¿De qué hablamos cuando decimos Diseño Sustentable? El diseño sustentable podría definirse como el diseño que tiene en cuenta los aspectos ambientales en todos los niveles de producción. Así mismo, persigue el objetivo de fabricar productos que aporten el menor impacto posible en el ecosistema a lo largo de todo el ciclo de vida. Es muy difícil encontrar productos de consumo que cumplan puntualmente con los Preceptos del eco diseño y que sean exitosos en el mercado. Ante esta situación es (...) necesario revisar los aspectos involucrados en la concepción de un nuevo producto: ¿El rol del diseñador es el adecuado?, ¿Existe una seria y responsable conciencia por parte de los empresarios para llevar adelante un proyecto de eco diseño?, ¿Son los productos eco lo suficientemente atractivos para captar la atención de los consumidores?

The study of complex systems, although an interdisciplinary endeavor, it is considered as an integrating part of physical sciences. Contrary to the historical fact that the eld is already mature, it still lacks a clear and unambiguous denition of its main object of study. Here, I propose a denition of complex systems based on the conceptual clarications made by Edgar Morin about the bidirectional non-separability of parts and whole produced by the nature of interactions. The concept to which I arrived (...) here is clear, not circular, neither too cryptic nor to explicit, and does not include any accompanying features of the own system dened. It allows, as shown in the paper, to derive some of the main properties that such systems must have as well as to propose its mathematical formalization. (shrink)

*Runner-up for the 2021 Royal Institute for Philosophy Essay Prize*: What should we think about ‘acts of conscience’, viz., cases where our personal judgments and public authority come into conflict such that principled resistance to the latter seems necessary? Philosophers mainly debate two issues: the Accommodation Question, i.e., ‘When, if ever, should public authority accommodate claims of conscience?’ and the Justification Question, i.e., ‘When, if ever, are we justified in engaging in acts of conscience – and why?’. By contrast, a (...) third important topic – the Conduct Question, i.e., ‘How should we act, morally speaking, when engaging in acts of conscience?’ – has been mostly neglected. This paper aims to offer concrete guidance for persons wishing to engage in acts of conscience in morally virtuous ways. I argue that such agents are subject to two basic prima facie duties: duties to oneself related to demands of integrity and duties to others related to demands of civility. I explain both duties in detail, arguing with regard to, that in light of what I call ‘the paradox of conscience’, we need to rethink our views about both ‘conscience’ and ‘integrity’; and with regard to, that, building upon Rawls’ ‘duty of civility’, we should embrace at least seven general principles for undertaking acts of conscience in a morally conscientious manner.

Can addiction be credibly invoked as an excuse for moral harms secondary to particular decisions to use drugs? This question raises two distinct sets of issues. First, there is the question of whether addiction is the sort of consideration that could, given suitable assumptions about the details of the case, excuse or mitigate moral blameworthiness. Most discussions of addiction and moral responsibility have focused on this question, and many have argued that addiction excuses. Here I articulate what I take to (...) be the best argument for this view, based on the substantial difficulty that people with severe addiction experience in controlling drug-related behavior. This, I argue, may in some cases be sufficient to ground a mitigating excuse, given the way in which addiction undermines agents’ responsiveness to relevant moral reasons to do otherwise. Much less attention has been devoted to a second set of issues that critically affect the possibility of applying this mitigating excuse in particular cases, derived from the ambivalent nature of agential control in addiction. In order to find a fitting response to moral harm, the person with the right standing to blame must make a judgment about the extent to which the agent possessed certain morally relevant capacities at the time of the act. In practice, this will often prove tremendously difficult to assess. The ethical challenge for the person with the right standing to blame is fundamentally one of making a judgment about matters that seem underdetermined by the available evidence. (shrink)

According to Marshall et al. (2024), some of the patients who refuse to stay in observation after being resuscitated following an opioid overdose are likely not making an autonomous choice. While I do not intend to dispute this claim, it merits discussion what is the concept of autonomy at play in making this assessment. I contend that the concept at work is more substantive than Marshall et al. acknowledge—and more substantive, too, than the form of autonomy usually thought to underpin (...) the moral justification of the requirement of informed consent .

