It is shown that the implicational fragment of Anderson and Belnap's R, i.e. Church's weak implicational calculus, is not uniquely characterized by MP (modus ponens), US (uniform substitution), and WDT (Church's weak deduction theorem). It is also shown that no unique logic is characterized by these, but that the addition of further rules results in the implicational fragment of R. A similar result for E is mentioned.

In this 2020 AFHVS Presidential Address, Molly Anderson suggests that we must push beyond the boundaries imposed by our training, institutional reward systems, political system and comfort zones in order to solve global challenges. She lists five challenges facing those who are trying to build more sustainable food systems: overcoming the technocratic and productivist approach of industrial agriculture, avoiding future pandemics, restoring degraded and depleted systems and resources, remaining united as a movement while creating collaborations with other movements, and (...) redistributing power across food system actors so that everyone can realize their human rights, including the right to food. She describes three ways that she has found to be effective in pushing beyond boundaries: international collaborations, interactions with global social movements, and anti-racist work. She links these “moments” of opportunity back to the five challenges, and concludes with advice to young scholars. (shrink)

The work of Michèle Le Dœuff creatively disrupts established notions of what philosophy might be. Far from being a discipline about the leader and the disciple, a hierarchy of knowledge and paternalism, Le Dœuff proposes a philosophy of dialogue and friendship. The conversations in this book explore how this philosophy can be enacted and explored, and show how openness and generosity can be the starting point of truly rigorous thinking. Introduced and curated by the late philosopher, Pamela Sue Anderson, (...) In Dialogue with Michèle Le Dœuff explores themes like contemporary feminism, joy in philosophy, memory, the significance of friendship to thinking and a key Le Dœuffian concept, the imaginary. Le Dœuff's interlocutors, including Penelope Deutscher, Elizabeth Fallaize and Meenda Dhanda, are some of the most significant thinkers in the fields of feminism and continental thought and provide insights and ways into considering philosophy as a profoundly dialogical exercise.

Trata-se de mostrar como a “colisão” da lógica com sua aplicação, no cenário do Tractatus Logico-Philosophicus de Wittgenstein, pode ser enxergada a partir do problema da incompatibilidade das cores. Exploraremos algumas soluções nos moldes tractarianos, verificando em que medida elas não satisfazem algumas exigências da obra. Também apresentaremos uma tentativa de solução do próprio Wittgenstein para o problema, mostrando como o filósofo percebe que tal solução não é satisfatória.

There are few participants in academic or policy debates over prostitution who would disagree that steps should be taken to improve conditions for those working in prostitution; so Moen1 is in good and plentiful company with respect to his recommendations.I will focus here on the analysis leading up to his conclusions, and with whether it helps us understand why prostitution is so commonly harmful and what it would take to mitigate those harms.i On these matters I am dubious. The question (...) of whether or not prostitution is harmful would seem, manifestly, to be an empirical question, rather than a philosophical issue. I take it that Moen's aim is to clarify the evaluative task, and then to evaluate the arguments that can be made to show prostitution is harmful—tasks which philosophers can responsibly engage in. But I would suggest that Moen's approach to this particular subject oversimplifies it by abstracting away from key facts about the context in which prostitution takes place, and thus that it does not offer as strong a case for normalising prostitution as he hopes.The basic thesis of Moen's essay is that if casual sex is harmless , then the sale of casual sexual services for money is also harmless, or at ….

This article investigates the potential of fMRI to test assumptions about different components in models of complex cognitive tasks. If the components of a model can be associated with specific brain regions, one can make predictions for the temporal course of the BOLD response in these regions. An event‐locked procedure is described for dealing with temporal variability and bringing model runs and individual data trials into alignment. Statistical methods for testing the model are described that deal with the scan‐to‐scan correlations (...) in the errors of measurement of the BOLD signal. This approach is illustrated using a “sacrificial” ACT‐R model that involves mapping 6 modules onto 6 brain regions in an experiment from concerned with equation solving. The model's visual encoding predicted the BOLD response in the fusiform gyrus, its controlled retrieval predicted the BOLD response in the lateral inferior prefrontal cortex, and its subgoal setting predicted the BOLD response in the anterior cingulate cortex. On the other hand, its motor programming failed to predict anticipatory activation in the motor cortex, its representational changes failed to predicted the pattern of activity in the posterior parietal cortex, and its procedural component failed to predict an initial spike in caudate. The results illustrate the power of such data to direct the development of a theory of complex problem solving, both at the level of a specific task model as well as at the level of the cognitive architecture.

