What kind of reality is legal reality, how is it created, and what are its a priori foundations? These are the central questions asked by the early phenomenologists who took interest in social ontology and law. While Reinach represents the well-known “realist” approach to phenomenology of law, Felix Kaufmann and Fritz Schreier belonged to the “positivist” “Vienna School of Jurisprudence,” combining Hans Kelsen’s Pure Theory of Law with Edmund Husserl’s phenomenology—and thereby challenging Reinach’s views on how legal reality and the (...) legal a priori were to be conceived. This paper addresses the controversy between these positivist and realist approaches to phenomenology of law, with the goal of introducing the lesser known theories of Kaufmann and Schreier. The special focus on their critique of Reinach’s outline should give us an overview of their positions vis-à-vis the basic and a priori elements of which legal reality consists and the role that phenomenology plays in analyzing them. There is one general tendency to be noted: While the phenomenological legal positivists see the root of legal reality in an act of interpretation according to a “normative scheme of interpretation,” Reinach locates the roots of legal reality in social interaction and argues for the existence of entities independent of any interpretation.

When you and I share an experience, each of us lives through a we-experience. The paper claims that we-experiences have unique phenomenality and structure. First, we-experiences’ phenomenality is characterised by the fact that they feel like ours to their subject. This specific phenomenality is contended to derive from the way these experiences self-represent: a we-experience exemplifies us-ness or togetherness because it self-represents as mine qua ours. Second, living through a we-experience together with somebody else is not to have this experience (...) in parallel with the experience of the other. Rather, the paper argues that a we-experience is partly co-constituted by the experience of the other. After offering an account of the phenomenality and constitution of we-experiences, which traces these two elements back to the subject’s self-understanding as a group member, the paper argues for the claim that an experience’s for-us-ness is committal to this experience being co-constituted by another we-experience.

In this study, we analyse the notion of “differential heterogenesis” proposed by Deleuze and Guattari on a morphogenetic perspective. We propose a mathematical framework to envisage the emergence of singular forms from the assemblages of heterogeneous operators. In opposition to the kind of differential calculus that is usually adopted in mathematical-physical modelling, which tends to assume a homogeneous differential equation applied to an entire homogeneous region, heterogenesis allows differential constraints of qualitatively different kinds in different points of space and time. (...) These constraints can then change in time, opening the possibility for new kinds of differential dynamics and the emergence of distinct entities and forms. Formally, we show that operators with different phase spaces can be assembled on the basis of a result of Rothschild & Stein (1976. Hypoelliptic differential operators and nilpotent groups. Acta Mathematica 137. 247–320). Furthermore, operators with different dynamics can be assembled by means of a partition of the unit.After stating the concept of differential heterogenesis in terms of contemporary mathematics, we show that this construction sheds light on the constitution of the semiotic function. In fact, both the Merleau-Pontian and the Deleuzian approaches share a common conceptualisation of the semiotic function and its emergence in terms of amorphodynamics of heterogeneous assemblages with a divergent actualisation. This divergent actualisation allows the co-constitution of various expression and content planes. Finally, we show that the divergent actualisation can be interpreted as the directions of principal eigenvectors of the actualized flow. (shrink)

The dominant conception of delusion in psychiatry (in textbooks, research papers, diagnostic manuals, etc.) is predominantly epistemic. Delusions are almost always characterized in terms of their epistemic defects, i.e., defects with respect to evidence, reasoning, judgment, etc. However, there is an individualistic bias in the epistemic conception; the alleged epistemic defects and abnormalities in delusions relate to individualistic epistemic processes rather than social epistemic processes. We endorse the social epistemological turn in recent philosophical epistemology, and claim that a corresponding turn (...) is needed in the study of delusions. It is a turn from the (purely) individualistic conception, which characterizes delusions only by individualistic epistemic defects and abnormalities, to the (partially) social epistemic conception, which characterizes delusions by individualistic as well as social epistemic defects and abnormalities. This paper is intended as an initial step toward such a social epistemological turn. In particular, we will develop a new model of the development of delusions according to which testimonial abnormalities, including testimonial isolation and testimonial discount, are a causal factor in the development of delusions.

We show that the semi-linear ordering principle for continuous functions implies the determinacy of all Wadge and Lipschitz games.

Zygon®, Volume 56, Issue 4, Page 1058-1069, December 2021.

We prove that the determinacy of all Lipschitz games, the determinacy of all Wadge games, and the semi-linear ordering principle for Lipschitz maps are all equivalent.

