Metabolic dysfunction is a ubiquitous underlying feature of many neurological conditions including acute traumatic brain injuries and chronic neurodegenerative conditions. A central problem in neurological patients, in particular those with traumatic brain injuries, is an impairment in the utilization of glucose, which is the predominant metabolic substrate in a normally functioning brain. In such patients, alternative substrates including ketone bodies and lactate become important metabolic candidates for maintaining brain function. While the potential neuroprotective benefits of ketosis have been recognized for (...) up to almost a century, the majority of work has focused on the use of ketogenic diets to induce such a state, which is inappropriate in cases of acute disease due to the prolonged periods of time (i.e., weeks to months) required for the effects of a ketogenic diet to be seen. The following review seeks to explore the neuroprotective effects of exogenous ketone and lactate preparations, which have more recently become commercially available and are able to induce a deep ketogenic response in a fraction of the time. The rapid response of exogenous preparations makes their use as a therapeutic adjunct more feasible from a clinical perspective in both acute and chronic neurological conditions. Potentially, their ability to globally moderate long-term, occult brain dysfunction may also be relevant in reducing lifetime risks of certain neurodegenerative conditions. In particular, this review explores the association between traumatic brain injury and contusion-related dementia, assessing metabolic parallels and highlighting the potential role of exogenous ketone and lactate therapies.

Dialetheism is the metaphysical claim that there are true contradictions. And based on this view, Graham Priest and his collaborators have been suggesting solutions to a number of paradoxes. Those paradoxes include Russell’s paradox in naive set theory. For the purpose of dealing with this paradox, Priest is known to have argued against the presence of classical negation in the underlying logic of naive set theory. The aim of the present paper is to challenge this view by showing that there (...) is a way to handle classical negation. (shrink)

This edited volume collects essays on the four-valued logic known as Belnap-Dunn logic, or first-degree entailment logic. It also looks at various formal systems closely related to it. These include the strong Kleene logic and the Logic of Paradox. Inside, readers will find reprints of seminal papers written by the fathers of the field: Nuel Belnap and Michael Dunn. In addition, the collection also features a well-known but previously unpublished manuscript of Dunn, an interview with Belnap, and a new essay (...) by Dunn. Besides the original, monumental papers, the book also includes research by leading scholars. They consider the extraordinary importance of Belnap-Dunn logic from several perspectives. They look at how, philosophically, it has served as a basic system of inconsistency-tolerant reasoning, as the core of underlying logics for theories based on dialetheism, and, more recently, for theories based on Buddhist philosophy. Coverage also explores its contributions to computer science, such as knowledge representation and information processing. This mix of seminal papers and insightful analysis by top scholars offers readers a comprehensive outlook on Belnap-Dunn logic and its related expansions, which have been agenda setting for the debate on philosophical logic as well as philosophy of logic. The book will also enhance further discussion on the philosophical issues related to nonclassical logics in general. (shrink)

We outline the rather complicated history of attempts at axiomatizing Jaśkowski’s discussive logic $$\mathbf {D_2}$$ D2 and show that some clarity can be had by paying close attention to the language we work with. We then examine the problem of axiomatizing $$\mathbf {D_2}$$ D2 in languages involving discussive conjunctions. Specifically, we show that recent attempts by Ciuciura are mistaken. Finally, we present an axiomatization of $$\mathbf {D_2}$$ D2 in the language Jaśkowski suggested in his second paper on discussive logic, by (...) following a remark of da Costa and Dubikajtis. We also deal with an interesting variant of $$\mathbf {D_2}$$ D2, introduced by Ciuciura, in which negation is also taken to be discussive. (shrink)

In this paper we discuss the extent to which conjunction and disjunction can be rightfully regarded as such, in the context of infectious logics. Infectious logics are peculiar many-valued logics whose underlying algebra has an absorbing or infectious element, which is assigned to a compound formula whenever it is assigned to one of its components. To discuss these matters, we review the philosophical motivations for infectious logics due to Bochvar, Halldén, Fitting, Ferguson and Beall, noticing that none of them discusses (...) our main question. This is why we finally turn to the analysis of the truth-conditions for conjunction and disjunction in infectious logics, employing the framework of plurivalent logics, as discussed by Priest. In doing so, we arrive at the interesting conclusion that —in the context of infectious logics— conjunction is conjunction, whereas disjunction is not disjunction. (shrink)

In this introduction, we offer an overview of main systems developed in the growing literature on connexive logic, and also point to a few topics that seem to be collecting attention of many of those interested in connexive logic. We will also make clear the context to which the papers in this special issue belong and contribute.

