The development of synthetic biology calls for accurate understanding of the critical functions that allow construction and operation of a living cell. Besides coding for ubiquitous structures, minimal genomes encode a wealth of functions that dissipate energy in an unanticipated way. Analysis of these functions shows that they are meant to manage information under conditions when discrimination of substrates in a noisy background is preferred over a simple recognition process. We show here that many of these functions, including transporters and (...) the ribosome construction machinery, behave as would behave a material implementation of the informationmanaging agent theorized by Maxwell almost 150 years ago and commonly known as Maxwell’s demon (MxD). A core gene set encoding these functions belongs to the minimal genome required to allow the construction of an autonomous cell. These MxDs allow the cell to perform computations in an energy-efficient way that is vastly better than our contemporary computers. (shrink)

Dans un monde dominé par les conflits, il arrive qu’il faille se défendre. L’invention des armes a évolué en parallèle avec le savoir technique, puis scientifique, et il est même arrivé que la recherche d’applications militaires ait joué un rôle moteur dans la découverte scientifique. Lorsque les armes ne servent pas à attaquer d’autres nations, leur fabrication et leur commerce se justifient morale- ment. Il faut cependant qu’elles ne puissent échapper à ceux qui les construisent et doivent en contrôler la (...) diffusion. Facilement mise en œuvre, la guerre utilisant des organismes vivants ou ce qu’ils pro- duisent comme armes est très ancienne. Or l’originalité des êtres vivants est qu’ils se multiplient, qu’un seul individu suffit à recouvrir la Terre de ses descendants. La biologie ne se prête jamais à un usage militaire moralement défendable parce que le confinement au champ de bataille est impossible. De ce fait, les applications de la biologie ont été vite écartées du domaine de la Défense permise par les traités internationaux. La Convention de 1972 sur l’Interdiction des Armes Biologiques et à Toxines (CIABT), entrée en vigueur en 1975, est aujourd’hui signée par 183 pays (ratifiée par 175) sur un total de 193, sans compter Taïwan qui l’a ratifiée mais n’est pas reconnu par l’ONU. Elle interdit la mise au point, la fabrication, l’acquisition, le transfert, la conservation, le stockage et l’utilisation des armes bio- logiques et à toxines. Elle constitue un élément essentiel de la lutte contre la prolifération des armes de destruction massive. (shrink)

Synthetic biology (SynBio) covers two main areas: application engineering, exemplified by metabolic engi- neering, and the design of life from artificial building blocks. As the general public is often reluctant to embrace synthetic approaches, preferring nature to artifice, its immediate future will depend very much on the public’s reaction to the unmet needs created by the pervasive demands of sustainability. On the other hand, this reluctance should not have a negative impact on research that will now take into account the (...) existence of the multiple transitions that cells face over time. The ages of life—birth, development, maturation, senescence and death—reflect specific key transitions and have, until now, rarely been taken into account in SynBio designs. This results in a mismatch between novelty and the very long evolutionary time that led to the existing chassis [remember that this is the common term used to describe the cellular framework as seen by synthetic biologists (de Lorenzo & Danchin, 2008)]. It also implies that, in general, transitions between growth stages will be taken into account with the appro- priate embodiment of highly specific processes. This is particularly important when adapting new models to their host, whether natural or artificial. Adaptation fol- lows two stages, short-term accommodation of new entities and long-term assimilation into the cell as a whole. This requires discrimination between classes of entities. We suggest that proteins playing the essential role of Maxwell’ demons, here named Maxwell’s dis- criminators (MxDs) to refer to their original function, will permit the assimilation and accommodation of artificial constructs. As a consequence, we can foresee that class discrimination, beyond mere recognition, will be implemented in SynBio 2.0, leading to an authentic par- adigm shift (Kuhn, 1996), based on conceptions that embody information as a genuine currency of reality. (shrink)

Assembly of minimal genomes revealed many genes encoding unknown functions. Three overlooked functional categories account for some of them. Cells are prone to make errors and age. As a first key function, discrimination between proper and changed entities is indispensable. Discrimination requires management of information, an authentic, yet abstract, cur- rency of reality. For example proteins age, sometimes very fast. The cell must identify, then get rid of old proteins without destroying young ones. Implementing discrimination in cells leads to the (...) second set of functions, usually ignored. Being abstract, information must nevertheless be embodied into material entities, with unavoidable idiosyncratic properties. This brings about novel unmet needs. Hence, the buildup of cells elicits specific but awkward material implementations, ‘kludges’ that become essential under particular settings, while difficult to identify. Finally, a third functional category char- acterizes the need for growth, with metabolic implementations allowing the cell to put together the growth of its cytoplasm, membranes, and genome, spanning different spatial dimensions. Solving this metabolic quandary, critical for engineering novel synthetic biology chassis, uncovered an unexpected role for CTP synthetase as the coordinator of nonhomothetic growth. Because a significant number of SynBio constructs aim at creating cell factories we expect that they will be attacked by viruses (it is not by chance that the function of the CRISPR system was identified in industrial settings). Substantiating the role of CTP, natural selection has dealt with this hurdle via synthesis of the antimetabolite 30-deoxy-30,40-didehydro- CTP, recruited for antiviral immunity in all domains of life.

