E. O. Wilson (1974: 54) describes the problem that social organisms pose: “On what bases do we distinguish the extremely modified members of an invertebrate colony from the organs of a metazoan animal?” This framing of the issue has inspired many to look more closely at how groups of organisms form and behave as emergent individuals. The possible existence of “superorganisms” test our best intuitions about what can count and act as genuine biological individuals and how we should study them. (...) As we will discuss, colonies of certain organisms display many of the properties that we usually reserve only to individual organisms. Although there is good reason to believe that many social insects form genuine emergent biological individuals, the conclusion offered here is of a slightly different sort. I will argue that to understand some social insects' interactions and the emergent traits they give rise to, it may be helpful to shift our understanding from a community-level approach to an ecosystem-level approach. I will argue that viewing certain insect colonies (termites) as parts of ecosystems allows us to better understand some of the adaptations that have emerged from their evolution. (shrink)

We argue that a fashionable interpretation of the theory of natural selection as a claim exclusively about populations is mistaken. The interpretation rests on adopting an analysis of fitness as a probabilistic propensity which cannot be substantiated, draws parallels with thermodynamics which are without foundations, and fails to do justice to the fundamental distinction between drift and selection. This distinction requires a notion of fitness as a pairwise comparison between individuals taken two at a time, and so vitiates the interpretation (...) of the theory as one about populations exclusively.

Ecological fitness has been suggested to provide a unifying definition of fitness. However, a metric for this notion of fitness was in most cases unavailable except by proxy with differential reproductive success. In this article, I show how differential persistence of lineages can be used as a way to assess ecological fitness. This view is inspired by a better understanding of the evolution of some clonal plants, colonial organisms, and ecosystems. Differential persistence shows the limitation of an ensemblist noncausal understanding (...) of evolution. Causal explanations are necessary to understand the evolution by natural selection of these biological systems. †To contact the author write to: Department of Philosophy, University of Montreal, P.O.

Following Wallace’s suggestion, Darwin framed his theory using Spencer’s expression “survival of the fittest”. Since then, fitness occupies a significant place in the conventional understanding of Darwinism, even though the explicit meaning of the term ‘fitness’ is rarely stated. In this paper I examine some of the different roles that fitness has played in the development of the theory. Whereas the meaning of fitness was originally understood in ecological terms, it took a statistical turn in terms of reproductive success throughout (...) the 20th Century. This has lead to the ever-increasing importance of sexually reproducing organisms and the populations they compose in evolutionary explanations. I will argue that, moving forward, evolutionary theory should look back at its ecological roots in order to be more inclusive in the type of systems it examines. Many biological systems can only be satisfactorily accounted for by offering a non-reproductive account of fitness. This argument will be made by examining biological systems with very small or transient population structures. I argue this has significant consequences for how we define Darwinism, increasing the significance of survival over that of reproduction. (shrink)

One of intuitions driving the acceptance of a neat structured tree of life is the assumption that organisms and the lineages they form have somewhat stable spatial and temporal boundaries. The phenomenon of symbiosis shows us that such ‘fixist’ assumptions does not correspond to how the natural world actually works. The implications of lateral gene transfer (LGT) have been discussed elsewhere; I wish to stress a related point. I will focus on lateral function transfer (LFT) and will argue, using examples (...) of what many would call ‘superorganisms’, that the emergence of symbiotic individuals revives the importance of functional and adaptationist thinking in how we conceptualize the lineages of biological individuals. The consequence of the argument is that, if we really want to hold onto tree of life thinking, we had better accept that new saplings appear and disappear all the time. (shrink)

