Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory for groups (...) (n = 74). Assessments were performed at pre-, post-, and 6-month follow-up phases. Results. Meditation awareness training participants demonstrated significant and sustained improvements over control group participants in FMS symptomatology, pain perception, sleep quality, psychological distress, non-attachment (to self, symptoms, and environment), and civic engagement. A mediation analysis found that (1) civic engagement partially mediated treatment effects for all outcome variables, (2) non-attachment partially mediated treatment effects for psychological distress and sleep quality, and (3) non-attachment almost fully mediated treatment effects for FMS symptomatology and pain perception. Average daily time spent in meditation was found to be a significant predictor of changes in all outcome variables. Conclusions. Meditation awareness training may be a suitable treatment for adults with FMS and appears to ameliorate FMS symptomatology and pain perception by reducing attachment to self. (shrink)

This three-part paper presents Gordon Pask’s conversation theory (CT) and interaction of actors theory (IA) and outlines ways to apply these cybernetic approaches to designing technologies and scenarios for both formal and informal learning. The first part of the paper covers concepts central to CT and IA, explaining the relationship between conceptual and mechanical operators, and machines mediating informal and formal learning. The second part of the paper applies visual representations of CT and IA to understanding the use of (...) Pask’s course assembly systems (CASTE and THOUGHTSTICKER), created between the late 1960s and the 1980s, and the ThoughtShuffler search interface, created in the 2010s. The third part proposes two pathways for design based on CT and IA: firstly, the potential for designers and observers to reformulate the qualities of tools and learning scenarios to augment human thinking and collective action; and secondly, the possibility to create tools with malleable interfaces that allow users to become intermediaries rather than consumers of knowledge.

Aquinas’s process of abstraction of the particular thing into a universal concept is of pivotal importance for grounding his philosophy and theology in a natural framework. Much has been said and written regarding Aquinas’s doctrine of abstraction, yet recent studies still consider it to be ‘nothing more than a kind of magic.’ This problematic claim is not without foundation, for in trying to understand exactly how this process works, we are constantly faced with an unbridgeable abyss and the repeated vague (...) explanations made by Aquinas. The plain truth is that Aquinas explains what abstraction ought to do and yet, most of the time, he does not explain how it is to be done. This paper intends to show that although Aquinas does not present us with a mechanism for the theory of abstraction, we are nevertheless able to construct a viable mechanism which accords with Aquinas’s guidelines. The aim of constructing a working mechanism that corresponds to what Aquinas demands of the process of abstraction is twofold: First, it attempts to extricate Aquinas’s doctrine of abstraction from the claims of being a quasi-natural doctrine. Second, a viable process of abstraction which is derived from Aquinian-Aristotelian sources can approach contemporary cognitive problems from a fresh point of view. (shrink)

Martin Heidegger devotes extensive discussion to medieval philosophers, particularly to their treatment of Truth and Being. On both these topics, Heidegger accuses them of forgetting the question of Being and of being responsible for subjugating truth to the modern crusade for certainty: ‘truth is denied its own mode of being’ and is subordinated ‘to an intellect that judges correctly’. Though there are some studies that discuss Heidegger’s debt to and criticism of medieval thought, particularly that of Thomas Aquinas, there (...) is no constructive reply to his assertions. As a result, Heidegger’s critique had an unprecedented effect on the credibility of medieval philosophy, whereby great portions of the philosophical community dismiss it altogether as an illegitimate Onto‐Theology. It is the aim of this study to offer a constructive reply that will fundamentally grapple with these allegations. By constructive reply we mean not only a reply that avoids the problems Heidegger raises regarding existence, essence and truth, but more importantly, one that uses Heidegger’s criticism in order to present a more insightful account of these notions. The present study is composed of two parts where the second serves as a sort of addendum. The first part, the core of this study, is an attempt to develop an understanding of the distinction between essence and existence that, on the one hand, accords with Heidegger’s criticism while on the other hand advances our understanding of how we think and understand reality. After presenting Heidegger’s depiction of Aquinas’s distinction between essence and existence (esse) as a real distinction, the study will present several views propounded by scholars of Aquinas regarding the status of this distinction. It will be argued that it is not clear whether the distinction is real, formal or conceptual, and that different types of distinction are applied in different places, particularly in regard to the phantasm that Aquinas considers essential to the human act of thinking. The second part diverges from the first part and focuses on Heidegger’s criticism of Aquinas’s conception of truth as adequation, i.e., what it is that grounds the possibility of truth as adequation. This divergence is necessary in order to present a full metaphysical response to Heidegger’s criticism. Since the aim of the present study is to argue that Aquinas’s philosophical system can contend with Heidegger’s criticism, a partial reply would greatly diminish its effectiveness. (shrink)

The emergence of Large Language Models (LLMs) and advancements in Artificial Intelligence (AI) offer an opportunity for computational social science research at scale. Building upon prior explorations of LLM agent design, our work introduces a simulated agent society where complex social relationships dynamically form and evolve over time. Agents are imbued with psychological drives and placed in a sandbox survival environment. We conduct an evaluation of the agent society through the lens of Thomas Hobbes's seminal Social Contract Theory (SCT). (...) We analyze whether, as the theory postulates, agents seek to escape a brutish "state of nature" by surrendering rights to an absolute sovereign in exchange for order and security. Our experiments unveil an alignment: Initially, agents engage in unrestrained conflict, mirroring Hobbes's depiction of the state of nature. However, as the simulation progresses, social contracts emerge, leading to the authorization of an absolute sovereign and the establishment of a peaceful commonwealth founded on mutual cooperation. This congruence between our LLM agent society's evolutionary trajectory and Hobbes's theoretical account indicates LLMs' capability to model intricate social dynamics and potentially replicate forces that shape human societies. By enabling such insights into group behavior and emergent societal phenomena, LLM-driven multi-agent simulations, while unable to simulate all the nuances of human behavior, may hold potential for advancing our understanding of social structures, group dynamics, and complex human systems.