This essay introduces the massive redeployment hypothesis, an account of the functional organization of the brain that centrally features the fact that brain areas are typically employed to support numerous functions. The central contribution of the essay is to outline a middle course between strict localization on the one hand, and holism on the other, in such a way as to account for the supporting data on both sides of the argument. The massive redeployment hypothesis is supported by case studies (...) of redeployment, and compared and contrasted with other theories of the localization of function. (shrink)

This article considers whether there is a specific demand for migrant domestic workers in the UK, or for workers with particular characteristics that in theory could be met by citizens. It discusses how immigration status can make it easier not only to recruit domestic workers, but also to retain them. `Foreignness' may also make the management of the employment relation easier with employers anxious to discover a coincidence of interest with the worker. Employers are not only looking for generic `foreignness' (...) however, but typically also seek particular nationalities or ethnicities of worker, which can raise difficulties for agencies who are not allowed to discriminate on the basis of `race'.

In the Foundations of Mathematics, Ramsey attempted to amend Principia Mathematica’s logicism to meet serious objections raised against it. While Ramsey’s paper is well known, some questions concerning Ramsey’s motivations to write it and its reception still remain. This paper considers these questions afresh. First, an account is provided for why Ramsey decided to work on his paper instead of simply accepting Wittgenstein’s account of mathematics as presented in the Tractatus. Secondly, evidence is given supporting that Wittgenstein was not moved (...) by Ramsey’s objection against the Tractarian account of arithmetic, and a suggestion is made to explain why Wittgenstein reconsidered Ramsey’s account in the early thirties on several occasions. Finally, a reading is formulated to understand the basis on which Wittgenstein argues against Ramsey’s definition of identity in his 1927 letter to Ramsey. (shrink)

La investigación ecológica a largo plazo (Long Term Ecological Research, LTER) maneja problemas que abarcan décadas o plazos más largos. El programa y su nombre formal comenzaron en Estados Unidos en 1980. Si bien los estudios y observaciones a largo plazo comenzaron tempranamente en 1400 y 1800 en Asia y Europa, respectivamente, el enfoque a largo plazo no se formalizó sino hasta el establecimiento de los programas de investigación ecológica de largo plazo en Estados Unidos. Estos programas han permitido experimentos (...) a nivel de ecosistemas y comparaciones entre sitios que condujeron a una mejor comprensión de la estructura y funcionamiento de la biosfera. El enfoque ecosistémico holístico de esta iniciativa permite también la incorporación de la dimensión humana en la ecología, y recientemente ha dado lugar al nuevo concepto de investigación socio-ecológica de largo plazo (LTSER). Hoy los programas de investigación socio-ecológica a largo plazo existen en por lo menos 32 países (esto es, los miembros de la Red Internacional de Investigación Ecológica a Largo Plazo o ILTER (International Long Term Ecological Research). Sin embargo, la consolidación de la red internacional dentro del paradigma de investigación socio-ecológica a largo plazo todavía requiere: (1) inclusión de algunas regiones remotas del mundo que aún están poco representadas, como el suroeste de América del Sur; (2) modificaciones en el tipo de investigación realizado, tales como la integración de las ciencias sociales y naturales con las humanidades y la ética, y (3) la incorporación de las conclusiones y resultados dentro de los procesos sociales y políticos. En este contexto, la naciente red de investigación socio-ecológica a largo plazo en Chile, que se extiende en el rango latitudinal más largo de bosque templado en el Hemisferio Sur, agrega una nueva región remota a las investigaciones ecológicas de largo plazo que había sido pasada por alto anteriormente. Además, la colaboración con la Universidad de North Texas y otros asociados internacionales ayuda a desarrollar un enfoque interdisciplinario para integrar las ciencias ecológicas y la filosofía ambiental, junto con los conocimientos ecológicos tradicionales, la educación informal y formal, la política, las humanidades, los procesos socio-políticos y la conservación biocultural.

