Individuals of many animal species are said to have a personality. It has been shown that some individuals are bolder than other individuals of the same species, or more sociable or more aggressive. In this paper, we analyse what it means to say that an animal has a personality. We clarify what an animal personality is, that is, its ontology, and how different personality concepts relate to each other, and we examine how personality traits are identified in biological practice. Our (...) analysis shows that biologists often study specific personality traits, such as boldness, sociability or aggressiveness, rather than personalities in general. We claim that personality traits are best understood as dispositions and that they are operationally defined in terms of certain sets of behaviours, which are studied in specific experimental set-ups. Furthermore, we develop an integrative philosophical account that specifies and formalises three criteria for identifying personality traits, which are used in biological practice. For an individual animal to have a personality trait it must, first, behave differently than others. Second, these behavioural differences must be stable over a certain time, and third, they must be consistent in different contexts. (shrink)

In recent years, philosophers have looked to empirical findings about psychopaths to help determine whether moral agency is underwritten by reason, or by some affective capacity, such as empathy. Since one of psychopaths’ most glaring deficits is a lack of empathy, and they are widely considered to be amoral, psychopaths are often taken as a test case for the hypothesis that empathy is necessary for moral agency. However, people with autism also lack empathy, so it is reasonable to think that (...) any empirically-informed attempt to answer the question of whether empathy is necessary for moral agency should give due attention to autism as well as psychopathy. Jeanette Kennett’s thought-provoking paper ‘Autism, Empathy and Moral Agency’ (2002) is an early and arguably the most notable example of such an attempt. Kennett argues that although autistic people and psychopaths both lack empathy, autistic people possess a ‘reverence for reason’ that enables them to become capable moral agents. By contrast, psychopaths lack this rational capacity, and it is this defect of reason rather than an empathic impairment that explains why they are amoral. Kennett thus concludes that empathy is not necessary for moral agency. In this chapter, I challenge Kennett’s argument. First, I review the empirical evidence in order to demonstrate that there is a component of empathy called affective empathy that is impaired in psychopaths but largely preserved in autistics. As such, the claim that psychopaths and autistics share a common lack of empathy is unjustified. Second, I challenge Kennett’s claim that empathy plays no role in explaining the moral difference between psychopaths and autistics. Instead, I contend that the intact affective empathy of autistic people is a crucial component of their capacity to act from reverence for reason. (shrink)

The current global COVID-19 pandemic has led to a deep and multidimensional crisis across all sectors of society. As countries contemplate their mobility and social-distancing policy restrictions, we have a unique opportunity to re-imagine the deliberative frameworks and value priorities in our food systems. Pre-pandemic food systems at global, national, regional and local scales already needed revision to chart a common vision for sustainable and ethical food futures. Re-orientation is also needed by the relevant sciences, traditionally siloed in their disciplines (...) and without adequate attention paid to how the food system problem is variously framed by diverse stakeholders according to their values. From the transdisciplinary perspective of food ethics, we argue that a post-pandemic scheme focused on bottom-up, regional, cross-sectoral and non-partisan deliberation may provide the re-orientation and benchmarks needed for not only more sustainable, but also more ethical food futures.

This paper analyzes what it means for philosophy of science to be normative. It argues that normativity is a multifaceted phenomenon rather than a general feature that a philosophical theory either has or lacks. It analyzes the normativity of philosophy of science by articulating three ways in which a philosophical theory can be normative. Methodological normativity arises from normative assumptions that philosophers make when they select, interpret, evaluate, and mutually adjust relevant empirical information, on which they base their philosophical theories. (...) Object normativity emerges from the fact that the object of philosophical theorizing can itself be normative, such as when philosophers discuss epistemic norms in science. Metanormativity arises from the kind of claims that a philosophical theory contains, such as normative claims about science as it should be. Distinguishing these three kinds of normativity gives rise to a nuanced and illuminating view of how philosophy of science can be normative. (shrink)

In the contemporary life sciences more and more researchers emphasize the “limits of reductionism” (e.g. Ahn et al. 2006a, 709; Mazzocchi 2008, 10) or they call for a move “beyond reductionism” (Gallagher/Appenzeller 1999, 79). However, it is far from clear what exactly they argue for and what the envisioned limits of reductionism are. In this paper I claim that the current discussions about reductionism in the life sciences, which focus on methodological and explanatory issues, leave the concepts of a reductive (...) method and a reductive explanation too unspecified. In order to fill this gap and to clarify what the limits of reductionism are I identify three reductive methods that are crucial in the current practice of the life sciences: decomposition, focusing on internal factors, and studying parts in isolation. Furthermore, I argue that reductive explanations in the life sciences exhibit three characteristics: first, they refer only to factors at a lower level than the phenomenon at issue, second, they focus on internal factors and thus ignore or simplify the environment of a system, and, third, they cite only the parts of a system in isolation.

