Given a family${\cal C}$of infinite subsets of${\Bbb N}$, we study when there is a Borel function$S:2^{\Bbb N} \to 2^{\Bbb N} $such that for every infinite$x \in 2^{\Bbb N} $,$S\left \in {\Cal C}$and$S\left \subseteq x$. We show that the family of homogeneous sets as given by the Nash-Williams’ theorem admits such a Borel selector. However, we also show that the analogous result for Galvin’s lemma is not true by proving that there is an$F_\sigma $tall ideal on${\Bbb N}$without a Borel selector. The (...) proof is not constructive since it is based on complexity considerations. We construct a${\bf{\Pi }}_2^1 $tall ideal on${\Bbb N}$without a tall closed subset. (shrink)

One of the main tools in the study of nonmonotonic consequence relations is the representation of such relations in terms of preferential models. In this paper we give an unified and simpler framework to obtain such representation theorems.

Let be a separable metrizable space. We establish a criteria for the existence of a metrizable globalization for a given continuous partial action of a separable metrizable group G on. If G and are Polish spaces, we show that the globalization is also a Polish space. We also show the existence of an universal globalization for partial actions of Polish groups.

We show that the enveloping space \ of a partial action of a Polish group G on a Polish space \ is a standard Borel space, that is to say, there is a topology \ on \ such that \\) is Polish and the quotient Borel structure on \ is equal to \\). To prove this result we show a generalization of a theorem of Burgess about Borel selectors for the orbit equivalence relation induced by a group action and also (...) show that some properties of the Vaught’s transform are valid for partial actions of groups.

Several tasks in artificial intelligence require the ability to find models about knowledge dynamics. They include belief revision, fusion and belief merging, and abduction. In this paper, we exploit the algebraic framework of mathematical morphology in the context of propositional logic and define operations such as dilation or erosion of a set of formulas. We derive concrete operators, based on a semantic approach, that have an intuitive interpretation and that are formally well behaved, to perform revision, fusion and abduction. Computation (...) and tractability are addressed, and simple examples illustrate the main results. (shrink)

First published in 1917 and 1918, with a second edition in 1946, this is the first English translation of Santi Romano's classic work, L'ordinamento giuridico. The main focus of The Legal Order is the notion of institution, which Romano considers to be both the core and distinguishing feature of law. After criticising accounts of the nature of law centred on notions of rule, coercion or authority, he offers a compelling conception, not merely of law as an institution, but of the (...) institution as 'the first, original and essential manifestation of law'. Romano advances a definition of a legal institution as any group who share rules within a bounded context: for example, a family, a firm, a factory, a prison, an association, a church, an illegal organisation, a state, the community of states, and so on. Therefore, this understanding of legal institutionalism at the same time provides a ground-breaking theory of legal pluralism whereby 'there are as many legal orders as institutions'. The acme of a jurisprudential current long overlooked in the Anglophone environment, The Legal Order not only proposes what Carl Schmitt described as a 'very significant theory', but, more importantly, it offers precious insights for a thorough rethinking of the relationship between law and society in today's world.

In this study, we examine the influence of senior leadership on firms’ corporate social responsibility. We integrate upper echelons research that has investigated either the influence of the CEO or the top management team on CSR. We contend that functional experience complementarity between CEOs and TMTs in formulating and implementing CSR strategy may underlie differentiated strategies in CSR. We find that when CEOs who have predominant experience in output functions are complemented by TMTs with a lower proportion of members who (...) have experience in output functions, there is a pronounced effect on the community, product, and diversity dimensions of CSR. In turn, when output-oriented CEOs are complemented by output-oriented TMTs, we observe an effect on the employee relations dimension of CSR. Interestingly, we find no influence of CEO-TMT complementarity on the environment dimension of CSR. In general, our empirical results support the relevance of the interaction between CEOs and their TMTs in defining their firms’ CSR profile. (shrink)

