El presente escrito propone una estrategia de lectura para las complejas reflexiones tardías de Merleau-Ponty en torno al concepto de carne. Se sostendrá en el desarrollo del artículo que esta noción debe ser comprendida a partir de las características propias del tipo de ontología que el autor pretende construir y de las notas distintivas de su objeto de estudio. Una vez explicitados estos fundamentos, ellos funcionan como un marco exegético de la problemática de la carne y como guía ordenadora (...) de los elementos que la componen. De acuerdo con esta premisa, el trabajo consta de tres partes. En la primera se expondrá lo que consideramos los rasgos principales de la ontología merleau-pontiana de sus últimos años de producción y el modo en que esta se configura para posicionar la experiencia sensorial como un legítimo objeto de estudio. En la segunda y en la tercera parte se analizará, a través del prisma de lo desarrollado, la cuestión de la carne sobre la base de una propuesta de lectura específica que involucra una dinámica específica entre los conceptos de diferencia y unidad.

We prove that the category of Nachbin’s compact ordered spaces and order-preserving continuous maps between them is dually equivalent to a variety of algebras, with operations of at most countable arity. Furthermore, we observe that the countable bound on the arity is the best possible: the category of compact ordered spaces is not dually equivalent to any variety of finitary algebras. Indeed, the following stronger results hold: the category of compact ordered spaces is not dually equivalent to any finitely accessible (...) category, any first-order definable class of structures, and any class of finitary algebras closed under products and subalgebras. An explicit equational axiomatisation of the dual of the category of compact ordered spaces is obtained; in fact, we provide a finite one, meaning that our description uses only finitely many function symbols and finitely many equational axioms. In preparation for the latter result, we establish a generalisation of a celebrated theorem by Mundici: our result—whose proof is independent of Mundici’s theorem—asserts that the category of unital commutative distributive lattice-ordered monoids is equivalent to the category of what we call MV-monoidal algebras.Abstract taken directly from the thesis.E-mail: marco[email protected]: https://air.unimi.it/retrieve/handle/2434/812809/1698986/phd_unimi_R11882.pdf.

This paper aims to envisage neoliberal capitalism through the prism of the Marxian notion of «primitive accumulation» and to verify this theoretical framework in contemporary Chile. The first part is an exploration of the actual debate about the notion of primitive accumulation. The second part characterizes neoliberal capitalism as a new form of primitive accumulation. For this I identify an objective pole, which I will call neoliberalism as a form of «dispossession» and a subjective pole, as a part of a (...) I will call neoliberalism as a form of technology. In the third part I will use the post-coup period in Chile to shed light on the founder function of violence in neoliberal capitalism. (shrink)

El presente trabajo se propone reflexionar en torno al vínculo entre la noción de agencia material y el pensamiento posthumanista contemporáneo. Mas específicamente nos proponemos cuestionar la necesidad de que una postura filosófica no antropocéntrica deba contener necesariamente una concepción simétrica de agencia. Para esto, en primer lugar, se analizarán los desarrollos de Lambros Malafouris en torno a dicha problemática, con el fin de caracterizar una concepción simétrica de la capacidad agentiva. En contraposición a esto, en segundo término, se explicitará (...) la visión de Tim Ingold al respecto, con el fin de abrir paso a un nuevo enfoque. (shrink)

La presente reflexión se propone explorar los tratamientos de antropólogo Tim Ingold en torno al concepto de ambiente. El objetivo será desprender de ellos un aporte hacia una concepción no antropocéntrica de la noción de naturaleza. Clasificaremos los planteos del autor en dos grandes teorías que estructurarán las diferentes secciones del trabajo: por un lado su “teoría de los materiales”, y por el otro, su “teoría de las líneas”. En la primera analizaremos las bases que conforman su concepción del ambiente (...) fundada en la contraposición materialidad vs. materiales. En la segunda parte analizaremos su denominada linealogía a partir de tres figuras: nudo, suelo y aire. De la conjunción de ambas teorías se deriva un concepto de naturaleza renovado que armoniza con las coordenadas de los nuevos materialismos y posthumanismos contemporáneos. Nuestra hipótesis es que en los planteos del antropólogo se trasluce una comprensión de naturaleza en términos intersticiales. Más específicamente, se pone el acento ya no en la relación entre un humano espectador y una naturaleza como escenario, sino en la tensión entre el ambiente y la experiencia, concebidas ambas esferas como mutuamente conformantes.

