The “default system” of the brain has been described as a set of regions which are ‘activated’ during rest and ‘deactivated’ during cognitively effortful tasks. To investigate the reliability of task-related deactivations, we performed a meta-analysis across 12 fMRI studies. Our results replicate previous findings by implicating medial frontal and parietal brain regions as part of the “default system”.However, the cognitive correlates of these deactivations remain unclear. In light of the importance of social cognitive abilities for human beings and their (...) propensity to engage in such activities, we relate our results to findings from neuroimaging studies of social cognition. This demonstrates a remarkable overlap between the brain regions typically involved in social cognitive processes and the “default system”.We, henceforth, suggest that the physiological ‘baseline’ of the brain is intimately linked to a psychological ‘baseline’: human beings have a predisposition for social cognition as the default mode of cognizing which is implemented in the robust pattern of intrinsic brain activity known as the “default system”.

During the last decade, one source of debate in argumentation theory has been the notion that there are different modes of arguing that need to be distinguished when analyzing and evaluating arguments. Visual argument is often cited as a paradigm example. This paper discusses the ways in which it and modes of arguing that invoke non-verbal sounds, smells, tactile sensations, music and other non-verbal entities may be defined and conceptualized. Though some attempts to construct a ‘multimodal’ theory of argument are (...) criticized, it advocates for an argumentation theory that makes room for visual arguing and for other non-verbal modes that have not been explored in depth. In the process, the paper provides a method for identifying the structure of multimodal arguments and argues that adding modes to our theoretical tool box is an important step toward a comprehensive account of argument.

Informal logic is an attempt to develop a logic that can assess and analyze the arguments that occur in natural language discourse. Discussions in the field may address instances of scientific, legal, and other technical forms of reasoning, but the overriding aim has been a comprehensive account of argument that can explain and evaluate the arguments found in discussion, debate and disagreement as they manifest themselves in daily life — in social and political commentary; in news reports and editorials in (...) the mass media ; in advertising and corporate and governmental communications; and in personal exchange.

Over the past few decades, Indigenous communities have successfully campaigned for greater inclusion in decision-making processes that directly affect their lands and livelihoods. As a result, two important participatory rights for Indigenous peoples have now been widely recognized: the right to consultation and the right to free, prior and informed consent (FPIC). Although these participatory rights are meant to empower the speech of these communities—to give them a proper say in the decisions that most affect them—we argue that the way (...) these rights have been implemented and interpreted sometimes has the opposite effect, of denying them a say or ‘silencing’ them. In support of this conclusion we draw on feminist speech act theory to identify practices of locutionary, illocutionary, and perlocutionary group silencing that arise in the context of consultation with Indigenous communities.

In the pioneering article and two papers, written jointly with McKinsey, Tarski developed the so-called algebraic and topological frameworks for the Intuitionistic Logic and the Lewis modal system. In this paper, we present an outline of modern systems with a topological tinge. We consider topological interpretation of basic systems GL and G of the provability logic in terms of the Cantor derivative and the Hausdorff residue.

The idea that Western philosophy is a footnote to Plato is simplistic and inaccurate. Much of modern and contemporary epistemology owes a debt not so much to Platonism or Aristotelianism as to their antithesis: scepticism. Recent discussions in the history of philosophy have sparked a great deal of interest in the ancient sceptics, but until now they have been misunderstood and the significance of their philosophy not fully appreciated.

In the paper ‘COVID-19 vaccine boosters for young adults: a risk–benefit assessment and ethical analysis of mandate policies at universities,’ Bardoshet alargued that college mandates of the COVID-19 booster vaccine are unethical. The authors came to this conclusion by performing three different sets of comparisons of benefits versus risks using referenced data and argued that the harm outweighs the risk in all three cases. In this response article, we argue that the authors frame their arguments by comparing values that are (...) not scientifically or reasonably comparable and that the authors used values that represent grossly different risk profiles and grouped them into a set of figures to create an illusion of fair comparisons. We argue that absent the falsely skewed portrayals of a higher level of risk over benefit in their misrepresented figures, the five ethical arguments they presented completely fall apart. (shrink)

Trans of Color inclusion is not simply a gesture of affectionate commitment to María Lugones's theory of impure communities. Rather, it is required for the enactment of her liberatory theory within and across communities of color. While María Lugones's historico-theoretical analysis of the colonial/modern gender system relies upon anthropological citations of Native gender and sexual diversity, she argues that we must bracket gender for the benefit of [cis]women of color feminisms. However, if this bracketing does not first carefully uncover cisgender (...) histories of violence, then this decolonial feminist praxis reinscribes the invisibility of transphobia, racism, and colonialism's violent intersections, performing another mode of erasure and silence on Trans, Two-Spirit, and Nonbinary Native, Black, and Latinx peoples. In placing Lugones's texts into conversation with the voices of Two-Spirit and Trans of Color theorists, I argue that the mutilation of trans flesh makes possible the integration of [cis]People of Color into the gender–sex binary even if as failures. More important, this essay offers the beginnings of a phenomenological account of Trans World-Traveling, where the unruliness of Two-Spirit and Trans of Color bodies cocoons decolonial worlds from within the spiraling folds of abject flesh—always already in infra-communication with ancestral pasts, presents, and futures.

