Natural selection is commonly seen not just as an explanation for adaptive evolution, but as the inevitable consequence of “heritable variation in fitness among individuals”. Although it remains embedded in biological concepts, such a formalisation makes it tempting to explore whether this precondition may be met not only in life as we know it, but also in other physical systems. This would imply that these systems are subject to natural selection and may perhaps be investigated in a biological framework, where (...) properties are typically examined in light of their putative functions. Here we relate the major questions that were debated during a three-day workshop devoted to discussing whether natural selection may take place in non-living physical systems. We start this report with a brief overview of research fields dealing with “life-like” or “proto-biotic” systems, where mimicking evolution by natural selection in test tubes stands as a major objective. We contend the challenge may be as much conceptual as technical. Taking the problem from a physical angle, we then discuss the framework of dissipative structures. Although life is viewed in this context as a particular case within a larger ensemble of physical phenomena, this approach does not provide general principles from which natural selection can be derived. Turning back to evolutionary biology, we ask to what extent the most general formulations of the necessary conditions or signatures of natural selection may be applicable beyond biology. In our view, such a cross-disciplinary jump is impeded by reliance on individuality as a central yet implicit and loosely defined concept. Overall, these discussions thus lead us to conjecture that understanding, in physico-chemical terms, how individuality emerges and how it can be recognised, will be essential in the search for instances of evolution by natural selection outside of living systems.

In 1826, the Pasha of Egypt offered to the King Charles X an unusual present: a living giraffe. While offering remarkable animals was a common practice among monarchs, the choice of a giraffe was somewhat extraordinary since it was the first representative of its kind to set foot in France. The Royal Menagerie of the Paris Muséum national d'histoire naturelle was asked to oversee the transportation of this precious mammal and Étienne Geoffroy Saint-Hilaire, one of its professors, was sent to (...) Marseilles to fetch it on foot all the way back to the capital. The whereabouts of this exotic procession stirred passions throughout the country, generating a fashion craze "à la girafe." The so-called Pasha's giraffe, King's giraffe or French giraffe is also -- and perhaps more importantly -- Geoffroy's giraffe. The giraffe episode is representative of Geoffroy's larger scientific career. Because of its Egyptian flavor, its adventurous aspect, its political and diplomatic undertones, as well as the popular attention and educational opportunities it afforded, that mission was ideally suited for the flamboyant naturalist. So close were the animal's and the French zoologist's fates, that they passed away a couple months apart and both fell into relative oblivion. But even dead and dissected, Geoffroy's giraffe could not easily be dissociated from its companion. The afterlife of its "saintly" relics mirrors the popular and scholarly revival of Étienne Geoffroy Saint-Hilaire, portrayed by some as a forgotten "prophet.". (shrink)

This study undertakes a reading of Etienne de La Boétie’s Discours de la servitude volontaire, endeavoring to bring to light the way it convergences with and diverges from the political thought of Paul Ricœur, around the central concept of the will. On the basis of the twin notions of “denaturation” and of “pathology,” a course unfolds which aims at helping establish the people, in comparison with the institution of the State, through a political process revitalised by friendship. But the (...) two thinkers differ when it comes to the resources of the will. This is reflected in the notion of freedom, conceived as absolute in La Boetie, while Ricœur emphasizes its contingency, which leads him to thematize it in terms of capabilities. (shrink)

Philosophe et penseur du politique, intellectuel marxiste et militant communiste, enseignant, directeur de collection... : à travers le rayonnement de son oeuvre et de sa personne, Louis Althusser a renouvelé la théorie politique et la philosophie de l'histoire, de Machiavel à Marx. Parmi ses contemporains, Michel Foucault exhorte : " Ouvrez les livres d'Althusser! ", Jacques Derrida évoque " la force rayonnante et provocante de sa pensée ", Gilles Deleuze salue l'" Althusser's Band ", et pour Roland Barthes, " le (...) seul modèle acceptable de la science est celui mis au jour par les études d'Althusser sur Marx ". Aliocha Wald Lasowski converse avec vingt écrivains et philosophes qui ont lu, rencontré, parfois travaillé avec Althusser, quand ils n'ont pas fait partie de ses proches. Où l'on mesure à quel point la pensée d'Althusser demeure d'une actualité brûlante. (shrink)