The linguistic foundations of science and technology include many terms that have been borrowed from ancient languages. In the case of terms with origins in the Greek language, the modern meaning can often differ significantly from the original one. Here we use the PubMed database to demonstrate the prevalence of words of Greek origin in the language of modern science, and call for scientists to exercise care when coining new terms.

Science is founded on a method based on critical thinking. A prerequisite for this is not only a sufficient command of language but also the comprehension of the basic concepts underlying our understanding of reality. This constraint implies an awareness of the fact that the truth of the World is not directly accessible to us, but can only be glimpsed through the construction of mod- els designed to anticipate its behaviour. Because the relationship between models and reality rests on the (...) interpretation of founding postulates and in- stantiations of their predictions (and is therefore deeply rooted in language and culture), there can be no demarcation between science and non-science. However, critical thinking is essential to ensure that the link between models and reality is gradually made more adequate to reality, based on what has already been established, thus guaranteeing that science progresses on this basis and excluding any form of relativism.

Science and engineering rely on the accumulation and dissemination of knowledge to make discoveries and create new designs. Discovery-driven genome research rests on knowledge passed on via gene annotations. In response to the deluge of sequencing big data, standard annotation practice employs automated procedures that rely on majority rules. We argue this hinders progress through the generation and propagation of errors, leading investigators into blind alleys. More subtly, this inductive process discourages the discovery of novelty, which remains essential in biological (...) research and reflects the nature of biology itself. Annotation systems, rather than being repositories of facts, should be tools that support multiple modes of inference. By combining deduction, induction and abduction, investigators can generate hypotheses when accurate knowledge is extracted from model databases. A key stance is to depart from ‘the sequence tells the structure tells the function’ fallacy, placing function first. We illustrate our approach with examples of critical or unexpected pathways, using MicroScope to demonstrate how tools can be implemented following the principles we advocate. We end with a challenge to the reader. (shrink)

Anticiper les épidémies est le souhait le plus vif de toutes les institutions qui veillent sur la santé publique. Un raisonnement naïf permet de penser qu’il suffit de faire évoluer en laboratoire un organisme potentiellement pathogène pour savoir comment sa descendance pourra devenir plus virulente pour l’homme. Il est alors facile de faire croître cet organisme sur des cellules humaines, qu’il infecte mal pour commencer, puis de retenir ses descendants au fur et à mesure qu’ils deviennent plus infectieux. La vision (...) optimiste affirme alors que les caractériser permettra de construire des défenses appropriées. Bien des variations sur ce thème sont possibles, y compris avec l’aide de la synthèse artificielle de variants dont on saurait imaginer la pathogénicité pour l’homme. Depuis plus de deux décennies, des chercheurs développent des expériences de ce type, dite de « gain de fonction » (GdF). Leur interprétation repose sur l’illusion que nous savons prévoir l’évolution des êtres vivants. En réalité, ceux que nous observons aujourd’hui ont été sélectionnés au cours du temps précisément parce qu’ils conduisent toujours à des comportements imprévisibles. Une règle clé de l’évolution est que la vie, pour durer dans des circonstances qui ne peuvent être prévues, doit sans cesse faire émerger des formes innovantes. À ce caractère propre à la vie s’ajoute un imprévisible lié à l’impéritie humaine, cause de l’omniprésence des accidents de laboratoire. Or, en virologie spécialement, l’accident est la règle et non l’exception. Il faut ajouter que le caractère public de ces expériences les rend utilisables par toutes les structures malveillantes qui sont hélas répandues dans le monde. Il n’est pas difficile alors d’imaginer les conséquences catastrophiques des expériences de GdF. Nous proposons donc qu’elles soient purement et simplement interdites et que toute transgression soit sévèrement punie, en frappant d’abord au porte-monnaie, ce qui semble être la meilleure façon de faire dans nos sociétés devenues universellement vénales.

Synthetic biology aims at reconstructing life to put to the test the limits of our understanding. It is based on premises similar to those which permitted invention of computers, where a machine, which reproduces over time, runs a program, which replicates. The underlying heuristics explored here is that an authentic category of reality, information, must be coupled with the standard categories, matter, energy, space and time to account for what life is. The use of this still elusive category permits us (...) to interact with reality via construction of self-consistent models producing predictions which can be instantiated into experiments. While the present theory of information has much to say about the program, with the creative properties of recursivity at its heart, we almost entirely lack a theory of the information supporting the machine. We suggest that the program of life codes for processes meant to trap information which comes from the context provided by the environment of the machine. (shrink)

Two decades ago, Rolf Landauer (1991) argued that “information is physical” and ought to have a role in the scientific analysis of reality comparable to that of matter, energy, space and time. This would also help to bridge the gap between biology and mathematics and physics. Although it can be argued that we are living in the ‘golden age’ of biology, both because of the great challenges posed by medicine and the environment and the significant advances that have been made—especially (...) in genetics and molecular and cell biology—we feel that information as an essential aspect of life has been neglected, or at least misunderstood. We therefore summon Maxwell’s Demon and its distant relative the ratchet, and apply these to biology. (shrink)

