This is an introduction to a collection of articles on the conceptual history of epigenesis, from Aristotle to Harvey, Cavendish, Kant and Erasmus Darwin, moving into nineteenth-century biology with Wolff, Blumenbach and His, and onto the twentieth century and current issues, with Waddington and epigenetics. The purpose of the topical collection is to emphasize how epigenesis marks the point of intersection of a theory of biological development and a theory of active matter. We also wish to show that the (...) concept of epigenesis existed prior to biological theorization and that it continues to permeate thinking about development in recent biological debates. (shrink)

La présente étude propose une relecture de trois théoriciens dont les investigations continuent à servir de pierre angulaire à la théâtrologie : celles d'Aristote dont La Poétique, outre le fait qu'elle consacre le théâtre occidental, sert de fondement à l'esthétique dramatique et celles, plus récentes, d'Antonin Artaud et de Bertolt Brecht qui, bien qu'ils aient réfuté radicalement les théories aristoté- liciennes, ne se sont pas moins distingués l'un de l'autre pour donner les deux grandes voies que l'on sait à la (...) réflexion dramaturgique contemporaine. Ces spéculations seront envisagées sous l'éclairage décisif de la mimèsis et de la catharsis qui ne se posent pas chez eux comme des notions distinctes, mais comme l'avers et l'envers d'un même travail sur un réel à chaque fois redéfini, qu'il s'agisse de l'obéissance aristotélicienne à une stricte logique narrative, de l'utopique déculturation artaudienne ou de l'engagement brechtien.The author proposes a review of three major theoreticians whose works are considered to be the corner-stones of theatrical studies : Aristotle, whose Poetics, the first reflexion on Occidental theatre, also serve as the foundation of the aesthetics of drama, and, closer to us, Antonin Artaud and Bertolt Brecht who, although unanimous in rejecting the Aristotelian theory, have quite different views on contemporary theatre. Their definitions are analyzed in the light of mimesis and catharsis, which are not taken here as separate notions, but rather as a mean of grasping the fluctuant outlines of the concept of "reality", be it Aristotle's obedience to a strict narrative structure, Artaud's denial of culture or Brecht's political commitment.

‘The Image of Thought’ could be considered to be the most important piece of writing in the entire Deleuzian corpus. This is the chapter of Difference and Repetition that several decades later, Deleuze claims is the ‘most necessary and the most concrete’ (Deleuze 1994: xvii) section of the book, and the one that provides a basis for his later work with Guattari. Here, Deleuze engages with two basic issues. First, he separates out his conception of thinking, and with it, philosophy, (...) from prior philosophical approaches, explaining why the difference of his philosophy from prior systems itself differs from the traditional relationship between philosophical positions. Second, he raises the question of how one should begin to philosophise. As we will see, philosophy often operates by the recognition of implicit presuppositions in prior thinkers, and their refutation. Descartes, for instance, criticises Aristotle for presupposing the transparency of categories such as rational and animal. Kant, in turn, criticises Descartes for presupposing the determinability of his own foundational moment, the cogito. If we see the development of philosophy as the unmasking and critique of presuppositions of prior systems, then the endpoint of philosophy will be a system entirely without presuppositions. This is the goal Hegel aims at with his system of absolute idealism. Deleuze’s claim is that such a model of the progress of philosophy itself operates within one overarching assumption: the good will of thinking. In this essay, I want to relate these questions of thinking and beginnings to the work of one of Deleuze’s predecessors. Deleuze writes of Ludwig Feuerbach that ‘Feuerbach is among those who have pursued farthest the problem of where to begin.’ (Deleuze 1994: 319) As we shall see, prefiguring Deleuze, Feuerbach accuses Hegel of operating within ‘an image of Reason’. While Feuerbach is famous as a precursor of Marx, and for his critique of traditional accounts of religion, I want to here focus on an early piece by Feuerbach, his Critique of Hegelian Philosophy. Here Feuerbach sets out the limitations of traditional philosophical accounts, and provides the groundwork for his own later materialism. Deleuze discovered Feuerbach through his friend Althusser’s translation of his work, published in 1960. While many of the intuitions behind Deleuze’s critique of the image of thought can be found within a broader pantheon of thinkers, including Nietzsche, Bergson, and Foucault, the specific mechanics of Deleuze’s criticism bear a striking resemblance to the formulation of the critique of philosophy in Feuerbach’s earlier thought. I want to explore this connection, first by looking at the dialectical interrelation of two thinkers, Descartes and Hegel, to get a sense for how criticism in philosophy typically operates. I then want to move on to look at Feuerbach’s critique of Hegel and philosophy more generally, drawing out several aspects that will be taken up by Deleuze himself. I will then look at some of the ways in which Deleuze goes beyond Feuerbach by recognising some of the limitations that persist in Feuerbach’s own analysis. I will conclude by showing how Deleuze’s desire to think the two common acceptations of aesthetics together (the artistic and the sensible) bring Feuerbach into relation with an unexpected figure: the playwright and poet, Antonin Artaud.