In this chapter, Grace Andrus de Laguna and Theodore de Laguna critically examine the pragmatist theory of knowledge and offer their own alternative to it.

A restrictive view of self-control identifies exercises of self-control with synchronic intrapsychic processes, and pictures diachronic and externally-scaffolded strategies not as proper instances of self-control, but as clever ways of avoiding the need to exercise that ability. In turn, defenders of an inclusive view of self-control typically argue that we should construe self-control as more than effortful inhibition, and that, on grounds of functional equivalence, all these diverse strategies might be properly described as instances of self-control. In this paper, I (...) take a fresh look at this debate by focusing on cases of addiction. I argue that addicted agents face a paradigmatic sort of self-control challenge, which makes addiction an important test case for theories of self-control. And I discuss evidence that highlights both the unreliability of synchronic intrapsychic strategies and the crucial role that is played by diachronic and externally-scaffolded strategies in successful attempts at achieving abstinence by addicted individuals. Abstaining addicts are a paradigmatic case of agents who successfully exercise self-control, and they mostly do so by relying on diachronic and externally-scaffolded strategies. This, I argue, lends further support to an inclusive view of self-control. (shrink)

In this chapter, Grace Andrus de Laguna presents and argues for perspectivism about perception.

Presentism is, roughly, the ontological view that only the present exists. Among the philosophers engaged in the metaphysics of time there is wide agreement that presentism is intuitive (or commonsensical) and that its intuitiveness counts as evidence in its favour. My contribution has two purposes: first, defending the view that presentism is intuitive from some recent criticisms; second, putting forth a genealogical (or debunking) argument aimed at depriving presentism’s intuitiveness of the evidential value commonly granted to it.

In a series of recent papers Francesco Orilia has presented an argument for the moral desirability of presentism. It goes, in brief, as follows: since the existence of painful events is morally undesirable, presentism, which denies that past painful events (tenselessly) exist, is morally more desirable than non-presentism, which instead affirms that past painful events (tenselessly) exist. An objection against this argument, which has already been taken into consideration by Orilia, is the ugly history objection or radical objection: what really (...) matters in the moral appraisal of a world is the history of it, and since the presentist and the non-presentist versions of our world share the same ugly history, they are morally on a par. This paper aims at corroborating this objection and defending it from Orilia’s criticisms. This will be done by bringing into play various thought experiments and a distinction between relevance (of an event or a fact about the occurrence of an event) to the moral evaluation of a world and moral (and psychological) involvement (in an event or in a fact about the occurrence of an event). (shrink)

It is often assumed that, except perhaps in a few rare cases, people with addiction can be aptly held responsible for having acquired the condition. In this chapter, I consider the argument that supports this view and draw attention to a number of challenges that can be raised against it. Assuming that early decisions to use drugs were made in possession of normal-range psychological capacities, I consider the key question of whether drug users who later became addicted should have known (...) that addiction was a likely outcome of their decisions to use drugs in a way that makes them blameworthy for their lack of foresight. I focus on three different points of contention surrounding this claim: how likely the outcome to be predicted was, how tolerable risk should be weighed against the expected value of decisions to use, and how reliable the relevant predictive abilities of the average person are. Once we consider in some detail what would have to be true in order for someone to be aptly held responsible for becoming addicted, the prospects for making a convincing case to that effect look, I argue, somewhat more uncertain than they might at first appear.

Following the proposal of a new kind of selective structural realism that uses as a basis the distinction between framework and interaction theories, this work discusses relevant applications in fundamental physics. An ontology for the different entities and properties of well-known theories is thus consistently built. The case of classical field theories—including general relativity as a classical theory of gravitation—is examined in detail, as well as the implications of the classification scheme for issues of realism in quantum mechanics. These applications (...) also shed light on the different range of applicability of the ontic and epistemic versions of structural realism. (shrink)

While some form of loss of control is often assumed to be a common feature of the diverse manifestations of addiction, it is far from clear how loss of control should be understood. In this paper, I put forward a concept of decrease in control in addiction that aims to fill this gap and thus provide a general framework for thinking about addictive behavior. The development of this account involves two main steps. First, I present a view of degrees of (...) control as the degree to which an agent would be responsive to potential or counterfactual sufficient reasons to do otherwise. Second, I sketch an account of the relevant control-undermining factors in addiction that is consonant with my proposed view of degrees of control. Being a high-level functional property, reasons-responsiveness is particularly well suited to frame an account of control-undermining factors that is doubly pluralistic: it encompasses the contribution of factors both internal and external to the agent, and it is consistent with various proposals as to the precise nature of the anomaly taking place in the psychology of addiction.

