The inference systems proposed for solving SAT are unsound for solving MaxSAT and MinSAT, because they preserve satisfiability but not the minimum and maximum number of clauses that can be falsified, respectively. To address this problem, we first define a clause tableau calculus for MaxSAT and prove its soundness and completeness. We then define a clause tableau calculus for MinSAT and also prove its soundness and completeness. Finally, we define a complete clause tableau calculus for solving both MaxSAT and MinSAT, (...) in that the minimum number of generated empty clauses provides an optimal MaxSAT solution and the maximum number provides an optimal MinSAT solution.

The logical calculus for SAT are not valid for MaxSAT and MinSAT because they preserve satisfiability but not the number of unsatisfied clauses. To overcome this drawback, a MaxSAT resolution rule preserving the number of unsatisfied clauses was defined in the literature. This rule is complete for MaxSAT when it is applied following a certain strategy. In this paper we first prove that the MaxSAT resolution rule also provides a complete calculus for MinSAT if it is applied following the strategy (...) proposed here. We then describe an exact variable elimination algorithm for MinSAT based on that rule. Finally, we show how the results for Boolean MinSAT can be extended to solve the MinSAT problem of the multiple-valued clausal forms known as signed conjunctive normal form formulas. (shrink)

There is an inconsistency in the ways that doctors make clinical decisions regarding the treatment of babies born extremely prematurely. Many experts now recommend that clinical decisions about the treatment of such babies be individualized and consider many different factors. Nevertheless, many policies and practices throughout Europe and North America still appear to base decisions on gestational age alone or on gestational age as the primary factor that determines whether doctors recommend or even offer life-sustaining neonatal intensive care treatment. These (...) policies are well intentioned. They aim to guide doctors and parents to make decisions that are best for the baby. That is an ethically appropriate goal. But in relying so heavily on gestational age, such policies may actually do the babies a disservice by denying some babies treatment that might be beneficial and lead to intact survival. In this paper, we argue that such policies are unjust to premature babies and ought to be abolished. In their place, we propose individualized treatment decisions for premature babies. This would treat premature babies as we treat all other patients, with clinical decisions based on an individualized estimation of likelihood that treatment would be beneficial. (shrink)

O objetivo deste texto é analisar os argumentos de Jean-François Lyotard a respeito do filosofar enquanto transformação na obra intitulada Por que filosofar? Lyotard publicou esse livro em 1989, constituído por quatro conferências proferidas em 1964 intituladas i. Por que desejar?, ii. Filosofia e Origem; iii. Sobre a palavra filosófica e iv. Sobre filosofia e ação, durante a fase em que foi marxista crítico nos anos 60 e 70. Em 1986 Lyotard afirma que foi atacado injustamente por ter mudado sua (...) posição política a partir da publicação de 1971, a qual marca a ruptura em sua obra, intitulada Discurso, Figura, onde analisa o que é a figura e o que é o figural/figurativo.

Learning from the Inside-Out: Child Development and School Choice is the first book of its kind to marry child development, educational psychology, neuroscience, and pedagogy. This book goes beyond the now banal conversation of differentiating students based upon gender, race, and class. This book is about the cognitive and social needs of students throughout the developmental span and how to identify schools that meet those needs. In essence, this book rejects the one-size-fits-all discourse of education reform in favor of a (...) focus on individualized educational decision-making. Learning from the Inside-Out acknowledges that contrary to the popular saying, good teaching is not good teaching. What one student needs in a teacher, classroom environment or curricula is not necessarily what another student might need despite demographic similarities. After reading this book, parents and teachers will be empowered and informed when making decisions about how best to educate children. (shrink)

This article investigates the relationship between emotional sharing and the extended mind thesis. We argue that shared emotions are socially extended emotions that involve a specific type of constitutive integration between the participating individuals’ emotional experiences. We start by distinguishing two claims, the Environmentally Extended Emotion Thesis and the Socially Extended Emotion Thesis. We then critically discuss some recent influential proposals about the nature of shared emotions. Finally, in Sect. 3, we motivate two conditions that an account of shared emotions (...) ought to accommodate: Reciprocal Other-awareness and Integration. Consideration of and discussion of relational accounts of joint attention lead us to the proposal that a construal of socially extended emotions in terms of a constitutive integration of the participating individuals’ experiences is more promising than proposals that simply appeal to various forms of social situatedness, embeddedness, or scaffolding.