El trabajo se propone pensar el estatuto de la técnica en el marxismo operaísta y postoperaísta y los objetivo que tiene son tres. En primer lugar mostrar cómo una concepción de la técnica que podemos definir como anti instrumental, sobre todo en virtud del postulado de anti-neutralidad valorativa que acarrea, subyace a los planteamientos operaístas. En segundo lugar elucidar cómo esta perspectiva constituye una línea de continuidad entre el primer operaísmo y los trabajos contemporáneos de autores postoperaístas como Negri y (...) Virno. En tercer lugar plantear que un punto de ruptura conceptual importante entre el operaísmo y el «marxismo oficial» reside en la distintas formas de pensar el espacio en que se producen valores de uso. A partir de la diferenciación entre neutralidad metodológica y neutralidad fáctica postulada por Rapp, defenderemos que ambas perspectivas rechazan la neutralidad valorativa de los medios de producción, pero no piensan la neutralidad de la misma manera.

La noción de carne, perteneciente a la última etapa del pensamiento de Merleau-Ponty, ocupa un lugar determinante en las investigaciones especializadas sobre el autor. Sin embargo, en escasas publicaciones se destaca la inmensa influencia de esta última en el pensamiento actual, especialmente en las corrientes posthumanistas y materialistas de la contemporaneidad filosófica. Nos proponemos, en las páginas que siguen, analizar dicha categoría desde el punto de vista de una filosofía de la relación, interpretándola desde la figura de la medialidad o (...) emparentándola a una noción de medio. Para esto, en la primera parte, se dilucidará la noción merleau-pontiana de medio en _Fenomenología de la percepción_ y la postulación de la experiencia como punto de partida. En la segunda, se explicitarán las múltiples dimensiones en las cuales se despliega la noción de carne en la filosofía tardía del autor. Una vez abordados los aspectos epistemológico, fenomenológico y ontológico de la ontología de la carne se analizará su potencial filosófico proyectando los tratamientos a la problemática de la naturaleza, cuestión que consideramos de vital importancia para las reflexiones filosóficas actuales.

Las reflexiones que conforman el presente artículo intentan brindar un aporte a la cuestión de la naturaleza y de la problemática medioambiental desde el punto de vista de lo que denominaremos una filosofía del suelo. Se emprenderá dicha tarea a través de los planteos de una serie de autores y autoras pertenecientes a la contemporaneidad filosófica, que se han preocupado, en distinta medida y de modos muy diferentes, por la problemática de la tierra o el suelo: Donna Haraway, Tim Ingold (...) y Bruno Latour. Para esto, nos serviremos de una serie de elementos que extraeremos de la experiencia visual y táctil de las Líneas de Nazca, legado de nuestro pasado amerindio en el desierto peruano. El trabajo se dividirá en tres partes, dedicada cada una de ellas a explicitar ciertas reflexiones de los autores que puedan asociarse a una filosofía como la que pretendemos mentar. El enfoque priorizará los entrelazos entre los mismos y el desarrollo de elementos que nos permitan un entrecruzamiento de sus respectivas teorías. (shrink)

El artículo se propone abordar el concepto de multitud tal y como ha sido elaborado por el filósofo italiano Antonio Negri, incluyendo los trabajos escritos con Michael Hardt. El texto reconstruye la oposición del concepto de multitud al de pueblo, central en el pensamiento y en las instituciones políticas modernas; y la diferencia entre el concepto de multitud y el de clase obrera moderna, del que va más allá. Finalmente se hará hincapié en el pasaje del ser al hacer multitud.

