This article presents a reading of Carl Schmitt’s Concept of the Political, in recourse to lesser known works of his such as Dictatorship and On the Three Types of Juristic Thought and in light of a hypothesis developed while examining his comment to Concept, going back to the German re-edition of the latter in 1963. There, Schmitt offers an interpretative scheme he has himself named “Hobbes-Crystal”, encapsulating not only a suggestion of how to decipher Hobbes, but also Schmitt’s own approach (...) to politics as Political Theology. As I argue below, the relevant comment also hints at Schmitt’s opposing stance to Natural Law as a legal paradigm and philosophical tradition. I show how this is supported by the Concept’s main text and other works mentioned above, proceeding to claim the former functions on a double-level: Schmitt‘s nominalist inquiry in the concept, circular in itself (although favourably supported by a sup-posedly mere description of what is “the case”) sits on premises which not only have not been articulated openly, but also contradict the nominalist proceeding. Bringing both insights to-gether and fleshing them out by close reading, I show that Schmitt’s nominalism presupposes his adversary stance towards Natural Law. Examining the arguments for this position of his and endorsing Oliver Marchart’s work in history of political theory, I read the nominalist façade of the Concept as a case of postfundamentalist criticism of Natural Law, which Schmitt’s Hobbes studies were formative to.

Haeusermann et al. (Citation2023) draw three overall conclusions from their study on closed loop neuromodulation and self-perception in clinical treatment of refractory epilepsy. The first is that closed-loop neuromodulation devices did not substantially change epileptic patient’s personalities or self-perception postoperatively. The second is that some patients and caregivers attributed observed changes in personality and self-perception to the epilepsy itself and not to the DBS treatments. The third is that the devices provided participants with novel ways to make sense of their (...) illness. These findings further demonstrate a misalignment between some neuroethicists’ concerns about putative postoperative changes to personality, and the empirical evidence for such changes. Haeusermann et al. nonetheless concede that “neurotechnology directed at persisting rather than episodic clinical phenomena could have greater implications for personality or self-perception, either because they operate more continuously or are directed at clinical phenomena that are more stably integrated into patients’ self-concepts” (41). We acknowledge that the hypothesis that participants did not report changes because they were only episodically and not continually stimulated offers an interesting line for future investigation. Nonetheless, we would like to propose that potential postoperative personality changes might be correlated with the pathophysiology itself, rather than the stimulation effects of the technology. Generally, we advance the view that unintended effects solely induced by the technology cannot be excluded per se. Regardless, this comment aims to highlight that ethicists’ starting premise should be that patients suffering from diverse pathophysiology, or patients who are treated with stimulation in different brain regions and with differing parameters, would likely not react in the same way to treatment.

. Computational chemistry grew in a new era of “desktop modeling,” which coincided with a growing demand for modeling software, especially from the pharmaceutical industry. Parameterization of models in computational chemistry is an arduous enterprise, and we argue that this activity leads, in this specific context, to tensions among scientists regarding the epistemic opacity transparency of parameterized methods and the software implementing them. We relate one flame war from the Computational Chemistry mailing List in order to assess in detail the (...) relationships between modeling methods, parameterization, software and the various forms of their enclosure or disclosure. Our claim is that parameterization issues are an important and often neglected source of epistemic opacity and that this opacity is entangled in methods and software alike. Models and software must be addressed together to understand the epistemological tensions at stake. (shrink)

In this article, I argue that by considering Ludwig Wittgenstein's methods, we can better understand and appreciate Jonas Mekas's diary films. Based on Wittgenstein's notion of “aesthetic puzzlement”, I identify the main confusions encountered by the viewer upon watching Mekas's films, such as: 1) fragmentation; 2) persistent repetition; and 3) the importance placed on the everyday. I discuss three films – Walden (1969), Lost Lost Lost (1976), and As I Was Moving Ahead Occasionally I Saw Brief Glimpses of Beauty (2000) (...) – and demonstrate that the aesthetic puzzlements within them may be dissolved by looking at the format of Wittgenstein's Philosophical Investigations (1953). Mekas's lifelong interest in filming the most mundane and domestic scenes can be understood as a puzzlement in itself: why not just admire the ordinary whilst living in it? Wittgenstein's thought experiment in Culture and Value helps us understand the aesthetic puzzlement of Mekas's interest in filming, remembering and presenting an extensive array of everyday activities, and also explains why the viewer can find the most mundane and domestic activities in his films remarkable. Additionally, I discuss how Mekas's diary films may be regarded as coming close to Wittgenstein's aesthetic ideal of art as being able to represent “life itself”. I aim to show how Mekas's cinematic practice places extreme importance on ordinary acts and offers a mode of thinking which echoes Wittgenstein's own views on philosophy. I conclude with a discussion of “nomadism”, a notion that elucidates the peculiar form of the works of both Wittgenstein and Mekas. (shrink)