We argue that ecology in general and biodiversity and ecosystem function research in particular need an understanding of functions which is both ahistorical and evolutionarily grounded. A natural candidate in this context is Bigelow and Pargetter’s evolutionary forward-looking account which, like the causal role account, assigns functions to parts of integrated systems regardless of their past history, but supplements this with an evolutionary dimension that relates functions to their bearers’ ability to thrive and perpetuate themselves. While Bigelow and Pargetter’s account (...) focused on functional organization at the level of organisms, we argue that such an account can be extended to functional organization at the community and ecosystem levels in a way that broadens the scope of the reconciliation between ecosystem ecology and evolutionary biology envisioned by many BEF researchers. By linking an evolutionary forward-looking account of functions to the persistence-based understanding of evolution defended by Bouchard and others, and to the theoretical research on complex adaptive systems, we argue that ecosystems, by forming more or less resilient assemblages, can evolve even while they do not reproduce and form lineages. We thus propose a Persistence Enhancing Propensity account of role functions in ecology to account for this overlap of evolutionary and ecological processes. (shrink)

Building upon a non-standard understanding of evolutionary process focusing on variation and persistence, I will argue that communities and ecosystems can evolve by natural selection as emergent individuals. Evolutionary biology has relied ever increasingly on the modeling of population dynamics. Most have taken for granted that we all agree on what is a population. Recent work has reexamined this perceived consensus. I will argue that there are good reasons to restrict the term “population” to collections of monophyletically related replicators and (...) interactors, which explains why many existing models in population biology exclude by definition many genuine evolving biological individuals such as communities and ecosystems. By studying a case of community evolution, we will see that it is variation that is important to evolutionary processes, not populations. Variation within a population is only one of many types of variation that can lead to evolution by natural selection. The upshot of focusing on variation is that cases of community and ecosystem adaptive change become tractable in evolutionary terms. I will show that complex emergent individuals such as communities and ecosystems cannot be fully accommodated by conventional population/reproduction models but can be accommodated by variation/persistence models.

Our intuitive assumption that only organisms are the real individuals in the natural world is at odds with developments in cell biology, ecology, genetics, evolutionary biology, and other fields. Although organisms have served for centuries as nature's paradigmatic individuals, science suggests that organisms are only one of the many ways in which the natural world could be organized. When living beings work together--as in ant colonies, beehives, and bacteria-metazoan symbiosis--new collective individuals can emerge. In this book, leading scholars consider the (...) biological and philosophical implications of the emergence of these new collective individuals from associations of living beings. The topics they consider range from metaphysical issues to biological research on natural selection, sociobiology, and symbiosis. (shrink)

Given the complexity of most phenomena, we have to delegate much epistemic work to other knowers and we must find reasons for relying on these specific knowers and not others. In our societies, these other knowers are often called experts and we rely on their epistemic authority more and more. For many complex phenomena such as climate change, genetically modified crops, and immunization, the experts that are called upon are scientific experts. For that reason, finding good reasons and justification for (...) deferring to their knowledge is of paramount societal importance. As we shall see, many have analyzed this epistemic dependence on scientific experts and have tried to show in what contexts are there good... (shrink)

Philosophers of biology have been absorbed by the problem of defining evolutionary fitness since Darwin made it central to biological explanation. The apparent problem is obvious. Define fitness as some biologists implicitly do, in terms of actual survival and reproduction, and the principle of natural selection turns into an empty tautology: those organisms which survive and reproduce in larger numbers, survive and reproduce in larger numbers. Accordingly, many writers have sought to provide a definition for ‘fitness’ which avoid this outcome. (...) In particular the definition of fitness as a probabilistic propensity has been widely favored.1 Others, recognizing that no definition both correct and complete can actually be provided, have accepted the consequence that the leading principle of the theory is a definitional truth and attempted to mitigate the impact of this outcome for the empirical character of the theory.2 Still others have argued that ‘fitness’ is properly viewed as a term undefined in the theory of natural selection (on the model of mass—a term undefined in Newtonian mechanics).3 But few have contemplated the solution to this problem proposed by Mohan Matthen and André Ariew (hereafter, MA), in..

