Although contemporary metaphysics has recently undergone a neo-Aristotelian revival wherein dispositions, or capacities are now commonplace in empirically grounded ontologies, being routinely utilised in theories of causality and modality, a central Aristotelian concept has yet to be given serious attention – the doctrine of hylomorphism. The reason for this is clear: while the Aristotelian ontological distinction between actuality and potentiality has proven to be a fruitful conceptual framework with which to model the operation of the natural world, the distinction between (...) form and matter has yet to similarly earn its keep. In this chapter, I offer a first step toward showing that the hylomorphic framework is up to that task. To do so, I return to the birthplace of that doctrine - the biological realm. Utilising recent advances in developmental biology, I argue that the hylomorphic framework is an empirically adequate and conceptually rich explanatory schema with which to model the nature of organisms.

A systematic theory of naturalism, bridging metaphysics and the science of complexity and emergence.

According to enactivism all living systems, from single cell organisms to human beings, are ontologically endowed with some form of teleological and sense-making agency. Furthermore, enactivists maintain that: there is no fixed pregiven world and as a consequence all organisms “bring forth” their own unique “worlds” through processes of sense-making. The first half of the paper takes these two ontological claims as its central focus and aims to clarify and make explicit the arguments and motivations underlying them. Our analysis here (...) highlights three distinct but connected problems for enactivism: these arguments do not and cannot guarantee that there is no pregiven world, instead, they end up generating a contradiction whereby a pregiven world seems to in fact be tacitly presupposed by virtue of a reliance on a tacit epistemic perspectivalism which is also inherently representationalist and as a consequence makes it difficult to satisfactorily account for the ontological plurality of worlds. Taking these considerations on board, the second half of the paper then aims to develop a more robust ontologically grounded enactivism. Drawing from biosemiotic enactivism, science and technology studies and anthropology, the paper aims to present an account which both rejects a pregiven world and coherently accounts for how organisms bring forth ontologically multiple worlds.

Research on animal behavior is typically organized according to a combination of two influential frameworks: Ernst Mayr’s distinction between proximate and ultimate causes, and Niko Tinbergen’s “four questions”. My aim is to debunk two common interpretive misconceptions about Mayr’s proximate–ultimate distinction and its relationship to Tinbergen’s four questions, and to offer a new interpretation that avoids both. The first misconception is that the proximate–ultimate distinction maps cleanly onto Tinbergen’s four questions, marking a boundary between Tinbergen’s evolutionary and survival value questions (...) versus developmental and mechanistic questions. The second is that Mayr’s proximate–ultimate distinction is meant to rule out the relevance of proximate causes to evolutionary explanations. I argue that neither is plausible given the text and Mayr’s philosophical aims, namely, to argue that evolutionary biology cannot be reduced to either the physical sciences or to other areas of biology. Through a reconstruction of Mayr’s anti-reductionist argument, I develop an interpretation according to which the proximate–ultimate distinction marks two ways that teleological reasoning can be naturalistically grounded in biology, corresponding to Mayr’s distinction between teleonomic and adapted systems. Mayr distinguishes reduction, which the proximate–ultimate distinction is meant to block, from analysis, through which he allows that proximate causes, causes that are neither proximate nor ultimate, and chance can all contribute to evolutionary explanations. I conclude by suggesting some ways in which the interpretation defended here reframes our understanding of Mayr’s disagreements with some evolutionary-developmental biologists. (shrink)

In this expansive and highly original two-volume work, Jim Behuniak reformulates John Dewey's late-period "Cultural turn" and proposes that its next logical step is an "intra-Cultural philosophy" that goes beyond what is commonly known as "comparative philosophy." Each volume models itself on this new approach, arguing that early Chinese thought is poised to join forces with Dewey in meeting an urgent cultural need: namely, helping the Western tradition to correct its outdated Greek-medieval assumptions, especially where these result in pre-Darwinian inferences (...) about the world. Relying on the latest findings in Chinese philosophy, these volumes establish "specific philosophical relationships" between Dewey's ideas and early Chinese thought for this purpose, showing how together they can assist us in getting our thinking "back in gear" with the world as it is currently known through the biological, physical, and cognitive sciences. Volume One: Dao and Nature engages Dewey with themes generally associated with "Daoism," and includes discussion of the organization of organic form, teleology, cosmology, knowledge, the body, and technology. Volume One thus works to establish "Chinese natural philosophy" as an empirical framework in which to consider the cultural-level phenomena examined in Volume Two: Dao and Culture. (shrink)

