This pioneering book presents a reconstitution of Charles Sanders Peirce philosophical system as a coherent architecture of concepts that form a unified theory of reality. Historically, the majority of Peircean scholars adopted a thematic approach to study isolated topics such as semiotics and pragmatism without taking into account the author’s broader philosophical framework, which led to a poor and fragmented understanding of Peirce’s work. In this volume, professor Ivo Assad Ibri, past president of The Charles Sanders Peirce Society and a (...) leading figure in the Brazilian community of Peircean scholars, adopts a systemic approach to Peirce’s thought and presents Peirce’s scientific metaphysics as a deep ontological architecture based on a semiotic logic and on pragmatism as criteria of meaning. Originally published in Portuguese, this book became a classic among Brazilian Peircean scholars by presenting a conceptual matrix capable of providing a clear reference system to ground the thematic studies into the broader Peircean system. Now translated to English, this reviewed, amplified and updated edition aims to make this contributions available to the international community of Peircean scholars and to serve as a tool to understand Peirce’s work in a more systemic way by integrating concepts such as experience, phenomenon, existence and reality, as well as theories such as Chance, Continuity, Objective Idealism, Cosmology and Pragmatism, in a coherent system that reveals Peirce’s complex metaphysical architecture. "As the philosophical reputation of Charles S. Peirce continues to rise to first-tier prominence in the history of American philosophy, Ivo Ibri’s Kósmos Noetós assumes a unique status in both a pioneering and a magisterial work of transcontinental Peirce scholarship. This original work of this internationally renowned scholar and editor, and Professor of Philosophy at the Pontifical Catholic University of San Paulo, penetrates to the heart of Peirce’s architectonic system of phenomenological, metaphysical, and semiotic categories which heuristically characterize our world as “a universe perfused with signs.” Ibri’s own synergistic commentary on the radiating registers of Peirce’s cosmogonically and pragmatistically conceived “one intelligible theory of the universe” also instructively contributes to the illumination of significant nodes of interface with a range of relevant theoretical trends in the contemporary academy; as well, it places Peirce in the company of such thinkers as Plato, Aristotle, Plotinus, Kant, and Schelling who preceded Peirce in providing a legacy of first-tier reasoning on our intelligibly developing world. Kosmos Noetos impresses as Ibri’s pure, lucid, passionately thought-loving, philosophical articulation of his own and as the indispensable prolegomena to all future Peirce studies." David Dilworth, State University of New York at Stone Brook – USA "Ivo Ibri has offered us in this exquisite work a framing of the inner logic of Charles S. Peirce's core metaphysical vision and its existential implications. It is a deep and nuanced exploration of the internal dynamics of Peirce’s central metaphysical categories, developed through rigorous and detailed attention to the evolution of Peirce’s thought on the ‘vitally important topics’ of the appearing, the reality, and the intelligibility of the world. The two-leveled format of the book, an intricate weaving of Peirce’s texts and discursive elaboration and linkage by Ibri, gives it a distinctive feel and is the bedrock of its value. The book is a remarkable combination of presentation and analysis. It is informed by Ibri’s deep philosophical culture and is a gentle and convincing argument for the centrality of metaphysics in understanding Peirce’s thought. It offers in a new way indispensable suggestions for our own attempts to think about our places in an evolving universe with the aid of Peirce and offers threads of thought to be followed up by others."

Montrer que le rapport de la conversion au Souverain Bien chez Pascal nous invite à ausculter philosophiquement la notion d'émotion : c'est ce que Jean-Louis Bischoff entend montrer dans la présente étude. L'enjeu de son enquête est clair : il entend affoler et subvertir l'approche commune du mot « émotion ». Pour mener à bien son projet, l'auteur mobilise les lumières de philosophes comme Marion, Levinas, Ricoeur, Greisch ou Romano.

As características do teletrabalho podem contribuir tanto para o aumento quanto para a diminuição do estresse do trabalhador. Este estudo buscou identificar os preditores de estresse, em termos de vantagens e desvantagens do teletrabalho, recursos e demandas psicossociais relacionados ao trabalho e interação trabalho-família, entre servidores da Justiça Federal do Rio Grande do Sul que desenvolvem teletrabalho. Os 130 participantes responderam o questionário de dados demográficos e laborais, escala de estresse percebido, vantagens e desvantagens do teletrabalho, recursos-demandas do trabalho e (...) interação trabalho-família. Análise de regressão linear múltipla identificou um modelo preditivo de estresse composto pelas variáveis de interações trabalho-família e família-trabalho negativas, autoeficácia e sobrecarga. Os resultados apontam fatores de risco e proteção para o estresse entre teletrabalhadores. Ressalta-se a necessidade de legislação laboral nacional que regulamente o teletrabalho, de forma a configurá-lo de maneira mais concreta, permitindo ações visando à saúde dos trabalhadores.

In Transparent Intensional Logic we can recognize two distinct notions of computation that loosely correspond to term rewriting and term interpretation as known from lambda calculus. Our goal will be to further explore these two notions and examine some of their properties.

Collective migration is a key process that is critical during development, as well as in physiological and pathophysiological processes including tissue repair, wound healing and cancer. Studies in genetic model organisms have made important contributions to our current understanding of the mechanisms that shape cells into different tissues during morphogenesis. Recent advances in high‐resolution and live‐cell‐imaging techniques provided new insights into the social behavior of cells based on careful visual observations within the context of a living tissue. In this review, (...) we will compare Drosophila testis nascent myotube migration with established in vivo model systems, elucidate similarities, new features and principles in collective cell migration.

Une lecture de l'oeuvre pascalienne à la lumière de notions créées par des philosophes contemporains, montrant comment la pensée de Pascal peut accompagner la réflexion audelà du contexte du XVIIe siècle.