Combating and overcoming corruption in business and in political affairs is one of the most important issues facing business and professional ethics in the 21st century. That corruption exists is a fact. That corruption is widespread and spreading is a commonperception. Many believe that corruption is culturally induced. Some believe corruption to be so much a part of the fabric of some societies as to be unquestioned and unassailable. Or, is it simply a myth that corruption is a matter of (...) culture? (shrink)

This article discusses “auditory” arguments: arguments in which non-verbal sounds play a central role. It provides examples and explores the use of sounds in argument and argumentation. It argues that auditory arguments are not reducible to verbal arguments but have a similar structure and can be evaluated by extending standard informal logic accounts of good argument. I conclude that an understanding of auditory elements of argument can usefully expand the scope of informal logic and argumentation theory.

Derek Parfit has recently defended the view that no one can ever deserve to suffer. Were this view correct, its implications for the thorny problem of the justification of punishment would be extraordinary: age-old debates between consequentialists and retributivists would simply vanish, as punishment would only—and simply—be justifiable along Benthamite utilitarian lines. I here suggest that Parfit’s view is linked to uncharacteristically weak arguments, and that it ought to be rejected.

This paper responds to two aspects of Ralph Johnson's Manifest Rationality (2000). The first is his critique of deductivism. The second is his failure to make room for some species of argument (e.g., visual and kisceral arguments) proposed by recent commentators. In the first case, Johnson holds that argumentation theorists have adopted a notion of argument which is too narrow. In the second, that they have adopted one which is too broad. I discuss the case Johnson makes for both claims, (...) and possible objections to his analysis. (shrink)

This is a review of Larry Alexander and Kim Ferzan’s _Reflections on Crime and Culpability_, a sequel to the authors’ _Crime and Culpability_. The two books set out a sweeping proposal for reforming our criminal law in ways that are at once commonsensical and mindbogglingly radical. But even if one is not on board with such a radical experiment, simply thinking it through holds many unexpected lessons: startlingly new insights about the current regime and about novel ways of doing legal (...) theory, some of which are explored in this essay.

In the Tractatus Logico-Philosophicus, Wittgenstein states that man has the ability to construct languages with which all meanings may be expressed, but that it is humanly impossible to immediately extract its logic from it. Thus, language is a costume that disguises thought while proposition is a figuration of reality. This paper is aimed at showing how the position of the Tractatus in relation to sciences puts aside the idea that scientific knowledge should be rooted in raw data, that is, observations (...) that may be made regardless of any theoretical orientation. Accordingly, this study claims that the Tractarian position does not admit the presumption that behind raw data there is a reality that is independent of the observer, considering that, as stated by Wittgenstein, the limits of language indicate the limits of the world, and not the other way around.

A new logic is presented without predicates—except equality. Yet its expressive power is the same as that of predicate logic, and relations can faithfully be represented in it. In this logic we also develop an alternative for set theory. There is a need for such a new approach, since we do not live in a world of sets and predicates, but rather in a world of things with relations between them.

Over the last decades we have seen an increased interest in forensic rhetoric in Plato's dialogues, notably in relation to hisApology. However, little interest has been paid to this strain of rhetoric in relation to theGorgias. In this article I focus on one notion, βοήθεια, as it was discussed in Plato'sGorgias. This notion had a wide currency in forensic rhetoric in classical Athens.

Hamkins and Löwe proved that the modal logic of forcing is S4.2 . In this paper, we consider its modal companion, the intermediate logic KC and relate it to the fatal Heyting algebra H ZFC of forcing persistent sentences. This Heyting algebra is equationally generic for the class of fatal Heyting algebras. Motivated by these results, we further analyse the class of fatal Heyting algebras.

At the confluence between Modern Olympism and Confucian teachings—nowadays embodied and expressed in East Asian Confucianisms—there are meaningful overlaps, significant challenges, and opportunities. This paper examines these. Despite radically different origins and apparently incommensurate tenets, we should not assume that the underlying ideals of Modern Olympism and East Asian Confucianisms cannot benefit mutually. It is precisely when considering their putative weak points, such as Modern Olympism's soft metaphysics or vague ethics or Confucianism's bias against physical activity or gender, that we (...) find educational opportunities that make contributions to a universal humanistic sport education.