The article focuses on the narratives of women secretaries regarding their work experiences in private business in Latvia, and aims at understanding the barriers that prevent the formation of women’s political subjectivity in Latvia, by looking at why sexual harassment does not become a political issue for working women in Latvia. Using Hayden White’s theory of trope analysis, the article analyses the dominant tropes and the political results of their use in secretaries’ articulations and narratives about their experiences of sexual (...) harassment. Additionally, the article provides a critical trope analysis of Western feminist theories of sexual harassment, thus pointing out their usefulness for women’s politics in Latvia. Finally, the article outlines the discursive strategies that women in Latvia could use in order to claim their own distinct and transformative political subjectivity in the newly independent, capitalist and highly nationalist post-Soviet Latvia.

This book is a unique introductory overview of decision theory. It is completely non-technical, without a single formula in the book. Written in a crisp and clear style it succinctly covers the full range of philosophical issues of rationality and decision theory, including game theory, social choice theory, prisoner's dilemma and much else. The book aims to expand the scope and enrich the foundations of decision theory. By addressing such issues as ambivalence, inner conflict, and the constraints imposed upon us (...) by our attachments to others, Frederic Schick reveals that our thinking is often more subtle than standard theories of rationality allow. Only a theory that respects that subtlety can illumine what is otherwise puzzling. The book contains many examples drawn from history and literature dealing with subjects such as love, war, friendship, and crime. (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.

Before the Darwinian revolution species were thought to be universals. Since then, numerous attempts have been made to propose new definitions. The twentieth-century German philosopher Nicolai Hartmann defined 'species' as an individual system of processes and a process of life of a higher-order. To provide a clear understanding of Hartmann's conception of species, I first present his method of definition. Then I look at Hartmann's Philosophie der Natur (1950) to present his concepts of "organism" and "species." And I end the (...) paper by pointing out two possible systematic inconsistencies.

Considering world problems in a context of inter human relationship, I refer to the approach developed in Emmanuel Levinas' ethics. This approach encourages raising a question about the potential usefulness of knowledge in solving problems of human relationship. The fundamental trait of the human condition face-toface with the other is, according to Levinas, unrestricted responsibility of the I about the other. The other has ethical, not ontological, authority, which explains why observable deafness to one's responsibility can not serve as a (...) proof against its absolute nature. Consequently, whatever one's judgement on the current situation, moral requirements are valid. The relationship between the I and the other comes before any theory and there is no need for the help of knowledge. However, the multiplicity of human beings demands a solution to problems involving many people. There arises a need for theoretical thought—its aim is to pose a question of justice. Ethical knowledge for Levinas is primary. Ethically motivated thought can seek knowledge as received from the other. Such knowledge can help to conceive of just action, if there is a wish to perform it. But it is not knowledge that motivates one to act morally and it is not argument that can convince one to act this way. (shrink)

My starting point in the exploration of the two subjects’ dialectics would be something what is perceived by Luce Irigaray, namely, that the humane nature is two, but the two is not represented in the philosophical discourse and the woman has always been symbolised as the other or lack. In Irigaray philosophy the crucial otherness is the other belonging to the other gender. The dialectical process now is in the service of intersubjectivity. Luce Irigaray argues that the recognition of the (...) other as sexuate other offers the possibility to overcome the master – slave dialectics, because between woman and man, man and woman, recognitionrequires the labour of the negative. Irigaray sees in the recognition process the moment of acceptance of one’s own limits and of the limits of the other. Renouncement of the opposition activity / passivity is crucial for Luce Irigaray concept of the two subject’s dialectics. Luce Irigaray’s contribution to the contemporary discussions of the role of passivity and activity in subject’s relationship to the other (Paul Ricoeur, Jacques Derrida, Emmanuel Levinas) is crucial.