The classification of medical interventions as either invasive or non-invasive is commonly regarded to be morally important. On the most commonly endorsed account of invasiveness, a medical intervention is invasive if and only if it involves either breaking the skin (‘incision’) or inserting an object into the body (‘insertion’). Building on recent discussions of the concept of invasiveness, we show that this standard account fails to capture three aspects of existing usage of the concept of invasiveness in relation to medical (...) interventions—namely, (1) usage implying that invasiveness comes in degrees, (2) that the invasiveness of an intervention can depend on the characteristics of the salient alternative interventions, and (3) that medical interventions can be invasive in non-physical ways. We then offer the beginnings of a revised account that, we argue, is able to capture a wider range of existing usage. Central to our account is a distinction between two properties: basic invasiveness and threshold invasiveness. We end by assessing what the standard account gets right, and what more needs to be done to complete our schematic account. (shrink)

A spatial logic is a formal language interpreted over any class of structures featuring geometrical entities and relations, broadly construed. In the past decade, spatial logics have attracted much attention in response to developments in such diverse fields as Artificial Intelligence, Database Theory, Physics, and Philosophy. The aim of this handbook is to create, for the first time, a systematic account of the field of spatial logic. The book comprises a general introduction, followed by fourteen chapters by invited authors. Each (...) chapter provides a self-contained overview of its topic, describing the principal results obtained to date, explaining the methods used to obtain them, and listing the most important open problems. Jointly, these contributions constitute a comprehensive survey of this rapidly expanding subject. (shrink)

Computational models of meaning trained on naturally occurring text successfully model human performance on tasks involving simple similarity measures, but they characterize meaning in terms of undifferentiated bags of words or topical dimensions. This has led some to question their psychological plausibility (Murphy, 2002;Schunn, 1999). We present here a fully automatic method for extracting a structured and comprehensive set of concept descriptions directly from an English part‐of‐speech‐tagged corpus. Concepts are characterized by weighted properties, enriched with concept–property types that approximate classical (...) relations such as hypernymy and function. Our model outperforms comparable algorithms in cognitive tasks pertaining not only to concept‐internal structures (discovering properties of concepts, grouping properties by property type) but also to inter‐concept relations (clustering into superordinates), suggesting the empirical validity of the property‐based approach.

As neuroscience progresses, we will not only gain a better understanding of how our brains work, but also a better understanding of how to modify them, and as a result, our mental states. An important question we are faced with is whether the state could be justified in implementing such methods on criminal offenders, without their consent, for the purposes of rehabilitation and reduction of recidivism; a practice that is already legal in some jurisdictions. By focusing on a prominent type (...) of view of free action, which I call bypassing views, this paper evaluates how such interventions may negatively impact the freedom of their subjects. The paper concludes that there will be a tension between the goals of rehabilitation and reduction of recidivism, on the one hand, and the negative impact such interventions may have on free action, on the other. Other things equal, the better that a particular intervention is at achieving the former, the more likely it is to result in the latter. (shrink)

. This paper investigates the mechanisms of knowledge production of twenty-first century robotics-inspired morphology. How robotics influences investigations into the structure, development, and change of organic forms? Which definition of form is presupposed by this new approach to the study of form? I answer these questions by investigating how robots are used to understand and generate new questions about the locomotion of extinct animals in the first case study and in high-performance fishes in the second case study. After having illustrated (...) the landscape of twentieth-century morphology, I will reflect on the definition of form adopted in twenty-first century robotics-inspired morphology as well as on the differences between this approach to the study of form and the so-called nature-inspired disciplines, such as bionics or biomimetics. In the conclusion, I suggest that we are now in a material turn in morphology, characterized by the coexistence of the robotic, the virtual, and the real, which enables an understanding of how the structures and dynamics of shapes change over time.