We discuss the mathematical structures that underlie quantum probabilities. More specifically, we explore possible connections between logic, geometry and probability theory. We propose an interpretation that generalizes the method developed by R. T. Cox to the quantum logical approach to physical theories. We stress the relevance of developing a geometrical interpretation of quantum mechanics.

Intuitively, we can conceive of the existence of a conscious state as a pure activity that does not necessarily require a body (or even a brain). This idea has found new support in certain recent theories that present the possibility of a totally disconnected and disembodied consciousness. Against this hypothesis, I argue that human experience is intrinsically embodied and embedded, though in a specific way. Using Sartre’s phenomenology of the body, I first analyze the concept of consciousness as intentionality and (...) a world-disclosing activity, thus explaining how conscious activity can only be expressed through a body that is spatiotemporally related to the world. Then, I argue that bodily consciousness does not necessarily imply the actual presence of an anatomical body but, rather, a process of spatialization and temporalization (hodological space and temporal synthesis) through the “spatiotemporal body”. Finally, I test my thesis by critiquing some cases of apparent disembodied/disconnected consciousness, i.e., dreams, out-of-body experiences, and the brain-in-a-vat scenario. (shrink)

In this paper we discuss the extent to which the very existence of substructural logics puts the Tarskian conception of logical systems in jeopardy. In order to do this, we highlight the importance of the presence of different levels of entailment in a given logic, looking not only at inferences between collections of formulae but also at inferences between collections of inferences—and more. We discuss appropriate refinements or modifications of the usual Tarskian identity criterion for logical systems, and propose an (...) alternative of our own. After that, we consider a number of objections to our account and evaluate a substantially different approach to the same problem. (shrink)

When discussing Logical Pluralism several critics argue that such an open-minded position is untenable. The key to this conclusion is that, given a number of widely accepted assumptions, the pluralist view collapses into Logical Monism. In this paper we show that the arguments usually employed to arrive at this conclusion do not work. The main reason for this is the existence of certain substructural logics which have the same set of valid inferences as Classical Logic—although they are, in a clear (...) sense, non-identical to it. We argue that this phenomenon can be generalized, given the existence of logics which coincide with Classical Logic regarding a number of metainferential levels—although they are, again, clearly different systems. We claim this highlights the need to arrive at a more refined version of the Collapse Argument, which we discuss at the end of the paper. (shrink)

This paper explores the concept of moral expertise in the contemporary philosophical debate, with a focus on three accounts discussed across moral epistemology, bioethics, and virtue ethics: an epistemic authority account, a skilled agent account, and a hybrid model sharing key features of the two. It is argued that there are no convincing reasons to defend a monistic approach that reduces moral expertise to only one of these models. A pluralist view is outlined in the attempt to reorient the discussion (...) about moral expertise. (shrink)

In this paper, I attempt to synthesize the two most influential contemporary ethical approaches that appeal to moral intuitions, viz., Rawlsian reflective equilibrium and Audi’s moderate intuitionism. This paper has two parts. First, building upon the work of Audi and Gaut, I provide a more detailed and nuanced account of how these two approaches are compatible. Second, I show how this novel synthesis can both (1) fully address the main objections to reflective equilibrium, viz., that it provides neither necessary nor (...) sufficient conditions for the justification of our moral beliefs and (2) help ethical intuitionism to deal with the fundamental problem of peer disagreement over our basic moral intuitions. In doing so, I sketch out a novel and attractive diachronic way of thinking about peer disagreement more generally. (shrink)

In this paper I look into a problem concerning the characterization of the main conceptual commitments of the ‘post-cognitivist’ theoretical framework. I first consider critically a proposal put forward by Rowlands (2010), which identifies the theoretical nucleus of post-cognitivism with a convergence of the theses of the extended and the embodied mind. The shortcomings I find in this proposal lead me to an indepedent and wider issue concerning the apparent tensions between functionalism and the embodied and enactive approaches.