Brief, accessible, and affordable, these pocket-sized volumes offer the essential introductions to the great philosophers of the Western tradition-from Plato to Wittgenstein.

The Russian philosopher Nikolai Onufrievich Lossky adhered to an evolutionary metaphysics of reincarnation according to which the world is constituted of immortal souls or monads, which he calls ‘substantival agents.’ These substantival agents can evolve or devolve depending on the goodness or badness of their behavior. Such evolution requires the possibility for monads to reincarnate into the bodies of creatures of a higher or of a lower level on the scala perfectionis. According to this theory, a substantival agent can evolve (...) by being gradually reincarnated multiple times through a sort of process of metamorphosis from the level of the most elementary particles all the way up to the level of human beings or even higher. In ‘Ученiе Лейбница о перевоплощенiи какъ метаморфозѣ’, Lossky argues that the works of Leibniz contain scattered elements of such a systematic evolutionary doctrine of reincarnation as metamorphosis and he attempts to reconstitute this doctrine. The present article is intended as an historical introduction to the translation of Lossky’s ‘Leibniz’s Doctrine of Reincarnation as Metamorphosis.’. (shrink)

Philosophy is one of the most intimidating and difficult of disciplines, as any of its students can attest. This book is an important entry in a distinctive new series from Routledge: The Great Philosophers . Breaking down obstacles to understanding the ideas of history's greatest thinkers, these brief, accessible, and affordable volumes offer essential introductions to the great philosophers of the Western tradition from Plato to Wittgenstein. In just 64 pages, each author, a specialist on his subject, places the philosopher (...) and his ideas into historical perspective. Each volume explains, in simple terms, the basic concepts, enriching the narrative through the effective use of biographical detail. And instead of attempting to explain the philosopher's entire intellectual history, which can be daunting, this series takes one central theme in each philosopher's work, using it to unfold the philosopher's thoughts.

This book is a guide to working with social science concepts. Concepts are the prisms through which we see the social world. They are foundational to the social science enterprise, and the quality of investigations hinges in part on how well researchers make use of them. Most social science concepts are drawn from ordinary language used in everyday ways; however, many social scientists "reconfigure" ordinary words to meet their research needs. They tinker with the meanings of words to fit their (...) theoretical aims and make them precise, useful tools of measurement and comparison. This book examines social science concepts through an interpretivist lens with the aim of providing concrete conceptual guidance for future research. Specifically, this book seeks to: 1) identify characteristic dangers that attend the making and use of reconfigured concepts; 2) lay out ways in which a select number of interpretivist approaches have been used to mitigate these dangers; 3) introduce practical tools that rework these interpretivist approaches into explicit and useable research methods; 4) show concretely how these elucidation tools can be gainfully used by social scientists working both within and outside of the interpretivist tradition. It will be an essential guide for social science research. (shrink)

What are the motivational bases that help explain the various normative judgements that social agents make, and the normative reasoning they employ? Answering this question leads us to consider the relationships between thoughts and emotions. Emotions will be described as thought-dependent and thought-directing, and as being intimately related to normativity. They are conceived as the grounds that motivate social agents to articulate their reasoning with respect to the values and norms they face and/or share in their social collective. It is (...) argued that because they are modes of thinking, emotions generate cognitive activities that relate to the making of evaluative and deontic judgements, the utterance of speech acts, the mastering of normative concepts and the building of arguments. Furthermore, each type of emotion generates its own constitutive judgements and structures normative thinking according to its own logic. The main thesis is that emotions provide sociological explanations for social agents’ thinking and speech, for emotions are precisely what motivate and, especially, structure normative reasoning and language. Being observable in language, emotions allow us to explain a) how social subjects reason and argue through norms and values, and b) how social subjects through their speech acts can contribute to the (un-)making of the social world.

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.

Intentional explanation, according to Elster, seeks to elucidate an action by showing that it was intentionally conducted, in order to bring about certain goals . Intentional actions furthermore, are rational actions: they imply that agents establish a connection between the goals they target and the means that are appropriate to reach them, by way of different beliefs about the means, the goals and the environment. But how should we understand intentional actions in the light of philosophical research on emotions, rationality, (...) and normativity? This question is the departure point of this article. Various philosophers have analyzed the relationships between rationality and emotion, those between emotion and normativity, and those between emotion and intentional action. Nonetheless, their theses are scattered and do not offer an integrative view on how rationality, normativity and emotions work from the standpoint of intentional explanation. By using de Sousa’s distinction between the epistemic and the strategic modes of rationality as a theoretical framework, this article proposes therefore to remedy this deficit by unifying these philosophical insights with the goal of elaborating a theory of intentional explanation which brings together rationality, normativity and emotions.