The notion of antifragility, an attribute of systems that makes them thrive under variable conditions, has recently been proposed by Nassim Taleb in a business context. This idea requires the ability of such systems to ‘tinker’, i.e., to creatively respond to changes in their environment. A fairly obvious example of this is natural selection-driven evolution. In this ubiquitous process, an original entity, challenged by an ever-changing environment, creates variants that evolve into novel entities. Analyzing functions that are essential during stationary-state (...) life yield examples of entities that may be antifragile. One such example is proteins with flexible regions that can undergo functional alteration of their side residues or backbone and thus implement the tinkering that leads to antifragility. This in-built property of the cell chassis must be taken into account when considering construction of cell factories driven by engineering principles. (shrink)

The abstract basis of modern computation is the formal description of a finite state machine, the Universal Turing Machine, based on manipulation of integers and logic symbols. In this contribution to the discourse on the computer-brain analogy, we discuss the extent to which analog computing, as performed by the mammalian brain, is like and unlike the digital computing of Universal Turing Machines. We begin with ordinary reality being a permanent dialog between continuous and discontinuous worlds. So it is with computing, (...) which can be analog or digital, and is often mixed. The theory behind computers is essentially digital, but efficient simulations of phenomena can be performed by analog devices; indeed, any physical calculation requires implementation in the physical world and is therefore analog to some extent, despite being based on abstract logic and arithmetic. The mammalian brain, comprised of neuronal networks, functions as an analog device and has given rise to artificial neural networks that are implemented as digital algorithms but function as analog models would. Analog constructs compute with the implementation of a variety of feedback and feedforward loops. In contrast, digital algorithms allow the implementation of recursive processes that enable them to generate unparalleled emergent properties. We briefly illustrate how the cortical organization of neurons can integrate signals and make predictions analogically. While we conclude that brains are not digital computers, we speculate on the recent implementation of human writing in the brain as a possible digital path that slowly evolves the brain into a genuine (slow) Turing machine.

Pasteur’s originality in the way he developed pure research is to have understood the importance, for society, of the underlying motivation. Curiosity, of course, is a strong motivation, which explains why we seek to understand the origin of life. But, in front of the immensity of the possible choices, why not, also, choose to start from questions of economic interest (diseases of beer and wine, diseases aVecting the silk industry . . . ) Finally, of course, health is a constant (...) preoccupation, but the diseases, which have no borders, often come from tropical countries and Asia especially. It is therefore necessary to settle there, but not to come and impose one’s point of view, but on the contrary to use the knowledge coming from the local culture in order to open new ways of understanding the reality of the world.

To construct a synthetic cell we need to understand the rules that permit life. A central idea in modern biology is that in addition to the four entities making reality, matter, energy, space and time, a fifth one, information, plays a central role. As a consequence of this central importance of the management of information, the bacterial cell is organised as a Turing machine, where the machine, with its compartments defining an inside and an outside and its metabolism, reads and (...) expresses the genetic program carried by the genome. This highly abstract organisation is implemented using concrete objects and dynamics, and this is at the cost of repeated incompatibilities (frustration), which need to be sorted out by appropriate «patches». After describing the organisation of the genome into the paleome (sustaining and propagating life) and the cenome (permitting life in context), we describe some chemical hurdles that the cell as to cope with, ending with the specific case of the methionine salvage pathway. (shrink)

Life can be defined as combining two entities that rest on completely different physico-chemical properties and on a particular way of handling information. The cell, first, is a « machine », that combines elements which are quite similar (although in a fairly fuzzy way) to those involved in a man-made factory. The machine combines two processes. First, it requires explicit compartmentalisation, including scaffolding structures similar to that of the châssis of engineered machines. In addition, cells define clearly an inside, the (...) cytoplasm, and an outside. The cell envelope is more or less complicated in bacteria, and it is much more complicated in organisms made of cells with a nucleus (eukaryotes). Second, the machine also requires dynamic chemical processes, collectively named metabolism, that can be split into intermediary metabolism, managing chemical transformations and transport of small building blocks and management of energy (often with a rotating nanomachine, ATP synthase), and the macromolecule synthesis, salvage and turnover machinery which uses a variety of nanomachines, the ribosome being the most prominent one. The second entity which needs to be associated to life is the genetic program, in the form of the genome, composed of one or several chromosomes made of DNA. This is the entity which associates most clearly to information. -/- Natural selection uses information in a particular way: it is a process that uses energy to prevent degradation of any functional entity. This process keeps building up novel information within organisms. (shrink)