Teleology has a complicated history in the biological sciences. Some have argued that Darwin’s theory has allowed biology to purge itself of teleological explanations. Others have been content to retain teleology and to treat it as metaphorical, or have sought to replace it with less problematic notions like teleonomy. And still others have tried to naturalize it in a way that distances it from the vitalism of the nineteenth century, focusing on the role that function plays in teleological explanation. No (...) consensus has seemed possible in this debate. This paper takes a different approach. It argues that teleology is a perfectly acceptable scientific notion, but that the debate took an unfortunate misstep some 2300 years ago, one that has confused things ever since. The misstep comes in the beginning of Aristotle’s Physics when a distinction is made between two types of teleological explanation. One type pertains to artifacts while the other pertains to entities in nature. For Aristotle, artifacts are guided by something external to themselves, human intentions, while natural entities are guided by an internal nature. We aim to show that there is, in fact, only one type of legitimate teleological explanation, what Aristotle would have considered a variant of an artifact model, where entities are guided by external fields. We begin with an analysis of the differences between the two types of explanation. We then examine some evidence in Aristotle’s biological works suggesting that on account of his natural-artifactual distinction, he encountered difficulties in trying to provide teleological accounts of spontaneous generation. And we show that it is possible to resolve these difficulties with a more robust version of an artifact model of teleology, in other words, with an externalist teleology. This is McShea’s model, in which goal-directed entities are guided by a nested series of upper-level fields. To explain teleological behavior, this account invokes only external physical forces rather than mysterious internal natures. We then consider how field theory differs from other efforts to naturalize teleology in biology. And finally, we show how the account enables us to grapple with certain difficult cases – genes and intentions – where, even in biology today, the temptation to posit internal natures remains strong.

Evolutionary developmental biology represents a paradigm shift in the understanding of the ontogenesis and evolutionary progression of the denizens of the natural world. Given the empirical successes of the evo-devo framework, and its now widespread acceptance, a timely and important task for the philosophy of biology is to critically discern the ontological commitments of that framework and assess whether and to what extent our current metaphysical models are able to accommodate them. In this paper, I argue that one particular model (...) is a natural fit: an ontology of dispositional properties coherently and adequately captures the crucial casual-cum-explanatory role that the fundamental elements of evo-devo play within that framework.

The advent of contemporary evolutionary theory ushered in the eventual decline of Aristotelian Essentialism (Æ) – for it is widely assumed that essence does not, and cannot have any proper place in the age of evolution. This paper argues that this assumption is a mistake: if Æ can be suitably evolved, it need not face extinction. In it, I claim that if that theory’s fundamental ontology consists of dispositional properties, and if its characteristic metaphysical machinery is interpreted within the framework (...) of contemporary evolutionary developmental biology, an evolved essentialism is available. The reformulated theory of Æ offered in this paper not only fails to fall prey to the typical collection of criticisms, but is also independently both theoretically and empirically plausible. The paper contends that, properly understood, essence belongs in the age of evolution. (shrink)

Illuminating study of the ideas and influences of a near-forgotten American philosopher.

