The purpose of this essay is to study the extent in which the semantics for different logical systems can be represented game theoretically. I will begin by considering different definitions of what it means to gamify a semantics, and show completeness and limitative results. In particular, I will argue that under a proper definition of gamification, all finitely algebraizable logics can be gamified, as well as some infinitely algebraizable ones (like Łukasiewicz) and some non-algebraizable (like intuitionistic and van Fraassen supervaluation (...) logic).

This paper focuses on radical pooling, or the question of how to aggregate credences when there is a fundamental disagreement about which is the relevant logical space for inquiry. The solution advanced is based on the notion of consensus as common ground, where agents can find it by suspending judgment on logical possibilities. This is exemplified with cases of scientific revolution. On a formal level, the proposal uses algebraic joins and imprecise probabilities; which is shown to be compatible with the (...) principles of marginalization, rigidity, reverse bayesianism, and minimum divergence commonly endorsed in these contexts. Furthermore, I extend results from previous work by to show that pooling sets of imprecise probabilities can satisfy important pooling axioms. (shrink)

The question of how the probabilistic opinions of different individuals should be aggregated to form a group opinion is controversial. But one assumption seems to be pretty much common ground: for a group of Bayesians, the representation of group opinion should itself be a unique probability distribution, 410–414, [45]; Bordley Management Science, 28, 1137–1148, [5]; Genest et al. The Annals of Statistics, 487–501, [21]; Genest and Zidek Statistical Science, 114–135, [23]; Mongin Journal of Economic Theory, 66, 313–351, [46]; Clemen and (...) Winkler Risk Analysis, 19, 187–203, [7]; Dietrich and List [14]; Herzberg Theory and Decision, 1–19, [28]). We argue that this assumption is not always in order. We show how to extend the canonical mathematical framework for pooling to cover pooling with imprecise probabilities by employing set-valued pooling functions and generalizing common pooling axioms accordingly. As a proof of concept, we then show that one IP construction satisfies a number of central pooling axioms that are not jointly satisfied by any of the standard pooling recipes on pain of triviality. Following Levi, 3–11, [39]), we also argue that IP models admit of a much better philosophical motivation as a model of rational consensus. (shrink)

We explore which types of probabilistic updating commute with convex IP pooling. Positive results are stated for Bayesian conditionalization, imaging, and a certain parameterization of Jeffrey conditioning. This last observation is obtained with the help of a slight generalization of a characterization of externally Bayesian pooling operators due to Wagner :336–345, 2009). These results strengthen the case that pooling should go by imprecise probabilities since no precise pooling method is as versatile.

Trust in vaccination is eroding, and attitudes about vaccination have become more polarized. This is an observational study of Twitter analyzing the impact that COVID-19 had on vaccine discourse. We identify the actors, the language they use, how their language changed, and what can explain this change. First, we find that authors cluster into several large, interpretable groups, and that the discourse was greatly affected by American partisan politics. Over the course of our study, both Republicans and Democrats entered the (...) vaccine conversation in large numbers, forming coalitions with Antivaxxers and public health organizations, respectively. After the pandemic was officially declared, the interactions between these groups increased. Second, we show that the moral and non-moral language used by the various communities converged in interesting and informative ways. Finally, vector autoregression analysis indicates that differential responses to public health measures are likely part of what drove this convergence. Taken together, our results suggest that polarization around vaccination discourse in the context of COVID-19 was ultimately driven by a trust-first dynamic of political engagement. (shrink)

I will argue that Roy Cook’s (forthcoming) reformulation of Yablo’s Paradox in the infinitary system D is a genuinely non-circular paradox, but for different reasons than the ones he sustained. In fact, the first part of the job will be to show that his argument regarding the absence of fixed points in the construction is insufficient to prove the noncircularity of it; at much it proves its non-self referentiality. The second is to reconsider the structural collapse approach Cook rejects, and (...) argue that a correct understanding of it leads us to the claim that the infinitary paradox is actually non-circular. En este trabajo argumentaré que la reformulación que Roy Cook (forthcoming) hace de la paradoja de yablo en el sistema infinitario D es una genuina paradoja no circular, pero por motivos distintos a los defendidos por ese autor. La primera parte del trabajo consiste en mostrar que la ausencia de puntos fijos en la construcción es insuficiente para demostrar su no circularidad, a lo sumo prueba su no autorreferencialidad. La segunda parte consiste en volver a considerar el enfoque del colapso estructural que Cook rechaza, y argumentar que una correcta comprensión del mismo revela que la paradoja es genuinamente no circular.