The central aim of this article is to specify the ontological nature of constitutive mechanistic phenomena. After identifying three criteria of adequacy that any plausible approach to constitutive mechanistic phenomena must satisfy, we present four different suggestions, found in the mechanistic literature, of what mechanistic phenomena might be. We argue that none of these suggestions meets the criteria of adequacy. According to our analysis, constitutive mechanistic phenomena are best understood as what we will call ‘object-involving occurrents’. Furthermore, on the basis (...) of this notion, we will clarify what distinguishes constitutive mechanistic explanations from etiological ones. 1 Introduction 2 Criteria of Adequacy 2.1 Descriptive adequacy 2.2 Constitutive–etiological distinction 2.3 Constitution 3 The Ontological Nature of Constitutive Mechanistic Phenomena 3.1 Phenomena as input–output relations 3.2 Phenomena as end states 3.3 Phenomena as dispositions 3.4 Phenomena as behaviours 4 Phenomena as Object-Involving Occurrents 4.1 What object-involving occurrents are and why we need them 4.2 The object in the phenomenon 4.3 The adequacy of option 5 Conclusion.

In this paper I argue that it is finally time to move beyond the Nagelian framework and to break new ground in thinking about epistemic reduction in biology. I will do so, not by simply repeating all the old objections that have been raised against Ernest Nagel’s classical model of theory reduction. Rather, I grant that a proponent of Nagel’s approach can handle several of these problems but that, nevertheless, Nagel’s general way of thinking about epistemic reduction in terms of (...) theories and their logical relations is entirely inadequate with respect to what is going on in actual biological research practice.

In A Better Ape, Victor Kumar and Richmond Campbell (2022) provide an ambitious and compelling history of the evolution of human morality. Informed by evidence from an impressively vast multidisciplinary literature, they offer a rich bio-cultural evolutionary explanation of how the human moral mind arose and developed over time that has wide appeal for philosophers and scientists alike. In this paper, I examine Kumar and Campbell’s novel moral psychology and raise questions about their account of the relationship between moral norms (...) and core moral emotions. I also argue that social essentialist cognition has a place alongside the moral emotions as a key ingredient in Kumar and Campbell’s view of the moral mind as well as in their normative account of how to work towards moral progress.

Argument-mapping software abounds, and one of the reasons is that using the software has been shown to teach/promote/improve critical thinking skills. These positive results are very encouraging, but they also raise the question of whether the computer tutorial environment is producing these results, or whether learning argument mapping, even with just paper and pencil, is sufficient. Based on the results of two empirical studies, I argue that the basic skill of being able to represent an argument diagrammatically plays an important (...) role in the improvement of critical-thinking skills. While these studies do not offer a direct comparison between the two methods, it is important for anyone wishing to employ argument mapping in the classroom to know that significant results can be obtained even with the most rudimentary of tools.

Problem-Based Learning has become an increasingly popular instructional method for a variety of disciplines at all levels. Many studies and meta-analyses of these studies have shown the efficacy of this method for developing knowledge and skills. I adopted this method for teaching Engineering Ethics at Carnegie Mellon University, which has as its main course objectives the development of moral reasoning skills, as well as collaboration and communication skills, with special attention given to ethical dilemmas that may arise in the normal (...) course of an engineer’s professional career. In the most recent iteration of the course, I used the Engineering and Science Issues Test as a pretest and posttest to test the development of my students’ moral reasoning skills over the course of the semester. Based on the results of these tests, I argue that the students in my Engineering Ethics course did in fact significantly develop their moral reasoning skills. (shrink)