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)

One important concern regarding implantable Brain Computer Interfaces is the fear that the intervention will negatively change a patient’s sense of identity or agency. In particular, there is concern that the user will be psychologically worse-off following treatment despite postoperative functional improvements. Clinical observations from similar implantable brain technologies, such as deep brain stimulation, show a small but significant proportion of patients report feelings of strangeness or difficulty adjusting to a new concept of themselves characterized by a maladaptive je ne (...) sais quoi despite clear motor improvement. Despite the growing number of cases in the DBS literature, there is currently no accepted or standardized tool in neuroethics specifically designed to capture the phenomenological postoperative experience of patients implanted with DBS or BCI devices. Given potential risks of postoperative maladaptation, it is important for the field of neuroethics to develop a qualitative instrument that can serve as a shared method for capturing postoperative variations in patient experience of identity and agency. The goal of this article is to introduce an instrument we have developed for this purpose and call for further neuroethical efforts to assess the phenomenology of implantable brain device use.

Peu de textes de Pascal semblent relever de l'expérience ou du discours mystique. Outre le Mémorial, qui garde mémoire d'une expérience de Dieu sur une feuille de papier, outre la Prière pour demander à Dieu le bon usage des maladies, certaines lettres à Mlle de Roannez contiennent des conseils pour se rapprocher de Dieu, et d'autres lettres spirituelles, comme celle écrite après la mort de son père, traitent de l'attitude du chrétien face à la mort. L'Ecrit sur la conversion du (...) pécheur nous livre les difficultés de l'homme à la recherche de Dieu. Cependant, malgré la pauvreté quantitative des textes traitant assez clairement de la mystique, il nous est apparu qu'elle constitue la clé de voûte de l'édifice pascalien, sans laquelle l'oeuvre de Pascal ne fait pas sens. A partir de ce point ultime et transcendant, expliqué en partie par le contexte familial et social de Pascal, on peut relire et comprendre sa démarche scientifique, et la relation entretenue avec la Bible. Ainsi nous proposons une relecture de l'intégralité de l'oeuvre pascalienne, en la replaçant dans l'histoire de la mystique judéo-chrétienne, et en mettant notamment en relief la façon dont Pascal s'est approprié l'esprit et la mystique bibliques, dans une tradition où l'influence du dualisme platonicien n'est pas étrangère. La mystique pascalienne se définit ainsi comme le désir d'une union à Dieu, médiatisée par la figure du Christ, et il en résulte une relation de chaque instant, où l'homme se sent transformé, déifié, dans un sentiment de joie.

This article addresses the conditions that are necessary for non-Indigenous people to learn from Indigenous people, more specifically from women and feminists. As non-Indigenous scholars, we first explore the challenges of epistemic dialogue through the example of Traditional Ecological Knowledge. From there, through the concept of mastery, we examine the social and ontological conditions under which settler subjectivities develop. As demonstrated by Julietta Singh and Val Plumwood, the logic of mastery—which has legitimated the oppression and exploitation of Indigenous peoples—has been (...) reproduced in academia, leaving almost no room for Indigenous knowledge and epistemes. In the same vein, Sámi scholar Rauna Kuokkanen reclaims and suggests the logic of the gift as a means to render academia more hospitable to Indigenous peoples and epistemes. In our view, reclaim as a concept-practice is a promising way to disrupt colonial, racist, and sexist power relations. Thus, we in turn propose to reclaim vulnerability as defined by Judith Butler in order to deconstruct masterful settler subjectivities and reconstruct relational ones instead. As theorized by Erinn Gilson, we propose epistemic vulnerability to imagine the conditions of our learning from Indigenous peoples and philosophies. (shrink)

For many epistemologists and normativity theorists, epistemic norms necessarily entail normative reasons. Why or in virtue of what do epistemic norms have this necessary normative authority? According to what I call epistemic constitutivism, it is ultimately because belief constitutively aims at truth. In this paper, I examine various versions of the aim of belief thesis and argue that none of them can plausibly ground the normative authority of epistemic norms. I conclude that epistemic constitutivism is not a promising strategy for (...) grounding epistemic normativity. (shrink)