Recent policy changes in the European Union have introduced the requirement for publicly funded research to be published in open access. This can be seen as part of a mode of democratic accountability that not only promotes transparency but also, Naomi Hodgson argues, is constituted by visibility and openness. By drawing attention to the way in which the researcher is asked to understand herself in this policy context, Hodgson illustrates how particular technologies of performance measurement and management, and of (...) publication, enter the researcher into this economy of visibility. The understanding of openness as a corrective to the traditional closed access system of publishing and the marketization of academia is challenged, then, in this article, which indicates how these technologies of reading and writing constitute the researcher as a particular figure in the emergent mode of governance.

In this introduction to the special issue “40 years of FDE”, we offer an overview of the field and put the papers included in the special issue into perspective. More specifically, we first present various semantics and proof systems for FDE, and then survey some expansions of FDE by adding various operators starting with constants. We then turn to unary and binary connectives, which are classified in a systematic manner. First-order FDE is also briefly revisited, and we conclude by listing (...) some open problems for future research. (shrink)

The U.S. scientific community has long led the world in research on such areas as public health, environmental science, and issues affecting quality of life. These scientists have produced landmark studies on the dangers of DDT, tobacco smoke, acid rain, and global warming. But at the same time, a small yet potent subset of this community leads the world in vehement denial of these dangers. -/- Merchants of Doubt tells the story of how a loose-knit group of high-level scientists and (...) scientific advisers, with deep connections in politics and industry, ran effective campaigns to mislead the public and deny well-established scientific knowledge over four decades. Remarkably, the same individuals surface repeatedly-some of the same figures who have claimed that the science of global warming is "not settled" denied the truth of studies linking smoking to lung cancer, coal smoke to acid rain, and CFCs to the ozone hole. "Doubt is our product," wrote one tobacco executive. These "experts" supplied it. -/- Naomi Oreskes and Erik M. Conway, historians of science, roll back the rug on this dark corner of the American scientific community, showing how ideology and corporate interests, aided by a too-compliant media, have skewed public understanding of some of the most pressing issues of our era.

Are doctors right when they tell us vaccines are safe? Should we take climate experts at their word when they warn us about the perils of global warming? Why should we trust science when so many of our political leaders don't? Naomi Oreskes offers a bold and compelling defense of science, revealing why the social character of scientific knowledge is its greatest strength--and the greatest reason we can trust it. Tracing the history and philosophy of science from the late (...) nineteenth century to today, this timely and provocative book features a new preface by Oreskes and critical responses by climate experts Ottmar Edenhofer and Martin Kowarsch, political scientist Jon Krosnick, philosopher of science Marc Lange, and science historian Susan Lindee, as well as a foreword by political theorist Stephen Macedo.

Amid the highly industrialized, export-focused food system of the Canadian prairies, some farmers and consumers are turning to localized agriculture as an alternative—they are “going local”. Despite farmers’ obvious importance to the food system, surprisingly little research has examined their motivations and reasons for localization. To date, most local food scholarship in North America has focused on either consumers’ motivations to buy local or the systemic aspects of local food, such as regulations, infrastructure, and marketing arrangements. Existing research suggests that (...) local food systems are supported by consumers’ rejection of the industrial paradigm and desire to connect with their food and its source. But what drives farmers to localize, particularly when export-focused production is firmly entrenched as the status quo? Based on interviews and focus groups with 60 farmers, processors, policy experts, and retailers in the Canadian prairie province of Saskatchewan, this paper examines local food systems from the producer perspective in a rural context of high industrialization and geographical dispersion. We examine what motivates farmers to produce for local markets, and what forces they must resist to do so. The findings indicate that farmers’ main motivations for localization are political and social in nature, and stem from a critique of the dominant neoliberal agri-food system. We map farmers’ agential responses to this dominant system on a spectrum that ranges from acceptance of a neoliberal “feed the world” ideology to promotion of food sovereignty. Drawing on farmers’ perspectives, our findings question the straightforward equation of local food with environmental sustainability and also challenge neoliberal economic assumptions of “scaling up”.

The strong sensorimotor account of perception gives self-induced movements two constitutive roles in explaining visual consciousness. The first says that self-induced movements are vehicles of visual awareness, and for this reason consciousness ‘does not happen in the brain only’. The second says that the phenomenal nature of visual experiences is consists in the action-directing content of vision. In response I suggest, first, that the sense in which visual awareness is active should be explained by appeal to the role of attention (...) in visual consciousness, rather than self-induced movements; and second, that the sense in which perceptual consciousness does not happen in the brain only should be explained by appeal to the relational nature of perceptual consciousness, appeal to which also shows why links with action cannot exhaust phenomenal content.