This article problematizes the recent comeback of the exceptionalist jargon as it is conjured by both critics and sympathizers. While in the last decades governments across the globe had recourse to emergency measures to cope with far-reaching emergencies, from terrorism to the COVID-19 pandemic, the received view has it that political power takes advantage of states of emergency as they put themselves in the position to circumvent constitutional limitations. Carl Schmitt is claimed to be the major advocate of this conception (...) of emergency politics in that he elaborated on the concept of the state of exception as the heart of the state political power. This article contends that the received view is doubly wrong. First, soon after his espousal of exceptionalism, Schmitt realized that emergency legislation is an ineffective and costly governmental device that should be transitory and is as unstable as the crisis it is meant to overcome. Second, the received view neglects how Schmitt came to his model of ultraconservative substantive constitutionalism as he maintained that the main task of politics is to protect the normative life of a limited set of state-sponsored institutions as well as the substantive contents they produce.

In the recent literature on militant democracy, two claims are made on the relation between its most famous advocate, Karl Loewenstein, and German jurist Carl Schmitt. The first claim is that, although the latter came to support the Nazi regime, in the late 1920s he provided an early model of militant democracy that looks more robust and elaborated than Loewenstein’s. Schmitt’s constrained democracy is believed to cut deeper into that which militancy is supposed to safeguard. The second claim is that (...) this latter model underlies other versions of militant democracy, including Loewenstein’s. This article argues that the first claim is largely correct while the second is to be rejected. In doing so, it delves deep into Schmitt’s understanding of the materiality of law, that is, the social normativity that he believed the constitution was designed to protect, and casts light on the procedural orientation of Loewenstein’s militant democracy. The conclusion is that both these theories espouse a form of conservatism, though different from one another, and that in different ways both can be detrimental to democracy. (shrink)

The Somatic Mutation Theory has been challenged on its fundamentals by the Tissue Organization Field Theory of Carcinogenesis. However, a recent publication has questioned whether TOFT could be a valid alternative theory of carcinogenesis to that presented by SMT. Herein we critically review arguments supporting the irreducible opposition between the two theoretical approaches by highlighting differences regarding the philosophical, methodological and experimental approaches on which they respectively rely. We conclude that SMT has not explained carcinogenesis due to severe epistemological and (...) empirical shortcomings, while TOFT is gaining momentum. The main issue is actually to submit SMT to rigorous testing. This concern includes the imperatives to seek evidence for disproving one’s hypothesis, and to consider the whole, and not just selective evidence. (shrink)

Las experiencias de unio mystica alcanzadas por Plotino encuentran su reflejo en los escritos que los pensadores gnósticos utilizan en sus discusiones con este en Roma, tal como describen Zostrianos (NH VIII, 1) y Allógenes (NH XI, 3). A pesar de dicha rivalidad filosófica, es posible encontrar similitudes entre los testimonios si analizamos estas experiencias a través de su relación con los denominados Estados Alterados de Consciencia (EAC), concepto propuesto por la psicología de la religión. Tanto el corpus filosófico como (...) la tradición gnóstica describen este estado particular del alma (ψυχἠ) al detallar el proceso mistico. En dicho proceso destaca para ambos el cambio profundo en la consciencia del iniciado, aunque neoplatónicos y gnósticos difieren en los límites de identificación con la divinidad.De esta forma, a través del análisis textual y filológico, centraremos el presente trabajo en el estudio de la unio mystica en dos aspectos. Por una parte, en el proceso mismo seguido por el iniciado. Por otra, en el grado de unión o contacto del visionario-iniciado con el Absoluto o la divinidad. Dicho análisis subrayará los caminos comunes que impulsaban ambas escuelas de pensamiento en su búsqueda de lo trascendente, a la vez que planteará preguntas esenciales sobre dicho proceso que delimitarán claramente las diferencias entre las mismas.

This article offers an in-depth analysis of Carl Schmitt's social ontology to explain how and why he came to reject exceptionalist decisionism. To this end, the authors unearth the considerable shifts in terms of social ontology that paved the way for this conceptual turn. The gist of their argument is that Schmitt's Political Theology (1922) espoused a Hobbesian conception of the political as the possibility condition for stable patters of social interaction. Though the first three chapters of Political Theology were (...) originally designed for and published in a posthumous Festschrift for Max Weber, his understanding of the social was indebted to a Hobbesian legacy. Nonetheless, shortly thereafter, he began to revise his conception of the social and to put stress on the organisational dynamics of social institutions as independent of there being a political authority. From 1927 through to 1950, Schmitt never got back to his 1922 exceptionalist view of politics and rather sought to make sense of how the state could and should draw the contents of the legal order from the normative life of social institutions.

