In everyday reasoning - just as in science and art - knowledge is acquired more by "doing" than with long analyses. What do we "do" when we discover something new? How can we define and explore the pattern of this reasoning, traditionally called "synthetic"? Following in the steps of classic pragmatists, especially C.S. Pierce, Giovanni Maddalena's Philosophy of Gesture revolutionizes the pattern of synthesis through the ideas of change and continuity and proposes "gesture" as a new tool for synthesis. (...) Defining gesture as an action with a beginning and an end that carries on a meaning, Maddalena explains that it is a dense blending of all kinds of phenomena - feelings and vague ideas, actual actions, habits of actions - and of signs - icons, indexes, and symbols. When the blending of phenomena and signs is densest, the gesture is "complete," and its power of introducing something new in knowledge is at its highest level. Examples of complete gestures are religious liturgies, public and private rites, public and private actions that establish an identity, artistic performances, and hypothesizing experiments. A departure from a traditional Kantian framework for understanding the nature and function of reason, The Philosophy of Gesture proposes an approach that is more attuned with our ordinary way of reasoning and of apprehending new knowledge.

Proprioception is a crucial sensory modality involved in the control and regulation of coordinated movements and in motor learning. However, the extent to which proprioceptive acuity is influenced by local muscle fatigue is obscured by methodological differences in proprioceptive and fatiguing protocols. In this study, we used high resolution kinematic measurements provided by a robotic device, as well as both frequency and time domain analysis of signals captured via surface electromyography (sEMG) to examine the effects of local muscle fatigue on (...) wrist proprioceptive acuity in 16 physically and neurologically healthy young adults. To this end, participants performed a flexion/extension ipsilateral joint position matching test (JPM), after which a high-resistive robotic task was used to induce muscle fatigue of the flexor carpi radialis (FCR) muscle. The JPM test was then repeated in order to analyze potential changes in proprioceptive acuity. Results indicated that the fatigue protocol had a significant effect on movements performed in flexion direction, with participants exhibiting a tendency to undershoot the target before the fatigue protocol (-1.218°), but overshooting after the fatigue protocol (0.587°). In contrast, in the extension direction error bias values were similar before and after the fatigue protocol as expected (pre = -1.852°, post = -1.237°) and reflected a tendency to undershoot the target. Moreover, statistical analysis indicated that movement variability was not influenced by the fatigue protocol or movement direction. In sum, results of the present study demonstrate that an individual’s estimation of wrist joint displacement (i.e., error bias), but not precision (i.e., variability), is affected by muscular fatigue in a sample of neurologically and physically healthy adults.

Medical imaging is predominantly a visual field. In this context, prenatal ultrasound images assume intense social, ethical, and psychological significance by virtue of the subject they represent: the fetus. This feature, along with the sophistication introduced by three-dimensional ultrasound imaging that allows improved visualization of the fetus, has contributed to the common impression that prenatal ultrasound scans are like photographs of the fetus. In this article we discuss the consistency of such a comparison. First, we investigate the epistemic role of (...) both analogic and digital photographic images as visual information-providing representations holding a high degree of objectivity. Second, we examine the structure and process of production of ultrasound scans and argue that a comparison between two-dimensional ultrasound and photography is justified. This is in contrast to 3D ultrasound images that, due to the intensive mathematical processing involved in their production, present some structural issues that obfuscate their ontological and epistemic status.

According to the standard interpretation, Italian pragmatism is split into two groups. On the one hand is the mathematician Giovanni Vailati, Peano’s former collaborator, and his disciple, the economist Mario Calderoni. On the other hand, there are the two “brats,” Giovanni Papini and Giuseppe Prezzolini, naïve philosophers with eccentric ideas. While Vailati and Calderoni followed Peirce’s mathematical and logical pragmatism, the other two articulated a “magical” pragmatism, a kind of relativist, post-modern version of the original American movement. The paper shows (...) that this narrative is incomplete. During the years 1905-6, while Vailati was living in Florence, Italian pragmatists listed three kinds of pragmatism among themselves. Relying on the third stripe, attributed to Vailati, they found a more Unitarian, theoretical project that united the will to belief and the precision of reasoning. The unity did not last very long because Vailati moved from Florence in 1906. However, the common project from 1905-6 remains the highest peak of their awareness of pragmatism and, possibly, an original way to interpret it. (shrink)