Following an Open conception of Divine Foreknowledge, that holds that man is endowed with genuine freedom and so the future is not definitely determined, it will be claimed that human freedom does not limit the divine power, but rather enhances it and presents us with a barrier against arbitrary use of that power. This reading will be implemented to reconcile a well-known quarrel between two important interpreters of Duns Scotus, Allan B. Wolter and Thomas Williams, each of whom supports (...) a different interpretation of the way God acts according to right reason. (shrink)

The purpose of the following text is to give readers a general introduction to Gordon Pask’s conversation theory, which is considered here to be a cybernetic and epistemological account of concept-forming and concept-sharing through conversational discourse and practice. While Pask devoted three lengthy tomes to articulate the theory and its applications, I believe it is necessary to give readers who are interested in conversation theory a general introduction to what I believe are the key features of his work in (...) this area. I argue that conversation theory should be considered an inferential account of the theory of concepts rather than a representational account, by virtue of Pask’s argument that a concept must be a process that involves many other concepts.

The problem of divine impassibility, i.e., of whether the divine nature in Christ could suffer, stands at the center of a debate regarding the nature of God and his relation to us. Whereas philosophical reasoning regarding the divine nature maintains that the divine is immutable and perfect in every respect, theological needs generated an ever-growing demand for a passionate God truly able to participate in the suffering of his creatures. Correlating with the different approaches of Thomas Aquinas and John (...) Duns Scotus, the paper develops an incarnation model that aims, on the one hand, to solve the dualistic problem between the divine and human natures, and on the other hand to make room for both impassible and passible elements in God, and so to make room within the patristic impassible model for genuine suffering in God. The discussion, though centered around Christ's im/passibility and passions, can easily be modified to approach the body-mind problem since the essence of the problems is the same. (shrink)

The paper will explore a key tension between eternity and temporality that comes to the fore in the seeming contradiction between freedom of the human will and divine foreknowledge of future contingents. It will be claimed that Duns Scotus’s adaptation of Thomas Aquinas’s view reduces the tension between a human being’s freedom and divine foreknowledge of future contingents to the question of how to conflate the now of eternity and our experience of the instantaneous now. Scotus’s account of the (...) matter is unfortunately not satisfying and it is the purpose of this paper to develop this insight further in a speculative manner. In order to make such co-nowness possible, it will be asked how the eternal and the temporal can co-cause together. This problem will be tackled through a development of Scotus’s doctrine of the will taken elsewhere, in order to examine how the divine and the human wills can occur together. It will be claimed that such co-willing produces a co-nowness of the eternal and the instantaneous ‘nows’ which generates a logical temporal movement. (shrink)

Bernard McGinn was a great historian of Christianity. But in this book under review he fails to do justice to the history of the Summa. He fails to understand the ontologies of the economic theories of Bernard Lonergan and the theology of Karl Rahner, for examples. The book is patchy and seems under-researched. McGinn does not do justice to the influence of the Summa as a text which forms a bridge between St. Augustine of Hippo and Hannah Arendt and Jean (...) Lyotard. The review is marred by a typos which the proofreader(s) of Prabuddha Bharata overlooked. Of course, the onus of the error lies with the reviewer. (shrink)