According to moral error theorists, moral claims necessarily represent categorically or robustly normative facts. But since there are no such facts, moral thought and discourse are systematically mistaken. One widely discussed objection to the moral error theory is that it cannot be true because it leads to an epistemic error theory. We argue that this objection is mistaken. Objectors may be right that the epistemic error theory is untenable. We also agree with epistemic realists that our epistemological claims are not (...) systematically in error. However, this is not because there are robustly normative facts, but rather because the truth of our epistemic claims doesn’t turn on whether there are such facts. Epistemic facts, we argue, are not robustly or categorically normative. Moral error theorists should therefore respond to the objection that their view does not commit them to the epistemic error theory. (shrink)

What is the source of epistemic normativity? In virtue of what do epistemic norms have categorical normative authority? According to epistemic teleologism, epistemic normativity comes from value. Epistemic norms have categorical authority because conforming to them is necessarily good in some relevant sense. In this article, I argue that epistemic teleologism should be rejected. The problem, I argue, is that there is no relevant sense in which it is always good to believe in accordance with epistemic norms, including in cases (...) where the matter at hand is completely trivial. Therefore, if epistemology is normative, its normativity won't come from value. (shrink)

According to epistemic instrumentalism, epistemic normativity arises from and depends on facts about our ends. On that view, a consideration C is an epistemic reason for a subject S to Φ only if Φ-ing would promote an end that S has. However, according to the Too Few Epistemic Reasons objection, this cannot be correct since there are cases in which, intuitively, C is an epistemic reason for S to Φ even though Φ-ing would not promote any of S’s ends. After (...) clarifying both EI and the Too Few Epistemic Reasons objection, I examine three major instrumentalist replies and argue that none of them is satisfactory. I end by briefly sketching a fourth possible response, which is, I suggest, more promising than the other three. (shrink)

Epistemic instrumentalism views epistemic norms and epistemic normativity as essentially involving the instrumental relation between means and ends. It construes notions like epistemic normativity, norms, and rationality, as forms of instrumental or means-end normativity, norms, and rationality. I do two main things in this paper. In part 1, I argue that there is an under-appreciated distinction between two independent types of epistemic instrumentalism. These are instrumentalism about epistemic norms and instrumentalism about epistemic normativity. In part 2, I argue that this (...) under-appreciated distinction matters for the debate surrounding the plausibility of EI. Specifically, whether we interpret EI as norm-EI or as source-EI matters for the widely discussed universality or categoricity objection to EI, and for two important motivations for adopting EI, namely naturalism and the practical utility of epistemic norms. I will then conclude by drawing some lessons for epistemic instrumentalism going forward. (shrink)

Un calcul logique, au sens large, est une méthode de résolution appliquée au traitement d'une structure propositionnelle. Les propositions constituant cette structure peuvent aussi bien être des expressions d'une langue naturelle (comme le français) que des expressions d'un langage formalisé (comme l'arithmétique), liées entre elles par une dépendance de nature fonctionnelle. Cet ouvrage constitue une introduction à deux outils de calcul en logique du premier ordre, soit le calcul en arbres de consistance et le calcul en déduction naturelle. La première (...) partie, centrée sur la notion de structure propositionnelle, expose les concepts, les objets et les méthodes propres à la logique propositionnelle. Dans la deuxième partie, la logique propositionnelle est étendue à la logique prédicative au moyen de la quantification et de concepts caractéristiques d'un langage du premier ordre. Les deux outils de calcul sont ensuite enrichis de manière à pouvoir traiter des fonctions propositionnelles, soit des prédicats du premier ordre.De nombreux exemples et exercices, accompagnés de leurs solutions, aideront l'étudiant à progresser vers des calculs toujours plus complexes et à raffiner ses méthodes de calcul logique.