There exist two notions of equivalence of behavior between states of a Labelled Markov Process (LMP): state bisimilarity and event bisimilarity. The first one can be considered as an appropriate generalization to continuous spaces of Larsen and Skou’s probabilistic bisimilarity, whereas the second one is characterized by a natural logic. C. Zhou expressed state bisimilarity as the greatest fixed point of an operator that there is such a process with an uncountable Zhou ordinal.

Porphyry’s Expositio per interrogationem et responsionem can help us to understand some obscure passages of chapter seven of Aristotle’s Categories, focused on the relative. The Porphyrian analysis of πρός τι presents indeed developments which are both useful for the understanding of the Aristotelian text and very innovative too. First, we can mention the general Porphyrian thesis according to which categories are predicates. This theory fits very well with πρός τι, which are predicates corresponding to properties that subjects only possess because (...) of an observed reciprocal relationship. This brings us to the second novelty of Porphyry’s analysis, really important for modern developments of the notion of relation, namely the difference between σχέσις and πρός τι, which depends on it. Finally, we will mention the important Porphyry’s contribution to the understanding of a particularly obscure issue concerning the relationship between the two definitions of πρός τι that Aristotle provides. Porphyry points out the Platonic origin of the first definition, without dismissing it though: instead, he will just consider it too vast and encompassing the true πρός τι, object of the second definition.

Peirce did not achieve a final systematization of his work. Beyond the difficulties in explaining so many philosophical tools that he introduced—suffice it to mention semiotic, abductive logic, a heuristic based on continuity, scholastic realism—, there is a theoretical reason for this incompletion. All those new philosophical tools indicated a conception of synthesis very different from the one he received from Kant. Peirce did not realize the profound direction of his enquiry so that he did not directly question neither Kant’s (...) legacy on this issue nor the idea of necessity that presides over it. Starting from Peirce’s conception of continuity and change, this paper will give a new definition of synthetic and analytic judgments and reasoning, completing the picture with a third “vague” judgment and reasoning. In this new definition a synthetic judgment is a judgment that recognizes identity through changes. An analytical judgment is a judgment that loses identity through changes. A vague judgment is a judgment that it is blind to identity through changes. How do we perform synthetic reasoning? Following Peirce’s semiotic study of elements of Gamma Graphs as the sheet of assertion and the line of identity, the paper will first individuate the semiotic characteristics necessary for the recognition of identity. These characteristics lead us to discover “complete gesture” as the tool that we use in our every-day reasoning in order to acquire new knowledge synthetically. “Complete gestures” are actions through which we carry and recognize significant meanings. This new paradigm should provide an improved account of common-sense knowledge as well as of particular creative and hypothetic stages of conception in both scientific and humanistic thought.

In this paper I shall try to give you a good reason for sharing with Peirce his doubts on Pragmatism. What I am going to maintain is that Peirce found in his Semeiotic, through which he was looking for a real “proof” for pragmatism, hints, vanishing points that made him think that pragmatism was just a part of a richer logical realm and of a far richer reality. What he doubted was not pragmatism in itself but that it could comprehend (...) the whole realm of logic. The key of the point that I want to make is the famous “rational instinct”, but in order to understand its role and function I have to go through some clues that it is possible to find in the first branch of semeiotics and then to confirm my analysis with a brief reference to Methodeutics. In the end I will suggest that these reasons, which urged Peirce to increase the importance of the rational instinct, are the same that lie beneath his latest and worse known ideas on continuity and infinity. It is well known that in his late years Peirce was dealing with many things: he was writing “The Amazing Mazes of Mathematics”, he was trying to develop his theory of continuity and he was trying to re-publish his papers on Pragmatism with some correction. In the confused manuscripts of this last period of his life you can find, whatever was the topic he was talking about, questions on which he kept pondering again and again. In doing this kind of analysis Peirce often stated points that do not have a precise development or that cannot find a precise collocation in his synthetic statements. Therefore, what I am going to do is to underline these points and then to try drawing a conclusion that can account for them. The only problem of this task is due to the unavoidable brevity of a paper so that my discourse will probably look more a chain not stronger that is its weakest link than a cable whose every fiber helps the strength of the whole.