Etienne Balibar, Olivier Bloch, Jean-Claude Bourdin, Isabelle Garo, Alain Gigandet, Pascale Gillot, Annie Ibrahim, Irène Pereira et André Tosel se penchent dans cet ouvrage sur les problèmes et les perpectives induites par le matérialisme althusserien. " Jamais un coup de dés n'abolira le hasard ". Althusser fait un bref commentaire de cette célèbre sentence mallarméenne dans un texte de 1982 - Le courant souterrain du matérialisme de la rencontre. II y conclut que l'histoire n'est que la révocation permanente (...) du fait accompli par le "fait à accomplir" sans qu'on sache à l'avance ni jamais, ni où, ni comment. Affaire de jeu de dés à jeter sur la table vide...

De fait, les catégories du sujet, de l'aliénation, de la dialectique, de l'idéologie, sont bradées ou ébranlées au profit du processus hasardeux et de la vicissitude des formes. Pourtant, ni le primat de la lutte des classes ni la thèse de la matérialité objective du monde ne sont sacrifiés au nouvel horizon de la conjoncture. Il se peut qu'il y ait deux voies du matérialisme, aussi légitimes l'une que l'autre - matérialisme de la nécessité et matérialisme de la rencontre. Gageons que ce dernier puisse faire que les éléments vivants d'un ensemble politique"s'accrochent " entre eux et au tout de telle sorte que ce qui est vrai en théorie le soit aussi en pratique.

First published in French in 2010, _Equaliberty_ brings together essays by Étienne Balibar, one of the preeminent political theorists of our time. The book is organized around _equaliberty_, a term coined by Balibar to connote the tension between the two ideals of modern democracy: equality and liberty. He finds the tension between these different kinds of rights to be ingrained in the constitution of the modern nation-state and the contemporary welfare state. At the same time, he seeks to keep rights (...) discourse open, eschewing natural entitlements in favor of a deterritorialized citizenship that could be expanded and invented anew in the age of globalization. Deeply engaged with other thinkers, including Arendt, Rancière, and Laclau, he posits a theory of the polity based on social relations. In _Equaliberty_ Balibar brings both the continental and analytic philosophical traditions to bear on the conflicted relations between humanity and citizenship. (shrink)

We present a theoretical framework bearing on the evolution of written communication. We analyze writing as a special kind of graphic code. Like languages, graphic codes consist of stable, conventional mappings between symbols and meanings, but (unlike spoken or signed languages) their symbols consist of enduring images. This gives them the unique capacity to transmit information in one go across time and space. Yet this capacity usually remains quite unexploited, because most graphic codes are insufficiently informative. They may only be (...) used for mnemonic purposes or as props for oral communication in real-time encounters. Writing systems, unlike other graphic codes, work by encoding a natural language. This allows them to support asynchronous communication in a more powerful and versatile way than any other graphic code. Yet, writing systems will not automatically unlock the capacity to communicate asynchronously. We argue that this capacity is a rarity in non-literate societies, and not so frequent even in literate ones. Asynchronous communication is intrinsically inefficient because asynchrony constrains the amount of information that the interlocutors share and limits possibilities for repair. This would explain why synchronous, face-to-face communication always fosters the development of sophisticated codes (natural languages), but similar codes for asynchronous communication evolve with more difficulties. It also implies that writing cannot have evolved, at first, for supporting asynchronous communication. (shrink)

This discussion paper responds to two recent articles in Biology and Philosophy that raise similar objections to cultural attraction theory, a research trend in cultural evolution putting special emphasis on the fact that human minds create and transform their culture. Both papers are sympathetic to this idea, yet both also regret a lack of consilience with Boyd, Richerson and Henrich’s models of cultural evolution. I explain why cultural attraction theorists propose a different view on three points of concern for our (...) critics. I start by detailing the claim that cultural transmission relies not chiefly on imitation or teaching, but on cognitive mechanisms like argumentation, ostensive communication, or selective trust, whose evolved or habitual function may not be the faithful reproduction of ideas or behaviours. Second, I explain why the distinction between context biases and content biases might not always be the best way to capture the interactions between culture and cognition. Lastly, I show that cultural attraction models cannot be reduced to a model of guided variation, which posits a clear separation between individual and social learning processes. With cultural attraction, the same cognitive mechanisms underlie both innovation and the preservation of traditions. (shrink)