The living forms represented in this paper are sets of parts that spontaneously increase in organization. Their organizations are measured by an information-theoretic function derived from the work of Boltzmann and Shannon. We briefly review its derivation in the context of the troubled role of mathematics in biology, and then define the function. We illustrate its nature by measuring the 22 different organizations of a set of eight things; and we facilitate its use by defining the parameters that determine an (...) amount of organization. The measure is then applied to show that the organization of limb pairs on free-living arthropods, based on data given by Cisne, confirms a pattern of increasing organization in their evolution from the Cambrian era to the present. Further applications measure the changes in organizations of ideal (theoretical) life forms, and contrasting changes in inanimate systems. Our main results represent the reproduction of unicellular organisms, and the formation of hierarchies, as processes of increasing organization. (shrink)

According to Margaret Gilbert, two or more people collectively believe that p if and only if they are jointly committed to believe that p as a body. But the way she construes joint commitment in her account – as a commitment of and by the several parties to “doing something as a body” – encourages the thought that the phenomenon accounted for is not that of genuine belief. I explain why this concern arises and explore a different way of construing (...) joint commitment, in order to avoid the concern. This leads me to propose a revised Gilbertian account of collective belief, according to which two or more people collectively believe that p if and only if they are jointly committed to p as true.

This article explores the meaning of the task of teaching students to formulate critique in relation to the so-called ‘pedagogical paradox’, according to which the educational ideal of individual autonomy is contradicted by the practice of planning and control, which is particularly pronounced in the influential model of ‘constructive alignment’. Taking Kant’s idea of enlightenment and autonomy as a starting point, I introduce Luc Boltanski’s concept of reflexivity and link it to Jon Elster’s discussion of ‘states that are essentially by-products’. (...) In doing so, I advance the view that genuine critique typically emerges from a shift in perspective, from the pragmatic realization of goals according to institutionalized practices to a metapragmatic reflection on those practices. Since teaching is itself an institutionalized practice, personal reflexivity can only be understood as a by-product of teaching, and, contra the logic of models like constructive alignment, it cannot be set as a direct objective. Emerging from the subject itself, rather than from the influence of an educational technique, personal reflexivity should be recognized as an important aspect of the subject’s transition from youth to maturity.

Michael Gilbert’s multi-modal theory of argument challenges earlier accounts of arguing assumed in formal and informal logic. His account of emotional, visceral, and kisceral modes of arguing rejects the assumption that all arguments must be treated as instances of one “logical mode.” This paper compares his alternative modes to other modes proposed by those who have argued for visual, auditory, and other “multimodal” modes of arguing. I conclude that multi-modal and multimodal (without the hyphen) modes are complementary. Collectively, they represent (...) an important attempt to radically expand the scope of informal logic and the argumentation that it studies. (shrink)

Throughout the long centuries of western metaphysics the problem of the infinite has kept surfacing in different but important ways. It had confronted Greek philosophical speculation from earliest times. It appeared in the definition of the divine attributed to Thales in Diogenes Laertius (I, 36) under the description "that which has neither beginning nor end. " It was presented on the scroll of Anaximander with enough precision to allow doxographers to transmit it in the technical terminology of the unlimited (apeiron) (...) and the indeterminate (aoriston). The respective quanti tative and qualitative implications of these terms could hardly avoid causing trouble. The formation of the words, moreover, was clearly negative or privative in bearing. Yet in the philosophical framework the notion in its earliest use meant something highly positive, signifying fruitful content for the first principle of all the things that have positive status in the universe. These tensions could not help but make themselves felt through the course of later Greek thought. In one extreme the notion of the infinite was refined in a way that left it appropriated to the Aristotelian category of quantity. In Aristotle (Phys. III 6-8) it came to appear as essentially re quiring imperfection and lack. It meant the capacity for never-ending increase. It was always potential, never completely actualized. (shrink)

Jean Baptiste Dumas, an outstanding research chemist and teacher, laid the foundations of the science of organic chemistry. While doing so, he gathered around him some thirty students who participated in his research programmes and for the most part worked in his laboratory, thus forming a laboratory-based research school of chemists. Several of these in their turn influenced the development of the science. In Part I the social and institutional aspects of the school were considered. The discussion in Part II (...) centres on student participation in Dumas's five programmes of research, arguably the most important determinant of membership in his school. As a general conclusion to the article, an assessment is made of the relationship between Dumas and his students. (shrink)