In lieu of an abstract, here is a brief excerpt of the content:Basic Theatrical Understanding: Considerations for James HamiltonNoël Carroll (bio)The publication of The Art of Theater by James Hamilton is a seminal event in the philosophy of theater.1 As the first book-length study of theater in the analytic tradition of philosophy, it will be a touchstone for many years of future discussion and debate. Anyone interested in the philosophy of theater will need to address Professor Hamilton’s accomplishment.The leading idea (...) in The Art of Theater is that theatrical performance is an independent art form. That is, theatrical performance, as such, is not, as Aristotle suggested by his demotion of spectacle, a mere adjunct to literature, or essentially a medium for illustrating dramatic and comedic texts. Theatrical performance itself is an art in its own right. This view of theater art has been increasingly apparent in the practices of modern theater in the West, but these practices—as exemplified by Gordon Craig, Vsevolod Meyerhold, Jacques Copeau, Bertolt Brecht, Antonin Artaud, Jerzy Grotowski, and, more recently, Robert Wilson—merely revealed what has always been the case: that theater is at root a performing art.Although for centuries theater in the West had been conceptualized as a text-based art, Hamilton maintains that this tradition is local. Theatrical performances in other cultures need not be the enactment of antecedently written-out texts. Furthermore, even within Western culture, most of us see and discuss plays without ever reading the texts upon which they are based. Hamilton takes these facts to support his view that theatrical performance is an autonomous art form. Among other things, this means that the critical model that presumes that the success of a theatrical performance must be assessed against the effectiveness of its implementation of the pertinent preexisting literary text is a misguided one. Although a preexisting literary text may be an ingredient in the production of a theatrical performance, fidelity to the aforesaid text is not mandated by the art of theater. [End Page 15]Insofar as theatrical performance is an art in its own right, it may—and quite clearly, as in the cases of the Performance Group, Kraken, Mabou Mines, etc., often does—adapt written texts for its own purposes. Moreover, refashioning the text, where there is one, is not simply an avant-garde practice; most productions edit the text for their own purposes. Kenneth Branagh’s Hamlet, which omitted no word from the accepted version of the text, was the exception to the rule. Thus, what Hamilton calls the ingredients model of the relation of texts to theatrical performances has the advantage on its side of better corresponding to actual practices, as compared to the notion that a theatrical performance is to be understood as a matter of bringing a literary text to life.Of course, one apparent advantage that the text-implementation model of theatrical performance might seem to possess is that it appears to have a way ready-to-hand for identifying theatrical performances. Gielgud’s performance, Olivier’s performance, and Burton’s performance are, ex hypothesi, all performances of Hamlet because they are all performances of Shakespeare’s text to which they all roughly comply. If, following Hamilton, we sever the relationship to the play-text, how can we account for the way in which we identify theatrical performances?2 That is, independently of reference to texts, how do we identify a theatrical performance as another instance of Hamlet?In order to solve this problem, Hamilton introduces the idea of “a basic understanding” of a theatrical performance. The basic understanding of a theatrical performance is, on Hamilton’s account, said to involve no more than comprehending on a moment-to-moment basis the ongoing bits of dialogue and stage action as they evolve, as well as understanding the transitions from one scene to another while also responding physically in a suitable manner to the evolving story (for example, laughing where laughter is appropriate) or emoting responsively to what is happening onstage. So, one has a basic understanding of a scene if, when the Musketeer says “On guard,” the spectator takes this to be an invitation to a duel; and when a rival character draws his sword, the...