The dichotomy between the research to generate knowledge and the application of that knowledge to benefit mankind seems to be a recent development. In fact, more than 100 years ago Louis Pasteur avoided this debate altogether: one of his major, yet forgotten, contributions to science was the insight that research and its applications are not opposed, but orthogonal to each other (Stokes, 1997). If Niels Bohr ‘invented’ basic academic research—which was nevertheless the basis for many technological inventions and industrial applications—Pasteur (...) developed what we might call ‘motivated’ research. -/- How is research motivated and by what? By definition, scientists are citizens and members of the general public and, like the public, they are motivated by two forces: on the one hand, in Rudyard Kipling's words, “man's insatiable curiosity”; on the other hand, a desire for maintaining and improving their well‐being. These are not contradictory to one another; curiosity nourishes dreams of a brighter future and leads to discoveries that contribute to well‐being. (shrink)

A formalism is introduced to represent the connective organization of an evolving neuronal network and the effects of environment on this organization by stabilization or degeneration of labile synapses associated with functioning. Learning, or the acquisition of an associative property, is related to a characteristic variability of the connective organization: the interaction of the environment with the genetic program is printed as a particular pattern of such organization through neuronal functioning. An application of the theory to the development of the (...) neuromuscular junction is proposed and the basic selective aspect of learning emphasized. (shrink)

The interplay between the virus, infected cells and immune responses to SARS-CoV-2 is still under debate. By extending the basic model of viral dynamics, we propose here a formal approach to describe neutralisation versus weak (or non-)neutralisation scenarios and compare them with the possible effects of antibody-dependent enhancement (ADE). The theoretical model is consistent with the data available in the literature; we show that both weakly neutralising antibodies and ADE can result in final viral clearance or disease progression, but that (...) the immunodynamics are different in each case. As a significant proportion of the world’s population is already naturally immune or vaccinated, we also discuss the implications for secondary infections after vaccination or in the presence of immune system dysfunctions.

Intermediary metabolism molecules are orchestrated into logical pathways stemming from history (L-amino acids, D-sugars) and dynamic constraints (hydrolysis of pyrophosphate or amide groups is the driving force of anabolism). Beside essential metabolites, numerous variants derive from programmed or accidental changes. Broken down, variants enter standard pathways, producing further variants. Macromolecule modification alters enzyme reactions specificity. Metabolism conform thermodynamic laws, precluding strict accuracy. Hence, for each regular pathway, a wealth of variants inputs and produces metabolites that are similar to but not (...) the exact replicas of core metabolites. As corollary, a shadow, paralogous metabolism, is associated to standard metabolism. We focus on a logic of paralogous metabolism based on diversion of the core metabolic mimics into pathways where they are modified to minimize their input in the core pathways where they create havoc. We propose that a significant proportion of paralogues of well-characterized enzymes have evolved as the natural way to cope with paralogous metabolites. A second type of denouement uses a process where protecting/deprotecting unwanted metabolites - conceptually similar to the procedure used in the laboratory of an organic chemist - is used to enter a completely new catabolic pathway.

There is a tendency to take mounted dinosaur skeletons at face value, as the raw data on which the science of paleontology is founded. But the truth is that mounted dinosaur skeletons are substantially intention-dependent—they are artifacts. More importantly, I argue, they are also substantially imagination-dependent: their production is substantially causally reliant on preparators’ creative imaginations, and their proper reception is predicated on audiences’ recreative imaginations. My main goal here is to show that dinosaur skeletal mounts are plausible candidates for (...) art-status. But, what is more, I think they are artworks—specifically, sculptures. (shrink)

For Van Rensselaer Potter (1911–2001), Global Bio-Ethics is about building on the legacy of Aldo Leopold (1887–1948), one of the most notable forest managers of the twentieth century who brought to light the importance of pragmatism in the sciences and showed us a new way to proceed with environmental ethics. Following Richard Huxtable and Jonathan Ives's methodological 'Framework for Empirical Bioethics Research Projects' called 'Mapping, framing, shaping,' published in BMC Medicine Ethics (2019)), we propose operationalizing a framework for Global Bio-Ethics (...) by hybridizing approaches in empirical bioethics and ecosystem management. We explain this framework using the metaphor of forest management. This mixed approach is articulated through three phases: (1) mapping the “landscape” to build a working theory, (2) framing the “scene” to prepare the fieldwork, and (3) shaping bioethics “tools” to stimulate cooperation. Applying this methodology, an adaptive management cycle is outlined to help ensure that political processes are sustainable and socially acceptable, still based on strategic and ethical thinking, but also capable of reshaping failing policies.

The lasting effects of the debate over canon-formation during the 1980s affected the whole field of Humanities, which became increasingly engaged in interrogating the origin and function of the Western canon.