RELAÇÃO E EFEITOS BIOQUÍMICO-NUTRICIONAIS SOBRE OS TRANSTORNOS DO CICLO ESTRAL DE VACAS -/- Emanuel Isaque Cordeiro da Silva Departamento de Agropecuária – IFPE Campus Belo Jardim [email protected] ou [email protected] WhatsApp: (82)98143-8399 -/- •__6. Transtornos do ciclo estral -/- Qualquer alteração na frequência, duração ou intensidade do ciclo estral é considerada uma perturbação do ciclo, cujas origens variam etiologicamente. As perturbações do ciclo podem originar-se em qualquer das partes do eixo hipotálamo-hipófise-ovário (FRAZER, 2005; GORDON, 1996). Pode ou não ser do (...) tipo permanente e pode depender de sua origem, momento e intensidade cursar com outras alterações reprodutivas, por exemplo uma retenção do corpo lúteo, dá lugar a prolongamento da fase lútea, altos níveis de progesterona circulante e pode, finalmente, desencadear em um cisto luteal ou em uma metrite. Entre os fatores desencadeadores da falha do ciclo estral estão os fatores de origem nutricional, dentre eles: 6.1 Minerais 6.1.1 Relação Na:K (Sódio: Potássio) A deficiência de sódio pode causar distúrbios do ciclo estral, isto porque as células animais intracelularmente possuem uma alta concentração de K e uma baixa concentração de Na, esta relação pode chegar a 10:1 ou mais, em relação ao meio externo. Com esta relação, as concentrações intracelulares estão em equilíbrio com o meio externo. A absorção e secreção de cátions pela célula para conseguir o equilíbrio é simultânea, gerada por um sistema de transporte específico chamado "bomba Na-K". Se a nível celular não existe um balanço iônico de K:Na, a maior prioridade das células tubulares do rim é a de conseguir novamente um equilíbrio, o mecanismo destas células é o da reabsorção do íon que se encontre em excesso de água, diminuindo a quantidade deste no líquido para manter as funções em equilíbrio dinâmico. Os desequilíbrios não compensados a nível celular ou renal, levam a alterações na condutividade nervosa por alteração da bomba de transmissão elétrica. O ciclo estral é alterado por diminuir a expressividade dos sinais comportamentais de estro, que são produzidos por concentrações crescentes de estrogênio mas com alta necessidade de adequação nervosa para a exposição corporal do cio e a aceitação da monta. O potássio, em particular, desempenha um papel fundamental como coator em certas interações enzimáticas, incluindo a transferência de energia, a síntese de proteínas e o metabolismo de hidratos de carbono, em especial nos sistemas em que o ADP está envolvido, as hexoquinases e a anidrase carbônica. O sódio, por sua vez, é o principal cátion extracelular, regula o equilíbrio hídrico no organismo e a mecânica de fluidos, desta forma regula a pressão osmótica e a troca aquosa nos tecidos. Devido a esta função, um dos fatores importantes do fluxo Na:K é o rim, que é controlado pela aldosterona, a principal hormona reguladora da absorção de sódio e excreção de potássio. Qualquer desequilíbrio na relação Na:K, afetará o ciclo estral, de maneira direta e indireta, através da alteração na síntese de proteínas e da perda da regulação hídrica, fator importante pelas secreções que devem acompanhar as manifestações de cio/estro. 6.1.2 Relação Cobalto (Co) A deficiência de cobalto gera um efeito biológico determinado pela sua presença na molécula da vitamina B12, a qual regula a hematopoese (Ativa a síntese de protoporfirina) e afeta o metabolismo do nitrogênio e dos carboidratos. A vitamina B12 atua como uma coenzima da transmetilação (síntese do glutamato mutase, metilmalonil-CoA-Mutase, diol-dehidratase e redução dos ribonucleótidos a desoxirribonucleótidos, isomerização da a-lisina, etc.). Especialmente em ruminantes, a reação mutase da metilmalonina-CoA está relacionada com o metabolismo do ácido propiônico e, portanto, com a síntese de glicose e o equilíbrio energético. O cobalto também está envolvido na carboxilação da propionil-CoA à metilmalonil-CoA e na isomerização deste último para succinil-CoA. O metabolismo do ácido propiônico ocorre no fígado e é reduzido pelo fato do metilmalonil não poder ser convertido em succinil-CoA, impedindo a sua passagem para oxalacetato e glicose, gerando uma relação inversa entre os níveis de energia e proteína; causando uma diminuição de GnRH que afeta negativamente a liberação de LH que, por sua vez, cria um aumento na FSH. Isso produz uma anulação da ovulação e, consequentemente, ausência de um ciclo estral verdadeiro. Vale reforçar que, para prevenção da deficiência do cobalto, o criador pode optar pelo fornecimento de volumosos que dispõem de quantidades de cobalto que suprem as exigências dos animais, ou pela inserção de sais de cobalto à mistura da ração, sempre no intervalo sugerido de 0,07 e 0,11 mg/kg para cada animal, suprindo a necessidade do mesmo e garantindo assim a prevenção dos transtornos do ciclo estral ou outras afecções do sistema reprodutivo. 6.1.3 Relação Cobre (Cu) e Molibdênio (Mo) A deficiência de cobre gera, indiretamente, molibdênio, durante esse processo, tanto o macho como a fêmea são inférteis ou sub-férteis, mas, em geral, os transtornos surgem não por molibdeniose mas por hipocuprose condicionada por excesso de molibdênio nas pastagens e pelos sulfatos presentes na água de bebida (BREM, 2016). Isso leva à formação de tiomolibdato no rúmen, que por sua vez combina com o cobre para formar tiomolibdato de cobre, sal muito insolúvel. O tiomolibdato presente, formado em excesso e que não encontra cobre suficiente, contribuirá para produzir a diarreia, limitando ainda mais a absorção de cobre. A interferência mais importante do molibdênio ocorre no processo metabólico do cobre, interferindo sua atividade enzimática. O molibdênio atua sobre o complexo sulfeto-oxidase hepático. A enzima que está envolvida na oxidação de metabolitos sulfurados, reduz a sua atividade na presença de altos teores de molibdênio, especialmente quando a quantidade de cobre é baixa. Daqui resulta a formação de sulfureto de cobre, muito insolúvel e, portanto, pouco ou nada utilizável pelas células e/ou tecidos (QUIROZ-ROCHA & BOUDA, 2001). O excesso de molibdênio nas pastagens ou na água de bebida reduz a quantidade de cobre no fígado, mas para uma dada dose de molibdênio, esta redução é diretamente proporcional ao aumento dos sulfatos na ingestão, porque só na presença de sulfatos o molibdênio exerce sua ação limitante. O melhor modo de tratar o molibdênio e a ação dos sulfatos sobre o cobre, é aumentar a quantidade de cobre disponível pelos animais, seja por via bucal ou parenteral. Desta forma, há aumentos na cupremia e no ganho de peso. É conveniente, para o efeito, efetuar um controle dos resultados mediante a observação clínica, pesagem dos animais e análise de cobre no sangue. Isso permitirá estabelecer as doses ideais e adequadas para cada estabelecimento e efetuar um estudo econômico da suplementação (BAVERA, 2002). Como já foi tratado o requerimento do cobre para evitar os problemas reprodutivos das vacas, falemos do molibdênio (Mo). O Mo é um elemento primordial para bovinos leiteiros, uma vez que é componente de uma enzima presente no leite (xantina oxidasse). A deficiência de Mo a nível prático não foi relatada, porém casos podem acontecer. Para ovinos, que é uma espécie ruminante, a concentração exigida pelo animal em Mo presente na MS é de 5 a 10 mg/kg, porém deve levar em consideração a relação crítica entre o Mo e o Cu que deve ser no máximo 20 e nunca superior. O nível crítico de toxidade de Mo nos alimentos volumosos (forrageiras, gramíneas e leguminosas) não pode ultrapassar os 6% por kg de MS. Através de todos esses cuidados, o criador poderá obter sucesso tanto na prevenção contra os distúrbios do ciclo estral das vacas, quanto de outras complicações como toxidade, desnutrição, etc. 6.2 Relação energia:proteína Em relação ao aumento do consumo de proteína crua ou de deficiência de energia, aumenta-se a quantidade de ureia no sangue e produz-se uma toxicidade tecidular, afetando o endométrio e diminuindo a produção de prostaglandinas, que são as encarregadas de manter o corpo lúteo, caso não se mantenha acaba provocando um ciclo estral longo. A situação pode ser explicada a nível do eixo hipotálamo-hipófise, no qual os baixos níveis de glicose inibem a secreção de GnRH e resultam na diminuição da pulsatilidade da LH, seja por ação direta ou mediada através das ß-endorfinas. Outro fator que afeta o crescimento folicular é a nutrição, especificamente a perda da condição corporal, quando o animal não se alimenta direito ou quando se alimenta não tem uma condição balanceada que supra suas exigências nutricionais e que tenha um aceitável ganho de peso diário (GPD), acaba perdendo massa muscular ou de gordura, em outras palavras altera-se a condição corporal do mesmo, e se a perda for de 22 a 24 % de peso corporal (PC), os animais que perdem essa condição entram em anestro o que acaba tornando um animal inviável para a reprodução e também para o abate, uma vez que encontra-se fora do peso ideal. Tanto as proteínas quanto a energia foram tratados em trabalhos anteriores, porém nunca é tarde para salientar que ambas devem ser fornecidas em qualidade e quantidade que consiga favorecer ao desenvolvimento do animal e aos mecanismos fisiológicos do mesmo. 6.3 Fito-toxidade Finalmente, um fator adicional que induz a alteração da ciclicidade estral são os fitoestrógenos, plantas com altos teores de isoflavonas que possuem, no organismo animal, uma ação estrogênica. Os fitoestrógenos estão amplamente difundidos, nos trevos, alfafa, milho e nas pastagens de cultivo intensivo. Os fitoestrogênios são diferentes dos estrogênios produzidos pelo animal, mas a sua ação é idêntica nos receptores do trato reprodutivo; o seu metabolismo e excreção é diferente (por exemplo, desmetilização) e a sua excreção renal através dos glicoronosidos, assim mesmo a formação de ésteres sulfatos no tecido hepático é menor, acumulando-se em circulação e alterando a duração da fase estrogênica do ciclo, isso leva à ninfomania das vacas e com ela a perda da função reprodutiva. Deve-se estar atento ao pasto que se cultiva e ao solo em que se implanta o pasto, uma vez que o solo pode ter excessos de minerais prejudiciais ao animal e que o coloque em uma situação de toxidade, já que a planta absorve do solo o excesso e da planta vai para o animal por meio direto ou pela silagem. Um exemplo é o teor de molibdênio na planta que não pode ser maior que 6%, se for ocorrerá inúmeras transformações fisiológicas maléficas ao animal, que acabará sendo descartado do objetivo que seria a reprodução na fazenda. -/- Apoio -/- Realização -/- REFERÊNCIAS BIBLIOGRÁFICAS BAVERA, Guillermo Alejandro.