The social media platform Twitter platform has played a crucial role in the Black Lives Matter (BLM) movement. The immediate, flexible nature of tweets plays a crucial role both in spreading information about the movement’s aims and in organizing individual protests. Twitter has also played an important role in the right-wing reaction to BLM, providing a means to reframe and recontextualize activists’ claims in a more sinister light. The ability to bring about social change depends on the balance of these (...) two forces, and in particular which side can capture and maintain sustained attention. The present study examines 2 years worth of tweets about BLM (about 118 million in total). Timeseries analysis reveals that activists are better at mobilizing rapid attention, whereas right-wing accounts show a pattern of moderate but more sustained activity driven by reaction to political opponents. Topic modeling reveals differences in how different political groups talk about BLM. Most notably, the murder of George Floyd appears to have solidified a right-wing counter-framing of protests as arising from dangerous “terrorist” actors. The study thus sheds light on the complex network and rhetorical effects that drive the struggle for online attention to the BLM movement. (shrink)

Epidemiological models directly shape policy responses to public health crises. We argue that they also play a less obvious but important role in solving certain coordination problems and social dilemmas that arise during pandemics. This role is both ethically and epistemically valuable. However, it also gives rise to an underappreciated dilemma, as the features that make models good at solving coordination problems are often at odds with the features that make for a good scientific model. We examine and develop this (...) dilemma in the context of the COVID-19 pandemic, and suggest extensions to other domains. (shrink)

According to some Foucault' proposals, this paper deals with the historical constitution of individual identity forms through juridic practices, concretely the results of the transformation of modern law from the state monopo-lization of the legislative functions, a process considered to be based on so-cial contract theories -the constitution of social order according to a successive scheme: from the pre-social individuals to supra-individual society. The juridical individualism derives from this model, and the critical ap-proach on it is made from the contemporary (...) sciences of human behavior. (shrink)

I wish to express, first of all, my profound gratitude to Professor J. M. Bochenski, without whose assistance the present work would have not been possible. To be concise, I would like to state that his contribution to this book may be viewed at three levels: (1) that of the general spirit, (2) that of the specific ideas, theses or approaches which are expressed in its pages, (3) that of this work qua doctoral dissertation. The general spirit which has guided (...) my research coincides with that underlying Professor :Oochenski's own works, in particular his Formale Logik (Munchen 1956). Moreover, the particular occasion which suggested my investigation was a statement included in that book according to which the literature in the field still lacked a detailed work on Frege (p. 317). I wish, likewise, to express my gratitude to other professors of the University of Fribourg for their generous help. I mention especially Professors P. Wyser, M. D. Philippe, N. Luyten, and V. Kuiper. I have also benefited from Professor E. Specker's lectures at the Eidge nossische Technische Hochschule (ZUrich) and from Professor Olof Gigon's lectures at the University of Bern. From an earlier period I wish to express my gratitude to the professors of the philosophy department of the Universidad Nacional de Buenos Aires, especially the late Professor Francisco Romero. The Swiss National Library (Bern) has greatly facilitated access to bibliographical sources, and the library of the University of Munster (Westphalien) has kindly provided microfilms of Frege's Nachlap.

