The particle internal clock conjectured by de Broglie in 1924 was investigated in a channeling experiment using a beam of ∼80 MeV electrons aligned along the 〈110〉 direction of a 1 μm thick silicon crystal. Some of the electrons undergo a rosette motion, in which they interact with a single atomic row. When the electron energy is finely varied, the rate of electron transmission at 0° shows a 8% dip within 0.5% of the resonance energy, 80.874 MeV, for which the (...) frequency of atomic collisions matches the electron’s internal clock frequency. A model is presented to show the compatibility of our data with the de Broglie hypothesis. (shrink)

continent. 2.2 (2012): 152–154 Levi R. Bryant. The Democracy of Objects . Ann Arbor, MI: Open Humanities Press. 2011. 316 pp. | ISBN 9781607852049. | $23.99 For two decades post-anarchism has adopted an epistemological point of departure for its critique of the representative ontologies of classical anarchism. This critique focused on the classical anarchist conceptualization of power as a unitary phenomenon that operated unidirectionally to repress an otherwise creative and benign human essence. Andrew Koch may have inaugurated this trend in (...) 1993 when he wrote his influential paper entitled “Post-structuralism and the Epistemological Basis of Anarchism.” Koch’s paper certainly laid some of the important groundwork for post-anarchism’s continual subsumption of ontology beneath the a priori of an epistemological orientation, and his work continues to be cited as an early and important venture into post-anarchist philosophy. The problem is that Koch could not conceive of an anti-essentialist and autonomous ontological system, one not subject to regulation or representation by the human mind. Consequently, he was forced to assert a subjectivist claims-making ego as the foundation of a post-structuralist anarchist politics. Saul Newman was indebted to this heritage insofar as he also posited the ego (extrapolated from the writings of Max Stirner) and the subject (extrapolated from Jacques Lacan’s oeuvre ) as the paradoxical ‘outside’ to power and representation. Todd May fell into a similar trap in his book The Political Philosophy of Post-structuralist Anarchism when he wrote that “[m]etaphysics [...] partakes of the normativity inhabiting the epistemology that provides its foundations.” 1 Whereas Newman’s approach did not necessarily foreclose the possibility of metaphysics—at least to the extent that he began with the subject of the Lacanian tradition (wherein the subject is believed to be radically split between thinking and being)—May completely foreclosed the possibility of any escape from the reign of the epistemological. There laid the impasse of yesterday’s post-anarchism. This impasse at the heart of the project of post-anarchism has forced Koch, Newman, May, and many others, to come to similar conclusions about the place of ontology in post-anarchist scholarship. The post-anarchists have all formulated a response strikingly similar to Koch’s argument that any representative ontology ought to be dismantled and dethroned in favour of “a conceptualization of knowledge that is contingent on a plurality of internally consistent episteme .” 2 By dismissing all ontologies as suspiciously representative and as incessantly harbouring a dangerous form of essentialism, post-anarchists have overlooked the privilege that they have placed on the human subject, language, and discourse, at the expense of the democracy that the human subject shares with other animals, objects, and beings in the world. This epistemological characterization of post-anarchism has held sway for far too long. It is not by chance that post-anarchism, as a concept, was first formulated by Hakim Bey as an “ontological anarchism,” 3 and subsequently repressed by the canon of post-anarchist authors. Perhaps Bey’s ontological anarchism also lacked the ‘rigour’ required of today’s scholarly audience and for these two reasons (at least) he has received very little credit for his inaugurating efforts into post-anarchism. In any case, I want to challenge this reluctance and revive the roots of post-anarchism. Levi Bryant gives us a reason to believe that we can achieve the promise of Bey’s ontological anarchism without sacrificing the scholarly standard of rigour. Levi Bryant’s newest open-access book, The Democracy of Objects , is a tour de force . His book challenges post-anarchists to take their radical critique of representation a step further by questioning the “hegemony that epistemology currently enjoys in philosophy.” Bryant maintains that post-structuralism, and radical anti-humanisms, only appear to reject the subject as the locus of political agency. Their rejection is actually more of a disavowal, a replacement of the human subject with the equally human order of language or discourse. What post-structuralism attempts to elucidate is the manner in which the subject is colonized by the Other of language, discourse and social relations. What here appears as a movement away from the determining subject of humanism and existentialism is only replaced with the determining apparatuses of structures as they are conceived by astute analysts of political culture. Post-structuralism thus re-enters the anthropocentric discourse to the extent that the cultural analyst believes himself capable of conceiving the determinative structures of society. In contradistinction to the claims of post-structuralism and post-anarchism, the role of the ontologist is not to suture the gap between epistemology and the real but to de-suture it, as Bryant puts it: “[o]ntology does not tell us what objects exist, but that objects exist, that they are generative mechanisms.” Above all else, the role of ontology, for post-anarchists, ought to be a real de-centering of the subject in relation to other objects in the non-human world such that the subject becomes conceived as one object among others within a living democracy of equality. This inevitably leads to the conclusion that objects exist whether or not the subject or analyst is there to represent them: they represent themselves and are autonomous from our dictation, just as each object finds its autonomy in relation to other objects. Ontology must now be distinguished from representation. We must shift the terms of the debate and interrogate the hegemony that epistemology has been afforded within post-anarchist philosophy. At least two possibilities are now permitted. On the one hand, one could intervene into the reigning mode of philosophy, namely epistemology, by latching onto concepts from meta-ethical philosophy. Meta-ethics allows one to easily separate the ontological from the epistemological and to answer very particular questions about each in order to formulate an overarching meta-ethical position. 4 Post-anarchism is particularly adept at this task because of its resounding ability to frame itself as an ethical political philosophy in relation to the strategic political philosophy of classical Marxism. On the other hand, Bryant argues that “[p]erhaps the best way to defeat [the privilege currently held by epistemology] is to shift the terms of debate.” Shifting the terms of debate is also something that post-anarchists have been very good at doing. Thus, instead of asking the question ‘how do representative ontological systems harbour concealed epistemological orientations toward the political?’ one might ask ‘ do epistemological orientations toward the political always harbour representative and subject-centred ontological systems?” The genius of Bryant’s book rests in its ability to convincingly argue for the radical autonomy of being and of objects. This claim speaks to some of the most compelling theories of the political in anarchist and marxist political philosophy (for instance, hegemony, representation, democracy, and so on) and it re-stages the political drama of our times across a much wider terrain. The fallacy of strategic political philosophy in the Marxist tradition, as Todd May quite correctly points out, is that it remains committed to a concept of power that is unitary in its analysis, unidirectional in its influence, and utterly repressive in its effect. Similarly, Bryant’s ontology allows one to argue that there is a fallacy that occurs “whenever one type of entity is treated as the ground or explains all other entities.” Whereas May’s post-structuralist anarchism moved away from the fallacy of the unitary analysis of power, whereby subjects are constituted by the influence of a single site of power, it nonetheless remained committed to a tactical political philosophy which is monarchical in the final analysis . It remains monarchical to the extent that the human world, the world of epistemology, is treated as the yardstick of democracy. Bryant’s argument is quite instructive: “[w]hat we thus get is not a democracy of objects or actants where all objects are on equal ontological footing [...] but instead a monarchy of the human in relation to all other beings.” The real fallacy is thus not against strategic political philosophy but philosophy itself and the way it has played out over so many centuries. “The epistemic fallacy,” writes Bryant, “consists in the thesis that proper ontological questions can be fully transposed into epistemological questions.” The point that Bryant is making relates to the way ontology is today always reduced to an epistemology and thereby loses its significance as a philosophical question. This book should be applauded for its novelty and its thesis ought to be taken seriously by post-anarchists today. Because of this book, and the attendant post-continental movement that is being called ‘speculative realism,’ we can now distinguish three stages in the life of post-anarchism. First, we can deduce what Süreyya Evren has described as its ‘introductory period.’ The introductory period of post-anarchism is defined by its inability to side-step the ontological problem in the literature of classical anarchism. During this period, post-anarchism needed to distinguish itself from classical anarchism while nonetheless remaining committed to its ethical project. The second period overcomes the problem of the separation of post-anarchism from classical anarchism by re-reading the classical tradition as essentially post-anarchistic. Some of the critiques of post-anarchism—especially that from Cohn & Wilbur 5 —are included into this period insofar as post-anarchism, for them, was always already anarchism. Whereas the first and second phases have included only explicitly anarchist literature under their rubric of worthwhile investigation, in the third period this no longer holds true. To be certain, the second period permitted the incorporation of post-structuralist literature into post-anarchist discussions (but always with a certain amount of reservation). This third period, the one that is to come—the one that is already here if only we would heed its call—will not take such care with attempts at identification or canonization. Indeed, post-anarchism is already here, like a seed beneath the snow, waiting to be discovered. Levi Bryant teaches us that the third period is already here: and yet where is it? NOTES 1) Todd May.