Reproductive genetic technologies allow parents to decide whether their future children will have or lack certain genetic predispositions. A popular model that has been proposed for regulating access to RGTs is the ‘genetic supermarket’. In the genetic supermarket, parents are free to make decisions about which genes to select for their children with little state interference. One possible consequence of the genetic supermarket is that collective action problems will arise: if rational individuals use the genetic supermarket in isolation from one (...) another, this may have a negative effect on society as a whole, including future generations. In this article we argue that RGTs targeting height, innate immunity, and certain cognitive traits could lead to collective action problems. We then discuss whether this risk could in principle justify state intervention in the genetic supermarket. We argue that there is a plausible prima facie case for the view that such state intervention would be justified and respond to a number of arguments that might be adduced against that view.

How should we make distributive decisions when there is not enough of the good to go around, or at least not enough of it right now? What does fairness require in such cases? In what follows, we distinguish between cases of scarcity and bottleneck cases, and we argue that both arguments for lotteries and arguments for queues have merit, albeit for different distributive scenarios. When dealing with scarcity not everyone can get the good. A secondary good that can be distributed (...) fairly is the chances of obtaining the good. In cases of scarcity, lotteries are the best way of allocating chances of obtaining the good fairly. When dealing with bottlenecks, the secondary good that can and ought to be distributed fairly is waiting time. Queues are best suited to distribute the good of waiting time fairly. (shrink)

I discuss here the definition of computer simulations, and more specifically the views of Humphreys, who considers that an object is simulated when a computer provides a solution to a computational model, which in turn represents the object of interest. I argue that Humphreys's concepts are not able to analyse fully successfully a case of contemporary simulation in physics, which is more complex than the examples considered so far in the philosophical literature. I therefore modify Humphreys's definition of simulation. I (...) allow for several successive layers of computational models, and I discuss the relations that exist between these models, the computer, and the object under study. An aim of my proposal is to clarify the distinction between computational models and numerical methods, and to better understand the representational and the computational functions of models in simulations.

There is a very plausible principle linking abilities and possibilities: If S is able to Φ, then it is metaphysically possible that S Φ’s. Jack Spencer recently proposed a class of counterexamples to this principle involving the ability to know certain propositions. I renew an argument against these counterexamples based on the unknowability of Fitch propositions. In doing so, I provide a new argument for the unknowability of Fitch propositions and show that Spencer’s counterexamples are in tension with a principle (...) weaker than the one linking abilities and possibilities.

The paper by Monteiro, Musten and Compson (2014) is to be commended for providing a comprehensive discussion of the compatibility issues arising from the integration of mindfulness – a 2,500-year-old Buddhist practice – into research and applied psychological domains. Consistent with the observations of various others (e.g., Dunne, 2011; Kang & Whittingham, 2010), Monteiro and colleagues have not only highlighted that there are differences in how Buddhism and contemporary mindfulness interventional approaches interpret and contextualize mindfulness, but there are also differing (...) interpretations of mindfulness within Buddhism. These apparent differences within Buddhism are arguably more noticeable when making comparisons across Buddhist vehicles (i.e., Theravada, Mahayana, Vajrayana), but to a lesser extent intra-vehicular differences can also be said to exist (i.e., differences between Buddhist traditions of the same vehicle). This commentary investigates the validity of some of these different Buddhist constructions of mindfulness, and then discusses how a better understanding of their scriptural and conceptual soundness (or lack thereof) may help to reconcile some of the actual and perceived incompatibility between Buddhist practice and contemporary secular mindfulness-based approaches.