This essay pushes the history of a scientific discipline, morphology, toward a broader philosophically informed and cross-disciplinarily engaged history of knowledge. It shows that by looking at how knowledge and practices circulated between scientific disciplines (such as biology) and technoscientific ones (like architecture and design) we can better understand how (morphological) knowledge was produced. By doing so, the analysis contributes to the study of the mechanisms of knowledge exchange between the organic and the technical worlds and, more broadly, to the (...) study of the dynamics of knowledge circulation. First, the essay analyzes the engineering studies of organic form conducted by the Austro-Hungarian botanist Raoul Heinrich Francé (1874–1943) and the Scottish polymath D’Arcy Wentworth Thompson (1860–1948). Subsequently, the essay moves to twenty-first-century morphogenesis. It examines the transfer of the notion of morphospace, a paleontological practice of data visualization, into biology-inspired architectural design. The conclusion deals with the broader features of knowledge transfer and circulation. Twentieth- and twenty-first-century morphologists successfully translate and transfer morphogenetic processes from nature into technical artifacts to achieve technical solutions to given problems. In the translation of organic morphogenesis into a technical process, evolution’s intrinsic historical contingency was deliberately left behind. (shrink)

Although ethical decision‐making theory has evolved over the years, within the field of management, research still revolves around James Rest’s (1986) four‐step framework, dominated by a positivist epistemology and a quantitative methodology. Given that currently there is a call for a theoretical, epistemological, and methodological renovation for the enlargement and enrichment of knowledge about how decisions are morally made in organizations, this paper has a double aim. First, by showing the models’ main flaws and limitations, it critically assesses the prominent (...) theoretical models of Rest, Trevino, and Jones. Then, for decision making in organizations, the paper aims to posit a fresh moral theory that addresses the phenomenon from a comprehensive epistemological perspective. To do so, it steps back from those prominent models in order to review John Dewey’s “theory of moral life.” At the core of the proposed comprehensive theoretical framework are Dewey’s concepts of a “moral standard” and “valuation.” Finally, the paper shows how the Dewey‐based framework can both overcome the flaws and limitations that are identified in those prominent models and can enrich empirical research, therefore contributing to developing as a whole the ethical decision‐making field.

In the theoretical literature on moral responsibility, one sometimes comes across cases of manipulated agents. In cases of this type, the agent is a victim of wholesale manipulation, involving the implantation of various pro-attitudes (desires, values, etc.) along with the deletion of competing pro-attitudes. As a result of this manipulation, the agent ends up performing some action unlike any that she would have performed were it not for the manipulation. These sorts of cases are sometimes thought to motivate historical views (...) of responsibility, on which the agent’s past is relevant to whether she is responsible for a specific action. In a recent paper, Daniel Sharp and David Wasserman bring these theoretical discussions on moral responsibility to bear on practical issues regarding neurological modifications of individuals. After proposing and arguing for a historical view, Sharp and Wasserman offer some insight into how such a view may help us in determining the responsibility of subjects who have undergone Deep Brain Stimulation. This paper aims to join this discussion, by arguing that the correct historical view to be applied will also appeal to the agent’s control over her mental life and the fact that this was bypassed. I conclude with some brief comments on the practical implications of such a historical view. (shrink)

Business Ethics: A European Review, EarlyView.

The aim of my paper is to compare three alternative formal reconstructions of van Inwagen’s famous argument for incompatibilism. In the first part of my paper, I examine van Inwagen’s own reconstruction within a propositional modal logic. I point out that, due to the expressive limitations of his propositional modal logic, van Inwagen is unable to argue directly (that is, within his formal framework) for incompatibilism. In the second part of my paper, I suggest to reconstruct van Inwagen’s argument within (...) a first-order predicate logic. I show, however, that even though this reconstruction is not susceptible to the same objection, this reconstruction can be shown to be inconsistent (given van Inwagen’s own assumptions). At the end of my paper, I suggest to reconstruct van Inwagen’s argument within a quantified counterfactual logic with propositional quantifiers. I show that within this formal framework van Inwagen would not only be able to argue directly for incompatibilism, he would also be able to argue for crucial assumptions of his argument. (shrink)