The experimental interventions that provide evidence of causal relations are notably similar to those that provide evidence of constitutive relevance relations. In the first two sections, I show that this similarity creates a tension: there is an inconsistent triad between Woodward’s popular interventionist theory of causation, Craver’s mutual manipulability account of constitutive relevance in mechanisms, and a variety of arguments for the incoherence of inter-level causation. I argue for an interpretation of the views in which the tension is merely apparent. (...) I propose to explain inter-level relations without inter-level causation by appealing to the notion of fat-handed interventions, and an argument against inter-level causation which dissolves the problem.

This collection highlights the new trend away from rationalism and toward empiricism in the epistemology of modality. Accordingly, the book represents a wide range of positions on the empirical sources of modal knowledge. Readers will find an introduction that surveys the field and provides a brief overview of the work, which progresses from empirically-sensitive rationalist accounts to fully empiricist accounts of modal knowledge. Early chapters focus on challenges to rationalist theories, essence-based approaches to modal knowledge, and the prospects for naturalizing (...) modal epistemology. The middle chapters present positive accounts that reject rationalism, but which stop short of advocating exclusive appeal to empirical sources of modal knowledge. The final chapters mark a transition toward exclusive reliance on empirical sources of modal knowledge. They explore ways of making similarity-based, analogical, inductive, and abductive arguments for modal claims based on empirical information. Modal epistemology is coming into its own as a field, and this book has the potential to anchor a new research agenda. (shrink)

Replicability is widely taken to ground the epistemic authority of science. However, in recent years, important published findings in the social, behavioral, and biomedical sciences have failed to replicate, suggesting that these fields are facing a “replicability crisis.” For philosophers, the crisis should not be taken as bad news but as an opportunity to do work on several fronts, including conceptual analysis, history and philosophy of science, research ethics, and social epistemology. This article introduces philosophers to these discussions. First, I (...) discuss precedents and evidence for the crisis. Second, I discuss methodological, statistical, and social-structural factors that have contributed to the crisis. Third, I focus on the philosophical issues raised by the crisis. Finally, I discuss proposed solutions and highlight the gaps that philosophers could focus on. (shrink)

The reward system of science is the priority rule. The first scientist making a new discovery is rewarded with prestige, while second runners get little or nothing. Michael Strevens, following Philip Kitcher, defends this reward system, arguing that it incentivizes an efficient division of cognitive labor. I argue that this assessment depends on strong implicit assumptions about the replicability of findings. I question these assumptions on the basis of metascientific evidence and argue that the priority rule systematically discourages replication. My (...) analysis leads us to qualify Kitcher and Strevens’s contention that a priority-based reward system is normatively desirable for science. (shrink)

This book provides an up to date, high-level exchange on God in a uniquely productive style. Readers witness a contemporary version of a classic debate, as two professional philosophers seek to learn from each other while making their cases for their distinct positions. In their dialogue, Joshua Rasmussen and Felipe Leon examine classical and cutting-edge arguments for and against a theistic explanation of general features of reality. The book also provides original lines of thought based on the authors’ own contributions (...) to the field, and offers a productive and innovative inquiry into on one of the biggest questions people ask: what is the ultimate explanation of things?

. Scientists, for the most part, want to get it right. However, the social structures that govern their work undermine that aim, and this leads to nonreplicable findings in many fields. Because the social structure of science is a decentralized system, it is difficult to intervene. In this article, I discuss how we might do so, focusing on self-corrective-labor schemes. First, I argue that we need to implement a scheme that makes replication work outcome independent, systematic, and sustainable. Second, I (...) use these three criteria to evaluate extant proposals, which place the responsibility for replication on original researchers, consumers of their research, students, or many labs. Third, on the basis of a philosophical analysis of the reward system of science and the benefits of the division of cognitive labor, I propose a scheme that satisfies the criteria better: the professional scheme. This scheme has two main components. First, the scientific community is organized into two groups: discovery researchers, who produce new findings, and confirmation researchers, whose primary function is to do confirmation work. Second, a distinct reward system is established for confirmation researchers so that their career advancement is separated from whether they obtain positive experimental results. (shrink)