I argue that classical theism is in tension with a kind of modal recombination principle known as ‘cut-and-paste’. I develop this tension at length, giving two arguments against theism based on cut-and-paste. I then both lay out and respond to various original proposals for reconciling theism with cut-and-paste. I conclude by measuring the cost of having to deny cut-and-paste. I argue that while there is an intuitive cost to this consequence of theism, theists also have plausible ways of addressing various (...) motivations for cut-and-paste. (shrink)

In this paper we show how a realistic normative democratic theory can work within the constraints set by the most pessimistic empirical results about voting behaviour and elite capture of the policy process. After setting out the empirical evidence and discussing some extant responses by political theorists, we argue that the evidence produces a two-pronged challenge for democracy: an epistemic challenge concerning the quality and focus of decision-making and an oligarchic challenge concerning power concentration. To address the challenges we then (...) put forward three main normative claims, each of which is compatible with the evidence. We start with a critique of the epistocratic position commonly thought to be supported by the evidence. We then introduce a qualified critique of referenda and other forms of plebiscite, and an outline of a tribune-based system of popular control over oligarchic influence on the policy process. Our discussion points towards a renewal of democracy in a plebeian but not plebiscitarian direction: Attention to the relative power of social classes matters more than formal dispersal of power through voting. We close with some methodological reflections about the compatibility between our normative claims and the realist program in political philosophy. (shrink)

The twin goals of this essay are: to investigate a family of cases in which the goal of guaranteed convergence to the truth is beyond our reach; and to argue that each of three strands prominent in contemporary epistemological thought has undesirable consequences when confronted with the existence of such problems. Approaches that follow Reichenbach in taking guaranteed convergence to the truth to be the characteristic virtue of good methods face a vicious closure problem. Approaches on which there is a (...) unique rational doxastic response to any given body of evidence can avoid incoherence only by rendering epistemology a curiously limited enterprise. Bayesian approaches rule out humility about one’s prospects of success in certain situations in which failure is typical. (shrink)

Voting Advice Applications (VAAs) are interactive online tools designed to assist voters by improving the basis on which they decide how to vote. In recent years, they have been widely adopted, but their design is the subject of ongoing and often heated criticism. Most of these debates focus on whether VAAs accurately measure the standpoints of political parties and the preferences of users and on whether they report valid results while avoiding political bias. It is generally assumed that if their (...) methodology is sound, then VAAs can be seen as strengthening the democratic process. But as we argue in this chapter, the setup of VAAs raises basic questions of normative democratic theory as well. Insofar as VAAs are supposed to improve the functioning of the democratic process, it must be clarified in what sense they aim to make a contribution, before it even makes sense to discuss their effectiveness at doing so. -/- VAAs are often intended to enhance the democratic process by one or all of the following: (I) informing voters about the policy standpoints of political parties (or individual candidates), (2) increasing voter turnout, and (3) ensuring that the composition of parliaments more accurately reflects the political attitudes of the electorate. In the next three sections, we discuss three central bones of contention in current democratic theory that are crucial to these ways in which VAAs typically take themselves to contribute to strengthening the democratic process: -/- 1. Questions about citizen competence: What forms of competence do citizens need to have, and to what extent, for a democracy to function properly? -/- 2. Questions about political participation: What forms and extent of participation are vital to democracy? -/- 3. Questions about democratic representation: How should the relation between the elected and the electorate be understood? -/- For each issue we aim to show, first, how the design and setup of mainstream VAAs are tacitly structured by a specific conception of the democratic aim at issue and, second, what some alternative positions on these questions are within contemporary political theory. In the final section, we will discuss some of the implications of this analysis for the responsibilities of VAA developers, and particularly for the procedural neutrality to which they are typically committed. Our conclusion will be that once these issues are identified, developers of VAAs should either argue in favour of their views on democratic competence, participation and representation, or they should rethink the design of VA As in ways that move beyond their current assumptions, or both.

In general, Confucians have taken a dim view of the law. They have felt warranted in this view by a reading of Confucius’ Analects 2.3 in which the Master apparently disparages law-centered governance. Two great Confucian philosophers, however, Zhu Xi and Jeong Yakyong (widely known by his pen name, Dasan), view the role of law in society differently. Like all Confucians, they teach the cultivation of virtue, but alongside building social harmony through ritual and good character, these two philosophers perceive (...) that social order also requires the penal law. In this paper, I argue that Zhu Xi and Dasan, and Dasan in particular, follow the evidentiary lead of the classical Chinese philosopher Mozi to support their legal philosophy. Mozi offered three standards for establishing truth claims: empirical evidence from common life, authoritative evidence, and evidence of outcomes. Mozi’s empirical standard takes evidence of common life from what ordinary people have seen. Zhu Xi and Dasan take the evidence of common life, not from what the people have seen, but from common understandings contained in the written language. They use this approach to arrive at a different understanding of Analects 2.3 than other Confucians, one that relates the content of that passage to Analects 12.17. They interpret the passage on a philological basis that supports the presence of penal law from a perspective of ordinary life. For authoritative evidence, Zhu Xi and Dasan like Mozi appeal to the authority of the ancient sages, who register their support for penal law. Dasan also follows Mozi’s evidentiary lead in the evidence of outcomes by fully developing a consequential picture of how the absence of law detrimentally affects society. On this point, Dasan establishes a new and revolutionary legal outlook that differs from that of Zhu Xi. I show Dasan taking lessons from the classical Legalists to arrive at this position warranted by the evidence of outcomes. Having satisfied the three evidentiary standards, Dasan thus establishes the importance of the penal law from a Confucian perspective. (shrink)

While Aquinas’s primary notion of truth as adequation is applied to God and man in somewhat different ways, it is apparent that it is not applicable to the angels, at least not in the same way. However, since truth is a transcendental, and as transcendentals are convertible, one may claim that the transcendental systems that apply to various beings differ. In order to consolidate the universality of the transcendental system, the study aims to show the manner truth as adequation can (...) be applied to the angels. (shrink)

In Philosophy and Technology 36, David Watson discusses the epistemological and metaphysical implications of unsupervised machine learning (ML) algorithms. Watson is sympathetic to the epistemological comparison of unsupervised clustering, abstraction and generative algorithms to human cognition and sceptical about ML’s mechanisms having ontological implications. His epistemological commitments are that we learn to identify “natural kinds through clustering algorithms”, “essential properties via abstraction algorithms”, and “unrealized possibilities via generative models” “or something very much like them.” The same issue contains a commentary (...) on Watson’s paper in which Tom Sterkenburg fiercely opposes the epistemological claim that clustering algorithms can identify natural kinds. Sterkenburg argues there’s nothing about clustering arguments themselves that enables natural kind identification. What’s at stake in the Watson-Sterkenburg debate is whether it is possible for clustering algorithms to identify natural kinds and whether they underly human identification of natural kinds. My contribution to the Watson-Sterkenburg debate is twofold. First, I argue Sterkenburg’s criticism of Watson’s claim is too severe because it denies any clustering algorithm to identify any natural kind. Secondly, I argue Watson’s reply overestimates both clustering algorithms’ and humans’ access to natural kinds and his claim has to be restricted accordingly to ‘We identify kinds via clustering algorithms, or something very much like them’.