Evaluative theories of emotions purport to shed light on the nature of emotions by appealing to values. Three kinds of evaluative theories of emotions dominate the recent literature: the judgment theory equates emotions with value judgments; the perceptual theory equates emotions with perceptions of values, and the attitudinal theory equates emotions with evaluative attitudes. This paper defends a fourth kind of evaluative theory of emotions, mostly neglected so far: the reactive theory. Reactive theories claim that emotions are attitudes which arise (...) in reaction to perceptions of value. (shrink)

Cultural forms are constrained by cognitive biases, and writing is thought to have evolved to fit basic visual preferences, but little is known about the history and mechanisms of that evolution. Cognitive constraints have been documented for the topology of script features, but not for their orientation. Orientation anisotropy in human vision, as revealed by the oblique effect, suggests that cardinal orientations, being easier to process, should be overrepresented in letters. As this study of 116 scripts shows, the orientation of (...) strokes inside written characters massively favors cardinal directions, and it is organized in such a way as to make letter recognition easier: Cardinal and oblique strokes tend not to mix, and mirror symmetry is anisotropic, favoring vertical over horizontal symmetry. Phylogenetic analyses and recently invented scripts show that cultural evolution over the last three millennia cannot be the sole cause of these effects. (shrink)

The theory and practice of contemporary comparative biology and phylogeny reconstruction (systematics) emphasizes algorithmic aspects but neglects a concern for the evidence. The character data used in systematics to formulate hypotheses of relationships in many ways constitute a black box, subject to uncritical assessment and social influence. Concerned that such a state of affairs leaves systematics and the phylogenetic theories it generates severely underdetermined, we investigate the nature of the criteria of homology and their application to character conceptualization in the (...) context of transformationist and generative paradigms. Noting the potential for indeterminacy in character conceptualization, we conclude that character congruence (the coherence of character statements) relative to a hierarchy is a necessary, but not a sufficient, condition for phylogeny reconstruction. Specifically, it is insufficient due to the lack of causal grounding of character hypotheses. Conceptualizing characters as homeostatic property cluster natural kinds is in accordance with the empirical practice of systematists. It also accounts for the lack of sharpness in character conceptualization, yet requires character identification and re-identification to be tied to causal processes. (shrink)

Cognitive gadgets puts forward an ambitious claim: language, mindreading, and imitation evolved by cultural group selection. Defending this claim requires more than Heyes' spirited and effective critique of nativist claims. The latest human “cognitive gadgets,” such as literacy, did not spread through cultural group selection. Why should social cognition be different? The book leaves this question pending. It also makes strong assumptions regarding cultural evolution: it is moved by selection rather than transformation; it relies on high‐fidelity imitation; it requires specific (...) cognitive adaptations to cultural learning. Each of these assumptions raises crucial yet unaddressed difficulties. (shrink)

This chapter defends an axiological theory of pain according to which pains are bodily episodes that are bad in some way. Section 1 introduces two standard assumptions about pain that the axiological theory constitutively rejects: (i) that pains are essentially tied to consciousness and (ii) that pains are not essentially tied to badness. Section 2 presents the axiological theory by contrast to these and provides a preliminary defense of it. Section 3 introduces the paradox of pain and argues that since (...) the axiological theory takes the location of pain at face value, it needs to grapple with the privacy, self-intimacy and incorrigibility of pain. Sections 4, 5 and 6 explain how the axiological theory may deal with each of these. (shrink)

The “species-as-individuals” thesis takes species, or taxa, to be individuals. On grounds of spatiotemporal boundedness, any biological entity at any level of complexity subject to evolutionary processes is an individual. From evolutionary theory flows an ontology that does not countenance universal properties shared by evolving entities. If austere nominalism were applied to evolving entities, however, nature would be reduced to a mere flow of passing events, each one a blob in space–time and hence of passing interest only. Yet if there (...) is genuine biodiversity in nature, if nature is genuinely carved into species, and taxa, then these evolutionary entities will be genuinely differentiated into specific kinds, each species being one of its kind. Given the fact that evolving entities have un-sharp boundaries, an appropriately weak, “non-essentialist” concept of natural kind has to be invoked that does not allow for strong identity conditions. The thesis of this paper is that species are not either individuals, or natural kinds. Instead, species are complex wholes (particulars, individuals) that instantiate a specific natural kind.