The conceptual axis of this paper is a reflection on Charles Peirce’s realism, trying to show it as the ground from which many others of his philosophical doctrines are derived. In its first part, the paper analyses the problems posed by the classical Peircean paper Questions Concerning Certain Faculties Claimed for Man, proposing to extract from the consequences of this analysis the guidelines of a realism that gradually become more radical in Peirce’s mature work. Such consequences will be consolidated in (...) his Phenomenology, a science that will ground Semiotics and a conception of symmetry related to Peirce’s categories. This symmetry regarding his epistemology and ontology will be, by the way, omnipresent in all Peircean philosophical system. The second part of the paper discusses the concepts of mediation and representation, also under a realistic background, concluding that these concepts cannot be coherently interlaced in nominalistic philosophies, in which is often found theoretical consequences somehow committed with dogmatic and no dialogic postures, in the sense of a meaning analysis proposed by the classical Peircean pragmatism.

In this paper we examine two approaches to the formal treatment of the notion of problem in the paradigm of algorithmic semantics. Namely, we will explore an approach based on Martin-Löf’s Constructive Type Theory, which can be seen as a direct continuation of Kolmogorov’s original calculus of problems, and an approach utilizing Tichý’s Transparent Intensional Logic, which can be viewed as a non-constructive attempt of interpreting Kolmogorov’s logic of problems. In the last section we propose Kolmogorov and CTT-inspired modifications to (...) TIL-based approach. The focus will be on non-empirical problems only. (shrink)

Is there a poetic ground in Peirce's philosophy? While this question may sound interesting, it is somehow odd, as Peirce is well–known as a logician, and it is also known by scholars that he was not an expert in poetry, literature, art, or even theories concerning art in general. This paper hypothesizes that there is a starting point in his philosophy that is poetical in its nature. Moreover, Peirce's system is obviously logical in its form, but also keeps the spirit (...) of the original silent feeling of poetry that seems to have fascinated him. Also, I claim there is a Schellingian heritage in Peirce's philosophy that is partially responsible for that poetic starting point. This idea also has, as a support, the supposition that a realistic view of the world provides a hypothesis of symmetry between the human and natural worlds, which provides the basic form for his ontological theories and for the theoretical harmony among Peirce's doctrines. This quality of Peirce's philosophy is a kind of a Greek beauty that is only evident for those who can view his thought not in fragments but as a complex system that has the potency of not only answering classical philosophical questions, but also of giving rise to a new philosophy which needs to be further developed.

In this paper, we will be interested in the notion of a computable proposition. It allows for feasible computational semantics of empirical sentences, despite the fact that it is in general impossible to get to the truth value of a sentence through a series of effective computational steps. Specifically, we will investigate two approaches to the notion of a computable proposition based on constructive type theory and transparent intensional logic. As we will see, the key difference between them is their (...) accounts of denotations of empirical sentences. (shrink)

Proofs from assumptions are amongst the most fundamental reasoning techniques. Yet the precise nature of assumptions is still an open topic. One of the most prominent conceptions is the placeholder view of assumptions generally associated with natural deduction for intuitionistic propositional logic. It views assumptions essentially as holes in proofs, either to be filled with closed proofs of the corresponding propositions via substitution or withdrawn as a side effect of some rule, thus in effect making them an auxiliary notion subservient (...) to proper propositions. The Curry–Howard correspondence is typically viewed as a formal counterpart of this conception. I will argue against this position and show that even though the Curry–Howard correspondence typically accommodates the placeholder view of assumptions, it is rather a matter of choice, not a necessity, and that another more assumption-friendly view can be adopted.

The main objective of this paper is to sketch unifying conceptual and formal framework for inference that is able to explain various proof techniques without implicitly changing the underlying notion of inference rules. We base this framework upon the so-called two-dimensional, i.e., deduction to deduction, account of inference introduced by Tichý in his seminal work The Foundation’s of Frege’s Logic (1988). Consequently, it will be argued that sequent calculus provides suitable basis for such general concept of inference and therefore should (...) not be seen just as technical tool, but philosophically well-founded system that can rival natural deduction in terms of its “naturalness”.

Comment et pourquoi affirmer que l'humanisme d'un penseur catholique du XVIIe siècle peut nous guider dans la compréhension de phénomènes culturels contemporains, c'est in fine la question qui commande cette étude rigoureuse et audacieuse. Faire dialoguer de façon féconde le projet de Blaise Pascal et la pop culture, appréhendée à partir des tribus musicales punk, rock, skinhead, gothique, hip-hop et électro, c'est l'objectif du travail de Jean-Louis Bischoff.

In this paper, we consider the ex falso quodlibet rule (EFQ) as a derived rule and propose a new justification for it based on a rule we call the collapse rule. The collapse rule is a mix between EFQ and disjunctive syllogism (DS). Informally, it says that a choice between a proposition A and ⊥, which is understood as nullary disjunction, is no choice at all and it defaults to A. Thus, we can regard it as capturing the idea of (...) an implosion principle in contrast to EFQ’s explosion principle. Furthermore, we show that the collapse rule can also be used to justify DS and that all these three rules have the same deductive strength: they are all interderivable. Thus, the discussions about the justification of EFQ or DS be reduced to a discussion about the justification of the collapse rule. (shrink)

Following the theory of Boolean algebras with modal operators , in this paper we investigate Boolean algebras with sufficiency operators and mixed operators . We present results concerning representability, generation by finite members, first order axiomatisability, possession of a discriminator term etc. We generalise the classes BAO, SUA, and MIA to classes of algebras with the families of relative operators. We present examples of the discussed classes of algebras that arise in connection with reasoning with incomplete information.