In this paper, I defend a novel skeptical view about moral disgust. I argue that much recent discussion of moral disgust neglects an important ontological question: is there a distinctive psychological state of moral disgust that is differentiable from generic disgust, and from other psychological states? I investigate the ontological question and propose two conditions that any aspiring account of moral disgust must satisfy: it must be a genuine form of disgust, and it must be genuinely moral. Next, I examine (...) two prominent accounts of moral disgust by John Kekes and Victor Kumar and argue that neither successfully establishes the existence of genuinely moral disgust: Kekes’ account does not satisfy the second condition, and Kumar’s view does not meet the first. I claim that an important general lesson can be drawn from my critiques of Kekes’ and Kumar’s accounts: to establish the existence of moral disgust, one must provide unequivocal evidence that genuinely moral disgust, not generic disgust or anger, is being elicited in response to relevant moral violations. I conclude by considering why we ought to be skeptical about the general prospect of giving a positive answer to the ontological question, given the available evidence. (shrink)

Leuridan (2011) questions whether mechanisms can really replace laws at the heart of our thinking about science. In doing so, he enters a long-standing discussion about the relationship between the mech-anistic structures evident in the theories of contemporary biology and the laws of nature privileged especially in traditional empiricist traditions of the philosophy of science (see e.g. Wimsatt 1974; Bechtel and Abrahamsen 2005; Bogen 2005; Darden 2006; Glennan 1996; MDC 2000; Schaffner 1993; Tabery 2003; Weber 2005). In our view, Leuridan (...) misconstrues this discussion. His weak positive claim that mechanistic sciences appeal to generalizations is true but uninteresting. His stronger claim, that all causal claims require laws, is unsupported by his arguments. Though we proceed by criticizing Leuridan’s arguments, our greater purpose is to embellish his arguments in order to show how thinking about mechanisms enriches and transforms old philosophical debates about laws in biology and provides new insights into how generalizations afford prediction, explanation and control.

Mechanisms are said to consist of two kinds of components, entities and activities. In the first half of this chapter, I examine what entities and activities are, how they relate to well-known ontological categories, such as processes or dispositions, and how entities and activities relate to each other (e.g., can one be reduced to the other or are they mutually dependent?). The second part of this chapter analyzes different criteria for individuating the components of mechanisms and discusses how real the (...) boundaries of mechanisms are. (shrink)

This paper examines the adequacy of causal graph theory as a tool for modeling biological phenomena and formalizing biological explanations. I point out that the causal graph approach reaches it limits when it comes to modeling biological phenomena that involve complex spatial and structural relations. Using a case study from molecular biology, DNA-binding and -recognition of proteins, I argue that causal graph models fail to adequately represent and explain causal phenomena in this field. The inadequacy of these models is due (...) to their failure to include relevant spatial and structural information in a way that does not render the model non-explanatory, unmanageable, or inconsistent with basic assumptions of causal graph theory.

This paper examines various ways in which philosophy of science can be interdisciplinary. It aims to provide a map of relations between philosophy and sciences, some of which are interdisciplinary. Such a map should also inform discussions concerning the question “How much philosophy is there in the philosophy of science?” In Sect. 1, we distinguish between synoptic and collaborative interdisciplinarity. With respect to the latter, we furthermore distinguish between two kinds of reflective forms of collaborative interdisciplinarity. We also briefly explicate (...) how complexity triggers interdisciplinarity. In Sect. 2, we apply the distinctions of Sect. 1 to philosophy of science and analyze in which sense different styles of philosophy of science are interdisciplinary. The styles that we discuss are a synoptic-general, a reflective-general, a reflective-particular, a particular-embedded and a descriptive or normative style. (shrink)

What are the conditions under which one biological object is a part of another biological object? This paper answers this question by developing a general, systematic account of biological parthood. I specify two criteria for biological parthood. Substantial Spatial Inclusionrequires biological parts to be spatially located inside or in the region that the natural boundary of t he biological whole occupies. Compositional Relevance captures the fact that a biological part engages in a biological process that must make a necessary contribution (...) to a condition that is minimally sufficient to one or more of the characteristic behaviors of the biological whole. Instead of emphasizing the diversity of part-whole relations in the biological world, this paper asks what biological part-whole relations have in common and what constrains their existence, in general. After presenting the two criteria for biological parthood I discuss in how far my account can cope with hard cases (e.g., redundant parts) and I reveal the merits and limits of monism. (shrink)