I examine two related arguments for the claim that if God is omnipotent, God cannot lack abilities such as the ability to do evil or to act irrationally. Both arguments concern the idea that omnipotence is inconsistent with being dominated with respect to abilities. I raise new issues in the formulation of such dominance principles about ability, and attempt to solve them. I also discuss and reject existing objections to these arguments. I conclude that these arguments are promising but not (...) conclusive, and that important work remains to be done in formulating the relevant dominance principles. (shrink)

Schervish (1985b) showed that every forecasting system is noncalibrated for uncountably many data sequences that it might see. This result is strengthened here: from a topological point of view, failure of calibration is typical and calibration rare. Meanwhile, Bayesian forecasters are certain that they are calibrated---this invites worries about the connection between Bayesianism and rationality.

Bayesians often assume, suppose, or conjecture that for any reasonable explication of the notion of simplicity a prior can be designed that will enforce a preference for hypotheses simpler in just that sense. But it is shown here that there are simplicity-driven approaches to curve-fitting problems that cannot be captured within the orthodox Bayesian framework.

This paper is concerned with the relation between two notions: that of two solutions or models of a theory being related by a symmetry of the theory and that of solutions or models being physically equivalent. A number of authors have recently discussed this relation, some taking an optimistic view, on which there is a suitable concept of the symmetry of a theory relative to which these two notions coincide, others taking a pessimistic view, on which there is no such (...) concept. The present paper arrives at a cautiously pessimistic conclusion. (shrink)

It is widely thought that chance should be understood in reductionist terms: claims about chance should be understood as claims that certain patterns of events are instantiated. There are many possible reductionist theories of chance, differing as to which possible pattern of events they take to be chance-making. It is also widely taken to be a norm of rationality that credence should defer to chance: special cases aside, rationality requires that one’s credence function, when conditionalized on the chance-making facts, should (...) coincide with the objective chance function. It is a shortcoming of a theory of chance if it implies that this norm of rationality is unsatisfiable. The primary goal of this paper is to show, on the basis of considerations concerning computability and inductive learning, that this shortcoming is more common than one would have hoped. (shrink)

Under so-called primitive ontology approaches, in fully describing the history of a quantum system, one thereby attributes interesting properties to regions of spacetime. Primitive ontology approaches, which include some varieties of Bohmian mechanics and spontaneous collapse theories, are interesting in part because they hold out the hope that it should not be too difficult to make a connection between models of quantum mechanics and descriptions of histories of ordinary macroscopic bodies. But such approaches are dualistic, positing a quantum state as (...) well as ordinary material degrees of freedom. This paper lays out and compares some options that primitive ontologists have for making sense of the quantum state. (shrink)