Surveillance programs supporting the management of One Health issues such as antibiotic resistance are complex systems in themselves. Designing ethical surveillance systems is thus a complex task (retroactive and iterative), yet one that is also complicated to implement and evaluate (e.g., sharing, collaboration, and governance). The governance of health surveillance requires attention to ethical concerns about data and knowledge (e.g., performance, trust, accountability, and transparency) and empowerment ethics, also referred to as a form of responsible self-governance. Ethics in reflexive governance (...) operates as a systematic critical-thinking procedure that aims to define its value: What are the “right” criteria to justify how to govern “good” actions for a “better” future? The objective is to lay the foundations for a methodological framework in empirical bioethics, the rudiments of which have been applied to a case study to building reflexive governance in One Health. This ongoing critical thinking process involves “mapping, framing, and shaping” the dynamics of interests and perspectives that could jeopardize a “better” future. This paper proposes to hybridize methods to combine insights from collective deliberation and expert evaluation through a reflexive governance functioning as a community-based action-ethics methodology. The intention is to empower individuals and associations in a dialogue with society, which operation is carried out using a case study approach on data sharing systems. We based our reasoning on a feasibility study conducted in Québec, Canada (2018–2021), envisioning an antibiotic use surveillance program in animal health for 2023. Using the adaptive cycle and governance techniques and perspectives, we synthesize an alternative governance model rooted in the value of empowerment. The framework, depicted as a new “research and design (R&D)” practice, is linking operation and innovation by bridging the gap between Reflexive, Evaluative, and Deliberative reasonings and by intellectualizing the management of democratizing critical thinking locally (collective ethics) by recognizing its context (social ethics). Drawing on the literature in One Health and sustainable development studies, this article describes how a communitarian and pragmatic approach can broaden the vision of feasibility studies to ease collaboration through public-private-academic partnerships. The result is a process that “reassembles” the One Health paradigm under the perspective of global bioethics to create bridges between the person and the ecosystem through pragmatic ethics. (shrink)

This paper explores what happens when artists fail to execute their goals. I argue that taxonomies of failure in general, and of failed-art in particular, should focus on the attempts which generate the failed-entity, and that to do this they must be sensitive to an attempt’s orientation. This account of failed-attempts delivers three important new insights into artistic practice: there can be no accidental art, only deliberate and incidental art; art’s intention-dependence entails the possibility of performative failure, but not of (...) failed-art; and art’s intention-dependence is perfectly compatible with the role that luck plays in artistic creation.

It is widely agreed that fiction is necessarily incomplete, but some recent work postulates the existence of universal fictions—stories according to which everything is true. Building such a story is supposedly straightforward: authors can either assert that everything is true in their story, define a complement function that does the assertoric work for them, or, most compellingly, write a story combining a contradiction with the principle of explosion. The case for universal fictions thus turns on the intuitive priority we assign (...) to the law of non-contradiction. My goal in this paper is to show that our critical and reflective literary practices set constraints on story-telling which preclude universal fictions. I will raise four stumbling blocks for universal fictionalists: the gap between saying and making true, our actual interpretive reactions to story-level contradictions, the criteria we accept for what counts as a story in our literary practices, and the undesirability of the universal fictionalist’s closure principles.

The premise that every work belongs to an art-kind has recently inspired a kind-centred approach to theories of art. Kind-centred analyses posit that we should abandon the project of giving a general theory of art and focus instead on giving theories of the arts. The main difficulty, however, is to explain what makes a given kind an art-kind in the first place. Kind-centred theorists have passed this buck on to appreciative practices, but this move proves unsatisfactory. I argue that the (...) root of this dissatisfaction stems not from the act of kicking the can down the road, but from not kicking it far enough. The missing ingredient, I argue, is a notion of convention which does the work of marking the difference between art and non-art for a given physical medium. (shrink)

It is widely believed, among philosophers of literature, that imagining contradictions is as easy as telling or reading a story with contradictory content. Italo Calvino’s The Nonexistent Knight, for instance, concerns a knight who performs many brave deeds, but who does not exist. Anything at all, they argue, can be true in a story, including contradictions and other impossibilia. While most will readily concede that we cannot objectually imagine contradictions, they nevertheless insist that we can propositionally imagine them, and regularly (...) do, simply by entertaining a text which prompts us to do so. I argue that this narrative does not bear scrutiny for two main reasons. First, because propositional imagining is beside the point, where truth in fiction is concerned; evaluating truth in fiction engages the cognitive architecture in ways that prohibit the mobilization of merely propositional imagination to that end. And second, because it is not obvious, given the strategies usually suggested, that we ever propositionally imagine contradictions in the first place—in fact, it seems we go out of our way to avoid directly imagining them.

Van Rensselaer Potter (1911-2001), le biologiste à l’origine du terme « bioéthique » dans les écrits nord-américains, considère que « real bioethics falls in the context of the ideals of […] Aldo Leopold », un forestier, philosophe et poète ayant marqué le XXe siècle. Associer Leopold à Potter a pour effet de placer la bioéthique dans la famille des éthiques de l’environnement, ce qui la différencie du sens conventionnel retenu en médecine et en recherche depuis le Rapport Belmont (1979), une (...) déclaration ayant propulsé l’institutionnalisation de la bioéthique en Amérique du Nord. Cependant, diviser la bioéthique entre le médical et l’environnemental est réducteur. Potter propose au contraire une bioéthique globale s’intéressant aux enjeux situés à leur interface, dont ceux concernant la terre, la vie sauvage, la surpopulation, la consommation, etc. Cet article vise à amorcer un nouveau chantier d’analyse de la pensée de Potter en s’appuyant sur l’héritage de Leopold en biologie. Une synthèse de cette vision potterienne est proposée de manière à considérer son œuvre comme un tout cohérent s’intégrant aux grands débats qui transcendent les XXe et XXIe siècles. Sa vision apparaît comme une sagesse collective et prospective sous la forme d’une science de la survie et d’un code de bioéthique. Dépassant l’éthique de l’environnement, son association avec Leopold offre un modèle de la complexité s’imposant comme cas indissociable du contexte qui l’englobe, en améliorant nos façons d’intervenir en pratique dans un monde en constante transformation, à titre de gouvernance adaptative et de sagesse de la responsabilité.