In this work, we focus on the philosophical aspects and technical challenges that underlie the axiomatization of the non-Kolmogorovian probability framework, in connection with the problem of quantum contextuality. This fundamental feature of quantum theory has received a lot of attention recently, given that it might be connected to the speed-up of quantum computers—a phenomenon that is not fully understood. Although this problem has been extensively studied in the physics community, there are still many philosophical questions that should be properly (...) formulated. We analyzed different problems from a conceptual standpoint using the non-Kolmogorovian probability approach as a technical tool. (shrink)

In filosofia spesso si segue un metodo stando al quale una tesi o teoria che sia più in sintonia con il senso comune deve essere preferita alle posizioni meno in sintonia con esso, per lo meno fino a quando non si mostri che quella tesi o teoria è inadeguata e che una delle posizioni avverse costituisce un adeguato sostituto. Nel presente contributo si vuole offrire una caratterizzazione della nozione di senso comune generalmente in uso nei dibattiti filosofici contemporanei; illustrare criticamente (...) i principali metodi impiegabili per determinare contenuti filosoficamente rilevanti del senso comune; chiarire e giustificare il metodo filosofico dell'appello al senso comune; presentare, d'altro canto, alcune delle strategie argomentative attuabili da chi si trovi a sostenere una tesi o teoria contrastante con il senso comune.

A música pode causar emoções fortes. Como havemos de compreender as respostas afetivas à música? Este artigo apresenta os principais enigmas filosóficos atinentes às emoções musicais. O problema principal diz respeito ao chamado "contágio": os ouvintes percebem a música como sendo expressiva de uma certa emoção (por exemplo, tristeza) e a música suscita neles essa mesma emoção. O contágio é desconcertante, pois entra em conflito com a principal teoria da emoção, de acordo com a qual as emoções são experiências de (...) valores (cognitivismo). Este artigo gira, sobretudo, em torno da apresentação crítica das várias respostas a este desafio ao cognitivismo. Apresenta, também, o paradoxo da música triste, isto é, a questão do motivo pelo qual apreciamos música triste. -/- Music can induce strong emotions. How are we to understand affective responses to music? This article presents the main philosophical puzzles pertaining to musical emotions. The chief problem concerns so-called "contagion": listeners perceive music as expressive of some emotion (say, sadness), and the music elicits the same emotion in them. Contagion is perplexing because it collides with the leading theory of emotion, according to which emotions are experiences of values (cognitivism). This article mostly revolves around the critical presentation of the various responses to this challenge to cognitivism. It also presents the paradox of sad music, i.e. the question of why we enjoy sad music. (shrink)

This paper argues that the crucial feature of the drug-related desires experienced by addicted agents is not that they ‘push’ the agent with a force she cannot oppose, but that they are not easily undermined by things that normally have the ability to undermine desires —in other words, that they are extraordinarily recalcitrant. As a result, the disposition to experience these desires is very persistent over the long-term, manifesting itself in particular episodes of wanting to use drugs that recur with (...) great frequency. Both the persistence and the recurrence of these desires, it is argued, contribute to a diminished ability to respond to relevant reasons that speak against drug use. (shrink)

Philosophy has always been concerned with mental health and mental disorder, and many prominent historical figures have held views that have drawn attention to these issues. In recent years, however, there has been a surge of interest in philosophical issues surrounding psychiatry. As a result, the philosophy of psychiatry has emerged as a distinct, well-established field of inquiry.

