Es wird gezeigt, daß in der Skizze zum Beweis des 2. Satzes von Gödel dieser eine stillschweigende Voraussetzung macht, die im Widerspruch zu den üblichen Forderungen nach Eindeutigkeit der benutzten Terme steht: Eine und dieselbe Gödelzahl g repräsentiert nämlich einmal den Ausdruck g1: "ein im System k unentscheidbarer Satz" und das andere Mal den Ausdruck g2: "g1 ist in k nicht beweisbar". Beachtet man aber diesen Unterschied, so ist der Widerspruch nicht herleitbar, auf dem der Gödelsche Beweis basiert.

At Columbia University in 1906, William James gave a highly confrontational speech to the American Philosophical Association (APA). He ignored the technical philosophical questions the audience had gathered to discuss and instead addressed the topic of human energy. Tramping on the rules of academic decorum, James invoked the work of amateurs, read testimonials on the benefits of yoga and alcohol, and concluded by urging his listeners to take up this psychological and physiological problem. What was the goal of this unusual (...) speech? Rather than an oddity, Francesca Bordogna asserts that the APA address was emblematic—it was just one of many gestures that James employed as he plowed through the barriers between academic, popular, and pseudoscience, as well as the newly emergent borders between the study of philosophy, psychology, and the “science of man.” Bordogna reveals that James’s trespassing of boundaries was an essential element of a broader intellectual and social project. By crisscrossing divides, she argues, James imagined a new social configuration of knowledge, a better society, and a new vision of the human self. As the academy moves toward an increasingly interdisciplinary future, William James at the Boundaries reintroduces readers to a seminal influence on the way knowledge is pursued. (shrink)

Farmers’ markets (FMs) represent a crucial player in urban food systems, being the interconnection of local agricultural production and consumption, and serving as spaces for both economic exchange and community building. Despite their transformative potential, there is a scarcity of research that comprehensively investigates the dynamics of FMs network structure and the influence of the actors shaping FMs. The present article delves into the network of relationships within FMs in the Italian city of Bologna. This study adopts the Social Network (...) Analysis (SNA) methodology applied with the Net-Map tool. The research objectives are to visualise the underlying network structure, map the dynamics, and identify the key actors who play pivotal roles in Bologna’s FMs and their level of influence. The research carried out interviews with ten FMs stakeholders, revealing the network of relationships between 54 actors, divided into three categories—civil society, food economy and public administration. Actors were linked by a total of 428 relationships across three types of networks: support, economic, and hindering. Findings indicate a strong support network structure characterised by varying degrees of centrality among different actors. Farmers emerge as a central node due to their pivotal role in providing fresh, local produce. Additionally, local institutions contribute significantly to FMs resilience and growth. Our research demonstrates the importance of recognising the embeddedness of FMs within the local context. By understanding the network structure and influential actors in FMs, policymakers can devise more effective policies for promoting local agriculture, and enhancing the sustainability of urban–rural exchanges. In conclusion, the present study offers valuable insights into the network dynamics of FMs, highlighting their crucial role in the sustainable development of urban and local food systems. (shrink)

In health communication, metaphor can be considered as a reasoning device to let people understand an abstract concept in terms of a concrete one (Lakoff and Johnson 1980; Bowdle and Gentner 2005). Both the positive and negative communicative effects of metaphors have been largely pointed out in a variety of medical fields, from oncology (Semino et al. 2016, 2018) to mental health (Frezza and Zoccolotti 2019). The use of metaphors in vaccine communication has been less considered, though it might be (...) crucial to let people understand vaccination as an important collective health phenomenon. A previous study (Scherer et al. 2015) focused on the communicative effects of conventional metaphors for vaccination, but not specifically on novel metaphors deliberately used to explain the concept of population immunity in vaccination. We hypothesized that metaphors used to explain vaccination as a collective phenomenon could improve the communicative aims of pro-vaccination texts in many respects, ranging from understandability to trust in expertise. We designed a study to test the hypothesis: two groups of participants were presented with a text about vaccination as a collective phenomenon, described in either literal or metaphorical terms. They were asked to evaluate the text on different communicative aspects from both an individual and a collective point of view. The results confirmed the hypothesis that metaphor is an effective reasoning device and that it also enhances the overall communicative effects of the message, in terms of understandability, persuasion, feeling of control over the health situation, trust in expertise, and uptake of experts’ advice. However, the results show that this effect is significantly nuanced in the individual vs. collective response type. (shrink)

An inquiry drawing on the presence of Hellenistic philosophy in Philo provides a better knowledge of the diffusion of Hellenistic philosophy since the late ...

The topic tackled in this book is Philo's account of the complex, double-sided nature of God's acting - the two-sided coin of God as transcendent yet immanent, ...

This paper studies internal (or intra-)mathematical explanations, namely those proofs of mathematical theorems that seem to explain the theorem they prove. The goal of the paper is a rigorous analysis of these explanations. This will be done in two steps. First, we will show how to move from informal proofs of mathematical theorems to a formal presentation that involves proof trees, together with a decomposition of their elements; secondly we will show that those mathematical proofs that are regarded as having (...) explanatory power all display an increase of conceptual complexity from the assumptions to the conclusion.

Through this contribution I aim to explore the horizons and limits of digital medicine in light of an embodied approach to the issue of care. I will sketch the historical background of digital medicine and show the contemporary status of this interdisciplinary field, as well as its applications and outcomes. Then, I will address a critique of the computational theory of mind (CTM) upon which many contemporary mental health apps are designed. This approach to the mind is inscribed into the (...) modern trend of neuromania, which conceives the embodied, living human being as a mere series of data analyses and algorithms, with the brain as the seat of the person. Drawing on continental philosophy and classical phenomenology I will develop a notion of health conceived as a moral enterprise, showing how wellbeing and vitality are not reducible to a product made by technologies or doctors, but rather they are the results of an embodied encounter. As such, empathy and person-centered care cannot be achieved by digital medicine. They are the result of a journey into the regions of recognition, embodied presence and the aliveness constituting the person. Finally, I will show how the issue of care cannot be separated from an embodied encounter between people, especially in case of dementia. (shrink)