One of the problems we face in many-valued logic is the difficulty of capturing the intuitive meaning of the connectives introduced through truth tables. At the same time, however, some logics have nice ways to capture the intended meaning of connectives easily, such as four-valued logic studied by Belnap and Dunn. Inspired by Dunn’s discovery, we first describe a mechanical procedure, in expansions of Belnap-Dunn logic, to obtain truth conditions in terms of the behavior of the Truth and the False, (...) which gives us intuitive readings of connectives, out of truth tables. Then, we revisit the notion of functional completeness, which is one of the key notions in many-valued logic, in view of Dunn’s idea. More concretely, we introduce a generalized notion of functional completeness which naturally arises in the spirit of Dunn’s idea, and prove some fundamental results corresponding to the classical results proved by Post and Słupecki.

What if you woke up one morning and found you'd acquired another self--a double who was almost you and yet not you at all? What if that double shared many of your preoccupations but, in a twisted, upside-down way, furthered the very causes you'd devoted your life to fighting against? Not long ago, the celebrated activist and public intellectual Naomi Klein had just such an experience--she was confronted with a doppelganger whose views she found abhorrent but whose name and (...) public persona were sufficiently similar to her own that many people got confused about who was who. Destabilized, she lost her bearings, until she began to understand the experience as one manifestation of a strangeness many of us have come to know but struggle to define: AI-generated text is blurring the line between genuine and spurious communication; New Age wellness entrepreneurs turned anti-vaxxers are scrambling familiar political allegiances of left and right; and liberal democracies are teetering on the edge of absurdist authoritarianism, even as the oceans rise. Under such conditions, reality itself seems to have become unmoored. Is there a cure for our moment of collective vertigo? Naomi Klein is one of our most trenchant and influential social critics, an essential analyst of what branding, austerity, and climate profiteering have done to our societies and souls. Here she turns her gaze inward to our psychic landscapes, and outward to the possibilities for building hope amid intersecting economic, medical, and political crises. With the assistance of Sigmund Freud, Jordan Peele, Alfred Hitchcock, and bell hooks, among other accomplices, Klein uses wry humor and a keen sense of the ridiculous to face the strange doubles that haunt us--and that have come to feel as intimate and proximate as a warped reflection in the mirror. Combining comic memoir with chilling reportage and cobweb-clearing analysis, Klein seeks to smash that mirror and chart a path beyond despair. Doppelganger asks: What do we neglect as we polish and perfect our digital reflections? Is it possible to dispose of our doubles and overcome the pathologies of a culture of multiplication? Can we create a politics of collective care and undertake a true reckoning with historical crimes? The result is a revelatory treatment of the way many of us think and feel now--and an intellectual adventure story for our times. (shrink)

When covering traumatic events, novice journalists frequently face situations they are rarely prepared to resolve. This paper highlights ethical dilemmas faced by journalists who participated in a focus group exploring the news media's trauma coverage. Major themes included professional obligations versus ethical responsibilities, journalists' perceived status and roles, permissible harms, and inexperience. Instructional classroom simulations based on experiential learning theory can bridge the gap between the theory of ethical trauma reporting and realities journalists face when covering events that are often (...) chaotic and unpredictable by their very nature. A simulation outline that can be used by journalism instructors is provided. (shrink)

Der Aufsatz betrachtet die Geschichte und Praxis des Devising als ein Feld, um die Dynamik zwischen der Gewalt der Entscheidungsfindung und dem Potenzial für Kollektivität und Dissoziation zu untersuchen. Insbesondere beleuchtet dieser Artikel die Tradition des devised theatre, wie sie im Gefolge der Theater- und Performancegruppen der 1960er Jahre entstanden ist, die Kollektivität als politische Ideologie in den Vordergrund stellten. Ausgehend von den jüngsten partizipatorischen Performances des New Yorker Künstlerduos 600 HIGHWAYMEN im Rahmen des Tryptichons A Thousand Ways wird der (...) Begriff devised acts verwendet, um Facetten der Intervention und Entscheidungsfindung zu beschreiben. Der Aufsatz stellt dabei die Frage, wie die Kräfte der Gewalt durch devising transformiert werden können. Ausgehend von der Behauptung der US-amerikanischen Theaterregisseurin Anne Bogart, dass Entscheidungen eine generative Kraft der Gewalt hervorbringen können (2001, S. 45ff.), schaut dieser Beitrag auf Momente dieser „notwendigen Gewalt“ (ebd., S. 46), die sich nicht aus dem Prozess des Theatermachens und der Performance herauslösen lassen.