The traditional practice of establishing morphological types and investigating morphological organization has found new support from evolutionary developmental biology (evo-devo), especially with respect to the notion of body plans. Despite recurring claims that typology is at odds with evolutionary thinking, evo-devo offers mechanistic explanations of the evolutionary origin, transformation, and evolvability of morphological organization. In parallel, philosophers have developed non-essentialist conceptions of natural kinds that permit kinds to exhibit variation and undergo change. This not only facilitates a construal of species (...) and higher taxa as natural kinds, but also broadens our perspective on the diversity of kinds found in biology. There are many different natural kinds relevant to the investigative and explanatory aims of evo-devo, including homologues and developmental modules. (shrink)

In identifying intrinsic molecular chance and extrinsic adaptive pressures as the only causally relevant factors in the process of evolution, the theoretical perspective of the Modern Synthesis had a major impact on the perceived tenability of an ontology of dispositional properties. However, since the late 1970s, an increasing number of evolutionary biologists have challenged the descriptive and explanatory adequacy of this “chance alone, extrinsic only” understanding of evolutionary change. Because morphological studies of homology, convergence, and teratology have revealed a space (...) of possible forms and phylogenetic trajectories that is considerably more restricted than expected, evo-devo has focused on the causal contribution of intrinsic developmental processes to the course of evolution. Evo-devo’s investigation into the developmental structure of the modality of morphology – including both the possibility and impossibility of organismal form – has led to the utilisation of a number of dispositional concepts that emphasise the tendency of the evolutionary process to change along certain routes. In this sense, and in contrast to the perspective of the Modern Synthesis, evo-devo can be described as a “science of dispositions.” This chapter discusses the recent philosophical literature on dispositional properties in evo-devo, exploring debates about both the metaphysical and epistemological aspects of the central dispositional concepts utilised in contemporary evo-devo and addressing the epistemological question of how dispositional properties challenge existing explanatory models in evolutionary biology.

As a practicing life scientist, Descartes must have a theory of what it means to be a living being. In this paper, I provide an account of what his theoretical conception of living bodies must be. I then show that this conception might well run afoul of his rejection of final causal explanations in natural philosophy. Nonetheless, I show how Descartes might have made use of such explanations as merely hypothetical, even though he explicitly blocks this move. I conclude by (...) suggesting that there is no reason for him to have blocked the use of hypothetical final causes in this way. (shrink)

This Element focuses on three challenges of evolution to religion: teleology, human origins, and the evolution of religion itself. First, religious worldviews tend to presuppose a teleological understanding of the origins of living things, but scientists mostly understand evolution as non-teleological. Second, religious and scientific accounts of human origins do not align in a straightforward sense. Third, evolutionary explanations of religion, including religious beliefs and practices, may cast doubt on their justification. We show how these tensions arise and offer potential (...) responses for religion. Individual religions can meet these challenges, if some of their metaphysical assumptions are adapted or abandoned.

The paper introduces the problem of unawareness into multi-dimensional Principal–Agent theory. We introduce two key parameters to describe the problem, the extent and the effect of unawareness, show under what conditions it is optimal for the Principal to propose an incomplete or a complete contract, and characterize the incentive power of optimal linear contracts. If Agents differ in their unawareness, optimal incentive schemes can be distorted for both aware and unaware Agents, because, different from standard contract theory, the single-crossing property (...) fails to hold. In this case, even aware Agents can be subject to inefficiently high or low incentives. (shrink)

Evolutionary adaptation has been suggested as the hallmark of life that best accounts for life’s creativity. However, current evolutionary approaches still fail to give an adequate account of it, even if they are able to explain both the origin of novelties and the proliferation of certain traits in a population. Although modern-synthesis Darwinism is today usually appraised as too narrow a position to cope with all the complexities of developmental and structural biology—not to say biosemiotic phenomena—, Darwinism need not be (...) if we separate metaphor from reality in natural selection in order to show the axiological complexity of this concept. This can shed light on the relationship between biosemiotics and biological evolution. (shrink)

Williams argued that Darwin replaced teleology by natural selection. This article argues that this idea is based on a misunderstanding of Darwin’s critique of the argument from design. Darwin did not replace teleology by evolutionary explanations but showed that we can understand teleology without referring to a Designer. He eliminated the concept of design and rehabilitated Aristotelian teleological explanations. The implication is that adaptations should not be investigated as if designed, but with the help of both teleological and evolutionary explanations. (...) It is argued that elaborations of teleological explanations enable us to reconcile evolutionary theory and other fields in science. (shrink)