In 1958 William L. Langer, in a well-known presidential address to the American Historical Association, declared the informed use of psychoanalytic depth psychology as "the next assignment" for professional historians. _Psychoanalysis and History_, volume 31 of _The Annual of Psychoanalysis_, examines the degree to which Langer's directive has been realized in the intervening 45 years. Section I makes the case for psychobiography in the lives of historical figures and exemplifies this perspective with analytically informed studies of the art of Wassily (...) Kandinsky; the films of Stanley Kubrick; and the anti-Semitism of Adolf Hitler. Section II reviews Freud's own psychohistorical contributions and then considers the relevance to historical inquiry of the more recent perspectives of Winnicott, Kernberg, and Kohut. Section III explores an intriguing tributary of psychobiographical inquiry: the impact of the biographer's own subjectivity on his or her work. Section IV turns to a topic of perennial interest: the psychobiographical study of American presidents. Section V turns to the special challenges of applying psychoanalysis to topics of religious history and includes topical studies of religious figures as disparate as the 15th century Asian Drukpa Kunley and Osama bin Laden. Section VI focuses on the recent extension of psychohistorical inquiry to groups of people and to cultural phenomena more generally: an investigation of the youth movement in pre-Nazi Germany; consideration of how societies, no less than individuals, reenact and work through traumas over time; and an outline of the role of analysis in constructing a depth-psychological "social psychology" of use to historians. These papers, no less than those that precede them, are compelling testimony to the claim with which editors James William Anderson and Jerome A. Winer begin the volume, to wit, that "Psychoanalysis would seem to be a resource indispensable to the study of history.". (shrink)

What is terrorism? What ought we to do about it? And why is it wrong? We think we have clear answers to these questions. But acts of violence, like U.S. drone strikes that indiscriminately kill civilians, and mass shootings that become terrorist attacks when suspects are identified as Muslim, suggest that definitions of terrorism are always contested. In Genealogies of Terrorism, Verena Erlenbusch-Anderson rejects attempts to define what terrorism is in favor of a historico-philosophical investigation into the conditions under (...) which uses of this contested term become meaningful. The result is a powerful critique of the power relations that shape how we understand and theorize political violence. -/- Tracing discourses and practices of terrorism from the French Revolution to late imperial Russia, colonized Algeria, and the post-9/11 United States, Erlenbusch-Anderson examines what we do when we name something terrorism. She offers an important corrective to attempts to develop universal definitions that assure semantic consistency and provide normative certainty, showing that terrorism means many different things and serves a wide range of political purposes. In the tradition of Michel Foucault’s genealogies, Erlenbusch-Anderson excavates the history of conceptual and practical uses of terrorism and maps the historically contingent political and material conditions that shape their emergence. She analyzes the power relations that make different modes of understanding terrorism possible and reveals their complicity in justifying the exercise of sovereign power in the name of defending the nation, class, or humanity against the terrorist enemy. Offering an engaged critique of terrorism and the mechanisms of social and political exclusion that it enables, Genealogies of Terrorism is an empirically grounded and philosophically rigorous critical history with important political implications.

A key question in understanding microtubule dynamics is how GTP hydrolysis leads to catastrophe, the switch from slow growth to rapid shrinkage. We first provide a review of the experimental and modeling literature, and then present a new model of microtubule dynamics. We demonstrate that vectorial, random, and coupled hydrolysis mechanisms are not consistent with the dependence of catastrophe on tubulin concentration and show that, although single-protofilament models can explain many features of dynamics, they do not describe catastrophe as a (...) multistep process. Finally, we present a new combined (coupled plus random hydrolysis) multiple-protofilament model that is a simple, analytically solvable generalization of a single-protofilament model. This model accounts for the observed lifetimes of growing microtubules, the delay to catastrophe following dilution and describes catastrophe as a multistep process. (shrink)

Moral judgments about an agent's behavior are enmeshed with inferences about the agent's mind. Folk psychology—the system that enables such inferences—therefore lies at the heart of moral judgment. We examine three related folk-psychological concepts that together shape people's judgments of blame: intentionality, choice, and free will. We discuss people's understanding and use of these concepts, address recent findings that challenge the autonomous role of these concepts in moral judgment, and conclude that choice is the fundamental concept of the three, defining (...) the core of folk psychology in moral judgment.

In barely the space of one generation, Athens was transformed from a conventional city-state into something completely new--a region-state on a scale previously unthinkable. This book sets out to answer a seemingly simple question: How and when did the Athenian state attain the anomalous size that gave it such influence in Greek politics and culture in the classical period? Many scholars argue that Athens's incorporation of Attica was a gradual development, largely completed some two hundred years before the classical era. (...) Anderson, however, suggests that it is not until the late sixth century that we see the first systematic attempts by the Athenian polis to integrate all of Attica. Anderson first takes issue with the prevailing view of Cleisthenes' landmark political reforms of 508-7 b.c., arguing that they were animated by a more comprehensive vision of regional political community in Attica. The Athenians' strengthened the state by establishing institutional mechanisms that would allow inhabitants of the Attic periphery to participate as never before in the life of the center. The creation of a suitable physical setting for the new order was accompanied by religious, military, and symbolic innovations. Regional participation in Athenian affairs was stimulated by encouraging the Attic populace to imagine themselves, for the first time ever, as members of a single, like-minded, self-governing political community.