O presente trabalho está voltado à investigação epistemológica acerca da relação entre Self não conceitual, conteúdo não conceitual da percepção, prontidão para ação e reconhecimento de lugar, no contexto da perspectiva ecológica gibsoniana. Tendo em vista este propósito investigativo, nossos objetivos são: 1- caracterizar o conteúdo não conceitual da percepção no contexto anti-representacionista e 2 - questionar se é necessário a consciência para os organismos agirem no ambiente e adquirirem experiências perceptivas como o reconhecimento de lugar. Argumentaremos em defesa da (...) hipótese de que a teoria ecológico-informacional e anti-representacionista da percepção, com raízes gibsonianas, oferece subsídios teóricos inovadores para a análise do nosso propósito investigativo. Entendemos que para ter consciência e capacidade de pensar sobre si mesmo, o agente tem que, primeiramente, ter experiências perceptivas básicas do ambiente. Consideramos que essas experiências perceptivas básicas do agente, como o reconhecimento de lugar, não envolvem necessariamente a consciência. (shrink)

Derrida’s reading of Heidegger’s 1962 lecture On Time and Being concludes the last session of the 1978–79 seminar published in Donner le temp II. There, Heidegger suggests that the task of thinking consists of thinking Being without regard to metaphysics, while ceasing all overcoming of metaphysics as such. What is given as the task for thought is that which onto-theology makes impossible to think, that is, the constitutive aporetic remainder of metaphysical thinking. This essay contends that for both Heidegger and (...) Derrida the task of thought consists in this same matter of thinking, with which the question of the gift primarily deals. It maintains that in order to think the giving of the gift without regard to metaphysics, the gift could be thought in terms of anxiety. In this perspective, anxiety emerges as a thoughtful affect that gives an access to thinking the impossible, cutting through the onto-theological order of metaphysics. Finally, bringing together Heidegger and Lacan’s accounts of anxiety allows us to creep deeper into this liminal dimension of what is to be thought. (shrink)

The physical, psychological, and spiritual violence against fat bodies in the US, committed in service of a racist, sexist, classist, and ableist vision of an idealized body size, is death-dealing. This essay develops a theo-ethical vision of fat liberation that rejects the trappings of the “religion of thinness” and celebrates the inherent worth of fat bodies through an incarnational theology that recognizes the image of God in every body size, the presence of body size diversity in creation, and the full (...) inclusion of all body sizes at the eucharistic table.

Decision-making under uncertainty is sometimes investigated as a homogeneous problem, independently of the type of decision-maker and the level and nature of the decision itself. However, when the decision-maker is a public authority, there immediately arise problems additional to those that concern any other (private) decision-maker. This is not always clearly recognised in orthodox discussions on decisions under conditions of uncertainty. This article investigates the methodological, strategic and procedural challenges of taking public decisions in such conditions. It focuses mainly on (...) decisions involving urban contexts, such as planning decisions regarding land use and building transformations, by trying to develop some pioneering research studies in this field.

Este breve texto esboça algumas ideias básicas da Filosofia Ecológica, enfatizando a importância e o valor de tais idéias para o estudo da mente e da consciência. Estas considerações levam à formação de uma abordagem ecológica, e o que, aqui, denomino Filosofia Ecológica. Em particular, a Filosofia Ecológica oferece uma saída às confusões e contradições que são comuns ao pensamento acadêmico dominante no que se refere à mente e à consciência.