One of the main objections against effective altruism is the so-called institutional critique, according to which the EA movement neglects interventions that affect large-scale institutions. Alexander Dietz has recently put forward an interesting version of this critique, based on a theoretical problem affecting act-utilitarianism, which he deems as potentially conclusive against effective altruism. In this article I argue that his critique is not as promising as it seems. I then go on to propose another version of the institutional critique. In (...) contrast to Dietz's version, it targets not the core principles of effective altruism but rather some important methodological assumptions made in EA research, namely diminishing marginal returns and low-hanging fruits. One key conclusion is that it may be time for critics of effective altruism to shift their attention from the theoretical core principles of effective altruism towards the methodological tools actually employed in practice by the EA movement.

Revelation, or the view that the essence of phenomenal properties is presented to us, is as intuitively attractive as it is controversial. It is notably at the core of defences of anti-physicalism. I propose in this paper a new argument against Revelation. It is usually accepted that low-level sensory phenomenal properties, like phenomenal red, loudness or brightness, stand in relation of similarity and quantity. Furthermore, these similarity and quantitative relations are taken to be internal, that is, to be fixed by (...) what their relata are. I argue that, under some plausible additional premises, no account of what grounds these relations in the essence of their relata is consistent with Revelation, at least if we take common phenomenological descriptions for granted. As a result, the plausibility of Revelation is undermined. One might however resist this conclusion by weakening the epistemic relation postulated between subjects and their phenomenal properties.

Algorithmic decision making is used in an increasing number of fields. Letting automated processes take decisions raises the question of their accountability. In the field of computational journalism, the algorithmic accountability framework proposed by Diakopoulos formalizes this challenge by considering algorithms as objects of human creation, with the goal of revealing the intent embedded into their implementation. A consequence of this definition is that ensuring accountability essentially boils down to a transparency question: given the appropriate reverse-engineering tools, it should be (...) feasible to extract design criteria and to identify intentional biases. General limitations of this transparency ideal have been discussed by Ananny and Crawford :973–989, 2018). We further focus on its technical limitations. We show that even if reverse-engineering concludes that the criteria embedded into an algorithm correspond to its publicized intent, it may be that adversarial behaviors make the algorithm deviate from its expected operation. We illustrate this issue with an automated news recommendation system, and show how the classification algorithms used in such systems can be fooled with hard-to-notice modifications of the articles to classify. We therefore suggest that robustness against adversarial behaviors should be taken into account in the definition of algorithmic accountability, to better capture the risks inherent to algorithmic decision making. We finally discuss the various challenges that this new technical limitation raises for journalism practice. (shrink)

Le messianisme a souvent été, dans l’histoire du judaïsme, le nom de moments de crise et de renversement de la tradition. Au sein de la modernité juive, il revient particulièrement à Levinas et à Benjamin de retravailler la notion de messianisme pour tenter d’en actualiser la portée éthique et politique dans une optique offensive vis-à-vis du politique. On se propose ici d’approfondir le dialogue entre ces deux auteurs sur la question du messianisme éthique afin d’y trouver un possible renouvellement de (...) la pensée révolutionnaire, mais aussi pour questionner la violence propre de la révolution et pour signaler les premiers jalons d’une pensée de la communauté éthique et messianique.