The history of biological systematics documents a continuing tension between classifications in terms of nested hierarchies congruent with branching diagrams (the ‘Tree of Life’) versus reticulated relations. The recognition of conflicting character distribution led to the dissolution of the scala naturae into reticulated systems, which were then transformed into phylogenetic trees by the addition of a vertical axis. The cladistic revolution in systematics resulted in a representation of phylogeny as a strictly bifurcating pattern (cladogram). Due to the ubiquity of character (...) conflict—at the genetic or morphological level, or at any level in between—some characters will necessarily have to be discarded ( qua noise) in favor of others in support of a strictly bifurcating phylogenetic tree. Pattern analysts will seek maximal congruence in the distribution of characters (ultimately of any kind) relative to a branching tree-topology; process explainers will call such tree-topologies into question by reference to incompatible evolutionary processes. Pattern analysts will argue that process explanations must not be brought to bear on pattern reconstruction; process explainers will insist that the reconstructed pattern requires a process explanation to become scientifically relevant, i.e., relevant to evolutionary theory. The core question driving the current debate about the adequacy of the ‘Tree of Life’ metaphor seems to be whether the systematic dichotomization of the living world is an adequate representation of the complex evolutionary history of global biodiversity. In ‘Questioning the Tree of Life’, it seems beneficial to draw at least four conceptual distinctions: pattern reconstruction versus process explanation as different epistemological approaches to the study of phylogeny; open versus closed systems as expressions of different kinds of population (species) structures; phylogenetic trees versus cladograms as representations of evolutionary processes versus patterns of relationships; and genes versus species as expressions of different levels of causal integration and evolutionary transformation.

Although widely used across psychology, economics, and philosophy, the concept ofeffort is rarely ever defined. This article argues that the time is ripe to look for anexplicit general definition of effort, makes some proposals about how to arrive at thisdefinition, and suggests that a force-based approach is the most promising. Section 1presents an interdisciplinary overview of some chief research axes on effort, and arguesthat few, if any, general definitions have been proposed so far. Section 2 argues thatsuch a definition is (...) now needed and proposes a basic methodology to arrive at it, whosefirst step is to make explicit the various tacit assumptions about effort made acrosssciences and ordinary thinking. Section 3 unearths 4 different conceptions of effortfrom research on effort so far:primitive-feelings accounts,comparator-based accounts,resource-based accountsandforce-based accounts. It is then argued that the first 2kinds of accounts, although interesting in their own right, are not strictly speaking abouteffort. Section 4 considers the 2 most promising general approaches to efforts: re-source-based and force-based accounts. It argues that these accounts are not only compatible but actually extensionally equivalent. This notwithstanding, it explains why force-based accounts should be regarded as more fundamental than resource-basedaccounts -/- . (shrink)

In order to understand the place Max Scheler occupied in the debates of his time around the notion of Europe, this article aims to shed some light on the possible convergences between Max Scheler and Rudolf Eucken, who was his thesis director at Jena. The article begins by outlining Rudolf Eucken's conception of Europe, then it identifies a number of points in common between the two authors, before finally measuring the extent of these convergences in Scheler's conception of Europe. At (...) the end of the discussion, it appears that the reception of Augustinianism and a shared conception of community reveal interesting links between the two authors. This connection will give the twenty-first-century reader a better understanding of the framework in which Max Scheler's reflections on Europe are set. (shrink)

The definition of taxon names as formalized by the PhyloCode is based on Kripke's thesis of “rigid designation” that applies to Millian proper names. Accepting the thesis of “rigid designation” into systematics in turn is based on the thesis that species, and taxa, are individuals. These largely semantic and metaphysical issues are here contrasted with an epistemological approach to taxonomy. It is shown that the thesis of “rigid designation” if deployed in taxonomy introduces a new essentialism into systematics, which is (...) exactly what the PhyloCode was designed to avoid. Rigidly designating names are not supposed to change their meaning, but if the shifting constitution of a clade is thought to cause a shift of meaning of the taxon name, then the taxon name is not a “rigid designator”. Phylogenetic nomenclature either fails to preserve the stability of meaning of taxon names that it propagates, or it is rendered inconsistent with its own philosophical background. The alternative explored here is to conceptualize taxa as natural kinds, and to replace the analytic definition of taxon names by their explanatory definition. Such conceptualization of taxa allows taxon names to better track the results of ongoing empirical research. The semantic as well as epistemic gain is that if taxon names are associated with natural kind terms instead of being proper names, the composition of the taxon will naturally determine the meaning of its name.