The question I address in this paper is what is it exactly for desires to possess a certain strength. And my aim is twofold. First, I argue for a pluralistic account of desire strength. On this view, there are several dimensions along which desires possess greater or lesser strength, and none of them is intrinsically privileged. My second aim is to highlight some time-based properties of desires, recurrence and persistence. Both desires’ degree of persistence across time and their rate of (...) episodic recurrence are, I argue, further dimensions of desire strength. (shrink)

Las soluciones a la paradoja de la ficción propuestas por Kendall Walton y Gregory Currie, a pesar de diferir en puntos de detalle importantes, suponen dos movimientos conceptuales comunes para entender la situación de quien está inmerso en una obra de ficción, a través del recurso a la noción de “cuasi-emociones” y de la idea de construcción de escenarios imaginarios. Aquí propondré que sus propuestas fallan en sus dos puntos centrales, a partir de problemas que son, sin embargo, independientes. Por (...) un lado, sus ideas sobre las emociones que sentimos al estar atrapados por una obra de ficción fallan al suponer una versión inaceptable de la tesis cognitivista acerca de las emociones. Por otro, sus ideas sobre la construcción de mundos imaginarios por parte de los “consumidores de ficción” fallan al suponer una dicotomía entre mundos de ficción y realidad. Finalmente, discutiré brevemente el modo en que ambos tipos de problemas repercuten sobre la viabilidad del planteo de la paradoja misma. (shrink)

En este trabajo analizo el entramado conceptual de la concepción causal de la metáfora (Davidson 1978). Para ello me enfocaré en primer lugar en su discusión con las concepciones semánticas, lo que nos llevará a discutir el tratamiento davidsoniano de la noción de significado y su distinción entre significado de la oración y significado del hablante. Luego plantearé un problema interno a este enfoque, en términos de cómo entender esta última distinción dentro del marco nominalista del pragmatismo davidsoniano. Finalmente, analizaré (...) las consecuencias de adoptar este enfoque a la hora de pensar a las metáforas como vehículos para la transmisión de contenido cognitivo. (shrink)

In the Indian philosophical debate, the relationship between the structure of knowledge and external reality has been a persistent issue. This debate has been particularly prominent in Buddhism, as evidenced by the earliest Buddhist attestations in the Pāli canon, where reality is described as a perceptual defection. The world (loka) is perceived through cognition (citta), and the theme of designation (paññatti) is central to the analysis of the Abhidhamma. Buddhism can be viewed as navigating between nominalism and cognitive normativism, as (...) it deconstructs language, which is seen as an obfuscating element that separates the subject from the world. In this article, we explore these issues through a philosophical dialogue between Early Buddhism, Abhidhamma, and Madhyamaka, utilizing methodological tools from Western philosophical traditions, both ancient and modern. We engage in a clash between nihilism and absolutism, in search of the substantiality of entities, which, behind the emptiness of conventional designations, conceals a complex fractal network of pansematism.

We study the origin of quantum probabilities as arising from non-Boolean propositional-operational structures. We apply the method developed by Cox to non distributive lattices and develop an alternative formulation of non-Kolmogorovian probability measures for quantum mechanics. By generalizing the method presented in previous works, we outline a general framework for the deduction of probabilities in general propositional structures represented by lattices (including the non-distributive case).

People display recognizably characteristic behavioral patterns across time and situations, with a given degree of regularity. These patterns may justify the attribution of personality traits. It is arguably the commonsense view that the proper explanation of these behavioral regularities is given by intrinsic properties of the agent’s psychology. In this paper, I argue for an externalistic view of the causal basis of personality-characteristic behaviors. According to the externalistic view, the relevant behavioral regularities are better understood as the result of a (...) systematic interaction between features internal to the agent and environmental-situational factors. Moreover, if the premise is granted that people are typically able to exercise a certain degree of control over the environmental-situational conditions they find themselves in, the resulting picture is of active sort of externalism, as people may at times engage in selection and manipulation of environmental-situational conditions as a way of managing their own behavioral tendencies.

En este trabajo me propongo explorar algunas consecuencias que implica adoptar una lectura disolutoria fuerte de las Investigaciones Filosóficas de Wittgenstein. A tal fin, recorreré los textos clave para la lectura disolutoria y exploraré la relación que tal concepción guarda con el estilo de composición de la obra, a partir de la clarificación del tipo de objetivo que Wittgenstein se propone.