This paper clarifies several sources of the epistemological confusion that currently characterize the field of clinical psychology. Using a constructivist framework, it is argued that much of this confusion can be traced to a traditional failure to distinguish among levels of analysis when evaluating and comparing clinical psychology theories. By recognizing certain distinctions among levels of analysis, it becomes clear that efforts to provide epistemological legitimacy for clinical psychology theories have often conflated not only theories with epistemology, but also epistemologies (...) that reside at different levels of analysis. Recognition of these distinctions also permits a more precise definition of the role for which the received view of a natural science epistemology and hermeneutics are competing. This role should be defined as a "superordinate" epistemology. It is demonstrated how this concept provides some of the terms necessary for settling the debate between advocates of the received view and advocates of hermeneutics. 2012 APA, all rights reserved).

This note offers a non-deterministic semantics for mbC1, introduced by Janusz Ciuciura, and establishes soundness and completeness results with respect to the Hilbert-style proof system. Moreover, based on the new semantics, we briefly discuss an unexplored variant of mbC1 which has a contra-classical flavor.

The role of motherhood was attenuated over the second half of the twentieth century, by literal and metaphorical factors: Privileged women gained control over their reproduction and developed non-mothering life priorities; government and society became less nurturing in public ideals; projects of spontaneous speciation began in biology; the environment became unsustaining. In addition, feminist criticism resulted in greater individuation between the persons of mothers and their children. With these changes, the role of motherhood lacks a positive identity, culturally and psychically. (...) Extending a literary character, I suggest that mothers consider an attenuated internal identity, based on their unique biological relationships to their children. This would afford a more positive self-identity, as well as a pragmatic solution to demands made by present “middleman” roles for mothers to procure expert child enculturation care, in addition to their “second shifts.”.

Discussive logic was introduced by Jaskowski as a logic of discussion. In this note we show that some natural translation-based formalizations of discussive logic in modal logic do not yield a paraconsistent logic but rather classical logic. Some alternative modal formalizations of discussive logic that avoid the collapse into classical logic are put forward.

Change of logic is typically taken as requiring that the meanings of the connectives change too. As a result, it has been argued that legitimate rivalry between logics is under threat. This is, in a nutshell, the meaning‐variance argument, traditionally attributed to Quine. In this paper, we present a semantic framework that allows us to resist the meaning‐variance claim for an important class of systems: classical logic, the logic of paradox and strong Kleene logic. The major feature of the semantics (...) is that the connectives have the same meanings in these systems, so that the meaning‐variance argument is straightforwardly blocked. We discuss the effects of this semantics for two uses of the argument of meaning variance, and also consider its impact on related issues. (shrink)

Naomi Zack brings us an indispensable work in the ethics of race through an inquiry into the history of moral philosophy. The Ethics and Mores of Race: Equality after the History of Philosophy enters into a web of ideas, ethics, and morals that untangle our evolving ideas of racial equality straight into the twenty-first century.

In this paper, we generalize the ordered-pair semantics advanced by Matthew Clemens for the Logic of Paradox to n-tuple semantics, for each fixed n. Moreover, we show that the resulting semantics can accommodate not only LP, but also classical logic as well as strong Kleene logic depending on the set of designated values that one chooses. Building on the technical observations, we offer intuitively plausible readings for the semantics, and we also discuss some weaknesses of the original intuitive reading advanced (...) by Clemens.

We observe that Jc Beall’s shrieking and shrugging strategy gives us an opportunity to reflect on the Australian plan for negation in FDE, a basic subclassical logic that is used in Beall’s argument for subclassical logics. An implication of our observation is applied to a recent defense of the Australian plan for negation by Francesco Berto and Greg Restall.

Grounding talk has become increasingly familiar in contemporary philosophical discussion. Most discussants of grounding think that grounding talk is useful, intelligible, and accurately describes metaphysical reality. Call themrealistsabout grounding. Some dissenters reject grounding talk on the grounds that it is unintelligible, or unmotivated. They would prefer to eliminate grounding talk from philosophy, so we can call themeliminitivistsabout grounding. This paper outlines a new position in the debate about grounding, defending the view that grounding talk is (or at least can be) (...) intelligible and useful. Grounding talk does not, however, provide a literal and veridical description of mind-independent metaphysical reality. This (non-eliminative)irrealismabout grounding treads a path between realism and eliminativism. (shrink)