Epistemology is widely seen as a normative discipline like ethics. Just like moral facts, epistemic facts – i.e. facts about our beliefs’ epistemic justification, rationality, reasonableness, correctness, warrant, and the like – are standardly viewed as normative facts. Yet, whereas many philosophers have rejected the existence of moral facts, few have raised similar doubts about the existence of epistemic facts. In recent years however, several metaethicists and epistemologists have rejected this Janus-faced or dual stance towards the existence of moral and (...) epistemic facts. As recent developments in metaethics and normativity theory have made clear, objections to the existence of moral facts really are metanormative objections that target the existence of normative facts more generally. But since epistemic facts are no less normative than moral facts, the argument goes, the existence of the former is equally threatened by metaethical objections. In this thesis, I argue that this rejection of the dual stance fails because epistemic facts are not normative facts. Although they imply norms, they do not imply genuine normativity since the epistemic norms of belief that they imply lack necessary normative authority or force. Unlike moral norms and just like e.g. norms of etiquette and the law, there is not automatically a normative reason to conform to epistemic norms. Therefore, even if metaethical objections target all normative facts, it does not follow that they also target epistemic facts. I offer a two-part abductive argument in favour of that conclusion. First, I argue that epistemic facts lack five commonly cited features of normative facts (but not of merely norm-implying facts). Then, I argue that this is best explained by the thesis that epistemic facts are merely norm-implying and not genuinely normative. I end by exploring the potential consequences of this conclusion for epistemology and metaethics. (shrink)

According to epistemic deontologism, attributions of epistemic justification are deontic claims about what we ought to believe. One of the most prominent objections to this conception, due mainly to William P. Alston, is that the principle that ‘ought’ implies ‘can’ rules out deontologism because our beliefs are not under our voluntary control. In this paper, I offer a partial defense of Alston’s critique of deontologism. While Alston is right that OIC rules out epistemic deontologism, appealing to doxastic involuntarism is not (...) necessary for generating that tension. Deontologists would still have a problem with OIC if doxastic voluntarism turned out to be true or if deontologism did not require voluntarism. This is because, in short, epistemic justification does not imply ‘can’. If, as deontologists maintain, epistemic justification implies ‘oughts’, then epistemic justification must also imply ‘can’ given OIC. But since epistemic justification does not imply ‘can’, OIC dictates that we reject deontologism. I end by exploring the possible consequences of this incompatibility between OIC and deontologism. My conclusion is that at least one of the following claims must be true. Either ‘ought’ does not imply ‘can’, attributions of epistemic justification are not deontic claims, or epistemic claims lack necessary or categorical normative authority. (shrink)

The unlivable is the most extreme point of human suffering and injustice. But what is it exactly? How do we define the unlivable? And what can we do to prevent and repair it? These are the intriguing questions Judith Butler and Frédéric Worms discuss in a captivating dialogue situated at the crossroads of contemporary life and politics. Here, Judith Butler criticizes the norms that make life precarious and unlivable, while Frédéric Worms appeals to a "critical vitalism" as a way of (...) allowing the hardship of the unlivable to reveal what is vital for us. For both Butler and Worms, the difference between the livable and the unlivable forms the critical foundation for a contemporary practice of care. Care and support, in all their aspects, make human life livable, that is, "more than living." To understand it, we must draw on the concrete practices of humans who are confronted with the unlivable: the refugees of today and the witnesses and survivors of past violations and genocide. They teach us what is intolerable but also undeniable about the unlivable, and what we can do to resist it. Crafted with critical rigor, mutual respect, and lively humor, the compelling dialogue transcribed and translated in this book took place at the École Normale Supérieure (ENS) on April 11, 2018, at a time when close to two thousand migrants were living in nearby makeshift camps in northern Paris. The Livable and the Unlivable showcases this 2018 dialogue in the context of Butler's and Worms's ongoing work and the evolution of their thought, as presented by Laure Barillas and Arto Charpentier in their equally engaging introduction. It concludes with a new afterword that addresses the crises unfolding in our world and the ways a philosophically rigorous account of life must confront them. While this book will be of keen interest to readers of philosophy and cultural criticism, and those interested in vitalism, new materialism, and critical theory, it is a far from merely academic text. In the conversation between Butler and Worms, we encounter questions we all grapple with in confronting the distress and precarity of our times, marked as it is by types of survival that are unlivable, from concentration camps to prisons to environmental toxicity, to forcible displacement, to the Covid pandemic. The Livable and the Unlivable at once considers longstanding philosophical questions around why and how we live, while working to retrieve a philosophy of life for today's Left. (shrink)