1.Summary The key terms. 1. Key term: ‘Sunyata’. Nagarjuna (Kumarajiva) is known in the history of Buddhism mainly by his keyword ‘sunyata’. This word is translated into English by the word ‘emptiness’. The translation and the traditional interpretations create the impression that Nagarjuna (Kumarajiva) declares the objects as empty or illusionary or not real or not existing. What is the assertion and concrete statement made by this interpretation? That nothing can be found, that there is nothing, that nothing exists? Was (...) Nagarjuna (Kumarajiva) denying the external world? Did he wish to refute that which evidently is? Did he want to call into question the world in which we live? Did he wish to deny the presence of things that somehow arise? My first point is the refutation of this traditional translation and interpretation. 2. Key terms: ‘Dependence’ or ‘relational view’. My second point consists in a transcription of the keyword of ‘sunyata’ by the word ‘dependence’. This is something that Nagarjuna (Kumarajiva) himself has done. Now Nagarjuna’s (Kumarajiva’s) central view can be named ‘dependence of things’. Nagarjuna (Kumarajiva) is not looking for a material or immaterial object which can be declared as a fundamental reality of this world. His fundamental reality is not an object. It is a relation between objects. This is a relational view of reality. This is the heart of Nagarjuna’s (Kumarajiva’s) ideas. In the 19th century a more or less unknown Italian philosopher, Vincenzo Goberti, spoke about relations as the mean and as bonds between things. Later, in quantum physics and in the philosophy of Alfred North Whitehead we are talking about interactions and entanglements. These ideas of relatedness or connections or entanglements in Eastern and Western modes of thought are the main idea of this essay. Not all entanglements are known. Just two examples: the nature of quantum entanglements is not known. Quantum entanglements should be faster than light. That's why Albert Einstein had some doubts. A second example: the completely unknown connections between the mind and the brain. Other examples are mysterious like the connections between birds in a flock. Some are a little known like gravitational forces. 3. Key terms: ‘Arm in arm’. But Nagarjuna (Kumarajiva) did not stop there. He was not content to repeat this discovery of relational reality. He went on one step further indicating that what is happening between two things. He gave indications to the space between two things. He realized that not the behaviour of bodies, but the behaviour of something between them may be essential for understanding the reality. This open space is not at all empty. It is full of energy. The open space is the middle between things. Things are going arm in arm. The middle might be considered as a force that bounds men to the world and it might be seen as well as a force of liberation. It might be seen as a bondage to the infinite space. 4. Key term: Philosophy. Nagarjuna (Kumarajiva), we are told, was a Buddhist philosopher. This statement is not wrong when we take the notion ‘philosophy’ in a deep sense as a love to wisdom, not as wisdom itself. Philosophy is a way to wisdom. Where this way has an end wisdom begins and philosophy is no more necessary. A.N. Whitehead gives philosophy the commission of descriptive generalization. We do not need necessarily a philosophical building of universal dimensions. Some steps of descriptive generalization might be enough in order to see and understand reality. There is another criterion of Nagarjuna’s (Kumarajiva’s) philosophy. Not his keywords ‘sunyata’ and ‘pratityasamutpada’ but his 25 philosophical examples are the heart of his philosophy. His examples are images. They do not speak to rational and conceptual understanding. They speak to our eyes. Images, metaphors, allegories or symbolic examples have a freshness which rational ideas do not possess. Buddhist dharma and philosophy is a philosophy of allegories. This kind of philosophy is not completely new and unknown to European philosophy. Since Plato’s allegory of the cave it is already a little known. (Plato 424 – 348 Befor Current Era) The German philosopher Hans Blumenberg has underlined the importance of metaphors in European philosophy. 5. Key terms: Quantum Physics. Why quantum physics? European modes of thought had no idea of the space between two this. They were bound to the ideas of substance or subject, two main metaphysical traditions of European philosophical history, two main principles. These substances and these subjects are two immaterial bodies which were considered by traditional European metaphysics as lying, as a sort of core, inside the objects or underlying the empirical reality of our world. The first European scientist who saw with his inner eye the forces between two things had been Michael Faraday (1791-1867). Faraday was an English scientist who contributed to the fields of electromagnetism. Later physicists like Albert Einstein, Niels Bohr, Erwin Schrödinger, Werner Heisenberg and others followed his view in modern physics. This is a fifth point of my work. I compare Nagarjuna (Kumarajiva) with European scientific modes of thought for a better understanding of Asia. I do not compare Nagarjuna (kumarajiva) with European philosophers like Hegel, Heidegger, Wittgenstein. The principles and metaphysical foundations of physical sciences are more representative for European modes of thought than the ideas of Hegel, Heidegger and Wittgenstein and they are more precise. And slowly we are beginning to understand these principles. Let me take as an example the interpretation of quantum entanglement by the British mathematician Roger Penrose. Penrose discusses in the year of 2000 the experiences of quantum entanglement where light is separated over a distance of 100 kilometers and still remains connected in an unknown way. These are well known experiments in the last 30 years. Very strange for European modes of thought. The light should be either separated or connected. That is the expectation most European modes of thought tell us. Aristotle had been the first. Aristotle (384 - 322 Before Current Era) was a Greek philosopher, a student of Plato and a teacher of Alexander the Great. He told us the following principle as a metaphysical foundation: Either a situation exists or not. There is not a third possibility. Now listen to Roger Penrose: “Quantum entanglement is a very strange type of thing. It is somewhere between objects being separate and being in communication with each other” (Roger Penrose, The Large, the Small and the Human Mind, Cambridge University Press. 2000 page 66). This sentence of Roger Penrose is a first step of a philosophical generalization in a Whiteheadian sense. 6. Key terms: ‘The metaphysical foundations of modern science’ had been examined particularly by three European and American philosophers: E. A. Burtt, A.N. Whitehead and Hans-Georg Gadamer, by Gadamer eminently in his late writings on Heraclitus and Parmenides. I try to follow the approaches of these philosophers of relational views and of anti-substantialism. By ‘metaphysical foundations’ Edwin Arthur Burtt does not understand transcendental ideas but simply the principles that are underlying sciences. 7. Key terms: ‘Complementarity’, ‘interactions’, ‘entanglements’. Since 1927 quantum physics has three key terms which give an indication to the fundamental physical reality: Complementarity, interactions and entanglement. These three notions are akin to Nagarjuna’s (Kumarajiva’s) relational view of reality. They are akin and they are very precise, so that Buddhism might learn something from these descriptions and quantum physicists might learn from Nagarjuna’s (Kumarajiva’s) examples and views of reality. They might learn to do a first step in a philosophical generalisation of quantum physical experiments. All of us we might learn how objects are entangled or going arm in arm. [The end of the summary.]. (shrink)

What are the metaphysical foundations of Buddhism and modern science? Nagarjuna is not looking for a material or immaterial object which can be declared as a fundamental reality of this world. His fundamental reality is not an object. It is a relation between objects. This is a relational view of reality. This is the heart of Nagarjuna’s ideas. In the 19th century a more or less unknown Italian philosopher, Vincenzo Goberti, spoke about relations as the mean and as bonds between (...) things.

A piece of folklore enjoys some currency among philosophical Bayesians, according to which Bayesian agents that, intuitively speaking, spread their credence over the entire space of available hypotheses are certain to converge to the truth. The goals of the present discussion are to show that kernel of truth in this folklore is in some ways fairly small and to argue that Bayesian convergence-to-the-truth results are a liability for Bayesianism as an account of rationality, since they render a certain sort of (...) arrogance rationally mandatory.

This is a short, nontechnical introduction to features of time in classical and relativistic physics and their representation in the four-dimensional geometry of spacetime. Topics discussed include: the relativity of simultaneity in special and general relativity; the ‘twin paradox’ and differential aging effects in special and general relativity; and time travel in general relativity.

It is sometimes claimed that the Bayesian framework automatically implements Ockham’s razor—that conditionalizing on data consistent with both a simple theory and a complex theory more or less inevitably favours the simpler theory. It is shown here that the automatic razor doesn’t in fact cut it for certain mundane curve-fitting problems.

In some recent work, John N.Williams defends a new objection to the defeasibility theory of knowledge. But the objection is of wider interest, since Williams also suggests that this style of objection may undermine other theories of knowledge. I distinguish two versions of Williams’ objection. I then show that the first version relies on false conceptual principles, and the second relies on a specific and dubious conception of the goal of the analysis of knowledge.

Intuitively, a classical field theory is background-in- dependent if the structure required to make sense of its equations is itself subject to dynamical evolution, rather than being imposed ab initio. The aim of this paper is to provide an explication of this intuitive notion. Background-independence is not a not formal property of theories: the question whether a theory is background-independent depends upon how the theory is interpreted. Under the approach proposed here, a theory is fully background-independent relative to an interpretation (...) if each physical possibility corresponds to a distinct spacetime geometry; and it falls short of full background-independence to the extent that this condition fails.