Since the publication of the Remarks on the Foundations of Mathematics, Wittgenstein’s interpreters have endeavored to reconcile his general constructivist/anti-realist attitude towards mathematics with his confessed anti-revisionary philosophy. In this article, the author revisits the issue and presents a solution. The basic idea consists in exploring the fact that the so-called “non-constructive results” could be interpreted so that they do not appear non-constructive at all. The author substantiates this solution by showing how the translation of mathematical results, given by the (...) possibility of translation between logics, can be seen as a tool for partially implementing the solution Wittgenstein had in mind.

Allograft shortage is a formidable obstacle in organ transplantation. Xenotransplantation, the interspecies transplantation of cells, tissues, and organs, or ex vivo interspecies exchange between cells, tissues, and organs is a frequently suggested alternative to this allograft shortage. As xenotransplantation steadily improves into a viable allotransplantation alternative, several bioethical considerations coalesce. Such considerations include the Helsinki declaration’s guarantee of patients’ rights to privacy; political red tape that may select for undermined socioeconomic groups as the first recipients of xenografts; industry incentives in (...) xenotransplantation investments; conflicts of interest when a clinician supervises a patient as a research subject; the psychosocial impact of transplantation on the xenograft recipient, and the rights of animals. This review illuminates these issues through a conglomeration of expert opinion and relevant experimental studies. (shrink)

At least since the seminal work of the (US) National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research in the 1970s, a fundamental distinction between research and practice has underwritten both conceptual work in research ethics and regulations governing research involving human subjects. Notwithstanding its undoubted historical importance, I believe the distinction is problematic because it misrepresents clinical inquiry. In this essay, I aim to clarify the character of clinical inquiry by identifying crucial contextual constraints on (...) justification constitutive of clinical science. This analysis shows that, from an epistemological point of view, clinical research and clinical practice are not sharply distinct but intimately intertwined. This result is important in its own right—an enriched understanding of the epistemology of clinical research is valuable in and of itself. But this result is also important because it has profound implications for the ethics of human subjects research. (shrink)

“The physics of representation” aims to define the word “representation” as used in the neurosciences, argue that such representations as described in neuroscience are related to and usefully illuminated by the representations generated by modern neural networks, and establish that these entities are “representations in good standing”. We suggest that Poldrack succeeds in, exposes some tensions between the broad use of the term in neuroscience and the narrower class of entities that he identifies in the end, and between the meaning (...) of “representation” in neuroscience and in psychology in, and fails in. This results in some hard choices: give up on the broad scope of the term in neuroscience or continue to embrace the broad, psychologically inflected sense of the term, and deny the entities generated by neural nets are representations in the relevant sense.

When citizens call the police to report a problem with another, they need to not only characterize the problematic action/event, but they must position themselves in relation to the complained-about person. This conversational work of positioning self, and describing the other's actions, is delicate business when the complained-about person is connected to the caller. Different constructions of the other and the problem affect whether callers get the help they are seeking. At the same time, alternate constructions offer different pictures of (...) the other's blameworthiness and self's contribution to the problem. In this study we analyze citizen calls to the police in which callers have a dilemma: they have a problem with another that they want remedied but the problem occurs in a situation where involving the police is regarded as unreasonable. Past research on calls to the police, and studies about how people position their own and others' actions in sensitive situations are described. Then the materials and interpretive method are explained. The heart of the article is a description of four relational positioning strategies. Strategies include: generic reference terms; `friend' to imply a non-sexual relationship; ex-prefaces; and agent-less problems. The conclusion considers where else the dilemma will be found and highlights distinctive features of the rhetorical discursive perspective developed in the article. (shrink)

The traditional understanding of coercion as exemplified by the use of force and violence to constrain the actions of agents has been challenged by theories that describe coercion instead in terms of the pressure it puts on some agents to act or refrain from acting. Building on earlier work defending the traditional understanding and rejecting the ‘pressure’ accounts of coercion, I argue in this paper that the traditional understanding of coercion, which I dub ‘coercion as enforcement’, provides a helpful analytic (...) tool for identifying coercion in peripheral cases, and thereby supporting the theoretical implications that are supposed to follow from the claim that someone has been coerced. In particular I analyze the coerciveness of the practices of credit-card issuers and institutions of higher education, and the demands by Greece’s creditors that the Greek government institute fiscal austerity, or else leave the European Monetary Union.