El problema de la libertad es uno de los más áridos de la filosofía. Paul Ricoeur intenta reconstruir el problema tomando el eje del análisis: la naturaleza dicotómica de los discursos sostenidos sobre la cuestión. De un lado, tenemos la “perspectiva de la tercera persona”. Desde esta mirada, cada acto que realizamos está causalmente determinada. Por el otro lado, tenemos la “perspectiva de la tercera persona”, en la que todas nuestras acciones libres parecieran brotar del “yo”. El problema comienza cuando (...) intentamos reconciliar ambas perspectivas. Este trabajo revisará algunos de los argumentos presentados por ambos lados, y el posicionamiento de Ricoeur en el debate.

En este breve comentario discuto algunos aspectos de la interpretación de la epistemología de Davidson que sugiere Willian Duica en su reciente libro. Luego de una presentación somera del libro me centro en tres asuntos centrales de la interpretación de Duica. En primer lugar, argumento que su lectura de la crítica de Davidson al dualismo esquema/contenido es muy restrictiva y deja abierta la posibilidad de un realismo directo empirista. En segundo lugar, argumento que en su lectura el propio Duica se (...) compromete inadvertidamente con un empirismo de este tipo y, de este modo, su interpretación entra en tensión con el coherentismo de Davidson. Finalmente, discuto algunos aspectos de la interpretación que hace Duica de la tesis davidsoniana de la triangulación. (shrink)

We extend the languages of both basic and graded modal logic with the infinity diamond, a modality that expresses the existence of infinitely many successors having a certain property. In both cases we define a natural notion of bisimilarity for the resulting formalisms, that we dub $\mathtt {ML}^{\infty }$ and $\mathtt {GML}^{\infty }$, respectively. We then characterise these logics as the bisimulation-invariant fragments of the naturally corresponding predicate logic, viz., the extension of first-order logic with the infinity quantifier. Furthermore, for (...) both $\mathtt {ML}^{\infty }$ and $\mathtt {GML}^{\infty }$ we provide a sound and complete axiomatisation for the set of formulas that are valid in every Kripke frame, we prove a small model property with respect to a widened class of weighted models, and we establish decidability of the satisfiability problem.

This paper examines the value awarded by Duns Escoto to the defence of god -understood as Lave- who acts in a completely free mannner and is omnipotent. I also studies the implications of his philosophical position when confrontingthe relationships between faith and reason, theology and philosophy, intellect and will, necessity and contingency. His analysis of The Philosopher, Aristotle, is also discussed.

Su obra más importante fue: De Causa Dei con fra Pellagium et D e virtute causarum. En ella aborda profundamente un problema fundamental, discutido antes y después (sobre todo en los siglos XVI, XVII y XVIII): el de la libertad del hombre, el de la posible concordia entre necesidad y (...) libertad.

In this paper I argue that the Integrated Information Theory of Consciousness has an underlying emergentist metaphysics, specifically of a kind that has received minimal attention and we may call functionalist emergentism. I will try to show that in this scientific theory conscious experience is a functional-role property possessed by the whole system, not by their parts, which is dependent on, but also (purportedly) causally powerful over and above, the properties of the parts. However, I will argue that depicting conscious (...) experience as a functional-role emergent property threatens the whole coherence of the theory because, by definition, functional-realizers do all the causal work associated with the instantiation of any functional-role property on any occasion. Hence, to preserve the causal power of consciousness, which, as we will see, is one of the fundamental building blocks of the theory, linked to the assertion of the very existence of consciousness, phenomenal properties should be re-thought as realizers of the relevant informationally integrated causal-roles.

De acuerdo con la fenomenología husserliana la experiencia primordial del valor descansa en vivencias emotivas. Para sostener esta idea Husserl sugiere el paralelismo entre la percepción externa y la percepción de los valores. El objetivo de este trabajo es clarificar tal paralelismo enfatizando un problema particular del análisis husserliano: la tonalidad afectiva del objeto de valor y su relación con la apercepción sentimental involucrada en la experiencia de los valores.According to husserlian phenomenology the primordial experience of value lays in emotive (...) lived-experiences.