The notion of biological function is fraught with difficulties—intrinsically and irremediably so, we argue. The physiological practice of functional ascription originates from a time when organisms were thought to be designed and remained largely unchanged since. In a secularized worldview, this creates a paradox which accounts of functions as selected effect attempt to resolve. This attempt, we argue, misses its target in physiology and it brings problems of its own. Instead, we propose that a better solution to the conundrum of (...) biological functions is to abandon the notion altogether, a prospect not only less daunting than it appears, but arguably the natural continuation of the naturalisation of biology.

The mental realm seems different to the physical realm; the mental is thought to be dependent on, yet distinct from the physical. But how, exactly, are the two realms supposed to be different, and what, exactly, creates the seemingly insurmountable juxtaposition between the mental and the physical? This review identifies and discusses five marks of the mental, features that set characteristically mental phenomena apart from the characteristically physical phenomena. These five marks (intentionality, consciousness, free will, teleology, and normativity) are not (...) presented as a set of features that define mentality. Rather, each of them is something we seem to associate with phenomena we consider mental, and each of them seems to be in tension with the physical view of reality in its own particular way. It is thus suggested how there is no single mind-body problem, but a set of distinct but interconnected problems. Each of these separate problems is analyzed, and their differences, similarities and connections are identified. This provides a useful basis for future theoretical work on psychology and philosophy of mind, that until now has too often suffered from unclarities, inadequacies, and conflations. (shrink)

On dit souvent que, tandis que la biologie de l'évolution utilise un concept étiologique de fonction (la fonction d'un trait biologique n'est autre que son effet sélectionné), la physiologie prend appui sur un autre concept de fonction, celui de rôle causal. Cependant, un examen plus attentif montre que le concept non normatif de rôle causal n'est pas ce dont la physiologie générale ou la neurophysiologie ont besoin. Ces disciplines font un large usage de notions comme celles de bon fonctionnement, de (...) fonctionnement normal, de fonctionnement perturbé ou de trouble fonctionnel. Il semble ainsi qu'un concept normatif comme le concept étiologique n'est pas seulement utile dans le contexte d'explications téléologiques ou évolutionnistes, mais aussi dans celui d'explications mécanistes ou opérationnelles telles qu'elles sont couramment proposées par la physiologie. La différence entre types d'explication n'est pas une différence entre deux concepts de fonction. En particulier, l'analyse physiologique serait une tâche impossible si elle devait prendre en compte toutes les relations causales à l'intérieur de l'organisation fonctionnelle de chaque système biologique. Pour résoudre ce problème, la physiologie doit être une analyse du fonctionnement normal du système, quelle que soit la part d'idéalisation nécessaire. La notion de bon fonctionnement, conçu comme le produit de l'histoire évolutive, nous aide en particulier à comprendre pourquoi les systèmes qui fonctionnent bien se ressemblent, et pourquoi les systèmes qui dysfonctionnent peuvent le faire de tant de façons différentes. It is often claimed that although evolutionary biology uses an etiological concept of function (according to etiological theory, the function of a biological feature is its selected effect), physiology relies on a different concept of function, the causal role concept. However, upon closer scrutiny, it appears that the non-normative causal role concept is not what is needed by physiology or neurophysiology. These disciplines make a wide use of normative notions like proper functioning, normal functioning, impaired functioning, or functional disorders. In this case, it seems that a normative concept like the etiological concept is not only useful in the context of teleological or evolutionary explanations, but also in the context of mechanical or operational explanations as they are routinely offered by physiology. The difference between types of explanations is not a difference between two kinds of concepts of function. In particular, physiological analysis would be an impossible task if it had to take into account all causal links within the functional organization of each biological system. To solve this problem, physiology has to be the analysis of the proper or normal functioning of the system, even if normal functioning is usually obtained through a process of idealization. The notion of proper functioning, conceived as the product of evolutionary history, helps us understand, among other things, why properly functioning systems tend to be similar, and why malfunctioning systems may differ in so many different ways.