This paper treats of Husserl’s phenomenology of happiness or eudaimonia in five parts. In the first part, we argue that phenomenology of happiness is an important albeit relatively neglected area of research, and we show that Husserl engages in it. In the second part, we examine the relationship between phenomenological ethics and virtue ethics. In the third part, we identify and clarify essential aspects of Husserl’s phenomenology of happiness, namely, the nature of the question concerning happiness and the possibility of (...) a phenomenological answer, the power of the will, the role of vocation, the place of obligation, the significance of habituation, the necessity of selfreflection and self-criticism, the importance of sociability and solidarity, the impact of chance and destiny, and the specter of regret. In the fourth part, we establish the inextricable linkage between Husserl’s metaethics and his metaphysics. In the fi ft h part, we provide a provisional exploration of his conception of the connection between happiness and blessedness. We acknowledge that there is an extensive literature on Husserl’s phenomenological ethics, and our study has benefitted greatly from it, but we also suggest that our holistic approach critically clarifies his description of happiness, virtue, and blessedness by fully recognizing that his phenomenological metaethics is embedded in his phenomenological metaphysics.

This paper examines the subversive role of statistics paleontology at the end of the 19th and the beginning of the 20th centuries. In particular, I will focus on German paleontology and its relationship with statistics. I argue that in paleontology, the quantitative method was questioned and strongly limited by the first decade of the 20th century because, as its opponents noted, when the fossil record is treated statistically, it was found to generate results openly in conflict with the Darwinian theory (...) of evolution. Essentially, statistics questions the gradual mode of evolution and the role of natural selection. The main objections to statistics were addressed during the meetings at the Kaiserlich-Königliche Geologische Reichsanstalt in Vienna in the 1880s. After having introduced the statistical treatment of the fossil record, I will use the works of Charles Léo Lesquereux, Joachim Barrande, and Henry Shaler Williams to compare the objections raised in Vienna with how the statistical treatment of the data worked in practice. Furthermore, I will discuss the criticisms of Melchior Neumayr, one of the leading German opponents of statistical paleontology, to show why, and to what extent, statistics were questioned in Vienna. The final part of this paper considers what paleontologists can derive from a statistical notion of data: the necessity of opening a discussion about the completeness and nature of the paleontological data. The Vienna discussion about which method paleontologists should follow offers an interesting case study in order to understand the epistemic tensions within paleontology surrounding Darwin’s theory as well as the variety of non-Darwinian alternatives that emerged from the statistical treatment of the fossil record at the end of the 19th century.

We investigate the major mathematical theories of space from a modal standpoint: topology, affine geometry, metric geometry, and vector algebra. This allows us to see new fine-structure in spatial patterns which suggests analogies across these mathematical theories in terms of modal, temporal, and conditional logics. Throughout the modal walk through space, expressive power is analyzed in terms of language design, bisimulations, and correspondence phenomena. The result is both unification across the areas visited, and the uncovering of interesting new questions.

In Unfit for the Future, Ingmar Persson and Julian Savulescu present a sophisticated argument in defense of the imperative of moral enhancement. They claim that without moral enhancement, the future of humanity is seriously compromised. The possibility of ultimate harm, caused by a dreadful terrorist attack or by a final unpreventable escalation of the present environmental crisis aggravated by the availability of cognitive enhancement, makes moral enhancement a top priority. It may be considered optimistic to think that our present moral (...) capabilities can be successfully improved by means of moral education, moral persuasion, and fear of punishment. So, without moral enhancement, drastic restrictions on human freedom would become the only alternative to prevent those dramatic potential outcomes. In this article, I will try to show that we still have reason to be less pessimistic and that Persson & Savulescu’s arguments are fortunately unconvincing. (shrink)