In science it is obvious that we are certain about many things, but among philosophers there is little agreement as to why we know these things. In Knowing Things for Sure physicist and realist philosopher, Mariano Artigas traces the confusion to non-realist philosophies and argues that practitioners of experimental science do reach logical truths about reality.

Transhumanism is a scientific and philosophical movement that proposes to overcome, through new technologies, the restrictions imposed on us by our biological condition. Some transhumanists assume that the struggle against natural limits could lead to a radical change in our body or even to its replacement. Other authors, such as Nicholas Agar, propose a moderate enhancement that does not exceed the framework of what we understand to be human. In this article, I will offer a plausible interpretation of the project (...) of human enhancement from a Thomistic perspective. To carry out my analysis, I will focus on three fundamental metaphysical and anthropological questions: How do advocates of radical enhancement understand the relationship between limits, imperfections and evils in human nature? How is this relationship understood from moderate positions? And Is any of these proposals compatible with Aquinas’ anthropology? I will conclude that the identification of limits with imperfections and evils assumed by radical positions is incompatible with Aquinas’ anthropology. Nevertheless, this does not entail that any bio-modification is unacceptable. Aquinas’ peculiar metaphysics, together with its anthropology in which the natural, the supernatural and the preternatural realms intertwine, can offer an interesting framework to assess the human enhancement project.

ABSTRACTThis article offers an unconventional interpretation of Carl Schmitt’s conception of the political. It first identifies two alternative readings – an ‘exceptionalist’ and a ‘concretist’ one – to make the claim that in the late 1920s he laid the foundations for a theory of politics that overcame the flaws of his theory of exception. It then explains why the concretist reading provides an insightful key to Schmitt’s take on the relationship between politics and law as a whole. Despite this, the (...) chief aim of this analysis is not interpretive. Rather, the article claims that such a paradigm change was related to Schmitt’s pondering on the elements that were menacing to draw the experience of modern statehood to an end even more seriously than any upheavals and revolutions. For he came to the conclusion that the mere claim to political self-sufficiency on the part on non-state social entities was able to defy the idea of the state as the political entity par excellence. While these reflections urged Schmitt to reformulate many features of his conception of the political, the article contends that this particular juncture in his production sheds light on a crucial feature of contemporary politics.

Husserl va haciéndose consciente de que el ideal “racionalista” de la razón no hace justicia por sí solo a la riqueza de la vida moral. La vida lograda no consistiría solamente en conducir ésta de acuerdo con el ideal de la razón, sino en dejarse mover por el amor. Éste presenta dos características: revela la individualidad de la persona que ama y de la persona amada y funda una “comunidad del tender” con la(s) persona(s) amada(s).

In developed countries, companies are now substantially reliant on the skills and abilities of their leaders to tackle a variety of complex issues. There is a growing consensus that leadership development training and assessment methods should adopt more holistic methodologies, including those associated with the emotional and neuroendocrine aspects of learning. Recent research into the assessment of leadership competencies has proposed the use of objective methods and measurements based on neuroscience. One of the challenges to be faced in the development (...) of a performance-based methodology to measure leadership skills is how to generate real-life situations with triggers that allow us to study management competencies under controlled laboratory conditions. A way to address this question is to take advantage of virtual environments to recreate real-life situations that might arise in performance-based assessments. We propose virtual reality (VR) as a very promising tool to observe various leadership related behavioral patterns during dynamic, complex and realistic situations. By seamlessly embedding assessment methods into virtual learning environments, VR can provide objective assessment methods with high ecological validity. VR also holds unlimited opportunities for leadership training providing subjects with intelligent tutoring systems that adapts situations in real time according to the observed behaviors. (shrink)