This paper argues that a minimal notion of function and a notion of normal-proper function are used in explaining how bodies and brains operate. Neither is Cummins’ notion, as originally defined, and yet his is often taken to be the clearly relevant notion for such an explanatory context. This paper also explains how adverting to normal-proper functions, even if these are selected functions, can play a significant scientific role in the operational explanations of complex systems that physiologists and neurophysiologists provide, (...) despite a lack of relevant causal efficacy on the part of such functions.

Both Aristotle and Ernst Mayr present theories of dual explanation in biology, with proximal, clearly physical explanations and more distal, biology-specific explanations. Aristotle’s presentation of final cause explanations in Posterior Analytics relates final causes to the necessary material, formal, and efficient causes that mediate them. Johnson and Leunissen demonstrate the problematic nature of historical and recent interpretations and open the door for a new interpretation consistent with modern evolutionary theory. Mayr’s differentiation of proximate and ultimate/evolutionary causes provides a key to (...) appropriating Aristotle for modern use, if care is taken to differentiate Mayr’s proximate/distal and mechanical/evolutionary distinctions from his intentional/non-intentional distinction. Building on Mayr, and noting his appropriation of ancient and recent commentary, a strong case can be made for nested explanation, wherein evolutionary explanations are instantiated in systems of mechanical explanations. Biological concepts of organism, gene, function, etc., are etiologically prior to mechanical explanations of function, but temporally posterior to mechanical explanations of historical adaptation. Such an analysis sheds light on recent arguments within evolutionary biology while highlighting the importance of epistemology in contemporary science. (shrink)

The primary challenge for generating a useful scientific definition of life comes from competing concepts of biological activity and our failure to make them explicit in our models. I set forth a three-part scheme for characterizing definitions of life, identifying a binary , a range , and a preference . The three components together form a proper activity in biology . To be clear, I am not proposing that proper activity be adopted as the best definition of life or even (...) as a desirable definition for life. Instead, I am arguing that some notion of proper activity already exists within common scientific definitions. By making the implicit elements explicit, the notion can be analyzed to see whether it is useful and appropriate in the context of the biological sciences. (shrink)

Following the revival in the last decades of the concept of “organism”, scholarly literature in philosophy of science has shown growing historical interest in the theory of Immanuel Kant, one of the “fathers” of the concept of self-organisation. Yet some recent theoretical developments suggest that self-organisation alone cannot fully account for the all-important dimension of autonomy of the living. Autonomy appears to also have a genuine “interactive” dimension, which concerns the organism’s functional interactions with the environment and does not simply (...) derive from its internal organisation. Against this background, we focus on a family of natural philosophical approaches that historically have already strongly taken in account this aspect of autonomy, notably going beyond Kant’s perspective on self-organisation. We thus review Hegel, Plessner, and Jonas’ different perspectives on living beings, focussing in particular on four points: the distinction between organic and inorganic, the theory of biological organisation, the processuality of the living, and the “boundary” between inside and outside, through which the organism establishes its relationship to the environment. We, then, compare the three perspectives on these four points, and finally address the question of what advantages their contribution present—especially compared to Kant’s theory—with respect to the topic of organism’s autonomy. This could help—we hope—to better understand what is at the stake still today. (shrink)

How shall we understand apparently teleological systems? What explains their persistence and their plasticity? Here I argue that all seemingly goal-directed systems—e.g., a food-seeking organism, human-made devices like thermostats and torpedoes, biological development, human goal seeking, and the evolutionary process itself—share a common organization. Specifically, they consist of an entity that moves within a larger containing structure, one that directs its behavior in a general way without precisely determining it. If so, then teleology lies within the domain of the theory (...) of compositional hierarchies. (shrink)

A theory may be invalid, not owing to erroneous observations or the invocation of an inappropriate law, but because of the use of equivocal terms. This is demonstrated for Darwin's failed model of sympatric speciation through the principle of divergence.