Gava's book is worth reading. It is one of the best accounts of the attempt to read Peirce within a transcendental model of philosophy. This position is now one of the most powerful in Peirce's scholarship, even though it is highly problematic from both an exegetical and a theoretical standpoint. I will try to explain these problems at the end of this review, but first I will sketch Gava's detour and some positive advancements in Peirce's scholarship that he accomplishes.Gava's way (...) to link Peirce to transcendental philosophy is based on a general reading of the development of Peirce's thought. In this reading, Peirce would have been very Hegelian in his early writings where he strongly linked "being"... (shrink)

This paper is a contribution to the study of the four classical Italian pragmatists: Papini, Prezzolini, Vailati and Calderoni. They are seen more as representatives of a pragmatist movement than as singular systematic thinkers. The center of Italian pragmatism was the periodical, Leonardo, where these authors discussed and presented an original and provocative understanding of pragmatist philosophy. Thier understanding of pragmatist philosophy has often been underestimated by the subsequent literature. They showed a good comprehension of the novelty brought by American (...) pragmatism but, ignoring some of the most important epistemic aspects of Peirce’s and James’s theories, their philosophical proposals often missed consistency. However, even in their misunderstandings, they signaled a need and possibly a weakness of the whole pragmatist movement. Italian pragmatists underlined the importance of the concreteness of individuals in the realization of universal laws of mathematics and logic, physics and psychology. But, this attitude suffered from some serious tensions between metaphysical assumptions and methodological claims. (shrink)

The Covid-19 pandemic has been analysed and discussed from many disciplinary perspectives. An aspect that still needs critical exploration is the role—that is, the modes and forms—of regulatory interventions during the pan- demic. It is interesting to note in this regard that, in many studies, regulatory measures are labelled “non-pharma- ceutical interventions”, as if they do not have any specificity on their own and only represent a theoretically residual category. The main aim of this article is instead to focus on (...) the distinctive features of normative measures as such. As regards the article’s focus, it centres on the normative interventions in the first period of the pandemic—that is, 2020—with particular reference to Italy. We have chosen to focus on this period because the most extensive and severe restrictions introduced to combat Covid-19 were established at that time. And we have chosen to con- sider Italy because it was the first country, after China, to be hard hit by the virus and to react in a draconian manner. As regards the methodology, the article is based, in general and primarily, on an extensive interdisciplinary literature review. With reference to the Italian case, the study is additionally based on: first-hand data collection and analysis (especially concerning Italian normative measures mainly issued at the national level: their type, frequency, target, hierarchical relationships); second-hand data and analysis (for instance as regards the effectiveness of Italy’s and other countries’ regulatory measures). In discussing the Italian response to the Covid-19 pandemic, certain weaknesses have been identified; and possible lessons have been highlighted, in terms of both “planning” (i.e. the necessity to better pre-define concrete and circumscribed sets of actions) and of “meta-planning” (i.e. the necessity of better planning the way in which public authorities could and should plan and act). Although this article is mainly based on the Italian situation, what we can learn from this case is largely generalizable. (shrink)

We study a contemporary need to complement analytic philosophy with pendular, synthetic approaches. We provide new definitions of the dyad analytics/synthetics and complete it with a natural third, horotics. Some historical trends to support a synthetic/horotic paradigm are studied: (i) Peirce’s ideas around his logic of continuity – non Cantorian continuum and existential graphs – emphasizing the importance of mathematical gestures, (ii) Gödel’s understanding of intuitionism as a synthetic counterpart of classical logic, along with a new horotic approach to his (...) work, (iii) Contemporary mathematical achievements (1950-2000), difficult to understand from analytical philosophy perspectives. Finally, we indicate some main features that a systematical synthetic/horotic reasoning should enforce, in order to fulfill its historic sequence. (shrink)