Semantic deference allows for the meaning of a word w a speaker uses to be determined by the way other speakers would understand or use w. That semantic deference has some role to play in semantic content attributions is intuitive enough. Nevertheless, the exact conditions under which semantic deference takes place are still open for discussion. A key issue that the article critically examines is Recanati’s requirement that deferential uses be grounded, that is, that deferential uses be linked to non-deferential (...) uses (Recanati 1997; 2000). After distinguishing between semantic and epistemic deference, I submit that the only way to maintain the Groundedness Thesis for truly semantic deference is to allow deference to idealized future linguistic collectives. I conclude that this is too high a price to pay for Groundedness and I suggest that it should be rejected as a semantic thesis. (shrink)

The heterogeneity problem, which stems from the alleged difficulty of finding out what all pleasant experiences have in common, is largely considered as a substantial issue in the philosophy of pleasure, one that is usually taken as the starting point for theorizing about the essence of pleasure. The goal of this paper is to move the focus away from the heterogeneity problem and toward an alternative approach to pleasure. To do this, I first show that, although the approach stemming from (...) the heterogeneity problem has led to an interesting discussion about the essence of pleasure, it has usually endorsed an introspectionist methodology and other problematic assumptions that have led to doubtful results. I thus propose a natural-kind approach to pleasure, which seeks to determine what, if any, the natural kind of pleasure would consist in. This approach broadens the investigation of pleasure by enabling the use of a larger range of methodological tools, thus opening new promising directions for research. (shrink)

We show that there is a low T-upper bound for the class of K-trivial sets, namely those which are weak from the point of view of algorithmic randomness. This result is a special case of a more general characterization of ideals in $\Delta _2^0 $ T-degrees for which there is a low T-upper bound.

The paper is about the conception of free will. It describes arguments and counterarguments for free will. Its main aim is to submit a novel argumentation opposite to traditional arguments regarding, for instance, accounting of free will, emergent free will in complex brain or anthropocentric argument with emergent free will in human reason.

The paper describes the context and the origin of a particular debate that concerns the evolution of phenotypic plasticity. In 1965, British biologist A. D. Bradshaw proposed a widely cited model intended to explain the evolution of norms of reaction, based on his studies of plant populations. Bradshaw’s model went beyond the notion of the “adaptive norm of reaction” discussed before him by Dobzhansky and Schmalhausen by suggesting that “plasticity” the ability of a phenotype to be modified by the environment (...) should be genetically determined. To prove Bradshaw’s hypothesis, it became necessary for some authors to identify the pressures exerted by natural selection on phenotypic plasticity in particular traits, and thus to model its evolution. In this paper, I contrast two different views, based on quantitative genetic models, proposed in the mid-1980s: Russell Lande and Sara Via’s conception of phenotypic plasticity, which assumes that the evolution of plasticity is linked to the evolution of the plastic trait itself, and Samuel Scheiner and Richard Lyman’s view, which assumes that the evolution of plasticity is independent from the evolution of the trait. I show how the origin of this specific debate, and different assumptions about the evolution of phenotypic plasticity, depended on Bradshaw’s definition of plasticity and the context of quantitative genetics.

In recent years the study of well-being has attracted considerable attention, fostering hope that the scientific community will ultimately succeed in discovering its very nature, thereby emulating successful scientific projects in other disciplines. However, there have been recurring worries about how to measure and define well-being. In this context, Hersch (Br J Philos Sci 73:1045–1065, 2022) has recently argued that we could progressively alleviate these worries through an iterative dialogue between theory and measurement, by seeing them as stemming from a (...) coordination problem. In this article, I argue that the concept of well-being fails to meet the prerequisites for Hersch’s approach. If the latter is the best defense of the capacity of science to uncover the nature of well-being, it follows that the science of well-being should probably relinquish this ambition. (shrink)

Antonin Artaud was a poet, theorist, philosopher, essayist, playwright, actor and director, and one of the 20th century’s most important theoreticians of drama. His theory of the ‘Theatre of Cruelty’ has influenced playwrights as diverse as Beckett, Genet, Albee and Gelber. Magic was always a central concept for Artaud, and in nearly all his writing it is given the most positive force, as something capable of healing the rift between words and things, culture and life. But during his nine years (...) of incarceration in mental asylums, magic seemed to lose its illuminating transformative power and to become demonic and persecutory. Artaud entered the realm of spectres and vampires which he believed were sucking the vitality from his mind and body. Artaud later filled twelve little exercise books with an account of his struggles to escape this physical, psychological and artistic hell. The first eleven books are filled with fragments of writing and extraordinary sketches of totemic figures, pierced bodies and enigmatic machines. Two months before his death, he took a twelfth exercise book and wrote a remarkable, incantatory text, 50 Drawings to Murder Magic. It was the last thing he wrote. (shrink)