Parce que le temps est une question de pouvoir, la nuit en est également une. À notre collègue Marc Bessin En 2017, le numéro de _Conflits et Cultures _dirigé par le collectif CANDELA avait « pour ambition de démontrer la pertinence de ce champ de recherche [les sciences sociales du politique de la nuit] en constitution » (2017, p. 27).

The dossier of decrees concerning the Deceleans and the Demotionidae of Athens presents fascinating problems and has attracted plentiful discussion. For a long time there has been a division between the view of Wilamowitz and his followers, that the Demotionidae were a phratry and the Deceleans a privileged genos within it, and that of Wade–Gery refined by Andrewes, that the Deceleans were a phratry and the Demotionidae a privileged genos within it.3 Each of these interpretations gave rise to problems; and (...) since the work of Bourriot and Roussel on the gene there has been a reluctance to believe in gene as aristocratic clans able to control their phratries. Recently Hedrick has argued that the Demotionidae were the phratry and the Deceleans the members of the deme of Decelea; and Lambert has argued that the Demotionidae were the phratry and the Deceleans a genos–like body which formed a semi–independent group within the phratry and which in these decrees was extending its independence further. These interpretations also give rise to problems: in this paper I attempt to continue the debate and to show that an interpretation on Wade–Gery′s lines is after all the most likely to be right.

The ability to learn complex tasks is fundamental to being human. Rahman and Gray examine this process in the context of learning to play a simple video game, using a tool called SpotLight to examine the low‐level process of skill and strategy improvements during this process.

Alain Badiou has claimed that Quentin Meillassoux's book After Finitude (Bloomsbury, 2008) "opened up a new path in the history of philosophy." And so, whether you agree or disagree with the speculative realism movement, it has to be addressed. Lacanian Realism does just that. This book reconstructs Lacanian dogma from the ground up: first, by unearthing a new reading of the Lacanian category of the real; second, by demonstrating the political and cultural ingenuity of Lacan's concept of the real, and (...) by positioning this against the more reductive analyses of the concept by Slavoj Zizek, Alain Badiou, Saul Newman, Todd May, Joan Copjec, Jacques Ranciere, and others, and; third, by arguing that the subject exists intimately within the real. Lacanian Realism is an imaginative and timely exploration of the relationship between Lacanian psychoanalysis and contemporary continental philosophy. (shrink)