No resulta posible comprender el «sentido» de la historia humana si se prescinde de una «lectura ideológica» de sus procesos, entendiendo por tal la lectura que tematiza, como guía del análisis, la dependencia fundamental de las «formas mentales» respecto de los «intereses de clase» en el contexto de determinadas «relaciones de producción». Para Puente Ojea el estudio del estoicismo y del cristianismo ofrece una interesante oportunidad de verificar las virtualidades de la «lectura ideológica». Al análisis del cristianismo dedicó su (...) anterior libro, Ideología e historia. La formación del cristianismo como fenómeno ideológico (Siglo XXI de España Editores). El presente libro lo dedica al análisis del estoicismo. La madurez de la «sociedad antigua» coincide con el auge de nuevas «aperturas ideológicas», en cuyo discurso intelectual el problema del individuo y su felicidad personal ocupa un lugar preferente. Puede Ojea, utilizando el enfoque metodológico expuesto, analiza aquí las formas de articulación de esas nuevas aperturas ideológicas del pensamiento grecorromano con las estructuras socioeconómicas y la urdimbre política de aquella sociedad, en un intento de contrastar las pretensiones teóricas del materialismo histórico con su capacidad real de explicación histórica. En ese marco, el destino de las doctrinas estoicas y del modo de producción esclavista aparece nítidamente dibujado en su paralelo proceso. (shrink)

The paper outlines an attempt at phenomenological description of two intermingled dimensions of human vulnerability. First, vulnerability understood as an essential dimension in the constitution of embodiment and second, vulnerability in regard to trust, as a form of emotive interpersonal disposition. In either case, vulnerability does not only refer to mere physical fragility but to the situational horizon where from emerge progressive anticipations of “possible harm”. According to this account, vulnerability appears as a practical horizon of emotional awareness of risk (...) involving not only bodily fragility but a dimension of concrete existence of individual persons, namely, the intimate affectation of being harmed, injured or deprived or a practical aim. In this context the paper claims for a second and more radical sense of vulnerability that problematize the classical account of emotive protentionality, following Anthony Steinbock´s description of moral emotions. In this regard, vulnerability of trust involves an emotional risk and fragility that opens to consideration a dimension of human existence revealing human persons in their absolute and individual concreteness.

The Weber thesis on a hypothetical imprint of Protestantism in the «spirit» of capitalism has been widely spread. Not willing to discredit his proposal, the truth is that, being falsifiable with difficulty, some careless wordings have been derived from it claiming to explain the present economical circumstances through differential religious facts. Being religion an unparalleled all covering feature, such circumstances depend on many factors. It has been claimed some scientific status through the most diverse socioeconomic data. This is something also (...) applicable to those who claim to refute him. The intoxication so emanated from the Weber’s work seems disconcerting, seeing in it from an attempt to legitimate capitalism to a confirmation of the Black Legend. This work does not try to support or reject the thesis, but to investigate the kind of issues that could cause its formulation. For this purpose, it focuses on less usual questions, such as the analysis of the doctrinal features of Protestantism from which the Weber’s arguments would arise. (shrink)

En este trabajo, nos proponemos redefinir las posturas que toman parte en el debate entre realismo y antirrealismo científicos, dejando de concebirlas únicamente como doctrinas o teorías que describen cómo es el mundo. En cambio, acorde al camino iniciado por van Fraassen en The empirical stance, optamos por definirlas como stances: políticas, estrategias o perspectivas a partir de las cuales construimos creencias fácticas. Así, en primera instancia nos dedicamos a entender qué es una stance y cómo caracterizar esta noción. En (...) segundo lugar, exploramos metodologías y enfoques para tratar el realismo y el antirrealismo como stances, y, en esta clave, definirlos adecuadamente. Por último, examinamos el impacto de esta propuesta en la explicación de los acuerdos y desacuerdos en el debate, evaluando los grados de afinidad o distancia en las perspectivas en juego. (shrink)