The question concerning the meaning of life is important, but it immediately confronts the present authors with insurmountable obstacles from a philosophical standpoint, as it would require us to define not only what we hold to be life, but what we hold to be meaning in addition, requiring us to do both in a properly researched context. We unconditionally surrender to that challenge. Instead, we offer a vernacular, armchair approach to life’s origin and meaning, with some layman’s thoughts on the (...) meaning of origins as viewed from the biologist’s standpoint. One can observe that biologists generally approach the concept of biological meaning in the context of evolution. This is the basis for the broad resonance behind Dobzhansky’s appraisal that “Nothing in biology makes sense except in the light of evolution”. Biologists try to understand living things in the historical context of how they arose, without giving much thought to the definition of what life or living things are, which for a biologist is usually not an interesting question in the practical context of daily dealings with organisms. Do humans generally understand life’s meaning in the context of history? If we consider the problem of life’s origin, the question of what constitutes a living thing becomes somewhat more acute for the biologist, though not more answerable, because it is inescapable that there was a time when there were no organisms on Earth, followed by a time when there were, the latter time having persisted in continuity to the present. This raises the question of where, in that transition, chemicals on Earth became alive, requiring, in turn, a set of premises for how life arose in order to conceptualize the problem in relation to organisms we know today, including ourselves, which brings us to the point of this paper: In the same way that cultural narratives for origins always start with a setting, scientific narratives for origins also always start with a setting, a place on Earth or elsewhere where we can imagine what happened for the sake of structuring both the problem and the narrative for its solution. This raises the question of whether scientific origins settings convey meaning to humans in that they suggest to us from what kind of place and what kinds of chemicals we are descended, that is, to which inanimate things we are most closely related.

The paper examines the ramifications of naturalism with regard to the question of individuality in economics and biology. Economic theory has to deal with whether households, firms, and states are individuals or are mere entities such as clubs, networks, and coalitions. Biological theory has to deal with the same question with regard to cells, organisms, family packs, and colonies. To wit, the question of individuality in both disciplines involves three separate problems: the metaphysical, phenomenist, and ontological. The metaphysical problem is (...) concerned with purposeful action: Is the firm or organism exclusively the product of efficient causality (optimization) or is it motivated by final causality (purposefulness)? The phenomenist problem is interested in the substantiality of essences: Is the firm''s or organism''s scheme of institutions/traits deep or is it extraneous to identity? The ontological problem is related to the issue of reductionism: Is the behavior of lower-level organization governed by a pre-constituted entities or is it context-sensitive? The paper finds that theoretical differences run along the naturalist/anti-naturalist divide rather than along disciplinary specialization. Also, the paper finds that it is not inconsistent for the same theorist to be naturalist with regard to one problem and anti-naturalist with respect to the other two problems. (shrink)

This paper uses a game-theoretic framework to formalize the Hayekian notion of equilibrium as the compatibility of plans. To do so, it imposes more structure on the conventional model of strategic games. For each player, it introduces goals, goal-oriented strategies, and the goals’ probabilities of success, from which players’ payoffs are derived. The differences between the compatibility of plans and Nash equilibrium are identified and discussed. Furthermore, it is shown that the notion of compatibility of plans, in general, differs from (...) the notion of Pareto efficiency. Since the compatibility of plans across all players can rarely be achieved in reality, a measurement is introduced to determine various degrees of plan compatibility. Several possible extensions and applications of the model are discussed. (shrink)