The paper aims at clarifying the distinctions and relations between pain and suffering. Three negative theses are defended: 1. Pain and suffering are not identical. 2. Pain is not a species of suffering, nor is suffering a species of pain, nor are pain and suffering of a common (proximate) genus. 3. Suffering cannot be defined as the perception of a pain’s badness, nor can pain be defined as a suffered bodily sensation. Three positive theses are endorsed: 4. Pain and suffering (...) are categorically distinct: pain is a localised bodily episode, suffering is a non-localised affective attitude. 5. Suffering can be expressed, pains cannot. As a consequence, we can have compassion for the suffering of others, not for their pains. 6. The relation between pain and suffering is akin to the relation between danger and fear, injustice and indignation, wrongdoing and guilt: suffering is the correct reaction to pain. One upshot is that both the influential view that the experience of pain is incorrigible and the influential view that the ordinary conception of pain is paradoxical are false. (shrink)

This paper defends hedonic intentionalism, the view that all pleasures, including bodily pleasures, are directed towards objects distinct from themselves. Brentano is the leading proponent of this view. My goal here is to disentangle his significant proposals from the more disputable ones so as to arrive at a hopefully promising version of hedonic intentionalism. I mainly focus on bodily pleasures, which constitute the main troublemakers for hedonic intentionalism. Section 1 introduces the problem raised by bodily pleasures for hedonic intentionalism and (...) some of the main reactions to it. Sections 2 and 3 rebut two main approaches equating bodily pleasures with non- intentional episodes. More precisely, section 2 argues that bodily pleasures cannot be purely non-intentional self-conscious feelings, by relying on Brentano’s objection to Hamilton’s theory of pleasure. Section 3 argues that bodily pleasures cannot be non-intentional sensory qualities by relying on Brentano’s objections to Stumpf’s theory of pleasure. Section 4 develops a brentanian view of the intentionality of bodily pleasures by claiming bodily pleasures are directed at a sui generis class of sensory qualities. Section 5 presents an objection to Brentano’s later theory of pleasure according to which all sensory pleasures are directed at sensing acts. (shrink)

An ideography is a general-purpose code made of pictures that do not encode language, which can be used autonomously – not just as a mnemonic prop – to encode information on a broad range of topics. Why are viable ideographies so hard to find? I contend that self-sufficient graphic codes need to be narrowly specialized. Writing systems are only an apparent exception: At their core, they are notations of a spoken language. Even if they also encode nonlinguistic information, they are (...) useless to someone who lacks linguistic competence in the encoded language or a related one. The versatility of writing is thus vicarious: Writing borrows it from spoken language. Why is it so difficult to build a fully generalist graphic code? The most widespread answer points to a learnability problem. We possess specialized cognitive resources for learning spoken language, but lack them for graphic codes. I argue in favor of a different account: What is difficult about graphic codes is not so much learning or teaching them as getting every user to learn and teach the same code. This standardization problem does not affect spoken or signed languages as much. Those are based on cheap and transient signals, allowing for easy online repairing of miscommunication, and require face-to-face interactions where the advantages of common ground are maximized. Graphic codes lack these advantages, which makes them smaller in size and more specialized. (shrink)

The thesis defended, the “guise of the ought”, is that the formal objects of desires are norms (oughts to be or oughts to do) rather than values (as the “guise of the good” thesis has it). It is impossible, in virtue of the nature of desire, to desire something without it being presented as something that ought to be or that one ought to do. This view is defended by pointing to a key distinction between values and norms: positive and (...) negative norms (obligation and interdiction) are interdefinable through negation; positive and negative values aren’t. This contrast between the norms and values, it is argued, is mirrored, within the psychological realm, by the contrast between the desires and emotions. Positive and negative desires are interdefinable through negation, but positive and negative emotions aren’t. The overall, Meinongian picture suggested is that norms are to desires what values are to emotions. (shrink)

Species are generally considered to be the basic units of evolution, and hence to constitute spatio-temporally bounded entities. In addition, it has been argued that species also instantiate a natural kind. Evolution is fundamentally about change. The question then is how species can remain the same through evolutionary change. Proponents of the species qua individuals thesis individuate species through their unique evolutionary origin. Individuals, or spatio-temporally located particulars in general, can be bodies, objects, events, or processes, or a combination of (...) these. It is here argued that species are best understood as open or closed, causally integrated processual systems that also instantiate an historically conditioned homeostatic property cluster natural kind.