In a recent remarkable article, Froese (2023) presents his Irruption Theory to explain how motivations can make a behavioral difference in motivated activity. In this opinion article, we review the main tenets of Froese’s theory, and highlight its difficulty in overcoming the randomness challenge it supposedly solves, that is, the issue of how adaptive behavior can arise in the face of material underdetermination. To advance our understanding of motivated behavior in line with Froese’s approach, we recommend that future work should (...) endorse a multilevel pluralistic approach to causation and explanation in which motivations could genuinely play an irreducible role. Additionally, in line with the life-mind continuity thesis, we suggest that the best place to look for the interplay between motivations and nonmotivational physical, biological, and dynamical factors, may be at the level of the continuous feeling of being an embodied, living organism.

Attempts to solve the issue of divine action in nature have resulted in many innovative proposals seeking to explain how God can act within nature without disrupting the created order but introducing novelty in the history of the universe.

The deep influence of affectivity on learning is now widely acknowledged (Keefer et al., 2018; Sánchez-Álvarez et al., 2021). For instance, it has been shown that affect influences key learning-relevant processes, such as motivation, perception, behavior, and critical thinking (Izard, 2002; Mayer & Salovey, 1997). Evidence also shows that emotion and mood strongly influence attention, which in turn drives learning and memory (Elbertson et al., 2010; Elias et al., 1997). Intersubjective phenomena, such as the degree of affection and respect between (...) child and teacher, also affect the child’s learning processes, academic outcomes, and brain development (Kusché & Greenberg, 2006; Ryan & Patrick, 2001). However, the relevant literature is not paying attention to increasing evidence showing that affective phenomena are rooted in interoceptive and homeostatic self- and co-regulatory processes within and between people’s living bodies (Barrett, 2017; Carvalho & Damasio, 2021; Craig, 2015, 2018; Fotopoulou et al., 2022; Fotopoulou & Tsakiris, 2017; Seth & Friston, 2016). In this theoretical chapter, we explore this connection and its importance for learning. We argue that affective experience plays a fundamental role in learning, and that affective experience is rooted in the homeostatic self-/co-regulation of living bodies. Therefore, the homeostatic self-/co-regulation of living bodies plays a fundamental role in learning. In other words, there is an intra- and interpersonal somatic dimension of learning that demands explicit consideration in educational contexts. In this way, we aim to contribute to an understanding of learning and education that moves away from an individualistic, brain-centered information-processing conception toward one centered on sentient, interdependent living bodies.

In consciousness studies there is a growing tendency to consider experience as (i) fundamentally affective and (ii) deeply interlinked with interoceptive and homeostatic bodily processes. However, this view still needs further development to be part of any rigorous theory of consciousness. To advance in this direction, we ask: (1) is there any affective type that is always present in consciousness?, (2) is it related to interoception and homeostasis?, and (3) what are its properties? Here we analyse and compare Jim Russell's (...) core affect and Thomas Fuchs' concept of vitality, and propose a more encompassing notion that subsumes both: continuous organismic sentience. It provides affirmative answers to questions 1 and 2, and, regarding question 3, a preliminary list of thirteen properties divided into ontological, phenomenological, and functional categories. This is the first of a series of studies that will systematically address different notions of a fundamental, homeostatically-rooted affective type, to achieve a rigorous, unified concept for consciousness science.

I welcome with great enthusiasm Meling and Scheidegger’s (2023; henceforth “M&S”) timely contribution to advance an enactive approach to psychedelic therapy, especially to the complex causality involved. Their two main research questions concerned:(i) the causal interaction between the psychedelic molecule and brain activity; and (ii) the causal interaction between brain activity and the psychedelic experience. While I largely agree with and celebrate much of what is proposed by M&S, especially their employment of key enactive concepts to advance our understanding of (...) the first research question, in the following, I will present some worries regarding their answers to the second. Although I agree that there is probably a two-way reciprocal relationship between neural activity and experience, I have several points of contention regarding M&S’s proposal. My hope is to stimulate discussion on M&S’s important contribution, and to help advance a much-needed enactive science of psychedelics. (shrink)