This contributed volume aims to reconsider the concept of individuation, clarifying its articulation with respect to contemporary problems in perceptual, neural, developmental, semiotic and social morphogenesis. The authors approach the ontogenetical issue by taking into account the morphogenetical process, involving the concept of individuation proposed by Gilbert Simondon and Gilles Deleuze. The target audience primarily comprises experts in the field but the book may also be beneficial for graduate students. The challenge of the genesis and constitution of "units" has always (...) been at the center of philosophical and scientific research. This ontogenetical issue is common to every discipline but it is articulated in different ways: in phenomenology of perception the constitution of perceptual units is at the base of gestalt field theories, in theoretical neuroscience synchronized neural assemblies are considered as correlates of conscious processes, in developmental embryogenesis the constitution of organs is the principle outcome of morphodynamic evolution while in social morphogenesis the constitution of coherent units is common to segmentary, gerarchic and functional differentiation.

In this brief discussion, we explicate and evaluate Heyes and colleagues’ deflationary approach to interpreting apparent evidence of domain-specific processes for social percep- tion. We argue that the deflationary approach sheds important light on how functionally specific processes in social perception can be subserved at least in part by domain-general processes. On the other hand, we also argue that the fruitfulness of this approach has been unnecessarily hampered by a contrastive conception of the relationship between domain- general and domain-specific processes. (...) As an alternative, we propose a complementary conception: the identification of domain-general processes that are engaged in instances of social perception can play a positive, structuring role by adding additional constraints to be accounted for in modelling the domain-specific processes that are also involved in such instances.

Este artículo presenta un enfoque del problema de la relación entre abducción y percepción en la filosofía de C. S. Peirce, tratando de mostrar la percepción y la abducción, o hipótesis, como procesos creativos capaces de introducir una novedad en el conocimiento. En primer lugar se muestra cómo cada conocimiento, incluso el lógico, está fundamentado en la experiencia de la percepción, y cómo esta presupone una continuidad cosmológica entre la mente y el mundo para poder funcionar. Sucesivamente se pone en (...) evidencia cómo la hipótesis no es nada más que aquel procedimiento que reconoce, como un relámpago, esta continuidad cosmológica de experiencia entre la mente y el mundo. Finalmente, la abducción se configura como un razonamiento que, libremente, obstruye y modifica el flujo continuo de. (shrink)

This paper describes a class of social acts called “violent acts” and distinguishes them from damaging acts. The former are successfully performed if they are apprehended by the victim, while the latter, being not social, are successful only as long as the intended damage is realized. It is argued that violent acts, if successful, generate a social relation which include the aggressor, the victim and, if the concomitant damaging act is satisfied, the damage itself.

The theme of conspiracies plays a key role in Machiavelli's writings, in which can be found considerations and analyses on the use of conspiracy as an instrument of conquest of power, and as a technique for political fighting. This volume denies an interpretation in which Machiavelli limited himself to warning against conspiracies, judging them as a dangerous and useless tool. In reality, he elaborated a real phenomenology or anatomy of the conspiracy. His thoughts on this theme represent a practical manual (...) for the "coup d'état" and the violent seizure of power. But as always, they also contain brilliant intuitions on political psychology, the sociology of power, and social anthropology. (shrink)

Alfred North Whitehead famously compares the philosophical method of knowledge acquisition with the process of flying an airplane. Likewise, “shamanic flight” marks stages of cognitive processing in navigation through perceptible and imperceptible worlds. This article focuses on the cosmovision of the Amazon people Huni Kuin, the Whiteheadian method of imaginative rationalization, and the concept of Amerindian perspectivism. This study also investigates shamanism as an experience of knowledge generation. Furthermore, “shamanic flight,” as an ecstatic technique experienced in many diverse Amerindian rituals, (...) will be explored as a method in the discovery and organization of nonhuman alterities. Finally, Amazonian-based shamanic epistemology will be discussed within a “multinaturalist” ontology. (shrink)

Whiteheadian concepts of life, food, "empty" and "occupied space" provide a theoretical basis to unpack an ontogenetic perspective on aging. Focusing on the so-called "Selective Optimization with Compensation " strategy, this work will explore this concept in relation to some scientific evidence in the fields of "epigenetics " and molecular nutrition. Further, the role of caloric restriction in health and longevity will be discussed as a SOC strategy, based on the metabolic theory of aging. SOC strategy applied to the processes (...) of aging, when linked with Whitehead's philosophy of organism, makes it possible for us to think about life as a selective process provided by "empty space. " A continuum within the physical field optimizes a "living society," which evolves in permanent social deficit, by means of compensation by nutritional metabolism. (shrink)