L'hédonisme axiologique a une longue histoire en philosophie. Pourtant, il garde une mauvaise réputation qui lui vaut d’être parfois écarté sans ménagement de la discussion philosophique. Cet article se propose de défendre l'hédonisme axiologique en exposant les principaux arguments en sa faveur et en répondant aux principales critiques et confusions dont il fait l'objet. Une attention particulière sera portée aux arguments établissant la spécificité du plaisir et du déplaisir par rapport à toutes les autres choses — amitié, savoir, justice, etc. (...) — dont on pourrait argumenter la valeur finale.While axiological hedonism has a long history in philosophy, it also has a bad reputation, which has led to it being discarded without proper examination of its plausibility. In this article, I defend axiological hedonism by presenting the main arguments in its favour as well as the criticisms and confusions to which it has been subjected. I pay special attention to the arguments that hint at the specificity of pleasure and displeasure in comparison with other things — friendship, knowledge, justice, etc. — that might be argued to have final value.

Kuera, A., On relative randomness, Annals of Pure and Applied Logic 63 61–67. It is the aim of the paper to answer a question raised by M. van Lambalgen and D. Zambella whether there can be a nonrecursive set A having the property that there is a set B such that B is 1-random relative to A and simultaneously A is recursive in B. We give apositive answer to this question as well as further information about relative randomness.

In 1956, in his Principles of Embryology, Conrad Hal Waddington explained that the word “epigenetics” should be used to translate and update Wilhelm Roux’ German notion of “Entwicklungsmechanik” to qualify the studies focusing on the mechanisms of development. When Waddington mentioned it in 1956, the notion of epigenetics was not yet popular, as it would become from the 1980s. However, Waddington referred first to the notion in the late 1930s. While his late allusion clearly reveals that Waddington readily associated the (...) notion of epigenetics with the developmental process, in the contemporary uses of the notion this developmental connotation seems to have disappeared. The advent and success of molecular biology have probably contributed to focusing biologists’ attention on the “genetic” or the “non-genetic” over the “developmental”. In the present paper, I first examine the links that exist, in Waddington’s work, between the classical notion of epigenesis in embryology and those of epigenetics that Waddington proposed to connect, and even synthesize, data both from embryology and genetics. Second, I show that Waddington’s own view of epigenetics has changed over time and I analyze how these changes appear through his many representations of the relationships between genetic signals and developmental processes.

Osvald Demuth studied constructive analysis from the viewpoint of the Russian school of constructive mathematics. In the course of his work he introduced various notions of effective null set which, when phrased in classical language, yield a number of major algorithmic randomness notions. In addition, he proved several results connecting constructive analysis and randomness that were rediscovered only much later.In this paper, we trace the path that took Demuth from his constructivist roots to his deep and innovative work on the (...) interactions between constructive analysis, algorithmic randomness, and computability theory. We will focus specifically on Demuth’s work on the differentiability of Markov computable functions and his study of constructive versions of the Denjoy alternative, Demuth’s independent discovery of the main notions of algorithmic randomness, as well as the development of Demuth randomness, and the interactions of truth-table reducibility, algorithmic randomness, and semigenericity in Demuth’s work.

Joe Sachs has followed up his brilliant translation of Aristotle's Physics with a new translation of Metaphysics. Sachs's translations bring distinguished new light onto Aristotle's works, which are foundational to history of science. Sachs translates Aristotle with an authenticity that was lost when Aristotle was translated into Latin and abstract Latin words came to stand for concepts Aristotle expressed with phrases in everyday Greek language. When the works began being translated into English, those abstract Latin (...) words or their cognates were used, thus suggesting a level of jargon and abstraction, and in some cases misleading interpretation, which was not Aristotle's language or style. These important new translations open up Aristotle's original thought to readers. (shrink)

How do we understand the world around us? How do we solve problems? Often the answer to these questions follows a certain pattern, an algorithm if you wish. This is the case when our analytical left-brain side is at work.