Despite their conceptual allergy to vegetal life, philosophers have used germination, growth, blossoming, fruition, reproduction, and decay as illustrations of abstract concepts; mentioned plants in passing as the natural backdrops for dialogues, letters, and other compositions; spun elaborate allegories out of flowers, trees, and even grass; and recommended appropriate medicinal, dietary, and aesthetic approaches to select species of plants. In this book, Michael Marder illuminates the vegetal centerpieces and hidden kernels that have powered theoretical discourse for centuries. Choosing twelve botanical (...) specimens that correspond to twelve significant philosophers, he recasts the development of philosophy through the evolution of human and plant relations. A philosophical history for the postmetaphysical age, The Philosopher's Plant reclaims the organic heritage of human thought. With the help of vegetal images, examples, and metaphors, the book clears a path through philosophy's tangled roots and dense undergrowth, opening up the discipline to all readers. (shrink)

Der Begriff der Autorität verortet sich im 20. Jahrhundert in einer komplexen Matrix zwischen zeitgeschichtlichem Problembewusstsein, »konservativem« Denken und politischer Theoriebildung. Drei Perspektiven kennzeichnen die Rede von Autorität im 20. Jahrhundert: erstens die vermeintliche Krise einer vormals fraglosen Gültigkeit, zweitens der Versuch genealogischer Rückversicherung durch Versatzstücke der Tradition und drittens die Behauptung, Autorität könne als Grundbegriff politischer Theoriebildung und insbesondere demokratischer Ordnungen dienen. Der Sammelband analysiert das Konzept der Autorität entsprechend entlang der drei Dimensionen der Krise, der Konstruktion und der (...) Konjunktur. Der Band arbeitet dabei interdisziplinär: Vereint werden historische, literaturwissenschaftliche und philosophische Ansätze. (shrink)

The sense of agency is the experience of being the origin of a sensory consequence. This study investigates whether contextual beliefs modulate low-level sensorimotor processes which contribute to the emergence of the sense of agency. We looked at the influence of causal beliefs on ‘intentional binding’, a phenomenon which accompanies self-agency. Participants judged the onset-time of either an action or a sound which followed the action. They were induced to believe that the tone was either triggered by themselves or by (...) somebody else, although, in reality, the sound was always triggered by the participants. We found that intentional binding was stronger when participants believed that they triggered the tone, compared to when they believed that another person triggered the tone. These results suggest that high-level contextual information influences sensorimotor processes responsible for generating intentional binding. (shrink)

Now in a third edition, Introduction to Philosophy: Classical and Contemporary Readings is a highly acclaimed, topically organized collection that covers five major areas of philosophy--theory of knowledge, philosophy of religion, philosophy of mind, freedom and determinism, and moral philosophy. Editor Louis P. Pojman enhances the text's topical organization by arranging the selections into a pro/con format to help students better understand opposing arguments. He also includes accessible introductions to each chapter, subsection, and individual reading, a unique feature for an (...) anthology of this depth. While the book focuses on a compelling sampling of classical material--including selections from Plato, Aristotle, Descartes, Locke, Berkeley, Hume, and Kant--it also incorporates some of philosophy's best twentieth-century and contemporary work, featuring articles by Bertrand Russell, Richard Taylor, John Searle, Thomas Nagel, and others. This third edition contains an expanded glossary, more extensive section introductions, and twelve new selections: Karl Popper: "Epistemology without a Knowing Subject" Richard Rorty: "Dismantling Truth: Solidarity Versus Objectivity" Daniel Dennett: "Postmodernism and Truth" Bruce Russell: "The Problem of Evil: Too Much Suffering" David Chalmers: "Against Materialism: Can Consciousness Be Reductively Explained?"

How do gym-goers who are normally not inclined to resort to appearance- and performance-enhancing drugs (APEDs) progressively normalize their use? Based on data collected through a year and a half of participant observation in a gym and thirty semi-directive interviews with practitioners with varying profiles in French-speaking Switzerland, this article examines the evolution of practitioners’ relations with APED use by articulating various levels of analysis. Associated with social vulnerabilities, the progressive normalization of APED use is concomitant with the “conversion” to (...) bodybuilding. Our results show the extent to which and under what conditions interactions within the layout of gyms can influence practices. From refusal to normalization, our results suggest that APEDs and the associated beliefs coincide with career stages, which we aim to bring to light here. (shrink)

In this paper we analyse some questions concerning trees on κ, both for the countable and the uncountable case, and the connections with Cohen reals. In particular, we provide a proof for one of the implications left open in [6, Question 5.2] about the diagram for regularity properties.