Advocates of the self-corrective thesis argue that scientific method will refute false theories and find closer approximations to the truth in the long run. I discuss a contemporary interpretation of this thesis in terms of frequentist statistics in the context of the behavioral sciences. First, I identify experimental replications and systematic aggregation of evidence (meta-analysis) as the self-corrective mechanism. Then, I present a computer simulation study of scientific communities that implement this mechanism to argue that frequentist statistics may converge upon (...) a correct estimate or not depending on the social structure of the community that uses it. Based on this study, I argue that methodological explanations of the “replicability crisis” in psychology are limited and propose an alternative explanation in terms of biases. Finally, I conclude suggesting that scientific self-correction should be understood as an interaction effect between inference methods and social structures. (shrink)

. Este artículo se propone discutir las dificultades que pertenecen al ejercicio de pensarnos en cuanto corporales. Guía de estas reflexiones son los índices heideggerianos sobre la corporalidad humana realizados en Zollikoner Seminare. Dichos seminarios advierten que la actual experiencia de nuestro cuerpo, pese a poder ser estimada como inmediata, se halla mediada por nuestros propios supuestos epocales y se enraiza ya en el pensar ontológico de Occidente. Así, este artículo intentará examinar las aporías filosóficas de tal mediación histórico-epocal, exponiendo (...) la reflexión heideggeriana del cuerpo desde el claro del ser como una respuesta a la idea tradicional de subjetividad fundada en la noción de “mera presencia”.

On a widely held characterization, triadic joint attention is the capacity to perceptually attend to an object or event together with another subject. In the last four decades, research in developmental psychology has provided increasing evidence of the crucial role that this capacity plays in socio-cognitive development, early language acquisition, and the development of perspective-taking. Yet, there is a striking discrepancy between the general agreement that joint attention is critical in various domains, and the lack of theoretical consensus on how (...) to account for it. This paper pursues three interrelated aims: (i) it examines the contrast between reductive and non-reductive views of (triadic) joint attention, by bringing into focus the notion of recursive mindreading; (ii) it assembles, advances, and discusses a number of arguments against reductive views; (iii) finally, in dialogue with some prominent non-reductive views, it outlines the case for a non-reductive view that gives pride of place to the idea that co-attenders relate to one another as a ‘you’.

While most people believe the best possible life they could lead would be an immortal one, so‐called “immortality curmudgeons” disagree. Following Bernard Williams, they argue that, at best, we have no prudential reason to live an immortal life, and at worst, an immortal life would necessarily be bad for creatures like us. In this article, we examine Bernard Williams' seminal argument against the desirability of immortality and the subsequent literature it spawned. We first reconstruct and motivate Williams' somewhat cryptic argument (...) in three parts. After that, we elucidate and motivate the three best (and most influential) counterarguments to Williams' seminal argument. Finally, we review, and critically examine, two further distinct arguments in favor of the anti‐immortality position. (shrink)

Mathematicians routinely pass judgements on mathematical proofs. A proof might be elegant, cumbersome, beautiful, or awkward. Perhaps the highest praise is that a proof is right, that is, that the proof fits the theorem in an optimal way. It is also common to judge that one proof fits better than another, or that a proof does not fit a theorem at all. This paper attempts to clarify the notion of mathematical fit. We suggest six criteria that distinguish proofs as being (...) more or less fitting, and provide examples from several different mathematical fields. (shrink)

The enduring replication crisis in many scientific disciplines casts doubt on the ability of science to estimate effect sizes accurately, and in a wider sense, to self-correct its findings and to produce reliable knowledge. We investigate the merits of a particular countermeasure—replacing null hypothesis significance testing with Bayesian inference—in the context of the meta-analytic aggregation of effect sizes. In particular, we elaborate on the advantages of this Bayesian reform proposal under conditions of publication bias and other methodological imperfections that are (...) typical of experimental research in the behavioral sciences. Moving to Bayesian statistics would not solve the replication crisis single-handedly. However, the move would eliminate important sources of effect size overestimation for the conditions we study.

This essay focuses on the similarities between Nietzsche’s and Carnap’s views on metaphysics, without ignoring their obvious differences. The essay argues that Nietzsche and Carnap endorse but interpret differently an overcoming metametaphysics characterized by the conjunction of the following three claims: an overcoming of metaphysics ought to be performed; this overcoming is to be performed by adopting a method of linguistic analysis that is suspicious of the metaphysical use of language and that interprets such use through a different use of (...) language which aims to avoid metaphysics; and this overcoming contributes to the political task of resisting “diseased” metaphysical practices and promoting “healthy” non-metaphysical practices.