Das Thema des Artikels sind sprachliche Fehler, die bei der schriftlichen Übersetzung aus dem Deutschen ins Polnische und aus dem Polnischen ins Deutsche Vorkommen. Das Ziel des Artikels ist, ihre Vielschichtigkeit und Entstehungsmechanismen zu zeigen, die vor allem mit der sprachlichen Interferenz als einer der Hauptursachen für Übersetzungsfehler zusammenhän gen. Der Artikel stützt sich auf die Ergebnisse der Untersuchungen, die in den Jahren 2004-2006 in der Abteilung für Angewandte Sprachwissenschaft am Lehrstuhl für Deutsche und Angewandte Sprachwissenschaft der Universität Łódź durchgeführt (...) wurden. Die Basis für das empirische Material bildeten hierbei durch Germanislikstudenten angefertigte schriftliche Übersetzungen. Am Anfang des Artikels werden verschiedene Definitionen und Klassifizierungsmöglichkeiten des sprachlichen Fehlers präsentiert. Desweiteren konzentriert sich der Autor auf das Phänomen der sprachlichen Interferenz und führt ihre Definitionen von W. Bondzio und T. Lewandowski an. Im weiteren Teil des Artikels wird die Frage der Interferenzmechanismen erörtert, zu denen die von J. Czochralski beschriebene Automatisierung der sprachlichen Strukturen, „zwischensprachliche Zuordnung“, „Übertragung des muttersprachlichen Modells“, fehlerhafte Erweiterung des Geltungsbereiches einer Aussage oder die Vermeidung besiimmter Elemente im System der Fremdsprache gehören. Im zweiten Teil des Artikels werden Ergebnisse der Forschungen präsentiert, deren Korpus einige Hunderte von deutsch-polnischen und polnisch-deutschen Übersetzungen waren, die von Studenten gemacht wurden. Die Fehler wurden zunächst nach der Richtung der Interferenz klassifiziert, dann nach den Sprachebenen. Besondere Aufmerksamkeit bei der Fehlerbeschreibung wurde аиГ die möglichen Störungen der sprachlichen Kommunikation gelenkt. Die durchgeführten Untersuchungen untermauern und erweitern die Thesen aus der Fachliteratur: Die Fehler kommen auf verschiedenen Sprachebenen vor und stören in vielen Fällen die sprachliche Kommunikation, deren Herstellung der Hauptzweck einer jeden Übersetzung ist. Der Autor des Artikels postuliert, bei der Übersetzungsdidaktik mehr Aufmerksamkeit der sprachlichen Interferenz zu widmen, was seiner Meinung nach zu besseren Resultaten verhelfen würde. (shrink)

Biological individuality is a notoriously thorny topic for biologists and philosophers of biology. In this paper we argue that biological individuality presents multiple, interconnected questions for biologists and philosophers that together form a problem agenda. Using a case study of an interdisciplinary research group in ecology, behavioral and evolutionary biology, we claim that a debate on biological individuality that seeks to account for diverse practices in the biological sciences should be broadened to include and give prominence to questions about uniqueness (...) and temporality. We show that broadening the problem agenda of biological individuality draws attention to underrecognized philosophical issues and discussions and thereby organizes and enriches the existing debate.

Modeling mechanisms is central to the biological sciences – for purposes of explanation, prediction, extrapolation, and manipulation. A closer look at the philosophical literature reveals that mechanisms are predominantly modeled in a purely qualitative way. That is, mechanistic models are conceived of as representing how certain entities and activities are spatially and temporally organized so that they bring about the behavior of the mechanism in question. Although this adequately characterizes how mechanisms are represented in biology textbooks, contemporary biological research practice (...) shows the need for quantitative, probabilistic models of mechanisms, too. In this paper we argue that the formal framework of causal graph theory is well-suited to provide us with models of biological mechanisms that incorporate quantitative and probabilistic information. On the ba-sis of an example from contemporary biological practice, namely feedback regulation of fatty acid biosynthesis in Brassica napus, we show that causal graph theoretical models can account for feedback as well as for the multi-level character of mechanisms. However, we do not claim that causal graph theoretical representations of mechanisms are advantageous in all respects and should replace common qualitative models. Rather, we endorse the more balanced view that causal graph theoretical models of mechanisms are useful for some purposes, while being insufficient for others. (shrink)