Structurally, cognitive and biological evolution are highly similar. Random variation and constant but blind selection drive evolution within biology as well as within cognition. However, evolution of cognitive programs, and in particular of grammar systems, is not a subclass of biological evolution but a domain of its own. The abstract evolutionary principles, however, are akin in cognitive and biological evolution. In other words, insights gained in the biological domain can be cautiously applied to the cognitive domain. This paper claims that (...) the cognitively encapsulated, i.e. consciously inaccessible, aspects of grammars as cognitively represented systems, that is, the procedural and structural parts of grammars, are subject to, and results of, Darwinian evolution, applying to a domain-specific cognitive program. Other, consciously accessible aspects of language do not fall under Darwinian evolutionary principles, but are mostly instances of social changes. (shrink)

This dissertation focuses on teleology and functions in biology. More precisely, it focuses on the scientific legitimacy of teleofunctional attributions and explanations in biology. It belongs to a multi-faceted debate that can be traced back to at least the 1970s. One aspect of the debate concerns the naturalization of functions. Most authors try to reduce, translate or explain functions and teleology in terms of efficient causes so that they find their place in the framework of the natural sciences. Our approach (...) here is radically different, as we question the premise that teleological explanations are disguised causal explanations. On the contrary, we defend that they are acceptable in natural sciences and in biology in particular. We challenge the idea that teleological explanations are immature causal explanations, as well as the idea that teleology and functions are some sort of intentional explanations. We therefore reject the accusations of anthropomorphism, vitalism and finalism. On the contrary, we defend that teleology, causality and intentionality correspond to different, autonomous and complementary modes of representation of the outside world. -/- ———[FRANÇAIS]——— -/- Ce travail de thèse porte sur la téléologie et les fonctions en biologie. Plus précisément, il porte sur la légitimité scientifique des attributions et des explications téléofonctionnelles en biologie. Il s’inscrit dans le cadre d’un débat à plusieurs facettes que l’on peut faire remonter au moins jusqu’aux années 1970 et qui est encore très actif aujourd’hui. L’un des aspects du débat porte sur la naturalisation des fonctions, c’est-à-dire sur la manière de les réduire, de les traduire ou de les expliciter en termes de causes efficientes de sorte qu’elles trouvent leur place dans le cadre des sciences de la nature. Notre approche ici est radicalement différente, car nous remettons en question la prémisse selon laquelle les explications téléologiques seraient des explications causales déguisées. Nous défendons au contraire qu’elles sont acceptables en tant que telles aussi bien de façon générale que dans le domaine scientifique et en particulier en biologie. De façon générale, nous remettons en question l’idée selon laquelle la pensée téléologique serait une pensée causale immature, ainsi que sa dépendance présumée vis-à-vis de la psychologie, c’est-à-dire de l’intentionnalité. Nous rejetons donc les accusations d’anthropomorphisme, de vitalisme et de finalisme formulées contre elle. Nous défendons au contraire que la téléologie, la causalité et l’intentionnalité correspondent à des modes différents, autonomes et complémentaires de représentation du monde extérieur. (shrink)

Al netto di alcune eccezioni, non si può certo affermare che la concezione kantiana dell’organismo abbia rappresentato un modello frequente per le spiegazioni del funzionamento dell’organismo nella filosofia della biologia del ventesimo e del ventunesimo secolo.

In this talk I present the main results from Anta (2021), namely, that the theoretical division between Boltzmannian and Gibbsian statistical mechanics should be understood as a separation in the epistemic capabilities of this physical discipline. In particular, while from the Boltzmannian framework one can generate powerful explanations of thermal processes by appealing to their microdynamics, from the Gibbsian framework one can predict observable values in a computationally effective way. Finally, I argue that this statistical mechanical schism contradicts the Hempelian (...)

Finality, design and purpose have started to be excluded from the language of the natural sciences since the XVIIth century. Darwin succeeded in excluding them from his theory of evolution appealing to a blind and mechanical natural selection. Today, the most usual definitions for the concept of biological function take for granted that functions: 1) are not dependent on a goal; 2) are not dependent on observers, but only on nature; 3) are explicable in causal terms, either with reference to (...) the causal history of the organ (etiological definition), or with reference to its present structure and causal capabilities (dispositional definition). However, we shall see that such presuppositions cannot take into account the normative character of the concept of biological function. We show that a generalization of the concept of scientific objectivity lets us affirm that functions: 1’) are dependent on a goal; 2’) are dependent on both observers and nature; 3’) cannot be reduced to causality, nor break the laws of physics; and yet, 4) are truly objective.