To answer the question of what difference the philosophy of history makes to the philosophy of law this paper begins by calling attention to the way that Ronald Dworkin's interpretive theory of law is supposed to upend legal positivism. My analysis shows how divergent theories about what law and the basis of legal authority is are supported by divergent points of view about what concepts are, how they operate within social practices, and how we might best give account of such (...) meanings. Such issues are widely debated in the philosophy of history but are often overlooked in jurisprudential circles. When the legal positivist approach to meanings is contrasted with Dworkin's interpretivism it is clear that what is needed is an alternative to both, in the form of what we might call "historical meanings" and "historical interpretation". While Dworkin's interpretivism gets it right that legal positivism is an inadequate philosophy of law to the extent that it is committed to a "criterial semantics" view of concepts, this paper argues that post-positivism in the philosophy of law need not entail a normative jurisprudence, as Dworkin would have it.

Socrates was not a moral philosopher. Instead he was a theorist who showed how human desire and human knowledge complement one another in the pursuit of human happiness. His theory allowed him to demonstrate that actions and objects have no value other than that which they derive from their employment by individuals who, inevitably, desire their own happiness and have the knowledge to use actions and objects as a means for its attainment. The result is a naturalised, practical, and demystified (...) account of good and bad, and right and wrong. Professor Reshotko presents a freshly envisioned Socratic theory residing at the intersection of the philosophy of mind and ethics. It makes an important contribution to the study of the Platonic dialogues and will also interest all scholars of ethics and moral psychology. (shrink)

Sometime around their first birthday most infants begin to engage in relatively sustained bouts of attending together with their caretakers to objects in their environment. By the age of 18 months, on most accounts, they are engaging in full-blown episodes of joint attention. As developmental psychologists (usually) use the term, for such joint attention to be in play, it is not sufficient that the infant and the adult are in fact attending to the same object, nor that the one’s attention (...) cause the other’s. The latter can and does happen much earlier, whenever the adult follows the baby’s gaze and homes in on the same object as the baby is attending to; or, from the age of six months, when babies begin to follow the gaze of an adult. We have the relevant sense of joint attention in play only when the fact that both child and adult are attending to the same object is, to use Sperber and Wilson’s (1986) phrase, ‘mutually manifest’. Psychologists sometimes speak of such jointness as a case of attention being ‘shared’ by infant and adult, or of a ‘meeting of minds’ between infant and adult, all phrases intended to capture the idea that when joint attention occurs everything about the fact that both subjects are attending to the same object is out in the open, manifest to both participants.

We investigate the notion of classical negation from a non-classical perspective. In particular, one aim is to determine what classical negation amounts to in a paracomplete and paraconsistent four-valued setting. We first give a general semantic characterization of classical negation and then consider an axiomatic expansion BD+ of four-valued Belnap–Dunn logic by classical negation. We show the expansion complete and maximal. Finally, we compare BD+ to some related systems found in the literature, specifically a four-valued modal logic of Béziau and (...) the logic of classical implication and a paraconsistent de Morgan negation of Zaitsev.

This introductory paper sets out a framework for approaching some of the claims about the second person made by the papers collected in the special edition of Philosophical Explorations on The Second Person . It does so by putting centre stage the notion of a ‘bipolar second person relation’, and examining ways of giving it substance suggested by the authors of these papers. In particular, it focuses on claims made in these papers about the existence and/or nature of second person (...) thought, second person reasons for action and second person reasons for belief and about possible connections among thought-theoretical, ethical and epistemological issues and debates in this area.

There is a relatively recent trend in treating negation as a modal operator. One such reason is that doing so provides a uniform semantics for the negations of a wide variety of logics and arguably speaks to a longstanding challenge of Quine put to non-classical logics. One might be tempted to draw the conclusion that negation is a modal operator, a claim Francesco Berto, 761–793, 2015) defends at length in a recent paper. According to one such modal account, the negation (...) of a sentence is true at a world x just in case all the worlds at which the sentence is true are incompatible with x. Incompatibility is taken to be the key notion in the account, and what minimal properties a negation has comes down to which minimal conditions incompatibility satisfies. Our aims in this paper are twofold. First, we wish to point out problems for the modal account that make us question its tenability on a fundamental level. Second, in its place we propose an alternative, non-modal, account of negation as a contradictory-forming operator that we argue is superior to, and more natural than, the modal account. (shrink)

Naomi Scheman argues that the concerns of philosophy emerge not from the universal human condition but from conditions of privilege. Her books represents a powerful challenge to the notion that gender makes no difference in the construction of philosophical reasoning. At the same time, it criticizes the narrow focus of most feminist theorizing and calls for a more inclusive form of inquiry.