The aim of this paper is to apply the metaphysics of John Duns Scotus in constructing a new conception of matter which does not stand in opposition to the mental realm, but is rather composed of both physical and mental elements. The paper is divided into four parts. Section one addresses Scotus’ claim that matter is intelligible and actual in itself. Section two aims to show that matter can be seen as a deprived thinking being. Section three analyzes Scotus’ conception (...) of place. The final section brings together the conclusions of the three preceding parts to confront the Cartesian psycho-physical problem anew and to suggest a viable solution. (shrink)

The importance of John Locke's discussion of persons is undeniable. Locke never explicitly tells us whether he thinks persons are substances or modes, however. We are thus left in the dark about a fundamental aspect of Locke's view. Many commentators have recently claimed that Lockean persons are modes. In this paper I swim against the current tide in the secondary literature and argue that Lockean persons are substances. Specifically I argue that what Locke says about substance, power, and agency commits (...) him to the claim that persons are substances. I consider the passages mode interpreters cite and show why these passages do not imply that Lockean persons are modes. I also respond to two objections anyone who thinks Lockean persons are substances must address. I show that a substance reading of Locke on persons can be sympathetic and viable. I contend that with a clearer understanding of the ontological status of Lockean persons we can gain a firmer grasp of what Locke's picture of persons looks like. Finally, once we are armed with a better understanding of Locke on substance, mode, and personhood, we can pave the way toward a more nuanced description of the early modern debate over personal identity.

The work of Thomas White represents a systematic attempt to combine the best of the new science of the seventeenth century with the best of Aristotelian tradition. This attempt earned him the criticism of Hobbes and the praise of Leibniz, but today, most of his attempts to navigate between traditions remain to be explored in detail. This paper does so for his ontology of accidents. It argues that his criticism of accidents in the category of location as entities over (...) and above substances was likely aimed at Francisco Suárez, and shows how White’s worries about the analysis of location were linked with his broader cosmological views. White rejects real qualities, but holds that the quantity of a substance is somehow distinct from its bearer. This reveals a common ground with some of his scholastic interlocutors, but lays bare a deep disagreement with thinkers like Descartes on the nature of matter. (shrink)

This paper is concerned with learners who aim to learn patterns in infinite binary sequences: shown longer and longer initial segments of a binary sequence, they either attempt to predict whether the next bit will be a 0 or will be a 1 or they issue forecast probabilities for these events. Several variants of this problem are considered. In each case, a no-free-lunch result of the following form is established: the problem of learning is a formidably difficult one, in that (...) no matter what method is pursued, failure is incomparably more common that success; and difficult choices must be faced in choosing a method of learning, since no approach dominates all others in its range of success. In the simplest case, the comparison of the set of situations in which a method fails and the set of situations in which it succeeds is a matter of cardinality (countable vs. uncountable); in other cases, it is a topological matter (meagre vs. co-meagre) or a hybrid computational-topological matter (effectively meagre vs. effectively co-meagre).

Literature in epistemology tends to suppose that there are three main types of understanding – propositional, atomistic, and objectual. By showing that all apparent instances of propositional understanding can be more plausibly explained as featuring one of several other epistemic states, this paper argues that talk of propositional understanding is unhelpful and misleading. The upshot is that epistemologists can do without the notion of propositional understanding.

There are many parts of science in which a certain sort of underdetermination of theory by evidence is known to be common. It is argued that reflection on this fact should serve to shift the burden of proof from scientific anti-realists to scientific realists at a crucial point in the debate between them.

Becoming is a process in which a thing moves from one state to another. In Section 1, the study will elaborate on the discussion of the Aristotelian causes taken broadly, primarily focusing on the relation between efficient and final causes. In Section 2, the study discusses the implications of Scotus’s conception of freedom, as it is reflected in the relation of the future to the past, for the efficient and final causalities. Similarly in Section 3 an examination of Scotus’s conception (...) of matter is conducted. Based on the ideas established in these sections, the study attempts to present an initial Scotistic view of becoming. -/- . (shrink)

The orgulity objection of Belot (2013) is recast in the form of a decision problem.

A growing number of decision theorists have, in recent years, defended the view that rationality is permissive under risk: Different rational agents may be more or less risk-averse or risk-inclined. This can result in them making different choices under risk even if they value outcomes in exactly the same way. One pressing question that arises once we grant such permissiveness is what attitude to risk we should implement when choosing on behalf of other people. Are we permitted to implement any (...) of the rationally permissible risk attitudes, is there some specific risk attitude that is required when choosing for others, or are we required to defer to the risk attitudes of the people on whose behalf we are choosing? This article elaborates on this question, explains its wider practical and theoretical significance, provides an overview of existing answers, and explores how to go about providing a more systematic account of how to choose on behalf of others in risky contexts.

An inequality in quantum mechanics, which does not appear to be well known, is derived by elementary means and shown to be quite useful. The inequality applies to 'all' operators and 'all' pairs of quantum states, including mixed states. It generalizes the rule of the orthogonality of eigenvectors for distinct eigenvalues and is shown to imply all the Robertson generalized uncertainty relations. It severely constrains the difference between probabilities obtained from 'close' quantum states and the different responses they can have (...) to unitary transformations. Thus, it is dubbed a master inequality. With appropriate definitions the inequality also holds throughout general probability theory and appears not to be well known there either. That classical inequality is obtained here in an appendix. The quantum inequality can be obtained from the classical version but a more direct quantum approach is employed here. A similar but weaker classical inequality has been reported by Uffink and van Lith. (shrink)

Like Lewis, many philosophers hold reductionist accounts of chance (on which claims about chance are to be understood as claims that certain patterns of events are instantiated) and maintain that rationality requires that credence should defer to chance (in the sense that under certain circumstances one's credence in an event must coincide with the chance of that event). It is a shortcoming of an account of chance if it implies that this norm of rationality is unsatisfiable by computable agents. This (...) shortcoming is more common than one might have hoped.

Many naive realists endorse a negative disjunctivist strategy in order to deal with the challenge presented by the possibility of phenomenologically indistinguishable halucination. In the first part of this paper I argue that this approach is methodologically inconsistent because it undercuts the phenomenological motivation that underlies the the appeal of naive realism. In the second part of the paper I develop an alternative to the negative disjunctivist account along broadly Meinongian lines. In the last section of this paper I consider (...) and evaluate a somewhat similar but rival view of hallucination developed by Mark Johnston. (shrink)