The contemporary philosophy of mind and neuroethics are two of the liveliest fields of interdisciplinary reflection which deal with the everlasting topic: what/who we essentially are. One of the many questions that can be tackled in order to go deep in this knowledge is: why man is naturally inclined towards specific tiers for survival which constitute his/her teleological project of flourishing? Two different, but complementary, answers are brought to light in this work. The author argues for an apparently obvious, but (...) relatively underexplored view of the classical hylomorphic concept of form, not just as the information that characterizes the organization of human body, but also as the intrinsic final reason why, through a specific type of bodily structure, the human being develops his/her natural inclinations and behaves according to them. The author advances the argument in terms of an upward comparison between the threefold levels of Thomas Aquinas’ natural human inclinations according to Summa Theologiae I-II, question 94, article 2, and the pioneering structural and functional “Triune Brain” model developed from 1949 to 1952 by Paul MacLean. The hylomorphic view sketched is profoundly different from a purely materialistic conception of teleological processes of human behavior, and it is a plausible explanation that motivates and invites further considerations and research.

Hans Jonas’ “philosophical biology,” although developed several decades ago, is still fundamental to the contemporary reflection upon the meaning of life in a systems thinking perspective. Jonas, in fact, closely examines the reasons of modern science, and especially of Wiener’s Cybernetics and Bertalanffy’s General System Theory, and at the same time points out their basic limits, such as their having a reductionistic attitude to knowledge and ontology. In particular, the philosopher highlights the problematic consequences of scientific reductionism for human nature. (...) As the final result of an overall process of naturalization, the essence of the human being is reduced to its quantitative features only, while the “meaning” of life as such becomes no different from the “fact” of its material consistency. However, the problem is that by such a process, the human being is deprived of his specificity. (shrink)

Neste trabalho, avaliamos as implicações que o debate filosófico acerca das explicações em termos de função e objetivo podem ter no contexto educacional, particularmente no ensino e aprendizagem de biologia. Para alcançar este objetivo, investigamos como três obras didáticas de biologia do Brasil utilizam a linguagem teleológica na formulação de explicações para os assuntos que são objeto de estudo dessa ciência. Na análise das obras, exploramos os enunciados teleológicos e funcionais a partir de dois projetos explanatórios discutidos na filosofia da (...) biologia contemporânea, a saber: (i) etiológico, que fornece uma abordagem essencialmente histórica de explicação biológica; e (ii) organizacional, que orienta o estudo acerca das capacidades de sistemas complexos mediante o apelo às funções de seus componentes, ou seja, a contribuição das partes para a realização de uma capacidade global. Nossos resultados mostram que poucas explicações podem ser qualificadas como etiológicas, em razão de que os autores preterem a discussão de temas segundo um tratamento evolutivo. Associado a esse resultado, a maioria dos enunciados foi localizada no contexto do projeto organizacional de explicação científica. Na análise das explicações, destacamos os principais problemas que elas apresentam, como a falta de clareza na identificação do explanandum e explanans, situação que pode prejudicar a compreensão dos assuntos pelos estudantes. Por fim, colocamos que a recontextualização das duas abordagens centrais sobre as explicações funcionais na filosofia da biologia, a perspectiva etiológica e a organizacional, podem fornecer um embasamento epistemológico consistente para as explicações biológicas no ensino médio.

The text of Physics 2.8 has been recently interpreted so as to restore the reading that Aristotle holds an external, and even an anthropocentric, natural teleology. This reading has been defended by D. Furley, and especially by D. Sedley. In this paper I present several arguments against this interpretation of the text. Thus, I will argue that Aristotle does not claim, in this chapter, that it rains for the sake of the growing of the crop, against an opinion which is (...) currently somewhat extended among interpreters.