In a companion article, “Terrible Knowledge And Tertiary Trauma, Part I: Japanese Nuclear Trauma And Resistance To The Atomic Bomb” (this issue), I argue that we need to teach about the atomic bombings of Hiroshima and Nagasaki, even though the material is difficult emotionally as well as intellectually. Because of the nature of the information, this topic can be as difficult for graduate students (and their professors!) as for younger students. Teaching about the atomic bombings, however, demands special treatment if (...) we are to prevent a sense of isolation, immobilization, or helplessness in students. We can do this by building a strong community of learning, offering students as much control over their learning as possible, and helping them find ways to connect to larger social and political processes and movements that make sense of an endangered world. Here I offer some thoughts on how to teach it, along with discussion questions, applicable to K-graduate school. Since middle-school students are becoming keenly aware of the larger world through the Internet, and middle school teaching can be (comparatively) easy to adapt for other age groups, I also offer some suggestions of some materials and projects appropriate for use with that age group.

This article discusses twelve reasons that we must teach about the 1945 American atomic bombings of Hiroshima and Nagasaki. As with Holocaust studies, we must teach this material even though it is both emotionally and intellectually difficult—in spite of our feelings of repugnance and/or grief, and our concerns regarding students’ potential distress (“tertiary trauma”). To handle such material effectively, we should keep in mind ten objectives: 1) to expand students' knowledge about the subject along with the victims’ experience of it; (...) 2) to develop teachers’ awareness of and comfort with it; 3) to help students cope with this knowledge so they are not traumatized themselves; 4) to make sure students don't take refuge in callousness, inappropriate humor, blaming the victim, or despair; 5) to enable students to teach others about the event(s); 6) to enable students to use their increased knowledge and self-reflection individually and as part of the national dialogue; 7) to deepen and “complexify” the conversation on the bombings; 8) to develop supports for teachers and students throughout this process;” 9) to reintegrate the objective with the subjective, recognizing that emotion may be appropriate to some learning; 10) to instigate a dialogue allowing teachers and students to continue to investigate this and related topics.

We propose four policies of ethical design of human-grade Artificial Intelligence. Two of our policies are precautionary. Given substantial uncertainty both about ethical theory and about the conditions under which AI would have conscious experiences, we should be cautious in our handling of cases where different moral theories or different theories of consciousness would produce very different ethical recommendations. Two of our policies concern respect and freedom. If we design AI that deserves moral consideration equivalent to that of human beings, (...) that AI should be designed with self-respect and with the freedom to explore values other than those we might impose. We are especially concerned about the temptation to create human-grade AI pre-installed with the desire to cheerfully sacrifice itself for its creators’ benefit. (shrink)

In this paper, we discuss some problems and prospects of interdisciplinary encounters by focusing on philosophy of science as a case study. After introducing the case, we give an overview about the various ways in which philosophy of science can be interdisciplinary in Section 2. In Section 3, we name some general problems concerning the possible points of interaction between philosophy of science and the sciences studied. In Section 4 we compare the advantages and risks of interdisciplinarity for individual researchers (...) and institutions. In Section 5, we discuss interdisciplinary PhD programs, in particular concerning two main problems: increased workload and the quality of supervision. In the final Section 6, we look at interdisciplinary careers beyond the PhD. (shrink)

Convincing disputes about explanatory reductionism in the philosophy of biology require a clear and precise understanding of what a reductive explanation in biology is. The central aim of this book is to provide such an account by revealing the features that determine the reductive character of a biological explanation. Chapters I-IV provide the ground, on which I can then, in Chapter V, develop my own account of explanatory reduction in biology: Chapter I reveals the meta-philosophical assumptions that underlie my analysis (...) of reduction, Chapter II introduces the previous debate about reduction in the philosophy of biology by pointing out the most crucial lessons one should learn from this debate, Chapter III critically discusses the two perspectives on explanatory reduction that have been proposed in the philosophy of biology so far, and Chapter IV clarifies in what ways the issue of reduction is entangled with the issue of explanation. In Chapter V I present my own account of explanatory reduction. My main claim is that reductive explanations in the biological sciences possess three main characteristics: they explain the behavior of a biological system S, first, exclusively in terms of factors that are located on a lower level of organization than S, second, by focusing on factors that are internal to S , and third, by describing the genuine parts of S only as “parts in isolation”. This account is ontic because it traces the reductivity of an explanation back to certain relations that exist in the world. (shrink)