Quantum Mechanics is a fundamental physical theory about atomic-scale processes. It was built between 1920 and 1940 by the most distinguished physicists of that time. The accordance between the predictions of the theory and experimental results is remarkable. The physical interpretation of its mathematical constructs, however, raised unprecedented controversies. Ontological, semantic, and epistemic vagueness abound in the orthodox interpretations and have resulted in serious misunderstandings that are often repeated in textbooks and elsewhere. In this work, we identify, criticize, and clarify (...) the most spread ones. (shrink)

We discuss the relationship between logic, geometry and probability theory under the light of a novel approach to quantum probabilities which generalizes the method developed by R. T. Cox to the quantum logical approach to physical theories.

In this article, we will present a number of technical results concerning Classical Logic, ST and related systems. Our main contribution consists in offering a novel identity criterion for logics in general and, therefore, for Classical Logic. In particular, we will firstly generalize the ST phenomenon, thereby obtaining a recursively defined hierarchy of strict-tolerant systems. Secondly, we will prove that the logics in this hierarchy are progressively more classical, although not entirely classical. We will claim that a logic is to (...) be identified with an infinite sequence of consequence relations holding between increasingly complex relata: formulae, inferences, metainferences, and so on. As a result, the present proposal allows not only to differentiate Classical Logic from ST, but also from other systems sharing with it their valid metainferences. Finally, we show how these results have interesting consequences for some topics in the philosophical logic literature, among them for the debate around Logical Pluralism. The reason being that the discussion concerning this topic is usually carried out employing a rivalry criterion for logics that will need to be modified in light of the present investigation, according to which two logics can be non-identical even if they share the same valid inferences.

The aim of this article is to discuss the extent to which certain substructural logics are related through the phenomenon of duality. Roughly speaking, metainferences are inferences between collect...

Temporal ontology is the philosophical debate on the existence of the past and the future. It features a three-way confrontation between supporters of presentism (the present exists, the past and the future do not), pastism (the past and the present exist, the future does not), and eternalism (the past, the present, and the future all exist). Most philosophers engaged in this debate believe that presentism is much more in agreement with common sense than the rival views; moreover, most of them (...) believe that being in agreement with common sense is epistemically valuable for a philosophical view. We studied experimentally non-experts’ ideas pertaining to the domain of temporal ontology, i.e., as we called it, common-sense temporal ontology, focusing on the Italian population. We found that a non-overwhelming majority of participants (~64%) favoured presentism, while two significant minorities favoured pastism (~19%) and eternalism (~17%). We think that our findings provide some support, albeit weaker than expected, for the view that presentism is more in agreement with common sense than the rival positions. (shrink)

Kant’s metaphilosophy has three main parts: (1) an essentialist project (“What is philosophy?”); (2) a methodological project (“How do we do philosophy?”); and (3) a taxonomic project (“What are the different parts of philosophy, and how are they related?”). This paper focuses on the third project. In particular, it explores one of the most intriguing yet puzzling aspects of Kant’s philosophy, viz. the relationship between what Kant calls ‘pure’ philosophy vs. ‘applied’, ‘empirical’ or what we can broadly refer to as (...) ‘impure’ philosophy. (As we shall see, in order to be able to address this third project, we shall also need to examine the other two projects in detail.) My plan is as follows. First, I discuss four main areas of pure vs. impure philosophy: (i) ‘pure logic’ vs. ‘applied logic’; (ii) ‘rational psychology’ vs. ‘empirical psychology’; (iii) ‘pure metaphysics of nature’ vs. ‘physics’ and (iv) ‘pure morality’ or a ‘metaphysics of morals’ vs. ‘moral anthropology’, ‘practical anthropology’ or ‘applied moral philosophy’. Based on this, I identify four key differences between pure and impure philosophy. Second, I critically examine four different readings of Kant’s views about the status of ‘impure’ philosophy: (a) that it is not genuine philosophy; (b) that it is bad or inferior philosophy; (c) that it is instrumentally valuable; and (d) that it constitutes an indispensable part of Kant’s philosophy, both in a theoretical and practical sense. I argue that Kant is best interpreted as endorsing readings (c) and (d). Third, I offer some concluding remarks. (shrink)