Ingvar Johansson has argued that there are not only determinate universals, but also determinable ones. I here argue that this view is misguided by reviving a line of argument to the following effect: what makes determinates falling under a same determinable similar cannot be distinct from what makes them different. If true, some similarities — imperfect similarities between simple determinate properties — are not grounded in any kind of property-sharing. I suggest that determinables are better understood as maximal disjunctions of (...) brutely and imperfectly similar determinates. Such brute similarities have been thought to clash with realism about universals. I argue that this worry stems from the mistaken assumption that perfect and imperfect similarities are relations of a same kind. If exact and inexact resemblances are distinct and heterogeneous explananda, the realist about universals might explain the first thanks to property-sharing, while happily leaving imperfect similarities between properties unexplained.

The German tradition of considering species, and higher taxonomic entities, as individuals begins with the temporalization of natural history, thus pre-dating Darwin’s ‘Origin’ of 1859. In the tradition of German Naturphilosophie as developed by Friedrich Schelling, species came to be seen as parts of a complex whole that encompasses all (living) nature. Species were comprehended as dynamic entities that earn individuality by virtue of their irreversible passage through time. Species individuality was conceived in terms of species taxa forming a spatiotemporally (...) located relational system (complex whole), a conception of species that was easily assimilated to an evolutionary world view. However, the dynamics of an evolutionary process driven by variation and natural selection created a tension between continuity in nature as opposed to the discreteness and relative stasis of species. As a consequence, some authors such as Ernst Haeckel and Karl August Möbius denied the reality of species, while others explicitly linked the reality and individuality of species to their temporal duration. The mature conception of species as individuals, as formulated by Ludwig von Bertalanffy and adopted by Willi Hennig, is one of an historically conditioned, spatiotemporally located, causally integrated, dynamic yet transiently homeostatically stabilized relational system.

This paper describes and defends the “virtues of ingenuity”: detachment, lucidity, thoroughness. Philosophers traditionally praise these virtues for their role in the practice of using reasoning to solve problems and gather information. Yet, reasoning has other, no less important uses. Conviction is one of them. A recent revival of rhetoric and argumentative approaches to reasoning (in psychology, philosophy and science studies) has highlighted the virtues of persuasiveness and cast a new light on some of its apparent vices—bad faith, deluded confidence, (...) confirmation and myside biases. Those traits, it is often argued, will no longer look so detrimental once we grasp their proper function: arguing in order to persuade, rather than thinking in order to solve problems. Some of these biases may even have a positive impact on intellectual life. Seen in this light, the virtues of ingenuity may well seem redundant. Defending them, I argue that the vices of conviction are not innocuous. If generalized, they would destabilize argumentative practices. Argumentation is a common good that is threatened when every arguer pursues conviction at the expense of ingenuity. Bad faith, myside biases and delusions of all sorts are neither called for nor explained by argumentative practices. To avoid a collapse of argumentation, mere civil virtues (respect, humility or honesty) do not suffice: we need virtues that specifically attach to the practice of making conscious inferences.

We sometimes experience pleasures and displeasures simultaneously: whenever we eat sfogliatelle while having a headache, whenever we feel pain fading away, whenever we feel guilty pleasure while enjoying listening to Barbara Streisand, whenever we are savouring a particularly hot curry, whenever we enjoy physical endurance in sport, whenever we are touched upon receiving a hideous gift, whenever we are proud of withstanding acute pain, etc. These are examples of what we call " mixed feelings ". Mixed feelings are cases in (...) which one and the same person experiences pleasure and displeasure at the same time. Mixed feelings raise two questions: (1) If pleasure and displeasure are contraries, how can mixed feelings be possible? (2) Does the excess of pleasure (or displeasure) that we feel when experiencing mixed feelings itself constitute a new feeling, that results from the co-occurrence of the first two? I will argue (1) that mixed feelings are possible and that their existence does not threaten the contrariety of pleasure and displeasure, and (2) that there are no resultant feelings: having a lot of pleasure and a little displeasure does not result in having additional mild pleasure. Finally, I will suggest (3) that although both false, scepticism towards the existence of mixed feelings, as well as the idea according to which resultant feelings exist, are inspired from a single and correct idea: that pleasure and displeasure do fuse in some cases.