En supposant que les manifestations antiracistes des 2 et 13 juin 2020 aient été l’occasion d’une prise de conscience du racisme structurel par les populations majoritaires, notamment en ce qui concerne les violences policières, cet article pose la question de son mécanisme. Le retentissement des manifestations de juin, sur les réseaux sociaux comme dans les « grands » médias, laisserait penser que c’est principalement en fournissant matière à une importante résonance médiatique qu’elles ont permis aux populations majoritaires de prendre conscience (...) du racisme structurel. Mais cette impression est trompeuse : comme l’ont bien montré plusieurs travaux nord-américains sur le sujet, les milieux sociaux fréquentés par les populations majoritaires ne leur permettent pas de remettre en question les habitus qui président aux pratiques responsables du racisme structurel, dans un processus de socialisation que ni la presse, ni la radio, ni la télévision ne sont à même de contrecarrer. Du point de vue de la lutte contre le racisme, il semble plutôt que l’enjeu des manifestations de juin tienne moins à leur résonance médiatique qu’au rôle socialisateur qu’elles ont joué pour les membres des populations majoritaires qui y ont participé : ces manifestations leur ont enfin permis de fréquenter, par deux fois, un milieu susceptible de les pousser à corriger certaines des dispositions qui président aux pratiques responsables du racisme structurel – les multiples charges policières et jets de gaz lacrymogènes ont notamment été l’occasion d’une expérience de terrain riche d’enseignements pour des populations largement disposées à ne voir en la violence policière qu’une violence méritée et/ou anecdotique. -/- Mots-clés : Racisme structurel ; mobilisations antiracistes ; populations majoritaires ; résonance médiatique ; habitus ; resocialisation émancipatrice.

Schopenhauer’s invective is legendary among philosophers, and is unmatched in the historical canon. But these complaints are themselves worthy of careful consideration: they are rooted in Schopenhauer’s philosophy of language, which itself reflects the structure of his metaphysics. This short chapter argues that Schopenhauer’s vitriol rewards philosophical attention; not because it expresses his critical take on Fichte, Hegel, Herbart, Schelling, and Schleiermacher, but because it neatly illustrates his philosophy of language. Schopenhauer’s epithets are not merely spiteful slurs; instead, they reflect (...) deep-seated theoretical and methodological commitments to transparency of exposition. (shrink)

Art historians and philosophers often talk about the interpretive significance of titles, but few have bothered with their historical origins. This omission has led to the assumption that an artwork's title is its proper name, since names and titles share the essential function of facilitating reference to their bearers. But a closer look at the development of our titling practices shows a significant point of divergence from standard analyses of proper names: the semantic content of a title is often crucial (...) to the identification, individuation, and interpretation of its associated artwork. This paper represents a first step towards an empirically centred study of our titling practices. I argue that, in order to accept titles as proper names, we must first recognize the social, rather than the referential, function of naming. (shrink)

It is not uncommon for art historians and philosophers of art to deride the kinds of aesthetic experiences tourists seek out by characterizing them as bowing to the will of the herd, succumbing to peer pressure, or simply seeking out what is popular. Two charges, in particular, tend to be levelled against tourists. The first, which I call the motivation problem, contends that tourists are motivated to seek out aesthetic experiences for the wrong kinds of reasons. The second, which I (...) call the appreciation problem, maintains that tourist tastes are aesthetically uninformed and are thus the inauthentic product of aesthetic luck. But there is a better way of thinking about aesthetic tourism, one that can capture both the tourist’s motivations and the role of aesthetic luck. I argue that aesthetic tourists, like many experts, subscribe to the acquaintance principle, and that doing so generates aesthetic obligations to their practical identity. The tourist, in the end, is no more – and no less – a product of aesthetic luck than the expert connoisseur. (shrink)

Functional diversity holds the promise of understanding ecosystems in ways unattainable by taxonomic diversity studies. Underlying this promise is the intuition that investigating the diversity of what organisms actually do—i.e. their functional traits—within ecosystems will generate more reliable insights into the ways these ecosystems behave, compared to considering only species diversity. But this promise also rests on several conceptual and methodological—i.e. epistemic—assumptions that cut across various theories and domains of ecology. These assumptions should be clearly addressed, notably for the sake (...) of an effective comparison and integration across domains, and for assessing whether or not to use functional diversity approaches for developing ecological management strategies. The objective of this contribution is to identify and critically analyze the most salient of these assumptions. To this aim, we provide an “epistemic roadmap” that pinpoints these assumptions along a set of historical, conceptual, empirical, theoretical, and normative dimensions. (shrink)