The legitimacy of conscientious objection to abortion continues to fuel heated debate in Italy. In two recent decisions, the European Committee for Social Rights underlined that conscientious objection places safe, legal, and accessible care and services out of reach for most Italian women and that the measures that Italy has adopted to guarantee free access to abortion services are inadequate. Nevertheless, the Ministry of Health states that current Italian legislation, if appropriately applied, accommodates both the right to conscientious objection and (...) the right to voluntary abortion. One empirical argument used to demonstrate that conscientious objection does not create barriers to abortion is the “no correlation” argument, which the Italian Committee for Bioethics employed to demonstrate that no association exists between conscientious objection and waiting times for voluntary abortion in Italy and to support the weak form of conventional comprise adopted by the Italian legislation to balance the conflict between women’ autonomy and healthcare professionals’ moral integrity. Conversely, we showed how the “no correlation” argument fails to demonstrate the absence of a relationship between the number of conscientious objectors and waiting times for voluntary abortion, and that the limitations of the “no correlation” argument itself demonstrate how it is still difficult to describe the real effect of conscientious objection on the access to abortion services and to evaluate the suitability of conventional compromise to effectively balance conflicting moral principles. Further studies are needed to better describe the relationship between conscientious objection and waiting times for voluntary abortion. If new evidence would show that the increasing proportion of objectors does undermine the efficacy of the Italian law and the right of a woman to freely obtain a voluntary abortion, new ways will need to be found to address the conflict between moral principles and restrict the protection accorded to the principle of moral integrity. This would inevitably imply the need to constrain and to redefine the terms and conditions for claiming conscientious objection. (shrink)

Genetic engineering has been a topic of discussion for over 50 years, but it is only recently that gene editing has become a reality. CRISPR biotechnologies have made gene editing much safer, precise and feasible. We have witnessed the first cases of human germline genetic modification resulting in live births, conducted by He Jiankui. In this paper, we will analyse He Jiankui’s case in relation to one of the most difficult problems in procreative ethics (or the ethics of future generations): (...) the non‐identity problem. We believe that this analysis will help us to understand the ethics involved in gene editing and hopefully allow for a better, more philosophically grounded legislation on CRISPR and other gene‐editing technologies.

Scientific research in the formal sciences comes in multiple degrees of formality: fully formal work; rigorous proofs that practitioners know to be formalizable in principle; and informal work like rough proof sketches and considerations about the advantages and disadvantages of various formal systems. This informal work includes informal and semi-formal debates between formal scientists, e.g. about the acceptability of foundational principles and proposed axiomatizations. In this paper, we propose to use the methodology of structured argumentation theory to produce a formal (...) model of such informal and semi-formal debates in the formal sciences. For this purpose, we propose ASPIC-END, an adaptation of the structured argumentation framework ASPIC+ which can incorporate natural deduction style arguments and explanations. We illustrate the applicability of the framework to debates in the formal sciences by presenting a simple model of some arguments about proposed solutions to the Liar paradox, and by discussing a more extensive—but still preliminary—model of parts of the debate that mathematicians had about the Axiom of Choice in the early twentieth century.

One of the legacies of modern philosophy is to have separated or bifurcated the human from nature. Marco Altamirano offers a critique of the modern concept of nature in order to chart a new trajectory for the philosophy of nature. -/- By examining the history of the concept of nature, Altamirano shows how a spatial and epistemological concept of nature emerged in Descartes, where a subject confronts an object in space and subsequently wonders about her mode of access to (...) that object. He then argues that a time-based concept of nature is necessary in order to reinstall the subject within its eventual ecology. Deploying conceptual resources from Bergson, Deleuze, Guattari, Foucault, and Leroi- Gourhan (among others), Altamirano shows how the concept of technology harbors an escape route from the spatial and epistemological picture of nature. Ultimately, this book draws the profile of a concept of nature based on time and technology that bypasses the nature-artifice distinction that has mired the philosophy of nature since modern philosophy.

The operational perspective here defended permits a reflexive-transcendental point of view that sharply distinguishes the two concepts, while, at the same time, maintaining the connection between them. On the one hand, simply imagining that the experimental apparatus, counterfactually anticipated in a thought experiment, has really been constructed is sufficient to erase any difference between thought and real experiments. On the other hand, this very ‘imagining’, this capacity of the mind to assume every real entity as a possible entity, underpins the (...) difference in principle – a properly transcendental difference – between thought and real experiments. This difference, however, implies the intimate association between experiment and thought experiment: All thought experiments must be thought of as translatable into real ones, and all real experiments as realisations of thought ones. What thought experiments have over and above real experiments is the mere fact that they exist in a purely hypothetical sphere; what real have over and above thought experiments is the mere fact that they overstep the sphere of the possible, in the experiment’s real execution.