Taking its clues from Popperian philosophy of science, cladistics adopted a number of assumptions of the empiricist tradition. These include the identification of a dichotomy between observation reports and theoretical statements and its subsequent abandonment on the basis of the insight that all observation reports are theory-laden. The neglect of the ‘context of discovery’, which is the step of theory (hypothesis) generation. The emphasis on coherentism in the ‘context of justification’, which is the step of evaluation of the relative merits (...) of alternative theories. The appeal to a total evidence approach in phylogenetic inference. And finally, a silence about causation, which results in an instrumentalist approach to phylogeny reconstruction. This paper explores how these empiricist assumptions are embedded in phylogenetic systematics, and why these assumptions are problematic for cladists (or any taxonomists). (shrink)

Brentano’s theory of continuity is based on his account of boundaries. The core idea of the theory is that boundaries and coincidences thereof belong to the essence of continua. Brentano is confident that he developed a full-fledged, boundary-based, theory of continuity1; and scholars often concur: whether or not they accept Brentano’s take on continua they consider it a clear contender. My impression, on the contrary, is that, although it is infused with invaluable insights, several aspects of Brentano’s account of continuity (...) remain inchoate. To be clear, the theory of boundaries on which it relies, as well as the account of ontological dependence that Brentano develops alongside his theory of boundaries, constitute splendid achievements. However, the passage from the theory of boundaries to the account of continuity is rather sketchy. This paper pinpoints some chief problems raised by this transition, and proposes some solutions to them which, if not always faithful to the letter of Brentano’s account of continua, are I believe faithful to its spirit. §1 presents Brentano’s critique of the mathematical account of the continuous. §2 introduces Brentano’s positive account of continua. §3 raises three worries about Brentano’s account of continuity. §4 proposes a Neo-Brentanian approach to continua that handles these worries.

In a recent contribution, Ereshefsky (2007a) maintained the following points against Nixon and Carpenter (2000), Keller et al. (2003), and Rieppel (2005a, 2006a,b): (1) that species and taxa are individuals, not natural kinds; (2) that “origin essentialism” conflates qualitative essentialism with genealogical connectedness; and (3) that rigid designation theory applies to taxon names. Here I argue that: (1) the conception of species as individuals or natural kinds is not mutually exclusive but rather context sensitive; species are best seen as spatio-temporally (...) located processual systems that instantiate an HPC natural kind; (2) “origin essentialism” is problematic because of the fuzzy boundaries of species and taxa, yet required if rigid designation theory is to apply to taxon names; and (3) the theories of direct reference and rigid designation do not apply to taxon names.

This paper explores the use of Popper's philosophy of science by cladists in their battle against evolutionary and numerical taxonomy. Three schools of biological systematics fiercely debated each other from the late 1960s: evolutionary taxonomy, phenetics or numerical taxonomy, and phylogenetic systematics or cladistics. The outcome of that debate was the victory of phylogenetic systematics/cladistics over the competing schools of thought. To bring about this "cladistic turn" in systematics, the cladists drew heavily on the philosopher K.R. Popper in order to (...) dress up phylogenetic systematics as a hypothetico-deductivist, indeed falsificationist, research program that would put an end to authoritarianism. As the case of the "cladistic revolution" demonstrates, scientists who turn to philosophy in defense of a research program read philosophers with an agenda in mind. That agenda is likely to distort the philosophical picture, as happened to Popper's philosophy of science at the hands of cladists. (shrink)

A recently published study on the development of the turtle shell(1) highlights the important role that development plays in the origin of evolutionary novelties(1). The evolution of the highly derived adult anatomy of turtles is a prime example of a macroevolutionary event triggered by changes in early embryonic development. Early ontogenetic deviation may cause patterns of morphological change that are not compatible with scenarios of gradualistic, stepwise transformation.