When developing phylogenetic systematics, the entomologist Willi Hennig adopted elements from Nicolai Hartmann’s ontology. In this historical essay I take on the task of documenting this adoption. I argue that in order to build a metaphysical foundation for phylogenetic systematics, Hennig adopted from Hartmann four main metaphysical theses. These are (1) that what is real is what is temporal; (2) that the criterion of individuality is to have duration; (3) that species are supra-individuals; and (4) that there are levels of (...) reality, each of which may be subject to different kinds of law. Reliance on Hartmann’s metaphysics allowed Hennig to ground some of the main theoretical principles of phylogenetic systematics, namely that the biological categories—from the semaphoront to the highest rank—have reality and individuality despite not being universals, and that they form a hierarchy of levels, each of which may require different kinds of explanation. Hartmann’s metaphysics thereby provided a philosophical justification for Hennig’s phylogenetic systematics, both as a theory and as a method of classification. (shrink)

The idea that deep brain stimulation (DBS) induces changes to personality, identity, agency, authenticity, autonomy and self (PIAAAS) is so deeply entrenched within neuroethics discourses that it has become an unchallenged narrative. In this article, we critically assess evidence about putative effects of DBS on PIAAAS. We conducted a literature review of more than 1535 articles to investigate the prevalence of scientific evidence regarding these potential DBS-induced changes. While we observed an increase in the number of publications in theoretical neuroethics (...) that mention putative DBS-induced changes to patients’ postoperative PIAAAS, we found a critical lack of primary empirical studies corroborating these claims. Our findings strongly suggest that the theoretical neuroethics debate on putative effects of DBS relies on very limited empirical evidence and is, instead, reliant on unsubstantiated speculative assumptions probablyin lieuof robust evidence. As such, this may reflect the likelihood of a speculative neuroethics bubble that may need to be deflated. Nevertheless, despite the low number of first-hand primary studies and large number of marginal and single case reports, potential postoperative DBS changes experienced by patients remain a critical ethical concern. We recommend further empirical research in order to enhance theoretical neuroethics work in the area. In particular, we call for the development of better instruments capable of capturing potential postoperative variations of PIAAAS. (shrink)

The bergsonian Conception of Time AbstractThe aim of this article is to show how Bergson´s philosophy derives from the understanding of the passing of time as an original and primordial fact. In this way, his works can be considered to be different attempts to explain this experience of temporality which, philosophically considered, consist of the intuition of duration. Thus, we examine the way in which the treatment given to distinct philosophical problems discussed in each of his works takes place as a meditation on the primitive fact and its progressive clarification. Firstly, we follow the course of deduction of the main characteristics of duration, succession, conservation and act, emphasizing some of his philosophical consequences. We then examine the critical dimension of Bergson´s philosophy through the analysis of the thought of the instant, which distorts the experience of time and gives rise to an equivocal way of traditional metaphysics; in this examination we shall seek to differentiate this idea from the experience of simultaneity that constitutes our concrete relationship with things.Duration.

The phenomenological effects of deep brain stimulation (DBS) on the self of the patient remains poorly understood and under described in the literature, despite growing evidence that a significant number of patients experience postoperative neuropsychiatric changes. To address this lack of phenomenological evidence, we conducted in-depth, semistructured interviews with 17 patients with Parkinson's disease who had undergone DBS. Exploring the subjective character specific to patients' experience of being implanted gives empirical and conceptual understanding of the potential phenomenon of DBS-induced self-estrangement. (...) Our study concluded that (1) the more patients preoperatively felt alienated by their illness, the more they experienced postoperative self-estrangement, and (2) the notion of self-estrangement seems to exist in association with certain common qualitative characters, namely, loss of control, which reflects a deteriorative estrangement, and distorted perception of capacities, which reveals a restorative estrangement. These findings indicate that subjective self-reports help us to understand some aspects of the potential phenomenon of DBS-induced self-estrangement. (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.

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.