Paraconsistent logics are logical systems that reject the classical principle, usually dubbed Explosion, that a contradiction implies everything. However, the received view about paraconsistency focuses only the inferential version of Explosion, which is concerned with formulae, thereby overlooking other possible accounts. In this paper, we propose to focus, additionally, on a meta-inferential version of Explosion, i.e. which is concerned with inferences or sequents. In doing so, we will offer a new characterization of paraconsistency by means of which a logic is (...) paraconsistent if it invalidates either the inferential or the meta-inferential notion of Explosion. We show the non-triviality of this criterion by discussing a number of logics. On the one hand, logics which validate and invalidate both versions of Explosion, such as classical logic and Asenjo–Priest’s 3-valued logic LP. On the other hand, logics which validate one version of Explosion but not the other, such as the substructural logics TS and ST, introduced by Malinowski and Cobreros, Egré, Ripley and van Rooij, which are obtained via Malinowski’s and Frankowski’s q- and p-matrices, respectively.

The informal logic movement began as an attempt to develop – and teach – an alternative logic which can account for the real life arguing that surrounds us in our daily lives – in newspapers and the popular media, political and social commentary, advertising, and interpersonal exchange. The movement was rooted in research and discussion in Canada and especially at the University of Windsor, and has become a branch of argumentation theory which intersects with related traditions and approaches (notably formal (...) logic, rhetoric and dialectics in the form of pragma-dialectics). In this volume, some of the best known contributors to the movement discuss their views and the reasoning and argument which is informal logic’s subject matter. Many themes and issues are explored in a way that will fuel the continued evolution of the field. Federico Puppo adds an insightful essay which considers the origins and development of informal logic and whether informal logicians are properly described as a “school” of thought. In considering that proposition, Puppo introduces readers to a diverse range of essays, some of them previously published, others written specifically for this volume. (shrink)

This article presents an analysis of the bust of Galileo that Vincenzo Vela created for his house and studio at Ligornetto. The work carries symbolic significance in that it was conceived by the Ticinese artist for the pilaster on the right hand side of the principal entrance to the villa, as a counterpart to the bust of Christopher Columbus on the left. It thus served to perpetuate a long-standing literary topos which started at the beginning of the 17th century and (...) which was made use of during the Risorgimento to celebrate Italian ascendency within a European context. Through this work Vela reveals his adherence to patriotic ideals that he had previously expressed through his active participation in the first Italian War of Independence, fighting in the anti-Austrian ranks.

We provide here irrefutable facts that prove the falsehood of the claims published in [1] by Dehmer and Mowshowitz (DM) against our paper published in [2]. We first prove that Dehmer’s definition of node probability [3] is flawed. In addition, we show that it was not Dehmer in [3] who proposed this definition for the first time. We continue by proving how the use of Dehmer’s definition does not reveal all the physico-mathematical richness of the walk entropy of graphs. Finally, (...) we show a few facts about the failure of DM themselves to cite properly the relevant literature in their field.

In some recent articles, Cobreros, Egré, Ripley, & van Rooij have defended the idea that abandoning transitivity may lead to a solution to the trouble caused by semantic paradoxes. For that purpose, they develop the Strict-Tolerant approach, which leads them to entertain a nontransitive theory of truth, where the structural rule of Cut is not generally valid. However, that Cut fails in general in the target theory of truth does not mean that there are not certain safe instances of Cut (...) involving semantic notions. In this article we intend to meet the challenge of answering how to regain all the safe instances of Cut, in the language of the theory, making essential use of a unary recovery operator. To fulfill this goal, we will work within the so-called Goodship Project, which suggests that in order to have nontrivial naïve theories it is sufficient to formulate the corresponding self-referential sentences with suitable biconditionals. Nevertheless, a secondary aim of this article is to propose a novel way to carry this project out, showing that the biconditionals in question can be totally classical. In the context of this article, these biconditionals will be essentially used in expressing the self-referential sentences and, thus, as a collateral result of our work we will prove that none of the recoveries expected of the target theory can be nontrivially achieved if self-reference is expressed through identities.