What is the relationship between cosmopolitanism and secularism—the worldwide and the worldly? While cosmopolitan politics may seem inherently secular, existing forms of secularism risk undermining the universality of cosmopolitanism because they privilege the European tradition over all others and transform particular historical norms into enunciations of truth, valid for all cultures and all epochs. In this book, the noted philosopher Étienne Balibar explores the tensions lurking at this troubled nexus in order to advance a truly democratic and emancipatory cosmopolitanism, which (...) requires a secularization of secularism itself. Balibar argues for the idea of the universal against its particular dominant institutions. He questions the assumptions that underlie popular ideas of secularism and religion and outlines the importance of a new critique for the contemporary world. Balibar holds that conflicts between religious and secular discourses need to be reframed from a point of view that takes into account the cultural hybridization, migration and mobility, and transformation of borders that have reshaped the postcolonial age. Among the topics discussed are the uses and misuses of the category of religion and the religious, the paradoxical genealogy of monotheism, French laïcité’s identitarian turn, and the implications of the responses to the Charlie Hebdo attacks for an extended definition of free speech. Going beyond circumscribed notions of religion and the public sphere, Secularism and Cosmopolitanism is a profound rethinking of identity and difference that seeks to make room for a renewed political imagination.

This paper revitalizes the debate of an ethics of contemporary famine. Famine constitutes a distinct development challenge that has only received moderate public and academic attention. Singer’s Famine Relief Argument from 1972 emphasizing a strong obligation of charitable benevolence towards victims of famine, for example, continues to constitute the dominant ethical principle of famine. The paper argues this revisionary principle still constitutes a strong and convincing ethical argument. However, the dynamics of contemporary famine makes it necessary to expand this ethical (...) obligation outside the realm of pure philanthropy. Concretely, the paper argues for the obligation of criminalizing famine and prosecuting the perpetrators of famine that have either callously allowed famine to unfold or have intentionally created and exacerbated the conditions for famine. While such an obligation is not void of ethical dilemmas, a famine ethics relying on obligations of charity as well as obligations of criminal prosecution constitutes a superior ethical principle for the alleviation of famine.

Le potentiel de développement porté par les TIC reste quelque chose de purement théorique pour des millions de personnes compte tenu de l'existence de la fracture numérique qui sépare les « inforiches » des « infopauvres ». Dans la perspective de la construction d'une société de l'information inclusive, la question de l'accès universel aux TIC est donc centrale, notamment pour les pays africains. Cette problématique ne doit cependant pas être réduite à la question de la disponibilité des infrastructures de télécommunications; (...) elle doit prendre en compte l'accès réel, c'est-à-dire les usages. Afin de résoudre les problèmes de diverses natures interdisant l'appropriation des TIC par le plus grand nombre, il faut aller au-delà de la régulation par le marché et mettre en oeuvre de vigoureuses politiques publiques visant à faire de l'accès universel une réalité concrète pour tous ceux dont les chances de bénéficier pleinement des opportunités offertes par la société de l'information sont aujourd'hui hypothéquées.The potential of ICT-led development remains something purely theoretical for millions of people due to the existence of the digital divide between the "haves" from "have-nots". In view of the construction of the information society inclusive, the issue of universal access to ICTs is central, especially for African countries. This issue should not be reduced to the question of the availability of telecommunications infrastructure, but must take into account the actual access, that is to say, uses. To solve problems of various kinds prohibiting the appropriation of ICTs by the largest number, you must go beyond regulation by the market and implement vigorous public policies to make universal access a reality concrete for all those whose opportunities to benefit fully from the opportunities offered by the information society are now mortgaged.

Can we maintain that purple seems composed of red and blue without giving up the impenetrability of the red and blue parts that compose it? Brentano thinks we can. Purple, according to him, is a chessboard of red and blue tiles which, although individually too small to be perceived, are together indistinctly perceived within the purple. After a presentation of Brentano’s solution, we raise two objections to it. First, Brentano’s solution commits him to unperceivable intentional objects (the chessboard’s tiles). Second, (...) his chessboard account fails in the end to explain the phenomenal spatial continuity of compound colours. We then sketch an alternative account, which, while holding fast to the phenomenal compoundedness of the purple and to the impenetrability of component colours, avoids introducing inaccessible intentional objects and compromising on the continuity of the purple. According to our proposal, instead of being indistinctly perceived spatial parts of the purple, red and blue are distinctly perceived non- spatial parts of it. (shrink)