Tout au long de son histoire, la philosophie s’est sentie menacée par le moment sensuel de l’art, le plaisir pris qui risquait de mettre la raison hors d’elle-même. Là où Platon s’en défendit par l’exclusion de la poésie hors de l’enceinte de la cité philosophique, Kant tenta de le domestiquer en l’intégrant au dedans des murs du système. Il espérait ainsi, en assignant une place déterminée au plaisir et au désir, en maîtriser les débordements. Mais le pouvoir de séduction de (...) l’art, comme celui des femmes auquel Kant le renvoie, ne se laisseront pas si aisément contenir dans l’économie systémique et viendront déranger le subtil équilibre architectonique de l’édifice critique.

Books V and VI of Aristotle's Politics constitute a manual on practical politics. In the fifth book Aristotle examines the causes of faction and constitutional change and suggests remedies for political instability. In the sixth book he offers practical advice to the statesman who wishes to establish, preserve, or reform a democracy or an oligarchy. He discusses many political issues, theoretical and practical, which are still widely debated today--revolution and reform, democracy and tyranny, freedom and equality. David Keyt (...) presents a clear and accurate new translation of these books, together with a commentary which, though primarily philosophical, also supplies a key to Aristotle's many historical references. It is intended to guide readers towards a proper understanding of this classic text in the history of political thought, and does not assumes knowledge of Greek or of ancient history and politics.

Quand nous lisons un livre passionnant, quand nous passons une bonne soirée avec des amis ou quand nous dégustons des mets raffinés, nous nous trouvons parfois dans un état de plaisir. La notion de plaisir traverse de nombreux champs de recherche en philosophie. Une question centrale reste sans doute celle de sa nature : qu’est-ce donc que le plaisir ? Pour y répondre, une comparaison avec d'autres entités mentales plus familières se révèle fructueuse, et permet de mettre à jour ses (...) spécificités propres. La définition du plaisir doit rendre compte de sa diversité, puisque le plaisir semble toujours se présenter sous des formes multiples : qu'y a-t-il de commun parmi toutes les instances de plaisir ? Par ailleurs, le plaisir semble souvent avoir un objet, ce qui soulève une série de questions : Quel type de chose peut être un objet du plaisir ? Dans quelle mesure l'objet du plaisir constitue-t-il le plaisir lui-même ? Plus généralement, quelle est la nature du lien entre le plaisir et son objet ? Ces questions seront abordées dans la Section 1. Au-delà de ces questions définitionnelles, des questions plus spécifiques se posent concernant la manière dont on peut rendre compte du plaisir dans une optique naturaliste : dans quelle mesure le plaisir est-il une entité qui s’intègre dans une image unifiée du monde dans lequel on vit ? Puisqu'il est généralement entendu que la science manifeste cette ambition unificatrice, comment peut-on rendre compte du plaisir de manière scientifique ? La Section 2 est dédiée à ces questions. Une des principales difficultés rencontrées est que le plaisir ne semble pas neutre. Il paraît plutôt avoir une valeur affective positive, dans un sens qui reste bien sûr à éclaircir. Cette valeur se manifeste d'abord dans le fait que le plaisir est susceptible d'orienter nos actions et réactions : nous sommes typiquement attirés par le plaisir, de la même manière que nous cherchons à éviter la souffrance. C'est l'aspect motivationnel du plaisir. La valeur affective du plaisir semble cependant aller au-delà de son rôle motivationnel, pour donner lieu à des caractéristiques normatives. Non seulement le plaisir motive certaines actions, mais il les justifierait aussi, en fournissant des raisons d'agir qui semblent valides. Plus encore, le plaisir semble bon pour nous, ou nous faire du bien. Il semble donc avoir une valeur prudentielle, en ce qu'il contribuerait à rendre notre vie meilleure. Cela pourrait alors justifier son intégration dans le domaine de la morale. Ces considérations seront l’objet de la Section 3. (shrink)