A Teoria dos Dois Sistemas, proposta por Kahneman (2011), pressupõe que a tomada de decisão no contexto econômico se baseia em dois sistemas, um que é automático, intuitivo e principalmente inconsciente e outro reflexivo, racional e totalmente consciente. Consideramos a abordagem kahnemaniana incompleta na medida em que a concepção dos sistemas 1 e 2 não é suficiente para explicar os processos de tomada de decisão. Neste artigo, nosso desafio é mostrar que, diferentemente dos sistemas de Kahneman, a tomada de decisão (...) está ancorada na percepção direta de affordances e é a base das escolhas conceituais, que envolvem experiências sensório-motoras advindas da reciprocidade entre agente e ambiente. Concluímos este artigo, argumentando que, diferentemente da concepção de sistema 1 kahnemaniano, na perspectiva ecológica, a tomada de decisão advém de experiências não conceituais, da percepção direta, não automática, sem envolver representações mentais e processamento de informações.

Since the middle of the last century, normative language has been much studied. In particular, the normative function performed by certain sentences and by certain speech acts has been investigated in depth. Still, the normative function performed by certain physical artifacts designed and built to regulate human behaviors has not yet been thoroughly investigated. We propose to call this specific type of artifacts with normative intent ‘deontic artifacts’. This article aims to investigate this normative phenomenon that is so widespread in (...) our daily reality, but so often forgotten by scholars of norms and normativity. (shrink)

Il percorso di Rosa Calcaterra all’interno della filosofia pragmatista è segnato da un’intuizione principale e originale: nonostante tutte le differenze, il progetto pragmatista è unitario. Gli articoli della raccolta Il progetto comune dei pragmatisti mostrano questa unitarietà, che Calcaterra persegue con tecnica sofisticata, facendo emergere non solo ciò che la parola dice, ma anche ciò che essa tradisce.

It is difficult to devise a new approach to any topic in Peirce scholarship, and it is also difficult to convincingly bring one to life. Tullio Viola's book, Peirce on the Uses of History, elegantly accomplishes this second trick, making it well worth reading.

We analyze the role of ethical values in the determination of the social cost of carbon, arguing that the familiar debate about discounting is too narrow. Other ethical issues are equally important to computing the social cost of carbon, and we highlight inequality, risk, and population ethics. Although the usual approach, in the economics of cost-benefit analysis for climate policy, is confined to a utilitarian axiology, the methodology of the social cost of carbon is rather flexible and can be expanded (...) to a broader set of social-welfare approaches.

The paper will focus on Rorty’s project as it emerges in the compelling introductions to his books from Philosophy and the Mirror of Nature onwards. Even disagreeing with his conclusions, some interesting items suggest that Rorty was a legitimate member of the pragmatist family and that he shared with classic pragmatists much more than a reader can see at first glance. First, Rorty understood better than anyone else that the fight against Kant’s rationalism is crucial to pragmatism considered as a (...) whole. He paralleled Kantism with the history of explaining knowledge as a mirroring representation and he wanted to get rid of it. Second, Rorty shared with classic pragmatists what I call the “synthetic drive” of philosophy, namely, the view of philosophy as the habit of action of looking at anything in a way that makes it “hang together with everything else.” Third, the outcome of the synthetic drive is conceiving philosophy as a transformative activity. In all these cases, Rorty took roads at odds with classic pragmatism but he did not betray the general aim and spirit of the American movement of thought. (shrink)

This book addresses the social, functional and symbolic dimensions of urban space in today’s world. The twelve essays range from a conceptual framing of the issues to case descriptions, rich with illustrations. Together they provide a thorough exploration of the nature and significance of social space and particular aspects of its distribution in today’s urban spaces and the various factors that are competing for it. -/- The book addresses a topic that is intrinsically interdisciplinary. Questions of space are examined from (...) a rich variety of perspectives from urban planning to political philosophy, shedding some light on this shadowy process. Some of the issues addressed include the dichotomies of public and private space, rights and duties regarding the use of space, and conflicts over its allocation. Well-reasoned and lively discussions are offered from the perspective of basic values and rights. The recognition of the specifics of (minority community) identity as an institutional policy is raised in opposition to “abstract distributive accounts of justice” – economic pressures by developers and would-be gentrifiers.