Different cell lineages growing in microgravity undergo a spontaneous transition leading to the emergence of two distinct phenotypes. By returning these populations in a normal gravitational field, the two phenotypes collapse, recovering their original configuration. In this review, we hypothesize that, once the gravitational constraint is removed, the system freely explores its phenotypic space, while, when in a gravitational field, cells are “constrained” to adopt only one favored configuration. We suggest that the genome allows for a wide range of “possibilities” (...) but it is unable per se to choose among them: the emergence of a specific phenotype is enabled by physical constraints that drive the system toward a preferred solution. These findings may help in understanding how cells and tissues behave in both development and cancer. In microgravity, cells undergo spontaneous and reversible transitions between different phenotypes. In the absence of physical constraints, living systems could yield bi-stable decisions. On the contrary, physical ‘boundaries’ constrain cells to acquire only a specific configuration by selecting and shaping different gene expression patterns provided by the intrinsic genetic stochasticity.

Moritz Geiger was one of the most significant members of the early phase of the phenomenological movement. His work on the consciousness of feelings constitutes an example of careful phenomenological analysis. The central question Geiger raised is this: how are feelings given to consciousness when they are “fully lived”? As I seek to prove, the principal result of his analysis is to point out a way of being oriented towards feelings without objectifying them. Geiger’s analysis of the consciousness of feelings (...) is a masterpiece of phenomenological precision. It is reasonable to think that it influenced the way Husserl conceived of something so decisive as emotive intentionality. (shrink)

In this article I contend that the re-emergence of religion in Western liberal states is a feature of a much broader phenomenon, namely, the re-establishment of legal pluralism whereby various social actors claim to be the legitimate producers of their own law. To prove this, I first offer an account of secularization as the successful attempt of modern states to dismantle a legal-pluralist system. Based on this, I argue that the reviviscence of religions is the reviviscence of their practical side: (...) religious practices tend to be perceived by religious group members as providing guidance for conduct, one that challenges the rules of the state legal order and its monistic structure. Finally, by exploring the issue of same-sex union recognition, I defend the claim that, in a truly post-secular society, the state should allow a multiplicity of relationship-recognition models that reflect and meet different interests and needs.

This article centres on the legal recognition of same-sex marriage with a view to exploring the issue of unspeakability; that is, the condition whereby some questions cannot be articulated because of a lack of words. More specifically, the article will explore what happens to those social practices that are not given legal speakability and thereby legal recognition/protection. To this end, I first focus on how words are produced in the sphere of everyday life and their dependence on the existence of (...) a widespread normality. I then discuss how the law sees to the preservation and the reproduction of normality by providing a set of categories which are made available to law-abiders to settle disputes when they arise. In doing so, I elucidate the twofold role played by law as both a selective and a creative device. To cast some light on the particular way law operates, I discuss an important decision by the Italian Constitutional Court in 2010, which provides a telling example of how legal officials are able to seal off the set of legal categories and to leave some issues in the sphere of the unspeakable. I then unearth a paradox: while unspeakability reveals a condition of powerlessness, the acquisition of speakability could bring about even harsher exclusionary effects. I conclude by arguing that the entry into the sphere of official law is always a Janus-faced achievement, but can play as an effective instrument of critique. (shrink)

En este trabajo se analiza el concepto de Estado racional mediante tres perspectivas que de modo explícito o implícito se encuentran en el Fundamento del derecho natural de Fichte. Con la intención de mostrar la centralidad del concepto de Estado, en primer lugar se trata la perspectiva de la superfluidad y sus límites ; en segundo lugar se trata la perspectiva de la coacción, que también brinda un concepto de Estado negativo. En tercer lugar se trata la perspectiva que, sin (...) caracterizarlo negativamente, no obstante no alcanza una comprensión positiva del Estado, donde éste sea el concepto central de la filosofía social, política y económica de Fichte. Finalmente, a partir de El Estado comercial cerrado y Los caracteres de la edad contemporánea se esboza una clasificación sobre los diferentes conceptos de Estado desarrollados y contenidos bajo una unidad de sentido.