Charles Darwin hat eindrucksvoll gezeigt, dass der Mensch ebenso wie alle anderen Lebewesen ein Produkt der biologischen Evolution ist. Die sich an Darwin anschließende Forschung hat außerdem plausibel gemacht, dass sich nicht nur viele der körperlichen Merkmale des Menschen, sondern auch (zumindest einige) seiner Verhaltensdispositionen in adaptiven Selektionsprozessen herausgebildet haben. Die Vorstellung, dass auch die menschliche Moralität evolutionär bedingt ist, scheint daher auf den ersten Blick ganz überzeugend. Schließlich hat die Evolutionstheorie in den vergangenen Jahrzehnten in vielen Bereichen (auch außerhalb (...) der Biologie) ihre weitreichende Bedeutung unter Beweis gestellt. Warum sollte, so könnte man beispielsweise fragen, gerade die Fähigkeit des Menschen, moralische Normen aufzustellen und gemäß ihnen zu handeln, nicht evolutionär erklärt werden können? Und warum sollte eine solche evolutionäre Erklärung der menschlichen Moralität irrelevant für die Rechtfertigung moralischer Normen sein? Warum sollte die Ethik eine Bastion der Philosophen bleiben, für die evolutionsbiologische Forschungsergebnisse über den Menschen und seine nächsten Verwandten keinerlei Relevanz besitzen? (shrink)

Le modèle unificationniste de l’explication métaphysique, basé sur les travaux de Kitcher sur l’explication scientifique, offre une alternative intéressante aux modèles présumant la conception supportive de l’explication métaphysique [backing model]. Par contre, le caractère adéquat de ce modèle, i.e. sa capacité à classifier comme métaphysiquement explicative/non-explicative des propositions qui préthéoriquement sont classés comme tel, n’a pas encore été exploré. Pour ce faire, des interprétations pour les relations de détermination et d’appartenance à un ensemble sont fournies. Celles-ci étant potentiellement sujette au (...) problème d’artificialité, i.e. présence d’un biais structurel favorisant l’attribution du caractère explicatif, une réponse est offerte. En effet, le modèle unificationniste permet d’identifier les patrons argumentatifs pouvant être légitimement mis en compétition en comparant la distance entre les ensembles de faits qui doivent être considérés comme vrais dans la formulation d’un patron argumentatif. Cette propriété a des conséquences intéressantes dans l’identification du niveau adéquat de débat entre des propositions compétitrices. (shrink)

Le problème de l’induction (humien) a récemment été abordé par Steel dans son article de 2010. Celui-ci soutient que les théories d’apprentissage formelles permettent de justifier logiquement le principe de l’induction, ce dernier assurant la fiabilité logique des méthodes. Cette proposition a été critiquée par Howson en 2011, ce dernier mettant en doute la possibilité même qu’une méthode puisse être logiquement fiable. Bien que Steel ait offert une réponse à cette critique, il n’y répond pas directement. Dans le présent article, (...) une réponse frontale à celle-ci est offerte en s’inspirant des pratiques de tests d’hypothèses en sciences biologiques. Pour ce faire, une règle de construction des ensembles d’hypothèses est proposée, règle offrant une justification logique au fait qu’une méthode convergera nécessairement vers la vérité. Cet amendement étant cohérent avec l’ensemble de la proposition de Steel, il est ainsi possible d’affirmer que sa thèse est renforcée par cette proposition. (shrink)

'Chance' is defined as an event on the time scale withour any cause before it appears. That means, that cause and effect is identical. This is the only way to integrate chance into a consistent theory of causality. The identity of cause and effect is called AHK theorem (Aristotle-Hegel-Kaiser).

In this article, we reconsider the syntactical analysis as well as the categorial status of two Medieval French elements, et and ne. In this connection, we illustrate and compare various approaches which principally differ with regard to the assignment of a unique category or of various categories to these elements. In the context of this comparison, we address some of the questions pertaining to their motivations and the evidence which has been offered in their favor, showing that approaches which assign (...) a unique category to et and ne, respectively, prove to be empirically more adequate.