It is often thought that the boundaries and properties of art-kinds are determined by the things we say and think about them. More recently, this tendency has manifested itself as concept-descriptivism, the view that the reference of art-kind terms is fixed by the ontological properties explicitly or implicitly ascribed to art and art-kinds by competent users of those terms. Competent users are therefore immune from radical error in their ascriptions; the result is that the ontology of art must begin and (...) end with conceptual analysis. Against this tendency towards concept-driven ontology, I offer a trio of objections derived from: the cultural and temporal variability of concepts of art, the systematic tendency, on the part of would-be ontological assessors, to err on the side of familiar categories or, conversely, to exaggerate minor differences between familiar and unfamiliar practices, and the influence artworld precedents exert over expert and folk concepts alike. These considerations, I argue, mandate an epistemic humility that is simply unavailable to the concept-descriptivist. (shrink)

Although the character of the “lady detective”is a staple of the cozy mystery genre, we contend that there are no great lady detectives to rival Holmes or Poirot. This is not because there are no clever or interesting lady detective characters, but ratherbecause the concept of greatness is sociallyconstructed and, like coolness, depends on public acclaim and perception. We explore the mechanics of genre formation, arguing that the very structure of cozy mysteries precludes female greatness. To create a “great”character,theauthor cannot (...) just endowher with certain attributes; she must actively work to overcome her audience’s tendency to import structures of oppression into the story, and she must wrestle against the conventions of the genre. In doing so, however, authors risk setting their stories in a wholly different genre. (shrink)

In 2018, the Art Gallery of Ontario retitled a painting by Emily Carr which contained an offensive word. Controversy ensued, with some arguing that unsanctioned changes to a work’s title infringe upon artists’ moral and free speech rights. Others argued that such a change serves to whitewash legacies of racism and cultural genocide. In this paper, I show that these concerns are unfounded. The first concern is not supported by law or the history of our titling practices; and the second (...) concern misses the mark by ignoring the gallery’s substantial efforts to avoid just such an outcome. Picking up on a suggestion from Loretta Todd, I argue that we can use Aboriginal Title as a model for thinking about the harms perpetuated by cultural appropriation, and the practices we should adopt to mitigate them.

In France, some institutions seem to call for the engineer’s sense of social responsibility. However, this call is scarcely heard. Still, engineering students have been given the opportunity to gain a general education through courses in literature, law, economics, since the nineteenth century. But, such courses have long been offered only in the top ranked engineering schools. In this paper, we intend to show that the wish to increase engineering students’ social responsibility is an old concern. We also aim at (...) highlighting some macro social factors which shaped the answer to the call for social responsibility in the French engineering “Grandes Ecoles”. In the first part, we provide an overview of the scarce attention given to the engineering curriculum in the scholarly literature in France. In the second part, we analyse one century of discourses about the definition of the “complete engineer” and the consequent role of non technical education. In the third part, we focus on the characteristics of the corpus which has been institutionalized. Our main finding is that despite the many changes which occurred in engineering education during one century, the “other formation” remains grounded on a non academic “way of knowing”, and aims at increasing the reputation of the schools, more than enhancing engineering students’ social awareness.

A critical reflection on John Woods's new monograph, Truth in Fiction – Rethinking its Logic. I focus in particular on Woods’s world-inheritance thesis (what others have variously called ‘background,’ ‘the principle of minimal departure,’ and ‘the reality assumption,’ and which replaces Woods’s earlier ‘fill-conditions’) and its interplay with auctorial say-so, arguing that world-inheritance actually constrains auctorial say-so in ways Woods has not anticipated.

Attempting art: an essay on intention-dependenceIt is a truism among philosophers that art is intention-dependent—that is to say, art-making is an activity that depends in some way on the maker's intentions. Not much thought has been given to just what this entails, however. For instance, most philosophers of art assume that intention-dependence entails concept-dependence—i.e. possessing a concept of art is necessary for art-making, so that what prospective artists must intend is to make art. And yet, a mounting body of anthropological (...) and art-historical evidence and philosophical argument suggests that not only is such a criterion unsatisfied by most of the art-historical canon, but it also rests on a false premise: concepts of 'art' are not shared between cultures, nor even in the same culture across time. My dissertation aims to rectify this error by first exploring what our commitment to art's intention-dependence actually entails, and then showing that, properly understood, intention-dependence sets a number of important constraints on theories of art with respect to explanatory desiderata such as the success- and failure-conditions of art-attempts, the cross-cultural identification of art, and the reference of 'art' and art-kind terms. I begin by situating art's intention-dependence in the philosophical literature on intentional action, arguing that, properly conceived, intention-dependence is a weak criterion which can be satisfied either directly or indirectly. It therefore does not necessarily entail concept-dependence. I then use this distinction to motivate a new treatment of the success- and failure-conditions for art-attempts, arguing that the extant model's emphasis on compliance with 'the manner intended' is far too restrictive to capture actual artistic practices. I go on to show that Ruth Millikan's model of linguistic conventions supplies an independently plausible explanation of art's concept-independent origins in terms of the development of a system of indirectly intention-dependent conventions called an 'artworld'. I argue that this account of artworld development supplies us with the tools we need to distinguish art-kinds from other artifactual kinds. Finally, I turn my attention to methodological issues, arguing that even though 'art' is a social kind with its roots in arbitrary and historically-contingent networks of conventions, the philosophy of art is not merely an exercise in bare conceptual analysis. In fact, there is now a great deal of evidence to show that the ways we think about 'art' are inconsistent, incomplete, imperialistic, and largely unprincipled. Yet I argue that this does not mean that the artworld data have no bearing on theories of art. Instead, I argue that our best reflective understanding of our artworld practices sets the constraints on the reference of 'art' and art-kind terms. I argue that we have no privileged epistemic access to the ontology of social kinds; our only privilege lies in our ability to determine the proper subject of our inquiries. (shrink)