Donald Davidson alcanzó celebridad en el mundo filosófico con la publicación en 1963 de su artículo ¿Acciones, razones y causas¿. En él sostuvo la tesis de que la explicación de una acción mediante razones constituye una forma de explicación causal en la que las razones son entendidas como causa efectiva de la acción. Esta tesis cobró máxima relevancia al interior del contexto intelectual en cuyo seno surgió. Al publicarse el artículo en cuestión, en el mundo anglosajón predominaba la idea de (...) que las razones no eran causa de la acción. Esta idea había sido defendida principalmente por filósofos de orientación wittgensteniana. El presente ensayo aborda algunas de las principales pruebas que se aludieron en defensa de la tesis que sostenía el carácter no causal de las razones, poniéndolas en contraste con los argumentos de los que Davidson se sirve para mostrar la posibilidad de que pueda haber implicaciones lógicas entre determinadas descripciones de eventos, sin que esto impida que tales eventos se relacionen como causa y efecto, dando lugar a lo que en su momento fue ¿y sigue siendo- un original planteamiento filosófico.

This manuscript intends to show some features of the concept “Historical Time” and its link with an idea of acceleration of History in constitutive terms. The Historical Time is used as concept mainly from the XVIII century and correspond to a way of understanding the contemporary World as a moment in which take place a chronology of Time and, along with it, the appearance of History. Different temporary schemes support this transit; among them, a pass from Synchrony to Diachrony, a (...) change from iteration to the Event, the circularity to the linearity. In it follows we propose to observe some implications and forms of articulation of an Historical Time and Social Acceleration in the sense that both of them are connecting and mutual depending elements.

El artículo busca analizar dentro de la obra El extraño caso del Dr. Jekyll y Mr. Hyde (2015) de Robert Louis Stevenson (1850-1894), el fenómeno del doppelgänger. Este fenómeno tomó gran predominancia en la literatura del siglo XIX como recurso literario que siguió estando presente en obras posteriores. Por lo que consideramos pertinente iniciar un diálogo ético sobre esta temática, repasando este relato que dio a conocer el fenómeno del doppelgänger al público lector. Así, describiremos primeramente qué es este último, (...) para luego hacerle un rastreo dentro de la obra de Stevenson, destacando sus elementos más relevantes. Finalmente se busca profundizar esta temática del doble relacionándolo con un debate ético que de allí se pueda formar, proponiendo esta misma obra literaria como medio que nos incita y mueve a replantearnos nuestro ser ético en sociedad y considerando aquellos elementos más detestables en nuestra humanidad, contenidos en el doppelgänger. Por último, extendemos este análisis utilizando los Pensamientos (1918) de Blaise Pascal, que nos pueden ayudar a adentrarnos en un área existencial sobre la condición humana y la moralidad.

The philosophy of perception has been mostly focused on vision, to the detriment of other modalities like audition or olfaction. In this paper I focus on olfaction and olfactory experience, and raise the following questions: is olfaction a perceptual-representational modality? If so, what does it represent? My goal in the paper is, firstly, to provide an affirmative answer to the first question, and secondly, to argue that olfaction represents odors in the form of olfactory objects, to which olfactory qualities are (...) attributed. In order to do this I develop an empirically adequate notion of olfactory object that is sensitive to the peculiarities of olfaction, and defend it against various objections. (shrink)

Resenha do artigo "Morality as a System of Hypothetical Imperatives", de Philippa Foot.

A tese principal deste artigo é que se nos perguntarmos pela referência do conceito “alienação”, nos encontraremos na posição de ter que admitir que ela é ambígua. Faço uso do termo ambiguidade referencial para apontar duas fontes de ambiguidade: (i) pode se referir ao trabalho como objeto ou sujeito da alienação; (ii) pode designar ou não uma referência. Argumento a literatura marxista de apoio não explicitou essa ambiguidade, pois está presa no paradigma de uma “leitura genitivo-subjetiva”. Não se trata, porém, (...) de defender uma “leitura genitivo-objetiva”, mas mostrar que a sua plausibilidade ajuda a esclarecer que os textos do “jovem Marx” eram ambíguos. Para isso, procuro mostrar o que uma “leitura genitivo-objetiva” diria sobre três contextos específicos de uso de “alienação” e “estranhamento”: Manuscritos de 1844 (parte 1), A Sagrada Família e A Ideologia Alemã (parte 2). Busco também explicitar como essa leitura só faz sentido sob a pressuposição de um nominalismo semântico. (shrink)