This paper advances the research on personalization of political communication by investigating whether this process of focusing on politicians instead of political issues plays a role on Twitter. Results of a content analysis of 5,530 tweets posted in the run-up to the German federal election provide evidence that Twitter communication refers more often to politicians than to issues. However, tweets containing personal characteristics about political leaders play only a marginal role. When distinguishing among different groups of actors on Twitter (journalists, (...) politicians, citizens), we find that citizens focus more on candidates than do journalists or politicians. Investigating the impact of a televised debate on Twitter communication, we observe that this person-centered event puts the focus on individual politicians instead of issues. (shrink)

This article aims to read feminist new materialisms (Barad), together with ‘postulated’ linguistic or cultural primacy of Queer Theory (Butler), to show how both are engaged in similar critical-ethical endeavours. The central argument is that the criticism of Barad and new materialisms misses Butler’s materialistic insights due to a narrow interpretation of Butler's alleged social-constructivist position. There is, therefore, a specific focus on where they both make similar ethical appeals. Moreover, the article relies on Adorno's negative dialectic to highlight an (...) interpretation of Barad and Butler as being part of the same dialectical movement, in which materialism and idealism fluctuate in their mutual criticisms, thus continuing the procession towards 'new knowledge' and emancipation, or freedom, through their motions back and forth.

The Type VI secretion system is a multiprotein and mosaic apparatus that delivers protein effectors into prokaryotic or eukaryotic cells. Recent data on the enteroaggregative Escherichia coli T6SS have provided evidence that the TssA protein is a key component during T6SS biogenesis. The T6SS comprises a trans-envelope complex that docks the baseplate, a cytoplasmic complex that represents the assembly platform for the tail. The T6SS tail is structurally, evolutionarily and functionally similar to the contractile tails of bacteriophages. We have shown (...) that TssA docks to the membrane complex, recruits the baseplate complex and initiates and coordinates the polymerization of the inner tube with that of the sheath. Here, we review these recent findings, discuss the variations within TssA-like proteins, speculate on the role of EAEC TssA in T6SS biogenesis and propose future research perspectives. In the environment, bacteria have to cope with other microbial species and therefore have evolved anti-microbial mechanisms. The bacterial Type VI secretion system transports toxins into bacterial and/or eukaryotic cells using a contractile mechanism. At the architectural level, the T6SS could be viewed as a nano-speargun assembled in the bacterial cytoplasm and anchored to a trans-envelope complex. We describe and speculate on recent findings demonstrating that the TssA subunit is involved in the different stages of T6SS biogenesis. (shrink)

The concept of craniofacial difference refers to a set of innate or acquired features causing facial abnormalities. While craniofacial difference is usually understood as an individual fact and is currently overlooked in the definitions of disability that govern disability policies, this study addresses it in its disregarded social dimensions, as shown in a case of the Supreme Court of Canada in 2021. The study then proposes a theological reflection on how the craniofacial anomaly destabilizes certain cultural patterns that guide our (...) visions of the world and how it invites us to engage in a different relationship to reality and meaning.

In early embryonic development, the cell cycle is paced by a biochemical oscillator involving cyclins and cyclin-dependent kinases (cdks). Essentially the same machinery operates in all eukaryotic cells, although after the first few divisions various braking mechanisms (the so-called checkpoints) become significant. Haase and Reed have recently shown that yeast cells have a second, independent oscillator which coordinates some of the events of the G1 phase of the cell cycle.(1) Although the biochemical nature of this oscillator is not known,it seems (...) unlikely to be a redundant cyclin/cdk system.