Most model checking techniques for security protocols make a number of simplifying assumptions on the protocol and/or on its execution environment that greatly complicate or even prevent their applicability in some important cases. For instance, most techniques assume that communication between honest principals is controlled by a Dolev-Yao intruder, i.e. a malicious agent capable to overhear, divert, and fake messages. Yet we might be interested in establishing the security of a protocol that relies on a less unsecure channel (e.g. a (...) confidential channel provided by some other protocol sitting lower in the protocol stack). In this paper we propose a general model for security protocols based on the set-rewriting formalism that, coupled with the use of LTL, allows for the specification of assumptions on principals and communication channels as well as of complex security properties that are normally not handled by state-of-the-art security protocol analysers. By using our approach we have been able to formalise all the assumptions required by the ASW protocol for optimistic fair exchange and some of its key security properties. Besides the previously reported attacks on the protocol, we report a new attack on a patched version of the protocol. (shrink)

O propósito deste artigo é mostrar a relação entre a experiência perceptiva e o raciocínio abdutivo em C.S. Peirce. Ademais, apresento a abdução como uma expressão lógica, prática e criativa apta a introduzir uma novidade no reino do conhecimento, através de um sistema de signos gráficos. A noção peirciana de experiência está relacionada com a de uma práxis interpretativa e criativa, que não se limita ao recebimento ou registro de dados pré-constituídos passivamente. Nesse sentido, a abdução é o hábito lógico (...) vivo que explica o mundo percebido como um caso particular de um mundo concebível, no qual uma regra geral ou hipótese é efetivo. Apresentarei a abdução como um raciocínio que infere a causa a partir do efeito, o antecedente a partir do consequente, a ordem geral de um fato percebido particular e um “extra comum”. A abdução não apenas estabelece um fato singular, mas torna o fato visível dentro de um novo contexto de relações possíveis. Assim, quando vemos uma figura, nós não vemos somente uma mera figura, mas uma figura “como se” ela fosse o resultado percebido de um sistema geral de relações possíveis. O gesto da mão dá existência à figura e a torna visível para nós, pois ela descobre essas relações que constituem o contexto de interpretação da figura. Nesse aspecto, o gesto gráfico consiste na concretização prática que permite uma interpretação topológica possível do mundo real percebido. (shrink)

Wittgenstein has written a great number of remarks relevant to aesthetical issues: he has questioned the relation between aesthetics and psychology as well as the status of our norms of judgment; he has drawn philosophers attention to such topics as aspect-seeing and aspect-dawning, and has brought insights into the nature of our aesthetic reactions. The examination of this wide range of topics is far from being completed, and the purpose of this book is to contribute to such completion. It gathers (...) both papers discussing some of Wittgenstein s most provocative and intriguing statements on aesthetics, and papers bringing out their implications for art critic and art history, as well as their significance to epistemology and to the study of human mind.".

Assuming AD + DC, we characterize the self-dual boldface pointclasses which are strictly larger than the pointclasses contained in them: these are exactly the clopen sets, the collections of all sets of Wadge rank [Formula: see text], and those of Wadge rank [Formula: see text] when ξ is limit.

By recent work on some conjectures of Pillay, each definably compact group G in a saturated o-minimal expansion of an ordered field has a normal "infinitesimal subgroup" G00 such that the quotient G/G00, equipped with the "logic topology", is a compact (real) Lie group. Our first result is that the functor G → G/G00 sends exact sequences of definably compact groups into exact sequences of Lie groups. We then study the connections between the Lie group G/G00 and the o-minimal spectrum (...) G̃ of G. We prove that G/G00 is a topological quotient of G̃. We thus obtain a natural homomorphism ψ* from the cohomology of G/G00 to the (Čech-)cohomology of G̃. We show that if G00 satisfies a suitable contractibility conjecture then $\widetilde{G^{00}}$ is acyclic in Čech cohomology and ψ* is an isomorphism. Finally we prove the conjecture in some special cases. (shrink)

L’articolo intende sondare la fondatezza ontologica di una categoria personologica fondamentale, in particolare in ambito ecclesiologico: il “noi”. Tale ricerca si sviluppa soprattutto nella sua rilevanza trinitaria, a partire dall’apporto offerto dal teologo tedesco Heribert Mühlen, il quale, nella sua opera pneumatologica Der Heilige Geist als Person. In der Trinität, bei der Inkarnation und im Gnadenbund: Ich-Du-Wir, approfondisce questo tema insieme ad altre tre parole-chiave: “io”, “tu”, “tra”.

The topology of definable sets in an o-minimal expansion of a group is not fully understood due to the lack of a triangulation theorem. Despite the general validity of the cell decomposition theorem, we do not know whether any definably compact set is a definable CW-complex. Moreover the closure of an o-minimal cell can have arbitrarily high Betti numbers. Nevertheless we prove that the cohomology groups of a definably compact set over an o-minimal expansion of a group are finitely generated (...) and invariant under elementary extensions and expansions of the language.
