the Nietzschean moment.” It is not certain that this reading is compatible with Heidegger’s position on Nietzsche as an independent stage of metaphysics, and as the penultimate degree in the unfolding of the will to will. Schürmann jumps directly to the ultimate stage, in order, as it were, to “protect” Nietzsche from the deconstructive reading. He never comes to grips with the Heideggerian reading, because for him the Nietzschean concepts are used merely to describe the essence of Technology. Therefore, Schürmann simply leaves out all the “positive” or phenomenological interpretations of the Will to Power as affectivity or of the Eternal Return as “instant of vision” in Nietzsche I. He either ignores or does not see the doubleness of Nietzschean concepts for Heidegger insofar as they are both pre-technological and pre-phenomenological. (shrink)

The mechanisms by which bacteria adapt to changes in their environment involve transcriptional regulation in which a transcriptional regulator responds to signal(s) from the environment and regulates (positively or negatively) the expression of several genes or operons. Some of these regulators exert a positive feedback on their own expression. This is a necessary (although not sufficient) condition for the occurrence of multistationarity. One biological consequence of multistationarity may be epigenetic modifications, a hypothesis unusual to microbiologists, in spite of some well-known (...) epigenetic modifications in bacteria. We propose here that the occurrence of mucoidy in the opportunistic pathogen Pseudomonas aeruginosa, which is currently attributed to mutations only, may also be an epigenetic modification. A theoretical approach using a generalised logical analysis lends credit to this hypothesis and suggests experiments to ascertain it. (shrink)