This paper examines the debate as to whether something can have final value in virtue of its relational (i.e., non-intrinsic) properties, or, more briefly put, whether final value must be intrinsic. The paper adopts the perspective of the fitting-attitude analysis (FA analysis) of value, and argues that from this perspective, there is no ground for the requirement that things may have final value only in virtue of their intrinsic properties, but that there might be some grounds for the alternate requirement (...) that final value be grounded only in the essential properties of their bearers. First, the paper introduces the key elements of the FA analysis, and sets aside an obvious but unimportant way in which this analysis makes all final values relational. Second, it discusses some classical counterexamples to the view that final value must be intrinsic. Third, it discusses the relation between final, contributive, and signatory value. Fourth, it examines Zimmerman’s defense of the requirement that final value must be intrinsic on the grounds that final value cannot be derivative. And finally, it explores the alternative requirement that something may have final value in virtue of its essential properties. (shrink)

Cette étude cherche à rendre compte d’un trait particulier et pratiquement inobservé dans la fondation gadamérienne de l’herméneutique philosophique. Si l’on connaît bien le rôle du platonisme — et plus spécifiquement du dialogue platonicien — parmi les sources au sein desquelles Gadamer a puisé pour formuler le caractère dialogique du comprendre, on a rarement noté que la phénoménologie du dialogue sur laquelle s’appuie une telle fondation s’inscrivait en faux par rapport à son modèle sur un point bien précis : l’ironie, (...) qu’elle soit socratique ou platonicienne. Nous proposons ici que pour bien expliquer la relation trouble que la fondation dialogique de l’herméneutique gadamérienne entretient avec l’ironie socratico-platonicienne, il faille concevoir le platonisme de Gadamer à la lumière d’une certaine forme d’aristotélisation, par laquelle la philia et la phronêsis aristotéliciennes sont en quelque sorte projetées sur le modèle platonicien du dialogue.

A review of Thomas Wartenberg's Thoughtful Images: Illustrating Philosophy Through Art (OUP 2023).

In 2006, David Carrier (Carrier, 2006, Museum Skepticism: A History of the Display of Art in Public Galleries. Durham: Duke University Press.) coined the term ‘museum skepticism’ to describe the idea that moving artworks into museum settings strips them of essential facets of their meaning; among art historians, this is better known as ‘decontextualization’, ‘denaturing’, or ‘museumization’. Although they do not usually name it directly, many contemporary debates in the philosophy of art are informed by an inclination towards museum skepticism, (...) from work on aesthetic cognitivism (Feagin, Susan, 1995, “Paintings and their places” Australasian Journal of Philosophy 73.2: 260-8.) and contextualism (Danto, Arthur C., 1988, “Artifact and Art”, in ART/ARTIFACT: African Art in Anthropological Collections. Exhibition Catalogue. New York: Center for African Art and Prestel Verlag, 18-32.) to cultural appropriation (Eaton, A. W. and Gaskell, Ivan, 2009, “Do subaltern artifacts belong in art museums?,” The Ethics of Cultural Appropriation, ed. James O. Young and Conrad Brunk, Oxford and Malden, Mass.: Wiley-Blackwell, 235-67), street art (Baldini, Andrea, 2016, “Street Art: A Reply to Riggle” Journal of Aesthetics and Art Criticism 74.2: 187-91), and the value of authenticity (Korsmeyer, Carolyn, 2016, “Real Old Things” British Journal of Aesthetics, 56.3: 219-31). The very first museum skeptic, however, was Antoine Chrysostôme Quatremère de Quincy (1755-1849). (shrink)

À propos de : Catherine et Raphaël Larrère, Penser et agir avec la nature : Une enquête philosophique, Paris, La Découverte, 2015. -/- L’idée d’une nature sauvage à protéger des avancées techniques ne prend en compte ni la complexité des artefacts, ni ce qu’implique aujourd’hui la protection de la nature. En mettant l’accent sur la notion de biodiversité, C. et R. Larrère cherchent à donner un nouveau fondement à l’écologie politique.
